Oranges are made by mixing red and yellow, but a single orange pigment can produce a more vibrant and cleaner mix than the other oranges. Ancient artists had only one orange pigment available: natural orange ochre. It was highly toxic. Realgar, an arsenic containing orange pigment, was used in ancient Byzantium. It was also widely used by Venetian artists like Titian and Paolo Veronese during the Italian Renaissance.
In the early 20th century, the development of synthetic organic pigments such as benzimidazolone and pyrrole, along with cadmium, opened up new possibilities for oranges.

Names of orange pigment types
The Pigment Color Index identifies orange pigments by their prefix PO, which is based on the international index number. Here are some examples of orange pigments, along with their color images and properties guides. The samples are examples of the pigments used, but may not accurately reflect their actual colors.

PO5 (Pigment Orange 5)
b-Naphthol scarlet
Color description: Very reddish-orange
Transparency/Opacity: Semi-transparent
It is an excellent mixing color. When diluted with white, it has a pinkish undertone. Pigment Orange PO5 has a mixed reputation when it comes to lightfastness, especially in thin layers or watercolor. If this is a concern, you can use Pyrrole Orange PO73 or Benzimidazolone Orange PO36. PO5 in watercolor is extremely staining.

PO16 (Pigment Orange 16)
Azo Orange
Reddish orange
Transparency/Opacity: Highly transparent
C.I. 16 Pigment Orange is a little more reddish. Pigment Orange 13, Pigment Orange 34. It can be used for C.I. and printing inks. Pigment Yellow 12. Resins are transparent but have poor flow characteristics.

PO17 (Pigment Orange 17) - Azo Orange
Azo Orange
Reddish orange
Transparency/Opacity: Clear
Azo Orange, a slightly yellower version of Beta-Naphthol Scarlet Po5, is the cousin to Pigment Orange. This pigment is not lightfast. Try Pyrrole orange (PO73) as a lighter alternative.


PO20 (Pigment Orange 20) - Cadmium Orange
Cadmium Orange
Bright Warm Orange
Transparency/Opacity: Opaque
Cadmium orange is created by mixing Cadmium Selenide (PY35) with Cadmium Yellow. Pigment Orange PO20, like other cadmium-based pigments is an intense color that works best when mixed with other pigmented colors. Combine it with Phthalocyanine Green PG7 and Titanium White PW6 to create subtle greys. The metal cadmium is toxic, but it cannot be absorbed into the body. This means that the risk for artists is minimal. However, special precautions should be taken not to inhale dry cadmium paints. Cadmium orange is opaque and therefore not suitable for glazing. Try Benzimidazolone Orange PO36 or PO62 or Pyrrole Orange PO72 or PO73 for a more transparent shade of orange. These alternatives have a higher color chroma level than Cadmium orange.

PO36 (Pigment Orange 36) - Benzimidazolone Orange
Benzimidazoline Orange
Reddish orange
Transparency/Opacity: Semi-transparent to semi-opaque
The Benzimidazolone Pigments are a modern group of synthetic organic pigments in red, yellow, and orange. These pigments are known for their vibrant colors and lightfastness. They can be used in industrial colorants as well as artists' paints. It can be used to replace red on the palette because it has a strong cast of red. It produces deep maroon shades when mixed with Dioxazine Violet PV23.


PO43 (Pigment Orange 3) - Perylenone Orange
Perylenone Orange
Color description: Medium to orange red
Transparency/Opacity: Semi-opaque to transparent
Perylenone Orange was introduced into artist paints during the 1960s. It is less reddish than Benzimidazolone Orange PO36 and Beta-Naphthol Scarlet PO5, but still has a slightly reddish tint. Mix Phthalocyanine Blue with Perylenone Orange (PO36) to create a neutral gray.

PO48 (Pigment Orange 48) - Quinacridone Orange
Quinacridine Orange
Color description: Brownish orange, with golden undertones
Transparency/Opacity: Semi-transparent to transparent
Pigment Orange 48 Quinacridone Orange, an earthy yellow pigment is a great alternative to earthy colors because it has the vibrancy and high-chroma of natural earthy colours. Mix it with other blues to create a variety of golden greens. Some sources claim that Pigment Orange PO48 is no longer available and has been discontinued in artist paints. However, we couldn't find any evidence to support this.


PO49 (Pigment Orange 49) - Quinacridone Gold (Discontinued)
Quinoacridone Colors
Color description: Deep orange with golden undertones
Transparency/Opacity: Translucent to transparent
Many artists lamented the loss of Pigment Orange Po49 when the car manufacturers stopped producing it in 2001. This was a great glazing color that had a primary earthy yellow tone, but when diluted became a bright golden-yellow. Quinacridone Gold pigments are available in a variety of shades, including this sample. They all use a mix of yellow and orange transparent pigments.


Nickel Orange PO59 (Pigment Orange 59)
Nickel Orange
Color description: Light yellowish Orange
Transparency/Opacity: Transparent
Pigment Orange PO59, a transparent, bright orange, is made from a complex nickel azomethine. It is ideal for glazing techniques.

PO62 (Pigment Orange 62) - Benzimidazolone Orange
Benzimidazolone Orange 62
Color description: Light yellowish or reddish-orange
Transparency/Opacity: Semi-transparent to semi-opaque

The Pigment Orange, PO62 has a more yellow tone than PO36. Benzimidazolones are a class of modern organic synthetic pigments that are known for their vibrant colors and high lightfastness. The pigment Orange PO62 has a moderate pigmentation, so it won't overpower any mixture. Combining Indanthrene Blue PB60 will create a neutral dark shade.


PO67 (Pigment Orange 67) - Pyrazolquinophthalone Orange
Quinophthalone Orange
Color description: Bright, orange-red
Transparency/Opacity: Semi-transparent
Pigment Orange Po67 A reddish-orange pigment that can replace red in a palette. Pyrazolquinophthalone Orange has excellent lightfastness.


PO71 (Pigment Orange 71) - Pyrrole Orange
71 Pyrrole No. 71
Reddish orange
Transparency/Opacity: Transparent
The name pyrrole comes from the Greek pyrrhos which means "fire". This family of pigments includes modern oranges and reds that are well-deserving of their name. Pyrrole orange was developed originally as a car paint pigment. However, it can be used by artists to create a transparent substitute for cadmium (it's better for glazing) and to produce gray-greens.

PO73 (Pigment Orange 73) - Pyrrole Orange
Pigment Orange 73 Colour
Reddish orange
Transparency/Opacity: Semi-transparent to semi-opaque
PO73 is another orange pyrrole, which tends to be more red in color than PO71. It is, however, very similar. This is a very staining color in watercolors and it's difficult to remove once applied.

Pigment red 202 manufacturer say, Natural and synthetic organic pigments can be divided into two groups: colored organic compounds. Nowadays, synthetic organic pigments have become common. Organic pigments come in a wide range of colors and many different varieties.

Inorganic pigments can be oxides or metal salts insoluble in metals. Inorganic colors are separated into two categories: natural inorganic and artificial inorganic. Mineral pigments are natural inorganic pigments.

The organic pigments are divided into different categories such as monoazo or disazo pigments, lakes, phthalocyanine pigments, and condensed ring-shaped pigments.

Carbon black, metal oxides, or salts, such as barium, iron, titanium, zinc, and cadmium are the main inorganic pigments.

Organic pigments are bright, have a wide range of colors and a diverse structure, but they have low light resistance and poor weather resistance.

Inorganic pigments are resistant to the sun, weather, high temperatures, solvents, and have a strong hiding power. However, the color spectrum of these pigments is not complete. Inorganic pigments are not as brightly colored as organic pigments.

In general, the term "environmentally friendly" is relative. The industry sets different standards for judging whether a pigment is environmentally friendly. In general, harmful pigment components, such as toxicity, can only be found within a limited range.

In general, the term "environmentally friendly" is relative. The industry sets different standards for judging whether or not they are environmentally-friendly pigments. The harmful components, or toxicity of pigments are generally limited (meeting certain standards) and pigments which do not cause pollution and pose no threat to human health can be considered environmentally friendly.

In terms of their chemical composition and toxicity, pigments are divided into two main categories: organic pigments and non-organic pigments. Different standards are used to determine whether or not they are environmentally-friendly pigments. Inorganic pigments are evaluated based on eight heavy metals - antimony, arsenic cadmium chromium mercury lead chromium cadmium barium. There are many other standards. In the case of electronic appliances and coatings and plastics the EU EN71-3 is used. When they are used for industries that have direct contact with foods, like non-stick pans, the US FDA standard is used.

Two evaluation methods are available: the first is to measure the heavy metal content in the pigment, while the second is to measure the amount of heavy metals that leak out after the pigment has been made into a finished product. For organic pigments the research into the toxicity involves many areas, including: acute toxicity; irritation of the skin and mucous tissues; subacute toxic contact with continuous exposure to the pigments and other organic pigments.

Colorants, primarily divided into pigments and dyes, play a crucial role in various industries. As a professional organic pigment manufacturer, this overview focuses on pigments, which are classified into inorganic and organic categories based on their chemical composition. Inorganic pigments include oxides, chromates, sulfates, carbonates, silicates, and others. Organic pigments, on the other hand, can be classified by their chemical structures into azo pigments, phthalocyanine pigments, quinacridone pigments, and more.

The history of synthetic organic pigments began in 1899 with the creation of Lithol Red, marking a significant milestone. Further developments included the invention of yellow and orange monoazo pigments in 1909 and phthalocyanine blue pigments in 1935. The global organic pigments industry has since evolved for over 110 years.

The development of China's organic pigment industry can be divided into three key phases. The first phase, from the 1950s to the 1970s, was a period of slow growth during the planned economy era, where production was limited to a few factories such as those in Beijing and Tianjin. The second phase, from the 1980s to the 1990s, saw rapid growth, driven by economic reforms and foreign investments. By the early 21st century, China entered a comprehensive development phase, with significant improvements in production capacity, product quality, and innovation. In 2008, China's pigment production reached 185,000 tons, with exports of 75,000 tons, reflecting its growing status as a global leader.

Similarly, China’s inorganic pigment industry also experienced steady development after the country's founding, with rapid expansion during the reform era. By 2008, production reached 1.55 million tons across about 120 manufacturers, fulfilling both domestic demand and international market needs.

China’s pigment industry growth has been closely tied to economic reforms and global shifts in the industry. As demand patterns, labor costs, and environmental regulations in developed countries pushed the industry to relocate, Asia—particularly China—emerged as the new center of pigment production. By the 1980s, the industry had shifted from Europe and North America to Asia, fueling China’s rise as a global powerhouse in both pigment production and trade.

1. Start the concrete pump and run empty. If the temperature is low, the empty operation time should be longer, because the temperature of the hydraulic oil will only be able to pump concrete if it rises above 15℃. Do not use pressure test (overflow valve high pressure overflow) to speed up the rate of heating.

2. A certain amount of clean water is added to the hopper of concrete pump to moisten the hopper, distributing valve and concrete conveying pipeline of concrete pump.

3. Add a certain amount of cement mortar into the hopper to lubricate the entire concrete conveying pipeline.

4. After the cement mortar is injected into the hopper, the mixing shaft should be reversed for a few weeks to allow the two sides of the concrete pump hopper to be fully lubricated by the mortar, and then the mixing shaft should be turned to feed the mortar into the distribution valve box through the hopper throat.

5. Do not pump out all the mortar inside the hopper when the pump is started. The mortar should be kept above the level of the mixing shaft of the hopper and pumped together after the concrete is delivered and added to the hopper.

China galvanized steel coil supplier said that construction and light industry are the main markets for galvanized coils, and the demand is about 30% of the galvanized coil. According to the speed of national economic development and the previous consumption base, the total demand in the first half of the year is about 4 million tons, equivalent to 180,000 tons of refined zinc consumption.

From the demand for galvanized steel coils in the home appliance industry, air conditioners are the main products for consuming galvanized steel coils. The back panel of the air conditioner indoor unit and the cabinet, the inner part, the outer casing of the outdoor unit, and the interior are all made of the galvanized coil, and an average of one air conditioner consumes 22 kg of the galvanized coil. In addition, each washing machine consumes approximately 8 kg of galvanized rolls, and each refrigerator consumes approximately 3 kg of galvanized rolls.

The automotive industry is also a major industry for consuming galvanized coils, which is much larger than the home appliance industry. Since 2006, the output of China's automobiles has increased rapidly, especially in the sedan. According to the calculation of about 350 kg of galvanized coil per vehicle, the demand for galvanized coils in China's auto industry is at least 3.1 million tons per year.

The construction industry needs a large number of galvanized coils to manufacture ventilation ducts. For example, a medium-sized building requires more than 25,000 square meters, and each specification has a total of 200 tons. Of course, this is not a waste of processing. At present, there are many large projects under construction in the country, and the demand is also very large.

Now the rapid development of science and technology, a lot of advanced equipment has been widely used, high quality PPGI corrugated roofing sheet is also so, with excellent performance, has been recognized by the industry, the following takes you to understand in detail.

PPGI corrugated roofing sheet area calculation rules:
1. Outdoor stairs and walkways are calculated according to the sum of natural projection areas;

2. The volume area is calculated by the length and width of the outer wall and multiplied by the number of floors;

3. Total area =1+2+3;

4. The canopy is calculated by half of the horizontal projection area;

5. Unless otherwise specified, the calculation method of engineering quantity shall be settled in accordance with the above calculation formula;

6. There are two stairs in the standard house, each one of the left and right gables. Each stair is 4.5 square meters.

PPGI corrugated roofing sheet for sale, the choice of color coated plate mainly refers to the mechanical properties, substrate type and coating weight, color aluminum plate, front coating properties and reverse coating properties of the choice. Use, corrosive environment, service life, durability, processing and deformation degree are important factors to consider when choosing PPGI roofing sheet.

Factors such as service life and durability are selected. Aluminum-magnesium zinc plate price, anticorrosion is one of the main functions of a painted plate, the type of substrate and coating weight is the main factor affecting the corrosion resistance of painted plate, the construction of painted plate usually choose hot dip galvanized substrate and hot dip aluminum-zinc alloy substrate, mainly because the two kinds of substrate corrosion resistance is good.

The choice of positive coating performance mainly refers to the choice of coating type, coating thickness, coating color difference, coating luster, coating hardness, coating flexibility, adhesion, coating durability, and other properties.

The commonly used topcoats are polyester, silicon-modified polyester, high-durability polyester, and polyvinylidene fluoride. There are certain differences in hardness, flexibility, adhesion, and durability of different topcoats. Polyester is the most widely used coating; Aluminized zinc coil, silicon-modified polyester modified by organosilicone, has high durability and luster. High durability polyester not only has the advantages of polyester but also improves the durability and has high-cost performance. Polyvinylidene fluoride has excellent durability and coating flexibility. Shanghai aluminized zinc plate, the top coating is mainly determined by the use, corrosive environment, service life, durability, processing mode and degree of deformation and other factors.

Although roll forming of high-quality GL Galvanized Steel Coil is the most commonly used colored plate forming method, for the production of roof panels and wall panels, there may be a need for blank holder or other accessories, sometimes also need to be as large as possible to improve the bending part of the bending radius. It is also important to avoid scratches on the coating surface during the blanking process, which can be avoided by applying polyurethane or hard plastic to the die.

Proper die clearance should be maintained during the pressing of GL galvanized steel coil. Embossing is also a type of color-coated plate forming, the embossing process to ensure that the coating and coating are not damaged, in order to ensure that the color painted plate durability is not affected, also need a low enough embossing sharpness and depth. Stamping, grooving, and punching are other forming methods of the painted plate.

For these molding methods, the influence of many factors discussed previously, such as mold clearance and paint flexibility, is also important. For example, stamping methods are used to produce roofing corrugated panels for use in rural areas.

The following awareness and care must be taken in the field construction of GL galvanized steel coils to ensure the good performance of the painted steel plates. Handling abrasions usually present as scratches or backside paint particles adhering to the surface of the painted steel plate. Defects arise from poor handling, inadequate paint curing, and irregular surface conditions. Degree of solidification, hardness, and lubricity of paint affect abrasion defects.

Good roller lubrication and a suitable back coat will help to reduce abrasions. Sometimes a transparent, strippable film can be applied to the surface of the steel plate to avoid handling abrasions. Scrapes may occur in the hoisting in the baling factory. In order to avoid scrapes caused by bending, the hoisting equipment of long bales should be able to support most of the length of bales. Bundles must be fixed vertically and horizontally.

Direct contact with other objects, such as structural parts, must be avoided when transporting GL galvanized steel coils in vehicles. When using forklifts to carry, care must be taken to ensure that the bales do not bend excessively or cause steel plate abrasions.

A feasible method to prevent the speed of aging of the GI steel coil in advance.

GI steel coil with spangles made in China used for a long time or not used for a long time may occur aging, why to say it, long-term construction or storage will be exposed to the sun. Aging occurs after a long time of exposure to light, which we cannot avoid. However, we can prevent and reduce the aging rate in advance in ordinary times. So what should we do?

The first necessary condition for aging or photochemical reaction of PPGI corrugated roofing sheet is that the surface composition of the GI steel coil can absorb radiation energy. Secondly, the absorption of molecular radiation energy is greater than the molecular bond energy, the color coating can occur degradation. The shorter the wavelength, the higher the energy.

According to the above theory, the aging of the high-quality PPGI corrugated roofing sheet in the atmospheric environment is that the coating molecules absorb the energy of the ultraviolet band in the sunlight which is higher than its molecular bond energy, leading to the degradation of the coating molecules. With the aging of the coating, the base material body is gradually lost, and the coating surface gradually becomes rough and lose light. This loss of base material eventually leaves relatively stable pigment particles in the form of an unbonded powder on the coated surface, a process known as pulverization.

To sum up, there is a big difference in the aging resistance of PPGI corrugated roofing sheet with different coating thickness, the aging resistance of thin coating color coating board is poor, the aging resistance of normal thickness coating is relatively good.

Therefore, it is not feasible to reduce the production cost of PPGI corrugated roofing sheet by reducing the thin coating, which will inevitably bring serious quality problems.

2, if the use of organic solvents to wipe the surface of the galvalume steel coating steel coil, the surface may cause the loss of galvanized coating or peeling, please pay full attention.

3, if the attachment of oil and other foreign bodies, may affect the performance of aluminum zinc steel coil, please pay full attention.

4. If the processing degree is high, the zinc layer may be damaged, please confirm before use.

5, with the passage of time, the galvalume steel coating steel coil may be reduced processing performance, tensile deformation and other conditions, in order to prevent this situation, it is recommended to use as soon as possible.

1. Mechanical property is an important index to measure the formability, is to determine and adjust the important parameters of the processing process, so high-quality PPGI corrugated roofing sheet processing should be considered first.

2. Pencil hardness, T bend, impact power, and other indicators are closely related to the processing performance, so it should be given full consideration.

3. The shape of the parts is complex, the degree of deformation is large, should use multi-pass forming. If a forming may be due to excessive deformation damage PPGI corrugated roofing sheet coating and substrate adhesion.

4. The processing should be based on the shape of the mold, deformation characteristics, process conditions and other factors to set the appropriate gap, gap setting should consider the thickness of PPGI corrugated roofing sheet coating.

5. Most of the high-quality PPGI corrugated roofing sheet coating can be used as a solid lubricant and can meet the lubrication requirements of the most forming process, some coatings can be adjusted by the formula to improve the lubricity of the coating. If the lubrication of the coating is insufficient, the lubrication can be improved by means of oil coating, wax coating, and protective film stripping. However, it should be noted that wet lubricant is easy to absorb dirt, should be removed before the installation of the painted sheet. Exfoliate protective film should be removed as soon as possible after construction.

The cold rolled steel coil factory in stock introduces that the traditional coatings can be divided into several categories. The top-grade coatings are fluorocarbon coatings, which can resist corrosion for almost 20 years. Generally from steel mills to distribute in the form of drums. We often see the color steel plate refers to the processed plate, the thickness of which is about 50 to 100 mm. It is composed of filler in the middle and color steel plate on both sides.
Among them, the thickness of the color plate is 0.4mm, 0.5mm, 0.6mm and other different thicknesses. The middle layer can be polyurethane, rock wool or foam plastics. Because of the special profiles, the construction speed of the factory building constructed with color steel sheets is very fast (such as Xiaotangshan Hospital in SARS), but the strength is low. The base plate of color coated steel sheet is cold rolled, hot galvanized and electro galvanized. The types of coatings can be divided into polyester, silicone modified polyester, polyvinylidene fluoride, and plastic sol.
