The production process of color-coated aluminum coil includes cleaning and pretreatment, coil coating, curing and subsequent processing.
1. Cleaning and pretreatment
After the pre-treated aluminum coil is repeatedly cleaned and sprayed with water, the water can be reused, thereby reducing power consumption. It can improve the anti-corrosion performance analysis of enterprise products and can improve the adhesion of coatings.
2. Coil coating
The coating process is mainly divided into two stages, called primer and top coating.
3. Curing and subsequent processing
The aluminum strip passes through the curing oven, and the temperature is set at a regulated temperature to ensure that the volatiles on the aluminum strip are removed and the paint is completely cured. According to the needs of the coating system, the curing temperature is set between 200 and 300 degrees Celsius, which is a key technical point to ensure product quality.

Characteristics of aluminum coil
Because the quality of the aluminum itself is very light, and the thickness of the aluminum coil is not large, and has a certain strengthening, the weight of the foundation is also not high. The characteristics of low density and light weight also make aluminum coils useful in various industries.
Easy to handle
It is because the material of aluminum coil is very soft, plasticity is very strong, but also can ensure the later strengthening effect, so the efficiency of daily processing is also very high. Such plastic materials can be used well and can be processed in different types.
In fact, alloy aluminum itself has very good corrosion resistance, and its surface will have a layer of oxide film, naturally can also ensure good service life. Such products for long-term use, can also ensure corrosion resistance, not prone to problems.
Long service life
The service life of aluminum coil is still very long, and the surface can also be processed again, etc., plus its wide use, daily processing and production often see such aluminum coil. And its service life is longer, cost-effective aspect is also good.
What is cold rolled aluminum coil and hot rolled aluminum coil, what are the characteristics of each?
The difference between hot rolling and cold rolling is that cold rolling is rolling at the recrystallization temperature, hot rolling is rolling above the recrystallization temperature.
Each has its advantages and disadvantages.
Cold rolling mainly deals with plate that can not be strengthened by heat, and generally has high surface requirements, and single zero foil double zero foil and other ultra-thin materials can only be rolled by cold rolling.
The relative hot rolling is first to provide blank for cold rolling, and then many materials need high corrosion resistance, fatigue resistance, plasticity and so on, which need hot rolling.
What is colored aluminum coil?
Caitu aluminum coil, refers to the surface of the aluminum alloy color processing, for aluminum alloy performance is very stable, not easily corroded, general surface after special treatment can ensure that at least 30 years do not fade, more because of its small density, high hardness, the weight of per unit volume is the lightest metal materials, color aluminum, is a kind of new recently emerged in the field of Windows and doors profiles, compared with the plastic, The biggest advantage is that the firmness is incomparable, and the color is changeable, and will not always face the plastic steel is always questioned "toxic" two words. So in high-grade real estate doors and Windows, sun room, balcony packaging and other fields are widely used. Now, color coated aluminum coil has become one of the most popular top decorative materials. It is an environmentally friendly, durable and aesthetically pleasing green. As a decorative material, it has the following incomparable advantages of other products: uniform color, bright and clean, strong adhesion, durable, acid and alkali resistance, corrosion resistance, weathering resistance, decay resistance to friction, uv resistance, strong weather resistance.
Color coated aluminum coil product information:
Product category: polyester coated aluminium coil (PE), fluorocarbon coated aluminium coil (PVDF).
Polyester coated aluminium coil
Is a kind of anti-UV UV coating, polyester resin is used in the main chain of polymer containing ester bond as the monomer, adding alkyd resin, UV absorbent according to gloss and can be divided into matt and high light series. Especially suitable for interior decoration and advertising board.
Fluorocarbon coated aluminium coil
Is the use of fluoride alkyne as the basic monomer fluorocarbon resin, pigment, alcohol ester solvent, additives mixed from. After the film is cooked at high temperature,
The molecular structure of the coating is compact and has super weather resistance. Fluorocarbon coating can be divided into traditional fluorocarbon coating and nano fluorocarbon coating according to the surface film formation structure.
Especially suitable for indoor and outdoor decoration of public places, commercial chain, exhibition and advertising decoration and display
How to prevent oxidation of aluminum coil?
1. The storage environment of aluminum plate should be dry, bright, well ventilated and without corrosive climate.
2. Aluminum coils should be avoided as far as possible from leaking rain and snow.
3. Strengthen the management of rolling oil, and control its water content below 0.04 percent.
4. The packaging of aluminum coils should be sealed, and each roll should be put with an appropriate amount of desiccant.
5. Do not open the sealed package immediately when the product is transported from the low-temperature area to the area with high temperature and humidity.
6. The humidity of the wooden shaft and board of the packing box shall not exceed 18%, and the temperature of the colored aluminum coil shall not exceed 45℃.
7. When storing aluminum coils, it is strictly prohibited to store them together with chemical materials and damp materials.
