Buy coated aluminum coil

 

Buy coated aluminum coil with flat and smooth surface, with strong compactness, which can effectively prevent moisture, oxygen, and corrosive components in the air. The acid and alkali resistance of color coated aluminum is about 4 times that of traditional paint color-coated coils, which effectively improves the service life in humid and strong acid environments. The top coats of commonly used in aluminum coil coatings include polyester (PE), polyurethane (PU), silicon modified polyester (SMP), fluorocarbon (PVDF), high weather resistant polyester (HDP), primer and back coat The varieties are epoxy (EP), polyester (PE), polyurethane (PU) and so on.


color coated aluminum coil

The production process of color coated aluminum coil are:
First of all, it is necessary for color coated aluminum coil manufacturers to perform a complete chemical pretreatment on the surface of the sheet before coating, to completely remove the surface dust, oil stains, and oxide films. Therefore, the aluminum coil must undergo pre-treatment processes such as dust removal, degreasing, alkaline washing and cleaning. The operation methods and level of operation control of these processes have a decisive effect on the quality of the pre-treatment.
 
The production of color coated aluminum coil is to use straight hanging parts, spray them in a straight direction in an electrostatic field through spraying machinery, and then send the hanging parts to the oven to bake the paint. Repeated operations to form a paint coating. Whether the spray coating is uniform or not has great contact with the equipment selected by the color coated aluminum coil manufacturer.
 
The spraying process is often used on aluminum sheet coils, while aluminum composite panels and aluminum honeycomb panels are rarely used. Generally, painted aluminum coil manufacturers use the three-coating and two-baking process for plain paint, and the four-coating and two-baking process for metal paint.

Differences between PS and CTP base plate

图片
With the increasing maturity and the rapid development of CTP technology, as well as the declining of price, CTP technology has been more and more welcomed by the majority of printing practitioners, usage of CTP plates have the potential trend to catch up with the traditional PS plate. The overall requirements of the printing plate is very high, especially the current CTP plate is mostly used for high-grade color printing plate, to ensure the quality of the plate, the plate based apparent quality is the premise. The characteristic of CTP technology is the quality of CTP based plate, such as the apparent quality, physical property and electrolytic performance. The aluminum plate base is widely used according to CTP plate technical requirement. The difference between CTP plates and PS plate on the apparent properties of aluminum plate base are as follows. The basic appearance requirements of the aluminum base plate is clean and smooth, no cracks, corrosion pits, air vents, scratches,...

Introduction of aluminum foil insulation material

图片
Aluminum foil insulation material is the best thermal insulation material at present in the world. It has the advantages of light weight, low thermal conductivity, good heat resistance, aging resistance, easy combustion with other substrates, bonding does not produce droplet and other excellent properties. On the application, it is widely used in building roofing, wall, ceiling, floor, doors and windows as insulation materials. Aluminum foil itself is a good conductor of heat, directly used basically has no heat insulation, but accelerate the heat loss, so when used the insulation cotton is wrapped inside the aluminum foil . It has the functions of heat insulation, waterproof, moisture-proof and so on. Its solar radiation absorption coefficient is very low, which can insulate most of the heat transfer. Introduction of advantages of aluminum foil insulation material: (1) Simplification of structure to avoid waste. (2) It is unnecessary to set roof exhaust system. (3) Waterproof lay...
