color steel tiles knowledge
Color steel plate, refers to the color coated steel plate, color coated steel plate is a kind of organic coating steel plate. Color steel plate is divided into single board, color steel composite board, floor board, etc.. Widely used in large public buildings, public buildings, movable house, and integrated housing walls and roof.

,,,Chinese name painted steel a Color steel tile referred to as the definition of a color steel plate with organic coating plate classification of single plate, Caigang composite panels, floor plate basic characteristics of heat insulation, light weight.

1 light weight: 10-14 kg / square meter, equivalent to brick wall 1/30.
2 thermal insulation: core material thermal conductivity: lambda <=0.041w/mk.
3 high strength: can be used for the construction of the ceiling envelope plate, bending resistance; general housing without beam column.
4 bright color: no surface decoration, color galvanized steel anti-corrosion layer to maintain a period of 10-15 years.
5 flexible installation: construction cycle can be shortened by more than 40%.
6 oxygen index: (OI) 32 (provincial fire products quality inspection station).

Main species
The substrate of the color steel plate is a cold-rolled substrate, a hot galvanized substrate and an electro galvanized substrate. Coating types can be divided into polyester, silicone modified polyester, PVDF two and plastic sol. The surface state of color steel plate can be divided into coated sheet, embossing plate and printing plate, color steel appliances widely used in construction and transportation industries, the construction industry is mainly used in steel plants, airports, warehouses and other industrial and commercial refrigeration roof of the building walls and doors, building color steel less.

Developing trend
First, the high quality substrate surface, shape and size precision of the substrate requirements are increasingly high, such as outdoor small zinc flower flat hot galvanized steel coil, no zinc flower smooth hot dipped galvanized steel coils in zinc alloy under heat up roll plating; indoor use such as galvanized steel coil, cold foil rolled plate and aluminum volume.
Second, to improve the pretreatment process and pretreatment of liquid, a small number of equipment, low cost to become the mainstream technology, continuous improvement of the stability of the pretreatment solution, corrosion resistance, environmental protection performance.
Third, note the development of new coatings, the general polyester, polyvinylidene fluoride (PVDF) and plastic sol was modified to obtain super color reproducibility, anti UV, anti sulfur dioxide and improve corrosion resistance; develop resistance to pollution, heat absorbing functional coatings.
Fourth, the equipment is more perfect. Such as the use of new welding machine, a new type of roller coating machine, improve the curing furnace, equipped with advanced automation instrumentation.
Fifth, because of the low cost, low cost, beautiful appearance, high sensitivity and high strength, the cold embossing technology becomes the development trend.
Sixth, pay attention to the diversification of products, functional, high-grade, such as deep stamping color coated plate, "grapefruit skin" color coated plate, anti-static color coated plate, color coated with pollution, high heat absorbing color coated plate, etc..
