Anti-corrosion heat insulation board is a new generation of environmentally friendly and energy-saving roof and wall materials, and it is also an upgraded product of color steel plate.

Anti-corrosion heat insulation board is a new generation of environmentally friendly and energy-saving roof and wall materials, and it is also an upgraded product of color steel plate. At present, anti-corrosion heat insulation board is welcomed by more and more industrial enterprises for its excellent anti-corrosion and thermal insulation performance.

The anti-corrosion insulation board uses high temperature and high pressure materials, such as high weather resistance modified polyester film, aging resistance and ultraviolet chemical conversion layer, anti-corrosion alloy aluminum foil, weather resistance polymer chemical conversion layer, galvanized/aluminum zinc layer, high strength steel plate or aluminum plate, etc. Physical and chemical reactions solidify these materials together. This technology makes full use of the acid and alkali resistance of high weather resistance modified polyester film, corrosion resistance alloy aluminum foil and other materials, as well as the corrosion resistance of various chemical media, with a service life of more than 10 years.

The reflection coefficient of the anti-corrosion heat insulation board to light and heat is as high as 81%, so the heat insulation board can scatter about 81% of the solar heat and absorb only a small part. At the same time, its thermal conductivity is 2.93W/lower than that of the real composite material, compared with the thermal conductivity of the color steel plate as high as 40W/mk, so the anti-corrosion heat insulation board can form strong reflection and low thermal conductivity. In the high temperature in summer, the roof surface temperature can be reduced by 10-15 ° C, and the indoor temperature can be reduced by 5-10 ° C. So what are the factors that affect the service life of the anti-corrosion heat insulation board?

1. Product quality

Looking at the market, we found that the appearance of anti-corrosion heat insulation boards is similar, but the price is different. The performance indicators of "resin boards" of different manufacturers and brands are different. The surface of some resin boards seems to be bright and cheap. Some manufacturers have added a lot of oily additives to the composition ratio of the formula to make the board surface particularly smooth. After being exposed to outdoor wind and sun, the ingredients are easy to precipitate, resulting in poor quality and aging.

2. Use environment of anti-corrosion heat insulation board

Sandwich foam boards are subject to different external influences, which may affect the life of resin boards. In some areas, acids and alkalis are more corrosive and their service life will be relatively shortened.

3. Construction technology of anti-corrosion heat insulation board

Due to resource issues when installing and building resin panels, some customers do not have the experience of construction teams and even install them themselves in order to reduce costs, resulting in incorrect construction and short service life of resin panels. When we lay resin panels, it is necessary to hire experienced technicians.

4. It is related to the usage of surface ASA resin and co-extrusion technology

When buying synthetic resin panels, you should find a regular manufacturer or wholesaler of anti-corrosion insulation panels. Don't buy too cheap. The cost of real synthetic resin panels is relatively high.

Causes and treatment methods of dull surface of printed board

The surface of the printed board is relatively glossy, and there are many reasons for matte. In the production and processing process, everyone should pay attention to finding the cause of insufficient color and solve it, otherwise it will affect the use effect of the product. Under a certain influence, the following will introduce the reasons for matte and how to deal with it.
