What are the reasons affecting the service life of nano anti-corrosion heat insulation boards?

Nano anti-corrosion heat insulation board is a new generation of energy-saving roofing and wall materials, and an upgraded product of color steel plate. At present, nano anti-corrosion and heat insulation board is welcomed by more and more industrial enterprises for its excellent anti-corrosion and heat insulation performance.

High-temperature and high-pressure materials, such as highly weather-resistant modified polyester film, anti-aging and UV chemical conversion layer, anti-corrosion alloy aluminum foil, weather-resistant polymer chemical conversion layer, galvanized/aluminum-galvanized layer, high-strength steel plate or aluminum plate, and so on. For anti-corrosion and thermal insulation panels. Physical and chemical reactions cure these materials together. The technology makes full use of the acid and alkali resistance of materials such as highly weather resistant modified polyester film and corrosion resistant alloy aluminum foil, as well as the corrosion resistance of various chemical media, with a service life of more than 10 years.

Anti-corrosion heat insulation board has a reflection coefficient of up to 81% for light and heat, so the heat insulation board can scatter about 81% of the sun's heat and absorb only a small portion. Meanwhile, its thermal conductivity is 2.93w/m lower than that of composite materials, compared to color steel sheet, which has a thermal conductivity of up to 40W/mk, so the nano anticorrosion heat insulation board can form a strong reflection and low thermal conductivity. In summer high temperature, the roof surface temperature can be reduced by 10-15℃, and the indoor temperature can be reduced by 5-10℃. So what are the factors affecting the service life of nano anti-corrosion heat insulation board?

1. Product quality

Look at the market, found that the nanometer anti-corrosion insulation board appearance is almost the same, but the price is not the same. Different manufacturers, brands of "resin plate" performance indicators are different. Some resin boards look shiny and cheap. Some manufacturers add a large number of oily additives in the composition ratio of the formula to make the surface of the board especially smooth. After being exposed to the sun outdoors, the ingredients are easy to precipitate, resulting in poor quality and aging.

2. The use environment of nano anti-corrosion heat insulation boards

Sandwich foam panels are subject to different external influences that may affect the life of the resin panels. In some areas, acid and alkali are more corrosive, and the service life will be relatively shorter.

3.Nano anti-corrosion heat insulation board construction technology

Due to the resource problem when installing and building resin boards, some customers do not have the experience of the construction team, or even install it by themselves in order to reduce the cost, which leads to incorrect structure of resin boards and short service life. It is necessary to hire experienced technicians when laying resin panels.
