Up to now, the building materials industry has developed rapidly, and many building materials have excellent performance. However, out of the requirements for the service life and safety of the building, the corrosion resistance and fire resistance of the building materials are required. The fire resistance of building materials directly has an important impact on the safety coefficient of the building, and thus its fire resistance should be considered when choosing building materials.
Aluminum veneer is mainly used in airports, stations, hotels, squares and other public occasions, so the fireproof effect of aluminum veneer has high requirements is very normal. Aluminum veneer itself does not exist separately "fireproof aluminum veneer" such a category, but the performance of the aluminum veneer itself makes its fire effect is very good, because it is mainly made of aluminum alloy plate processing, and spray paint on its surface, able to withstand high temperatures around 800 ° C. But even if it is about 800 ° C, it can be used in a variety of applications, such as the airport, station, hotel and other public places, so the aluminum veneer has a high fire effect is normal.
But even if the high temperature of about 800 ° C may not meet the requirements of all construction occasions, some use occasions may be higher temperature requirements, which involves a building material fire rating problem. Mainly indoor ceiling and wall decorative materials such as fire rating. This fire rating is mainly based on a series of professional tests and the results, according to EN13501-1, building materials combustibility can be divided into the following levels, respectively, A1, A2, B, C, D, E, F and other seven levels. Among them, A1, A2 level is a higher level of fire protection, we usually say that the fire level of rock wool is these two levels.
On the relevant data, aluminum veneer fire should be in the A2 level, but if attached to the back of the rock wool and other excellent fireproof materials, its fire performance greatly enhanced, that is, constitute what we call "fireproof aluminum veneer".
