The importance of pearl core board for fire door

Perlite fire door core board is actually made of expanded perlite as the main raw material, which is mixed with a certain proportion of machine high adhesive and chemical additives, and then through the baptism of multiple processes. The expansion perlite is natural perlite after high temperature calcination expansion, and so made out of the perlite fire door core board is pure natural pollution-free, the safety factor is very high.

In fact, expanded perlite is relatively light, is a new type of environmental protection material, and its thermal conductivity is not high, the use of temperature atmosphere is relatively wide, so perlite fire door core board is very practical. And expanded perlite chemical stability is also relatively high, and non-toxic, tasteless, so you think perlite fire door core board how!

The characteristics of perlite fire door core board

A, how about perlite fire door! Let's take a look at what its features are!   Perlite fire door core board is the main raw material of natural perlite calcined high-temperature expansion perlite, not only non-toxic and tasteless without radioactive elements, but also natural environmental protection, is not very good!

Two, perlite fire door core board thermal conductivity is very poor, so the combustion of the product is not very high, fire prevention, and perlite fire door core board moisture absorption capacity is small, chemical stability is very good, so it can also be moisture-proof, anti-corrosion, so it is very widely used.

Three, how about the perlite fire door core board! It is relatively simple construction, saving a lot of installation time, but also has the characteristics of light and high strength, the advantages of poor thermal conductivity, so the use of perlite fire door core board can not only heat insulation, but also sound absorption, is not very good!

The use of perlite fire door core board

Perlite fire door core board is widely used, which can act as steel fire door, wood fire door, anti-theft door and other filling materials. As a result of perlite fire door core board natural environmental protection, and also heat resistant moistureproof, so in a lot of firewalls, also can see its figure.   In fact, there are a lot of perlite fire door core plate specifications, which can also be processed according to customer needs, suitable specifications of products, so perlite fire door core plate can not only when the door filling, but also can be used in a large area of the firewall.
