Perlite Fire Door Core Board

Description

Perlite fire door core board is a new type of fire door core filling material made of expanded perlite and adhesive (sometimes need to pre-embed the skeleton), after being stirred evenly by a special stirrer and under pressure. Expanded perlite is a lightweight, multi-functional new material. It has the characteristics of light density, low thermal conductivity, good chemical stability, wide operating temperature range, low moisture absorption capacity, non-toxic, odorless, fireproof, sound absorption, etc. It is widely used in various industrial sectors. Therefore, the fire door core board produced with expanded perlite as the main raw material has strong adhesion, rapid cold pressing and solidification, high strength of the finished product, small thermal conductivity, moderate bulk density, good hydrophobicity, salt resistance, acid and alkali resistance, and resistance. Freeze-thaw and high temperature, heat insulation and flame retardant, non-combustible and non-toxic under high temperature and high fire, stable performance, fire resistance up to A1 level, in line with the new national standard for fire doors on fillers.


Perlite Fire Door Core Board


The expanded perlite used is natural perlite ore, which is a hollow honeycomb-shaped particle spherical body that is instantly expanded at a high temperature above 1300 ° C. It is a non-combustible porous material of A1 grade and has a low thermal conductivity. The core board is a natural green and environmentally friendly ideal product. From the entry of raw materials to the completion of finished products, the entire manufacturing process has undergone strict and meticulous production and inspection, and is widely used in the interior filling of fire doors in public buildings and civil buildings. When a fire occurs, the product not only does not burn, but also does not release toxic fumes, and the fire resistance can last for more than 2 hours. It can act as a fire barrier to prevent the spread of the fire.
