The flame-retardant board is a kind of fire-retardant board which is more resistant to the external environment. Its main functions are climate resistance, durability, steam treatment, high temperature resistance and boiling water resistance.
The second kind of fire-retardant board is a kind of relatively damp resistant fire-retardant board, which can withstand short-term immersion in cold water and can be used at room temperature. It is generally used for furniture manufacturing and general building purposes.
The third kind of fire-retardant board is water-resistant fire-retardant board, which can withstand short-term hot water immersion and long-term cold water immersion.
The fourth kind of fire-retardant board is the non moisture resistant fire-retardant board, which is generally used for indoor use with dry weather in the north. It is mainly used for testing and general purpose fire-retardant board, including ash, basswood, birch, poplar, elm, etc.
Performance characteristics of flame retardant board
① The fire-retardant plywood has small hygroscopicity, stable water absorption thickness expansion rate, excellent moisture-proof performance, and does not affect the second processing of the facing, paint, etc;
② The free formaldehyde emission of the product is less than or equal to 4.0mg/100g, which is far lower than the national standard E1 grade 9.0mg/100g;
③ Excellent flame retardant performance: Class B of GB8624-2006 classification of flammability of building materials and products GB / t8625-2005 test method for flammability of building materials, flammability materials;
④ It has high chemical stability and excellent aging resistance;
⑤ MOR, MOE, IB and other physical and mechanical performance indexes are all up to class a requirements of national standard for superior products;
⑥ Fire retardant plywood is safe and environmentally friendly, and the combustion residue is non-toxic and pollution-free;
⑦ It does not damage the veneer, adhesive and machining performance of fire-retardant plywood;
⑧ The fire-retardant plywood has excellent screw holding force and does not corrode metal links.
