Standard introduction:
The GB8624 building materials and products combustion performance classification test is divided according to ground materials and non-ground materials, and then determine which grade to choose before performing specific tests.
Level introduction:
There are two standards for the classification of the combustion performance of building materials in China: "Classification Method for Combustion Performance of Building Materials" and "Classification Method for Combustion Performance of Building Materials and Products" (GB8624-2012). Among them, one of the major changes in GB8624-2012 and GB8624-2006 is to classify the classification of the material's combustion performance from A1, A2, B, C, D, E, and F to A, B1, and B2. And B3.
Product advantages:
Flame retardant board has low hygroscopicity, stable water absorption thickness expansion rate, and good moisture resistance. It is especially suitable for secondary processing of finishes, adhesives, paints, etc. It has strong grip screws, no corrosion, long-term flame retardancy stability and excellent resistance Aging. It can be made of veneer, can be carved, drilled, and can be pitted.
The main purpose:
1. Used for hanging boards, wall boards, showcase boards, sound-absorbing boards;
2. Used for all kinds of office and hotel furniture, fire doors, ceilings, screens, partitions;
3. Used for flame retardant reinforced flooring substrate and flame retardant door skin substrate.
