Flame retardant mdf is a three-layer or multi-layer board material made of wood segments cut into veneer or thin wood by square planing. After flame retardant treatment of veneer, the board is glued with adhesive. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are glued vertically to each other. Flame retardant mdf is made of wood as the main raw material.
Fireproof board, its standard name is refractory board. It has rich surface color, grain and special logistics performance, but has certain fire resistance. Fire-proof board is a fire-proof sandwich sandwich board made of metal plate (aluminum plate, stainless steel plate, color steel plate, titanium plate, copper plate, etc.) as the panel, halogen free flame retardant inorganic modified core material as the core layer, hot pressing composite. Fire board veneer is three layers, relatively thick.
Fireproof mdf board, in fact, not it can fire, also occur combustion phenomenon, but its refractoriness is much higher than other materials, can adhere to a longer time in a high temperature environment. When this happens, it gives people more time and opportunity to escape. In addition to the characteristics of fire resistance, fireproof board can also be used as a decorative material, which is mainly because it has a very bright color and rich texture. And light high strength, sound absorption, sound insulation, green environmental protection, easy to process, economic and practical are the inherent characteristics of the fireproof board.
In the use of fire retardant mdf and fireproof board is also different:
1. Flame retardant board is a material that must be used in the decoration of public places.
The base material of flame retardant board is multi-layer plywood. The basic processing principle of symmetry and the adjacent veneer fibers are perpendicular to each other makes the physical and mechanical properties of the vertical and horizontal directions of plywood less different, uniform characteristics, stable shape, strong bearing capacity, easy processing and so on. It is widely used in all kinds of public places decoration with strict fire prevention and flame retardant requirements, high-grade family decoration, high-grade furniture, high-speed EMU carriages, sports venues and other grassroots partition modeling needs.
2. Fireproof board is just people’s habit, but it is not really afraid of fire, but has a certain fire resistance.
Fireproof board door panel, is to use fireproof board to do veneer, particleboard to do the base material (also useful density board), after the cabinet factory pressed to make. Compared with melamine board, fireproof board processing more trouble. Melamine board can be directly cut board, and the fireproof board needs to spray glue, the use of the press press for more than a day, in order to use.
