What is composite plate
Literally, a composite plate is a plate made of two or more materials. In fact, in view of the plate with different material, the concept of composite plate and production methods are different. In daily life, often used to metal composite board, wood plastic composite board and glass fiber reinforced plastic composite board.
One, glass fiber reinforced plastic composite plate
There are many different types of glass fiber reinforced plastic plate, glass fiber reinforced plastic grille plate, plane glass fiber reinforced plastic plate, glass fiber reinforced plastic plate and so on. Its main production principle is glass fiber yarn, glass fiber felt, mesh cloth and some other glass fiber products and resin synthesis production. Its production process has molding, hand paste, pultrusion, spraying and so on.
Its structural advantages are:
1, glass fiber staggered textile and resin fully soaked, so that the grid maximum corrosion resistance.
2. The overall structure will evenly distribute the load, which is conducive to the uniform force of the grid installation and its installation support structure.
3, the glossy surface and oblique grid surface make the grid has a self-cleaning effect.
4. The surface concave surface makes the grille with anti-slip performance, and the anti-slip effect of the sand surface is better.
Its disadvantages are:
1, glass fiber reinforced plastic elastic modulus is low.
2, glass fiber reinforced plastic long-term temperature resistance is poor, can not be used at high temperature for a long time.
3, FRP is prone to aging phenomenon, in ultraviolet light, wind yarn rain and snow, chemical media, mechanical stress and other actions easy to lead to performance decline.
4, glass fiber reinforced plastic (FRP) interlayer shear strength is low, the interlayer shear strength is borne by resin, so it is very low.
Two, wood plastic composite board
Unlike fiberglass composite panels, WPC panels are made of wood only, and no other materials are involved. The scattered and scattered sawdust and thin plate through the combination of adhesive, in the outer layer of the whole plate polymerization.
Its advantages are:
1, good processing performance
2, can turn waste into treasure, can achieve 100% recycling
3. Wide sources of raw materials
4, excellent adjustable performance
Its disadvantages are:
The quality of wood-plastic composite board is relatively poor, so the use of the occasion is limited, mainly in the home life application. Wood-plastic wall, wood-plastic door panel. Wood plastic floor, etc.
Three, metal composite plate
The production principle of metal composite plate is basically the same, and the method of melting is used to melt two or more kinds of metal of different materials together. Common are aluminum alloy, stainless steel, etc., the main purpose is to enhance the performance of the sheet metal itself. Such as a single metal iron used for a long time easy to rust, if you add some corrosion resistant materials in it, it can largely solve the problem of easy to be corroded.
General single plate can not meet the specific use needs and conditions, will be through other methods to enhance their performance. The principle of composite plate is on the original basis, greatly improve their own performance of the shortcomings.
1, enhance their own performance, such as: wood plastic composite board can enhance their own bearing capacity and strength on the original basis;
2, improve the performance of comprehensive, such as: metal composite plate can greatly improve and overcome the shortcomings of their poor corrosion resistance;
3, comprehensive performance (innovation) such as: can be a variety of different performance integrated together, produce new products, glass fiber reinforced plastic sheet even so
