1. Density board in exhibition: generally, low density board and medium density board are used. The processing technology of density board is that pine wood and other logs are processed into small pieces, and then crushed into fine powder. Paraffin wax, glue and other materials are added to press the powder into board again through high temperature. The processing technology of low density / medium density board is not too poor, However, the technological process of MDF with different strength needs strict parameter control to ensure that the quality and strength as well as formaldehyde and other additives do not exceed the standard, so as to meet the national requirements.
2. The fireproof board is a kind of density board with a layer of flame retardant coating on the surface, which has the effect of flame resistance. The thickness is 0.6mm/0.8mm/1.0mm/1.2mm/1.5. The thickness of the thinnest one is the thickness of a piece of office paper. Its surface can be selected according to the requirements. The surface has smooth surface and pockmarked surface. It is generally used on the surface of wooden body and pasted with special glue, The construction is convenient. The thickness of the exhibition is 08mm.
3. Plywood used in exhibition is also called multilayer board, which is generally called composite board in China. For example, three plywood, five plywood, nine plywood, etc. It is commonly called plywood in the world, such as: 3cm, 5cm, 9cm, 12cm, 15cm, 18cm, etc. It is composed of a two-layer structure, mainly the surface of the single plate and sandwich plate. The veneer is made from log cooking and rotary cutting. The thickness is between 0.4 ~ 0.5mm theoretically. The medium plate is also a thick skin made of log cooking and rotary cutting. The thickness of the middle plate varies with the thickness of the plywood, and the thickness changes accordingly. Used to strengthen the surface in the exhibition.
4. It can be imagined that the main material of particleboard used in the exhibition is particleboard. The particleboard is slightly processed and pressed by adding some additives. The process is relatively simple and the raw materials are also cheap. It is a cheap substitute of density board. The strength and other properties are much worse than that of density board. There are problems such as easy damage. But after the surface is coated, if you don't look at the section, you can't see any problems.
In addition, there is a moisture-proof board, in fact, the density board added moisture-proof agent, the cross-section is dark green, similar to density board
The specifications of the above plates are 1200mm * 2400mm
