１．展览的密度板：一般用的都是低 密度板和中密度板。密度板的加工工艺一般是松扬等原木加工成小块，然后粉碎成很细的粉末，加入石蜡胶等物质将粉末重新通过高温压制成板材，低 密度中密度板加工工艺差不太多，但是强度不一样中密度板的工艺过程需要有严格的参数控制，才能保证质量和强度以及甲醛等添加剂不超标，才能达到我国要求。

1. Density board for exhibition: low density board and medium density board are commonly used. Density board processing technology is generally Songyang log processed into small pieces, and then crushed into very fine powder, adding paraffin glue and other substances, the powder will be re pressed into plate through high temperature, low cost The processing technology of MDF is not too bad, but the strength is not the same. The process of MDF needs to have 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 requirements of our country.

２．防火板是密度板表面加了一层阻燃性的涂层起到耐燃的效果，厚度有0.6mm/0.8mm/1.0mm/1.2mm/1.5,比较薄的例如一张办公纸的厚度.其表面的颜色繁多.可按要求任意选则.其表面有光面和麻面可选.一般用于木质体表面,用专用胶水粘贴.相比油漆有,耐磨,阻然,施工方便.展览一般选择为08mm的厚度。

2. 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 0.6 mm / 0.8 mm / 1.0 mm / 1.2 mm / 1.5, and the thickness of a thin piece of office paper, for example. Its surface has many colors. It can be selected according to the requirements. Its surface has smooth surface and pitted surface. It is generally used on the surface of wood, and pasted with special glue, The construction is convenient. The thickness of the exhibition is generally 08mm.
              

３．展览用的夹板也称为多层板。国内一般称合板。例如三合板、五合板、九合板等。一般称夹板或厘板，例如：三厘板、五厘板、九厘板、十二厘板、15厘板、18厘板等。它是由二层结构组成，主要是表面的单板和夹芯的中板。单板是由原木蒸煮旋切而成。厚度理论上在0.4~0.5mm之间。中板也是由原木蒸煮旋切而成的厚皮。中板依制造的夹板厚度不一，而厚度相应随着变化。在展览中用于做强面。

3. The plywood for exhibition is also called multilayer board. It is generally called plywood in China. For example, plywood, plywood, plywood, etc. It is commonly referred to as splint or plywood in the world, such as three, five, nine, twelve, 15, 18 and so on. It is composed of a two-layer structure, mainly a single board on the surface and a sandwich medium board. Veneer is made by log cooking and rotary cutting. Theoretically, the thickness is between 0.4 and 0.5mm. The medium board is also a thick skin made by log cooking and rotary cutting. The thickness of the middle plate varies according to the thickness of the plywood. It is used to strengthen the surface in the exhibition.

４．展览用的刨花板可想而知，用的主要材料就是刨花。刨花稍做加工,加入一些添加剂压制成型，工艺比较简单，原材料也便宜，是密度板的廉价替代品。强度等性能都比密度板差很多。存在容易破损等问题。但是表面贴膜后，如果不看断面，是看不出来有什么问题的。

4. It can be imagined that the main material used in the exhibition is particleboard. It is a cheap substitute for density board because of its simple process and cheap raw materials. Strength and other properties are much worse than density board. It is easy to be damaged. But after the surface is coated, if you don't look at the section, you can't see what the problem is.

另外还有一种叫防潮板，实际是在密度板中添加了防潮剂，截面呈现深绿色，和密度板类似。

In addition, there is also a kind of moisture-proof board, which is actually added moisture-proof agent in the density board. The cross section is dark green, similar to the density board.
