Briefly introduce how the foam packaging box is shaped
The shaping of the packaging box is mainly made by extruding raw materials. The extrusion process is a very important step in the processing of pressure-sensitive adhesives. The raw material of the foam packaging box will be subjected to the action of water vapor when it is squeezed, so that the raw material becomes foam paper. Because the foam paper particles are easier to deform, the foam paper can be molded into products of different shapes according to the different needs of users.

What are the requirements for foam board in operation?
Our foam board is also known as foam insulation board. It is made of expandable polystyrene beads containing volatile liquid foaming agent. It is pre-heated and heated in a mold to form a white object. The foam board has fine closed cells. The structural characteristics of the foam board are mainly used for building walls, roof insulation, composite board insulation and other fields. So what are the requirements for foam board operations?

Briefly introduce the performance characteristics of polystyrene insulation board
1. Excellent thermal insulation performance
Polystyrene insulation board is mainly made of polystyrene, and polystyrene is a low thermal conductivity material, which is then extruded to form a compact honeycomb structure, which effectively prevents heat conduction. The thermal conductivity of polystyrene board is 0.028/mk, it has the characteristics of high thermal resistance and low linear expansion rate. The thermal conductivity is far lower than other insulation materials. At the same time, the board is light and cheap, and has a stable chemical structure and physical structure, which can ensure the insulation performance of this material Durable and stable, so it is one of the best insulation materials at present.
2. Anti-corrosion and durable performance
Polystyrene board has excellent anti-corrosion, anti-aging properties, heat preservation, and its service life can reach 30-40 years.
3. High-strength compressive performance
The EPS board has extremely high compressive strength, even if the blisters remain unchanged for a long time, it has a large bearing capacity and good impact resistance;
4. Superior water resistance and moisture resistance
The EPS board has a tight closed-cell structure, the polystyrene molecular structure itself does not absorb water, and there are no gaps on the front and back of the board, so the water absorption rate is extremely low, and the moisture and penetration resistance are excellent.
5. Light weight, high hardness, convenient construction and low cost
The fully closed-cell foamed structure of the EPS board is lightweight, and the uniform honeycomb structure makes it high in hardness, so it is not easy to be damaged, easy to handle, easy to install, easy to cut, and it will not affect the bearing capacity of the structure when used as roof insulation.
6. High-quality environmentally friendly
EPS board is not easy to decompose and mildew, no harmful substances volatilize, chemical properties are stable, and it is a high-quality environmentally friendly product.
Polystyrene insulation board is a kind of insulation material with excellent properties such as high compression resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, aging resistance, and low thermal conductivity. It is currently commonly used in the construction industry and is a high-quality insulation material. ,Insulation Materials.
