Jiangmen Foam Factory shares the advantages and recycling methods of foam

　Foam is a very familiar word. There are many foam products in life, such as disposable lunch boxes and foam boxes used in the transportation of some fruits and vegetables. In addition, it is also used in construction. Jiangmen foam factories indicate that this is because it has the following advantages:

　　1. It can protect the main structure of the building and extend the life of the building 的寿命。

　　2. It effectively eliminates the internal insulation used in the past "thermal bridges," which is difficult to avoid. The external insulation layer is placed outside the structure, reducing the stress caused by structural deformation due to temperature changes, reducing the erosion of harmful substances in the air, effectively preventing the generation of thermal bridges, and avoiding condensation.

　　3. It can improve the dampness of the walls. Generally, a vapor insulation layer is needed for internal insulation, and foam is used for external insulation. The temperature permeability of the external insulation material is far stronger than that of the main structure, increasing the temperature of the entire wall structure, and further enhancing the insulation performance of the wall.

　　4. It is conducive to the stability of indoor temperature. Because the structural layer with high heat storage capacity is located inside the wall, it is more conducive to the stability of the room temperature loss.

　　5. Foam can also increase the usable area of the house and avoid damage to the insulation layer during secondary renovation.

6. It also has a very good shock absorption effect. During transportation, there will inevitably be squeezing and bumps. However, with foam as the packaging material, these are not problems. Foam can use its own compression to buffer some bumps and vibrations caused by external forces.

　　There are more and more Jiangmen foam factories on the market now. When purchasing foam, users must purchase it from a regular Jiangmen foam factory.

　　The main methods of foam recycling are: volume reduction and granulation; crushing and use as various filling materials; pyrolysis oil or styrene recovery, etc. Everyone knows that foam has many advantages when used. In fact, recycling after use can also bring great help to people. The following points are the main methods of recycling.

　　1. After volume reduction and granulation, it can be melt-extruded and granulated to produce recycled granules. Due to its huge volume, it occupies a large space during transportation, which is inconvenient for transportation. Therefore, volume reduction is the first step in recycling. These methods include mechanical methods, solvent methods, and heating methods.

　　2. The foam is crushed and used as a filler. Jiangmen foam factories indicate that the crushed foam can be used as a filler to make various products. It can be re-molded into foam products, or made into composite board products, gypsum sandwich bricks, and used as asphalt enhancers, etc.

　　3. Pyrolysis to produce oil or recover styrene. Waste foam is pre-treated, heat-treated, volume-reduced, and catalytically cracked to distill styrene.

　　4. After crushing waste foam products, appropriate solvents can be added to make coatings.
