The performance advantage of polyurethane cold storage insulation board creates a new trend of building materials After determining the type of polyether according to the initiator, hydroxyl value and viscosity, the polyether is selected to have a low potassium ion content. It is recommended to select foam stabilizers with strong emulsifying capacity. It is mainly to control the size of the cell, maintain the stability of the cell, and prevent the collapse of the cell. The silicone ketone foam stabilizer has a good effect on this, and its dosage can be adjusted in the range of 1.5~2.5 (mass fraction), which has a direct impact on the density, strength and other physical properties of rigid polyurethane foam. The foaming agent can not only adjust and control the density and properties of the foam product. To strengthen the power supply of Li Zhou Power Supply Bureau

The foaming agent can not only adjust and control the density and properties of the foam product. In order to strengthen the management of safe use of electricity in each movable plank house in the power supply area of Lizhou Power Supply Bureau, the occurrence of "personal electric shock casualty accidents and electrical fire accidents" should be avoided. The products of our polyurethane insulation board factory have been tested by relevant departments, and there is no problem with product quality. As an excellent fireproof material.
Polyurethane cold storage insulation board is now very common plate. Seeing the use of this kind of board can be said to be a "boom" in China, and it can be seen in almost different cities. What is its characteristic?
The sealing and waterproof of polyurethane cold storage insulation board is very prominent, because the closed cell rate of this board can reach 100, and the closed cell rate of rigid foam is as high as 90%. Excellent waterproofness and sealing.
In addition, the sound insulation performance of polyurethane insulation board is equivalent, because after several years of improvement, this board is produced and processed by high-tech technology. The closed-cell structure can be said to be due to ordinary building materials and boards, so the sound insulation effect is better. It can provide users with a quiet, healthy and comfortable indoor home environment, and its safety can also be guaranteed, and it will not release harmful toxic gases for the furniture environment.
These factors are related to the adhesion between the foam and the cavity walls and the dimensional stability of the foam. Flame retardants can improve the flame retardancy of the foam, but they will destroy the foam during the foaming process. Under the premise of improving the flame retardant effect, the performance and dimensional stability of the foam can be guaranteed. Polyurethane composite board has good wear resistance and corrosion resistance, and shows excellent performance in building heat preservation, heat insulation, sound absorption and noise reduction. Therefore, how to choose a better polyurethane composite board is very important. The products of our polyurethane insulation board factory have been tested by relevant departments, and there is no problem with product quality. As an excellent fireproof material. All passed the fixed fire extinguishing system and fire-resistant components quality inspection center. The combustion level has passed the standard, and many can better deal with some problems in the environment. The polyurethane used in this product has a high ignition point. Then some other chemicals are added in the production process.
