Polyurethane spraying machine hard foam combination polyether is one of the important materials of polyurethane spraying machine rigid foam, also known as white material, and polymer MDI is collectively known as the material. The two are stirred after mixing in proportion. The polymerization reaction produces a rigid foam plastic of polyurethane spraying machine with a self-contained closed-cell structure, which is an ideal material for low-temperature thermal insulation of organic materials. It has the characteristics of small thermal conductivity, energy saving, shock resistance, and strong compliance. What are the meticulous matters during storage and use? The following is shared by everyone of the polyurethane sprayer material manufacturers.
The white material of the polyurethane spraying machine should be packed in a dry and clean special galvanized iron bucket, sealed and stored in a dry, cool, ventilated place, waterproof, sun-proof and heat-proof; storage environment temperature: 15 ~ 25 ℃.
1.It is necessary to adjust the material temperature in the appropriate range when foaming is used to ensure that the system has appropriate response performance and activity;
2.When foaming, it should be cruel to confirm the ratio of white material to black material according to the application clarification request to ensure that the process performance of the system and the fundamental properties of the foam are not affected;
3.Do not allow the data to come into contact with moisture.Please be careful and properly ventilated at the consumption site.
After that, it should be more careful. When the polyurethane spraying machine stops storing the materials, the isocyanate and the combined polyether bucket should not be exposed to the sun. It must be separated from the heat source and placed in a cool and dry place. Water cannot be accumulated on the top. Assuming that the entire barrel cannot be used up at once, it must be tightly closed immediately after each use to prevent water vapor and impurities from entering the barrel and affecting the quality.
