[0002] In the production process of polyurethane board, the quality and purity of raw materials play a crucial role in the performance of the final product. The production raw materials of polyurethane board usually contain multiple components, such as polyols, isocyanate and various additives.
[0003] During the storage, transportation and early processing of raw materials, some problems are inevitable, which will affect the subsequent production. On the one hand, the raw materials may appear to be agglomerated. For example, some additives are prone to agglomeration after being damp or stored for a long time, and polyols may form agglomerates due to temperature changes and other factors. If these agglomerated or agglomerated raw materials are directly put into production, it will lead to uneven mixing, and thus the chemical structure of the polyurethane board will be uneven, which will seriously affect its strength, thermal insulation performance and other key indicators. On the other hand, impurities are often mixed in the raw materials. These impurities may be dust, sand mixed in the transportation process, or unqualified particles left over from the production process of raw materials.
