How to improve the insulation effect of polyurethane cold storage insulation materials:
1. Use structural amine ether to reduce thermal conductivity and improve thermal insulation effect;
2. The water content should be reduced as much as possible in various raw materials and formulations to avoid deterioration of thermal insulation performance caused by water foaming;
3, the main material polyether; the product after strict post-treatment, compared with the polyether without post-treatment, the foam cell has a high degree of uniformity, the cell wall is thin, the thermal insulation performance is significantly better than the rear wall macropores Ordinary foam
4. The use of high-efficiency and odorless amine catalysts can effectively adjust the balance of the foaming-gel reaction, so that the skin of the spray booth is thinner, which is beneficial to the performance of the cold storage insulation material;
5. Do not use ordinary polyester polyols.
