Engineering technical parameters of pharmaceutical low-temperature cold storage within 100 cubic meters:

1. Temperature range of pharmaceutical cold storage (℃):
Low-temperature insulation storage: -20℃～-50℃ to store plasma, biological materials, vaccines, reagents, etc.
Ultra-low temperature storage: -50℃～-100℃ can be used to store placenta, semen, stem cells, plasma, bone marrow, biological samples, etc.

2. Performance and parameters of polyurethane insulation board

Thermal insulation performance of cold storage insulation materials:
The requirement of polyurethane insulation materials is thermal insulation performance, and the quality of thermal insulation performance cannot be observed with the naked eye before it is put into use. By the time the difference in power consumption is observed, it is too late. The company has carried out a large number of experimental tests and strict control in material selection in order to achieve this goal:
Use structural amine ether to reduce thermal conductivity and improve thermal insulation effect;
Try to reduce the water content in various raw materials and formulas to avoid water foaming and deterioration of thermal insulation performance;
Main material polyether: Select products from large factories that have undergone strict post-treatment (such as Jinling Petrochemical Company, etc.). Compared with polyethers from small factories that have not undergone post-treatment, their foam pores are highly uniform and the pore walls are thinner. The thermal insulation performance is significantly better than that of ordinary foams with thick walls and large pores. The use of effective odorless amine catalysts effectively adjusts the balance of foaming-gel reaction, making the surface between the spray layers thinner, which is conducive to the performance of cold storage insulation materials.
Ordinary polyamine polyols are not used. These control measures have achieved quite good results. In a comparison of several cold storages at a customer in Jining, the cold storage using its white material consumes significantly less electricity than the cold storage using white material from other manufacturers.
