The preparation of low temperature environment and the low-temperature storage of material are widely used in, because the medical refrigerator cabinet internal-external temperature difference of low temperature is larger, therefore cabinet
Interior Temperature Distribution is generally uneven to have a strong impact on the quality and safety for preserving thing, simultaneously because polyurethane foam be chronically at compared with
Under low temperature conditions, there is higher requirement to Low-Temperature Size stability, compressive strength and the thermal conductivity factor of polyurethane foam, and
Common cyclopentane type combined polyether emphasis considers foaming agent security, while the foam density prepared is higher and size of foam is steady
Qualitative and heat insulating ability is poor, and work contraction distortion amount relatively large cause froth bed of the foam with the time under the conditions of prolonged cold
Thickness will be gradually reduced, and the performance such as thermal conductivity factor and compression strength of foam will all decrease, and polyurethane foam insulation is heat-insulated
Performance reduction is obvious, largely effects on heat insulation effect and adds energy consumption, causes the wasting of resources.
