Medical refrigerated box requirements can be a long time to keep low temperature, dry, but also have better shock resistance and anti-extrusion performance, according to the above requirements, select the best material.
(1) the production of cold storage box shell, should be used
Cotton Foam Plastic Hardboard
(2) cold storage box cooling filler material, should be used
Crushed ice cubes low temperature brine foam dry ice
(3) cold box inside the shell close to the liner, should be used
Soft paper velvet foam leather
The lining must be a poor conductor of heat and must be damped. Foam is more appropriate.
Cooling filler can only choose dry ice. Crushed ice does not meet the "dry, earthquake" requirements; low temperature salt water does not meet the "dry" requirements; foam is nonsense.
Hard plastic plate, dry ice, foam shell requirements anti-extrusion, only hard plastic plate to meet the requirements.
