冷库库门是防止跑冷节约能耗的关键性设备。过去冷库库门一般都只是按设计图纸委托建筑部门或由使用单位自行制作,难以符合标准化、系列化的要求,主要的缺点是隔热性能不理想,牢度比较差。针对这个情况,杭州肉类联合加工厂从1984年开始试制PAPI—J型冷库库门。其主要改进是门的隔热层选用硬质聚氨脂,并采用现发泡灌注工艺。这种库门属第三代产品,较之过去用软木
Cold storage door is to prevent running cold to save energy consumption of the key equipment. In the past, cold storage doors were generally only commissioned by the design drawings or the construction sector by the use of self-production units, it is difficult to meet the standardization, serialization requirements, the main drawback is the insulation is not ideal, poor fastness. In response to this situation, Hangzhou meat processing plant trial since 1984 PAPI-J-type cold storage doors. The main improvement is the use of rigid polyurethane door insulation, and the use of foam filling process. This library belongs to the third generation of products, compared with the past with cork
