| 冷库保温材料的保温性能： Insulation of cold storage materials: 用于冷库方面的聚氨酯保温材料第一要求便是保温性能，而保温性能的好坏在真正投入使用前是无法用肉眼观察出来的，到了观察出耗电量高低差别时已经为时过晚。该公司通过大量的实验检测，在选材方面进行严格控制，以期达到这一目的： Used for cold storage pu heat preservation material of the first requirement is the thermal insulation performance, the heat preservation performance is good or bad before put into use real cannot be observed with the naked eye, to observe the difference in power consumption has been too late. The company, through a large number of experimental tests, strictly controls the selection of materials in order to achieve this goal: ①使用结构性胺醚，降低导热系数，提升保温效果； Use structural amine ether to reduce heat conductivity and improve insulation. ②各种原料以及配方中尽量将含水量降低，避免水发泡造成保温性能劣化； To reduce moisture content in all kinds of raw materials and formulas and avoid the degradation of heat preservation by water foaming. ③主体材料聚醚：选用经过严格后处理的大厂的产品（如金陵石化公司等），与小厂不经后处理的聚醚相比，其泡沫泡孔均匀程度高、泡孔壁较薄，保温性能明显优于厚壁大孔的普通泡沫； Material selection polyether: (3) the main body through strict processing of metal products (e.g., jinling petrochemical corporation, etc.), compared with the small factory without post-processing of polyether, the bubble bubble pore uniformity degree is high, bubble hole wall is thinner, heat preservation performance are better than those of ordinary bubble of thick wall or big hole; |
