聚氨酯保温管原料的贮存方式
Storage of Polyurethane Thermal Insulation Pipe Material
硬质聚氨酯组合料分爲异氰酸酯和组合聚醚两个组份:俗称黑料和白料。两者按比例搅拌混合后发作聚合反响,生成具有闭孔构造的聚氨酯硬质泡沫塑料,是一种理想的无机质高温隔热资料,具有导热系数小,节能防震,顺应性强,既可预制成型,也可现场喷涂式浇注成型、普遍使用于炼油厂、化工厂、乙烯化工、冷库、单制冷空调、冰箱和修建业保温隔热。随着在修建节能范畴的推行,聚氨脂发泡保温体系以其良好的保温功能和施工迅速,功能牢靠等特点已在保温范畴大规模使用。 聚氨酯组合聚醚和异氰酸酯的贮存与平安操作
Rigid polyurethane composite material is divided into two components: isocyanate and polyether: commonly known as black and white. The rigid polyurethane foam with closed-cell structure is an ideal inorganic material for high temperature insulation. It has low thermal conductivity, energy-saving, shock-proof and strong compliance. It can be pre-fabricated or sprayed on-site pouring moulding. It is widely used in refineries, chemical plants, ethylene chemical industry, cold storage, single refrigeration and air-conditioning, etc. Refrigerator and construction industry heat preservation and insulation. With the implementation of energy-saving construction, polyurethane foam insulation system has been widely used in the field of thermal insulation because of its good thermal insulation function, rapid construction and reliable function. Storage and Safe Operation of Polyurethane Composite Polyether and Isocyanate
一、贮存 异氰酸酯(俗称黑料)与组合聚醚(俗称白料)的贮存必需是在密封的容器内,隔绝空气、避免吸潮。 异氰酸酯与组合聚醚料桶不应在阳光下暴晒,必需远离热源,放置凉枯燥处,料桶假如直立放置时,桶盖上不得积水!假如整桶料不能一次用完,就必需在每次运用后立刻盖紧桶盖,避免水汽、杂质进入桶内而影响质量。
1. Storage of isocyanate (commonly known as black material) and composite polyether (commonly known as white material) must be in a sealed container to isolate air and avoid moisture absorption. Isocyanate and composite polyether barrels should not be exposed to sunlight, they must be far away from heat sources and placed in cool and dry places. If the barrel is placed upright, the barrel cover should not accumulate water. If the whole barrel material can not be used up at once, the barrel cover must be tightened immediately after each use to avoid water vapor and impurities entering the barrel and affecting the quality.

假如运用两个以上牌号组合聚醚时,应分牌号堆放,并有分明标志。参加普通阻燃剂的组合聚醚寄存工夫不应太长,必需当天配制当天运用,否则易形成蜕变影响发泡质量。 聚氨酯直埋保温管近期销量走势 随着各类不同的直埋保温管开端呈现在市场中当前,关于这样的一种技术的创新还是具有很大的作用的。怎样样让这种适用性表现出来恩?关键就是在于社会效益和经济效益,由于各种不同的保温效果也是在这个进程中可以更好的表现出来的。因而作爲供热节能进程中的一种无效措施,进入到市场中当前,逐步的关于这样的供热管道也是具有了新的终点。
If two or more brands are used to combine polyethers, they should be stacked separately and clearly marked. The storage time of the combined polyether with common flame retardant should not be too long. It must be used on the same day when it is prepared, otherwise it will easily degenerate and affect the foaming quality. The recent sales trend of polyurethane direct-buried insulating pipes has appeared in the market with the beginning of various types of direct-buried insulating pipes. The innovation of such a technology still plays a very important role. How to show this applicability? The key lies in the social and economic benefits, because different thermal insulation effects can be better displayed in this process. Therefore, as an ineffective measure in the process of heating and energy saving, entering the market at present, gradually on such heating pipeline also has a new end point.
聚氨酯直埋保温管近期销量走势 针对直埋保温管的劣势,次要就是在于需求创新,更好的关于这样的功能、质量、以及相关的劣势条件停止不时的开展,这样在运用进程中,才干够起到更好的效果,也是进入到中国市场中当前,逐步被认可的一种资料。 更好的让直埋保温管进入到很多修建行业中,那麼这样的一项技术还是需求不时的完善和开展,更好的表现这样的用处。
The recent sales trend of polyurethane direct-buried insulating pipes is aimed at the disadvantage of direct-buried insulating pipes. Secondly, the demand innovation is needed. Better performance, quality and related disadvantage conditions are stopped from time to time. In this way, in the process of application, it can play a better effect, and it is also a kind of information that is gradually recognized in the Chinese market. Better let directly buried insulation pipe into many construction industries, then such a technology or need to be improved and carried out from time to time, better performance of such use.
