己内酰胺
特征:
己内酰胺在液态为无色,在固态下为白色(片状),手触有润滑感,并有特殊的气味,具有吸湿性,易溶于水和苯等,受热起聚合反应,遇火能燃烧。熔点68℃—69℃,760mmHg下沸点270℃,85℃下密度1010kg/m3。
用途:
主要用于生产聚酰胺—6(尼龙6)。聚酰胺-6可加工为:
——民用丝 可制作民用纺丝品,如衣物、装饰物、地毯、毛毯等;
——工业丝 可制作轮胎帘子布、帆布、运输带、渔网、绳索、降落上等。
——工程塑料 可制作机械、汽车、电器、电子产品的零部件和元器件,工程用管、棒、板带材等。
Features:
Caprolactam is colorless in liquid state and white in solid(flake), with a slippy touch and special smell. It is hydroscopic, and apt to dissolve in water and benzene, when it is heated, a polymerization will take place and it will combust in fire.
Melting point: 68~69℃
Boiling point: 270℃(at760mmHg)
DENSITY:1010kg/m3(at 85℃)
Application:
Caprolactamis largely used in producing nylon 6 which can be further processed into:
Textile yarn: for making textile products, such as clothing, carpet, blanket and woven decoration materials etc.
Engineering plastics: for making engingeering pipes bars, plates, and tapes etc.
包装:用两层牛皮纸夹一层聚丙烯编织袋,内衬一层高压聚乙烯薄膜袋包装,每袋净重25kg。
储运:存于干燥、清洁库房中,不得露天存放和受潮。隔绝热源和火种,不可与易潮解物品、氧化剂、酸、碱物品共储混运。搬运时轻装轻卸,防止破坏包装。
