己內酰胺
特征:
己內酰胺在液態為無色,在固態下為白色(片狀),手觸有潤滑感,并有特殊的氣味,具有吸濕性,易溶于水和苯等,受熱起聚合反應,遇火能燃燒。熔點68℃—69℃,760mmHg下沸點270℃,85℃下密度1010kg/m3。
用途:
主要用于生產聚酰胺—6(尼龍6)。聚酰胺-6可加工為:
——民用絲 可制作民用紡絲品,如衣物、裝飾物、地毯、毛毯等;
——工業絲 可制作輪胎簾子布、帆布、運輸帶、漁網、繩索、降落上等。
——工程塑料 可制作機械、汽車、電器、電子產品的零部件和元器件,工程用管、棒、板帶材等。
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.
包裝:用兩層牛皮紙夾一層聚丙烯編織袋,內襯一層高壓聚乙烯薄膜袋包裝,每袋凈重25kg。
儲運:存于干燥、清潔庫房中,不得露天存放和受潮。隔絕熱源和火種,不可與易潮解物品、氧化劑、酸、堿物品共儲混運。搬運時輕裝輕卸,防止破壞包裝。
