Polyamide by epsilon - polymerization of caprolactam and become a kind of polymer material, because the epsilon - ring opening polymerization of caprolactam is a complex process of reversible reaction equilibrium after product containing a certain amount of monomer and low molecular cyclic oligomer. For injection machine Que producing needle used in the preparation of the polyamide resin, because the caprolactam in polyamide on the human body can irritate eyes and central nervous, especially
Xiang ying analysis technology co., LTD adopts XiangyingGC7990plus gas chromatography determination of residues of caprolactam in polyamide resin, satisfactory results
聚酰胺是由ε-己内酰胺聚合而成的一类高分子物质,由于ε-己内酰胺的开环聚合是一个复杂的可逆过程,反应平衡后的产物含有一定量的单体和低分子环状齐聚物。注射用辛芍冻干粉针的制备工艺中使用了聚酰胺树脂,由于聚酰胺中的己内酰胺对人体的眼睛和神经有刺激作用,特别是 滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus气相色谱法测定聚酰胺树脂中己内酰胺残留量,结果满意
