《GB/T 4611-2008通用型聚氯乙烯树脂“鱼眼”的测定方法》由TC15(全国塑料标准化技术委员会)归口,TC15SC7(全国塑料标准化技术委员会聚氯乙烯树脂产品分会)执行,主管部门为中国石油和化学工业联合会。
本标准代替GB/T4611―1993《通用型聚氯乙烯树脂“鱼眼”的测试方法》。本标准规定了以压延成片法测定通用型聚氯乙烯树脂(PVC)鱼眼数的方法。本标准适用于通用型聚氯乙烯树脂鱼眼数的测定。 本标准与GB/T4611―1993的主要差异为:
―――增加了警示语;
―――增加了“术语和定义”一章(本版第3章);
―――修改了材料的要求(1993年版第3章,本版第4章);
―――调整了二辊炼塑机的速比(1993年版4.1,本版5.1);
―――删除了对测温仪器类型的规定(1993年版4.2,本版5.2);
―――表1和表2中增加了SG9(黏数小于73)这一型号树脂,但未规定其试料的制备配方和制片温
度,由供需双方协商确定(1993年版表1及表2,本版表1及表2);
―――调整了制备试料中加入材料的顺序(1993年版5.3,本版6.3.1);
―――删除了辊筒表面风速的要求(1993年版5.3.2,本版6.3.2);
―――调整了检查试片厚度的时间(1993年版5.3.5,本版6.3.5);
―――增加了“试验报告”一章(本版第8章)。


Scope
