      利用炭黑含量测试仪检测塑料的产品质量
      2019-03-27 14:53:59

      近年来,聚乙烯材料广泛应用于排污、油田、化工、通讯、给水、农业灌溉、燃气输送、等领域。无添加剂的聚乙烯耐气候老化和?#23637;?#26333;晒性能很差,因而?#23548;?#20351;用时都会添加炭黑。炭黑能使材料具有足够的抗紫外老化能力,当炭黑含量为2.0%~3.0%时可确保?#34892;?#22320;防止紫外线的影响。由于炭黑含量大小对聚乙烯管材具有重要的影响,许多标准都对聚乙烯中的炭黑含量作了规定,为了研发生产和销售的目的,炭黑含量是聚乙烯管材必须进行检测的指标。

      DZ3500炭黑含量测试仪产品介绍:

      该仪器适用于聚乙烯、聚丙烯、聚丁烯塑料中炭黑含量的测定。

      炭黑的测试是通过试样在氮气保护下,高温分解后的重量分析得到的。

      该仪器具有使用方便,操作简单,工作可靠,测量准确,自动控温等优点。

      炭黑含量在产品性能中是一个重要的技术指标,含量的多少对材料的硬度、弹性、耐磨、绝缘性?#21152;?#19968;定的影响。

      符合标准:ISO 6964,GB/T 13021,IEC 60811-4-1,GB/T 2951.41,JTG E50 T1165,

      ASTM D1603-2012,CJ/T 125—2000,GB/T2951.41-2008

      电缆和光缆绝缘和护套材料通用试验方法等相关测试标准
