基于冶金行业设备安装材料工艺的改进

基于冶金行业设备安装材料应用广泛的PP材料,进行优化改进,采用的是辐照交联的方法,通过实验得出辐照交联密度是0.22 g/cm3,实验材料的用量是0.96%的敏化剂是优化比较好的情况。此时PP泡沫材料的表面密度是0.28 g/cm3,抗拉强度为6.19 MPa。实现了气泡孔隙结构形式会发生较大变化,达到了实现冶金需要的结构归正、均匀的EPP材料目的。

Modification of PP Materials as Equipment Installation Materials in Metallurgy Industry

PP materials are widely used as equipment installation materials in metallurgy industry. In this paper, PP materials were modified by irradiation cross-linking method. The result showed that when the irradiation crosslinking density was 0.22 g/cm3 and the dosage of sensitizer was 0.96%, the surface density of modified PP foam material was 0.28 g/cm3, and the tensile strength was 6.19 MPa. Great change of the pore structure of bubbles was realized, and PP materials with excellent performance were obtained.
