四川石化开发高密度聚乙烯拉丝料新品
四川石化在高密度聚乙烯装置上成功开发出新牌号拉丝料产品HF7750S,经检测该产品的拉伸屈服强度、拉伸断裂标称应变等各项性能指标均达到或超过国内同类拉丝料产品优等品指标。此次新牌号的开发为国内首次在HOSTALEL低压淤浆工艺中加入丙烯作为共聚单体,生产出拉丝料HF7750S,填补了此项技术的国内空白。
为使新产品能更好地满足市场需求,四川石化技术部门联合西南销售分公司在试生产前对下游市场进行了走访和调研,为新产品的成功开发奠定了坚实的基础。从6月16日开始,装置开始进行操作参数调整试生产,最终稳定各项产品指标,实现了乙烯+氢气+丙烯共聚技术在本装置上新的突破。据悉,拉丝料HF7750S产品具有高密度和窄摩尔质量分布特性,广泛应用于高拉伸强度单丝产品生产,也可作为其他产品的复配料,市场潜力巨大。此新产品不但丰富了四川石化化工产品牌号,为新产品的开发提供了宝贵经验,也为公司提高产品市场竞争力、提供新的盈利增长点提供了有力保障。
