大庆石化公司塑料厂60kt/a线型低密度聚乙烯(LLDPE)装置采用低压气相法流化床生产工艺,以乙烯为原料,1-丁烯(或己烯-1)为共聚单体,氢气为相对分子质量调节剂,生产LLDPE树脂[1,2]。为提高线型聚乙烯产品的性能,有效利用己烯-1单体,采用己烯-1为共聚单体,生产专用树脂HF-7042。1产品配方的确定在LLDPE中加入无机开口剂吹膜后,无机物会在LLDPE薄膜表面形成凸凹面,而降低薄膜间的粘合力,起
Daqing Petrochemical Company Plastic Factory 60kt / a linear low density polyethylene (LLDPE) device using low pressure gas phase fluidized bed production process, ethylene as raw material, 1-butene (or hexene-1) as comonomer, hydrogen For the relative molecular mass regulator, LLDPE resin production [1,2]. To improve the performance of linear polyethylene products, the effective use of hexene-1 monomer, the use of hexene-1 as a comonomer, the production of special resin HF-7042.1 product formulations to determine the addition of inorganic open-mouth blown film in the LLDPE After the inorganic material will be formed in the LLDPE film surface convex surface, and reduce the adhesion between the film,
