前言稳定剂是生产聚丙烯必不可少的主要助剂,但是由于稳定剂自身的因素会从不同方面、不同程度的影响聚丙烯的产品质量。自2002年以来,聚丙烯装置生产的聚丙烯产品随时有黄料出现,严重影响产品质量,针对聚丙烯产品出现黄料较多的问题,年初公司引进了复合抗氧剂9301、PW-9225,但由于检测手段不完善,不能看出复合抗氧剂的直接效果。 Preface Stabilizers are essential additives for the production of polypropylene, but because of their own factors, the quality of polypropylene products can be affected in varying degrees and to varying degrees. Since 2002, polypropylene products produced by polypropylene plant appear yellow material at any time, seriously affecting the quality of products. In the beginning of the year, the company introduced compound antioxidants 9301, PW-9225, However, due to imperfect detection means, can not see the direct effect of composite antioxidants.
