中国石化企业柴油抗磨剂标准的制定和修订解读

FORMULATION AND REVISION OF SINOPEC ENTERPRISE STANDARDS FOR DIESEL ANTI-WEAR ADDITIVES

对中国石化企业柴油抗磨剂标准的制定和历次修订过程进行了解读。修订后的标准按组成分为脂肪酸型和脂肪酸酯型两类,脂肪酸型抗磨剂中浊点和饱和脂肪酸含量指标是产品质量控制的关键指标,控制浊点不大于-8℃、饱和脂肪酸质量分数不超过2.5%;脂肪酸酯型抗磨剂中饱和脂肪酸含量和金属含量是关键指标,饱和脂肪酸质量分数不超过2.5%、金属质量分数不大于50g/μg。指出了标准的制定和修订对控制柴油抗磨剂产品质量的作用。

The successive formulations and revisions for SINOPEC group diesel anti-wear additive standards were introduced.The revised standards were divided into two different categories of fatty acid type and fatty acid ester type.Cloud point and saturated fatty acid content are two crucial items in fatty acid type lubricity additive and must be maintained below-8℃and 2.5%respectively.Saturated fatty acid content and metal element content are two important items in fatty acid ester type lubricity additive.They are limited not to exceed 2.5%and 50μg/g,respectively.The specification played an important role in controlling the quality of diesel fuel lubricity additives.
