摘要
本文介绍了用测定反应物 pH 变化控制高碱性环烷酸钙“钙化”终点的方法及用轻质碳酸钙作助滤剂的过滤工艺。并以高碱性环烷酸钙为主剂,试制成功30号 QC 级汽油机油和 CZA10号船用气缸油。
This paper presents the method of controlling the calcification end pointof high basic calcium naphthenate by measuring the variation of pH valueof reactants as well as the filtration process with calcium carbonate as filteraid.These two technologies are important ensuring the product quality andreducing environmental pollution.No.30 QC motor oil and CZA No.10 marinecylinder oil are successfully formulated,evaluated and tested in actual appli-cation.
