【摘要】 研究了防冻液中多金属在高温下使用的缓蚀剂。针对市面上使用的防冻液许多都含有亚硝酸盐、铬酸盐等有毒成份及昂贵的铂系、钨系成份,采用无毒低价的组分为防冻液主要成份,保护环境及人体安全,达到防腐、防冻、防沸、防泡、防垢的功能。研究了主要缓蚀剂硅酸钠;硼砂;苯甲酸钠的最佳配比关系。实验结果表明,各项技术指标均达到石化行业标准SH/T0521-1999的规定。更多还原

【Abstract】 Many of anti-freezing fluids in the market contain such poisonous component as nitrite,chromate and expensive component of platinum and tungsten system.This program uses some non-poisonous and cheap components as the main components of anti-freezing fluid,which are environment friendly,safe,with the function of anti-corrosion,anti-freezing,anti-boiling,anti-foaming,anti-scale,etc.This paper discusses the mixing proportion among sodium silicate,borax,sodium benzoate.It is proved that all the technical indexes are in conformity with SH/T0521-1999.更多还原
