本文介绍了褐煤蜡—石蜡系中温模料的试验研究情况。在褐煤蜡和石蜡系模料中加入低分子聚乙烯、松香或聚合松香组成三元或四元模料,其中褐煤蜡5%、低分子聚乙烯5%、聚合松香5%、石蜡85%的四元模料已在北京油咀油泵厂投入生产。文中介绍了这种模料的试验、生产验证和在生产中应用的情况及其回收方法。 This paper introduces the experimental research of montan wax-paraffin medium temperature mold. Low molecular weight polyethylene, rosin or polymerized rosin are added into the montan wax and paraffin mold materials to form a ternary or quaternary mold material, wherein montan wax is 5%, low molecular weight polyethylene is 5%, polymerized rosin is 5% and paraffin wax is 85% Four yuan model oil pump factory in Beijing has been put into production. This article describes the test of this material, production verification and application in the production of the situation and its recovery methods.
