随着我国社会主义建设的飞跃发展,石油、化工、化肥、农药、印染、造纸等部门特别需要防腐耐温的阀门,但目前由于我国不锈钢等材料来源困难,造价高,且寿命不长,大部分靠进口,而衬胶阀门不耐高温、易老化、防腐蚀不理想。因此,防腐蚀阀门长期短缺,不能满足化工等部门的需要,必须在阀门的防腐蚀材料上寻找新的途径。湖南长沙阀门厂与省塑料研究所协作
With the rapid development of socialist construction in our country, petroleum, chemical, fertilizer, pesticide, printing and dyeing, papermaking and other departments especially need anti-corrosion and temperature-resistant valves. However, due to the difficulty of source materials such as stainless steel in our country, high cost and short service life, Part of the import, while rubber lining valve is not heat-resistant, easy to aging, anti-corrosion is not satisfactory. Therefore, the long-term shortage of anti-corrosion valves, chemical and other departments can not meet the needs of the valve must be on the anti-corrosion materials to find new ways.
