由陕西省富平防腐工程公司研试成功的单体液压支柱喷涂改性环氧粉末涂料的防腐新工艺,经过在铜川矿务局陈家山煤矿、下石节煤矿工业性试验和试用(共喷涂修复DZ-22型单体液压支柱4813根,在七个高档普采工作面试用),效果良好,陕西省煤炭工业厅于1989年1月30日召开了技术鉴定会,通过了鉴定。这种防腐涂层的材料是人工合成的高分子聚合物,是以粉状环氧树脂为基本原料,
Fuping anti-corrosion engineering company in Shaanxi Province, the successful pilot study of single hydraulic proppant modified epoxy powder coating anti-corrosion process, after the Tongchuan Mining Bureau Chen Jiashan coal mine, Shilishi coal mine industrial test and trial (a total of spray repair DZ-22-type single hydraulic prop 4813, seven high-grade common mining face trial), the effect is good, the Shaanxi Provincial Coal Industry Office on January 30, 1989 held a technical appraisal meeting, passed the appraisal. This anti-corrosion coating material is synthetic polymer, based on powdery epoxy resin as the basic raw material,
