一二二厂经过近六年的努力,现已取得砂毡、砂毡弹性抛光轮和砂毡生产线三项科技成果,最近通过了技术鉴定。砂毡研制成功并投产使用,填补了我国弹性抛光工具的一项空白,为民品开发增添了光彩。经过全国十个省市,上百家工厂试用证明,砂毡用于装饰抛光(如对表带、洗衣机上盖、大型电气柜、各种家具电器、各种标牌、度盘拉丝等表面抛光)、精度抛光(如对柴油机 After nearly six years of efforts, the No.12 and No.2 mills have achieved three scientific and technological achievements in the production of sand felt, sand felt elastic polishing wheel and sand felt production line, and recently passed the technical appraisal. The sand blanket was successfully developed and put into use, filling a gap in our country’s elastic polishing tools and adding luster to the development of civilian products. Through 10 provinces and cities across the country, hundreds of factories have proved that the sand felt is used for decorative polishing (such as polishing the surface of the watch band, washing machine cover, large electrical cabinet, various furniture appliances, various signs, dial drawing, etc.) , precision polishing (such as for diesel engines
