聚氨酯薄膜是一种具有高强度、耐磨、弹性好,并且具有微细小孔结构的薄膜。上海光学镜头厂利用PC-1500型微处理机和软件对透镜高速抛光模具的数据进行了计算,改装了机床。采用广州冶炼厂73-9型氧化铈抛光剂进行了大量的工艺试验工作,最后在抛光过程中能采取高压、高速,达到了定时、定光圈。在抛光反光镜色片中,由原来的平均合格率65%提高到77%。平光面的合格率由65%提高到93%。还对其他八种类型的基片进行了工艺试验,平均合格率达到90%,在质量上有明显的提高。每盘抛光时间由8小时减少到3.5小时至4小时。工人看台能力,从该厂的试验记录中可以看到,在抛光
Polyurethane film is a film with high strength, wear resistance, good elasticity, and has a fine pore structure. Shanghai Optical Lens Factory using PC-1500-type microprocessors and software for high-speed lens polishing lens data were calculated and modified machine tools. Guangzhou Smelter 73-9 type cerium oxide polishing agent carried out a large number of process test work, the last in the polishing process can take high-pressure, high speed, to achieve a fixed, fixed aperture. Polished mirror color film, from the original average pass rate of 65% to 77%. Flat surface pass rate increased from 65% to 93%. Also on the other eight types of substrate for the process test, the average pass rate of 90%, a significant increase in quality. Polishing time per plate reduced from 8 hours to 3.5 hours to 4 hours. Worker stands capacity, as can be seen from the plant’s trial records, in polishing
