我车间镀锌用氢氧化钠(NaOH),氰化镀锌或无氰镀锌,历来用化学纯(瓶装)氢氧化钠。在提高质量,降低成本,为四化多作贡献精神鼓舞下,试用工业纯氢氧化钠代替化学纯氢氧化钠,通过两个多月试验,对镀锌产品质量进行分析、鉴定,认为工业纯氢氧化钠可以代替化学纯氢氧化钠,对电镀溶液和产品质量无影响,已投入生产一年多,能满足工艺和质量的要求。工业纯氢氧化钠,每公斤0.90元,而化学纯每公斤19.00元,相差20.5倍。我厂镀锌
My shop galvanized with sodium hydroxide (NaOH), cyanide zinc plating or non-cyanide zinc, has always been chemically pure (bottled) sodium hydroxide. Inspired by our contribution to improving quality, reducing costs and making more contributions to the four modernizations, we tried industrial pure sodium hydroxide instead of chemically pure sodium hydroxide. After more than two months of testing, the quality of galvanized products was analyzed and identified. The industrial pure Sodium hydroxide can replace chemical pure sodium hydroxide, the quality of the plating solution and product has no effect, has been put into production for more than a year to meet the process and quality requirements. Industrial pure sodium hydroxide, 0.90 yuan per kilogram, and chemically pure 19.00 yuan per kilogram, a difference of 20.5 times. I plant galvanized
