楼梯之家讯：portant; word-wrap: break-word !important;">常用不锈钢表面处理技术有以下几种处理方法：portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">①portant; word-wrap: break-word !important;">表面本色白化处理；portant; word-wrap: break-word !important;">②portant; word-wrap: break-word !important;">表面镜面光亮处理；portant; word-wrap: break-word !important;">③portant; word-wrap: break-word !important;">表面着色处理。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">1.3.1portant; word-wrap: break-word !important;">表面本色白化处理：不锈钢在加工过程中，经过卷板、扎边、焊接或者经过人工表面火烤加温处理，产生黑色氧化皮。这种坚硬的灰黑色氧化皮主要是portant; word-wrap: break-word !important;">NiCr2O4portant; word-wrap: break-word !important;">和portant; word-wrap: break-word !important;">NiFportant; word-wrap: break-word !important;">二种portant; word-wrap: break-word !important;">EO4portant; word-wrap: break-word !important;">成分，以前一般采用氢氟酸和硝酸进行强腐蚀方法去除。但这种方法成本大，污染环境，对人体有害，腐蚀性较大，逐渐被淘汰。目前对氧化皮处理方法主要有二种：
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑴portant; word-wrap: break-word !important;"> 喷砂（丸）法：主要是采用喷微玻璃珠的方法，除去表面的黑色氧化皮。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑵portant; word-wrap: break-word !important;"> 化学法：使用一种无污染的酸洗钝化膏和常温无毒害的带有无机添加剂的清洗液进行浸洗。从而达到不锈钢本色的白化处理目的。处理好后基本上看上去是一无光的色泽。这种方法对大型、复杂产品较适用。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">1.3.2portant; word-wrap: break-word !important;">不锈钢表面镜面光亮处理方法：根据不锈钢产品的复杂程度和用户要求情况不同可分别采用机械抛光、化学抛光、电化学抛光等方法来达到镜面光泽。这三种方法优缺点如下：
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">1.3.3portant; word-wrap: break-word !important;">表面着色处理：不锈钢着色不仅赋予不锈钢制品各种颜色，增加产品的花色品种，而且提高产品耐磨性和耐腐蚀性。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">不锈钢着色方法有如下几种：
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑴portant; word-wrap: break-word !important;">化学氧化着色法；
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑵portant; word-wrap: break-word !important;">电化学氧化着色法；
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑶portant; word-wrap: break-word !important;">离子沉积氧化物着色法；
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑷portant; word-wrap: break-word !important;">高温氧化着色法；
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑸portant; word-wrap: break-word !important;">气相裂解着色法。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">各种方法简单概况如下：
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑴portant; word-wrap: break-word !important;">化学氧化着色法：就是在特定溶液中，通过化学氧化形成膜的颜色，有重铬酸盐法、混合钠盐法、硫化法、酸性氧化法和碱性氧化法。一般portant; word-wrap: break-word !important;">“portant; word-wrap: break-word !important;">茵科法portant; word-wrap: break-word !important;">”portant; word-wrap: break-word !important;">（portant; word-wrap: break-word !important;">INCOportant; word-wrap: break-word !important;">）使用较多，不过要想保证一批产品色泽一致的话，必须用参比电极来控制。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑵portant; word-wrap: break-word !important;">电化学着色法：是在特定溶液中，通过电化学氧化形成膜的颜色。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑶portant; word-wrap: break-word !important;"> 离子沉积氧化物着色法化学法：就是将不锈钢工件放在真空镀膜机中进行真空蒸发镀。例如：镀钛金的手表壳、手表带，一般是金黄色。这种方法适用于大批量产品加工。因为投资大，成本高，小批量产品不合算。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑷portant; word-wrap: break-word !important;">高温氧化着色法：是在特定的熔盐中，浸入工件保持在一定的工艺参数，使工件形成一定厚度氧化膜，而呈现出各种不同色泽。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">⑸portant; word-wrap: break-word !important;"> 气相裂解着色法：较为复杂，在工业中应用较少。
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">1.3 portant; word-wrap: break-word !important;">处理方法选用
portant; word-wrap: break-word !important;">portant; word-wrap: break-word !important;">不锈钢表面处理选用哪种方法，要根据产品结构、材质、及对表面不同要求，选用合适的方法进行处理。
