这是 一个网站 上面有比较详细的介绍 你可以看看另外还有一些资料,希望对你有帮助:Surface Treatment Code Method and Application Surface ConditionNo.1 This is a product that has undergone annealing and pickling treatment after hot rolling. It is used in cold rolling materials, industrial tanks, and industrial chemical devices. No.2D No. 2D is a non-glossy cold-rolled product that has undergone annealing and pickling treatment after cold rolling. Used in petrochemical plants, automobile parts, building materials, and pipes. No.2B No. 2B is the type that had skin-pass (temper-rolling) performed on No.2D. It has better gloss and surface flatness compared to No.2D. It is the standard surface class with improved mechanical properties. It is applicable for almost all uses. No.3 No. 3 is polished with 100~120 mesh abrasive. It has a variety of uses including building exterior and interior, casings for various kinds of home appliances, and kitchen installations. No.4 No. 4 is polished with 150~180 mesh abrasive. Compared to No.3, this product has a finer abrasion condition. Its surface is an attractive silvery-white and is used for bathtubs, building exterior and interior,and food industry. BA BA is bright and highly reflective surface produced by bright annealing after cold rolling. BA is used in home appliances, small-sized mirrors, kitchenware, building materials and others that require reflective properties. HL HL is a type of surface with continuous striped pattern acquired by polishing the surface with No.4 abrasive. It is widely used for building exterior and interior. HL is also used in sashes and doors. Dull Dull surface is matte finish produced by reducing gloss from No.2B and creating roughness on the surface. It is widely used in building exterior and interior, roofing and elevators that require reduced light reflection. 现在不锈钢的发展,已使不锈钢的耐蚀性、外观、加工性、强度等特性远远超过其它材料,而且,不锈钢的许多表面处理法,可以取得丰富多彩的颜色及形状,这为不锈钢的发展作出很大的贡献。 不锈钢制造过程中的表面处理法以及机械研磨表面处理法表面 特征 制造法概要 用途NO.1 银白色,无光泽 热轧到规定厚度,再经退火和除鳞的一种粗糙、无光表面 不需要有表面光泽的用途NO.2D 银白色 冷轧后进行热处理和酸洗,有时在毛面辊进行最终的一道轻轧的一种无光表面加工 2D产品用于对表面要求不严的用途,一般用材,深冲用材NO.2B 光泽强于NO.2D NO.2D处理后,经过抛光辊进行最终一道轻度冷轧,以取得适当光泽。这是最常用的表面加工,该加工也可作为抛光的第一步。 一般用材BA 光亮如镜 无标准,但通常是光亮退火的表面加工,表面反射性很高。 建筑材料,厨房用具NO.3 粗研磨 将NO.2D和NO.2B材,用100~200#(单位)的砥粒研磨带,进行研磨 建筑材料,厨房用具NO.4 中间研磨 将NO.2D和NO.2B材,用150~180#砥粒研磨带进行研磨而获得的抛光表面,这是通用的,有镜面反射的带有可见‘晶粒’的光亮表面 同上NO.240 细研磨 将NO.2D和NO.2B材,用240#砥粒研磨带进行研削 厨房用具NO.320 极细研磨 将NO.2D和NO.2B材,用320#砥粒研磨带进行研削 同上NO.400 光泽接近于BA 将NO.2B材,用400#抛光轮进行研削 一般用材,建筑用材,厨房用具HL 发纹研磨 适当粒子大小的研磨材料进行发纹研削(150~240#)其砥粒很多 楼房,建筑用材NO.7 接近于镜面研磨 用600#回转抛光轮进行研磨 美术用,装饰用NO.8 镜面研磨 镜子用抛光轮进行磨

大家好,我是专业做皮具五金的,各种五金我都很了解,下面给大家分享下五金知识。因为夏天手心容易出汗,汗水是酸性的,加上真皮本身酸性成份,所以接触起来容易产生化学反应氧化五金,这是正常的现象,干燥和潮湿的环境都会导致五金氧化,比如平常我们戴的耳环,耳针哪里容易发黑,是因为直接性接触人的皮肤,所以容易被氧化,还有就是我们戴的黄金碰到强烈的化学物品,比如水泥,石灰都会导致黄金氧化,教大家的知识都在这里。希望能帮到大家,谢谢!
