沈阳镀锌彩钢板应用行业有哪些

镀锌彩钢板主要应用行业:大量镀锌彩钢板应用于汽车制造、冷藏箱、建筑业、通风采暖设施、家具制造等领域。锌不仅对钢铁表面有重要的保护作用,而且对钢铁表面也有重要的保护作用。当镀锌层损坏时,仍能通过阴极保护来防止铁基金属的腐蚀。

近年来,随着镀锌工艺的发展和高性能镀锌光亮剂的应用,镀锌已从单纯的防护目的向防护装饰应用转变。镀锌液有两种:氰化物镀液和无氰镀液。氰化物镀液分为微氰、低氰、中氰、高氰。无氰镀液包括碱性锌酸盐镀液、铵盐镀液、硫酸盐镀液和无氨氯化物镀液。氰化镀锌液具有良好的镀液性能, 镀锌彩钢板镀层光洁,已在生产中长期使用。然而,由于其毒性大、环境污染严重,近年来人们采用了低氰、微氰和无氰镀锌液。
建筑业: 镀锌彩钢板屋面、屋面构件、阳台面板、窗台、报亭、仓库、卷帘门、取暖器、雨水管道等
家用电器:冰箱、洗衣机、开关柜、空调、微波炉、面包机、复印机、自动售货机、电扇、吸尘器等家具行业:灯罩、衣柜、桌子、书架、柜台、招牌、医疗器械等 
交通运输行业:汽车顶棚、车壳、车厢板、拖拉机、电车、集装箱、公路护栏、船舶舱室板等方面的彩涂钢板,如乐器外壳、垃圾箱、广告牌、钟表、摄影器材、计量装置等,是以热镀锌板、热浸铝为基础的镀锌板、镀锌板等,表面预处理后

Main application industries of galvanized sheet: a large number of galvanized sheet are used in automobile manufacturing, refrigerated box, construction industry, ventilation and heating facilities, furniture manufacturing and other fields. Zinc plating has become an important anti-corrosion method for iron and steel, not only because zinc can form a dense protective layer on the steel surface, but also because zinc has cathodic protection effect. When the zinc coating is damaged, it can still prevent the corrosion of iron base metal by cathodic protection.

In recent years, with the development of zinc plating process and the use of high-performance brightener for zinc plating, zinc plating has changed from simple protection purpose to protection decoration application. There are two kinds of zinc plating solution: cyanide plating solution and non cyanide plating solution. Cyanide plating bath is divided into micro cyanide, low cyanide, medium cyanide, and high cyanide. Cyanide free plating solutions include alkaline zincate bath, ammonium salt plating solution, sulfate plating solution and ammonia free chloride plating solution. Cyaniding zinc plating solution has good plating ability and smooth and fine coating, which has been used for a long time in production. However, due to its high toxicity and serious environmental pollution, low cyanide, micro cyanide and non cyanide zinc plating solutions have been adopted in recent years.
Construction industry: roof, roof components, balcony panel, windowsill, kiosk, warehouse, rolling shutter door, heater, rainwater pipeline, etc
Household appliances: refrigerator, washing machine, switch cabinet, air conditioner, microwave oven, bread maker, copier, vending machine, electric fan, vacuum cleaner and other furniture industries: lampshade, wardrobe, table, bookshelf, counter, signboard, medical equipment, etc
Transportation industry: automobile ceiling, car shell, carriage board, tractor, tramcar, container, highway fence, ship compartment board and other aspects of color coated steel plate, such as musical instrument shell, dustbin, billboard, clock, photographic equipment, metering device, etc., is based on hot-dip galvanized sheet, hot-dip aluminum zinc plate, galvanized plate, etc., after surface pretreatment
