彩钢卷成分

彩钢板卷是一种复合材料,又称彩涂钢板。它是在生产线上对带钢表面进行脱脂、磷化等连续化学转移涂层后,涂上有机涂层并烘烤而成的产品。彩钢卷是一种集钢板和有机材料于一体的复合材料。彩钢板卷它不仅具有钢板的机械强度和易成型性能,而且具有良好的装饰性和有机材料的耐腐蚀性。

彩钢板卷的涂层类型可分为:聚酯(PE)、硅改性聚酯(SMP)、聚偏氟乙烯(PVDF)、高耐候聚酯(HDP)、熟料溶胶。
彩钢材料分为五大类:包装、家用电器、建材、光学材料和装饰材料。其中,家电彩钢的工艺是最好、最精的,生产要求也最高。
发展趋势:
一是 彩钢板卷采用优质基材,对基材表面、形状和尺寸精度要求越来越高,室外使用的小镀锌扁钢卷、锌合金热浸镀锌钢卷等及时上升;室内使用如镀锌钢卷、镀膜冷轧板和铝卷等。
二是改进预处理工艺和预处理液,设备少,成本低,成为主流工艺,不断提高预处理液的稳定性、耐腐蚀性、环保性能
三是注重新型涂料的开发,提高普通聚酯、聚偏氟乙烯(PVDF)和塑料溶胶,获得超彩色再现性、抗紫外线、抗二氧化硫,提高耐腐蚀性;开发耐污染、吸热等功能性涂料。
四是单位设备更加完善。如采用新型焊机、新型滚涂机、完善的固化炉、配置先进的自动化仪表等。
第五,冷压花生产技术以其成本低、美观、立体、强度高等特点成为发展趋势。

Color steel materials are divided into five categories: packaging, household appliances, building materials, optical materials and decorative materials. Among them, the technology of home appliance color steel is the best and the most refined, and the production requirements are the highest.

Development trend:
First, the use of high-quality substrate, the substrate surface, shape and dimensional accuracy requirements are increasingly high, outdoor use such as small zinc flat hot-dip galvanized steel coil, zinc alloy hot-dip galvanized steel coil rising in time; indoor use such as galvanized steel coil, coated cold-rolled plate and aluminum coil.
Second, improve the pretreatment process and pretreatment fluid, less equipment, low cost, become the mainstream process, constantly improve the stability, corrosion resistance, environmental performance of the pretreatment fluid
Third, pay attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastic sol to obtain super color reproducibility, UV resistance, sulfur dioxide resistance, and improve corrosion resistance; develop pollution resistance, heat absorption and other functional coatings.
Fourth, the unit equipment is more perfect. Such as the use of new welding machine, new roller coating machine, perfect curing furnace, configuration of advanced automation instruments, etc.
Fifthly, the cold embossing production technology has become the development trend because of its low cost, beautiful, three-dimensional and high strength.
