彩钢板特点
重量轻:10-14千克/平方米,相当于砖墙的1/30。
隔热保泪:芯材导热系数:入<=0.023-0.041w/mk.
强度高:可作天花围护结构板材承重,抗弯抗压:一般房犀不用梁柱,
色泽鲜艳:无需表面装饰,彩色镀锌钢板防腐层保持期在10-25年。
安装灵活快捷:施丁周期可缩短40%以上。
氧指数:(OI)32.0(国家消防产品质检站)。
发展历程
上个世纪80年代末我国才陆续建设彩钢板机组,这些机组多建在钢铁厂及合资企业,彩钢板工艺设备基本从国外引
进。到2000年国产彩钢板达到173万吨,出现了产能过剩。国有特大钢铁企业的机组产能、装备水平较高,都相继
建成了采用国外技术、年生产能力12万~17万吨的彩钢板机组。
许多民营企业投资的彩钢板生产大多采用国产设备,产能较小,但上马快,投资低,产品主要面向建材,装
饰行业。外资、台资也纷纷登陆兴建彩涂机组,但大部分集中在沿海地区。1999年以来,随着彩涂板市场兴
旰,彩涂板的生产及消费进入了快速增长期。
Features of color steel plate
Light weight: 10-14 kg/m2, equivalent to 1/30 of brick wall.
Thermal insulation: thermal conductivity of corematerial:<=0.023-0.041w/mk
High strength: it can be used as ceiling enclosure structural plateto bear the load, bending and compression resistance: generally,beams and columns are not used in the room,
Bright color: no surface decoration is required, and the retentionperiod of the color galvanized steel anti-corrosion coating is10-25 years.
Flexible and fast installation: the construction period can beshortened by more than 40%.
Oxygen index: (OI) 32.0 (National Fire Products Quality InspectionStation).
development history
At the end of the 1980s, China began to build color steel plateunits. These units were mostly built in steel plants and jointventures. Color steel plate process equipment was basicallyimported from abroad
Enter. By 2000, domestic color steel plates had reached 1.73million tons, resulting in overcapacity. Large state-owned iron andsteel enterprises have high unit capacity and equipment level
A color steel plate unit with foreign technology and an annualproduction capacity of 120000-170000 tons has been built.
At the same time, the production of color steel plates invested bymany private enterprises mostly adopts domestic equipment withsmall production capacity, but it is fast to start and lowinvestment. The products are mainly for building materials andpackaging
Decoration industry. In addition, foreign investment and Taiwaninvestment have also landed to build color coating units, but mostof them are concentrated in coastal areas. Since 1999, with thedevelopment of the color coated board market
Finally, the production and consumption of color coated panelsentered a period of rapid growth.
