山西岩棉彩钢板的主要机组和结构形式

上世纪80年代末,我国彩钢板生产厂家开始建设彩钢板机组。这些装置大多建在钢铁厂和合资企业中。彩钢板加工设备基本上是从国外进口的。到2000年,国产彩钢板达到173万吨,产能过剩。国有特大型彩钢板生产厂家的生产能力和设备水平较高,先后建成了具有国外技术、年生产能力12万-17万吨的彩钢板厂。


同时,许多彩钢板生产厂家民营企业投资的彩钢板生产大多采用国产设备,生产能力小,但速度快,投资少。产品主要用于建材、装饰等行业。此外,外资和台资也纷纷登陆建设彩涂单位,但大多集中在沿海地区。1999年以来,随着彩涂板市场的繁荣,彩涂板的生产和消费进入了快速增长期。从2000年到2004年,产量平均增长39.0%。到2005年,我国彩涂板生产能力已超过800万吨/年。目前仍有多家彩涂单位在建,总产能超过900万吨/年。
成型前是卷材,成型后有很多型号,常用的有:820、840、900等!其组成结构为:保护膜(现已淘汰)、聚酯漆、镀锌层、钢板(冷轧板和热轧板),背面顺序相同!以上分析并不代表权威!
不同的钢板有不同的优缺点。
彩钢板生产厂家一般工程中可分为单板和复合板,复合板又可分为岩棉复合板和聚苯复合板。有些车间用的是复合材料单板,一般称为“岩棉棚”。950型是常见的复合板墙板类型,970或960型屋面板居多。然而,760、820、840、900、127或960个单板是常用的。760和820用支架固定,其他型号用自攻螺钉固定。760、820、840多用于屋顶,900多用于墙板,127或960用于墙板或天花板反向挂板装饰。
彩钢配件也是项目中不可缺少的。屋脊瓦、阴角、阳角、门窗洞口、小天沟、伸缩缝等用铆钉固定,用胶水密封。


At the end of 1980s, China began to build color steel plate units. Most of these units were built in iron and steel plants and joint ventures. The color steel plate process equipment was basically imported from abroad. By 2000, the domestic color steel plate reached 1.73 million tons, resulting in overcapacity. The production capacity and equipment level of state-owned super large iron and steel enterprises are relatively high, and they have successively built color steel plate mills with foreign technology and annual production capacity of 120000-170000 tons.

At the same time, the production of color steel plate invested by many private enterprises mostly uses domestic equipment, with small production capacity, but it is fast and low investment. The products are mainly for building materials and decoration industries. In addition, foreign capital and Taiwan capital have also landed to build color coating units, but most of them are concentrated in coastal areas. Since 1999, with the prosperity of color coated board market, the production and consumption of color coated plate has entered a period of rapid growth. From 2000 to 2004, the production increased at an average rate of 39.0%. By 2005, the production capacity of color coated sheet in China is more than 8 million tons / year. There are still a number of color coating units under construction, with the total production capacity of more than 9 million tons / year.
Before forming is coil material, after forming there are many models, the most commonly used are: 820, 840, 900 and so on! Its composition structure is: protective film (now obsolete), polyester paint, zinc coating, steel plate (cold-rolled plate and hot-rolled plate), back in the same order! The above analysis does not represent authority!
There are many brands of color steel plate with different advantages and disadvantages.
In general engineering, it can be divided into single board and composite board, and composite board can be divided into rock wool composite board and polyphenylene composite board. Generally, veneers are used in workshops or sheds; some veneers are installed with rock wool, which is called "field composite". Type 950 is the most common type of composite plate wall panel, and 970 or 960 type of roof plate is the majority. However, 760, 820, 840, 900, 127 or 960 veneers were commonly used. 760 and 820 were fixed with brackets, and other models were fixed with self tapping screws. 760, 820, 840 are mostly used as roof, 900 are mostly used for wall panel, 127 or 960 are used for wall panel or ceiling reverse hanging plate decoration.
Color steel accessories are also indispensable in the project. Ridge tiles, internal corners, external corners, door and window openings, small gutters, expansion joints, etc., are fixed with rivets and sealed with glue.
