什么是彩钢板

彩钢板有很多品牌,有不同的优缺点。
工程上常用的复合板分为单板和复合板,复合板也分为岩棉复合板和聚苯复合板。单板通常用于车间或棚屋,有些单板将安装额外的岩棉,这被称为“现场复合材料”。复合板墙板多为950型、970型或960型。单板常见于760、820、840、900、127或960,其中760和820用支架固定,其他类型用自攻钉固定。屋顶使用760、820、840多块,墙板使用900多块,屋顶装饰墙板或防悬板使用127或960多块。
彩钢配件在工程中也是必不可少的。屋脊砖、银角、阳角、门窗、小沟道、伸缩缝等,大多用铆钉固定,并用胶密封。
存在的问题
1。尽管建筑材料的热镀锌基板容量很大,但缺乏良好的基板,如无锌火花的平板镀锌钢卷和镀锌合金涂层钢卷。
2。国内涂料的品种和质量不能完全满足需求。进口涂料的高价格降低了竞争力。粘贴色板所需的塑料薄膜仍然需要依靠进口。缺少高档彩涂板,具有厚实、功能性强、强度高、色彩丰富等特点。
三。产品标准化不够,造成资源严重浪费。产能不足4万吨/年的低产能机组太多了。产品质量和环境资源保护方面存在问题。
4。我国新彩绘单位太多,远远超过市场需求。因此,许多彩绘单元启动率低,甚至停产。
发展趋势
首先,随着高质量基板的出现,对基板表面、形状和尺寸精度的要求越来越高。适用于室外使用,如小镀锌扁钢热镀锌卷、无镀锌扁钢的扁钢热镀锌卷、镀锌合金热镀锌卷等;室内使用,如镀锌钢卷、镀膜冷轧板、铝卷等。
其次,为了改进预处理工艺和预处理液,设备数量少,成本低已成为主流工艺,并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,提高通用聚酯、聚偏氟乙烯(PVDF)和塑料溶胶的性能,获得超彩色可重复性、抗紫外线、抗二氧化硫,提高耐腐蚀性;开发抗污染、吸热等功能。铝涂层。
第四,机组设备比较完善。例如,新的焊接机、新的辊涂机、改进的固化炉、先进的自动化仪器等。
第五,冷压纹技术以其成本低、外观美观、立体感强、强度高等特点,已成为发展的趋势。
六是注重产品多样化、功能化、高档化,如深冲彩涂板、“葡萄柚皮”彩涂板、防静电彩涂板、耐污染彩涂板、高吸热彩涂板等。

Colored steel plate has many brands with different advantages and disadvantages.


Generally used in engineering can be divided into veneer and composite board, composite board is also divided into rock wool composite board and polyphenyl composite board. The veneer is usually used in workshop or shed, and some veneers will be installed with additional rock wool, which is called "on-site composite". Composite plate wallboard is mostly 950 type, roof 970 type or 960 type. The veneer is common in 760, 820, 840, 900, 127 or 960, of which 760 and 820 are fixed by brackets and other types are fixed by tapping nails. More than 760, 820 and 840 are used as roofs, more than 900 are used for wallboards, and 127 or 960 are used for decoration of wallboards or anti-suspension boards in roofs.

Color steel accessories are also indispensable in engineering. Ridge tiles, Yinjiao, Yang Jiao, doors and windows, small trenches, expansion joints, etc., are mostly fixed by rivets and sealed by glue.

Existing problems

1. Despite the large capacity of hot-dip galvanized substrates for building materials, there is a lack of good substrates such as flat galvanized steel coils without zinc sparkle and galvanized alloy coated steel coils.

2. The variety and quality of domestic coatings can not fully meet the demand. The high price of imported coatings reduces the competitiveness. The plastic film needed for pasting color boards still needs to rely on imports. There is a lack of high-grade color coated boards with thick, functional, high strength and rich colors.

3. The product is not standardized enough, resulting in serious waste of resources. There are too many low-capacity units with capacity of less than 40,000 tons per year. There are problems in product quality and environmental resources protection.

4. There are too many new color painting units in China, which far exceed the market demand. As a result, many color painting units have a low start-up rate and even stop production.

Trend of development

Firstly, with high quality substrates, the requirements for surface, shape and dimension accuracy of substrates are becoming higher and higher. For outdoor use, such as small galvanized flat hot galvanized coil, flat galvanized coil without galvanized flat and galvanized alloy hot galvanized coil, and for indoor use, such as galvanized steel coil, coated cold rolled sheet and aluminium coil.

Secondly, to improve the pretreatment process and pretreatment fluid, the number of equipment is small, low cost has become the mainstream process, and constantly improve the stability, corrosion resistance, environmental protection performance of the pretreatment fluid.

Thirdly, pay attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastic sol, obtain super color repeatability, anti-ultraviolet, anti-sulfur dioxide, improve corrosion resistance; develop anti-pollution, heat absorption and other functional coatings.

Fourth, the unit equipment is more perfect. For example, new welding machines, new roll coating machines, improved curing furnace, advanced automation instruments and so on.

Fifth, cold embossing technology has become the trend of development because of its low cost, beautiful appearance, three-dimensional sense and high strength.

Sixth, pay attention to product diversification, functionalization, high-grade, such as deep-drawing color coating plate, "grapefruit peel" color coating plate, anti-static color coating plate, pollution-resistant color coating plate, high heat absorption color coating plate, etc.
