彩钢板的发展趋势与存在的具体问题

天物彩板专注彩板行业17年_由于钢材价格每天都有浮动,详细价格表请拨打网站上方电话咨询

发展趋势:
1、 通过使用高质量的基板,对基板的表面、形状和尺寸精度的要求越来越高。室外使用,如小型锌花扁热浸镀锌钢卷和无锌扁热浸镀锌钢卷及时释放出现的锌合金热浸镀锌钢卷,室内使用为电镀锌钢卷、冷轧箔和铝卷。

2、 改进预处理工艺和预处理液。主要工艺设备少,成本低。预处理液的稳定性、耐腐蚀性和环保性能不断提高。
3、 关注新涂料的开发,改进普通聚酯、聚偏氟乙烯(PVDF)和塑性溶胶,获得超强的颜色再现性,抗紫外线和二氧化硫,提高耐腐蚀性;开发抗污染和吸收功能性涂料,
4、 是的,这个单元比较完整。例如,使用了新的焊接机、新的辊涂机、完善的固化炉和先进的自动化仪器。
5、 由于冷冲压成本低于热冲压,并且具有外形美观、立体效果好、强度高等特点,冷冲压生产技术已成为一种发展趋势。
6、 注重产品的多样化、功能化、高品质,如深冲彩涂板、“柚皮”彩涂板、防静电彩涂板、防污染彩涂板、高吸热彩涂板等,请稍等。
彩钢板存在的问题:
1、建筑材料热镀锌基材消耗量增加,生产能力大,但无锌热镀锌扁钢卷、锌合金镀层钢卷等优质基材缺乏;
2.国产涂料品种和质量不能完全满足需求。进口涂料的高价降低了竞争力。薄膜色板所需的塑料薄膜仍需进口。它缺乏高端色彩、功能性、高强度和色彩丰富的厚涂层。
3.产品标准化不足,造成资源严重浪费。4万吨/年以下低能发电机组过多,产品质量和环境资源保护存在问题;
4.中国新的彩色涂料单位太多,远远超过市场需求。许多彩色涂料装置开工率低,甚至停产。

Development trend:

1、 Through the use of high-quality substrate, the requirements for the surface, shape and dimensional accuracy of the substrate are higher and higher. Outdoor use, such as small zinc flower flat hot-dip galvanized steel coil and zinc free flat hot-dip galvanized steel coil, timely release the emergence of zinc alloy hot-dip galvanized coil, and indoor use as electro galvanized steel coil, cold-rolled foil and aluminum coil.
2、 It is to improve the pretreatment process and pretreatment liquid. The main process is the small number of equipment and low cost. The stability, corrosion resistance and environmental protection performance of the pretreatment liquid are continuously improved.
3、 Pay attention to the development of new coatings, improve ordinary polyester, polyvinylidene fluoride (PVDF) and plastisol, obtain super color reproducibility, resist ultraviolet and sulfur dioxide, and improve corrosion resistance; Develop anti pollution and absorption functional coatings,
4、 Yes, the unit is more complete. For example, new welding machines, new roller coating machines, perfect curing furnaces and advanced automation instruments are used.
5、 Because the cost of cold stamping is lower than that of hot stamping, and has the characteristics of beautiful appearance, good three-dimensional effect and high strength, cold stamping production technology has become a development trend.
6、 Pay attention to the diversification, functionalization and high quality of products, such as deep drawing color coating board, "grapefruit skin" color coating board, antistatic color coating board, anti pollution color coating board, high heat absorption color coating board, etc. Please wait a moment.
Problems of color steel plate:
1. Although the consumption of hot-dip galvanized base materials for building materials has increased and the production capacity is large, there is a lack of excellent base materials such as zinc free hot-dip galvanized flat steel coil and zinc alloy coated steel coil;
2. The variety and quality of domestic coatings can not fully meet the demand. The high price of imported coatings reduces competitiveness. The plastic film required for the film color plate still needs to be imported. It lacks high-end color, functionality, high strength and rich color of thick coating.
3. Insufficient product standardization leads to serious waste of resources. There are too many low energy generating units with a capacity of less than 40000 t / A, and there are problems in product quality and environmental resources protection;
4. There are too many new color coating units in China, which far exceeds the market demand. Many color coating units have low operating rate and even stop production.
