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,
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.
