Shandong color steel coil manufacturers: what is color steel coil?

Shandong color steel coil manufacturers introduce, color steel coil is a kind of composite material, also called color coated steel plate. It is made of strip steel, in the production line after the surface degreasing, phosphatization and other continuous chemical transfer treatment, and then coated with organic paint, baking products.

Shandong color steel coil manufacturers said, color steel coil coating can be divided into: polyester (PE), silicon modified polyester (SMP), polyvinylidene fluoride (PVDF), high weathering polyester (HDP) and clinker sol.

Color steel materials are divided into five categories: packaging, home appliances, building materials, optical materials, and decorative materials. Among them, color steel materials for home appliances have better and finer technology and high production requirements.

Related issues:

1. Although the production capacity of hot-dip galvanized substrate for building materials with large dosage is large, there is a lack of good substrates such as flat hot-dip galvanized steel coil without zinc flower and zinc alloy coated steel coil;.

2. Domestic coating varieties and quality can not fully meet the demand, the high price of imported coatings reduces the competitiveness of the plastic film required to paste the color plate still need to be imported, the lack of thick coatings, functional, high strength, colorful color-coated sheet;

3. the product is not standardized enough, resulting in a serious waste of resources. 40,000 tons/year below the low-capacity unit is too much, product quality and environmental resource protection problems;

4. the new color coated unit in the country is too much, far more than the market demand, resulting in a lot of color coated unit start rate is low, or even stop production.

The development trend of color steel coil.

1. Shandong color steel coil manufacturers said, use high quality base material, the surface of the base material, shape, dimensional accuracy requirements are increasingly high, such as outdoor small galvanized flower hot-dip galvanized steel coil, no zinc flower zinc alloy hot-dip galvanized steel coil. Indoor use such as galvanized steel coil, cold rolled sheet with film and aluminum coil.

2 should improve the pretreatment process and pretreatment fluid, less equipment, low cost to become the mainstream process, and constantly improve the stability of the pretreatment fluid, corrosion resistance and environmental performance.

3. Attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plasticizing sol, in order to obtain a strong color reproduction, ultraviolet, sulfur dioxide and corrosion resistance; the development of pollution-resistant, heat-absorbent and other functional coatings.

4. Unit equipment is more complete. Such as the use of new welding machines, new roller coating machine, improve the curing oven, configuration of advanced automation instruments.

5. Due to the cold press has a lower cost than the hot press, beautiful appearance, three-dimensional sense of strong, high strength and other characteristics of the cold press production technology has become a development trend.
