Product Introduction

Color coated plate, the industry is also called color coated steel plate, color coated steel plate, color plate, color plate, color coated roll. The color plate is cold rolled steel plate, galvanized steel plate, galvanized steel plate as the substrate, through the following processes: 1) surface pretreatment (degreasing, cleaning, chemical conversion); 2) continuous coating with roller coating or Multi-layer liquid coating; 3) Baking; 4) Plate products made by cooling these several process steps. Because the coating can have a variety of colors, it is also called color coated steel. The color coated board is lightweight, beautiful, has good corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, and electrical industry, and it has played a role On behalf of wood, efficient construction, energy conservation, pollution prevention and other good results.

Color coated board classification: According to the substrate type can be divided into: hot-dip galvanized color coated sheet, hot-dip galvanized steel coated sheet, cold-rolled substrate color coated sheet.

In accordance with the use can be divided into: building exterior, building interior use, furniture, home appliances, steel windows, and other uses.

It can be divided according to the type of coating material: polyester, silicone modified polyester, high durability, polyester, polyvinylidene fluoride.

According to the coating surface state can be divided into: coating plate, embossed plate, printing plate. For details, see: Coated coating surface conditions.

Color Coated Plate Process: Common two-coat two-baking type continuous color coating unit process flow The main production process is: uncoiler-stitching machine-pressure roller-intensifier-opening looper-alkali-eluting fat-cleaning-drying – Passivation – Drying – Priming – Priming Drying – Topcoat Finishing – Topcoat Drying – Air Cooling – Rolling Looper – Winder – Down Roll Packed. See details: color coated process flow.

Color plate development trend:

1, the use of higher quality substrates, the substrate surface, shape and dimensional accuracy requirements are increasing.

2, improve the pretreatment process and pretreatment fluid, a small number of equipment, low cost becomes the mainstream process, and continuously improve the stability of pretreatment fluid, corrosion resistance, environmental protection performance.

3. Develop new coatings to improve color reproducibility, UV resistance, and corrosion resistance; develop functional coatings that are resistant to contamination and heat absorption.

4, the unit equipment is more perfect.

5, cold embossing is cheaper than the hot embossing, beautiful appearance, strong three-dimensional sensation, high strength, so cold embossing production technology has become a development trend.

6, pay attention to the diversification of products, functional, high-grade, such as deep-drawing color plate, “pomelo skin” color coated plate, anti-static color coated plate, stain-resistant color coated plate, high heat-absorbing color coated plate .
