Description

Color coated coil is based on hot galvanized plate, hot aluminum plated zinc plate, electrogalvanized plate, etc., after surface pretreatment (chemical degreasing and chemical conversion treatment), coated with one or several layers of organic coating on the surface, and then baked and cured products. Also because coated with a variety of different colors of organic paint color steel coil thus named, referred to as color coated coil. In addition to the zinc layer protection, the organic coating on the zinc layer covers and protects the steel strip to prevent rust, and the service life is about 1.5 times longer than that of the galvanized strip.

Color coated roll has light weight, beautiful appearance and good corrosion resistance, and can be directly processed, the color is generally divided into gray, blue, brick red, mainly used in advertising, construction, home appliance industry, electrical appliance industry, furniture industry and transportation industry. The paint used in the color coating volume is selected according to the different use environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on.

Users can choose according to the use. Coating structure v Coating structure type 2/1: the upper surface is coated twice, the lower surface is coated once, and the baking is twice. 2/1M: Paint the upper and lower surfaces twice and bake once. 2/2: Paint the upper and lower surfaces twice, bake twice. v Uses of different coating structures: 2/1: single-layer back paint corrosion resistance, scratch resistance is poor, but has good adhesion, mainly used in sandwich board; 2/1M: The back paint has good corrosion resistance, scratch resistance and processing formability, and has good adhesion, suitable for single-layer molded plate and sandwich plate. 2/2: The double-layer back paint has good corrosion resistance, scratch resistance and processing formability, most of which are used for single-layer pressed plate, but its adhesion is poor, and it is not suitable for the sandwich plate color coated roll substrate classification hot galvanized substrate The organic coating on the hot galvanized steel sheet to obtain the product is hot galvanized color coated plate. In addition to the protective effect of zinc, the organic coating on the surface also plays a role in isolating protection and preventing rust, and the service life is longer than that of the hot galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the zinc content of the hot-dip galvanized substrate for external construction is 275g/m2.

Hot-plated aluminum zinc substrate using hot-plated aluminum zinc steel plate (55%Al-Zn) as the new coating substrate, usually containing aluminum zinc content of 150g/㎡ (double-sided). The corrosion resistance of hot plated aluminum zinc plate is 2-5 times that of hot galvanized plate. Continuous or intermittent use at temperatures up to 490 ° C will not result in severe oxidation or oxide skin. The ability to reflect heat and light is 2 times that of hot galvanized steel, and the reflectivity is greater than 0.75, which is an ideal building material to save energy. Electroplated zinc substrate electroplated zinc plate for the substrate, coated with organic paint baking products for electrogalvanized color coated plate, because the zinc layer of electroplated zinc plate is thin, usually zinc content is 20/20g/m2, so the product is not suitable for use in outdoor production of walls, roofs, etc. However, because of its beautiful appearance and excellent processing properties, it can be mainly used for household appliances, audio, steel furniture, interior decoration and so on. Electroplated zinc substrate: the coating is thinner, and the corrosion resistance is not as good as that of hot-dip galvanized substrate; Hot-dip galvanized substrate: the thin steel plate is immersed in the melted zinc tank, so that the surface adhesion of a layer of zinc, this galvanized plate has good coating tightness and weldability. Hot aluminized zinc substrate: The product is plated with 55% Al-Zn, which has anti-corrosion properties, and its service life is more than four times that of ordinary galvanized steel. It is the replacement of galvanized sheet.

Product features:

(1) Has good durability, corrosion resistance and galvanized steel plate compared with longer life;

(2) has good heat resistance, compared with galvanized steel plate at high temperature is not easy to discolor;

(3) Good thermal reflectivity;

(4) It has similar processing properties and spraying properties to galvanized steel plate;

(5) Good welding performance.

(6) With good performance-price ratio, durable performance and competitive prices.

Therefore, whether it is architectural designers, engineers or manufacturers have been widely used in industrial buildings, steel structures and civil facilities, such as: garage doors, gutters and roofs. Polyester (PE) has good adhesion, rich color, wide range in terms of formability and outdoor durability, medium chemical resistance and low cost. Silicon modified polyester (SMP), the film hardness, wear resistance and heat resistance is good, as well as good external durability and powder resistance, gloss retention, flexibility is general, medium cost. High durability polyester (HDP), excellent color retention and UV resistance, excellent outdoor durability and powder resistance, good film adhesion, rich color, excellent cost performance. Polyvinylidene fluoride (PVDF), excellent color retention and UV resistance, excellent outdoor durability and powder resistance, excellent solvent resistance, good formability, dirt resistance, limited color, high cost
