Basic knowledge of color steel plate
What call color board: point to besmear on steel plate organic coating, coating can have all sorts of different color, color coating steel plate gets its name from this, abbreviation color board, also call organic coating steel plate. The organic coating of the colored coating board has the function of covering isolation, which can prevent the steel plate from rusting and has a longer service life. The surface state of painted board can be divided into normal coated board, embossed board, printed board, market USES are mainly divided into construction, home appliances and transportation.
1, the origin of steel coil
At present the domestic market steel coil production area variety, domestic production steel coil manufacturers are: baosteel, masteel, shougang, anshan steel, etc. Joint venture steel coil manufacturers: bosge, jiangyin united, changshu ye hui.
2. Specification of steel coil
Color steel plate width from 700mm-1250mm, we often use the width of 1070mm, 1250mm, 1000mm, 1200mm, etc. Thickness can vary from 0.35mm1.2mm. We commonly use thickness of 0.4mm, 0.45mm, 0.53mm, 0.55mm, 0.6mm, etc.
3. Coated steel plate
(1) color steel plate coating
Different coating types can be selected according to the surrounding environment of the building. It is mainly divided into four types: polyester (PE), silicon modified polyester (SMP), high weather resistant polyester (HDP), polyvinylidene fluoride (PVDF).
Polyester: also known as PE (common) coating. Its main features are good adhesion, rich color, wide range of molding and outdoor durability, medium chemical resistance and low cost. (coating life 5-7)
Silicon modified polyester: also called SMP coating, the main characteristics of the coating film is good hardness, wear resistance and heat resistance, as well as good external durability and resistance to pulverization, gloss retention, flexibility - normal, medium cost. (coating life 10-15 years)
High weather resistance polyester: also known as HDP coating, the main characteristics are color retention and uv resistance performance, outdoor durability and excellent powder resistance, paint film adhesion, color rich, excellent cost performance. (coating service life of 15 years)
Polyvinylidene fluoride: also known as PVDF coating, the main feature is the color of the preservation and anti-uv performance excellent, outdoor durability and anti-powder excellent, good molding, anti-expansion, but the color is limited, high cost. (coating service life of 20 years)
(2) self-cleaning products
Selfcleaning color plate is a new type of color coated steel plate for outdoor construction. Its organic coating has not only the high decorative and weather resistance of ordinary color plate, but also the special selfcleaning function. The workshop made of this material does not need manual cleaning and maintenance, but only with the help of the erosion of rain water can maintain the bright color of the roof and wall color board in the industrial and urban areas with poor air quality, and maintain the high decorative color coating. Excellent hydrophilicity can ensure that rain water fully spread on the surface of the coating and have a good scouring effect.
(3) coating structure type
According to the type of coating structure can be divided into two coating one baking, two coating two baking.
Two coating and one baking (2/1) : apply the upper surface of the board twice, apply the lower surface once and bake twice: apply the upper and lower surface of the board twice and bake twice; Second coating and second baking (2/2) : apply and bake the upper and lower surfaces of the board twice;
USES:
2/1: the back is yellow-green. The paint on the back of single layer has poor corrosion resistance and scratch resistance, but it has good adhesion. It is mainly used for lightweight board and polyurethane composite board:
2/1m: the back is white. The paint on the back of the single layer has good corrosion resistance, scratch resistance and processing molding. It has good adhesion.
2/2: the back is white, double-layer back paint corrosion resistance, scratch resistance and processing molding better, more used for single-layer pressure plate, but its bonding is not good, not suitable for light board, polyurethane composite board. Relative to the first two, the price is about 100 yuan /T more expensive.
5, base plate
Engineering, commonly used color steel plate substrate - generally divided into galvanized and aluminum zinc plating two. Before 2010 ordinary galvanized amount - generally refers to 180 g /m2 (double-sided), namely Z180; Aluminum zinc plating is generally 150 g /m2 (double-sided), namely, AZ150; For the best PVDF coating plate, corresponding galvanized, aluminum zinc plating requirements than other coating requirements are higher, baosteel provisions galvanized PVDF color plate substrate galvanized at least 220 g /m2 (double-sided) or 275 g /m2 (double-sided), PVDF color plate substrate aluminum zinc plating must be 150 g /m2 (double-sided).
With the increasingly fierce competition in the market, in order to save costs, at this stage for a general amount of galvanized, aluminum zinc volume requirements have been reduced, the current market on the conventional spot galvanized amount has been reduced to 140 grams /m2, the conventional aluminum zinc has been reduced to 100 grams /m(aluminum zinc plate aluminum zinc AZ150).
6. Identification of intensity
G300 and G550: the standard method of borsig steel coil, G300 refers to yield strength above 300MPA, tensile strength 380-430mpa, G550 refers to yield strength above 550MPA, tensile strength 650-750mpa. But the domestic standard law and bosge are different, generally according to brand to order.
Such as baosteel painted plate number one - general use: TSt01+Z, TDC51D+Z, TS280GD+Z, TS350GD+Z, TS550GD+Z. Substrate plate number one - general use: St01+Z, DC51D+Z, S280GD+Z, S350GD+Z, S550GD+Z. If you have an aluminized zinc plate and you replace the Z with AZ.
