Where is the main application of color coated plate in China

Features of pre-painted sheets:

Color-coated steel plate is a composite material, that is, a composite of steel materials and organic materials, so it has the advantages of both: the existing steel plate has high mechanical strength and good easy formability. It also has good decoration and corrosion resistance of the coating material.

Application of pre-painted sheets:

1. Construction industry: Color-coated panels are usually processed into corrugated panels or sandwich panels for construction.

2. In addition, doors and windows, roller shutter doors, and decorative ceilings in the house are used.

3. Household appliance industry: mainly use color-coated plate to make shells. Such as refrigerator door shell, refrigerator side panel, freezer door body, washing machine shell, microwave oven shell, air conditioner side panel, water heater shell, etc.

The physical properties of the surface of the pre-coated sheet coating include:

The thickness of the coating film, the integrity of the coating film, the hardness, gloss and color of the coating film.

There are two main uses of color-coated sheets: for home appliances and building materials.

Building materials are mainly used in China to make sandwich panels, the color is mostly blue, now many factory buildings, temporary sheds at construction sites, is made of steel structures and sandwich panels, the construction speed is fast, the materials are provincial, but also strong, the ability to resist earthquakes is also strong, and the temporary shed can be reused after dismantling. A little lesser, it is directly made into a corrugated type, and there are many around the construction site that are surrounded by color-coated boards. Foreign countries are mainly used as sandwich panels and roof tiles, and the performance requirements are much higher than those in China.

The range of household appliances is too wide: refrigerators, freezers, air conditioners, washing machine panels, side panels, TV back panels, solar water heaters, hot water cylinder panels, etc.

The main uses of color-coated sheets:

Construction industry Roofs, roof components, balcony panels, window sills, newsstands, warehouses, roller shutters, heaters, storm sewers, etc.

Household appliances refrigerators, washing machines, switch cabinets, air conditioners, microwave ovens, bread makers, photocopiers, vending machines, electric fans, vacuum cleaners, etc.

Furniture industry lampshades, wardrobes, tables, bookshelves, counters, signboards, medical equipment, etc.

Transportation industry Automobile ceilings, car shells, compartment panels, tractors, trams, containers, highway fences, ship bulkheads, etc.

Miscellaneous Musical instrument housings, bins, billboards, clocks, photographic equipment, measuring instruments, etc.

The largest amount is used in car bodies.

<> "The difference between color-coated sheet and laminated sheet.

1. The substrate is different.

The substrate used in these two types of plates is different, for the color-coated plate, it mainly uses cold-rolled steel plate as the base material, and then the surface is processed to make a finished product. Instead, galvanized steel sheet is used as the base material and molded using baking technology.

2. Different characteristics.

For color-coated sheets, not only does it have good colorability, but it is also easy to mold. At the same time, it also has the characteristics of corrosion resistance, high strength and easy delivery. The laminated board has a certain thickness, which can play a role in anti-fume, anti-wear and moisture-proof, and also has a variety of colors, and has a wide range of selectivity.

3. The advantages are different.

In the production and manufacturing process of the laminated board, the scratches on the raw materials can be removed, and the decorative effect is very good. The appearance of the color-coated plate is beautiful and bright, and the strength is very high.

Precautions for the purchase of color-coated plates.

1. Appropriate material selection.

When you buy a color-coated board, the first thing to pay attention to is that the choice must be appropriate, and you must determine the purpose or conditions of purchase in advance, and then choose according to this. Only in this way can we select the plate that can meet the requirements of use, and also avoid the phenomenon of spending more money, which is the so-called reasonable material selection.

For example, for projects with high requirements in the town, it is necessary to ensure that the color-coated board can meet the requirements of use in the purchase process to avoid the phenomenon of unusability and failure to meet the requirements.

2. Determine the direction of selection.

For color-coated plates, we need to determine the direction of rotation, such as the mechanical properties of the plate, the type of substrate, the front and back coatings, etc., which are all places that need to be paid attention to when purchasing.

The main production processes of the common two-coating and two-drying continuous color coating unit are: uncoiler--- sewing machine--- pressure roller--- tensioning machine--- uncoiling looper--- alkali elution degreasing --- cleaning--- drying--- passivation--- drying --- initial coating--- initial coating drying--- topcoat fine coating --- topcoat drying --- air-cooled cooling ---winding looper---winder ---unroll packaging and warehousing).

In the construction of buildings or large-scale decoration, color-coated boards may be used, so what is color-coated boards? The main reason why color-coated plates are widely used in our lives is that color-coated plates have good anti-corrosion properties, and are easy to process and transform, and are lighter than plates of other materials, so color-coated plates will receive great attention in the construction market. So, what is a pre-painted sheet and what is the market use of a pre-painted sheet?

Color-coated sheet is a new type of composite material, which has two types: PCM and VCM. What are composites? Presumably, many people have doubts, composite materials are composed of organic polymers, inorganic non-metals or metals and other different materials through the combination of several different materials through the composite process of a new type of materials.

Color-coated sheets are used in a wide range of fields, including construction, home appliances and transportation. In the field of construction, because the color-coated steel plate has lightweight, beautiful and anti-corrosion properties, it is widely used in the construction of roofs and walls of industrial and commercial buildings such as steel structure workshops, warehouses, freezers, etc.

In the field of home appliances, color-coated sheets are used to produce the surfaces of household appliances such as refrigerators and microwave ovens. In transportation, color-coated sheets are used in the production and processing of oil pans, automotive interior parts, etc. The market use of color-coated plate is mainly divided into three parts: construction, home appliances and transportation, of which the construction field accounts for the largest proportion, followed by the home appliance industry, and the transportation industry only accounts for a small part.

Color-coated plate for construction is generally based on hot-dip galvanized steel sheet and hot-dip aluminum-galvanized steel sheet, which is mainly processed into corrugated board or sandwich panel in line with polyurethane, and is used for the roof, wall and door of industrial and commercial buildings such as steel structure workshops, airports, warehouses, freezers, etc. Home The electrocolor board is generally based on electro-galvanized and cold plates, which are used in the production of refrigerators and large air conditioning systems, freezers, bread machines, furniture, etc. In the transportation industry, electro-galvanized and cold plates are generally used as substrates, mainly used for oil pans, automotive interior parts, etc.

Color coated plate color coated coil uses galvanized steel plate as the substrate of color coated steel plate, in addition to zinc protection, the organic coating on the zinc layer plays a role in covering isolation, can prevent steel rust, the service life is longer than galvanized steel plate, according to the introduction, the service life of coated steel plate is 50 longer than galvanized steel plate.

However, in different regions and different parts of use, the color coated plate with the same amount of galvanization, the same kind of coating, and the same coating thickness will be very different in its service life. For example, in industrial areas or coastal areas, due to the action of sulfur dioxide gas or salts in the air, the rate of corrosion is accelerated and the service life is affected. Most of the color-coated plates on the market are used in the construction industry, and a very small part will be used in other industries, such as aviation, transportation, etc., which means that the importance of color-coated plates for the construction industry can also be said to be irreplaceable.

However, as ordinary people, we don't need to know too much about the knowledge of the color-coated plate, we only need to know what the color-coated plate is and what are the important uses in the color-coated plate market.

Introduction: Color-coated board, I believe that everyone often sees this material in life. For example, many shed-style houses, most of them can be seen on the top of the house coated plate, color coated board in the industry can also be called color steel plate or color plate.

The word "color" contained in the name also reflects the aesthetic characteristics of this material. So, what are the types of common color-coated sheets in life and what is their price.

(1) Classification of color-coated plates

Cold-rolled base color-coated plate is generally used in an environment where the requirements for whether the color-coated plate is easy to rust are not high. In general, it is more suitable for interior decoration or temporary isolation baffle use.

Hot-dip galvanized color coated sheet, which is a layer of coating mainly containing zinc on the surface of the color plate. This type of pre-painted sheet has better corrosion resistance. The material inside the layer of zinc color coated plate on its surface has a good protective effect.

Hot-dip aluminum-zinc color-coated sheet, this type of corrosion resistance is much better than the former. Because this type of prepainted sheet has an extra element "aluminum" added to the surface of the steel plate than the former. This kind of steel plate is used more outdoors and can have good corrosion resistance.

Electro-galvanized color-coated sheet, this color-coated sheet has less zinc content and is not suitable for outdoor use, that is, the corrosion resistance is not particularly strong. However, this electroplated zinc color coated sheet has a good appearance and is mostly used in interior decoration. This material is used in the production of furniture and sound.

This is probably the kind of color-coated board that is closest to our lives.

b) Color-coated plates.

The minimum of hot-dip aluminum-zinc color-coated plate is about four thousand, and such a mountain is slightly more expensive in the same category. The highest can reach 7,000 to 8,000 yuan. Most of the prices are between $4,000 and $5,000.

In terms of buying lines, the purchase rate of consumers is still more.

The ** of cold-rolled base color-coated plate is generally distributed in the range of 3,000 yuan to 6,000 yuan. **The specific situation is still related to its material and quality. This kind of color-coated plate is generally a relatively common type on the market, and you may be able to see it when you look up inadvertently.

The ** of electro-galvanized color-coated sheet is more civilian. Its highest is between four thousand and five thousand yuan, and the lowest is one thousand yuan. Therefore, most of the electro-galvanized color-coated plates are also distributed in 2,000 to 3,000 yuan.

Conclusion: When buying color-coated plates in the market, we should pay attention to his specific types and applicable occasions. Of course, it should not be forgotten that the quality of the goods is the first condition that needs to be paid attention to.

Otherwise, if you buy an unsuitable color-coated board, if the material cannot be used perfectly, it will also bring problems and troubles to the buyer, and finally it will become more than worth the loss.
