Color coated steel plate, the full name is color coated steel plate, which is called color coated steel plate for short.
It is a kind of steel plate with organic coating, with a thickness of about 50 ~ 100mm. It is composed of filler in the middle and color steel plates on both sides.
It is widely used in construction, home appliances, transportation and other industries.
For the construction industry, it is mainly used for the roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport, warehouse and refrigeration.
(1). Light weight: 10-14kg / m2, equivalent to 1 / 30 of brick wall.
(2). Thermal insulation: thermal conductivity of core material: λ<= 0.041w/mk。
(3). High strength: it can be used as ceiling enclosure plate to bear load, bending and compression; General houses do not use beams and columns.
(4). Bright color: no surface decoration is required, and the preservation period of the anti-corrosion coating of color galvanized steel plate is 10-15 years.
(5). Flexible and fast installation: all dry construction is not affected by environmental seasons, and the construction period can be shortened by more than 40%.
(6). Environmental protection: color steel materials can be recycled to truly achieve green and pollution-free.
(7). Energy saving: high efficiency energy-saving wall is adopted, with good thermal insulation, heat insulation and sound insulation effects, which can reach the energy-saving standard of 50%.
The polyurethane foam color steel sandwich panel is made of flame retardant rigid polyurethane foam as core material and color coated steel sheet as the surface color steel plate.
It is used in industrial buildings, warehouses, sports venues, residential buildings, villas, movable board rooms, combined cold storage and other buildings,
but the disadvantage is that it is carried out under the condition of high temperature and strong alkali, which requires high equipment and large initial investment. Industrialization is more difficult.
The advantages of this color steel plate are low price, water resistance and no deformation.
Most of the movable rooms at the construction site are built of polystyrene sandwich panels, which are widely used, but the polystyrene foam sandwich panels are not fireproof, and the thermal insulation effect is very poor.
Phenolic foam color steel sandwich panels are made of colored steel sheets and phenolic foam as core material.
Phenolic foam is brittle, brittle and corrosive. The residual acid in the foam has corrosion effect on metal materials.
The rock wool color steel sandwich board has good fire resistance, but the rock wool color steel plate is not waterproof, which produces toxic substances in case of fire and causes great pollution.
Paper honeycomb sandwich board can recycle waste. It is a replacement product of polystyrene board, polyurethane, rock wool and other materials.
It is widely used in clean engineering fields such as electronics, hospital operating room and laboratory, but its waterproof effect is poor and the price is expensive.
It is made of aluminum honeycomb core plate, which is compounded with special high-strength glue and color steel plate, supported by special aluminum alloy keel and heated, pressurized and solidified.
It has the advantages of light weight and good flatness. It is a green environmental protection building material, but the cost is the highest.
Color coated steel plate is referred to as color coated steel plate for short. This kind of plate has novel surface color, strong adhesion, good corrosion resistance and decoration, and good processing performance.
Therefore, it is widely used in building exterior wall protection board, roof panel, corrugated board, waterproof and anti gas permeability board, corrosion-resistant equipment and components, furniture, automobile shell, water baffle, etc.
Galvanized steel plate is used as the base, and the front and back are coated to ensure its corrosion resistance. The first layer on the front is primer, usually epoxy primer, because it has strong adhesion to metal, and the back is also coated with epoxy resin or acrylic resin;
The second layer (surface layer) used to be alkyd resin, generally polyester coating or acrylic resin coating.
The PVC layer is thermoplastic, and the surface can be hot processed. For example, embossing can enrich the surface texture, and it also has flexibility, which can carry out secondary processing such as bending, and its corrosion resistance is also relatively good.
There are two types of PVC steel plate. One is produced by coating paste PVC, which is called coated PVC steel plate; The other is to stick the formed and printed or embossed PVC film on the steel plate, which is called film coated PVC steel plate.
The heat insulation coated steel plate is made of 15 to 17mm thick polystyrene foam or rigid polyurethane foam on the back of the color coated steel sheet, which is used to improve the performance of the coated steel plate, and is mainly used in special areas requiring heat insulation and sound insulation.
Taking advantage of the good aging resistance of fluoroplastics and acrylic resin, the durability and corrosion resistance of color coated steel plate can be improved by using high durability coated steel plate on the surface coating of steel plate.
