First, what is color coated aluminum roll?
Color coated aluminum coil is a new type of metal decoration material made of high quality aluminum alloy plate by surface spraying or rolling. Because of its rich color, beautiful appearance, convenient processing and forming, it is widely used in indoor and outdoor architectural decoration projects.
Two, color coated aluminum coil use characteristics:
1. Weather resistance: the coating has good corrosion resistance and UV resistance; It can be used outdoors for more than 15 years without fading.
2. Durability: The service life of the coating can be up to 25 years.
3. Environmental protection performance: The product conforms to the European standard (ROHS directive) and the Chinese national standard GB18583-2001, does not contain formaldehyde, benzene and other harmful substances and harmful gases, no radioactive substance release, is a non-toxic environmental protection products;
4. Decorative effect: rich and varied colors, can be customized according to user requirements of various color patterns; The pattern is clear and smooth and durable without discoloration.
5. Fireproof performance: the coating has self-cleaning function and certain fireproof performance; The fire resistance grade is B1 (refractory), which does not promote combustion and spread in case of fire and can effectively inhibit the toxic gas produced after combustion.
6. Construction convenience: the requirement of environmental temperature is not high during construction, which can be carried out in the range of -10°C~40°C;
7. Economical and practical type: moderate price, cost-effective.
Three, color coated aluminum coil types
Color coated aluminum coil coating is divided into: polyester coated aluminum coil (PE), fluorocarbon coated aluminum coil (PVDF). After baking and coating the surface of the aluminum plate for many times, the polyester coating can form a solid film with strong adhesion and protection decorative properties. Is a kind of anti-UV UV coating, polyester resin is the main chain containing ester bond polymer as a monomer, add alkyd resin, UV absorbent according to gloss and can be divided into matte and highlight series. Can give color aluminum products rich color, but also has good gloss and smoothness, and superior texture and feel, can also increase the sense of layer and three-dimensional. Can protect objects exposed to the atmosphere, ultraviolet radiation, wind, rain, frost and snow attack; The coating provides protection due to temperature differences, freeze-thaw cycles, corrosive gases and microorganisms. Especially suitable for interior decoration and advertising board.
Fluorocarbon Coated Color Coated Aluminum Coil (PVDF)
Fluorocarbon coating is PVDF resin mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride and other small amount of fluorinated vinylmonomer copolymer coating. The chemical structure of the fluoric acid base is bonded by a fluorine/carbonization bond. The stability and firmness of the chemical structure make the physical properties of fluorocarbon coatings different from those of general coatings. In addition to the mechanical properties of wear resistance, impact resistance has excellent performance, especially in the harsh climate and environment shows long-term fading resistance, UV resistance. After high temperature grilling, the molecular structure of the coating is tight and has super weather resistance. Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano fluorocarbon coatings according to the surface film structure. In 1965, Pennwalt Chemical Company in the United States first applied fluorocarbon coatings to meet the requirements of interior and exterior aluminum coating for high-grade buildings. The wide choice of colors, solemn appearance of the United States, and durability have added luster to many magnificent curtain wall buildings around the world. The coating manufacturer's guarantee for the service life of the coating starts from 10 years, 15 years to more than 20 years. American research institutions have tested and compared fluorocarbon coatings, super coatings and general coatings. The samples of the coatings were exposed to hot sunlight in Florida, the United States, and exposed to the harsh environment of wet and salty air for 12 years, which actually proved that the stability and durability of fluorocarbon coatings were 30 percent and 80 percent higher than the other two coatings. Fluorocarbon coatings guarantee the use of all kinds of harsh environment.
Especially suitable for indoor and outdoor decoration in public places, commercial chain, exhibition and advertising decoration and display.
Four, the application of color coated aluminum coil
Color coated aluminum coil has a rich color range, whether it is for residential, large commercial outlets or large exhibition centers, color coated aluminum coil can add color. Good plasticity and machining properties make it an ideal material for all kinds of architectural modeling. Colour-coated aluminium rolls have provided architects, designers and homeowners with colour Spaces to achieve personalised exteriors and ceilings, as well as being the ideal material for building shapes. Whether it is a multifunctional large building or a unique and creative new building, the colored aluminum coil can always meet the different requirements of modern and classical architectural styles, and make the building colorful. Products in electronic appliances, meters, lighting, packaging, home decoration and many other fields have been applied.
Products are widely used in construction (aluminum plastic board, aluminum honeycomb, roof wave board, fireproof veneer panel, aluminum ceiling, shutter, rolling shutter door, garage door, awning, gutter), electronic appliances (computer cases, electrical panels), lighting, furniture, solar reflector, air conditioning duct, etc.
