The surface coating of aluminum alloy doors and windows protects the surface of aluminum alloy profiles, mainly including oxide film, electrophoretic painting, powder coating, and fluorocarbon spraying. There are also wood grain transfer based on powder coating. Deal with more types of colors. Due to different surface treatment methods, the cost of coating thickness gauges is different. Therefore, what kind of surface coating should be selected should be based on the climatic conditions in the location of the building, the use of site, building grades, and economic conditions. . The following small series introduces aluminum alloy selection standards and types of aluminum alloy doors and windows. Aluminum Alloy Selection Criteria 1, the use of materials The main materials for aluminum doors and windows generally include three aspects: aluminum profiles, glass, and hardware. When the owners purchase products, they often pay more attention to the thickness of aluminum profiles and glass, while the requirements for hardware are not very high. This is not comprehensive. In fact, the country has a certain standard for aluminum alloy doors and windows. High-quality aluminum alloy doors and windows used in aluminum, its thickness, strength and oxide film can generally meet the national standards, such as national requirements: aluminum alloy doors and windows of aluminum wall thickness should not be less than 1.2mm, oxide film The thickness should reach 10 microns. Tempered glass is better than ordinary glass. If the security of doors and windows and durability can be considered, stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum accessories, and the best selection of the use of POM material pulley Because such products have higher strength and wear resistance, they are smooth during use and are not easily damaged. You know, the door and window damage is usually started from the door and window accessories! 2, processing With good materials, the next step is the processing of doors and windows. As the technical content of aluminum alloy doors and windows is not high, the degree of mechanization is not high at present, most of them also rely on the manual operation of the installation workers, which requires the operator to have a good sense of product quality. It is very important to enhance the proficiency and product awareness of operators in the production process. High-quality aluminum alloy doors and windows, fine processing, smooth tangent, the same angle (main frame material is usually 45 degrees or 90 degrees), in the splicing process should not appear more obvious gaps, good sealing performance, smooth switch. Inferior quality aluminum alloy doors and windows, especially aluminum alloy outdoor window products, will cause sealing problems if they are not processed properly. Not only will air leakage leak, but under strong winds and large external forces, the glass will burst and fall off. The owner caused a loss of property and even hurt the person. 3, appearance Owners choose aluminum alloy doors and windows products, usually pay attention to the appearance of the product and glass decorative patterns, but often despise the composite film on the surface of aluminum alloy doors and windows, this composite film is formed by artificial oxide film coloring, with corrosion resistance, wear resistance Loss, high gloss, but also has a certain degree of fire protection, so when you buy aluminum alloy doors and windows products to compare more similar products. The art of glasswork varies from person to person, and different owners choose according to their own preferences. 4, price As the price of aluminum alloy doors and windows is directly related to the price of aluminum ingots, the price of aluminum alloy doors and windows in a certain period is relatively stable. Under normal circumstances, the price of high quality aluminum alloy is lower than that of inferior aluminum alloys. Door and window products must be 30% higher. Inferior quality aluminum alloy doors and windows usually use recycled aluminium extrusions containing a lot of impurities. The aluminum profiles used have wall thicknesses of only 0.6-0.8 mm, both in terms of tensile strength and yield. Below the relevant national regulations, such aluminum alloy doors and windows, especially aluminum alloy outdoor windows, are not safe. Therefore, when purchasing products, the owner must not take any cheap measures and despise the personal safety of himself and others. Aluminum alloy doors and windows 1, wire glass By using the calendering method, a metal plate or a metal mesh embedded in a glass plate is used to fight against the plate glass. When it is impacted, it will only form radial cracks and will not break into people. Therefore, it is mostly used in high-rise buildings and oscillating. Strong factory building. 2, frosted glass It is an ordinary flat glass matte processed. The general thickness is more than 9mm, with the thickness of 5, 6mm mostly, and the frosted glass is generally tempered. 3, laminated glass Laminated glass is generally composed of two layers of ordinary flat glass (which can also be tempered glass or other special glass) and an organic glue layer between the glass. When damaged, the debris still adheres to the adhesive layer, avoiding damage to the human body caused by debris splashing. Mostly used for renovation projects with safety requirements. 4, tempered glass It is a type of pre-tipped glass made of ordinary flat glass. Tempered glass is not easily broken compared to ordinary flat glass, the strength is several times that of the latter, the tensile strength is more than three times that of the latter, and the impact resistance is more than five times that of the latter. 5, embossed glass It is a platen glass made by calendering. Its greatest feature is the opaque light transmission, which is used in many fields such as special engineering projects. 6, hot bending glass The flat glass is heated and softened in the mold, and then the annealed curved glass is formed. The frequency of appearance in some advanced decoration is getting higher and higher, need to be booked, there is no spot. 7, sandblasted glass The performance is basically similar to the frosted glass, but the difference is that the modified sand is sandblasted. Because the two are visually identical, many owners and even decoration professionals have confused them. 8, insulating glass Insulating glass uses glue bonding method to keep two pieces of glass at regular intervals. In the interval, it is dry air, sealed around it, and has good airtightness. It is mainly used in doors and windows and renovation projects that require sound insulation. Editor's summary: The selection criteria for aluminum alloys and types of aluminum alloy doors and windows are introduced here, and we hope to help everyone.
