Aluminum alloy material good or bad method
[China Aluminum Industry Network] Judging the advantages and disadvantages of aluminum alloy doors and windows, whether it is aluminum alloy interior doors (including partition doors) or aluminum alloy windows, in the purchase of such products must pay attention to the following points:
Front: materials
Aluminum alloy doors and windows of the main materials generally include three aspects: aluminum, glass, hardware, the owners in the purchase of products, often pay more attention to the thickness of aluminum and glass, but the hardware requirements 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 the relevant national regulations require: 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 pulleys are better choice of products using POM materials. 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!
Second: 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.
Third: Appearance
Owners choose aluminum alloy doors and windows products, usually pay attention to the appearance of the product and glass decorative patterns, and often despise the composite film on the surface of aluminum alloy doors and windows, this composite film is formed by the artificial oxide film color, 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.
Fourth: 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 are 30% higher. Inferior quality aluminum alloy doors and windows usually use recycled aluminium extrusions containing large amounts of impurities. The aluminum profiles used have wall thickness 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 despise the personal safety of himself and others by taking advantage of cheaper prices.
Fifth: Performance
The performance of aluminum alloy doors and windows is different depending on the scope of use, but usually consider the following aspects: strength, which is mainly reflected in the choice of aluminum alloy doors and windows profiles, whether he can withstand high pressure; Sexuality is mainly reflected in the structure of doors and windows, whether the internal fan and frame structure of doors and windows is tight, whether the aluminum alloy outdoor window is tight and airtight, and the watertightness is mainly to check whether the aluminum alloy doors and windows have the phenomenon of water accumulation and leakage; Mainly depends on the sound insulation effect of insulating glass and other special sound-proof airtight structure and the durability of other door and window accessories such as opening and closing force, heat insulation, durability of nylon guide wheel, and durability of opening and closing lock.
