[China Glass Network] Now many home decoration will choose aluminum alloy doors and windows to decorate the house, but many homeowners do not understand how to identify the quality of aluminum alloy doors and windows, then how to identify the quality of the installed doors and windows What? When you buy, how do you buy a good door and window? 1. The installed aluminum alloy doors and windows should be closed tightly and the gap should be even; the deviation between the door and window fan and the frame or the parallelism of the adjacent side of the adjacent fan should not exceed 2 mm. Open and flexible, easy to use. 2. Sliding the doors and windows, see if the glide path is installed flat, be careful not to have unevenness, and gently push the doors and windows, and slide freely. 3. The vertical frame and horizontal frame of the aluminum alloy window of the balcony must be firmly fixed on the balcony railing and the top of the balcony. Generally, it is fixed in the concrete by nails or rivets, and the angled steel is used for reinforcement when fixing. It can't be fixed on the brick wall, and it can't be fixed by the top and bottom of the wooden wedge instead of the nail gun. The gap between the upper glide path and the top guardrail should be filled with cement mortar to prevent rainwater from entering the room. 4. The wall thickness of the aluminum alloy window profile should not be less than 1.4 mm, and the wall thickness of the door profile should not be less than 2 mm. The thickness of the joint between the aluminum alloy door and window frame and the wall shall not be less than 1.5 mm. Aluminum alloy window purchase strategy experts teach you to be a smart consumer Buy first to understand the classification and advantages of aluminum alloy windows With the improvement of social living standards and the rise of craftsmanship, aluminum alloy windows are no longer products without styles. A variety of aluminum alloy windows have appeared on the market and are widely used in home decoration due to their decorative nature. Consumers must choose a high-quality aluminum alloy window, first of all need to have a certain understanding of it. Part1: Purchase first to understand the classification and advantages of aluminum alloy windows The aluminum alloy window is a product that replaces the steel window at the beginning. The aluminum alloy extruded profile is made of frame, 梃, and fan material. The ordinary aluminum alloy sliding window is made of aluminum alloy as the main material, and the sealing and sound insulation effects are better than the steel window. It is also easier to process than pure wooden windows and steel windows. 1, aluminum alloy window classification Classified by opening method: aluminum alloy window can be divided into aluminum alloy casement window (inside open and outer open), aluminum alloy sliding window, aluminum alloy hanging window (overhang, middle overhang, underhang), aluminum Alloy fixed window. Aluminum alloy windows with different opening and closing methods have their own advantages and disadvantages, and are suitable for different spaces. Consumers can choose according to actual conditions. Classified by profile: Aluminum alloy windows can be mainly divided into ordinary aluminum alloy windows and broken bridge aluminum alloys. The broken aluminum alloy window is an improved window introduced on the basis of ordinary aluminum alloy windows to improve the insulation performance of the window. The aluminum alloy profile is divided into inner and outer parts by reinforced nylon spacers to block the heat conduction of aluminum. The aluminum alloy window of the broken bridge has excellent heat insulation, which completely solves the problem that the ordinary aluminum alloy window has fast heat conduction and poor heat preservation. 2, the advantages of aluminum alloy window Compared with other material windows, the big disadvantage of aluminum alloy is that conduction heat dissipation is fast. However, aluminum alloy windows also have many advantages to choose from. The aluminum alloy window is made of aluminum, with light weight and high strength, and the density is only l/3 of the steel. The aluminum alloy window has good sealing performance. The sealing performance directly affects the function of the window and the consumption of energy. The sealing performance includes four aspects: airtightness, watertightness, heat insulation and sound insulation. The airtightness, watertightness and sound insulation of the aluminum alloy window are better. The aluminum alloy window has good durability and is easy to use and maintain. The aluminum alloy window is not rusted, fading, non-shedding, almost no maintenance, and the spare parts have a very long service life. The aluminum alloy window has a good decorative effect. The surface of the aluminum alloy window has an artificial oxide film and is colored to form a composite film layer, which not only has corrosion resistance and wear resistance, but also has a certain fireproof power, and the gloss is extremely high and the appearance is beautiful. Part2: Optional purchase method based on aluminum alloy window When consumers buy aluminum alloy windows, how to judge the pros and cons of the products. In order to facilitate the selection of products of good quality and reasonable price, you can refer to some of the methods listed below. Look at the material The main materials of aluminum alloy window generally include three aspects: aluminum profile, glass, hardware, aluminum alloy window used for high-quality aluminum alloy window should be no less than 1.2mm, oxide film thickness should reach 10 microns; tempered glass Ordinary glass is better; stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum fittings. Second look at processing High-quality aluminum alloy window, fine processing, smooth tangent, uniform angle (the main frame material is usually 45 degrees or 90 degrees), there should be no obvious gap in the splicing process, the sealing performance is good, the switch is smooth. Inferior aluminum alloy windows, especially aluminum alloy outdoor window products, if processed unqualified, there will be sealing problems, not only leaking wind and rain, but also under the action of strong wind and large external force, the glass will burst and fall off. Look at the appearance There should be no obvious scratches, scratches, bumps and other defects on the surface of the window. The colored surface of adjacent members on the window should not have significant chromatic aberration. There should be no aluminum chips, burrs, oil spots or other stains on the surface of the Xugema door and window. There should be no spilled adhesive at the joint. Four look at performance The performance of aluminum alloy windows usually considers the following aspects: strength, which is reflected in the selection of aluminum alloy window profiles, whether it can withstand ultra-high pressure; air tightness, mainly reflected in the window structure, the inner and outer windows of the window Whether the frame structure is strict, etc.; watertightness, mainly to check whether there is water and leakage in the aluminum alloy window; sound insulation, which mainly depends on the sound insulation effect of the insulating glass and other special soundproof airtight strip structure and opening and closing force, Durability of other window fittings such as opening and closing durability. Five to see the price Under normal circumstances, the price of high-quality aluminum alloy is 30% higher than that of inferior aluminum alloy window products. Inferior aluminum alloy windows usually use aluminum profiles extruded with recycled aluminum containing a large amount of impurities. The aluminum profiles used have a wall thickness of only 0.6- 0.8 mm, whether it is from tensile strength or yield, it is much lower than the national regulations. This kind of aluminum alloy window, especially the aluminum alloy outdoor window is very unsafe, so don’t be cheap and contempt when purchasing. Personal safety for yourself and others. Part3: Installation does not need to look at the aluminum window installation process In the decoration, many owners choose to use aluminum alloy windows. The following will introduce the standard process of aluminum alloy window installation. The general flow of aluminum alloy window installation is: line positioning→ aluminum alloy window water installation → anti-corrosion treatment → aluminum alloy window installation in place → aluminum alloy window fixing → window frame and wall gap treatment → window sash and window glass Installation → installation hardware accessories. 1, line positioning According to the installation position, size and elevation of the window in the design drawing, the window edge is measured according to the center line of the window. In the case of multi-storey or high-rise buildings, the edge of the top window shall prevail, and the edge of the window shall be led down by a line pendant or theodolite, and marked at each layer of the window, and the individual not straight edges shall be chiseled. The horizontal position of the window shall be measured by the horizontal line of the floor indoor +50cm, and the height of the window shall be measured downwards, and the elastic line shall be straightened. 2, aluminum alloy window draping installation Batch water refers to the profile of the upper part of the sash that blocks the infiltration of rainwater into the room. Fix the draping on the aluminum alloy window according to the requirements of the construction drawings, and ensure that the position is correct and the installation is firm. 3, anti-corrosion treatment When the anti-corrosion treatment design of the outer surface of the window frame is required, it shall be treated according to the design requirements. If the design does not require it, it can be coated with anti-corrosion coating or plastic film to protect the cement mortar from direct contact with the aluminum alloy window surface, resulting in electrochemical reaction and corrosion of the aluminum alloy window. When installing an aluminum alloy window, the connecting piece is preferably made of stainless steel. Otherwise, anti-corrosion treatment must be carried out to avoid electrochemical reaction and corrosion of the aluminum alloy window. 4, aluminum alloy window installation in place Install aluminum window frames according to the planned window positioning line. And timely adjust the horizontal, vertical and diagonal length of the window frame to meet the quality standards, and then temporarily fixed with wooden wedges. 5, aluminum alloy window fixing When the iron piece is embedded in the wall, the iron feet of the aluminum alloy window can be directly welded to the pre-embedded iron parts on the wall, and the welding place needs to be rust-proof; when there is no embedded iron piece on the wall When the metal expansion bolts or plastic expansion bolts are used, the iron feet of the aluminum alloy window can be fixed to the wall. 6. Treatment between the gap between the window frame and the wall After the aluminum alloy window is installed and fixed, the concealed project acceptance shall be carried out first. After passing the test, the gap between the window frame and the wall shall be treated in time according to the design requirements. If the design is not required, the elastic insulation material or glass wool felt strips may be used to fill the gaps in layers, and the outer surface is filled with a 5-8 mm deep notch to fill the caulking grease or sealant. 7. Installation of window sash and window glass The sash and window glass shall be installed after the completion of the decoration of the wall surface of the opening. After the sliding window is installed and fixed, the glass sash with the glass is placed into the sliding slot of the frame to adjust the gap with the fan. Part4: Beautiful maintenance by maintenance of aluminum alloy window daily maintenance Nowadays, many households are equipped with aluminum alloy windows. The windows are the "eyes" of the house and play a very important role. In order to extend the service life and maintain the beauty of the aluminum alloy windows, the Xugema doors and windows need to pay attention to the maintenance. 1. Push and pull gently when using During the use of aluminum alloy window, it should be lightly pushed and pulled gently, push and pull to go with the flow; if it is difficult to force it, it should be eliminated first. Ash accumulation, deformation is the main reason for the difficulty of pushing and pulling aluminum alloy windows, to keep the door frame clean, especially the cleaning of the groove. A vacuum cleaner can be used to remove the ash from the inside of the tank and the door. 2, do not use strong acid and alkali cleaners After the rainy day, the raindrops of the glass and window frame should be timely, paying special attention to the water in the chute. The chute is used for a long time, the friction is increased, and a little oil or a layer of fire wax oil can be added. Aluminum alloy windows can be wiped with a soft cloth dampened with water or a neutral detergent. Do not use ordinary soap and detergent, or use strong acid and alkali cleaners such as decontamination powder and toilet cleaner. 3, timely repair and replacement of the seal Sealing tops and glass glue are the key to ensure aluminum alloy window sealing, heat preservation and waterproofing. If it falls off, it should be repaired and replaced in time. 4. Regularly check if the parts are damaged. Always check the tightening bolts, positioning shafts, wind braces, floor springs, etc., and replace damaged parts of the aluminum alloy window in time. Regularly add lubricant to keep it clean and flexible. 5. Check if the joint between the window frame and the wall is loose. Frequently check the joints of the aluminum alloy window frame wall. If it is loose for a long time, it will easily deform the whole frame, so that the window cannot be closed and sealed. Therefore, the loose screw at the joint should be tightened immediately. If the base of the screw is loose, apply a small amount of cement to seal with a strong epoxy glue.
