The main materials of doors and windows generally include three aspects: outer frame profiles, glass and hardware parts. Owners in the purchase of products, often pay more attention to the profile and glass thickness, and the hardware requirements are not very high, this is not comprehensive.In fact, the state requirements for doors and windows is a certain standard, the quality of the doors and windows for the profiles, the thickness, strength and oxide film can generally meet the national standards. While the glass is ordinary glass is better, if considering the safety and durability of the doors and windows, stainless steel hardware accessories (such as screw, hinge etc.) than aluminum parts, you know, usually start from the doors and windows accessories Yo is damaged doors and windows!2, processingWith good materials, the next step is the processing of doors and windows. Due to the technical content of doors and windows is not high, mechanization is not high, most rely on the manual operation of the installation workers, which requires operators to have a good product quality awareness.It is very important to strengthen the proficiency and product awareness of operators in the production process. High quality doors and windows processing fine, tangent smooth, angle consistent, in the stitching process should not appear obvious gap, sealing performance is good, switch smooth. If the processing is not qualified, will be sealed in nature, not only air leaks, but also in strong winds and large under the action of external force, the glass will appear crack, fall off phenomenon, resulting in the loss of property and even wounding phenomenon to the owner.3, appearanceOwners buy doors and windows products, usually pay much attention to the appearance of the product and glass decorative pattern, and often belittles the film on the surface of the glass doors and windows, glass doors and windows are even using toughened glass, also has the possibility of the explosion, after the window glass film, is to prevent the harmful UV rays into the interior, to insulation, safety. Safety protection is greatly improved. So in the choice of doors and windows products to compare more similar products.4, the priceBecause the market price on the window level and the price of the material level has a direct correlation, but generally in a certain period of time the price performance of windows is relatively stable, in general, in the same grade, quality doors and windows price is 30% higher than that of inferior windows and doors, doors and windows usually contains a lot of impurities of inferior quality squeeze or recast into either from tensile strength or yield strength are greatly reduced, the window is not safe, so the owners in the purchase of products do not a cheap but ignores the personal safety of yourself and others.5, performanceThe doors and windows performance due to the use of different scope and focus are different, but generally should consider the following aspects: strength, which is mainly reflected in the window profile material, is able to withstand high pressure; air tightness, mainly reflected in the window structure, doors and windows of the inner fan and frame structure is tight, close doors and windows.

1, in cleaning aluminum doors and windows, do not step on the aluminum frame, do not pull the box as a support, so easy to wear doors and windows or accidents.Section 2, clean aluminum windows and doors with soft cloth dipped in water or neutral detergent, soap and washing powder do not use detergent, not detergent, toilet washing and other fine strong acid, because it will corrode the surface of profile.3, doors and windows can be stained with vinegar water wipe clean. If the glass is stained with oil, the glass can be sprayed completely with detergent, and then cling to the film, so that the solidified oil softening, after ten minutes, tear off the plastic film, and then wipe with a wet cloth.4. Clean the screen, gently rinse with soft water pipes and showers to remove cobwebs, dust, and other con***inants that stick to it. Next, prepare some soapy water to stick on the short hair brush, and then gently scrub on the screen to make sure that the screen has enough soap foam, and finally rinse and wait for air drying.5, clean push trough can use vacuum cleaner or small brush to remove groove and door sealing top ash deposition.6, check the door and window frame joints, tighten the bolts, add the lubricating oil to keep clean, such as screw loose footing, application of epoxy glue transfer a small amount of cement.How！ Is everybody here at Get?

The installation of doors and windows is a important step in the process of measuring the size of windows and doors, is the priority among priorities in the installation process, accurately determine the engineering quality and progress of the size, there is a proverb "three points and the manufacturing industry, the installation of seven", which shows the importance of the installation of doors and windows. Whether the process flow of the installation process is smooth or not determines the success or failure of the project. The process flow of the installation of doors and windows is described as follows:First, door and window factory inspectionInspection items:The inspection before the finished product is checked by the main items and the general items of the finished doors and windows, including the connection of components, the opening and closing of the fans, the assembly quality of the doors and windows, the dimensions of the doors and windows, and the surface quality.

Packaging should use protective film uniformly adhered to profiles.1 storage and storage of finished products at construction site1) doors and windows in the field of transportation process should prevent severe collision and mutual wear, strictly prohibited pry. For lifting, should choose strong smooth outer doors and windows in the focal point, and in the window surface soft pad material, not in the box fan is inserted into the lifting beam.2) doors and windows should be placed in the ventilation, rain, clean and smooth place, is strictly prohibited to contact with corrosive substances, but also should prevent human factors damage.3) doors and windows should not touch the ground directly, and the bottom should be padded with the thickness of not less than 30mm. Door and window frame fan should stand upright, angle is not less than 70 degrees, and should have anti dumping measures. Different sizes of doors and windows should not be stacked.4) the environmental temperature of finished product storage should be less than 50 degrees, and the distance from heat source is not less than 2m. Doors and windows stored at a temperature lower than 10 degrees should be installed at room temperature for 24 hours and then installed.Three: installation process (should comply with GB/T8478-2008, JGJ103-96)Requirements for walls and openingsDoors and windows must be checked at the base or base level before they can be carried out.The installation must adopt the method of reserved openings, and the size of doors and windows should conform to the relevant provisions in GB5824-86. For the same type of doors and windows, the left and right sides of the upper and lower sides and the upper and lower openings of the adjacent openings should be on the same horizontal line or vertical line. And the window frame and wall gap is not too small, should be able to fill foaming agent is appropriate. The allowable deviation of the width and height of the tunnel shall be in accordance with the relevant provisions of table 1.1.Door and window installation should be done after the wet work of the wall is finished and solidified.1) determination of installation position datum line(1). The baseline for the width of the top line, line by building a door hanging tag, window width datum line for door opening line.(2) the hole of the bottom ash should be taken as the horizontal datum line with the height of the entrance hole. For the larger scale project, the unified horizontal datum line should be taken as the standard(3) the datum line of the wall thickness is determined according to the design or construction requirements.2) door and window frame and wall fixing method(1) the expansion bolt method can be used to fix the door frame and the wall. The expansion bolt has high strength and high stability, but it is not suitable for small window type. 3) installation stepsThe door window frame into the hole (the expansion bolt method should be pre drilled hole in the window frame installation), and with wedge alignment positioning. According to the requirements of the datum line, the horizontal, vertical, right angle and uniform gap of the window frame are adjusted and adjusted by the horizontal ruler in turn. The frame below the horizontal level is the datum, the verticality is based on the border, and the right angle is based on the diagonal line. It is forbidden to use hard hammer to frame when adjusting.(2). The expansion bolt through the window: the reserved installation hole drilling bottom hole in the corresponding position of the bottom wall, than the bolt is screwed into the depth slightly deeper, screwed into the expansion bolt. When the level, verticality and right angle of the confirmation frame meet the requirements, the bolt is tightened, and the supporting block between the wall and the frame of the expansion bolt is pointed out, and the supporting block does not need to be removed after installation. Expansion hole should be sealed with sealant to prevent leakage.(3) filled with PU foaming agent and other elastic filling material. Fill the foaming agent before cleaning the dust of the hole, etc., before the PU foaming agent is not completely solidified before the chips can be used to repair light. The foaming agent filling after removing the wedge to find replacement agent.(4) for special projects, the silicone sealant should be applied to the joint of the wall and the frame after the wet work is solidified.Vi. installed doors, windows and accessories, according to different forms of doors and windows installation.Table 1.1 allowable deviation of hole size         洞口尺寸允许偏差<2.5m2.5-5.0m>5.0m水泥墙面±10mm±15mm±20mm已粉刷墙面±5mm±10mm±15mm 表1.2     塑钢安装*小预留间隙（未考虑墙面装饰）        窗边长预留间隙<1m1~2m2~3m白色型材10mm10mm15mm彩色型材10mm15mm20mm3) installation of fixed glass.(1) the glass pad should be installed around the glass when the glass is loaded. The size, size and quantity of the cushion block should meet the requirements. The opening fan of flat window needs to be blocked with glass pad block, so as to prevent sagging when opening.(2) glass size should meet the requirements, to ensure that each side lap 5~7mm, glass and window frame can not directly contact, before and after clearance 5mm or so, filled with rubber strips.(3) the glass side applies a complete and continuous adhesive strip, and the four sides of the interface should be butted with 45 degrees. The sealing strip on both sides of the glass should be tightly connected without any groove or edge pressing, and the rubber strip should be moderately tight.Casement window, fixed window glass strip after the assembly should be firmly, butt gap is not more than 0.2mm, roughness less than 0.2mm (check with the feeler), and should not be too long.(4) casement doors and windows are equipped with hardwareThe size and location of the hardware should meet the requirements of the drawing.Installation should be firm and reliable, installation screws are not allowed to slip phenomenon.After the hardware is installed, the fan is opened and closed flexibly, and there is no sticking phenomenon. The use function meets the requirement of use.The overlap fit of the frame fan should be uniform, and the size deviation of the fitting should be + 1mm.(5) the glue inside and outside wall glue should be uniform, smooth, free of plastic wings, continuous and beautiful, the thickness of the adhesive is not less than 3mm, the width is not narrower than 8mm.The window frame under all frame mounting holes, all seams, open fan position, transom and frame connection should hit the glass glue, to prevent water penetration.Four: quality acceptance specificationBefore installation, operators should check whether the door and window profiles and glass surface have scratches, the door and window frame fan is flat and vertical, diagonal tolerance is not less than 2.0mm, expansion bolt is loose, etc..The operators strictly carry out the installation operation according to the process requirements. After the completion of each process, the self inspection is carried out immediately, and the unqualified items found in the self inspection are corrected immediately by the team until they are all qualified.When foaming agent fills the gap between window frame and wall, water treatment should be carried out first, and dust in the gap should be treated cleanly. Foaming should ensure uniform filling and fullness.Check whether the inner and outer wall glue is flat and vertical, the width should be uniform and smooth, the thickness of the glue is not less than 3mm, the width is not narrower than 8mm.The window frame under all frame mounting holes, all seams, open fan position, transom and frame connection should hit the glass glue, to prevent water penetration.Doors and windows components should be firmly connected, no missing parts, not loose. The accessories of doors and windows should meet the requirements of the contract quality standard. There is no flying edge, burrs, complete plating of metal parts, no shedding, corrosion and other phenomena. The coloring surfaces of adjacent components of doors and windows should be basically the same, with no obvious color difference. Check all parts of the window accessories are complete, the location is correct, the installation is firm, to ensure that meet the use requirements, doors and windows and accessories assembly should be opened smoothly, there is no impedance phenomenon.Five: after sale serviceIn the warranty period, receive maintenance notice, 24 hours in place maintenance service. The owner of the relevant product problems, Party B within 4 hours to reply.Six: prevention measures of common quality problemsIn recent years, the peripheral Aluminum Alloy doors and windows are used more and more widely. Aluminum Alloy doors and windows of the firmness and beautiful appearance is obvious to people, but for the problem of leakage Aluminum Alloy doors and windows has been in existence.1. main leakage: water seepage inside the window and window stitching appeared leaking, seepage, leakage, in parts of the sash frame part and the corner wall and group form several common situations such as water seepage.2 the main causes of leakage and preventive measures:The main reason for water leakage in the 2.1 windows is that there is a gap between the glue strip or the glass glue on the side of the window. If this is the glue, to the window at the lower part of the strip cut, use glass glue instead of glue. If the outside is already glass glue, check the glue quality of the glass adhesive and rally the glass glue.2.2 the main reason for windows joint leakage is seam leakage, it will be in the window and window mosaic, put the card on the material, evenly coated on the transparent glass glue in stitching material, then stitching, stitching is completed, and then coated with a layer of glass glue in the gap at.2.3 the main reason for the leakage in the window sash is that the sealing tape of the window sash does not play the role of blocking rain. Check the amount of overlap of the window sash and whether the sealing strip is suitable and the drainage hole at the window sash is reasonable. Adding a water repellent glue strip to the window frame can effectively solve the leakage problem of the window sash.2.4 middle joints mainly due to leakage in the assembly process, no glue applied to the corner, to form a gap appears in the corner when leaking, so must take the angle or joints to smear a good corner glue. In this case, glue at the seam of the form can solve this problem.2.5 forms and wall cracks appear leakage. This is the most prominent windows leaking leaks, is common, the most difficult to deal with the phenomenon, the main reason is the installation of doors and windows around the foam is not tight. Civil window finishes the leaking process is not appropriate. The quality of sealant is poor, or the sealant does not match the exterior wall. The glue is discontinuous, not in place, and seriously shrinking. Is the main reason for the form and the wall crack appeared leaking.Now the building generally in the wall of the external insulation board, doors and windows directly and insulation board contact, this is also a window and wall gap leakage is one of the main reasons. The way to deal with this problem is to add a subframe to the aluminum alloy doors and windows, so that the doors and windows leave the insulation board, and also prevent the insulation board from blocking the drainage hole. In addition, the window is well designed double channel mouth, the mouth of the mouth should have a slope, greater than 10 degrees.To sum up, the doors and windows installation will be a qualified door and window through the work

 Plastic steel doors and windows of the gap filled with dust? You're wrong with the wire ball, you're wrong! You can wipe it thoroughly with vinegar!Egg shell turns small pot!

1, if a large area, go to the hardware store to buy a putty knife, sharpen it, and then carefully scraped on the line! If the area is small, you can use a knife or a knife gently scraping, or with banana water, gently wipe several times, the edge will be turned off, and then you can use a knife to cut, you can leave no traces.2, when it's a little harder, take a useless credit card, or membership card and so on, along the glass surface, slowly scraping, will scrape off. Because the credit card is soft, not easy to hurt the surface of the glass, with a coin can also, but the metal must be careful.3, if after scraping, the glass will have a layer of grease, and then cotton cloth dipped in soda or pine perfume, there will be no wipe.4, you can use brush brush wire brush, especially good scratch.5, if there is no tear, with a hair dryer to transfer heat, self-adhesive paper edge blowing edge tear, so basically do not leave glue, even if there is little Fengyoujing chemical reaction can be dropped. If it is torn off leaving large plastic, with pine fragrance with a towel (or paint thinner paint in hardware or grocery where there are sold less than five yuan a bottle of glue in a circle wipe).How do you wash your hands with glass glue?1, cotton yarn of kerosene or gasoline, clean, and then use soap or washing powder to wash, surface. ,2, the paper wipe large, then the surface or washing powder with a little water, knead, full, clean.3, wipe the large piece, fully dry, and then rub it. After the solvent is volatilized, the glass film is formed.How do you wash the glass glue on your clothes?If attached to the clothes, you can consider the use of brush brush, if you still can not remove the glass glue, it is necessary to consider the banana water.How to wash the glass glue on the floor?Glass glue on the floor, depending on the floor, choose different methods. If it is tile material, generally removed relatively simple, with a knife slowly scraping away the fixed glass glue on it. If the board material, sponge soaked in boiling water into the heat, the water thrown dry, repeated wiping several times, glass glue will often erase.How to wash the glass glue on the tile?1, go to the supermarket to buy a bottle of household cleaning agent (lampblack machine), and then spray in the glass glue place, wait a few minutes, wipe with a cloth will be clean.2, the cured glass glue, fewer words can be directly with a sharp blade, much of it can wipe paint trowel or grab sub scrape, convenient quickly.3, can get rid of blade with banana + water, pure water is colorless and transparent banana volatile liquid, have a strong smell of bananas, slightly soluble in water, soluble in various organic solvents, flammable, mainly used as paint solvents and thinners.4, can use passenger protection forest degreaser, developed specifically for home users of a cleaning agent, can be used for ceramic tile, stone, glass surface cleaning, can effectively remove the surface of the paint, glue, tape and other residues. Colorless and odorless, not volatile.
