[China Glass Net] Door and window seals are divided into glass seal strips and tops. Seal strips are generally used on door and window sashes. There are special seal strips on the bead and door and window. The main function is to make the glass and frame fan tighter through the strip and the inner fan. The airtightness of doors and windows. The installation part of the sealing strip should be flat, not curled, and should not be stretched. The joint should be less than 1MM. The type of sealing strip should match. If the strip is too pressed, the strip will fall off easily. And the fan is not tight, there will be gaps. Sealant strips should be non-toxic. Odorless environmental protection special sealing strip.
The installation position of the top is generally on the door and window sash, around the frame fan or on the sealing bridge (wind block), and the sealing between the frame and the fan is enhanced. If the top size is too large or the vertical hair is too high, not only the assembly is difficult, but also the resistance of the door and window is increased, especially the initial resistance of the opening and the resistance of the closing position are large. If the specification is too small, the height of the vertical top is not enough to escape from the slot, so that the sealing performance of the (door) window is greatly reduced. The tops are subjected to silicidation, and the quality of the tops is flat and the bottom and vertical are smooth. No bending, no pitting on the bottom plate. bubble. The vertical hair and the bottom plate are firmly bonded, the density is uniform, and it is not easy to lose hair.
Doors and windows have excellent sealing and water tightness, so the sound insulation? Naturally handed to the soundproofing hand - insulating glass. Put two or more pieces of glass through the aluminum alloy spacers (filled with desiccant inside) and add the interval between the corner posts, and put butyl rubber on the four peripheral edges of the glass. Polysulfide; it forms a static, dry gas, and has a vacuum property. Insulating glass is insulated, sealed, frost-proof, dust-proof and sound-proof. A variety of superior performance. Therefore, many users agree. The inside of the excellent insulating glass should be clean. No dust. No moisture.
Good doors and windows are inseparable from production and installation, and the standard of production is essential for high standard doors and windows. Production equipment and processes determine whether the overall performance of the doors and windows is excellent. According to the requirements, the difference between the diagonal lines of plastic steel doors and windows should be controlled within 2 - 3 mm, with strict process parameters and control range, which requires certain production equipment and processes to ensure the quality of the workforce. . Therefore, the street-side workshops and the plastic-steel doors and windows produced by regular manufacturers are simply different. Three-point production, seven-point installation, if you do not pay attention to the installation standard can cause door and window deformation. The thermal coefficient of plastic steel is almost six times that of just. Therefore, the expansion joint must be left between the window frame and the wall to prevent thermal expansion and contraction or slight settlement of the house, so that the door and window are deformed. At the same time, to ensure waterproof. Keep warm. For sound insulation, the expansion joint must be filled with an elastic material and then sealed with a sealant. These materials are expensive and vary in quality. When installing, it is necessary to prevent cut corners and shoddy.
