in wood doors and windows, sealant strips play an important role in waterproof, sealing and energy saving, sound insulation, dust prevention, antifreeze and warmth preservation. It must have strong tensile strength, good elasticity, and better thermal endurance and aging resistance. In order to ensure the fastening of the Strip and the profile, the section structure size of the strip must match the plastic steel door window profile. Sealant strip is generally used for flat doors and windows, hanging windows, folding doors and windows.
1. Classification of door and window rubber steal strip
door and window rubber steal strip is divided into glass sealant strip and wool tops. Sealing strip adhesive strip is generally used on doors and windows Fans. There are special sealing strips and slots on the layering and doors and windows. The main function is to wear sealing strips on the layering and inner fan to make the glass and frame fans closer, so as to ensure the air tightness of doors and windows. The installation part of sealing strip adhesive strip should be flat, not curl, not stretch, the joint should be less than 1MM, the model of sealant strip should match, too large will make the layering not press in, too small will make sealing strip adhesive strip easy to fall off, the glass Japanese fan is not tight, and there will be gaps. Sealant strip should be non-toxic. Odorless and environmentally friendly special sealant strip.
2. Wool tops installation parts
the installation part of wool tops is generally on the door and window fan, around the frame fan or on the sealed Bridge (windshield block) to enhance the seal between the frame and the fan. Wool tops the specification is too large or the vertical hair is too high, which not only makes it difficult to assemble, but also increases the moving resistance of doors and windows, especially the initial resistance of opening and closing. The specification is too small, and the vertical height of wool tops is not easy to get out of the groove, which greatly reduces the sealing performance of the (door) window. Wool tops need to be silicified. The qualified wool tops has a straight surface and smooth bottom plate and vertical hair. No bending, no pitting on the bottom plate. Bubbles. The vertical hair is firmly bonded to the bottom plate, the density is uniform, and it is not easy to shed hair.
3. Excellent sealing and watertightness
doors and windows have excellent sealing and watertightness. What about sound insulation? Naturally, give it to the sound insulation expert-hollow glass. Two or more pieces of glass are separated by aluminum alloy barrier (filled with desiccant) and corner columns, and butyl rubber is applied to all edges of the glass. Polysulfide gum; Make it form static, dry gas, and have the performance of vacuum. Insulating Glass has heat insulation, sealing, frost prevention, dust prevention and sound insulation, etc. A variety of superior performance. Therefore, many users agree. The inside of the excellent hollow glass should be clean. No dust. No moisture.
Good doors and windows cannot be separated from manufacture and installation. Whether the standard of manufacture is or not is essential for high-standard doors and windows. Production equipment and technology determine whether the overall performance of doors and windows is excellent. Three-point production and seven-point installation. If you do not pay attention to the installation standard, the doors and windows can be deformed. Expansion joints must be left between the window frame and the wall to prevent thermal expansion and contraction or slight settlement of the House, which will deform the doors and windows. At the same time, to ensure waterproof. Heat preservation. Sound insulation performance, the expansion joint must be filled with elastic material, and then sealed with sealant. The price of these materials is relatively high, and the quality varies greatly. During installation, it is necessary to prevent jerry-building and shoddy.
