Glue is an intermediate that connects two materials. It mostly appears as a water agent. It belongs to the fine chemical category and has a wide variety of types, mainly based on the classification of adhesive materials, physical forms, hardening methods and materials to be adhered. Glue does not exist independently, it must be applied between two objects to play a bonding role. The common ones are instant glue (common 502α-ethyl cyanoacrylate strong instant adhesive), epoxy resin bonding, anaerobic glue, UV glue (ultraviolet light curing), hot melt adhesive, pressure sensitive Glue, latex, etc. The following are the glues used on several doors and windows of the sealing strip manufacturer
Ruida Baibang. Household wooden doors and windows: In the process of making wooden doors, the door stops are made with T-shaped grooves, and the matching sealing strips are added to make the door have excellent door sealing and sound insulation functions. Sometimes it is necessary to choose and use rubber, such as natural rubber. (NR) and CR and styrene-butadiene rubber (SBR) three kinds of rubber together or polyethylene (PE), EPDM and NR rubber and plastic together to improve the ozone resistance. Plastic steel doors and windows: door and window sealing strips play an important role in watertightness, airtightness and energy saving in doors and windows. According to the role and use requirements of the sealing strip, the plastic steel door and window sealing strip must have sufficient tensile strength, good elasticity, good temperature resistance and aging resistance, and the cross-sectional structure size must match the plastic steel door and window profile. Nitrile rubber has excellent resistance to fuel oil and aromatic solvents, but it is not resistant to media such as ketones, esters and hydrogen chloride. Therefore, oil-resistant sealing products and nitrile rubber are mainly used. Anti-theft doors and windows: AB glue, rubber glue, 801 super glue, QIS-3003 special strong adhesive and other glues can be used. Generally, door seals are now self-adhesive. First, clean the surface to be pasted to make it clean, smooth, flat and dry. Then measure the height of the doors and windows, according to this height, use scissors to cut off the rubber seal. Peel off a small section of the backing protective paper, install the rubber sealing strip to the correct position and press it tightly, and try to align it with the top edge. Keep peeling off the protective paper on the back so that the rubber sealing strip extends downwards along the frame and keeps pressing it tightly. Be careful not to stretch it. Finally, use the same steps to install the horizontal sealing strip, paying attention to the anastomosis at the corner joints, and there should be no gaps between the connections. Just use some AB glue. You have to wait for the glue to dry, otherwise it is easy to glue the door. You can use glass glue. 502 aluminum alloy glass doors and windows: neoprene glue, EPDM, EPDM adhesive. EPDM sealing strips are generally used on door and window sashes. There are special sealing strip grooves on the layering strips and doors and windows. The main function is to wear the sealing strips on both the layering strip and the inner fan to make the glass and the frame fan closer. , Thus ensuring the air tightness of doors and windows. The installation part of the sealing strip should be flat, not crimped, or stretched. The joint should be less than 1MM. The type of the sealing strip should match. Too big, the pressure strip cannot be pressed in, and too small will make the sealing strip easy to fall off. It is not close to the fan body, there will be gaps. The sealing tape should be non-toxic. Odorless and environmentally friendly special sealing tape. Adhesive door and window sealing strips should use neoprene glue EPDM EPDM adhesive. Car door and window glass: The sealing strips of cars are stuck to the door and door frame with grooves, and generally do not need glue. If you have to use adhesive, you can only choose waterproof and anti-aging adhesives. If 3M glue is used, there is no harm to the car paint, and it does not meet the requirements of not opening glue. It is not easy to open the glue with 502. Instead of using glue, use the automotive professional 3M double-sided adhesive to bond.
At the same time, as the recent research of Kenna shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
