Door and window sealing strips are commonly black rubber objects, which are commonly found at the edges of doors and windows, and are elastic strip-shaped or rod-shaped materials on the combined parts of glass and bead, glass and frame fan, frame and fan, fan and fan. It can block water, wind, sound, etc., and temperature, and can prevent mechanical damage caused by metal collision, so it can be sealed, sound insulation, heat insulation and shock absorption. Therefore, as a key part of doors and windows, it must have sufficient tensile strength, good elasticity, good temperature resistance and aging resistance, so as to ensure a good use experience and a comfortable home experience of doors and windows. Therefore, its section

The sealing strip market is mainly made of ethylene propylene diene monomer (EPDM) rubber, rubber and plastic. According to its use, it can be divided into automobile sealing strips, mechanical sealing strips, door and window sealing strips and so on. Door and window sealing strips are classified into plastic steel door and window sealing strips, aluminum alloy door and window sealing strips, wooden door sealing strips, cold storage door sealing strips, grain depot door sealing strips, flame retardant door and window sealing strips, glass sealing strips, automatic revolving door sealing strips, building door sealing strips, curtain wall sealing strips, etc. The characteristics of the door and window sealing strip are the new generation of doors and windows that have been widely used in recent years. It has better corrosion resistance and weather resistance than ordinary door and window sealing strips.

A tubular rubber product used to transport gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layer and skeleton layer. The material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. The inner and outer rubber layer of the general hose is made of natural rubber, styrene butadiene rubber or butadiene rubber; oil-resistant hose is made of chloroprene rubber and nitrile rubber; acid and alkali resistant, high temperature resistant hose is made of ethylene propylene rubber, fluorine rubber or silicone rubber. In recent years, thermoplastic rubbers such as thermoplastic urethane rubbers, polyester rubbers and the like have come to be used. Because of the advantages of easy bending, buffering, light weight and easy installation and use, the hose has a wide range of uses,

The sealing strip is mainly used for plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decorative doors and windows. The following is a detailed introduction to all door and window sealing strips: door and window sealing strips, glass sealing strips, and door leaf cover sealing strips. The sealing strips are used for sealing between glass and glass doors and frames, and door leaf cover sealing strips. The sealing strips are mainly used for doors and door frames, and the sealing of kitchen rooms is mainly used for sealing between frames and doors. Sealing strip plays an important role in the waterproof, sealing and energy saving of plastic steel doors and windows and broken bridge aluminum doors and windows, wood doors and windows, sound insulation, dustproof, antifreeze, warm. It must have strong tensile strength, good elasticity, and also need good

Key points of quality control of sealing strip: (1) The sealing strip can be directly installed on the doors and windows in the factory when producing doors and windows, but when the doors and windows are transported, attention must be paid to prevent warping and deformation. (2) the selection of the variety and specification of the sealing strip should be matched with the type of door and window, the width of the gap and the part used, otherwise the expected effect will not be achieved. (3) The sealing strip for the flat door window should be attached to the pressure surface of the door and window seam, and should not be attached to the shear surface, otherwise the service life of the sealing strip will be greatly shortened. (4) Before pasting the sealing strip, the joint of the door and window should be cleaned in advance, free of dust and dirt, and clean and dry. (5)
