The sealing strip is a kind of rubber strip that can seal things so that they cannot be opened easily, and has the functions of shock absorption, waterproof, sound insulation, and dustproof fixing. Next, we will mainly introduce the sealing strip around several aspects, such as the classification of the sealing strip, the characteristics of the sealing strip, the selection of the sealing strip material, and how to distinguish the advantages and disadvantages of the sealing strip.

Sealing strip classification

First, according to the different cross-sectional shape, it can be divided into: solid core products, hollow products, metal rubber composite products, etc. Among them, solid core products can have round, square, flat cross-sectional shapes and so on.

Second, according to the different vulcanization methods, it can be divided into: discontinuous vulcanization sealing strip, microwave continuous vulcanization sealing strip, salt bath continuous vulcanization sealing strip, hot air continuous vulcanization sealing strip, etc.

Third, according to the different parts of use, it can be divided into: window glass sealing strip, door sealing strip, door and window sealing strip, mechanical sealing strip, ship sealing strip, decorative strip, molding strip, trunk lid sealing strip, water tank sealing strip , Engine hood sealing strip, emergency door sealing strip, etc. Among them, mechanical sealing strips can also be divided into cabinet sealing strips and container sealing strips.

Sealing characteristics

First, it can have the effect of shock absorption and anti-collision. When there is wind, the entrance door without the sealing and shock-absorbing rubber strips on the side of the door will easily cause a "pop" sound. If the door frame frequently collides in this way, it will cause damage to the door, wall and window. The door side sealing damping strip can well avoid this situation.

Secondly, it can have the effect of airtight silencer. The sound insulation effect of doors and windows installed in many bedrooms is not satisfactory.

Third, it can play a decorative and beautifying effect. Some doors need to be nailed and fastened between the door frame and the wall during installation. Sealing strips can be used to cover the position of the nail holes.

Fourth, you can make up later. Due to factors such as climatic environment and material selection, the door often shrinks and swells slightly after installation. If the door side sealing and shock-absorbing rubber strips with good material and reasonable structure design are used, the automatic expansion and contraction function can be fully exerted and the door deformation can be avoided.
