High quality properties of glass seals

[China Glass Net] Many sealing strips contain steel strips, such as car door frame seals, front and rear cover seals, automobile interior and exterior water strips, and u-shaped decorative strips. The steel strip plays a large role in the sealing strip. In order to assemble the guide groove, the bottom of the guide groove section should be designed with corresponding structure, which is easy to install and can be attached to the steel guide groove by the elasticity of the sealing strip itself to prevent It is pulled out; finally, the shape and size of the outer edge, in order to improve the appearance, the outer surface of the guide groove should be closely attached to the body.

The steel strip for the sealing strip is roughly divided into two types, that is, the steel strip and the dense steel strip are broken.

Dense steel strip

The entire surface of the dense steel strip is a piece of steel plate, and the width can be set according to actual needs.

Disadvantages: This product is not easy to deform, the elasticity is small, and the deformation is too large, which will cause cracks on the surface of the strip.

The utility model has the advantages that: after the sealing strip is composited, the surface of the sealing strip is relatively smooth, generally used on the inner and outer sides of the window, and can be well adhered to the window glass to play the role of dustproof and waterproof.

Disconnect the steel strip

The sealing strips on the surface of this product are linked in a sheet shape of about 4 mm wide.

The advantages are: good deformability, relatively soft, generally used for door frames, covers and other parts. This kind of steel strip composite is not extruded in EPDM rubber or PVC and will not be damaged by bending deformation.

The disadvantage is that after the rubber strip is formed, there will be traces of the inner steel strip on the surface. This trace can serve as a decoration, but it is not beautiful in every part.

With the development of science and technology and the improvement of living standards, energy-saving doors and windows have become the mainstream of building doors and windows. Energy-saving doors and windows are roughly composed of profiles, hardware, glass and EPDM sealing strips, and several major processing modules. Sealing strips have been used by many doors and windows because of their low cost and some traditional concepts that do not pay attention to the energy-saving standards of doors and windows. It is ignored by the manufacturer, but the sealing strip plays a vital role in the door and window system. The following is a summary of my knowledge of the design of the sealing strip. I hope that you can better understand the sealing strip.
