Silicone strip assembly equipment, four composite sealing strip
s-Shanghai Shenya Sealing Parts Co., Ltd. is the first in China to develop and produce composite sealing strips composed of 4 kinds of rubber materials, which are coated on the surface of foam rubber (bubble tube) A thin protective layer of glue can further increase the service life of the seals. The automotive seals are classified according to the surface treatment state. After additional treatment, the surface of the seals can be divided into flocking seals; surface coating seals; yes The special function classification of the automobile sealing strip of the fabric patch seal Some sealing strips have electronic intelligence functions, such as anti-pinch seals. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be a fixed gap, which leads to tightly closed doors and windows. The door and window sealing strips are used to eliminate these gaps. However, there are many types of door and window sealing strips, and their uses are also different. I have compiled some relevant information about the types of door and window sealing strips for everyone here. Door and window sealing strips can be divided into major categories in use: glass sealing strips, door leaf and door cover sealing strips and wool strips. The glass sealing strip is used to seal the gap between the glass leaf and the frame. The door leaf sealing strip is used to seal the gap between the door panel and the door frame, and the wool strip is mainly used to seal the gap between the frame and the door. It is said that in the installation process of various doors and windows, the sealing strip is indispensable. The sealing strip plays a role of sealing and waterproofing in plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have very high requirements for materials. First, they must have strong stretchability and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure the close contact between the sealing strip and the profile, the cross-sectional structure of the sealing strip must match the profile of the door and window, which is generally suitable for hanging windows and folding doors and windows. Of course, rubber sealing strips can also be used in medical applications. No matter which field this product is used in, the effect of use is very good. It can meet everyone's needs and bring you a lot of help. Rubber The use effect of the sealing strip is very ideal, and the color and specifications can be customized according to the needs of customers. The packaging requirements are also installed according to the needs of the customers, so choosing this product can bring you a lot Convenience. Under normal circumstances, EPDM sealing strips can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application areas continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization (the extruded rubber strip
is After a certain length is cut, put it in a vulcanizing tank, and put the extruded semi-finished rubber strip into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.) Several methods). The top is generally used to install on the sash of the push-type door and window to seal the gap between the frame and the sash. The specifications of the tops can largely affect the watertight performance of doors and windows, as well as the opening and closing of doors and windows. If the size of the top is too large, or the vertical hair is too high, it will be very difficult to assemble, and after the assembly is completed, the resistance of the doors and windows will increase when they move. If the fire size is too small, or the vertical hair is too low, the door and window are prone to bracket phenomenon, which reduces the airtightness of the door and window. There are generally two types of tops that have undergone silicification treatment and those that have not been silicified. Generally, the treatment effect will be better. Quality tops have the following characteristics: there are no obvious defects in appearance, the surface is straight, the bottom plate and vertical hairs are relatively smooth, there is no bending phenomenon, and there are no pits and other problems on the bottom plate, and it meets the size requirements. The characteristics of automobile sealing strips In the -40℃ low temperature resistance test, the sealing strips do not become hard or brittle, and still maintain softness and good adhesion of the strips, showing excellent cold resistance. The automotive sealing strips are mainly composed of It is made of ethylene propylene diene monomer (EPDM) rubber with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). Contains unique metal clamps and tongue buckles, which are durable and easy to install. Among the raw materials for sealing strips, EPDM, the main raw material used in the past, is also constantly updated and developed. The new EPDM with excellent physical properties and good processing properties can control the long-chain branching in the molecule and make it The vulcanization performance is better, and the extrusion speed and the output of the product can be improved. These materials have the excellent engineering properties of elastomers and the excellent characteristics of plastics, which are convenient for processing and can be recycled and reused. These materials are gradually replacing EPDM. Products. Doors and windows are the barriers to the quiet living environment. Doors and windows are also important and interesting bridges between people's internal world and the external world. The sealing performance of doors and windows is constantly enriched, and the opening is more and more catering to the needs of life. This significant change Implied the improvement of quality of life
