Types and purpose of door and window sealing strips Introduction: When we install doors and windows in life, there will always be certain gaps, leading to doors and windows The department is closed tightly. 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. The editor here sorts out some types of door and window sealing strips for everyone. Information. The use of door and window sealing strips can be divided into broad categories: glass sealing strips, door leaf door cover sealing strips and wool strips. The glass sealing strips are used to seal the gap between the glass leaf and the frame. The door leaf sealing strips are used to seal the door panels. In the gap between the door frame and the door frame, the top is mainly used to seal the gap between the frame and the fan. It is said that in the installation process of various doors and windows, the sealing strip is indispensable. The sealing strip is used in plastic steel doors and windows, aluminum alloy doors and windows. And wooden doors and windows play a role in sealing, waterproofing, etc. The sealing strip has high requirements for materials, first of all, it must have strong stretching ability and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure the sealing The sealing strip is in close contact with the profile. The cross-sectional structure of the sealing strip must match the profile of the door and window. It is generally suitable for hanging windows and folding doors and windows. It is made of soft and elastic, non-toxic and odorless after special processing, and can withstand 200 ℃ high temperature, high pressure and repeated cooking, used in electrical products for thermal insulation, internal pipes in drinking water systems, internal connections of industrial refrigeration equipment, gas appliances, sealing of machinery, lamps and other products, and the performance of sealing strips is very good. It affects the airtightness, watertightness, heat loss and other important performance indicators of doors and windows and the firmness of doors and windows. It is suitable for all kinds of doors, windows, etc. 2. Cabinet sealing strips are based on the use of electrical cabinets. Twenty years of experience in the research and development of sealant strips have developed an electrical cabinet seal with its own characteristics-it has the characteristics of good sealing, waterproof, fireproof, insect-proof, windproof, light-proof, anti-collision and long service life. 1 , Three-composite steel frame, not easy to deform and shrink, firm assembly, good airtightness 2. Sealing strip for doors, windows, and curtain walls. The product has good elasticity, resistance to migration, and can effectively block noise, dust, and weather. Wool-like It is used to install on the sash of push-type doors and windows to seal the gap between the frame and the sash. The specifications of the tops can greatly affect the watertight performance of the doors and windows, and also affect the opening and closing of the doors and windows. The specifications of the tops If it is too large, or the vertical hair is too high, it will be very difficult to assemble, and after assembly, the resistance of the door and window will increase when moving. If the fire specification is too small, or the vertical hair is too low Yes, windows and doors are prone to brackets Phenomenon, reducing the airtightness of doors and windows. 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. Four composite sealing strips-Shanghai Shenya Sealing Parts Co., Ltd. took the lead in the domestic development and production of composite sealing strips composed of 4 kinds of rubber materials, and covered with a thin layer of protection on the surface of the foam rubber (bubble tube) Layer glue, thereby further improving the service life of the seals, car sealing strips are classified according to the surface treatment state. After additional treatment, the surface of some sealing strips can be divided into flocking sealing strips; surface coating sealing strips; automotive sealing strips with fabric stickers Special function classification of sealing strips Some sealing strips have electronic intelligence functions, such as anti-pinch sealing strips. my country's automobile door seal
ing strip is one of the important parts of automobiles, and it is one of the important parts that determine the quality of the automobile. What are its more important roles in the automobile, foam sealing strip 1, The basic concept of the mechanical seal: the mechanical seal refers to the prevention of fluid by keeping at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to prevent fluid from sliding. Leaking device.
