Silicone strip technology

Silicone strip technology door and window sealing strip type and use Introduction: When we install doors and windows in life, there will always be a certain gap, which leads to tightly closed doors and windows. The role of door and window sealing strips is 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. It is used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the body. Its better maintenance ensures safe and comfortable driving. However, few car owners pay attention to its maintenance, but in fact its maintenance is very It’s important because once it’s aging and damaged, it will cause rain leaks in the cabin and increase the wind noise of the car. Rain leaks can easily corrode the body. We can keep the car sheltered from wind, rain, dust and heat by maintaining it. , The effect of sound insulation, and when the body is shaken and twisted, it also plays a role in buffering, absorbing shock and retaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must maintain it frequently. The auxiliary seal of the compensation ring is a metal bellows called a bellows mechanical seal. 2. The composition of the mechanical seal: There are mainly the following four types of components, a, the main seal: moving ring and static ring, b, the auxiliary seal: seal Ring, c, compression parts: spring, push ring, d, three. At the same time, put the PVC sealing strip and the silicone rubber sealing strip in the freezer compartment of the refrigerator. After a few hours, the PVC sealing strip will feel very stiff and easy to break. , There is no change in the physical properties of silicone rubber sealing strips. Where can it be used? Wooden windows, aluminum-clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Bronze doors, cast aluminum doors, plastic steel doors and windows, etc., 035W/m2K; 5. Fatigue resistance test: imitating window opening and closing 500,000 times, no obvious change in shape 6. Sound insulation test: only IV68 windows with intermediate rubber strips, reducing noise 43 7. The IV76 window with intermediate and additional adhesive strips can reduce noise by 45 decibels. 8. Outdoor aging resistance test: It has been more than 20 years and the performance remains intact. The series of products are environmentally friendly products and do not contain CFC harmful substances. 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 high requirements for materials. First of all, 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. The wool strip 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 greatly 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 it is assembled, the resistance of doors and windows will increase when they move. If the fire size is too small, or the vertical hair is too low, brackets are prone to occur in doors and windows, which reduces 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 hair 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. Silicone strip technology plays a key role in various electrical cabinets. The main performance of EPDM products: the product is non-toxic, environmentally friendly, resistant to aging and high temperature, stable performance, and can maintain good performance in summer and winter. , Considering the process performance of commonly used rubber materials, sometimes it is necessary to use combined rubber, such as natural rubber (NR) and CR and styrene butadiene rubber (SBR), or polyethylene (PE), EPDM and NR rubber and plastics. To improve ozone resistance. Commonly used weather sealing strips include door frame sealing strips, luggage compartment sealing strips, engine box cover strips, etc. Commonly used general sealing strips include front and rear window sealing strips, corner window sealing strips, inner and outer strips, etc. The unique formula design makes EPDM The rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance properties, good elasticity and resistance to compression deformation, long-term use will not crack or deform, and it can be between -50 degrees and 120 degrees. Maintain its original high sealing performance. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass are in contact with the glass, and it is necessary to check regularly for cracks and breaks.
