Sliding door silicone glass crescent clip door and window sealing strip
type and use Introduction: In our life, when we install doors and windows, there will always be a certain gap, which causes the door and window departments to close 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. 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. B. Sealing strip for continuous vulcanization in salt bath: Salt bath vulcanization adopts a salt bath system containing nitrite, which pollutes the environment and has been gradually eliminated. C. According to the section shape, it can be divided into solid core products (round, square , Flat cross-section shape), hollow products and metal rubber composite products, EPDM rubber sealing strips are much stronger than PVC strips in terms of sealing elasticity and durability, but due to the need for microwave vulcanization line shaping, processing performance High consumption, usually more than 20 times that of PVC processing, the product cannot be reused, it is not environmentally friendly, and it is not an advocated product. Because PVC products contain halogens and heavy metals in stabilizers, they are not conducive to environmental protection. Therefore, developed foreign countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC strips, low temperature elasticity, and the temperature when the tensile capacity reaches 100MPa is -58 , EPDM rubber is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene, international name: EthyienePropyeneDieneMethyiene referred to as EPDM. It is divided into self-adhesive type and card slot type. It is used in different doors and windows. It is more convenient and feasible in operation and installation. What is the performance advantage of coated sealing strip? 1. Compression deformation test: Compression rate of 50% at 70℃ continues to compress 22 hours, deformation rate≤10%2, compression force test, under 25% compression rate, apply a force of 15N/100mm, compression rate≤10N3, temperature range test: from -40℃ to 90℃, the sealing performance is not obvious Change 4. Thermal conductivity K value test: K value ≤ 0 at 0°C. 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. 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. Sliding door silicone glass crescent strips are anti-collision. There will be 'bump! Bump!...' when you close the door and cabinet door for countless times. Will it affect your mood and mood every day? New PU foam sealing strip , Has super resilience, no deformation, tasteless and environmental protection, sound insulation and anti-collision effect is more significant, it is worth having, 5) EPDM rubber material 40°F-248°f (-40°C-120°C), nitrile- Butadiene rubber materials are 40°F-248°f (-40°C-120°C), and silicone rubber materials are 40°F-260°f (-40°C-126. Nowadays, automobiles are also very common and have become With our main transportation tool, the basic function can fill some gaps in the body, so that it can achieve good shock absorption and waterproof effects. Features: 1. EPDM has excellent weather resistance and weather resistance. Long-term resistance to severe cold, heat, dryness and humidity, excellent corrosion resistance to rain and snow, and can completely extend the service life of the rubber strip; 2. Heat aging resistance refers to strong heat-resistant air Aging. All the above characteristics are also the advantages of foam sealing strips. Through understanding, we can find that the reason why this product is popular in the market is because the product has many characteristics and advantages. The temperature in winter is very Low, if the car seal is damaged, it will easily allow air-conditioning to enter the car, and wind noise is also prone to appear. This sound feels like the door is not closed tightly, which will affect the ride. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role.
