How much does it cost to install the roof sealing strip? According to the sealing characteristics, the car sealing strip can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Humidity maintenance function includes the following items in the usual maintenance process. First, the detergent must be cleaned. After the cleaning is not done, a layer of protective agent must be applied to prevent aging and prevent anti-aging. dust. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. In the -40℃ low-temperature resistance test, the sealing tape does not become hard or brittle, and still maintains softness and good adhesion of the rubber strip
, showing excellent cold resistance. Automotive sealing strips are mainly made of EPDM rubber foam with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). It is made of dense compound, and contains unique metal clamps and tongue-shaped buckles, which is durable and easy to install. 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. It is used for thermal insulation and insulation of electrical products, internal pipes of drinking water systems, industrial refrigeration equipment, and gas The internal connection of appliances, the sealing of machinery, lamps and other products, and the performance of sealing strips greatly affect the air-tightness, water-tightness, heat loss and other important performance indicators of doors and windows, and the firmness of doors and windows. my country's automobile door sealing strip is one of the important parts of the automobile, 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. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety.

Ensure personal safety. How much does it cost to install the roof sealing strip. Actually, we cannot do without this product in many places in our lives, because its use effect is very good. Friends who don’t know can join me to take a look at Sanyuan B The characteristics of the C-sealing strip. Third, the ozone resistance of the ozone-resistant product is very good. It can be completely exposed to the air to work, so that the superiority of the product is more prominent. The resistance of the EPDM sealing strip is The effect of ultraviolet radiation is also very good, and it also has excellent physical and mechanical properties, so it is often used to make airplanes, trains, cars, and so on. For car sealing strips, we must pay more attention to maintenance and master the correct maintenance method, otherwise the maintenance effect will not be achieved. Let us understand the importance of car sealing strip maintenance. The characteristics of the product The elasticity and compression resistance of the strip are very good, and it also has good resistance to aging, ozone and chemical effects, etc., making the product very strong and durable during use, and it is also very convenient to install of. The lip length and thickness should be appropriate. Too thick or too long will increase the resistance of the glass to lift. Too thin or too short will cause the glass to not be well guided and sealed, resulting in vibration, noise, and rain leakage; the second is The shape and size of the bottom of the section are designed. There are protrusions on the section of the window steel channel, which is used to assemble the guide groove. Therefore, the bottom of the guide groove section should be designed with a corresponding structure, which is easy to install and can utilize the elasticity of the sealing strip itself. It is attached to the steel guide groove to prevent it from coming out; it is 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.
