Introduction of Rubber


Recommended Posts

The rubber material determines the service range and service life of the rubber soft connection. Different rubber materials correspond to different medium environments, and the use of rubber materials not suitable for pipeline circulation media greatly shortens the use effect of the rubber soft connection, which may also have a great impact on the service life of the whole pipeline. Chongqing Feilong Jiangli has many years' experience in manufacturing rubber auto parts. Pls feel free to contact me if you have any interest in us. [email protected]

      Hello,
      Does anyone know where i can find the thermostat shown in the picture?
      I already have a new one with the correct part number but this rubber is missing and it seems that is fixed on thermostat cannot be removed.
      Thank you

      Chongqing Feilong Jiang Li has an independent rubber and plastic workshop, which mainly produces body rubber products, such as bushings, sealing rings and so on. In order to better realize the process and satisfy the design concept, and to ensure the bushing in normal working state more effectively in the process of vehicle assembly, Chongqing Feilong Jiang Li will choose a suitable reference point as the initial zero angle of rubber bushing, which is regarded as the best working state of bushing. In order to keep the best working condition as long as possible, Feilong Jiangli will choose the most common working condition of the whole vehicle as the initial zero angle of the village set. Generally speaking, it is considered that the normal working condition of a car is no-load or half-load, that is to say, the landing state. The corresponding bushing assembly process at this time is called landing tightening technology, that is, tightening the rubber bushing after the vehicle landing. Feilongjiangli's rubber bushing is processed by ingredient, stamping and injection moulding. Each process has strict quality control procedures. The finished bushing is mainly used on Chang'an CS35 and CS75 models.

      Inspection rules for rubber parts for automobiles
      1.rubber hardness
      Test method of indentation hardness based on GBT531.1-2008 rubber pocket hardness tester
      contents and requirements
      Instruments and equipment: Shahr hardness tester (type A, D)
      Environmental conditions: the laboratory temperature is 23 C + + 2 C, the relative humidity is 60%~70231
      Test method: the specimen thickness is at least 6mm. If the thickness of the sample is less than 6 mm, it can be stacked with no more than 3 layers of smooth, parallel samples with each layer thickness not less than 2 mm. The specimen must have enough area to make the needle and specimen contact position at least 12mm from the edge.
      Place the specimen on a solid plane, hold the hardness tester, press the pin at least mm from the edge of the specimen, press the pin smoothly on the specimen, and read it within 3 seconds after the full contact of the pin with the specimen.
      Results: the hardness values were measured 5 times at different locations of 6mm, and the median was taken.
      Feilong Jiangli will update the more inspection rules for automobile rubber parts

      Rubber shock absorber for automobiles
      With the development of social economy, the automobile industry at home and abroad is facing a period of rapid change, which is characterized by further improving the service life of the automobile under the premise of ensuring driving safety, riding comfort, high speed and luxury. Damping products are used to control the vibration and noise of automobiles and to improve their handling stability. They are generally placed in the engine frame, rod holder, suspension shaft lining, center bearing bracket, bump limiter and torsional vibration absorber to improve the safety and comfort of automobiles. Damping products can be divided into four categories: bracket type, shaft lining type, buffer type and damping type. The main requirements of damping, heat resistance and fatigue resistance are good. Automobile shock absorber rubber products include engine bearings, suspension components, rubber springs, rubber air springs and impact rubber protective parts. In recent years, in order to improve the safety, comfort and maneuverability of automobiles, the variety and quantity of shock absorber rubber products for automobiles are increasing as the number of shock absorber rubber products on a car has reached 50-60 pieces.

      5 rubber materials for shock absorption purposes
      NR.SBR.BR is a common citrus material: NBR for oil-resistant vulcanizates; CR for weather-resistant vulcanizates: IR for high damping vulcanizates; EPR for heat-resistant vulcanizates. NR has excellent elasticity, good resistance to fatigue and aromatics, low tart and creep, good cold resistance, electrical insulation and workability. Therefore, NR is widely used as shock absorber in order to meet the requirements of low temperature or weather resistance, and can be modified with BR or CR. The shock absorber made of NR, BR and metal salts containing organic acid containing one OH group with more than 4 carbon atoms has good durability. The compression permanent deformation at 70Cx22h and 40Cx148h is 17.0% and 11.7% respectively. EPDM has attracted much attention in recent years due to its excellent weather resistance, ozone aging resistance, electrical insulation, heat resistance and cold resistance. Recently, Mitsui Chemical Co. and Kwannukawa Rubber Co. developed a new type of heat-resistant and shock-absorbing rubber material by using high molecular weight EIM and low molecular weight EHIM, and obtained a Japanese patent. The test results show that the damping property of the rubber is the same as that of NR, but its heat resistance and low temperature softness are better than that of other rubber such as NR. "The rubber material made of EDM for shock absorbers on automotive parts has very good heat resistance. After 190C *5 aging, the material still has very good interlaminar adhesion. Silicone rubber R or halogenated IR can be used when high damping is required; U has excellent wear resistance, flexibility resistance and resistance to hydrocarbon fuels and most organic solvents, as well as high physical properties, good electrical insulation, adhesion and aging resistance. . U has also been widely used in shock absorption and sound insulation, such as Adachi, etc. The rubber sheet with good shock absorption and sound insulation is made by U. The effect is good when it is applied to floor, ceiling and bending plate.
