Introduction of Natural rubber


Recommended Posts

Natural rubber (NR) mainly consists of rubber hydrocarbon (polyisoprene), containing a small amount of protein, water, resinic acid, sugar and inorganic salt.
High flexibility, high tensile strength, good tear resistance and electrical insulation, good abrasion resistance and drought resistance, good processing, easy to bond other materials, better than most synthetic rubber in comprehensive performance.
The disadvantages are poor oxygen resistance and ozone resistance, easy to aging and deterioration;
Poor oil and solvent resistance, low corrosion resistance to acid and alkali;
Low heat resistance.
Temperature range of use: about 60 ℃ ~ + 80 ℃.
Making tires, rubber shoes, rubber pipes, tape, insulation and sheaths for wire and cable, and other common products.
It is especially suitable for manufacturing torsional vibration eliminator, engine shock absorber, machine support, rubber - metal suspension element, diaphragm and moulded products.

      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

      Nowadays, more and more driver assistance systems equipped with cameras and sensors can detect objects more effectively than drivers. Moreover, speech recognition technology has already been equipped with vehicle navigation system. Traditional driver assistance system can detect objects (vehicles, pedestrians, etc.) and then inform the driver. However, sometimes drivers will be annoyed by such vague and one-way notification, which will lead to the driver taking the wrong road. In response to such restrictions, Mitsubishi Electric has developed new technologies for intelligent notification and natural navigation functions, which are expected to help make driving safer and more convenient.
      After identifying the direction the driver is facing, the technology uses intelligent notification to alert the driver about objects beyond the driver's sight. In addition, the HMI Natural Navigation System can respond in a natural dialogue when the driver verbally asks questions about the driving route, without pressing a button or saying an activation word.
      Intelligent notification function combines Mitsubishi Motor Maisart image recognition technology and vehicle video camera information to identify potential dangerous objects, such as cars, humans and other moving objects, located outside the driver's line of sight. The object facing the driver is identified by the driver monitoring system (DMS). The system monitors the driver by camera. By comparing the direction of the moving object and the direction of the driver, the blind spot of the driver is estimated. On this basis, the driver is warned by the monitor and the alarm. Tests of Mitsubishi Motor show that the system is particularly effective in detecting objects and attracting driver's attention.
      Natural navigation uses DMS and a series of microphones (multiple microphones that record sound simultaneously) to detect when the driver opens his mouth and to understand the driver's voice cues. It is worth noting that the system can not only recognize voice, but also distinguish the questions that the pilot wants to ask about the navigation system and other irrelevant conversations between the crew. Drivers can talk to the system in a highly natural way to provide and receive information.(Edit by Chongqing Feilong Jiangli)

      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.
