Production process of natural rubber Tags:Rubber Mixers 

  Natural rubber from the latex on the tree to the solid finished product, mainly through the three major steps of coagulation, granulation (tablet), and drying; if it is made into concentrated latex, it is mainly concentrated by centrifugation and other processes.

  The rubber cut from the rubber tree can be divided into natural gel and rural latex. The natural gel is compressed or pelletized, and then dried to produce a product that cools and shapes the belt. The process of producing natural rubber products after the rural latex is solidified is the same, but the rural Concentration of latex without solidified sheep can produce concentrated latex products.

  

  The production process of No. 20 rubber includes raw material pre-treatment, cleaning, crushing, creping, granulating, drying, and pressing. The key steps are crushing, creping and drying.

  Thai No. 20 glue: The primary raw materials come from Cup Lump of thousands of farmers, as well as the green sheets (USS) and tobacco films (RSS) that are simply processed by the farmers. The above raw materials are usually formulated according to a certain formula. Proportions are mixed. During processing, raw materials will be mixed with non-gum materials such as wood chips and sand during tapping, transportation, and storage. Therefore, pre-processing steps such as sorting and washing of raw materials need to be performed before production and processing, and multiple cleaning, Crushing, creping and other processes can remove non-gum materials from raw materials on the one hand, and improve the physical and chemical properties of rubber through processing. After passing through the above multiple processes, the rubber passes through a granulator to be granulated into irregularly shaped pellets with a diameter of less than 0.25 cm, and then enters the drying process, and then the semi-finished product after drying is packed, and the weight and shape are standardized. Of natural rubber. Some factories also use the dry-stirring process to produce No. 20 rubber. This type of production process is relatively simple and the uniformity of the product is poor. The products used for Shanghai International Energy Exchange Center No. 20 rubber futures delivery cannot be made through the dry-stirring process.
