We all know that rubber is made by rubber trees by artificial cut bark collected raw rubber as raw material, made of, but how it is the process to become such a soft and tough rubber, it what breed? Today is to show you know the rubber products production process and its main three varieties. There are many different kinds of rubber products, but the production process is basically the same. Basic process is: plasticate, mixing, calendering, extrusion, molding, vulcanization six basic process. Raw material preparation, finished goods, of course, finishing, inspection, packing and so on basic working procedure is necessary. processing process is mainly to solve the contradictory between plastic and elastic properties of these two process. Through various means, made of elastic rubber seals with plastic plastic rubber mixing, add various additives into semi-finished products, and then by sulfide with plastic semi-finished products into high flexibility and good physical and mechanical properties of rubber products. In order to satisfy different use requirements, the use of the different additives and process to create the various USES of rubber seals products. 1, the introduction of natural rubber (NR, natural rubber (NR is made from latex rubber acquisition, is a polymer of isoprene. Has the very good wear resistance, high elasticity, breaking strength and elongation. Easy ageing, the air is heated become sticky, easy expansion and dissolved in mineral oil or gasoline, and alkali resistant, but not resistant to strong acid. Advantages: good elasticity, acid. Weakness: the weather resistance, oil resistance, Resistant to vegetable oil) Use: is a raw material for making tape, rubber hose, rubber shoes and is suitable for the production suspension parts, in the car brake oil, such as ethanol with hydroxy liquid used in the products. 2, hydrogenated nitrile butadiene rubber HNBR introduction: hydrogenated nitrile butadiene rubber HNBR is nitrile butadiene rubber through hydrogenation to remove part of the double chain and, after its temperature resistance, weatherability than normal after hydrogenated nitrile butadiene rubber to improve a lot, oil resistance and nitrile butadiene rubber. General use temperature range for the - 25~150 ℃。 Advantage: more butyronitrile has better abrasion resistance, with excellent corrosion resistance, tensile, tearing and compressive properties, and good under atmospheric conditions such as ozone resistance, generally applicable to the laundry or dishwashing detergent. Disadvantages: does not recommend the use of alcohols, esters and aromatic solution. USES: widely used in air conditioning ZhiLengYe, environmentally friendly refrigerant R134a has a system of seal, the seal of automotive engine system. 3, 3-20 EPDM profile: 3-20 EPDM composed of ethylene and propylene copolymerization, so heat resistance, aging resistance, ozone resistance, stability are all very good, but not in sulphur vulcanization. To solve this problem, in the main chain of the EP import minimal has a double chain of the third component vulcanizing EPDM, generally use temperature for - 50 ~ 150 ℃, the polarity solvent such as alcohol, ketone and other excellent resistance. Advantages: good weathering resistance and ozone resistance, excellent water resistance and resistance to chemical compounds, can be used in alcohol and ketone, and resistance to high temperature steam, has good impermeability to gas. Disadvantage: it is not recommended for food use or exposure to aromatic hydrogen. Usage: used for high temperature steam environment seal, sanitary equipment seals or parts of the brake, The brake) parts in the system and radiator ( Car tank) The seals, etc. Seal products focus on production seals, sealing ring, rubber seal, o-rings, foam tape, filter sealing ring, oil seal and other kinds of rubber seal products, 19 years professional experience in technology, can customize the suitable products according to customer demand for the customer, want to know more rubber products advisory url: / phone:
The increasing consumption demand in key segments such as custom rubber seals, custom rubber seals and custom rubber seals have been driving the sales of and its derivatives worldwide.
Knowing these basics of is every essential. But if you don't know how to choose the proper for your specific need, let Ruichen Sealing Co., Ltd. experts be your guide. Enquire us at ORK Rubber Seal Products.
Time is one of the biggest challenges cited by manufacturing rubber seals.
