For sewage treatment Shanghai Songjiang professional manufacturing rubber joints

Soft rubber joints, commonly known as flexible rubber joints, which are widely used in water, electricity, chemicals, boating system, the main performance, high pressure, good elasticity (axial, lateral and angular displacement) noise reduction, light weight, shock move, easy to install, flexible, easy to replace them maintenance, both acid and alkali, oil and so on. The product is in the course of natural variations in weather resistance can be automatically extended. Its construction materials used within dipped nylon tire cord fabric outside of high strength anti-aging polar rubber material. To prevent the natural atrophy and reduce aging product breakdown in the long run, the use of mesh wire multi-body protection. Material rubber joints description: natural rubber (NR) in the rubber hydrocarbon (polyisoprene) mainly containing a small amount of protein, moisture, resin acids, sugars and inorganic salts. Flexibility, high elongation strength, tear resistance and excellent electrical insulation, excellent wear resistance and drought tolerance, good workability, easy to bond to other materials, better than most of the synthetic rubber in terms of overall performance. The disadvantage is resistant to oxygen and ozone resistance is poor, easy to aging deterioration; oil and solvent resistance is bad, the first anti-acid corrosion low; the heat is not high. Operating temperature range: from about -60 ℃ ~ + 80 ℃. Production of tires, rubber shoes, hose, tape, wire and cable insulation and jacketing, and other common products. Particularly suitable for the manufacture of torsional vibration eliminator, engine damper, machine bearings, rubber - metal suspension components, diaphragms, molded products. Styrene-butadiene rubber (SBR) and styrene-butadiene copolymers. Performance close to natural rubber, is the largest general production of synthetic rubber, which is characterized by abrasion resistance, aging and heat resistance than natural rubber, natural rubber is also more uniform texture. Disadvantages are: less elastic, anti-flex, tear resistance is poor; processing performance is poor, especially poor self-adhesive, low green strength. Operating temperature range: from about -50 ℃ ~ + 100 ℃. Mainly used in place of natural rubber to make tires, rubber, hose, shoes, and other common products. Chloroprene rubber (CR) is a chloroprene monomer emulsion made from the polymer. This rubber molecules containing chlorine atoms, as compared with other general-purpose rubber: it has excellent oxidation, ozone resistance, non-flammable, self-extinguishing after the fire, oil, solvent, acid and anti-aging, gas tightness and good; their physical and mechanical properties better than natural rubber, it can be used as general-purpose rubber, it can be used as special rubber. The main drawback is the poor resistance to cold, a larger proportion of high relative cost, electrical insulation is not good, easy to stick roll machining, easy to scorch and easy to stick mold. In addition, raw rubber poor stability and difficult to preserve. Operating temperature range: from about -45 ℃ ~ + 100 ℃. The main requirements for the manufacture of anti-ozone, high resistance to aging and a variety of cable jacket protective cover, protective cover; oil, chemical resistant hoses, plastic and chemical lining; flame underground mining rubber products, as well as a variety of molded products, seals, pads, adhesive or the like. Butyl rubber (IIR) or isobutylene and a small amount of isoprene-butadiene copolymer. The biggest feature is air tightness, ozone resistance, good aging resistance, high heat resistance, long-term working temperature below 130 ℃; resistant to inorganic acids (such as sulfuric acid, nitric acid, etc.) and organic solvents, vibration absorption and damping characteristics good electrical insulation is also very good. The disadvantage is poor flexibility, processing performance is poor, slow curing, poor adhesion and oil resistance. Operating temperature range: from about -40 ℃ ~ + 120 ℃. Mainly used as inner tubes, water births, balloons, wire and cable insulation, chemical equipment lining and shock products, heat-resistant conveyor belt, heat aging tape products. Nitrile rubber (NBR) of butadiene and acrylonitrile copolymer. Characterized by resistance to gasoline and oils of aliphatic hydrocarbons are particularly good performance, after polysulfide rubber, acrylic rubber and fluorine, and superior to other general rubber. Good heat resistance, air tightness, wear resistance and good water resistance etc., strong bond. The disadvantage is the poor cold resistance and ozone resistance, strength and low elasticity, poor acid resistance, good electrical insulation, resistance to polar solvents is poor performance. Operating temperature range: from about -30 ℃ ~ + 100 ℃. Mainly used in the manufacture of various oil products, such as hoses, sealing products.
