The recent hot “balloon event” must be seen by everyone. This balloon was made by “Zhuzhou Rubber Institute”. The balloon they made can reach 48000 meters and fly for thousands of miles. At present, it remains at the forefront of the world! Next, let me share some knowledge about “balloons” for you!
Balloons are made of rubber. Rubber is a highly elastic polymer material with reversible deformation, which is elastic at room temperature, can produce large deformation under a small external force, and can recover to its original state after removing the external force. The early rubber is the rubber latex from rubber trees, rubber grass and other plants, which is made of elastic, insulating, waterproof and airproof materials after processing. High elastic polymer compounds are divided into natural rubber and synthetic rubber. Natural rubber is extracted from rubber tree, rubber grass and other plants and processed; Synthetic rubber is obtained by polymerization of various monomers.
Rubber is widely used in aviation, ships, automobiles, daily life and other aspects. Commonly used rubbers include natural rubber, neoprene, ethylene-propylene rubber
Natural rubber has great elasticity, high constant elongation strength, excellent tear resistance and electrical insulation, and good wear resistance and drought resistance. It is suitable for manufacturing torsional vibration eliminator, engine shock absorber, machine support, rubber metal suspension components and molded products; Neoprene rubber has the advantages of excellent oxygen resistance, ozone resistance, non-flammability, self-extinguishing after fire, oil resistance, solvent resistance, acid and alkali resistance, aging resistance and good air tightness. It is mainly used for manufacturing cable sheaths, various protective sleeves and protective covers that require high ozone resistance and aging resistance; Oil and chemical resistant rubber hose, tape and chemical lining; Fire-resistant rubber products for underground mining, as well as various molded products, sealing rings, gaskets, adhesives, etc. Ethylene-propylene rubber has excellent ozone resistance, ultraviolet resistance, weather resistance and aging resistance. It is mainly used for lining of chemical equipment, covering of wires and cables, steam hose, heat-resistant transport belt, rubber products for automobiles and other industrial products.
Songjiang Electromechanical Group has five production-oriented factories. The current rubber products involve natural rubber and synthetic rubber, which are used in military industry, industry, daily life and other fields. The company mainly produces rubber joints, rubber shock absorbers, rubber non-standard parts, shock absorbers of steel, copper, stainless steel and other materials, valves, metal hoses, metal joints and other rubber products. Songjiang Electromechanical Group is a combination of research and development, production, sales, technical support and after-sales service. With advanced equipment and high-tech, it is constantly committed to the rubber products industry. The rubber anti-explosion, shock absorption and noise reduction soft joint produced by the company has three pressure levels higher than that of its peers. Over the years, our products have been highly praised and sold everywhere. It is a long-term cooperative supplier of Gree Air Conditioning, China Construction, China Nuclear and other enterprises.
