Description
Technical field
The present invention relates to the preparation of flexible pipe, more particularly to flexible pipe of corrosion-resistant and preparation method thereof.
Background technology
The rubber tube in China passes through the development of more than 50 years with industry, and national economy is served and indispensable matches somebody with somebody interplanting
With raising and new diseases especially with China's Mechanization Level, rubber tube band industry is constantly and association area
Interpenetrate, opened up application and the field of rubber tube band, product is widely used in coal, metallurgy, cement, harbour, ore deposit
The fields such as mountain, oil, automobile, weaving, light industry, engineering machinery, building, ocean, agricultural, Aeronautics and Astronautics.In recent years, rubber tube
Band industry adheres to the Scientific Outlook on Development, and kind, specification, the quality of product have obtained lasting, quick, coordination, the development of health, substantially
The demand of domestic market is met, improves the competitiveness in the international market of product.
At present, China has turned into the production of world's rubber tube band and has consumed big country.Whole nation rubber tube band of certain scale
Manufacturing enterprise 812.Counted according to glue tube belt branch of rubber industry association, the annual production of current national conveyer belt reaches 3.6 hundred million
m2, V band yield reach 2,100,000,000 Am, sebific duct yield ranks world's anteposition up to 6.6 hundred million Bm, product yield.2010, China's rubber
Pipe band manufacturing income scale is up to 223.62 hundred million yuan.At the same time, since Eleventh Five-Year Plan, China's rubber tube is with industry specialty
Research and development are constantly being improved, and not only existing rubber tube band is improved in terms of sizing material, technique, performance and cost, made
It is constantly to meet that user requires and adapts to market needs, and new product and new technology are continually developed, fill the domestic gaps, it is many
For the performance of domestic glue tube belt close to or up international most advanced level, this is that home products further squeezes into the international market creation
Condition.According to prediction net investigation, during " 12 ", Chinese national economy will also keep sustainable development, drive coal, steel,
The industrial expansions such as cement, harbour, mine, oil, automobile, weaving, light industry, machinery, this will give development of the rubber tube with industry
Bring good opportunity, it is contemplated that rubber tube band manufacturing marketing scale is up to 36,000,000,000 yuan within 2015.
Production method have shaping and steam vulcanization (cure) method, product performance be rubber tube series of products, with oil resistant, acid and alkali-resistance,
The conveying of the characteristic such as heat-resisting, pressure-resistant and attraction rubber tube.Most of rubber tubes have nontoxic, environmentally friendly, but some requirements are higher
Oil/Gas Pipe, fire retardant is with the addition of in elastomeric material, human body and air can be produced slightly containing poisonous and harmful substance in fire retardant
Influence.The characteristic of rubber tube also has；Physiological inertia, UV resistant, resistance to ozone, high-low temperature resistant (- 80 to 300 degree), transparency be high,
