Nov 23, 2017

      In the oil , chemical , fertilizer , metallurgy , electric power , pharmaceutical ,pesticide , food , chlor-alkali , environmental protection and other industries in the production process , the media on the equipment , pipelines and accessories corrosion caused by a huge economic loss . According to relevant information , the annual loss caused by corrosion accounts for about 3% -4% of the GNP of the national economy , far exceeding the losses caused by all kinds of natural disasters .

      The use of rotomolding process of the production of anti-corrosion products, lining layer with a uniform thickness , smooth surface , Machinable a wide range of special-shaped pieces , and steel have good adhesion , excellent temperature resistance , superior corrosion resistance And can withstand positive and negative advantages.

      Rotational molding process can be applied to centrifugal pumps , large equipment (towers , tanks , tanks , reactors , all kinds of mixing paddle ) , pipelines andaccessories ,compensators , water jet vacuum pumps , valves and other products. At present , China's use of rotational molding technology to produce products are 100L 5000L reactor , 500mm to5000mm diameter tower section , 1 m 3 to 250m 3 of storage tanks , injectors , mixers ,chlorine distributor , compensation device , a diameter of 25 ~ 800mm, length 2 ~ 6m of pipes and fittings .
