GFS bolted tank is made of glass fused to steel plate, special sealing material, self-locking screw and other materials. The thickness of enamel steel plate can reach to 20 mm, the most used steel plate thickness is 3~10 mm, steel plate has surface oil, contain rust, contain oxide skin, after shot blasting, sand and other pretreatment process, the steel plate surface will be clean. After 900 ℃ high temperature second enameling in electric furnace, 0.3 mm enamel coating is applied on both sides of steel plate. strong binding force between enamel coating and steel plate. Enamel coating can not only prevent tank corrosion, but also has the function of strong acid and alkali resistance. And has extremely strong wear resistance.
