Bortala quartz sand acid pickling deacidification vibrating screen high temperature hydrofluoric acid resistant anti-corrosion material

Position and function of vibrating screen in quartz sand pickling process: deacidification and dehydration

In the screening process, the screen cleaning device located under each layer of the screen constantly impacts the screen through frequency vibration, so that the materials on the upper layer of the screen can be smoothly screened through the screen, and effectively solves the problem of material blocking. Materials with different mesh numbers are discharged at the outlet of each layer after passing through the corresponding mesh number of each layer of the screen, finally achieving the purpose of screening, impurity removal or filtering and grading.

The vibrating screen is widely used in the classification or separation of building materials, coal, metallurgical powder, chemical industry, grain, and other powder and medium and small size materials. Especially suitable for particle size 0.074~5mm , water content lower than 7% Screening of various dry powdery or granular materials with low viscosity.

ZS-1033 It is mainly applied to the inner and outer walls of the dewatering vibrating screen box, the cross beam and the surface of the steel bar fixing the screen mesh to prevent the corrosion of residual hydrofluoric acid and other acids. Due to the large mechanical vibration of the equipment, the substrate treatment effect before coating must be guaranteed, especially the relatively uniform roughness, and then the pre coating is essential. The better coating should be as thin as possible, and the interval between the second coating and the better coating should be as long as possible.

ZS-1033 The hydrofluoric acid resistant anticorrosive coating is modified with phenolic resin grafted with fluorine ion to form a film-forming solution, with barite, flake graphene, etc. as fillers. After curing, the coating has high inertia, and the density of Zhisheng Weihua fluoric acid coating is high, and the temperature resistance can reach 150℃ 。 After the film forming solution in the coating and inorganic filler are mixed and cured, the poly modified phenol fluoride resin is more stable, not easy to lose electrons, and has good swelling resistance. The barite, graphene and other materials specially made by Zhisheng Weihua have good chemical stability and high hardness in the coating. The smaller particle size can also form a dense film in the film forming solution, which can not only withstand the strong acid corrosion of hydrofluoric acid, but also effectively solve the penetration corrosion of fluoride ions.
