Physical anti-corrosion of PPH winding tank: during processing, appropriate oily film-forming agent is used in the mesh, so that the anti-corrosion effect of the produced equipment will be much better when it is used. For example, the use of some lead containing pigments and oil together can make the anti-corrosion coating more compact, which will also reduce the penetration of substances to the equipment. Phosphate pigments are basic acid salts that are difficult to dissolve after hydrolysis, which can effectively block the pinholes in the coating. The oxide produced by iron or the flake mica powder and other pigments can reduce the permeability of the anti-corrosion coating when filling, so the PPH winding tank can play a good role in anti-corrosion physically.

Working principle of PPH waste gas purification tower: there are multi-stage packing rings inside. During operation, waste gas flows upward from the bottom. Due to tangential entry into the tower, especially the guiding role of the packing layer, the rising flue gas rotates, resulting in good contact between the packing layer and the pollutants in the waste gas and the liquid, which has a large contact area between the gas and the liquid; The droplets will also rotate through the air flow, and the centrifugal force generated will enhance the gas contact at night. After being thrown to the tower wall, the liquid drops will flow down the wall and reach the next layer of packing through the overflow device. The nozzle will atomize again to contact with gas and liquid. The liquid can be effectively separated after full contact with the gas, and the dust particles in the gas will be removed by adhering the water mist to the filler layer. In addition, dust and fog drops will be thrown onto the tower wall under the action of centrifugal force, and flow to the bottom of the tower to be removed, thus reducing the possibility of dust and fog drops brought by air flow from the tower.

The raw material of PPH mixing tank is PPH granular material, and the raw material of PP storage tank is polypropylene plate. The price of PPH granular material is more expensive than polypropylene plate; The processing of PPH mixing tank requires the use of steel molds. Before processing, natural gas is used for preheating. The startup cost is high. The PP storage tank is directly rolled into a tank with polypropylene plates, which costs little; The PPH mixing tank needs to use electric heating to melt and extrude the particles onto the steel mold, which consumes a lot of power. The PP storage tank only has the power of the welding gun, which consumes less power; The PPH mixing tank needs to be cooled and then demoulded, which are all performed by electric devices, but not the PP storage tank; The PPH mixing tank is welded with a large extrusion electric heating gun, which consumes a lot of power. The PP storage tank is welded with a small manual gun, which consumes less power; Others, such as steel mold replacement, equipment land occupation and equipment maintenance, are not required for PP storage tanks.

Welding technology of PPH storage tank. In terms of automatic welding equipment and welding materials for large storage tanks, the degree of localization is not high enough, especially the automatic welding wire matching the imported high-strength steel plate, which still depends on imports and has high prices. This is a problem that China's PPH storage tank manufacturers must solve in the future; The research and application history of submerged arc automatic transverse welding for flip chip storage tank is not long, and there are still many problems to be solved; There is no doubt that CO2 semi-automatic gas shielded welding technology has obvious advantages over traditional shielded metal arc welding, but there are still many problems to be solved if this method is to be widely popularized and applied outdoors. First, the auxiliary equipment should be portable and flexible, and the wiring should have sufficient length. According to different weldments or parts, corresponding wind proof auxiliary devices shall be developed. It can be predicted that the development trend of welding technology of pph tank manufacturers will have a good application prospect in the welding fields such as petrochemical industry; Gas shielded welding with flux cored wire will be the development direction of large pph tank manufacturers. In the welding of low-temperature storage tank, automatic welding is beneficial to ensure the stability of low-temperature impact performance of heat affected zone.

PPH storage tank vertical storage tank is a plastic storage tank made of PPH granular materials after processing. The barrel of PPH storage tank is made of PPH granules through extrusion and winding process, and the product is formed at one time without welding. PPH storage tank is made of polypropylene plate by welding. From the perspective of corrosion resistance, the corrosion resistance of PPH vertical storage tank is similar to that of PPH vertical storage tank. From the perspective of safety performance, the PPH tank cylinder is integrally formed without welding and leakage, while the PPH tank is welded, which is easy to cause leakage and increase unsafe factors. And there is a big gap between the other properties of the two, such as anti-aging performance. The nozzle installation is the last process, which is equivalent to the reduced version of bottom welding. That is, the imported small automatic extrusion welding unit is used to weld the connecting pipe and flange into shape, and then the hole opener is used to cut the corresponding caliber on the tank body, and then the domestic portable extrusion welding is used. PPH storage tanks are widely used in chemical, pharmaceutical, dye, chemical fiber, metallurgy, textile and other industries to store various corrosive media. The utility model has the advantages of long service life of corrosion resistance, light self weight, safe transportation, convenient maintenance, etc.
