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.

The thickness requirements for the bottom plate and top plate of PPH storage tank, the previous welding process is to use a portable welding gun to melt the welding rod, and then weld the tank body and bottom plate together. Since the welding rod is an external accessory, it cannot guarantee the consistency of the material with the bottom plate and tank body, which has a certain impact on the quality of equipment. Using a portable welding gun to weld, it cannot achieve the same welding strength, and the weld surface is uneven, There are many hidden dangers for equipment leakage. The bottom plate and can body are welded by mechanical welding process, which can be divided into external welding and internal welding. The external welding of PPH storage tank is a process that uses the imported automatic extrusion welding unit to realize the one-time welding molding of large welds at the stressed parts of the storage tank. The new PPH granular material with the same property as the tank body is hot melted at the large weld seam, and is integrated with the tank bottom and tank body. Internal welding is an automatic long arm extrusion welding process, which is an important step in all processes. Its principle is the same as external welding, but its equipment is different.

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.

HDPE is a part of the plastic recycling market with rapid growth. This is mainly because it is easy to reprocess, has a limited degradation characteristics and is widely used in packaging. The main recycling is to reprocess 25% of recycled materials, such as post consumer recyclables (PCR), with pure HDPE to make bottles not in contact with food. In addition, due to the good insulation performance of HDPE storage tanks, polyethylene is used in many cables, and has good impact resistance even in low environment, In addition, this type of storage tank is more convenient for processing, and can be processed again after use, but it can not be used in industries directly contacting food after secondary processing.

PPH waste gas purification tower is also called PPH waste gas treatment tower. In industrial production, with the chemical processes such as pickling and electroplating, different concentrations of acid and alkali containing gases are generated, causing serious environmental pollution. PPH waste gas treatment tower is an ideal equipment for purifying gas containing acid and alkali. It was successfully developed after digestion, transplantation, test and continuous improvement of imported equipment. Function: Mainly used for environmental protection equipment for acid/alkali waste gas treatment such as sulfuric acid, nitric acid, hydrofluoric acid and hydrochloric acid during operation. The acid mist purification tower has high purification efficiency, compact structure, small floor area, good corrosion resistance, aging resistance, light weight, easy installation, transportation, maintenance and management, etc.

The working principle of PPH waste gas tower is to separate the pollutants in the gas and convert them into harmless substances to purify the gas. It belongs to differential contact countercurrent type. The packing in the tower body is the basic component of gas-liquid two-phase contact. After the gas outside the tower body enters the tower body, the gas enters the packing layer. On the packing layer, there is spray liquid from the top and spray liquid in front, and a layer of liquid film is formed on the packing. When the gas flows through the packing gap, it contacts with the packing liquid film for absorption or comprehensive reaction, The packing layer can provide sufficient surface area without causing excessive resistance to the gas flow. The absorbed or integrated gas is collected by the demister and discharged out of the tower through the air outlet.
