Zhuhai PPH winding tank manufacturing
The main contents of cleaning the HDPE storage tank are as follows: at the end of each manufacturing, clean the surface of the HDPE container with fingers, and continuously clean the outside of the mechanical equipment with a large amount of water. Damage to the thermal insulation layer is strictly prohibited. According to the processing technology, the solution can be cleaned after a certain period of time. For a long time, more than 72 hours, machines and equipment should be cleaned again before class. It is forbidden to enter acid liquor into the bobbin of this commodity. If the cleaning box requires acid, do not use acid with pH<2. Once the acid enters the casing of this mechanical equipment, hydrogen effect will occur, and the surface will fall like a fish scale on a large scale. The general cleaning cylinder uses 2% of sodium hypochlorite solution and uses tap water to clean the cylinder. The HDPE tank shall be cleaned according to the requirements of Chinese standards. When entering the machine and equipment for cleaning, the water bottle should be padded at the bottom of the sponge pad to prevent special tools from falling in. Wear rubber shoes to prevent damage to the laminated glass. To sort out the actual staff, the records must be sorted out immediately to determine the work experience and the inspection and signature of the project.

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 forming process of PPH storage tank adopts spiral extrusion winding technology with reliable quality. The main processes include tank extrusion winding, external welding, internal seam welding, pipe orifice installation, etc. Can body extrusion winding is the process of using PPH spiral extrusion winding unit to process PPH granules into can body molding. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. The production efficiency of this process is about 5-8 times higher than that of manual process, and the product is flat and beautiful, with good integrity, no joints, good corrosion resistance and leakage resistance. The tank body is thin at the top and thick at the bottom, and the size and shape of the product are not limited. External welding is the process of using the imported automatic extrusion welding unit to make the large weld of the tank with large stress be welded in one time. 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. The process features high mechanization and automation, and stable product quality. The weld specifications can be designed according to the stress characteristics of the product to give full play to the integrity of the weld, reduce flash, and make the joint smooth and beautiful. In addition, the ultraviolet absorber is added to PPH granular material to resist aging and extend the service life.

PPH storage tank mainly includes core processes such as tank body fabrication, bottom, top, manhole, internal and external welding of inlet and outlet flange interface, which will directly affect the integrity, aging resistance, leakage prevention, service life and mechanical strength of the entire PPH storage tank. PPH storage tank body is manufactured by spiral extrusion winding technology. PPH particles are melted on the spiral extrusion winding machine, and then the molten extrusion materials form a can body on the mold. When the temperature is reduced to a certain extent, the tank can be demoulded to ensure the integrity of the tank. However, in the traditional processing form of polypropylene tank, the plate is welded into the tank. Since the very wide plate is 2000 mm, the height of the tank body is generally more than 2000 mm. In actual processing, the tank bodies are welded one by one and then formed manually. Then, for safety reasons, a stiffening ring is added at the connection of the tank.
