PPH storage tanks play an important role in people's life, but due to different areas and environments, PPH storage tanks are exposed to different sunlight intensities. The intensity of sunlight will affect the service life of PPH storage tank to some extent, so attention should be paid to protecting PPH storage tank. During the use of PPH tank, if the indoor conditions are much better, but the PPH tank is used outdoors, in order to extend the service life of the tank, z can make a sunshade, and can also brush the appearance of the tank on a layer of light paint a year. In this way, the heat absorption and UV resistance can be reduced, and the anti-aging ability of the PPH tank can be improved. In addition, the strength of PPH storage tank service life has a certain impact on production costs and production benefits. Therefore, factors causing certain damage to PPH storage tank should be avoided during use, especially the sun protection of PPH storage tank.

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.

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.

PPH tank itself uses polypropylene in some new process tanks, so it has better corrosion resistance and other properties when used. In many aspects, its performance is better than that of tanks made of other materials, and its service life is longer under natural conditions. There are many advantages, so before use, please carefully check the PPH storage tank in order to better use it. PPH storage tank shall be used before appearance inspection, and its surface shall be free of crack, shrinkage cavity, slag, folding, heavy leather and other defects. The damage depth of mechanical equipment with corrosion depth and dent depth shall not exceed the allowable value of relative product execution standards. The shell test pressure of PPH storage tank valve shall not be less than 1.5 times of the nominal pressure, and the test time shall not be less than 5 minutes. The shell packaging shall be qualified without leakage. The nominal pressure test shall be conducted, and the valve sealing surface shall be qualified. If you want to soften the PPH storage tank, the temperature is about 100 ℃, so we must control the liquid temperature between minus 40 ℃ and 60 ℃ during storage.

When PPH storage tank is used, the filling rate shall not be greater than 95%, and excessive filling is strictly prohibited. Made of polypropylene, it can contain inorganic acid, malic acid, salt, ammonium, alkali, oil and most gaseous compounds under normal temperature and pressure; The lower cracking temperature and dissolution temperature of PPH storage tank are - 70 ℃ to 108 ℃, and the temperature of the liquid contained is usually between - 40 ℃ and 60 ℃; The filling rate of PPH storage tank shall not be greater than 95% when it is used, and excessive filling is strictly prohibited; When the valves, instruments, pipes, etc. on the equipment are frozen, nitrogen, air or hot water at 70~80 ℃ shall be used for thawing, and open fire heating is strictly prohibited; The PPH storage tank shall be equipped with acid and alkali resistant gaskets when containing acid and alkali liquids, and insoluble rubber gaskets when containing organic solvents; If you are not sure whether you can contain the required substances, you can consult our technical personnel, and if necessary, you can carry out the tank material sample soaking test.
