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.

The key manufacturing method used in the production of PPH storage tank is one-time forming coiling manufacturing method, so it is simple in structure. The application of PPH storage tank is relatively convenient due to its simple construction. In the actual engineering construction and application, the vertical PPH storage tank usually only considers the static load due to the low application frequency, and the safety performance is slightly increased. For the vertical PPH storage tank with large capacity, the concrete rubber support and the metal rubber support can be considered, but the metal rubber support is too tightly bound, and the plastic has some folding and swelling, It will do harm to the compressive strength of the storage tank, and the appearance is not beautiful. It is proposed to use concrete rubber bearings. Second, for those with small capacity, it is OK to immediately consider plastic rubber bearings.

PPH mixing tank can be divided into two forms: sloping bottom and flat bottom. The corrosion resistant container with full plastic structure is made of modified polypropylene laminate, pure polypropylene or glass fiber reinforced pure polypropylene through secondary processing. Select and configure motors, reducers, mixing paddles, heating devices, etc. according to the actual situation of customers. This product is corrosion resistant, scientific in design, reasonable in structure, excellent in performance, complete in specifications and patterns, safe and reliable in use. It is mainly applicable to the reaction kettle, which is widely used in the material reaction in the production of petroleum, chemical industry, rubber, pesticide, dye, medicine, food and other industries. PPH mixing tank product description: production process: PPH reaction kettle uses PPH spiral extrusion winding unit to process PPH granules into tank body forming process. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. PPH reaction kettle has the characteristics of good integrity, uniform thickness, corrosion resistance, seamless, aging resistance and good leakage resistance. Application field: It is used in chemical industry, metallurgy, rare earth, electronics, dyes, pigments, dyes, environmental protection, pharmaceuticals, power plants, brewing and other industries. Material used: PPH. Product specification: can be customized according to customer requirements.

In the use of PPH storage tank, the process of reaction material mainly depends on the change of storage tank temperature to realize the reaction. When designing PPH storage tank, its pressure and temperature should be standardized. The pressure here refers to the gauge pressure unless otherwise specified. Working pressure refers to the possible high pressure at the top of the container during normal operation. Design pressure: the pressure used to determine the shell thickness at the corresponding design temperature. 1.05 times the high working pressure shall be taken for the internal pressure vessel, and the static pressure of the liquid shall be included. The design pressure of external pressure vessel shall not be less than the possible large internal and external pressure difference under normal operation; Test pressure: refers to the pressure at the top of the vessel under pressure test; The vacuum vessel is designed according to the external pressure. When a safety control device (such as a vacuum relief valve) is installed, the design pressure is taken as the smaller value of 1.25 times the internal and external pressure difference or 0.1MPa, or 0.1MPa if there is no safety control device.
