Xi'an reaction kettle PU kettle has excellent craftsmanship and outstanding performance

Description :

　　The reaction kettle is an indispensable anti-corrosion equipment in the chemical industry. Mechanical collisions, sudden temperature changes, and other factors often cause porcelain detachment, cracks, bubbles, pores, and other damage to the glaze during use. These defects are never allowed in enamel equipment, and once this phenomenon occurs, it must be repaired. The on-site repair agent of Fushilan polymer composite material is a two-component composite material composed of polymer, alloy steel powder or wear-resistant ceramic powder as the substrate, and a curing agent. Compared with ordinary resin based repair agents, polymer composite materials rely on their finer polymer structure, which gives the material stronger adhesion and excellent corrosion resistance. Polymers can even penetrate into metals, forming a tighter polymer composite protective layer. Repair process: surface cleaning → rust removal → anhydrous alcohol cleaning → Fushi Blue coating bottom repair agent → Fushi Blue coating surface repair agent → curing → use.

　　Installation and operation specifications for reaction kettle

　　1. The high-pressure reactor should be placed indoors. When equipping multiple high-pressure reactors, they should be placed separately. Each operating room should have an exit directly leading to the outside or passage, and the equipment grounding point should be ensured to have good ventilation.

　　2. When installing the kettle cover, it is necessary to prevent the sealing surfaces between the kettle body and the kettle cover from colliding with each other. Carefully place the kettle lid in a fixed position on the kettle body, and when tightening the main nut, it must be tightened diagonally and symmetrically in multiple steps. Apply even force and do not allow the kettle lid to tilt to one side to achieve a good sealing effect.

　　3. At the joint of the positive and negative nuts, only the positive and negative nuts are allowed to be rotated, and the sealing surfaces of the two circular arcs must not be rotated relative to each other. When all nut pattern connections are assembled, lubricating oil should be applied.

　　4. The needle valve system is sealed with a thread. Simply rotate the valve needle gently and press the cover tightly to achieve a good sealing effect.

　　5. Rotate the rotating body on the kettle by hand to check if it operates flexibly.

　　6. The controller should be placed flat on the operating platform, with a working environment temperature of 10-40 ℃ and a relative humidity of less than 85%. The surrounding medium should not contain conductive dust or corrosive gases.

　　7. Check whether the movable parts and fixed contacts on the panel and back panel are normal, remove the cover, and check whether the connector contacts are loose, whether there is damage or rust caused by poor transportation and storage.

　　8. The controller should be reliably grounded.

　　9. Connect all wires, including power lines, electric furnace lines between the controller and the kettle, motor lines, temperature sensor and speedometer wires.

　　10. Close the "power" air main switch on the panel, and the digital display should show.

　　11. Set various parameters (such as upper limit alarm temperature, working temperature, etc.) on the digital display, then press the "heating" switch to turn on the electric furnace, and the indicator light on the "heating" switch will light up. Adjust the "pressure adjustment" knob to adjust the heating power of the electric furnace.

　　12. Press the "Mixing" switch to power on the mixing motor, and the indicator light on the "Mixing" switch will light up. Slowly turn the "Speed Control" knob to make the motor rotate slowly, observe whether the motor is rotating in the forward direction, and when there is no error, stop the machine, hang the belt, and restart.

　　13. After the operation is completed, it can be cooled naturally, cooled with water, or placed on a bracket for air cooling. After the temperature drops, release the pressurized gas inside the kettle to reduce the pressure to atmospheric pressure (the pressure gauge shows zero). Then, loosen the main nut symmetrically and evenly, remove the main nut, and carefully remove the kettle cover and place it on the bracket.

　　Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food, and are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, polymerization pots, etc; Materials generally include carbon manganese steel, stainless steel, zirconium, nickel based (Hastelloy, Monel, Inconel) alloys, and other composite materials.
