Before the preparation of the laboratory magnetic reactor, the reactor should be inspected for contamination. The inner wall of the magnetic reactor, the stirring, the cooling coil, the temperature probe sleeve and the joint surface are cleaned with ethanol, and then rinsed with distilled water. After washing, wipe it with cotton or silk cloth and rub the alcohol to prevent cross-contamination of the material. Before use, it is necessary to check whether the valves are unblocked, especially the pressure gauge and the nozzle of the explosion-proof membrane. For the intake duct, special attention should be paid to the presence or absence of clogging. If there is material contamination or blockage, the duct and the intake branch pipe should be removed from the kettle cover and cleaned before installation.
2. The laboratory magnetic reactor is sealed and cleaned. After the body is dried, the sealing test should be carried out first. Put the kettle body into the heating furnace, put the protruding part into the groove, put the kettle body gently, and after steadyening, slowly and smoothly close the kettle body and the kettle lid, pay special attention to protect the sealing surface. Avoid damage to the seal ring of the lid and the body of the kettle. After the cover is closed, check whether the upper and lower interfaces of the reactor are aligned. Gently swirl the lid to confirm that the lid of the kettle has been flattened. After the gasket is added, start the screw.
3, the laboratory magnetic reactor on the screw precautions must be on the screw when the seat is placed, first tightened by hand, and then use a torque wrench to form a cross-shaped symmetrical ground to avoid uneven force. Do not twist the screw in one position at a time, twist the diagonal screw several times, and gradually tighten the force symmetrically.
4. Laboratory magnetic reactor air tightness inspection When checking air tightness, first check whether each valve (solid feed port, kettle lid exhaust valve, intake valve, etc.) is tightened (eat it, don't overdo it) Force)) After checking the controller's stirring switch and speed control heating switch to zero, turn on the control box power supply and its display switch.
