The stirrer of the reactor should be opened before the feeding of the resin reactor. When the operation is not noisy or normal, the material should be added to the reactor. The quantity of feeding should not exceed the technological requirements. Before opening the steam valve, the air return valve should be opened first, and then the air inlet valve. The steam valve should be opened slowly to preheat the jacket and step up the pressure. The pressure in the jacket should not exceed the prescribed value.
Resin reactor cooling valve and steam valve can’t be started at the same time, its steam pipeline is not allowed to hammer and collision. When the cooling water valve is opened, the water return valve is opened first and the inlet valve is opened afterwards. The cooling water pressure should not be less than 0.1 MPa, and no more than 0.2 MPa. For the water ring vacuum pump, you’d better start the pump first and then feed water, when stopping the pump, you need to stop the pump first and then stop water, and prevent the water accumulation in the pump.
High-pressure stainless steel reaction kettle of resin reaction kettle should be placed indoors, when equipped with more than one high-pressure kettle, they should be placed separately, each operating room should have direct access to the outdoor or channel outlet to ensure that the equipment site ventilation is good. When installing the lid, the sealing faces between the kettle covers should be prevented from colliding. Carefully place the lid on the kettle body in a fixed position. When tightening the main nut, it must be tightened diagonally and symmetrically several times. Force should be uniform, do not allow the lid to tilt to the side so as to achieve a good sealing effect.
