创建于03.24
- Close the feed valve, start the nitrogen cylinder pressure valve to inflate and pressurize, and open the compressed air valve to reach a specific pressure
- Add materials to the polyurethane foaming machine barrel. Do not add the wrong materials and look at the AB materials clearly
- Start the special main valve of the polyurethane foaming machine and the power knob on the left side of the instrument panel. The POWER SUPPLY indicator lights up green, then start the oil pressure system. After stabilization, press the low-pressure circulation button to start the low-pressure circulation
- Start the industrial chiller, set the required temperature, and control the material temperature to the appropriate position
- Set the injection time on the instrument panel and inject materials according to the corresponding requirements on the gun head
- Start the high-pressure circulation, so that the black and white materials in the material tank circulate and exchange heat with the circulating water in the industrial chiller, so that the material temperature of the black and white materials reaches the set temperature requirements
- After the production of the polyurethane foaming machine is completed, close the nitrogen cylinder valve and the compressed air intake valve, then stop the circulation in the foaming machine, reset the power button on the left and pull down the main valve to turn off the power
