1. When cleaning the PUR polyurethane hot-melt machine, the hot-melt adhesive heating plate must be detached from the PUR hot-melt adhesive barrel. After the PUR polyurethane hot-melt adhesive barrel and the PUR hot-sol machine heating plate are detached, they should be kept in the lifting cylinder Under pressure, cut off all power.
2. When the polyurethane hot melt adhesive machine is off the barrel, the air pressure charged should be gradually increased from small to large. Under any circumstances, it is not allowed to directly use a high-pressure gas to directly take off the barrel to avoid accidents.
3. When the heating platen of the PUR polyurethane hot melt adhesive machine is separated from the polyurethane hot melt barrel, before cleaning the remaining glue of the PUR hot sol machine, the special mechanism on the pressure plate of the PUR hot sol machine must be used to close the pressure plate and the pump body. To prevent curing.
4. When cleaning the heating platen of the PUR hot melt adhesive machine, the staff must wear special high temperature resistant protective clothing and wear high temperature resistant gloves, and do not allow the skin to contact the high temperature parts such as the hot melt adhesive barrel, molten PUR hot melt adhesive and heating plate To avoid burns.
5. When the PUR hot melt adhesive machine is off the barrel, the best way is to fill the 5 gallon hot melt adhesive barrel with dry nitrogen to avoid directly using the uncompressed compressed air. If compressed air is needed, The compressed air needs to be thoroughly dried. And often check the use of desiccant.
6. After the PUR polyurethane hot melt adhesive machine is separated from the hot melt adhesive barrel, the PUR hot melt adhesive remaining on the hot melt adhesive pressure plate must be thoroughly cleaned immediately. When cleaning the PUR hot melt adhesive heating plate, you can not use any Hard tool to prevent scratching the pressure plate Teflon coating. [next]
7. When cleaning the pressure plate of the PUR hot melt adhesive machine with special structure, because the heating plate of the PUR hot melt adhesive machine with special structure cannot completely clean the residual PUR polyurethane hot melt adhesive in a short time, you must clean the residual PUR polyurethane hot melt Use dry nitrogen protection, and the time for cleaning the residual glue should not exceed 10 minutes, and no hard tools should be used to clean the heating plate of the PUR hot melt machine.
8. After cleaning the pressure plate of the PUR hot melt adhesive machine, immediately press the pressure plate into a new PUR hot melt adhesive barrel to avoid exposing the pressure plate to the air for a long time. When pressing the heating plate into the rubber barrel, the air pressure of the lifting cylinder should be from small to large. High-pressure gas should not be used directly to prevent accidents and pay attention to the safety of operators.
9. When pressing the pressure plate of the PUR hot melt glue machine into the rubber barrel, a small amount of silicone oil can be applied to the sealing ring of the pressure plate for lubrication, so as to produce lubrication between the pressure plate and the rubber barrel and protect the use of the sealing ring.
10. When the heating pressure plate of the PUR hot melt adhesive machine is pressed into the new polyurethane rubber barrel, the overflow valve should be opened to completely discharge the residual air in the rubber barrel, and the PUR hot melt adhesive with air bubbles should be removed to avoid The polyurethane hot melt adhesive with air flows into the pump body and the throat of the hot melt adhesive machine.
11. After the pressure plate of the PUR hot melt adhesive machine is placed in the polyurethane hot melt adhesive barrel and the air is removed, the overflow valve is locked. At this time, the air pressure in the stroke cylinder can be appropriately increased to make the work smoother.
12. After replacing the PUR polyurethane hot melt adhesive, you must wait for the PUR hot melt adhesive machine to heat for at least 20 minutes before starting the gear pump and motor. If you start the gear pump and motor immediately, it will cause damage to the polyurethane gear pump and reduce PUR hot melt adhesive. The life of the machine.
