1. When cleaning the PUR hot melt machine, the hot melt adhesive heating disc must be separated from the PUR hot melt adhesive barrel. After the PUR hot melt adhesive barrel is separated from the PUR hot melt machine heating plate, the pressure in the lifting cylinder should be maintained. In this case, cut off all power.

2. After the PUR hot melt adhesive machine is detached from the hot melt adhesive drum, 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 machine heating rubber disc, no hard can be used. Quality tool to prevent scratching the pressure plate Teflon coating.

3. When the polyurethane hot melt machine is unbarreled, the air pressure to be charged should be slowly pressurized from small to large. Under any circumstances, it is not allowed to directly use the high pressure gas to directly take off the barrel to avoid accidents.

4. When cleaning the PUR hot melt machine heating platen, the staff must wear special high temperature resistant protective clothing with high temperature resistant gloves. Do not let the skin contact hot melt glue barrel, molten PUR hot melt adhesive and heating plate. To avoid burns.

5. When the PUR hot melt machine is unbarreled, the best way is to fill the 5 gallon hot melt glue tank with dry nitrogen to avoid direct use of undried compressed air. If compressed air is required, The compressed air needs to be thoroughly dried. Always check the use of desiccant.

6. When the PUR polyurethane hot melt machine heating plate pressure plate is separated from the polyurethane hot melt glue barrel, before cleaning the PUR hot melt glue, the special mechanism on the PUR hot melt machine pressure plate must be used to close the pressure plate and the pump body. The passage between them prevents solidification.

7. For the special structure of PUR hot melt machine pressure plate cleaning, because the special structure PUR hot melt machine heating plate can not completely clean the residual PUR hot melt adhesive in a short time, it must be used to dry the residual PUR hot melt. Nitrogen protection, and the time to clean the residual glue should not exceed 10 minutes. Do not use any hard tools to clean the PUR hot melt machine heating plate.
