After the pur hot melt rubber barrel is separated from the heating plate of the pur hot melt machine, the pressure in the cylinder shall be maintained. In case, please cut off the power supply.
2.聚氨酯熱熔膠機取下桶時，氣壓應由小到大緩慢增加。在任何情況下，都不允許直接使用高壓氣體直接取下槍管，以免發生事故。
2. When the polyurethane hot melt adhesive machine removes the barrel, the air pressure shall increase slowly from small to large. In any case, it is not allowed to directly use high-pressure gas to directly remove the barrel to avoid accidents.
3.當加熱板和壓盤的PUR聚氨酯熱熔膠機是分開聚氨酯熱熔膠桶,壓盤上的特殊機制須使用PUR熱熔機的關閉壓盤與泵體在清洗之前剩余的PUR熱熔膠機。防止通道之間固化。
3. When the pur hot melt adhesive machine of the heating plate and the pressure plate is separated from the polyurethane hot melt adhesive barrel, the special mechanism on the pressure plate must use the closing of the pur hot melt machine, and the remaining pur hot melt adhesive machine between the pressure plate and the pump body before cleaning. Prevent curing between channels.
4.當清洗加熱滾筒的PUR熱熔膠機,員工須佩戴特殊的高溫防護服和高溫手套,和不允許皮膚接觸的熱熔塑料筒,熔融PUR熱熔膠,高溫加熱板等部件。，以避免燒傷。
4. When cleaning the pur hot melt adhesive machine of the heating drum, employees must wear special high-temperature protective clothing and high-temperature gloves, as well as hot-melt plastic cylinders that do not allow skin contact, molten pur hot melt adhesive, high-temperature heating plate and other parts., To avoid burns.

5.PUR熱熔膠機卸膠桶時，辦法是將5加侖的熱熔膠桶裝滿干燥的氮氣，避免直接使用未干燥的壓縮空氣。如果需要填充壓縮空氣，壓縮空氣需要干燥。并經常檢查干燥劑的使用情況。
5. When unloading the glue barrel of PUR hot melt adhesive machine, the method is to fill the 5-gallon hot melt adhesive barrel with dry nitrogen and avoid direct use of dry compressed air. If compressed air needs to be filled, the compressed air needs to be dried. And often check the use of desiccant.
6.PUR熱熔膠機與熱熔膠桶分離后，須立即清洗熱熔膠壓板上剩余的PUR熱熔膠。在清洗PUR熱熔膠機的熱熔膠板時，不要使用任何堅硬的工具，以免刮傷特氟龍涂層的壓板。
6. After the pur hot melt adhesive machine is separated from the hot melt adhesive barrel, the remaining pur hot melt adhesive on the hot melt adhesive pressing plate must be cleaned immediately. When cleaning the hot melt adhesive plate of PUR hot melt adhesive machine, do not use any hard tools to avoid scratching the pressure plate of Teflon coating.
7.清洗時壓盤PUR熱熔膠機的特殊結構,因為PUR熱熔膠機的加熱板的特殊結構不能完全清理殘余PUR熱熔膠在很短的時間內,須清理殘余PUR熱熔時干。氮氣保護，殘留膠水的清洗時間不應超過10分鐘。不要使用任何堅硬的工具清潔PUR熱熔機的加熱板。
7. During cleaning, the pressure plate is the special structure of PUR hot melt adhesive machine, because the special structure of the heating plate of PUR hot melt adhesive machine can not completely clean the residual pur hot melt adhesive, and the residual pur hot melt adhesive must be cleaned in a very short time. Under nitrogen protection, the cleaning time of residual glue shall not exceed 10 minutes. Do not use any hard tool to clean the heating plate of PUR hot melt machine.
8.清洗完pur熱熔膠機的壓板后，立即將壓板壓入新的pur熱熔膠桶中，避免讓壓板長時間暴露在空氣中。將加熱板壓入膠筒時，升降缸的氣壓應由小到大，不應直接使用高壓氣體，以免發生事故，并注意操作人員的安全。
8. After cleaning the pressing plate of the pur hot melt adhesive machine, press the pressing plate into the new pur hot melt adhesive barrel immediately to avoid exposing the pressing plate to the air for a long time. When pressing the heating plate into the rubber cylinder, the air pressure of the lifting cylinder should be from small to large. High pressure gas should not be used directly to avoid accidents, and pay attention to the safety of operators.
9.將PUR熱熔膠機壓板壓入膠桶時，在壓板密封圈上適當涂抹少量硅油。
9. When pressing the pressing plate of PUR hot melt adhesive machine into the rubber barrel, apply a small amount of silicone oil on the sealing ring of the pressing plate.
潤滑使壓板與膠筒之間潤滑，以保護密封圈的使用。
Lubrication lubricates between the pressing plate and the rubber cylinder to protect the use of the sealing ring.
10.PUR熱熔膠機的加熱壓板壓入新型聚氨酯膠桶后，應打開溢流閥，將膠桶內的殘余空氣完全排出，和帶氣泡的PUR熱熔膠應清除，以避免帶空氣的聚氨酯熱熔膠流入泵體和熱熔膠機喉部。
10. After the heating pressing plate of PUR hot melt adhesive machine is pressed into the new polyurethane adhesive barrel, the overflow valve shall be opened to completely discharge the residual air in the rubber barrel, and the pur hot melt adhesive with bubbles shall be removed to prevent the polyurethane hot melt adhesive with air from flowing into the pump body and the throat of the hot melt adhesive machine.
11.將PUR熱熔膠機的壓板放入聚氨酯熱熔膠桶中，排出空氣，然后鎖住溢流閥。此時可適當提高行程缸內的氣壓，使工作更加順暢。
11. Put the pressing plate of PUR hot melt adhesive machine into the polyurethane hot melt adhesive barrel, exhaust the air, and then lock the overflow valve. At this time, the air pressure in the stroke cylinder can be appropriately increased to make the work more smooth.
12.更換PUR熱熔膠后，須等待PUR熱熔膠機加熱至少20分鐘后才能啟動齒輪泵和電機。如果齒輪泵和電機立即啟動，會損壞熔煉機的齒輪泵，減少熔煉機的使用。
12. After replacing the pur hot melt adhesive, wait for the pur hot melt adhesive machine to heat for at least 20 minutes before starting the gear pump and motor. If the gear pump and motor are started immediately, the gear pump of the smelter will be damaged and the use of the smelter will be reduced.
