2. When the polyurethane hot melt adhesive machine takes off the barrel, the air pressure should increase slowly from small to large. In any case, it is not allowed to take down the barrel directly with high pressure gas to avoid accidents.

3.當加熱板和壓盤(pán)的PUR聚氨酯熱熔膠機是分開(kāi)聚氨酯熱熔膠桶,壓盤(pán)上的特殊機制須使用PUR熱熔機的關(guān)閉壓盤(pán)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 adhesive machine, and the remaining pur hot melt adhesive machine of the pressure plate and the pump body before cleaning. Prevent solidification 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 pur hot melt adhesive machine of heating roller, employees must wear special high temperature protective clothing and high temperature gloves, hot melt plastic cylinder which is not allowed to contact with skin, PUR hot melt adhesive, high temperature heating plate and other parts., To avoid burns.

5.PUR熱熔膠機卸膠桶時(shí)，辦法是將5加侖的熱熔膠桶裝滿(mǎn)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(jīng)常檢查干燥劑的使用情況。

5. When unloading the glue barrel of PUR hot melt glue machine, the method is to fill the 5-gallon hot melt glue barrel with dry nitrogen to 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(shí)，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 Teflon coated pressing plate.

7.清洗時(shí)壓盤(pán)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(shí)間內,須清理殘余PUR熱熔時(shí)干。氮氣保護，殘留膠水的清洗時(shí)間不應超過(guò)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. Special structure of press plate pur hot melt adhesive machine when cleaning, because the special structure of the heating plate of PUR hot melt adhesive machine can not completely clean up the residual pur hot melt adhesive. In a very short time, it is necessary to clean up the residual pur hot melt adhesive when it is dry. Nitrogen protection, residual glue cleaning time should not exceed 10 minutes. Do not use any hard tools 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(cháng)時(shí)間暴露在空氣中。將加熱板壓入膠筒時(shí)，升降缸的氣壓應由小到大，不應直接使用高壓氣體，以免發(fā)生事故，并注意操作人員的。

8. After cleaning the pressing plate of 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 the heating plate is pressed into the rubber cylinder, the air pressure of the lifting cylinder should be increased from small to large. High pressure gas should not be used directly to avoid accidents, and the safety of operators should be paid attention to.

9.將PUR熱熔膠機壓板壓入膠桶時(shí)，在壓板密封圈上適當涂抹少量硅油。

9. When pressing the press plate of PUR hot melt adhesive machine into the rubber barrel, apply a small amount of silicone oil on the seal ring of the press plate.

潤滑使壓板與膠筒之間潤滑，以保護密封圈的使用。

Lubrication makes the pressure plate and rubber cylinder lubricated to protect the use of 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(kāi)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，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 barrel, and the pur hot melt adhesive with bubbles shall be removed, so as 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(shí)可適當提高行程缸內的氣壓，使工作更加順暢。

11. Put the pressure plate of PUR hot melt adhesive machine into the polyurethane hot melt adhesive barrel, exhaust the air, and then lock the relief 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熱熔膠機加熱少20分鐘后才能啟動(dòng)齒輪泵和電機。如果齒輪泵和電機立即啟動(dòng)，會(huì )損壞熔煉機的齒輪泵，減少熔煉機的使用。

12. After replacing pur hot melt adhesive, it is necessary to wait for PUR hot melt adhesive machine to heat for at least 20 minutes before starting gear pump and motor. If the gear pump and motor are started immediately, the gear pump of smelting machine will be damaged and the use of smelting machine will be reduced.
