When the hot-melt adhesive dispenser is removed from the door panel for repair, the foamed hot-melt pressure-sensitive adhesive shall be left on the PP film or foamed panel, and any residual adhesive shall not be transferred to the door panel.

重要的是，熱熔壓敏膠從高溫發(fā)泡到冷卻都應該具有很高的內聚強度。

It is important that hot melt pressure sensitive adhesive should have high cohesive strength from high temperature foaming to cooling.

1.清洗pur熱熔膠機時，熱熔膠加熱板須與pur熱熔膠桶分開。pur熱熔膠桶與pur熱熔膠機熱熔膠加熱板分離后，在保持提升氣缸內壓力的同時應切斷所有電源。

1. When cleaning the pur hot melt adhesive machine, the hot melt adhesive heating plate must be separated from the pur hot melt adhesive barrel. After the pur hot melt adhesive barrel is separated from the hot melt adhesive heating plate of the pur hot melt adhesive machine, all power supplies shall be cut off while maintaining the pressure in the cylinder.

2.當聚氨酯熱熔膠機取下桶體時，氣壓應由小到大慢慢增大。在任何情況下，都不允許使用高壓氣體直接取下桶，以免發(fā)生事故。

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

3.當加熱板的壓盤PUR熱熔膠機是分開的聚氨酯熱熔膠桶,壓盤上的特殊機制的PUR熱熔膠機須使用關閉壓盤之間的通道和泵體清洗PUR熱熔膠的殘留膠,以防止PUR熱熔膠機固化。

3. When the pressure plate pur hot melt adhesive machine of the heating plate is a separate polyurethane hot melt adhesive barrel, the special mechanism pur hot melt adhesive machine on the pressure plate must be used to close the channel between the pressure plates and the pump body to clean the residual adhesive of PUR hot melt adhesive, so as to prevent the curing of PUR hot melt adhesive machine.

4.清洗PUR熱熔膠機熱壓板時，工作人員須穿戴專用的耐高溫防護服和耐高溫手套。皮膚不應接觸熱熔膠桶、熱熔膠、熱板等高溫部位，避免皮膚接觸。

4. When cleaning the hot pressing plate of PUR hot melt adhesive machine, the staff must wear special high-temperature protective clothing and high-temperature gloves. The skin should not contact the hot-melt adhesive barrel, hot-melt adhesive, hot plate and other high-temperature parts to avoid skin contact.

5.pur熱熔膠機取下膠桶時，辦法是將5加侖的熱熔膠桶裝滿干氮，避免直接使用非干燥壓縮空氣。如需充裝壓縮空氣，需將壓縮空氣干燥。并且經(jīng)常檢查干燥劑的使用情況。

5. When the pur hot melt glue machine removes the glue barrel, the method is to fill the 5-gallon hot melt glue barrel with dry nitrogen and avoid using non dry compressed air directly. If it is necessary to fill compressed air, dry the compressed air. And often check the use of desiccant.
