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，热熔压敏胶从高温发泡到冷却都应该具有很高的内聚强度。

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

1.清洗pur热熔胶机时，热熔胶加热板须与pur热熔胶桶分开。pur热熔胶桶与pur热熔胶机热熔胶加热板分离后，在保持提升气缸内压力的同时应切断所有电源。

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.当聚氨酯热熔胶机取下桶体时，气压应由小到大慢慢增大。在任何情况下，都不允许使用高压气体直接取下桶，以免发生事故。

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.当加热板的压盘PUR热熔胶机是分开的聚氨酯热熔胶桶,压盘上的特殊机制的PUR热熔胶机须使用关闭压盘之间的通道和泵体清洗PUR热熔胶的残留胶,以防止PUR热熔胶机固化。

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热熔胶机热压板时，工作人员须穿戴专用的耐高温防护服和耐高温手套。皮肤不应接触热熔胶桶、热熔胶、热板等高温部位，避免皮肤接触。

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热熔胶机取下胶桶时，办法是将5加仑的热熔胶桶装满干氮，避免直接使用非干燥压缩空气。如需充装压缩空气，需将压缩空气干燥。并且经常检查干燥剂的使用情况。

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.
