PUR熱熔膠機換膠時應注意什么?
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(nèi)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加大。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 can body is removed by the polyurethane hot melt adhesive machine, the air pressure shall 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.當壓板加熱板的PUR熱熔膠機是分開的聚氨酯熱熔膠桶,壓盤與泵體之間的通道通過特殊機制須關(guān)閉壓盤的PUR熱熔膠機,防止固化前清潔其余PUR熱熔膠膠。
3. When the pur hot melt adhesive machine of the pressing plate heating plate is a separate polyurethane hot melt adhesive barrel, and the channel between the pressure plate and the pump body passes through a special mechanism, the pur hot melt adhesive machine of the pressure plate must be closed to prevent cleaning the remaining pur hot melt adhesive before curing.
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。皮膚不得接觸熱熔膠桶、熱熔膠和熱板，以免燙傷。
4. When cleaning the hot pressing plate of PUR hot melt adhesive machine, the staff must wear special high temperature resistant protective clothing and high temperature resistant gloves. The skin shall not contact the hot melt adhesive barrel, hot melt adhesive and hot plate to avoid scalding.
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，避免直接使用未排盡的壓縮空氣。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 to avoid direct use of unexhausted compressed air. If it is necessary to fill compressed air, dry the compressed air. And often check the use of desiccant.
6.pur熱熔膠機與熱熔膠桶分離后，須立即清理熱熔膠壓板上殘留的pur熱熔膠。清洗pur熱熔膠機的熱熔膠板時，不得使用應使用硬工具，以免刮傷壓板上的特氟龍涂層。
6. After the pur hot melt adhesive machine is separated from the hot melt adhesive barrel, the residual 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, hard tools shall not be used to avoid scratching the Teflon coating on the pressing plate.
7.當清潔PUR熱熔膠機的壓盤與特殊結(jié)構(gòu),因為PUR熱熔膠機加熱板的特殊結(jié)構(gòu)不能完全清理殘余PUR熱熔膠在很短的時間內(nèi),須用干燥氮氣保護清潔殘留PUR熱熔膠時,清洗時間不得超過10分鐘,也沒有難以清潔的工具應使用PUR熱熔膠機的加熱板。
7. When cleaning the pressure plate and special structure of the pur hot melt adhesive machine, because the special structure of the heating plate of the pur hot melt adhesive machine can not completely clean the residual pur hot melt adhesive, the cleaning time shall not exceed 10 minutes, and there are no tools difficult to clean. The heating plate of the pur hot melt adhesive machine shall be used.
8.清洗完P(guān)UR熱熔膠機的壓板后，立即將壓板壓入新的PUR熱熔膠桶內(nèi)，避免壓板長時間暴露在空氣中。當加熱板壓入膠筒時，升降油缸的氣壓應由小到大增加。不要直接使用高壓氣體，防止發(fā)生事故，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 shall increase from small to large. Do not directly use high-pressure gas to prevent accidents and pay attention to the safety of operators.
9.當PUR熱熔膠機的壓盤壓到橡膠桶,少量硅油可以應用于壓盤的密封圈潤滑,從而產(chǎn)生壓盤之間的潤滑和橡膠桶和保護密封圈的使用。
9. When the pressure plate of PUR hot melt adhesive machine is pressed to the rubber barrel, a small amount of silicone oil can be applied to the sealing ring of the pressure plate for lubrication, resulting in the lubrication between the pressure plates and the use of rubber barrel and protective sealing ring.
10.當PUR熱熔膠機的熱壓板壓到新的聚氨酯膠桶,溢流閥應打開,完全放電的殘余空氣桶,和PUR熱熔膠氣泡應刪除以避免空氣流入泵體和喉嚨的熱熔膠機。
10. When the hot pressing plate of PUR hot melt adhesive machine is pressed to the new polyurethane adhesive barrel, the overflow valve shall be opened, the residual air barrel with complete discharge, and pur hot melt adhesive bubbles shall be deleted to avoid air flowing into the hot melt adhesive machine of pump body and throat.
11.PUR熱熔膠機壓板放入聚氨酯熱熔膠桶內(nèi)，排出空氣后，溢流閥鎖定。這時，可以適當增加行程缸內(nèi)的氣壓，使工作更加順利。
11. Put the pressing plate of PUR hot melt adhesive machine into the polyurethane hot melt adhesive barrel, exhaust the air, and 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熱熔膠機加熱少20分鐘后，才能啟動齒輪泵和電機。如果立即啟動齒輪泵和電機，會對齒輪泵造成損壞，降低打膠機的使用壽命。
12. After the pur hot melt adhesive is replaced, the gear pump and motor can not be started until the pur hot melt adhesive machine is heated for at least 20 minutes. If the gear pump and motor are started immediately, the gear pump will be damaged and the service life of the glue applicator will be reduced.
