Some customers reported that the glue valve is not easy to use, and there will be glue leakage after a period of time. After understanding, the reason is that the on-site users do not have the habit of cleaning the glue valve after production every day, and sometimes they do not clean the glue valve for two or three days. In fact, cleaning the glue valve is very simple. Without removing the glue valve, water or alcohol can be used to clean the glue runner. When not in use, the needle can be moved to the anti-dry box to ensure that the glue in the glue valve will not be cured. Change the product or have been used for a long time, it is necessary to clean the rubber valve.
From the point of view of use, the premise of the normal work of the dispensing system is that the internal glue road must be clean. Contamination of the dispensing system is inevitable before the operation of the new equipment, or when the glue is replaced after the dispensing of one equipment.
Glue with different characteristics causes different wear degrees of components. When liquid with large particles enters the glue road, it will produce wear or fatigue wear on the inner wall of parts in the glue road. In the dispensing system, liquid curing and oxidation will lead to surface erosion and destruction of components. And solid particles blocking the hole of the rubber valve will cause the spool blocking and clamping, resulting in the firing pin is not fully in place, will affect the stability of the rubber valve, so that the rubber valve can not work normally. In addition, the liquid with strong fluidity and large amount of glue will also cause erosion wear on the surface of the component.
These are the impact of rubber road not cleaning on the rubber valve. If the rubber valve is not cleaned, it will not only affect the service life of the rubber valve, but also affect the stability of the work of the rubber valve. So I suggest that when the rubber valve is used on the same day, it can be cleaned with a tube of alcohol. If it is not used for a week or a long time, the rubber valve should be removed and cleaned.
