How to make the hot melt adhesive coater achieve better performance?

When using the hot melt adhesive coater, we follow the Cao in the manual, but we often can't achieve good results. What's the reason? You must be very confused. Now Xiaobian tells you what to do if you encounter this situation?

Yitong industry and trade (Shanghai) Co., Ltd. is a company providing new products and new process solutions. We not only provide equipment, but also provide new European technologies and processes to Chinese customers through the carrier of equipment. The main equipment is precision coating, mainly including lithium battery coating, optical film coating, brand tape coating, etc. the industries covered include battery, printing, electronics and precision chemical industries.

The application of hot melt adhesive coater should first fill its mold clamping force, and the dispensing amount should be increased · L in appropriate cases. This is because too little glue dispensing will reduce the degree of adhesion and make it impossible to compound.

We can use the anilox roller with deep mesh hole, or increase the dispensing amount on the surface of the plate according to the working pressure of the rubber roller and the contact pressure between the scraper and the anilox roller. For some plastic film plates, corona treatment can be carried out before sizing to make the surface pilling, so as to improve the working ability of the plate to absorb the adhesive and increase the dispensing amount of the surface of the hot melt adhesive coater.

Secondly, special attention should be paid to the selection of air drying temperature. Grasping the air drying temperature can bring excellent characteristics to the application of hot melt adhesive coater. Too high or too low temperature will endanger the bonding color fastness of composite bags.

When the sizing plate is dry and impetuous, it will carbonize the surface of the adhesive and destroy the bonding ability of the adhesive. If the drying temperature is too low, the adhesive will not dry completely. The viscosity of the adhesive is weak and the composite type is not firm. After a period of time, bubbles are easy to occur in the composite bag and destroy the composite quality of the goods.
