Dense Distribution Of Pores On The Surface Of The Cured Adhesive Strip Of The Sealing Adhesive Machine

Touch hardening? How to solve it?
The surface of the adhesive strip of the sealing adhesive coating machine is densely distributed with pores after curing, and the handling method for hand touch hardening
The dense distribution of pores on the cured surface of the adhesive strip after coating can be analyzed from the following aspects:
Analysis 1: The discharge gap between the mixing rod and the mixing cup is too small (plug gap)
Method: When replacing small and large mixing cups and rods, it is necessary to adjust the size of the plug gap in a timely manner
Analysis 2: The discharge amount does not match the size of the mixing cup and rod, resulting in a large discharge amount, a small cup capacity, and uneven discharge
Method: Please adjust the appropriate amount of material to be dispensed in a timely manner
Analysis 3: After replacing the white head at the bottom of the mixing cup, it did not expand the hole, resulting in the nozzle not being able to discharge in a timely manner when the material valve is feeding normally! During this period, the feed pressure value of the material valve will increase slightly
Method: When replacing the white head, please expand the hole in a timely manner
Analysis 4: Long term work without cleaning or cleaning the mixing rod, mixing cup, resulting in a decrease in mixing cup capacity and nozzle diameter
Method: During continuous processing, please clean quantitatively. After a certain period of continuous operation, please open the mixing cup and clean the mixing rod in a timely manner. Soak in the mold cleaner for 5-10 minutes to replace the raw materials or add the raw materials. When adding the raw materials, it is necessary to open the air supply valve to supplement the air in the barrel while stirring the raw materials.
