FAQ and Solution to Water Based Spray Adhesive:
|
FAQ |
Possible Causes |
Solution |
|
Weak or no initial bonding strength |
Slow evaporation on adhesive |
Change the working process |
|
Temperature is so low that initial bonding strength is affected. |
Adjust the temperature in working field. |
|
|
The adhesive layer is so thick that causes slow drying speed. |
Adjust the spraying amount based on the correct operation. |
|
|
The adhesive layer is so thin that causes shortage of gel. |
Adjust the spraying amount based on the correct operation |
|
|
Failure to spray |
Low air pressure |
Adjust the air pressure to normal state, 2.5-8kg. |
|
Spray nozzle is stuck by gel |
Clean out the gel from the nozzle by wet towel or finger. |
|
|
Malfunction of spray gun |
Change or fix the spray gun. |
|
|
Uneven spraying |
Low air pressure |
Adjust the air pressure to normal state, 2.5-8kg. |
|
Malfunction of spray gun |
Change or fix the spray gun. |
|
|
Spray distance is too far. |
Adjust the spray distance and angle. |
|
|
Adhesive viscosity is too high |
Addpurified waterto adjust the viscosity. |
|
|
Too misty when spraying |
Spray distance is too far. |
Adjust the spray distance and angle. |
|
High air pressure. |
Lower the air pressure |
|
|
Too scattered when spraying |
Adjust the sector-like spraying method to straight-line one. |
|
|
No air evaporation equipment |
Install air evaporation equipment to remove the unwanted mist. |
|
|
defect of spray gun |
Use spray gun with bigger nozzle. |
|
|
Debonding with material partly stick together
|
Uneven spay causes pile-up of gel |
Adjust the air pressure and distance of spray gun, and spray evenly. |
|
Uneven spray causes shortage of gel |
Adjust the air pressure and distance of spray gun, and spray evenly. |
|
|
Bond without thoroughly drying (mainly occurs in winter and rainy season). |
Bond the material after the adhesive surface dries. It takes 2~3 min. Use oven in wet weather. |
|
|
Stress is not put on all parts of the material. |
Stress on the material evenly. |
|
|
Bond after the best bonding timing. |
Bond the material within the best bonding time. |
Clearance of Spray Gun
Pour out the adhesive from the spray can after use and use tap water to clean it. Then fill in the can with water and spray it out to clean the absorption tube and the gun inner. Alternatively, you can detach pneumatic tube, fill the absorption tube with water, and press the trigger to let the water flow out until the flowing water is as clean as the tap water.
