Snowflakes are white and sticky. Cause: the humidity of the stickers is too high. Solution: Because pasting paper is made of white latex, and the water content of white latex is high, so after the sticker, the resin coating can be carried out after a long time.
1, Snow White sticky hands
Formation reason: sticker humidity is too high.
Solution: Because pasting paper is made of white latex, and the water content of white latex is high, so after the sticker, the resin coating can be carried out after a long time.
Cause: The operating environment temperature is too low
Solution: Some heating measures can be used to raise the ambient temperature
Formation reason: the humidity of the air is too high.
Solution: The board should not be placed for too long after drying, easy to return to damp, should be used as soon as possible.
Formation reason: improper selection of accelerator, curing agent or its poor quality.
Solution: The general use of 5%, 6% concentration of cobalt water and high quality, small water content of curing agent. The gelling time is generally controlled in 4 ~ 6 minutes, and the amount of curing agent is generally 2.5 ~ 3 in the amount of cobalt water.
2. The resin layer is too brittle
Cause of formation: excessive dosage of accelerators and curing agents
Solution: reduce the amount of accelerator curing agent, the gelling time is generally controlled in 4 ~ 6 minutes, the curing agent amount is generally 2.5 ~ 3 in the amount of cobalt water
3. The resin layer is too soft
Formation reason: accelerant, curing agent dosage is too little
Solution: Increase the amount of accelerator curing agent, the gelling time is generally controlled in 4 ~ 6 minutes, the curing agent amount is generally 2.5 ~ 3 in the amount of cobalt water
4, the surface brightness is poor, fullness is poor
Formation reason: the effect of film type
Solution: There are many kinds of film, which must be selected according to their own requirements.
Formation reason: coating thickness influence
Solution: The fullness of general thick coating is better than thin coating.
Formation reason: the selection of resin viscosity influence.
Solution: The thickness of the film formed by the resin with high viscosity is better.
