(A), adhesive layer sticky
the reason

1, the temperature is too low, solvent evaporation slow

2, dry time is not enough, too early bonding.

Solution

1, the universal glue cans soaked in 30 ℃ -50 ℃ hot water for 15-25 minutes, and then brushing.

2, to extend the drying time, select the best bonding time.

(B), the layer is rough
the reason
1, the ambient humidity is too large.
2, the use of expired universal glue.

Solution
1, the construction environment ventilation and dry.
2, with the expired universal glue.

(C), rubber layer loose
the reason
1, after the glue, dry time is too short, the plastic contains solvent.
2, a one-time coating is too thick
3, the viscosity is too large, the glue layer contains air
4, gluing environment humidity is too large.
5, was attached to the water content is too high.
6, when the pressure, the pressure is insufficient.

Solution
1, the appropriate extension of dry time.
2, uniform, multiple glue (2-3 times)
3, heating or toluene, ethyl acetate, acetone and other dilution, and then glue.
4, ventilated or replaced places.
5, will be sticky dry or dried and then use.
6, increase the pressure pressure.

(D), layer cracking
the reason
1, the contact surface with bad.
2, the coating layer is insufficient (lack of plastic)
3, when the pressure is too large, the glue is squeezed out.
4, omnipotent glue viscosity is too low, causing lack of glue.

Solution
1, to try in advance;
2, before bonding, lack of glue to make plastic;
3, to reduce the pressure of pressure.
4, to improve the viscosity of glue or multiple glue.

(V), poor adhesion
the reason
1, the table machine is not clean.
2, the surface roughness over.
3, dry time is not enough or too long.
4, the use of expired universal glue.
5, viscosity is too large.
6, re-adhesive when the old plastic is not clean.
7, the surface treatment, the amount of solvent is too large.

Solution
1, for surface cleaning.
2, the surface for reprocessing.
3, control the time to dry.
4, stop using the expired universal glue.
5, heated or diluted with toluene, ethyl acetate, acetone to reduce the viscosity
6, the residue clean clean.
7, reduce the amount of solvent.
