1, choose the adhesive for its use, before use must have enough parking time at room temperature.
2, take into account the adhesive strength and durability of two aspects to choose the appropriate binder.
3, do not use adhesive beyond the storage period and applicable period.
4, single set of rubber if there is stratification, precipitation, before use should be stirred evenly.
5, multi-component glue should be specified in proportion to mix evenly.
6, do not use simple docking, non-docking bonding measures, must take appropriate enhancement measures.
7, as far as possible to use joint, oblique, set, mixed connection.
8,Don't tie the length too long.
9, adhesive laminates do not use the joint, but with oblique connection.
10, add snails and willow, wrap corners around the edges to prevent stripping.
11,The amount of skim solvent should not be too large, preventing moisture in the air from condensing the surface and reducing the adhesion strength.
12, the grease of the sticky surface is cleared clean, should be skim first and then polished in skim.
13,The solvent and fabric used for degreasing and the abrasive used for sandblasting should be replaced in a timely manner so as not to affect the treatment effect.
14,The surface roughness is appropriate and not excessive.
15,After surface treatment, the parking time should not be too long, and should be bonded as soon as possible.
16, before the adhesive surface to be properly preheated(30-40) °C.
17, the amount of glue not too large, the film should be thin not thick, but to ensure that there is no lack of glue.
18,Solvent adhesive coating thickness should be fully dried, but not excessive.
19,The viscosity of adhesives should not be too large. The viscosity can be reduced by heating or dilution.
20,The pressure of the fixture used for assembly is sufficient, and it is not appropriate for it to be too large or too small.
21,Heated and cured adhesive should be gel at room temperature to prevent the flow of glue.
22,Heating cure to heat up the steps, the speed is not too fast, the temperature should be uniform.
23,Pressure can not be put too early. If you want segmented pressure, the pressure should be uniform.
24, cure temperature must not be too high or too low, avoid too cure or not cure.
25,Curing time should be strictly controlled, not long, not short.
26,After curing, cool down slowly. Do not rush to remove the adhesive.
27, as far as possible after curing, eliminate internal stress.
28,The adhesive ambient temperature is not less than 18, the relative humidity is not more than 65 %, the air is clean, and there is no dust to prevent contamination of the sticky surface.
29,Strengthen the inspection of the appearance and performance of the bonded finished product.
