How to solve the problem of instant glue turning white and quick-drying glue turning white?

Solution: FirstThe difference between welded white lenses and pc transparent lenses, control the amount of glue usedThe difference between welded white lenses and pc transparent lenses, try not to hit the glue too much, and the glue does not flow out, so that there is no whitening on the bonding surface. It is beautiful and reduces the amount used to reduce costs. You can achieve multiple goals in one fell swoop. Second, use non-albino quick-drying glue, such as CA-60H glue. Third, use a quick-drying glue accelerator to speed up the glue reaction and avoid the generation of white fog.

Solution: Control the amount of glue and wipe it off with solvent as soon as possible if there is any overflow during glue application; use it with quick-drying glue curing glue to speed up the curing of the glue to avoid white fog; increase ventilation in the operation room, and place the bonded product in sealed packaging for 24 hours; Select low-albino quick-drying glue.

How to make quick-drying glue non-whitening; the amount of glue must be controlled well. Too much can easily lead to whitening. Pay attention to ventilation. The air in the working environment is relatively sealed, because the quick-drying adhesive is cured by moisture. During the curing process of the glue, the white mist left behind is easy to form whitening.

White fog marks after glue is dried are common in life and can be roughly divided into three situations: humidity effect: When used in high-humidity environments such as bathrooms and kitchens, moisture will participate in the glue curing reaction and form white salt crystals. This situation is especially obvious when glass glue is applied to mirrors and ceramic tiles are repaired.

The main reasons for the whitening of glue include moisture influence, temperature influence, unclean bonding surface, component oxidation reaction and moisture evaporation residue. The specific analysis is as follows: When moisture affects glue when it comes into contact with moisture, water molecules will react with chemical components in the glue, causing structural changes and whitening.
