How can plastic cloth be glued to plastic steel windows?
Glue is the intermediate between two kinds of materials. It is a kind of fine chemical, which is mainly made of sticky material, physical form, hardening method and classified material. There is a common instant glue (502 common ethyl cyanoacrylate adhesive is a powerful instant), epoxy resin adhesive, anaerobic glue, UV glue (UV curing), hot melt adhesive, pressure-sensitive adhesive, latex etc..
Glue is a substance that holds two objects together. Glue does not exist independently, it must be painted between two objects to play a bonding role. The chemical constituents of the glue, in the water environment. The polymer glue (vinyl acetate glue is a kind of oil derivatives) is a circular particle, the particle radius is generally between 0.5 ~ 5 m. The adhesion of an object is achieved by the tension between the polymer in the glue. In the glue, water is the carrier of the medium, and the water carries the polymer slowly into the tissue of the object. When the moisture in the glue has disappeared, the polymer in the glue will depend on the tension between them to combine the two objects together. In the use of glue, the amount of excessive coating will make the glue in the polymer bodies crowded together; high polymer can not produce a good tension. Polymers are so crowded that they do not form the strongest attraction of each other.
The water between the polymers does not evaporate easily. This is why the thicker the film, the worse the adhesive effect on the adhesive". The amount of coating is too large, the glue is big, it is the filling action, not the adhesive action. The adhesive between the objects is not the adhesive force of the glue, but the cohesive force of the glue". If it is not water soluble, the principle is much the same, that is, instead of water with other solvents.
