Adhesive people will certainly encounter difficulties: which materials can be used adhesive?

Adhesives, also known as adhesives and follow-up agents, are firmly connected to two or more surface-treated adhesive materials and have a chemical properties of a certain mechanical strength. For example, epoxy resin, copper monoxide phosphate, white latex, etc.
Types of adhesives
Adhesive bondable materials
1, metal
metal surface oxidation film after surface treatment, easy
to
glue;
2, rubber
the polarity of rubber, the better the glue effect. Among them, butyl neoprene has a large polarity and a strong bonding strength, while natural rubber, silicone rubber and isoprene rubber have a small polarity and a weak adhesion. In addition, rubber surfaces often have release agents or other freeing aids, hindering the glue effect.
3, wood
is a porous material, easy to absorb moisture, causing dimensional changes, may therefore produce stress concentration. In addition, polished materials perform better than rough wood glue.
4, plastic
the polar plastic its glue performance is good.
5, glass
glass surface from a microcosmic point of view is composed of numerous uniform uneven parts. Use a moist adhesive to prevent possible bubble effects at bumps. In addition, glass is si-o-as the main structure, its surface layer is easy to absorb water. Due to the strong polarity of the glass, the polar adhesive is easy to bind with the hydrogen bond on the surface to form a solid bond. The glass is brittle and transparent, and these need to be taken into account when selecting adhesives.
PP material is a non-polar material, the surface can be low, in the PP material surface adhesive process is prone to the substrate and glue between the bonding difference between de-glue and other problems, coating online to tell everyone an effective solution is to PP material surface effective pre-treatment, in addition to basic cleaning, the use of PP treatment agent brush between the substrate and glue to enhance the adhesive relay to solve the de-adhesive problem.
now, should we know something about this?
