In the defense industry and machinery industry, high-strength tape adhesives and high-temperature adhesives are used to bond various metals or alloys. In the wire and cable industry, enameled wire is made from wire-coated lacquer and metal wire. In the insulation industry, electrical laminates, mica products and other composite materials are produced from various antistatic tape adhesive resins and various fillers. As well as the bonding of electric porcelain sleeves, it is very important to study the theory of adhesive tape and the application of adhesives.
Moreover, it has a certain flexibility, and the polymer molecules have a linear or branched linear structure. Therefore, the entire macromolecule or segment can diffuse the appearance of the object to be adhered by thermal motion, and the diffusion results in a mutually soluble whole at the adhesive interface. Therefore, the adhesiveness of the tape is a volume phenomenon, and the mutual solubility or compatibility between the adhesive and the adherend which play a major role in the gluing process.
What are the factors that affect the adhesion of antistatic tape? Generally there are the following factors:
1, selection of specifications
2, the type of test board
3. Test board appearance finish (polished or replaced in time)
4. Clean the solvent and the type of solvent on the test board (the solvent is different when using ethyl acetate or toluene or alcohol)
5, the formula of glue
6, the thickness and uniformity of the glue
7. Tested temperature and humidity
8. The type of the bottom (release) paper film (flat level of the rubber surface)
9, the type of release (isolation) agent
