In order for various mechanical(garnet blasting media), physical and chemical effects to occur between the adhesive and the adherend to produce adhesion, the adhesive must be applied to the surface of the adherend in a liquid state and completely wet the surface of the adherend. Many polymer solutions can be used as adhesives(brown aluminum oxide 16 grit). It may be more appropriate to use the "surface energy theory" to explain the reasons for the improvement in bonding properties.

The thermoplastic polymer material is heated and melted to obtain fluidity(white aluminum oxide). Increasing the temperature can of course reduce the melt viscosity, but too high temperature will cause thermal degradation of the polymer(white aluminium oxide super fine). The ringing of the adhesive can be carried out by physical methods, such as volatilization of the solvent, condensation of the emulsion, cooling of the melt, or the chemical synthesis of the adhesive into a solid ionomer.

Many polymer melts can be used as cavity adhesives(white corundum). This type of adhesive is called hot melt adhesive. When formulating hot melt adhesives, the contradiction between the strength of the adhesive and the viscosity of the melt must be resolved(aluminum oxide abrasive). Polymer materials must have a sufficiently high molecular weight to have a certain strength and toughness, but the viscosity of the melt also increases rapidly with the increase in molecular weight.

Therefore, in order to improve the fluidity of the hot melt adhesive and the adhesion to the adhered surface, various auxiliary components must be added(black silicon carbide). The duralumin oxidizing electrolyte is made up of sulfuric acid and various organic substances. After infiltrating the adhered surface, the polymer melt can be solidified by cooling(aluminum oxide grit). The curing speed of the solution adhesive depends on the evaporation rate of the solvent, and it is more sensitive to climate.

As mentioned earlier, a hot melt adhesive may contain the following components(silicon carbide abrasive): basic resin, tackifier, extender, filler, antioxidant, because the hot melt adhesive can be solidified as long as the melt is cooled, so it has A series of advantages(synthetic corundum): fast bonding speed, convenient for mechanized operation, no solvent, safe and economical, but hot melt adhesive also has poor heat resistance, it needs to be heated to a higher temperature during bonding.

The curing process of emulsion adhesives is like this(brown fused alumina price); thermoplastic polymer materials can be dissolved in a suitable solvent to become a polymer solution, so fluidity is obtained, and the solvent is volatilized after the polymer solution infiltrates the surface of the adherend. It will produce a certain degree of adhesion(emery abrasive). The most commonly encountered solution adhesive is the rubber solution used to repair the inner tube of the bicycle.

The essence of the curing process of the solution adhesive is that with the evaporation of the solvent, the concentration of the solution continues to increase, and finally reaches a certain strength(green silicon carbide). At present, the adhesives for resin abrasives basically consist of thermosetting resins(low sodium white fused alumina). Thermosetting resin is a polymer with three-dimensional cross-linked structure, it has the advantages of good heat resistance, water resistance, excellent medium, low marriage change and so on.
