On the contrary, some thermosetting adhesives will produce small molecular volatile by-products during the curing process(best alumium oxide for glass blasting). For example, water is released when the static aldehyde resin agglomerates. Therefore, it is required that the abrasive grains be crushed by themselves under the action of grinding stress, exposing new sharp blades to continue the grinding process(white fused aluminum oxide refractory). This property is called self-sharpness.

Long-term practice shows that if volatile turning products are not produced during curing, then only a slight pressure is needed to keep the object in contact(white aluminium oxide 180/220). When using thermosetting adhesives, the curing conditions (including temperature, pressure, and time) are preferably strictly controlled according to the conditions recommended by the adhesive manufacturer(brown fused alumina micro). The low-molecular substance has dialysis behavior in the adherend of the adhesive reservoir.


Such pressure is called contact pressure(brown aluminium oxide grit). Of course, it cannot be considered advantageous to increase the curing temperature under any circumstances. For dry thermosetting adhesives, if the amount of oleic acid reaches 1%, the adhesive strength will be completely lost(aluminum oxide blasting grit). This is because the plasticizer has good miscibility with epoxy resin, etc., and will not dialysis and concentrate to the interface area to form an interface layer.


Schonhorn et al. Treated the surface of general polyethylene with CASING method (activation of crosslinking in a pleasant gas) to convert the low-molecular substances on the surface into ionomeric crosslinked structures to remove the weak interface layer(white aluminum oxide 80 grit), and then treated with epoxy resin adhesive Like ethylene, its sticky core strength is significantly improved, and its effect is about the same as that of chemical treatment(brown alumina abrasive).


The above research, such as epoxy resin or low-oxygen ethylene added appropriate plasticizer, not only will not reduce the strength, but also improve the bonding performance(white fused alumina). According to the concept of adsorption theory, the process of producing a weak interface layer is actually the process of desorption of the adhesive molecules in the interface area by low molecular substances(white corundum price). Based on this analysis, Bikerman et al.


The weak interface layer can only be generated when the following three conditions exist simultaneously(white aluminum oxide). Through dialysis, the low-molecular substance migrates to the interface to form an enrichment zone. A new adsorption balance is created on the surface of the sticky substance(white fused alumina abrasives), and the adsorption layer of the conformal or molecular-preserving substance plays a role in understanding the adsorption of the adhesive molecule.


But Bikerman attributed the phenomenon of interface failure of the bonding system to the role of the weak interface layer(white corundum). In fact, in addition to the role of the weak interface layer, there are many other factors that can cause the interface damage of the adhesive(20 mesh aluminium oxide grit). Proposed that under the premise of the wet state, the failure of the adhesive cannot be purely interface damage, that is, the damage that is detached from the interface.
