If belt can rubber pulp instead of core glue

Mar 18, 2019

The rubber pulp is a gel having a certain viscosity formed by dissolving the core glue in a solvent. After all the volatilization of the solvent, the composition is the same as that of the core rubber. However, the commonly used glue is prepared by using a core rubber and a solvent (such as toluene, xylene, solvent fuel, etc.) in a ratio of 1:5-1:6. The core rubber is a film which is calendered by a calender. Its molecular arrangement is oriented in order, and it is mechanically anisotropic, so the tensile properties and fatigue resistance along the rolling direction are better. The arrangement of the rubber molecules in the solvent is random and is isotropic. The utility of the glue is that the solvent-dispersible rubber can sufficiently enter the between the cloth through the satisfactory fluidity and permeability of the solvent, so that the rubber can be joined to the fabric better. Because the effect of this core glue is to bond the layers of the conveyor belt together, and at the same time eliminate the difference in stress and deformation between the layers of the conveyor belt caused by different thicknesses, and learn from the local damage energy , because This core rubber is a small batch necessary in the conveyor belt. In order to prolong the life of the application, the overseas manufacturer often considers the thickness of the thick core rubber to be suitable.


It is only considered appropriate to use the glue without the core glue, then the thickness of the glue between the layers of the joint is relatively thin, and its application effect will also be affected.
