Belt grinding technology of key technology (3)
4. Belt grinding key technology Belt grinding technology under the domestic situation and development trend analysis, abrasive belt grinding technology in our country and abroad in the gap, that the belt grinding on the key technologies in the following five main areas .
4.1 basic research, abrasive belt grinding
Belt grinding process with the complex characteristics of the mechanism more complex, contain a more scientific basis, although for many years scholars from various countries on the belt grinding mechanism made a deep study, but so far all Belt Grinding of the basic mechanism of material removal although scholars have done more research, but so far, the complete removal of abrasive belt grinding the basic theory of material yet to be established. Because the surface integrity of the sub-surface layer damage, part geometry and the grinding and polishing process output capacity and other parameters affected by many factors, on an enterprise, it is possible the use of polishing processing or control very well, but In the process before it is almost impossible to predict the processing behavior. Therefore, it is necessary to further expand belt grinding mechanism and related processes. Only by grinding on grinding mechanism and the study revealed a variety of grinding process, grinding nature of the phenomenon, to find out the variation in order to determine the best range of grinding to get the best grinding parameters. This is our industry, a long-term basic research in the field of basic tasks.
4.2 Abrasive Belt and process technology to improve and develop products
Belt belt grinding technology is the key and important sign of whether the belt has been manufacturing high quality as a measure of a country's level of abrasive belt grinding technology standards. Three elements constitute the belt as the matrix, abrasive, adhesive, and the resulting impact grinding performance of 10 kinds of elements, combined in recent years as new polymer materials, new technologies and new techniques in the coated abrasives of the widely used China's vast belt manufacturers and related research institutions should be increased in the following five areas of research and development efforts have independent intellectual property rights for access to high quality belt:
new application and development of the matrix
Belt foreign paper-based matrix of paper pulp by adding additives and coated by dipping and that deal, the paper reached the belt requirements; cloth belt in the cotton fiber with the chemical technology the gradual development of polyester fibers and nylon fibers were replaced, in particular polyester fiber fracture due to its high strength, heat resistance and good water resistance, excellent wear resistance has become a heavy-duty belt fine matrix, foreign countries emerging polyester Ultra-enhanced film-based diamond belt, diamond or CBN electroplated metal base belt, copper and fiber-based products such as diamond abrasive belt, in the processing of non-metallic materials (ceramics and silicon crystals, etc.) has shown the excellent grinding performance. As China-made paper strength, uniformity, water resistance and so fail to belt production requirements, we conduct further research in this area is significant.
Application and Development of Synthetic Slurry
With the polymer industry, the use of synthetic pulp, such as acrylic emulsions and water-soluble phenolic resin slurry, SBR latex liquid slurry with water-soluble phenolic resin, PVA solution and the polyvinyl acetate emulsion slurry materials, antistatic paste, etc. are better applied to the foreign production of synthetic sizing belt which, despite some of our applications, but technology gap with foreign countries is not small compared to.
binder application and development
Polymer binder application and development to promote the development and progress of abrasive belt grinding, especially strong in the dry grinding, wet grinding conditions used in the performance of the binder with the belt is closely related to domestic sand with a short service life of a factor is the large binder problem, it is necessary to use the adhesive on the belt, such as water-soluble phenolic resin, water-soluble resin, water-soluble alcohol-formaldehyde resin, water-soluble white latex, oil-soluble alcohol acid varnish and epoxy resin, etc. in the water resistance and oil resistance, heat resistance, modification of research and testing, thoroughly to improve the quality of our belt.
