The difference between the solvent-free composite and dry compound

Solvent-free composite with solvent dry type composite technology principle of differences mainly reflected in the film and coating method, fastness, formation mechanism, effect and requirements of each process. Table 1 without solvent and dry type composite technology principle of the difference of project or indicators solvent-free composite dry type composite coating way 1, roller transfer coating; 2, rubber thin, uniform thickness; 3, coating weight is mainly decided by the roller speed, can online stepless adjustment. 1, concave roll coating; 2, rubber thicker, as the concave and convex shape, thickness is not uniform; Coating weight is mainly decided by the concave roller line number, can only replace the concave roll limited adjustment. Film and composite fastness to form 1, early low viscous force; 2, film and composite fastness are basically formed in closed curing process; 3, the film formation reaction for two main components of chemical process. 1, the oven heating, high viscous force; 2, film and composite fastness formed on the plane, and curing process only a supplementary role; 3, the film formation is mainly dry evaporate and the physical process of composite pressure. 1, no dry drying and cooling; 2, one-component adhesive need cooling, a two-component glue generally do not need to cool. 1, the necessary working procedure; 2, usually in the form of high temperature drying, drying temperature and cooling temperature and paragraphs have larger influence on composite. Curing for key process, curing temperature and time of reaction to a two-component adhesive which have reached the quality of compound effect usually for auxiliary process, temperature and time have some impact on the quality of composite
