Ping township oil seal Small make up to tell you The processing of rubber
Natural rubber is made by latex, latex in the part of the rubber component stay solid natural rubber.General natural rubber of rubber hydrocarbon containing 92% - 92%, instead of rubber hydrocarbon accounted for 5% to 5%.Due to different process, producing area different rubber and adopt different season, the proportion of the ingredients may have differences, but basically within the range.
Protein can promote rubber vulcanization, delay aging.Protein, on the other hand, has the strong water imbibition, can cause rubber damp mildewy, insulation, protein and increased heating shortcoming.
Acetone extract is senior fatty acids and sterols substances, including some role natural protective agent and accelerator, and can help powder compound in the process of mixing dispersion and raw rubber softening effect.
In the ash mainly containing magnesium phosphate and calcium phosphate salts, have a very small amount of copper, manganese, iron and other metal compounds, because the base metal ions can promote the rubber aging, so their content should be controlled.
Moisture in the dry glue not more than 1%, in the process of machining can be volatile, but when moisture content is too much, not only can make the rubber easy mold storage process, but also affects the rubber processing, such as mixed compound easy cluster;Bubbles, calendering, extruding process sulfide in the process of bubble or a cavernous, etc.
