HM-PSBR Latex Coagulate Into Powder Technology

Mooney SBR powder high (HM-PSBR) is a statement of benzene was 23.5%, Mooney viscosity of 120±5, mean diameter≤1.25mm powdered milk together SBR. HM-PSBR with the corresponding non-use of powder or flake the same SBR. However, as is a powder form, it is particularly suitable for the manufacture of rubber products, injection pressure, the pressure from a variety of molded products, and products. Can be used for rubber products, resin modifier, asphalt modification, adhesives, and tires. The HM-PSBR Results benzene moderate, high Mooney viscosity, the modified asphalt have a balance of high and low temperature performance characteristics, especially for asphalt roads, heavy traffic asphalt, modified asphalt emulsion, fillers, water volume Materials, hydraulic asphalt modifier.This paper studies the HM-PSBR preparation process and its influencing factors. First, small scale experiments discussed by HM-PSBR impact factors key performance indicators. Then in a small trial conducted on the basis of pilot test study, the formation of a high Mooney latex powdered formula and process conditions. Finally, the middle test provides the basis of formulation and process conditions, by 3,000 tons/year pilot-scale industrial scale, optimize the formulation, process conditions and related equipment to adjust the transformation of the industrial production of powder HM-PSBR condensed into powder ratio (≤1.25mm) maintained at 98%, the final product yield of 97%, to 3,000 tons/year PSBR device on an industrial scale production conditions.
