浇注型聚氨酯的生产过程(国外英文资料) The plastication process of the sole of polyurethane Name: Xia Yuan [abstract] : the process of plastication of polyurethane sole is introduced in this paper. [authors unit] : the chuzhou institute of vocational and technical college zip: 239,000 【 keywords 】 :?? The process of plastication of the process of plastication [text] : Plastication: by mechanical stress, heat, oxygen or join some methods such as chemical reagent, the high elasticity of rubber by a strong state into the rouran process of plastic state (without synergist, for the purpose of changing rubber elastic and plastic). The essence of the process of plasticide is to break up the molecular chain of the large molecular weight of the rubber, and the chain of large molecules is shorter and shorter. The purpose of the plastic exercise: (1) the plasticity of the plasticity is increased by mixing and dispersing the mixture with the mixture. (2) to improve the liquidity of the adhesive materials, and to extend and extrude the operation, to make the shape and size of the rubber system stable. (3) increase the adhesion of glue and make it easy to form operation. (4) to improve the solubility of the glue in solvent, facilitate the making of glue pulp and reduce the viscosity of the paste, so that it can easily penetrate the fiber hole and increase the adhesion. (5) to make the pattern of the model products sharp and clear. The molding process of PU sole. Technical parameters, equipment for mixer, capacity of 333.7 kg (50, including natural rubber styrene-butadiene rubber 15, 35, butadiene rubber, 40 of reclaimed rubber, sulfur, 2, 5, zinc oxide promoter M1.2, DM1.9 accelerator, stearic acid 3, 70, high wear-resistant carbon black clay 15, light calcium carbonate 5); The speed ratio is 1:1.54. The gel temperature is below 170 degrees Celsius; The plasticiser was 0.51 (wyeth). Operational methods and procedures: (1) to inspect the equipment in accordance with the provisions of the equipment
