PROCESS AND DEVICE FOR THE PRODUCTION OF PLASTICS FROM AT LEAST TWO FREE-FLOWING REACTANTS |
摘要 |
The maintenance of the exact metering ratio during the production of plastics, particularly foams, from free-flowing reactants loaded with pulverulent to fine-grained or fibrous additives can be improved by mixing the additive in compacted form in a preliminary mixer with at least one of the reactants. The pressure in the preliminary mixer is kept constant.
