摘要:A process and apparatus is described by means of which the pollution of the surrounding atmosphere by the fumes of isocyanate, liberated during the continuous formation of isocyanate-bad polymer foam bunstock, is minimized. The bunstock, after the foam ri and gelation is completed, is pasd through a zone, installed on the bunstock conveyor, in which the foam is subjected to the action of a fine mist of water sprayed on to the top and sides of the foam bunstock. The application of water in this manner does not affect the properties or appearance of the foam and any excess water coating the surface of the foam evaporates during the remainder of the passage of the bunstock down the conveyor. The above procedure is particularly applicable to the production of foam bunstock which is bad on the highly volatile toluene diisocyanate.艾滋病的预防措施
