DUST SUPPRESSION METHOD AND APPARATUS

摘要

The present invention provides a process for suppressing dusting of dusting materials by spraying an aqueous dispersion of polytetrafluoroethylene (PTFE) or modified polytetrafluoroethylene onto the exposed exterior surfaces of the dusting material to fibrillate at least part of the dispersion and coat the exposed exterior surfaces of the dusting material with a web of fibrils of polytetrafluoroethylene or modified polytetrafluoroethylene. The process is especially advantageous for suppressing dusting of dusting materials contained in a pile, stockpile or open-topped container and dusting materials contained in open-topped transport vehicles.
