Abstract
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.
Claims11
A process for suppressing dusting of dusting materials comprising spraying an aqueous dispersion of polytetrafluoroethylene or modified polytetrafluoroethylene onto the exposed exterior surfaces of said dusting material to fibrillate at least part of said dispersion and coat the exposed exterior surfaces of said dusting material with a web of fibrils of polytetrafluoroethylene or modified polytetrafluoroethylene.
A process for suppressing an existing clould of dust above a dusting material comprising spraying a fog of highly atomised aqueous dispersion of polytetrafluoroethylene or modified polytetrafluoroethylene onto the cloud of dust whereby the cloud of dust is at least partially settled.
