  • Patent number: 6998067
    Abstract: A method of dusting-preventive treatment in which a powder having dusting property is treated with fibril-forming PTFE (polytetrafluoroethylene) to impart non-dusting property thereto and the non-dusting property of the powder, after having been reduced during transportation, are economically and advantageously recovered or improved through a relatively simple step. The method comprises: a first dusting-preventive treatment step in which fibril-forming polytetrafluoroethylene is added to a powder having dusting property, and a compression/shear force is exerted to the mixture at a temperature in the range of 20 to 200° C. to thereby regulate powder so as to have a flow value of 150 mm to 200 mm; and a second dusting-preventive treatment step in which a compression/shear force is exerted again at a temperature in the range of 50 to 150° C.

  • Patent number: 5788879
    Abstract: In a method for preventing dust of a powdery material by mixing the powdery material with a polytetrafluoroethylene and subjecting the mixture to a compression-shearing action taken at temperatures from about 20.degree. to 200.degree. C. thereby the polytetrafluoroethylene is fibrillated to prevent dusting of the powdery material, the method is characterized by that polytetrafluoroethylene is an aqueous emulsion of a homopolymer of tetrafluoroethylene, the homopolymer has a specific gravity of not larger than 2.20 and an average particle size of 0.10-0.50.mu., and the emulsion contains a hydrocarbon-base anionic surfactant of not less than 1.0 wt % of the polytetrafluoroethylene as the emulsion stabilizer. The emulsion is highly stable and a less possible contaminant of underground water.

  • Patent number: 5480584
    Abstract: Dust-control treatment of dusty powder, which mainly passes through a 100 mesh sieve, such as pigment and fertilizer, is achieved by, firstly blending the dusty powder with fibrillatable polytetrafluoroethylene and a pair of materials capable of initiating an exothermic reaction upon contact, and then subjecting the blended material to compression-shear under the exothermic reaction and raising the temperature of the blended material to 50.degree.-300.degree. C. The polytetrafluoroethylene fibrillates during the compression-shear and the formed fibrils enclose the dusty powder to turn it to a dust-controlled one.
