Patent number: 6998067Abstract: 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.Type: GrantFiled: November 10, 2003Date of Patent: February 14, 2006Inventors: Hirofumi Tsutsumi, Teruo Urano, Masatsune Ogura, Tetsuya Shimoda

Patent number: 5480584Abstract: 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.Type: GrantFiled: April 26, 1995Date of Patent: January 2, 1996Assignees: Murakashi Lime Industry Co., Ltd., Nippon Hodo Co., Ltd., Dupont-Mitsu Fluorochemicals Co., Ltd.Inventors: Teruo Urano, Hiroshi Miyaji, Masatsune Ogura, Tetsuya Shimoda, Katuaki Ishikawa
