Patent number: 7879144Abstract: The present invention is a fly ash filler or filler blend having a particle size distribution with at least three modes that can be combined with a polymer at higher filler loadings to produce a filled polymer for polymer composites that, in many cases, can produce improved mechanical properties for the polymer composites over polymer composites using conventional fillers. As a result, superior polymer composites (e.g. those used in carpet backing) can be produced at a lower cost than conventional polymer composites. The present invention also includes a method for producing a polymer composite, comprising the steps of combining a polymer with a fly ash filler or a filler blend having a particle size distribution with at least three modes to produce a filled polymer and producing a polymer composite with the resulting filled polymer. The present invention further includes a method of determining what fly ashes can be used as fillers for polymer composites.Type: GrantFiled: July 3, 2007Date of Patent: February 1, 2011Assignee: Boral Material Technologies Inc.Inventors: Raymond T.

Publication number: 20090258777Abstract: A method and system for treating fly ash with a treating fluid by evenly dispersing a treating fluid into a flowing stream of fly ash. By dispersing the treating fluid into the fly ash as the fly ash is flowing, the method takes advantage of natural mixing and particle motion that occurs during flow of the bulk solid. The application of treating fluid is advantageously controlled by an automated controller that has inputs and outputs that allow the controller to adjust flow rate of the treating fluid in correspondence with a measured flow rate of the fly ash.Type: ApplicationFiled: June 19, 2009Publication date: October 15, 2009Applicant: BORAL MATERIAL TECHNOLOGIES INC.Inventors: Marc-Andre Tardif, Russ K.
