Title:
シート形態の製品、特に研磨製品の製造方法
Document Type and Number:
Japanese Patent JP4139559
Kind Code:
B2
Abstract:
The present invention provides a method of making sheet articles, for example, abrasive articles, retroreflective articles (such as traffic signs), pavement marking articles, or traction or non-skid articles. The method includes passing particles through a thermal sprayer to heat the particles and impinging the heated particles into a polymeric sheet so that the particles are at least partially embedded in the polymeric sheet. Preferably, the polymeric sheet is heated before impingement of the heated particles. One preferred method of softening the sheet is by a thermal sprayer that is used to heat the particles. A preferred thermal sprayer is a flame sprayer having a nozzle for emitting a flame, where the nozzle has a cross-web width and a downweb thickness, the width being substantially greater than the thickness.
