摘要:
A method for texturing magnetic recording media substrates using a structured abrasive article including a flexible backing having a major surface and an abrasive coating, the abrasive coating attached to and at least substantially covering the entire total surface area of the major surface, where the abrasive coating includes a plurality of precisely-shaped three-dimensional abrasive composites, and the composites comprise a plurality of abrasive particles dispersed in a binder, which binder provides the means of attachment of the composites to the backing.
摘要:
A coated abrasive article comprised of a backing having a layer of grains adherently bonded thereto by a binding material, wherein the layer of grains comprises abrasive grains and nonabrasive composite grains, and the nonabrasive composite grains comprise inorganic nonabrasive particles bonded together by a binder selected from the group consisting of a metal salt of fatty acid, colloidal silica, and combinations thereof. The abrasive article has an unexpected abrading efficiency, performing equal to, or superior to, a coated abrasive article containing only abrasive grains. The invention also relates to a bonded abrasive article comprising the abrasive grains and nonabrasive composite grains adhered together.
摘要:
An abrasive article having sheet-like structure including a major surface extending within an imaginary plane with a plurality of individual three-dimensional abrasive composites deployed in fixed positions thereto in an array, each of the composites has abrasive particles dispersed in a binder and has a substantially precise shape and a distal end, where another imaginary plane extends parallel to and is spaced from the first imaginary plane and intersects the lowest distal end among the composites, wherein any imaginary line drawn within the latter-mentioned imaginary plane in the direction(s) of intended use intersect at least one cross-section among the abrasive composites in the array. The invention also relates to methods for manufacturing such an abrasive article and its usage to refine a work surface.
摘要:
A nail tool comprising a substrate having a major surface and an abrasive article attached onto the major surface of the substrate, where the abrasive article is provided having a sheet-like structure having a major surface having deployed in fixed position thereon a plurality of abrasive three-dimensional abrasive composites, each of the composites comprising abrasive particles dispersed in a binder and having a precise shape defined by a distinct and discernible boundary that includes specific dimensions, wherein the precise shapes are not all identical. The invention also relates to a method for using such a nail tool to abrade the surface of a fingernail or toenail.

摘要:
Method for texturing a surface of a metallic thin film of a magnetic disk substrate comprising the steps of: (a) frictionally contacting the surface of the metallic thin film with an abrasive article, wherein the abrasive article comprises an abrasive coating including a water-soluble binder and abrasive particles, wherein the abrasive coating is adhesively attached to a flexible foraminous fibrous backing; and (b) abrading the surface of the metallic thin film by moving the metallic thin film and the abrasive article relative to one another with the abrasive coating in contact with an aqueous liquid solution to form scratches in the surface of the metallic thin film, wherein the liquid solution is free of abrasive particles before contact is initiated with the abrasive coating.
摘要:
Abrasive articles made using a coatable, addition polymerizable binder precursor composition are described, as well as methods of making same. The compositions comprise a reactive diluent compound and preferably an addition polymerizable resin, the reactive diluent being an organic compound selected to be especially effective in solubilizing aminoplast resins.
摘要:
Abrasive articles comprising precisely shaped particles are disclosed. The particles are bonded together to form a shaped mass, e.g., a wheel; alternatively, the particles can be bonded to a backing to form a coated abrasive article; or the particles can be bonded into a fibrous, nonwoven substrate to form a non-woven abrasive article.
摘要:
A flexible honeycomb panel containing wire or other abrasive material for abrading a workpiece, including a honeycomb core embedded with a quantity of abrasive material, and a facing sheet. The honeycomb core is formed of undulating strips of resilient thermoplastic material that are thermal compression bonded together to form cell walls defining a plurality of contiguous regularly shaped cells. The abrasive material is contained within the strips. The facing sheet, formed of resilient thermoplastic material, is thermal compression bonded to a face of the core. The bonding is accomplished by simultaneously applying heat and pressure to the joinder of the facing sheet and the core. The opposite face of the core remains uncovered. In use, the uncovered face of the core is brought into rubbing contact with the workpiece. The force imparted by the frictional contact is sufficient to wear down the plastic cell wall material, expose the abrasive material, and cause the material to come into contact with the workpiece with sufficient force to abrade the surface of the workpiece.
