The present invention aims to provide an interlayer film for a laminated glass having recesses in the shape of engraved lines on both surfaces to exhibit excellent deaeration properties in production of a laminated glass and suppressing formation of a moire pattern when unwound from a rolled body thereof. The present invention also aims to provide a laminated glass including the interlayer film for a laminated glass, a method for producing an embossing roll suitably used for production of the interlayer film for a laminated glass, and a method for producing the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a large number of recesses on both surfaces, the recesses each having a groove shape with a continuous bottom and being regularly adjacent and parallel to each other, the interlayer film having a glossiness on a surface with the large number of recesses measured in conformity with JIS Z 8741-1997 of higher than 3% or a haze value measured in conformity with JIS K 7105-1981 of 87% or lower.

A suspension medium for improved grit delivery in vapor blast operations sets forth addition of a suspending-agent to a blast solution whereby solids are maintained in suspension absent agitation or mixing for at least 60 hours. The suspending agent increases the viscosity and/or density of the blast solution to increase the buoyancy force and/or acts as a dispersant and/or surfactant to maintain suspension of solids in solution over the extended time period. Different concentrations of suspending-agent may be employed with different grit and solid sized particles, depending on the application of vapor blasting at hand. The suspending-agent is preferably biodegradable.

An amorphous silica particles, gravel, other particles and products provide a safe replacement for crystalline silica sand, grave, or particles in consumer and industrial applications wherein dust may be produced during use or installation. The amorphous silica particles, gravel, other particles or products may comprise components that increase the density, hardness, and other properties from container glass. These components include, but are not limited to, iron oxides, aluminum oxides, and zirconium oxides.

A method for treating and phosphatizing a metal board without using acid includes the following steps: performing a degreasing step to remove grease and dirt from a surface of the metal board with a degreasing agent; performing a blast-peening step by blasting and peening polygon blast-peening granules on the metal board through a centrifugal impeller to remove an oxidized layer; performing a washing step to clean remaining powders from the metal board after the blast-peening step; performing a phosphatizing step to form a protective phosphate coating on the metal board; performing another washing step to wash off remaining phosphatizing agents from the metal board; performing a rustproofing step to apply a rustproofing agent on the metal board; and performing a drying step to dry the metal board.

A method of protecting a gas turbine component for operation in a high temperature environment that includes the gas turbine component including a substrate having a silicon-containing layer, wherein the gas turbine component has a curved surface; forming a flexible mask configured to cover the curved surface of the gas turbine component, the flexible mask including a plurality of slots disposed in a pattern; disposing the flexible mask in direct contact with the curved surface of the gas turbine component; applying a bondcoat onto the flexible mask and the gas turbine component, such that bondcoat fills the plurality of slots and contacts the curved surface; and removing the flexible mask by heat or chemical reaction, such that, after removing the flexible mask, the curved surface of the gas turbine component comprises a patterned bondcoat layer in the pattern defined by the flexible mask.

A surface treatment method includes a step of irradiating a workpiece with a pulsed laser beam through a transparent liquid and a step of causing particles to collide with a heat-affected layer developed on a surface layer portion of the workpiece in the step of irradiating. The particles each has a core made of an elastic body and abrasive grains provided on a surface of the core.
