Vitrified Industrial Tiles

Wall Tiles
The process of manufacturing fully-vitrified tiles starts with formulation and formation of the ceramic bodies, made from a blend of kaolin clays, feldspar, silica, and coloring oxides and a contraction control agent.  To produce unfired ceramic bodies with very low moisture content (less than 6.5%), these raw materials are expertly blended, particle size graded, and dried then precision dust-pressed.  Kiln-firing them within a very narrow temperature range (1,135°C to 1,200°C), which varies by Ceramic Tiles Manufacturer, produces fully-vitrified tiles.

To achieve different degrees of slip resistance, specially designed molds are used to integrally form a variety of surface textures and patterns protruding from the faces of fully-Vitrified Tiles.  Because these textures are dust-pressed into the tile faces before they are fired, the resulting profiled surface is dense and durable.  The slip-resistant pattern covers the entire surface of each tile uniformly.

North American food and beverage processors are likely familiar with the slip resistance properties of red shale vertical fiber brick, abrasive tile, and double-abrasive tile. To impart a rough texture for slip resistance, the faces of vertical fiber brick are wire-cut.  This process tears the brick faces, creating potential bacteria har borages on the surface.  Single- and double-abrasive tiles depend upon embedded grit depressed into their surfaces for slip resistance.  The grit is scattered over and pressed into the faces of the tiles as they are extruded.  This process tends to produce a non-uniform surface that is susceptible to erosion under normal wear and tear. Over time, the grit becomes dislodged, leaving a smooth floor surface with small sunken pock-marks.

The following table correlates surface profiles available on fully-Vitrified Tiles, identified by R-values, with surface profiles available from these familiar red shale brick and tile products, as manufactured.  Under similar operating conditions, the slip-resistant surface textures of fully-vitrified tiles could reasonably be expected to last significantly longer than those of red shale acid brick and tile.  In any environment, a clean, dry floor is safer than a dirty wet floor.

Fully-vitrified industrial tiles are available in a variety of shapes and colors.  Three-quarter inch thick (18 mm) tiles featuring integrally formed spacers come in rectangular and hexagonal shapes as shown.  While some architects might choose hexagonal tiles for aesthetic reasons, their shape is also functional.  Hexagonal tiles more readily conform to the variable slopes of drainage basin floors.

Integrally molded spacer lugs on the sides of these fully-Vitrified Tiles create narrow, 2 mm wide joints when butted together.

As the level of a ceramic’s vitrification increases, so does abrasion and chemical resistance.  Fully-vitrified industrial tiles exhibit superior performance when subjected to wear and tear, as well as aggressive sanitizing chemicals.  Fully supported with a bed joint of high-strength adhesive, fully-vitrified industrial tiles perform extremely well under impact loads.
