摘要:
A marking system includes a composition having at least one color precursor, a moldable substrate having a color developer, and a marking instrument for applying the composition to the moldable substrate to form at least one mark on the moldable substrate. A method of producing a colored three-dimensional molded object includes the steps of manipulating a moldable substrate having a color developer into a molded shape having an outer surface; and applying, on the outer surface of the molded shape, a first composition having at least one color precursor to a first portion of the molded shape.

An apparatus, kit, and methods for forming a bead between bead-forming blocks having internal bead-forming channels are provided. The bead-forming channels of adjacent bead-forming blocks are slidably engaged to manipulate a measured amount of modeling compound between the bead-forming blocks and within an internal space between the opposing channels. In one embodiment, the bead-forming blocks maintain orientation with respect to an axis of travel based on a block guide. Further, the measured amount of modeling compound is determined using an integrated measuring feature coupled to at least one of the pair of bead-forming blocks. The internal volume of an integrated measuring feature corresponds to a threshold amount of modeling compound for manipulating between the pair of blocks and forming a bead while contacting at least a portion of the mated bead-forming channels. In further aspects, a molded bead may be coated with a multicomponent bead-coating mixture. Multi-component bead-coating mixtures and methods of using thereof are provided.
摘要:
A range of processes is described herein for the preparation of a range of gold nanoparticle (Au NP) ceramic glazes with traditional firing methods that represents significant efficiency and ecological advancements over existing methods and allows for the replacement of commercial ceramic colorant methods, while retaining the costly equipment and firing methods already used. The process allows for ceramic surface color while breaking standards for minimal amounts of transition metal colorant used. The nanoparticle-based glazes described here add new colors to the known ceramic surface palette and offers greater consumer safety as an alternative to existing coloring processes that use higher concentrations of toxic metal and an increased risk of metal leaching from the final ceramic vessel into its contents (e.g., soil, beverage, food).

There is provided an apparatus and process for manufacturing a brick or paver with a high content of coal ash (ranging from 60% to 100% coal ash or fly ash) so that a waste product (coal ash, and more particularly Class F coal ash) from a coal-fired power plant is incorporated into a building product (high content fly ash brick or paver). Also provided is a variable firing tray to support the dried, high content coal ash bricks/pavers as the dried products are sent through a tunnel kiln, to improve circulation around the individual bricks/pavers and thereby result in reduced firing time in the kiln.

A solar heat-reflective roofing product includes a base sheet, and solar heat-reflective roofing granules on top of the base sheet. The granules have a base particle with a flake-like geometry covered by a uniform coating layer. The coating layer has a thickness of at least one mil and includes a coating binder and at least one solar heat-reflective pigment. The solar heat-reflective pigment provides a solar heat reflectance of greater than 70 percent to the granules and the roofing product. Roofing products including roofing shingles and roofing membranes are described.

A method of producing alumina having a low soda content and excellent sintering properties includes the steps of adding a soda removal agent to alumina source material and calcining the alumina source material in a calciner (2), using a dust collector (5) to collect calcined alumina source material dust contained in the exhaust gas, discharging a portion of the collected dust out of the system, slurrying another portion of the collected dust in a slurrifier (10) while controlling slurry pH, washing and filtering the slurried dust and recirculating it back to the calciner, recirculating still another portion of the collected dust together with a mineralizing agent to the calciner, and removing the low soda alumina after the calcination.
