3027 results about "Talc" patented technology

Talc is a clay mineral composed of hydrated magnesium silicate with the chemical formula Mg₃Si₄O₁₀(OH)₂. Talc in powdered form, often in combination with corn starch, is widely used as baby powder. This mineral is used as a thickening agent and lubricant, is an ingredient in ceramics, paint and roofing material, and is also one of the main ingredients in many cosmetic products. It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavage, uneven flat fracture and it is foliated with a two dimensional platy form.

Production method of once-fired super-spar ceramic tile and ceramic tile

The invention relates to a production method of once-fired super-spar ceramic tile and the ceramic tile. The production method of the once-fired super-spar ceramic tile comprises the following steps: preparing green body powder; pressing a tile body; cleaning the green body; pouring ground glaze; printing; pouring overglaze; firing a glaze body at a high temperature; polishing; performing surface treatment; performing edge polishing; and packaging to obtain a finished product, wherein the overglaze comprises the following components in parts by weight: 5 to 13 parts of quartz powder, 3 to 20 parts of potassium feldspar, 20 to 28 parts of soda feldspar, 12 to 18 parts of dolomite, 3 to 6 parts of fired talc, 3 to 8 parts of kaolin, 14 to 22 parts of calcined kaolin, 3 to 8 parts of zinc oxide, 7 to 14 parts of barium carbonate and 3 to 6 parts of grammite. According to the invention, the problems that microlite has low wear resistance and is difficult to process in the prior art are solved, and the defect of water ripples caused by the situations that fully-polished glaze absorbs dirt, bottom is easy to expose and the tile surface is uneven is also solved. The super-spar product produced with the method has the advantages that the microlite is transparent, bright and smooth like a mirror and does not absorb dirt completely; and the fully-polished glaze is light, thin and wear-resistant.

Separation of hydrocarbons from hydrocarbon containing liquid

A novel filtration media employing polymeric absorbents comprising a material selected from the group consisting of styrene, pentadiene, cyclopentadiene, butylene, ethylene, isoprene, butadiene, propylene and mixtures thereof; and a filtration enabler intimately mixed with the polymeric absorbent. Preferably, the filtration enabler comprises clay, ground glass, talc, mica, recycled rubber, sand, gravel, vermiculite, recycled plastic chips, an inert, non-absorbent material, or mixtures thereof. Preferably, the polymeric absorbent may be further compounded to incorporate about 10 to 50% recycled or waste plastic scrap, scrap polyolefins, inorganic fillers, or other inexpensive, relatively inert solids. Other compounding materials may include clay, talc, mica, ground glass, silica, and mixtures thereof. Upon contact with a hydrocarbon containing liquid, the liquid partially dissolves the polymeric absorbent forming a partial filtration barrier prior to the filtration media substantially absorbing the hydrocarbons, and allowing hydrocarbon-free liquid to flow through the filtration media. In situations of a leak or spill wherein an excess of hydrocarbons are present, the filtration media forms a plug to seal and prevent further discharge of the hydrocarbons. The filtration media may be placed inside a portable container for insertion into an existing drain such that hydrocarbon containing liquid is filtered through the device allowing hydrocarbon-free liquid to flow from the device. The filtration media has a thickness within the container adapted to substantially filter out hydrocarbons while capable of forming a plug in an excess of hydrocarbons. The filtration media of the present invention may be employed in pits, pipes, and self-contained cartridges of various sizes to remove and contain hydrocarbons from a hydrocarbon containing liquid or a hydrocarbon spill or leak, and that the absorbent will form a plug in an excess of hydrocarbons entering the pit, pipe or cartridge. Also described are methods of filtering and preventing discharge of a hydrocarbon containing liquid.
