According to the formula of the kaolin and white afrodite mixed powder and a production process of the kaolinand white afrodite mixed powder, the white afrodite is added, and the white afrodite is a silicon natural rock which is formed by binding quartz sand with silicate minerals. The white afrodite is extremely rich in mineral resources and is abundant in Sichuan, Hubei, Guangxi and the like, mining is convenient, price is low, cost is low, and high transportation cost can be avoided due to abundant production in many places, so that production cost of glass fibers can be reduced. The kaolin is added, and the kaolin is clay and clay rocks which are common in nature and are mainly composed of kaolinite clay minerals. Mixed glass fiber powder components of the kaolin and the white afrodite are very close to pyrophyllite, so that the formula provided by the invention can be used to replace an original formula comprising pyrophyllite powder for carrying out fiber drawing operation, so that the glass fiber drawing operation rate is improved, pyrophyllite resources are saved, and an active promotion effect of reducing cost of glass fiber raw materials is achieved.

Disclosed herein is a composite material formed from an inorganic mesoporous, or mesoporous-like, material, including mesoporous silica, mesoporous carbon, mesoporous zinc oxide, bentonite and kaolinite clay that is dispersed throughout a polymeric matrix formed by a crosslinked polymer. The crosslinked polymer has acidic- or basic-residues, wherein the basic residues are formed from a monomeric material with at least one ethylenic bond and an amide functional group (e.g. acrylamide), and the acidic residues are formed from a monomer material with at least one ethylenic bond and a carboxylic acid functional group (e.g. acrylic acid). Said composite material may also optionally have further acidic- or basic-residues grafted onto the inorganic mesoporous material. The resulting composite material may be used to remove acidic or basic impurities from a gas in need thereof and can be easily regenerated.

Methods for preparing metakaolin-enhanced industrial minerals. Mixing and heating kaolinite clay with an industrial mineral, such as activated carbon, that is between 750° F. and 1400° F. results in a metakaolin / activated carbon complex that provides good mercury sorbent qualities while producing a fly ash (after use as a sorbent in emissions applications) that has a lower foaming index.
