The higher fatty acid metallic salts may contain at least one kind of fillers selected from the group consisting of silica, alumina, tungsten disulfide, molybdenum disulfide, graphite fluoride, graphite, boron nitride, polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene (ETFE), and polyvinylidene fluoride (PVDF).

Moldings are disclosed for use as a catalyst or catalyst support for hydrating olefin, such as ethylene and propylene. The moldings are based on a pyrogenically produced mixed oxide having the following physicochemical parameters:The moldings are produced by homogenizing pyrogenically produced mixed oxide as desired with water and one or more compounds selected from the group of methylcellulose, methylhydroxyethylcellulose, wax, polyethylene glycol, magnesium stearate or aluminium stearate; drying the product at a temperature of 70-150° C.; optionally comminuting to yield a powder; optionally compression molding the powder to yield moldings; and performing heat treatment for a period of 0.5 to 10 hours at a temperature of 400 to 1200° C. Prior to drying, the mixture may also be subjected to kneading and / or shaping processes and extruded.

The invention discloses a preparation method of fly ash based zeolite / alumina composite adsorbing material, which comprises the following steps: metal lye solution and fly ash are mixed to be subjected to hydrothermal synthesis reaction; soluble aluminum stearate solution is continuously added in the mixture of the synthetic zeolite and waste lye liquor under stirring drop by drop, after solid-liquid separation, the solid phase is subjected to heat treatment to obtain zeolite / alumina composite adsorbent material, and the remaining solution is used to the preparation of lye solution in the subsequent synthesis process. According to the preparation method of the fly ash based zeolite / alumina composite adsorbing material, the waste lye liquor generated during the zeolite synthetizing with fly ash is changed into alumina, so that the long-standing unsolved problems that waste lye produced when the fly ash is used as raw material to produce zeolite cannot be treated, and the zeolite product has strong basicity can be solved, and the prepared zeolite / alumina composite adsorbing material has more efficient adsorption effect on nitrogen and phosphorus nutrients in the water, so the treatment of wastes with processes of waster against one another can be achieved; and the synthesis process is simple, and the cost is low.

The invention relates to a biomimetic liquid lubricating agent for drilling fluid and a preparation method thereof. The biomimetic liquid lubricating agent is prepared from the following raw materials including oleic acid, emulsifiers, glycerol, epoxy propane and antifoaming agents, wherein the emulsifiers are one or several materials selected from triethanolamine, aluminum stearate and span-80. The preparation method comprises the following technical steps of weight the raw materials of the oleic acid, the emulsifiers, the glycerol and the epoxy propane; adding the raw materials into a reaction kettle so that the raw materials are sufficiently mixed, and a mixed material is obtained; performing an esterification process on the mixed material at the esterification temperature of 200 to 250 DEG C for the esterification time being 1 to 3h; performing cooling to obtain an esterification product; performing an emulsification process on the esterification product at the emulsification temperature of 80 to 100 DEG C for the emulsification time being 1 to 2h; lowering the temperature of a product after completing the emulsification process; adding the antifoaming agents so that the materials are sufficiently and uniformly mixed; discharging the materials after the temperature is lowered to room temperature. The biomimetic liquid lubricating agent can resist high temperature being 200 DEG C or higher; the friction coefficient of the drilling fluid can be reduced; the adhesion coefficient of the drilling fluid can also be reduced; the fluorescence grade is low.

The invention discloses a permeation crystallizing waterproof dry powder coating for concrete and a preparation method. The preparation method comprises the following steps of a, adding microcrystalline cellulose, bentonite, white alum and potassiam polyoxyethylene laurylether phosphate into water, mixing, grinding, and spray-drying, so as to obtain nanometer composite microspheres; b, mixing andstirring nanometer silicon micropowder, aluminum stearate, and a redispersible latex powder, so as to obtain the coated nanometer silicon micropowder; c, uniformly dispersing the nanometer composite microspheres, the coated nanometer silicon micropowder, a large-size mica powder, and methyl sodium silicate, so as to obtain the permeation crystallizing waterproof dry powder coating for the concrete.
