A method of making a rapid setting composition for cement boards is disclosed. Compositions including a hydraulic cement preferably portland cement, an alkali metal citrate such as tripotassium citrate, and a phosphate such as sodium trimetaphosphate, with optional gypsum, and no alkanolamine accelerant, and no fly ash based cement. An interaction between the alkali metal citrate and the phosphate increases the effectiveness of accelerating reactions of the portland cement without need for an alkanolamine accelerant, even in the presence of gypsum. This allows unexpected quick setting and increased early-age compressive strength without shrinkage in the cement board compositions.

A silver-coated copper powder obtained by coating the surfaces of a copper powder, obtained by an atomization process or the like, with a silver-containing layer comprising 5 mass% (with respect to the silver-coated copper powder) of silver or a silver compound is added to a silver support liquid comprising a silver potassium cyanide solution (or a silver potassium cyanide solution to which is added at least one or more compounds selected from the group consisting of potassium pyrophosphate, boric acid, potassium citrate monohydrate, anhydrous citric acid, and L-aspartic acid), and 0.01 mass% or more of silver (with respect to the silver-coated copper powder) is supported on the surfaces of the copper powder coated with the silver-containing layer.

The invention relates to the field of composite crop fertilizers, and in particular relates to a high-fertility sustained-release composite fertilizer special for sugarcane planting. The composite fertilizer is prepared from the following raw materials in parts by weight: 15-18 parts of wheat bran, 6-8 parts of black humic acid, 8-10 parts of humic acid, 10-12 parts of mushroom stem, 8-10 parts of agrocybe cylindracea stem, 12-15 parts of sorghum straw, 3-5 parts of decomposed coal, 5-6 parts of sweet potato powder, 25-30 parts of peat soil, 6-8 parts of cellulose ether, 4-5 parts of starch ether, 3-5 parts of sodium tetraborate, 1-2 parts of silicon oil, 0.1-0.2 part of taurine, 2-4 parts of glutamine, 1-3 parts of black alum, 0.2-0.3 part of Twain 80, 6-8 parts of cane shoot shell, 10-12 parts of potassium metabisulfite, 15-18 parts of waste kelp residue, 12-15 parts of citric acid tripotassium and 3-5 parts of additives. According to the composite fertilizer provided by the invention, organic carbonized powder with an adsorption property is mixed with an organic fermentation liquid, medium trace elements and additives, a function of immobilizing nutrients is achieved, a sustained-release fertilization effect is achieved through a sustained-release filming agent, and the composite fertilizer is long lasting and efficient in fertilizer efficiency, the absorption and utilization rate of crops on the nutrient is high, plants are thick and solid and high in sweetness, and the planting benefits are improved.

The invention provides a preparation method of small-sized nanosilver for water-based conductive printing ink, and relates to the technical field of preparation of nanosilver. According to the preparation method provided by the invention, one of trisodium citrate, tripotassium citrate, carboxymethyl cellulose, sodium dodecyl sulfate and chitosan is added as a nucleation promoting stabilizer A, andone of polyglutamic acid, polyacrylic acid, polymethylacrylic acid, polyoxypropylene and polyacrylamide is added as a water-soluble organic protective agent B, so that caking of the nanosilver can beeffectively inhibited; nanosilver particles prepared through the preparation method are small in size and uniform in distribution, and the caking cannot be caused after long-term storage; the contentof an organic cladding agent on the surfaces of the nanosilver particles is less, and high conductivity can be realized; during preparation of the water-based conductive printing ink, the nanosilvercan be quickly and fully dispersed in a waterborne solvent, has excellent dispersity and can be applied to the technical field of ink jet printing.

The invention relates to a preparation method of an edible and nutrient composite fruit-vegetable coating preservative. The method comprises the following steps: adding pectin into deionized water so as to prepare a pectin solution; adding whey protein into the deionized water so as to prepare a whey protein solution; mixing the pectin solution with the whey protein solution; stirring and emulsifying; adding a plasticizer, tripotassium citrate anhydrous and calcium propionate; stirring; and performing vacuum degassing so as to prepare the composite coating preservative. The method is simple, strong in operability and low in cost; and the coating preservative is rich in nutrition. A preservative film prepared from the coating preservative is good in stability, high in strength and good in water resistance and has a good effect for inhibiting spoilage microorganisms so as to prolong the shelf life of fruits and vegetables.

The invention discloses a preparation method of an alkali-resistant water-based metal exterior wall coating, which comprises the following steps: (1) adding cerium chloride and yttrium chloride into water, mixing and stirring evenly, and heating it to 75-85°C Afterwards, continue to add sodium erucate to it, mix and stir evenly, and heat preservation treatment to obtain an alkali-resistant additive; (2) Pure acrylic emulsion, water, polyglycerol monostearate, tripotassium citrate, cyclohexyl Calcium sulfamate, alkali-resistant additives, metallic pigments, wetting and dispersing agents, and defoamers are uniformly mixed, and then stirred continuously to obtain finished products. The preparation method of an alkali-resistant water-based metal exterior wall paint provided by the present invention has wide sources of raw materials and low cost, and the prepared water-based metal exterior wall paint has good construction performance, no obstacles for two coats, water resistance, and scrubbing resistance Excellent performance, especially excellent alkali resistance and long service life.
