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.

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 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.
