The invention belongs to the technical field of water treatment in water pollution prevention and control, and relates to the treatment of dye wastewater, in particular to a method for treating dye wastewater by utilizing modified straws. The method comprises the following steps of performing straw modification by virtue of a two-step method, namely pre-treating rice straws by virtue of sodium hydroxide, and performing modification reaction on the pre-treated rice straws and tetradecyl trimethyl ammonium chloride; removing orange yellow II, methylene blue and eriochrome black T dyes from a water body to finally realize the treatment of the dye wastewater by virtue of the modified straws. The modified rice straws and tetradecyl trimethyl ammonium chloride are subjected to mixed reaction according to a mass ratio of 1:1 to 1:1.5; the content of sodium hydroxide is 10 to 30 mass percent. According to the technical scheme, the good coagulation effects, high decolorization capability and convenience in use are achieved, and the cost is lowered; agricultural straws can be recycled, and meanwhile, the dye wastewater can be decolored.

A process for preparing a low water absorption epoxy resin type packaging material comprises the following steps: (1) taking 5 g of clay and 2.5 g of tetradecyl trimethylammonium chloride to prepare lipophilic organic modified clay; (2) adding 1g of bisphenol A diglycidyl ether and a proper amount of the clay, then adding 5 g of N, N-dimethylacetamide, then adding 1, 3-bis(3-aminopropyl)-1, 1, 3, 3-tetramethyldisiloxane, and forming a film at 120 DEG C for 5 hours. The packaging material prepared by the method can prolong water through time and effectively reduces water absorption rate because that water through paths are more winding due to layered arrangement of the clay dispersed in epoxy resin material.

The invention provides a low-foam high-efficiency water-base detergent and a cleaning method. The low-foam high-efficiency water-base detergent is prepared from the following raw materials in percentage by mass: 6-12% of a surfactant, 0-0.1% of a corrosion inhibitor, 0-0.5% of a defoaming agent and the balance of deionized water, wherein a nonionic surfactant is prepared from any one, two, three or four of fatty alcohol-polyoxyethylene ether, Tween-20, alkylphenol polyoxyethylene 9-ether and triethanolamine through mixing in a respective mass ratio greater than 0%; and a cationic surfactant isprepared from any one, two or three of hexadecyl trimethyl ammonium chloride, tetradecyl trimethyl ammonium chloride and dodecyl trimethyl ammonium chloride through mixing in a respective mass ratiogreater than 0%. Together with a cleaning process, the detergent is capable of strongly removing surface residues after welding of a rosin type welding flux, a welding point is kept bright, and good surface insulation is achieved; and the detergent is low in volatilization in the cleaning process, free of pollution substance which can affect health of operators, and in addition free of bubble in the cleaning process.

A method of servicing a wellbore comprising placing downhole a composition comprising a surfactant package comprising a cationic surfactant and anionic surfactant, wherein the surfactant package when contacted with an aqueous solution forms a viscosified composition in the presence of less than about 30 wt. % of a hydrotrope.

The invention discloses an organic fertilizer capable of improving the heat resistance of plants and the absorption capacity of root systems. The organic fertilizer is prepared from, by weight, 36-38 parts of sesame meal, 18-20 parts of needle mushroom dregs, 1-2 parts of fumed silica, 2-3 parts of oxidized starch, 0.8-1.0 part of sodium selenite, 2-3 parts of potassium chloride, 2-3 parts of a paecilomyces lilacinus inoculant, 38-42 parts of rice straw, 28-30 parts of cinnamomum camphora leaves, 10-11 parts of a hydrogen peroxide solution with the concentration of 30%, 1.0-1.4 parts of trimethyl tetradecyl ammonium chloride, an appropriate amount of a sodium hydroxide solution with the concentration of 5 mol / L, an appropriate amount of an ethanol water solution with the concentration of 45% and an appropriate amount of water. According to the fertilizer, the adopted raw materials have the diverse types and can well contain various nutritional ingredients needed by plant growth; meanwhile, the nutrients are fixed near the root systems through fertilizer particles, and therefore growth of the root systems can be effectively induced; by adding the bacterium inoculant into the fertilizer, expansion of hyphae outside plant roots can be promoted, the effective absorption area of the root systems is increased, accumulation of the plants to nutrient substances is enhanced, the biomass is increased, and a positive promotion effect on yield increasement and quality improvement is achieved.

The invention discloses a compound gas hydrate anti-agglomerant and an application thereof. The anti-agglomerant is prepared by compounding a polyalcohol nonionic surfactant and a quaternary ammonium salt compound, wherein the polyalcohol nonionic surfactant is one or a combination of more of span-20, span-40, span-60, span-65, span-80 and span-85; and the quaternary ammonium salt compound is one or a combination of more of tetrabutylammonium bromide, tetraamylammonium bromide, dodecyltrimethylammonium bromide, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, cetyltrimethylammonium chloride, dioctyldimethyl ammonium chloride and didecyldimethyl ammonium chloride. The anti-agglomerant is applied to a separation process of a mixed gas by a water / oil emulsion system in the conditions of mixed transportation of an oil-gas-water three-phase system and hydrate generation. Under the influence of supercooling degree and operation conditions, the compound gas hydrate anti-agglomerant disclosed by the invention has the advantages of small dosage, good performance, economy and environmental friendliness, wide application range, good recycling property and the like and has a broad market prospect.

A cutting fluid with high cooling speed is prepared by the following raw materials in parts by weight: 20-23 parts of mineral oil, 3-4 parts of alkylphenol ethoxylates phosphate, 4-5 parts of stearyl alcohol based polyoxyethylene ether, 6-7 parts of polyisobutene, 2-3 parts of adipic acid, 1-2 parts of crystalline flake graphite, 2-3 parts of tetradecyl trimethyl ammonium chloride, 1-2 parts of tin sulfate, 6-8 parts of assistant and 200 parts of water. With the adoption of the crystalline flake graphite, the cutting fluid has excellent lubricity and extreme pressure property, and good heat-conducting property; the cooling speed of the cutting fluid is increased; with the adoption of the tin sulfate, the cutting fluid is good in stability and stable in viscosity; and the cutting fluid has good rust resistance and cleaning property, does not corrode a workpiece, increases the cutting speed and reduces tool wear.
