The present invention provides a method for obtaining high-purity and high-stability recombinant human albumin, wherein medium-long-chain fatty acid ligands are added and proteins of charge heterogeneity are removed through anion and / or cation chromatography. An inventiveness of the present invention is that the mixed solution contains a fatty acid mixture and poloxamer, and the molar ratio of oleic acid, myristic acid, sodium palmitate, sodium stearate to recombinant human albumin is 0.3:0.3:0.3:0.5:1. Sequential use of ion exchange chromatography can effectively remove truncated albumins, mismatched or modified albumins from recombinant albumins, to remove albumins of charge heterogeneity and modified albumins, to obtain high-purity and high-stability human albumin.

The application provides an environment-friendly brick and a preparation process thereof, wherein the environment-friendly brick comprises the following raw materials in parts by weight: 2-5 parts of sludge, 90-95 parts of construction waste, 0.1-0.3 parts of a composite sintering aid, and 0.5-1.2 parts of a plasticity adjusting agent. The composite sintering aid is composed of silicon nitride, starch, vegetable oil and sodium alginate. The plasticity adjusting agent is one or a combination of several of sodium palmitate, sodium stearate and sophoricoside. The environment-friendly brick is prepared through S1 raw material preparation, S2 raw material mixing and aging, S3 plasticity adjustment, S4 molding and cutting, and S5 drying and sintering. The application promotes complete combustion of the sludge by adding the composite sintering aid, thereby enhancing the performance of the brick body. By adding the plasticity adjusting agent and setting the plasticity adjusting link, the viscosity and fluidity of the material are adjusted according to the molding requirements of the brick body, the performance of the brick body is improved, and the molding defects are reduced.

The invention provides a combined collecting agent for flotation of scheelite and application of the combined collecting agent, the combined collecting agent comprises a main collecting agent and an auxiliary collecting agent, and the molar ratio of the main collecting agent to the auxiliary collecting agent is 1: (1-3); the main collecting agent is at least one of alkyl glycoside, sodium oleate, benzohydroxamic acid, oxidized paraffin soap, lauryl sodium sulfate, sodium laurate, sodium palmitate and sodium stearate; and the auxiliary collecting agent is at least one of alkyl dimethyl betaine, sulphobetaine, phosphate betaine, octadecyl betaine, cocoyl propyl betaine and coconut oil dimethyl betaine. The two collecting agents with different properties are combined for use, so that the scheelite selectivity can be remarkably improved, and the flotation separation effect of the scheelite and associated gangue of the scheelite is enhanced.

The invention discloses a water-retaining agent suitable for outdoor pepper planting as well as a preparation method and application thereof, and the water-retaining agent comprises the following components in parts by weight: 5-12 parts of a sodium lignin sulfonate grafted N-vinyl pyrrolidone copolymer, 3-5 parts of 3-indoleacetamide, 2-4 parts of a cross-linking agent, 2-3 parts of modified carboxymethyl chitosan and 2-3 parts of diatomite. According to the water-retaining agent provided by the invention, through the synergistic effect of the sodium lignin sulfonate grafted N-vinyl pyrrolidone copolymer, the 3-indoleacetamide, the cassava starch-sodium palmitate compound cross-linking agent, the modified carboxymethyl chitosan and the diatomite, the functions of slowly releasing and controlling moisture, promoting the growth of peppers and improving the soil structure are realized; the core requirement of outdoor pepper planting is met.

This invention relates to the field of oil and gas field chemical agent preparation technology, and particularly to a sulfur deposition inhibitor for high-sulfur gas fields and its preparation method. The sulfur deposition inhibitor of this invention comprises the following components in parts by weight: 0.9-1.5 parts hexadecyltrimethylammonium chloride, 0.3-0.6 parts octadecyltrimethylammonium chloride, 4-6 parts cocamidopropyl betaine, 2.5-3.5 parts sodium α-alkenyl sulfonate, 1.5-2.2 parts sodium palmitate methyl sulfonate, 1.2-1.8 parts potassium carbonate, 0.6-1 parts magnesium chloride, and 83.4-89 parts solvent. This invention solves the problems of complex synthesis processes, low inhibition efficiency, high toxicity, and poor engineering adaptability of traditional sulfur inhibitors by adjusting the synergy and compatibility between inorganic salts and surfactants, making it suitable for large-scale application and promotion in high-sulfur gas fields.
