The invention discloses an antibacterial finishing agent, an antibacterial yarn and a preparation method and application of the antibacterial yarn. The antibacterial finishing agent is prepared from the following components in parts by weight: 5-20 parts of antibacterial agent, 5-25 parts of a cationic colouring stabilizer, 10-30 parts of a cationic softener and 10-30 parts of water-based resin, wherein the antibacterial agent is selected from at least one of N-dodecyl-amino glycine betaine-2-cysteamine hydrochloride, 3-trimethoxysilylpropyl octadecyldimethyl-ammoniu chloride, chitosan biguanidine hydrochloride, polyhexamethylene biguanidine hydrochloride and ammonium dihydrogen phosphate; and the water-based resin is selected from at least one of vinyl acetate emulsion resin, polyvinyl alcohol resin, polymethylacrylic acid and polyethylene oxide. The water-based resin adopting the components is capable of improving the hand feeling and the comfort of the yarn; and through common action of the cationic colouring stabilizer, the cationic softener, the water-based resin and the antibacterial agent at the ratio, the yarn has good antibacterial property, the requirements of performance, such as the color fastness and the hand feeling comfort are coordinated, and meanwhile, the antibacterial property, the color fastness and the comfort of the yarn are ensured.

The invention relates to the technical field of white spirit commodity quality detection, in particular to a microwave digestion graphite furnace atomic absorption analysis method for measuring tracelead in white spirit. The method comprises the following steps that: S1: carrying out sampling and digestion; S2: preparing matrix modifier solution; S3: preparing sample solution; S4: preparing reference substance solution; S5: preparing a lead standard curve; and S6: measuring the content of sample lead. The method has the beneficial effects that the mixed solution of citric acid, polysorbate 80, ammonium dihydrogen phosphate and palladium nitrate is taken as the matrix modifier, a reduction atmosphere is formed in the graphite furnace, lead oxide reduction is enhanced, a situation that background adsorption interference is generated due to matrix evaporation during high-temperature atomization is avoided, analysis accuracy is improved, the polysorbate 80 serves as the solubilizer of thematrix modifier solution, condensed phase interference and gaseous phase interference are lowered, and in addition, the capability of the matrix modifier on inhibiting lead element volatilization canbe improved.

The paint consists of two components A and B, wherein the component A consists of the following raw materials in parts by weight: 67-74 parts of epoxy resin E44, 20-25 parts of high chlorinated polyethylene resin, 10-16 parts of mica powder, 4-6 parts of titanium dioxide, 5-7 parts of sodium carboxy methyl cellulose, 4-6 parts dimethyl terephthalate, 4-6 parts of glycerol, 2-4 parts of ethyl acrylate, 2-3 parts of tung oil, 2-3 parts of polyacrylamide, 2-3 parts of diethylamine, 2-3 parts of triethyl O-acetylcitrate, 3-4 parts of ammonium dihydrogen phosphate, 4-5 parts of sodium molybdate, 2-4 parts of 2, 6-butylated hydroxytoluene, 9-12 parts of a compound modifying agent, 25-30 parts of dimethyl benzene, 8-10 parts of n-butyl alcohol, 0.8-1 part of anilino-methyl-triethoxysilane and 0.5-1 part of dimethicone. The produced paint has the advantages of good adhesion with metal, small structural pores, compact structure, excellent adhesion, good flexibility, high shock strength, strong corrosion resistance and efficient base metal protection function.

The invention belongs to the technical field of hydroponic planting, and particularly relates to a hydroponic planting nutrient solution suitable for a balcony and a preparation method and an application of the hydroponic planting nutrient solution. The hydroponic planting nutrient solution comprises a solution A and a solution B, wherein the solution A comprises calcium nitrate tetrahydrate, potassium nitrate, EDTA, EDDHA and water; and the solution B comprises potassium nitrate, magnesium nitrate, potassium sulfate, potassium dihydrogen phosphate, ammonium dihydrogen phosphate, manganese sulfate tetrahydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, boric acid, ammonium molybdate tetrahydrate and water. According to the nutrient solution, the pH value of the nutrient solution can be stabilized between 5.5 and 6.5 in the hydroponic planting process under the condition that the element content and the proportional relation in all the nutrient solutions are maintained, and the nutrient solution is suitable for growth and development of crops. According to the nutrient solution, the pH value does not need to be intervened through acid liquor and alkali liquor, the workload of planting personnel is relieved, and the problem that the acid liquor and the alkali liquor stored at home are not safe is solved.

The invention relates to organic-inorganic compound fertilizer containing baeckea frutescens bran and belongs to the agricultural production technique. Firstly, raw baeckea frutescens bran degreased at a high temperature is ground properly, and loose baeckea frutescens bran is obtained; urea, ammonium dihydrogen phosphate and potassium chloride are ground and screened; the baeckea frutescens bran and powdery inorganic compound fertilizer are sufficiently mixed and homogenized, and the loose organic-inorganic compound fertilizer containing the baeckea frutescens bran is obtained. By means of the baeckea frutescens bran subjected to high temperature sterilization treatment, the organic-inorganic compound fertilizer has the characteristics of being mould-proof, free of mixed bacteria, capable of being degraded naturally and non-toxic, and has good water retention and air permeability; root corrosion of plants is prevented, root growth of the plants is promoted, soil can be protected, and sliming is avoided.
