The present invention discloses one kind of organic fertilizer and its preparing process, and belongs to the field of organic fertilizer. The organic fertilizer is prepared with papermaking black liquor and wheat bran as material and through inoculation, anaerobic acidifying and twice composing. The organic fertilizer has organic matter as main component, and has the obvious effects of promoting crop growth, raising ventilation of soil, preserving fertilizer and water.

The invention relates to a weakly polar paper filter material and preparation and application methods thereof, belonging to the technical field of preparation of cigarette filter sticks. The paper filter material comprises 2-50 percent of weakly polar chemical fiber, 0.1-3 percent of polarity regulating aid and the balance of natural plant fiber such as wood pulp fiber, jute pulp fiber and the like. The invention has the advantages: the overall polarity of the cigarette paper filter material is lowered, so that the smoking taste of paper filter material cigarettes is improved remarkably; and moreover, the method has high process reliability and is easy for realizing industrial production.

The invention relates to the preparation of coatings, and aims to provide a method for preparing hydrophobic nano-modified resin composite coatings for LED substrates. The method comprises: first uniformly dispersing nanometer α-Al2O3 and butanol; then adding silane coupling agent KH560 for aging to obtain modified α-Al2O3 sol, concentrated distillation; tridecafluorooctyltriethoxysilane, n- Mix butanol and formic acid, add deionized water, and age to obtain fluorosilane oligomer sol; mix the first two products, epoxy resin monomer, methyl ethyl ketone, xylene and 2,2,4-trimethyl- 1,3‑Pentanediol monoisobutyrate is dispersed to give a coating. The present invention introduces α-Al2O3 nanoparticles into the traditional epoxy resin coating to improve the thermal conductivity of the resin, while retaining the excellent coating and processability of the resin to the greatest extent, and the price is relatively good. The hydrophobic performance is significantly improved, which reduces the problem of short circuits caused by humid air. It is suitable for production and processing on existing production lines, and is a beneficial improvement to traditional epoxy resin-covered aluminum substrates.

The invention belongs to the technical field of medicine preparation, and relates to a method for preparing a three-vitamin cod-liver oil emulsion by extracting the vitamin C to an emulsifying layer from a water phase of the emulsion. The preparing method includes the technical steps of preparing a soyabean lecithin solution, preparing phosphatide micro-capsules and emulsifying, wherein soyabean lecithin is added into absolute ethyl alcohol and completely dissolved through stirring to obtain a soyabean lecithin solution; the vitamin C is put into a boiling drying bed, and the soyabean lecithin solution is sprayed into the boiling drying bed to obtain vitamin C soyabean lecithin micro-capsules after drying; cod-liver oil, the vitamin A and the vitamin D are dissolved in soybean oil through mixing and stirring, the vitamin C soyabean lecithin micro-capsules and purified water are sequentially added and evenly stirred, and then reverse tangent emulsifying is carried out to obtain the three-vitamin cod-liver oil emulsion finished product. The preparing technology is mature in route, and the three-vitamin cod-liver oil emulsion is rich in nutrient, good in mouthfeel and taste, low in processing cost, safe and reliable.

The invention discloses a method for preparing cigarette filter rods by Lyocell bundles and belongs to the technical field of cigarette filter stick manufacturing. According to the method for preparing the cigarette filter rods by the Lyocell bundles, Lyocell filaments are subjected to primary bundling to be fibrillated and then subjected to secondary bundling and curved to form the Lyocell bundles for manufacturing the cigarette filter rods. The method has the advantages that the Lyocell filaments after being fibrillated is remarkably higher in cigarette tar reducing capability and can be further used for manufacturing the cigarette filter rods, and the method is simple in processing route, controllable in fibrillation degree, low in cost and easy to achieve industrial production.

The invention belongs to the field of beer brewing technology and in particular relates to a method for preparing health-care purple sweet potato beer. The method comprises the processes of purple sweet potato juice preparation, wort preparation and mixed fermentation; specifically, the method comprises the steps of cleaning mud and sands and fungi outside purple sweet potatoes with a citric acid aqueous solution, feeding the cleaned purple sweet potatoes into a steam oven to be steamed, cooling, saccharifying with a conventional process, carrying out enzyme deactivation on saccharified purple sweet potato sauce, squeezing by conventional extruding equipment, and filtering to obtain normal juice of the purple sweet potatoes; crushing malts, adding water for mash gelatinization, saccharifying, carrying out grain raking, standing, refluxing and grain washing, adding hop into a mash kettle, clarifying, and cooling to obtain wort; and adding the normal juice of the purple sweet potatoes during post fermentation in wort beermaking, fermenting, cooling, filtering and clarifying to obtain the health-care purple sweet potato beer. The process route is ripe, the production cost is low, the prepared purple sweet potato beer is rich in nutrition, is fresh and cool, has pure aroma and beer function and taste, and also achieves the health-care effect.
