Osmosis evaporation separation recombination white spirit

A process for improving the quality of novel alcohol by permeation, evaporation, separation and reforming relates to application of separation technique with pervaporation membrane in the field of alcohol. The technique of the invention is that raw material alcohol is maintained in constant relatively low temperature, the liquor is transferred to a silastic composite membrane device by a pump and the liquor conducts circular flow in the upper reaches of the membrane, the lower reaches of the membrane is maintained in vacuum state by a vacuum pump, ethanol and volatile flavoring substances are selectively separated by pervaporation and turn into permeation vapor, representative mouth feeling and flavoring substances are reformed or concentrated in vapor, a low temperature condenser is equipped in the lower reaches of the membrane, condensed liquor with different components quantity of mouth feeling and flavoring substances is achieved by time steps of condensing of the permeation vapor, the liquor made by time steps of condensing is reformed and novel alcohol with high quality is blended. The process has the advantages of simple technological process, compact equipment, high maneuverability, short treatment period, which can develop novel alcohol with low cost and poor quality into novel alcohol with high price and good quality.

Preparation method of gel type strong-base anion exchange resin

The invention discloses a preparation method of gel type strong-base styrene anion exchange resin. The gel type strong-base styrene anion exchange resin disclosed by the invention is prepared by taking styrene, divinyl benzene, benzoyl peroxide, polyvinyl alcohol, gelatin, methylene blue, dichloromethane, 1,4-dichloromethoxybutane, anhydrous stannic chloride and trimethylamine as main raw materials through suspension polymerization reaction, chloromethylation reaction and amination reaction. The preparation method disclosed by the invention comprises the following steps of carrying out suspension polymerization reaction to synthesize a styrene-divinyl benzene cross-linked polymer, carrying out chloromethylation reaction of the styrene-divinyl benzene cross-linked polymer, and carrying out amination reaction of a chloromethylated styrene-divinyl benzene cross-linked polymer. The particle size range of the resin prepared by the method is 0.5-1.5 mm; the resin has a good property of removing sulfate and nitrate, a relatively high regeneration rate and the like; various physicochemical properties of the resin are good. Therefore, the resin disclosed by the invention can be applied in the sulfate and nitrate removing treatment process of water, and has good development prospects and practical significance.

Functional low-gram-weight cigarette paper and preparation method thereof

The invention relates to functional low-gram-weight cigarette paper, wherein the body phase thereof contains cut tobacco fibres or a first tobacco powder, a second tobacco powder is attached to the outer surface of at least one side of the body phase, and the first tobacco powder is the same as or different from the second tobacco powder. The invention further relates to a preparation method of the functional low-gram-weight cigarette paper. The preparation method comprises the following steps: (1) preparing paper pulp; (2) preparing special suspension stabilizing fluid for cigarette paper coating; and (3) making paper by a paper machine. The functional low-gram-weight cigarette paper disclosed by the invention is uniform in colouring and capable of improving the non-transparency of the cigarette paper; moreover, the functional low-gram-weight cigarette paper is good in stiffness and beneficial to roll; meanwhile, the functional low-gram-weight cigarette paper is good in ash wrapping force and capable of improving the smoking feeling of cigarettes. The functional low-gram-weight cigarette paper disclosed by the invention is also capable of effectively improving the sensory quality of the rolled cigarette produced during a smoking process and reducing harmful ingredients in the smoke of the cigarettes. Therefore, the functional low-gram-weight cigarette paper disclosed by the invention has a wide application prospect.

Preparation method for antibacterial melt-blown non-woven fabric

The invention relates to the technical field of non-woven fabrics, and provides a preparation method for an antibacterial melt-blown non-woven fabric. The preparation method comprises the following steps of (1) carrying out oxygen plasma treatment on a polypropylene non-woven fabric, and carrying out graft modification on the polypropylene non-woven fabric to prepare a modified polypropylene non-woven fabric; (2) polymerizing an amino-terminated hyperbranched polymer with propylene diamine and methyl methacrylate as raw materials, and preparing a modified hyperbranched polymer through polycondensation of carboxymethyl chitosan and the amino-terminated hyperbranched polymer; and (3) adding a copper chloride solution into a modified hyperbranched polymer aqueous solution, dropwise adding a sodium borohydride solution under nitrogen protection and ice bath conditions, carrying out impregnation treatment on the modified polypropylene non-woven fabric in the modified hyperbranched polymer aqueous solution after the reaction is finished, and drying to obtain the antibacterial melt-blown non-woven fabric. The preparation method solves a problem that the melt-blown non-woven fabric in theprior art only has an efficient filtering effect and does not have antibacterial property.
