The invention relates to a preparation method of a polaroid adhesive and a preparation method of a polaroid. The preparation method of the polaroid adhesive comprises swelling polyvinyl alcohol in water to obtain an aqueous solution containing swollen polyvinyl alcohol, heating the aqueous solution containing the swollen polyvinyl alcohol to 90-100 DEG C under stirring, then adding a modifier intothe mixed solution, keeping the temperature of 90-100 DEG C for 40 to 60 minutes, cooling the mixture to 40 DEG C or less to obtain a pre-mixed solution, adjusting pH of the pre-mixed solution to 1.5-2 under continuous stirring, and adding dialdehydes, additives, a cross-linking agent and alcohol into the pre-mixed solution for a cross-linking reaction at the room temperature so that an adhesiveis obtained. The polaroid adhesive obtained by the preparation method has good adhesive properties and improves high temperature and yellowing resistance of a polaroid.

The invention relates to a ginseng and soapberry fermentation extract and its application in cosmetics. The extract is characterized by taking ginseng as the raw material, adding soapberries for lactobacillus fermentation, then conducting extraction with ethanol and other solvents, and purifying the extracting solution which can be applied in cosmetics. The fermented ginseng processed extracting solution and its cosmetics can be used for moisture retention, skin whitening, bacteriostasis, anti-senility, skin protection, and caring skin oxidative damage. As the extraction technology makes fully use of active substances in the ginseng and soapberry fermentation extract, such as rare ginsenoside Rh2, CK and the like, as well as the effective skin care effect of fermented soapberries, etc., the antioxidation and nutrition functions of ginseng and soapberry fermentation extract cosmetics are improved. The invention also provides embodiments of skin care cosmetics, and simultaneously elaborates that, compared with white ginseng, the ginseng and soapberry fermentation processed product of the invention contains different ginsenoside and has strong cosmetic application efficacy.

The invention provides an affinity chromatography column, a preparation method and application thereof, and relates to the technical field of separation and purification of biological macromolecules. The stationary phase of the above-mentioned affinity chromatography column is mainly prepared from the biological macromolecules containing amino ligands treated with a denaturant, a cyanogen bromide-activated agarose chromatography filler and a surfactant through a coupling incubation reaction. The above-mentioned affinity chromatography column can effectively promote the coupling of the amino ligand-containing biomacromolecule treated with the denaturant and the cyanogen bromide-activated agarose chromatography packing by adding a surfactant to the stationary phase, and effectively alleviate the problem. The problem of agglomeration and agglomeration of the cyanogen bromide activated agarose chromatography medium caused by the easy precipitation of the ligand after the denaturant treatment in the preparation process of the existing cyanogen bromide activated agarose affinity chromatography column is solved.

A kind of asphalt cleaning agent, according to mass percentage ratio, comprises following components: surfactant 6-10 parts, sherwood oil 55-65 parts, trichlorethylene 8-14 parts, isopropanol 4-8 parts, water 3 parts -7 parts, 3-7 parts of diethylene glycol ether, 3-7 parts of triethanolamine, a total of 100 parts; adopting the asphalt cleaning agent of the present invention can remove the asphalt on the asphalt oil stained container surface and construction machine surface in various asphalt test processes Dirt is easily washed off, and in addition, the cleaning agent can also be used for cleaning asphalt adhered to automobile bodies; the asphalt cleaning agent has fast cleaning speed, good cleaning effect, safe and reliable use, simple preparation process, and low production cost; The cleaning agent can be recycled and can be widely used in asphalt cleaning on the surface of various mechanical equipment and experimental instruments such as asphalt production, user units and college laboratories.

The invention discloses a photosensitive dry film which sequentially comprises a PET (Polyethylene Terephthalate) support film layer, a photosensitive resin layer and a PE (Polyethylene) protective film layer, wherein the photosensitive resin layer mainly comprises the following materials in parts by weight: 60-70 parts of alkali-soluble resin, 15-25 parts of a polymerizability compound with at least one ethylene unsaturated base, 1-2 parts of a photopolymerization initiator and 0.01-0.1 parts of deodorant. The deodorant can exert a solubilizing function on a low polymer in the photosensitive resin layer, and can inhibit volatilization of the low polymer, so that the photosensitive dry film can inhibit or eliminate the original distinctive odor in the photosensitive resin layer. After the deodorant is added, the performances, such as photosensitiveness, mechanical strength and resolving power of the photosensitive dry film are not affected.

The invention relates to an environment-friendly waste PE (polyethylene) material, a preparation method thereof, a modified environment-friendly waste PE material prepared from the environment-friendly waste PE material and a preparation method of the modified environment-friendly waste PE material, and belongs to the technical field of PE materials.
