The invention relates to a combined type exhibition board easy to assemble and disassemble. The combined type exhibition board comprises a protective sleeve, a hexagonal tensioning lock, bearing reinforcing groove ribs, a groove connecting piece, a U-type edge sealing piece, a convex groove connecting piece, an adjusting base, an A-type buckle plate stand column, a connecting shaft, a B-type buckle plate stand column, a partition plate supporting piece, a hook and a partition plate. The exhibition board is a micro-foaming plastic hollow board. A hexagonal tensioning lock hole, a circular hole and a rectangular groove are formed in the exhibition board. The combined type exhibition board has the advantages that the structure is portable, installation is easy, the appearance is attractive, the combination is flexible, the assembled exhibition room wall can extend to form an exhibition shelf and the hook, and the combined type exhibition board particularly meets the individualized development requirement of the current exhibition industry.

The invention relates to a purification process for preparing high-purity coenzyme Q10 from crude coenzyme Q10 extracts obtained from thallus fermentation, which belongs to the technical field of compound separation purification. The purification process is characterized by sequentially comprising the following steps of: carrying out adsorbent resin adsorption, elution, concentration, crystallization and recrystallization on the crude coenzyme Q10 extracts; then, carrying out chromatography on a silicagel column; and purifying and refining by using a petroleum ether -aether or normal hexane-ethyl acetate mixed solvents as eluant. The invention has the following advantages that by adopting an adsorbent resin, good adsorption performance can be exerted on the coenzyme Q10, the desorption operation is simple, the stability is good, and the adsorbent resin can be reused many times; and by combining the adsorbent resin with the silica gel chromatography method, the silica gel utilization rate is high, the required silica gel is low quantity and can maintain good purification effect after being reused more than 10 times, the waste quantity of the silica gel is small, and the solvents can be recycled so that the purpose of environment protection is achieved. The production operation is simple and convenient, and the purity of the obtained coenzyme Q10 is higher than or equal to 98 percent.

The invention discloses a preparation method of grease with a humanized structure. The preparation method comprises the following steps: carrying out intra-molecular rearrangement reaction to palm oil with palmitic acid content of higher than 50% under the action of catalyst to obtain Sn-2 locus triglyceride with palmitic acid content of higher than 50%; and carrying out ester exchange reaction to the Sn-2 locus triglyceride with palmitic acid content of higher than 50% with mixed fatty acid or non-glyceride under the action of 1,3 locus Specificity lipase, and then subjecting the reaction product to after treatment, so as to obtain the grease with humanized structure, wherein the mixed fatty acid is mixture of at least two selected from the group consisting of decanoic acid, lauric acid, myristic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid and linolenic acid. The vegetable oils are used as the raw material according to the method, so the safety is high; the preparation process is simple, the reaction time is short, the enzyme dosage is low, and the cost is low; and the prepared grease with the humanized structure is very similar to the beast milk fat in the composition of fatty acid and the structural distribution of triglyceride, so the grease can be added in infant formula or formula foods and used as breast milk fat substitute.
