The invention discloses a strengthening composite bamboo board and preparing method, which consists of net bamboo fiber bundle layer and surface layer, wherein the net bamboo fiber bundle layer is composed of parallel grain and cross grain. The invention is prior to wood fiber board, which prevents the common bamboo board (bar structure of multiple-layer parallel adhesion) from deforming and uneven strength.

The invention relates to a method for macrosegregation numerical simulation of a casting, aiming at solving the problems of long computation time, low precision and unsuitability for predication of castings with large size or complex shapes in the traditional macrosegregation. The method comprises the following steps of: performing mesh generation on a selected dendritic crystal growth microcosmic computation field; computing dendritic crystal growth shapes during alloy solidification under different maximum nucleation densities from a microcosmic scale, and outputting a solid phase fraction-average dendritic crystal solid phase feature diameter curve; performing macro-scale mesh generation on the casting; computing a mass, momentum, energy and composition conservation equation from a macrocosmic scale; computing a solid phase fraction by using a Newton downhill method; and computing a pasty zone permeability model from a macrocosmic scale by adopting a linear interpolation technologybased on the solid phase fraction-average dendritic crystal solid phase feature diameter curve under a given nucleation density. The method disclosed by the invention is suitable for macrosegregationnumerical simulation in sand casting and metal mold casting of various sizes and complex shapes.

The invention relates to the field of manufacture of large height-diameter ratio circular casting billets, namely circular ingots, for shafts, particularly to a manufacturing tooling and an efficient production method of a large height-diameter ratio circular casting billet, namely a circular ingot. The problems of the quality problems of casting billet shrinkage cavity, porosity and cracks and the low manufacturing efficiency are solved. The manufacturing tooling is provided with a casting system, an ingot mould, a heat insulation feeder head, a heat insulation cover and a slow cooling pit. Before casting, the ingot mould, the casting system and a base plate are assembled in a ground pit and the heat insulation feeder head is preheated. The casting is performed in a slow casting mode. The mould release is performed after the casting in a high-temperature mould release mode and the heat insulation is performed on a steel ingot through the heat insulation cover. After the heat insulation, the steel ingot is hung into the slow cooling pit for slow cooling or directly enters a heat treatment work station through hot delivery to be heated and prepared to be forged. The manufacturing tooling and the efficient production method of the large height-diameter ratio circular casting billet are suitable for the efficient production of the circular casting billet and the high-quality casting billet is provided for the production of the shafts, barrel type forging parts and bar materials, wherein the diameter of the circular casting billet is more than Phi 200 mm and the height-diameter ratio of the circular casting billet is larger than 3.

The invention discloses a cubilose extracting solution as well as a preparation method thereof. The method comprises the following steps: soaking cubilose by water which is 30-100 times of weight of the cubilose, soaking white cubilose and yellow cubilose for 1.5-12 hours and red cubilose for 12-26 hours, thereby obtaining cubilose residue; stewing the residue by water which is 30-100 times of weight of the cubilose; stewing the white cubilose and the yellow cubilose for 3-24 hours and the red cubilose for 15-74 hours, and then extracting the cubilose extracting solution. Compared with generally similar methods, the technological process of the method is greatly simplified; enzymatic hydrolysis is not needed; the production cost is reduced; the product yield is improved. The cubilose extracting solution prepared according to the method contains a lot of cosmetic active ingredients (such as sialic acid) in the cubilose; the concentration of the sialic acid is much higher than that of the cubilose extracting solution prepared by the general preparation method; kinds of obtained cubilose extracting solutions can be processed into kinds of products, so that precious natural supplements of the cubilose are relatively low in material costs and product prices.

The invention relates to the field of the manufacture of a wide thick plate blank for a wide thick plate rolling machine, in particular to a tooling for efficiently manufacturing the wide thick plate blank for the wide thick plate rolling machine and an efficient manufacture method of the wide thick plate blank, aiming at the problems such as cavity shrinking, loosing and cracking and the like of the plate blank and the low manufacture efficiency. The manufacture tooling is provided with a pouring system, an ingot mould, an insulated feeder, a pouring trolley, an automatic control pouring transit line, a heat preservation cover and a burial pit. Before pouring, the ingot mould, the pouring system and a chassis are assembled on the pouring trolley, and the insulated feeder is preheated. The pouring is carried out slowly; after pouring, high-temperature demolding is carried out, and the temperature of a steel ingot is kept by the heat preservation cover; and then the steel ingot is carried away by the trolley, and is hoisted into the burial pit to be slowly cooled. Finally, a flash groove is cut out of the wide thick plate, so that the flashes and strains can be removed, and the wide thick plate is put into a thermal treatment furnace to be annealed. The tooling and the method are applicable to the production of the thick plate blanks with thickness of 350-1200mm and weight of 20-70 tons.

The invention provides ginseng water energizing cream and a preparation method thereof, and also relates to a mask containing the ginseng water energizing cream, as well as application of the ginseng water energizing cream in production of anti-wrinkle preparations. The ginseng water energizing cream comprises ginseng root extract serving as a skin conditioner, a ginseng tissue culture, rosa canina fruit oil, grape seed oil, simmondsia chinensis seed oil, butyrspermum parkii, beta-glucan and ginseng seed oil, as well as a wetting agent, a thickening agent, an emulsifier, a preservative and water.
