The invention discloses passive millimeter wave imaging security inspection equipment which comprises a one-dimensional focal plane array (1), a reflecting plate (3), a display control sub-system (4), a signal processor (5), an inner calibration combination (6), a reflecting plate rotating mechanism (7), a dielectric panel (8), a rack (9), a detecting table (11), an ellipsoid reflecting surface (2) and an outer calibration combination (10). The ellipsoid reflecting surface (2) focuses electromagnetic waves radiated by a human body, the one-dimensional focal plane array (1) converts the focused electromagnetic waves into voltage signals, the signal processor (5) collects the voltage signals and sends the voltage signals to the display control sub-system (4), and the display control sub-system (4) processes the voltage signals and then outputs two-dimensional grey-scale map. The inner calibration combination (6) and the outer calibration combination (10) are adopted for combined calibration, image quality can be improved, and metal and nonmetal forbidden objects can be detected. The passive millimeter wave imaging security inspection equipment has the advantages of being small in system loss, high in sensitivity and reliability, low in cost, light and the like.

The invention relates provides an environmentally-friendly hand sanitizer and a preparation method thereof. The raw materials for the hand sanitizer comprise alkyl glycoside, coco oil amide propyl lycine, sodium fatty acid methyl ester sulfonate, coconut oil amide propyl amine oxide, glycerol, sodium citrate, lactic acid, hydroxypropyl cellulose, sodium chloride,1,2-benzoisothiazolizone-3-ketone, essence and deionized water. In the hand sanitizer and the preparation method thereof provided by the invention, sodium fatty acid methyl ester sulfonate with good detergency, calcium soap dispersibility, emulsibility, thickening property, hard water resistance, no toxicity and complete biodegradability is adopted, and amphoteric surfactants namely coconut oil amide propyl lycine and coconut oil amide propyl amine oxide with rich foam, mildness and low irritation are matched with alkyl glycoside to generate synergism, thus the hand sanitizer can defecate and clean hands and has the efficacy of mild protection on skin; and glycerol and lactic acid are adopted to improve moisture retention capability of the system, thus skin is not tight after the hand sanitizer is used.

The invention provides a method for regenerating aluminum electrolysis cell carbon-base waste into a raw material for calcium carbide production. The method comprises the following steps that (1) the aluminum electrolysis cell carbon-base waste is broken; (2) the broken aluminum electrolysis cell carbon-base waste is placed into a leaching pond, a stirring leaching device or a rolling mixing leaching device, water is added firstly, then caustic soda or a solution of the caustic soda, quick lime and a drastic oxidation active agent are added, oxidization leaching is conducted, filtering separating is conducted, an aluminum alkali solution and solid filter residues are obtained, and after the solid filter residues are washed with water and dried, activated carbon residues containing carbon and calcium fluoride are obtained; and (3) the activated carbon residues are placed into a rolling mixing machine, a hydrocarbon binder is added, or quick lime is further added, rolling mixing and forming are conducted, and the raw material for calcium carbide production is obtained. According to the method for regenerating the aluminum electrolysis cell carbon-base waste into the raw material for calcium carbide production, the obtained raw material for calcium carbide production is high in carbon content, low in impurity content and high in aluminum and alkali desorption recovering rate; the obtained raw material for calcium carbide production is applied to calcium carbide production, the yield is increased, the average power consumption of calcium carbide of per ton is reduced, the calcium carbide gas yield is increased, and no cyanide is detected; and the method is safe, simple, large in processing quantity and low in energy consumption and cost.

The invention relates to an apple juice and a preparation method thereof. The preparation method comprises the following steps: preprocessing; juicing apples; blending raw apple juice; homogenizing the apple juice, and carrying out vacuum degasification; filling the apple juice, and sealing; and carrying out extra-high-pressure sterilization on the apple juice. The apple juice is the product processed by the preparation method. By carrying out extra-high-pressure sterilization at normal temperature, the invention can effectively reduce enzymatic change and browning caused by thermal reaction in the processing course of the apple juice, solve the problems of mouthfeel and flavor degradation and nutrient loss of the product caused by high-temperature heating sterilization during the traditional thermal sterilization processing, and favorably keep the natural flavor and nutrient of the product.
