The invention discloses a method for co-producing sodium stannate and stannic oxide by solder removing liquid, comprising the following steps: separating tin in the solder removing liquid, recovering copper, transforming copper into sodium stannate, preparing sodium stannate and preparing stannic oxide. The method of the invention features in low processing cost, simple technical process and device structure, and high product purity and can prepare sodium stannate and stannic oxide.

The invention discloses a manufacturing method of a NO2 gas sensor used for room temperature detection. The manufacturing method of the NO2 gas sensor used for room temperature detection comprises the following steps of: preparing a metal electrode on the surface of a flexible substrate, making a SWCNTs/SnO2 sensitive film, and bonding the SWCNTs/SnO2 sensitive film with the surface of the flexible substrate, provided with the metal electrode, so as to form the NO2 gas sensor used for room temperature detection. By adopting the manufacturing method of the NO2 gas sensor used for room temperature detection, the problems that adhesion between a sensitive material and the flexible substrate is poor and distribution is not uniform are solved, and the aim of causing the sensitive material and the flexible substrate to be firmly bonded and uniformly distributed is achieved.

The invention relates to compound nutritious food with antineoplastic and immunity enhancement functions and a production method for the compound nutritious food with the antineoplastic and immunity enhancement functions, belonging to the field of nutritious food processing. The compound nutritious food is prepared by means of taking soft-shelled turtle, lucid ganoderma, agaricus blazei murill, white fungus, lentinula edodes, hericium erinaceus, maize germ, lemon and red dates as raw materials, and being subjected to ultralow-temperature freezing, crushing, temperature/phase-conversion composite extraction, separation, purification and sterilization. The compound nutritious food has an excellent palatability and special nutrition effects, contains functional components, such as vitamins, mineral substances, edible fungi active polysaccharides and polyunsaturated fatty acids, and has the effects for improving immunity and resisting tumor. The compound nutritious food is especially suitable for recovery of postoperative cancer patients and chemoradiotherapy patients. According to the compound nutritious food with the antineoplastic and immunity enhancement functions and the production method for the compound nutritious food with the antineoplastic and immunity enhancement functions, a soft-shelled turtle full-utilization technology is adopted, edible mushrooms and the maize germ are taken as raw materials, no waste materials are produced in the production process, the utilization rate of the raw materials is high, the compound nutritious food contains no additives, such as essences, pigments, preservatives and stabilizers, toxic and side effects are prevented, and the edible safety is guaranteed.

The invention relates to a method for preparing colored sand and a production system and mainly solves the technical problems of poorer product weatherability, high raw material cost, high high-temperature processing energy consumption, high probability of new environmental pollution and the like of the conventional artificial colored sand. According to the technical scheme, the method for preparing the colored sand comprises steps as follows: firstly, aggregate is added to a container moving circumferentially, then a liquid accounting for 1.3%-1.6% of the weight of the aggregate is added, rolling is performed for 1-2 min, and the aggregate surface is enabled to be wet; colored gelation powder accounting for 6%-8% of the weight of the aggregate is added, rolling wrapping is performed for 3-5 min, the aggregate surface wetted by the liquid is wrapped with the colored gelation powder, and a dense first colored wrapping layer is formed; the steps are repeated; finally, an artificial colored sand raw material is prepared, the thickness of the colored wrapping layer of the artificial colored sand raw material is 10%-55% of average diameter of aggregate particles, the artificial coloredsand raw material is finally put in a curing box with the temperature being 20-60 DEG C and humidity being 60%-90% for 10-15 d, and artificial colored sand is obtained.
