The invention belongs to the technical field of sanitary products, and in particular relates to a decontamination moisturizing baby wet tissue and a preparation method thereof. The wet tissue provided by the present invention includes a solution and a carrier, the solution uses water as the solute, and includes the following components in percentage by weight: 0.01%-0.05% of savantine, 1%-6% of cocoyl sodium glutamate, ethylene glycol Disodium amine tetraacetate 0.1‑0.3%, glycerin 3‑10%, preservative 1‑7%, acid 0.01‑0.2%, alkali 0.005‑0.1%, oat extract 0.01‑0.05%. The three substances added to the wet wipes, savantine, sodium cocoyl glutamate, and disodium ethylenediaminetetraacetate, act synergistically to achieve antibacterial, decontamination, and water retention capabilities, and can quickly remove milk on baby clothes. Stains, saliva stains, urine stains, etc.

The invention provides a collecting agent for collecting minerals of oxidized ores such as ilmenite and a preparation method thereof, and belongs to the technical field of mineral flotation collectingagents. The mineral flotation collecting agent for the oxidized ores such as ilmenite is used after ammonium dibutyl dithiophosphate, ethylenediaminetetraacetic acid salt, maleate, sodium oleate andthe like are mixed; and the mineral flotation collecting agent has the characteristics of good water solubility, good dispersion and high selective adsorption ability to objective minerals, and is mainly used for flotation separation of valuable minerals in the oxidized ores such as the ilmenite, scheelite and wolframite. The preparation method of the mineral flotation collecting agent for the oxidized ores is simple in process, operation is easy to control, the prepared collecting agent has the advantages of high selectivity, good dispersion, low agent dosage and high mineral separation comprehensive efficiency, and quite important significance for promoting mineral separation of the minerals such as the oxidized ores is achieved.

The invention discloses a cyanide-free silver-based composite plating solution, a silver-based composite plating layer and a preparation method of the silver-based composite plating layer. The cyanide-free silver-based composite plating solution comprises silver nitrate, a multicomponent complexing agent, conductive salt, a buffering agent, a cationic surfactant, an additive and micro-nano particles; the multielement complexing agent takes triethylenetetramine or / and soluble salt thereof as a main complexing agent, and takes one or more of triethylenetetramine hexaacetic acid or triethylenetetramine hexaacetic acid salt, ethylenediaminetetraacetic acid or ethylenediaminetetraacetic acid salt, and citric acid or citrate as an auxiliary complexing agent; the concentration of the silver nitrate is 0.1-0.7 mol / L, the concentration ratio of the main complexing agent to the silver nitrate is 1-6:1, the concentration of the auxiliary complexing agent is 0.05-1 mol / L, the concentration of theconductive salt is 0.2-1.2 mol / L, the concentration of the cationic surfactant is 0.0005-0.003 mol / L, and the buffering agent is used for the pH value of the cyanide-free silver-based composite plating solution to be 1-7. The cyanide-free silver-based composite plating solution is stable, and the prepared silver-based composite plating layer has the functions of friction reduction and wear resistance and has good compactness.
