Peeling type waterborne cleaning agent for optical glass

The invention discloses a peeling type waterborne cleaning agent for optical glass. The peeling type waterborne cleaning agent is prepared from the following raw materials in percentage by weight: 3 percent to 8 percent of isomeric alcohol polyoxyethylene ether, 2 percent to 5 percent of fatty alcohol polyoxyethylene polyoxypropylene ether, 1 percent to 3 percent of isomeric alcohol polyoxyethylene ether phosphate, 1 percent to 3 percent of fatty acid methyl ester polyoxyethylene ether sodium sulfonate, 0.5 percent to 2 percent of polyethylidene polyqudinedrnium, 0.2 percent to 1 percent of a fluorocarbon type surfactant, 5 percent to 10 percent of a washing assistant, 2 percent to 5 percent of a metal chelating agent and the balance of water. The peeling type waterborne cleaning agent for the optical glass, disclosed by the invention, has extremely low surface tension and prominent capabilities in the aspects of wetting effect and permeability; the peeling type waterborne cleaning agent has an extremely low emulsifying capability and basically does not emulsify oil dirt; a peeling type oil dirt washing manner is adopted and the consumption of useful-effect components in the cleaning agent is effectively reduced, so that the service life of the cleaning agent is greatly prolonged and the sewage treatment cost is greatly reduced; the popularization and application of the waterborne cleaning agent are facilitated; meanwhile, the peeling type waterborne cleaning agent does not contain water body polluting components including phosphorus, APE (Alkylphenol Ethoxylates) and the like, so that the peeling type waterborne cleaning agent has environment-friendly components and is easy to degrade.

Preparation method for regular-hexagonal-prism-shaped magnesium-doped zinc oxide film

InactiveCN105481263AHigh purityWith large area uniformityIce waterNew energy
The invention discloses a preparation method for a regular-hexagonal-prism-shaped magnesium-doped zinc oxide film. The microstructure of the magnesium-doped zinc oxide film is in the shape of a regular hexagonal prism, and possesses the advantages that the crystallization degree is high and surface defects are less. The preparation method of the film comprises separately dissolving zinc acetate, magnesium acetate, triethanolamine and ammonia water in a mixture of glycol and ice water, getting proper amount of the solution and a cleaned substrate, transferring into a teflon inner container of a hydrothermal kettle for hydrothermal reaction, after the reaction is finished, performing washing, drying and annealing processing on the substrate, so as to prepare a layer of the regular-hexagonal-prism-shaped magnesium-doped zinc oxide film on the substrate. The preparation method is simple in technology, good in repeatability, low in cost, strong in controllability, low in synthesis temperature, green and friendly to environment. The obtained product is in the shape of a regular hexagonal prism, is good in crystallinity, high in purity, less in surface defects, uniform in morphology distribution and consistent in orientation, and possesses potential application prospect and scientific research value in the fields of photoelectric materials new energy.
