Composite of vegetable insulating oil and modified nano powder and application and preparation method thereof

The invention provides a composite of vegetable insulating oil and modified nano powder and application and preparation method thereof. The composite comprises vegetable insulating oil and nano powder, and the composite is used for preparing insulating oil. The preparation method includes the following steps: surface treatment is carried out on the nano powder; vegetable insulating oil subject towater removal and gas removal is mixed with the nano powder subject to surface treatment; the mixed insulating oil is subject to ultrasonic oscillation; and mixture obtained by oscillation treatment is added into a planet ball mill, and wet grinding is carried out. In the invention, nano powder is added into vegetable insulating oil, nano liquid dielectric medium can be formed, not only the dielectrical property of insulating oil can be improved, but also heat dissipation function of transformer winding coil can be improved; and the nano powder is far smaller than foreign particle in the insulating oil and can form stable sol system with the liquid dielectric medium, and a breakdown bridge can not be formed under the action of external electric field, thus improving the dielectrical strength of insulating oil.

Composite preparation for increasing dissolved oxygen content in pond culture water body

The invention relates to a composite preparation for increasing dissolved oxygen content in a pond culture water body, and belongs to the field of aquatic product culture technology. Cocoamidopropyl Betaine, alkyl glucoside (APG0810), deionized water are weighted in proportion, and are mixed and stirred uniformly at normal temperature for loading into a package barrel. The invention uses two nontoxic pollution-free surfactants with good water-soluble ability and deionized water, and the composite preparation can rapidly reduce surface tension of pond water body, eliminate floating foams on the surface of the water body, thereby oxygen in the atmosphere can enter into the water body continually for rapidly, effectively and continuously increasing content of the dissolved oxygen in the culture water body. The composite preparation has the advantages of convenient usage, small amount, fast-acting and long effect, and can be used in the whole process of the culture period, and does not influenced by weather and environment condition; the composite preparation has an antibiosis function and can effectively establish a good water body ecology base, and builds a good water body environment for cultured biology.

Preparation method and application of rhamnolipid composite surfactant

The invention belongs to the technical field of surfactants, and discloses a preparation method and application of a rhamnolipid composite surfactant. The preparation method comprises the following steps: adding lysozyme into rhamnolipid fermentation liquor which is totally fermented, conducting stirring and reacting under the conditions that a temperature is 45-50 DEG C and a pH value is 5-7, cooling the obtained fermentation liquor to room temperature, then adding APG, carrying out stirring and washing, then adding polyaluminum chloride, carrying out flocculent precipitation and centrifugation, taking a supernatant, and concentrating and drying the supernatant to obtain the rhamnolipid-APG composite surfactant. According to the preparation method disclosed by the invention, lysozyme is used for treating the fermentation liquor, and APG is used for washing, so the yield of rhamnolipid can be remarkably increased; and polymeric aluminum chloride is adopted to carry out flocculent precipitation on the fermentation liquor having been subjected to bacteriolysis treatment, so the purity of the product is improved. The obtained product has good surface activity, and has the advantages of being natural, environment-friendly, non-irritant and biodegradable when being applied to daily chemical washing products.
