The invention belongs to the technical field of high polymer materials, and particularly relates to a high-strength papermaking forming net fiber. Comprising the following raw materials in parts by weight: 75-90 parts of polyethylene glycol terephthalate, 5-15 parts of polybutylene terephthalate, 3-10 parts of a modified fiber filler, 2-5 parts of modified graphene, 2-8 parts of silicon dioxide, 0.5-2 parts of a silane coupling agent KH-560, 1-3 parts of an anti-hydrolysis agent, 0.5-1.5 parts of an antioxidant and 0.3-1 part of a lubricant. Wherein the modified fiber filler is prepared by sequentially carrying out modification processes such as silane coupling agent, citric acid-glycerol esterification, iron bismuth oxide loading and the like on glass fibers; the modified graphene is prepared by introducing dopamine, cerium ions and glycidyl methacrylate for modification. The mechanical strength, the hydrolysis resistance and the wear resistance of the fiber are remarkably improved through the synergistic effect of all the components and the melt spinning-multi-stage stretching process, and the fiber is particularly suitable for a forming net of a high-speed paper machine.

The invention relates to the field of cosmetics, particularly emulsions, and their uses in the cosmetic care and cleansing of keratinous materials, preferably hair, and skin, preferably the scalp, and more particularly to compositions such as cosmetic compositions in the form of shampoo, conditioner, mask, hair serum, scalp protective serum, or hair and / or scalp scrub. The present invention relates to a cosmetic composition, in the form of an oil-in-water emulsion, comprising: 5 to 25% oil phase by mass relative to the total mass of the composition, and 75 to 95% aqueous phase by mass relative to the total mass of the composition, characterized in that the aqueous phase comprises dehydroxanthan gum, and the oil phase comprises cetyl alcohol and glyceryl stearate citrate. No figure is shown in the abstract.

This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for the production of glyceryl citrate stearate. It includes a fixed ring, inside which the reaction vessel body is fixedly installed. A protective cover is fixedly installed on the top of the reaction vessel body, and a stirring structure is provided on the top of the protective cover. Simultaneous driving of two electric push rods on both sides causes the telescopic rods to move the mounting plate downwards, thereby causing two second inclined plates to move downwards. Since the inclined edges of the two second inclined plates are in contact with the inclined edges of the first inclined plate, the downward movement of the second inclined plates causes the first inclined plate to extend its telescopic rod from the side rod, thereby causing the polytetrafluoroethylene scrapers on both sides to expand outwards and contact the inner wall of the reaction vessel body. At this point, the servo motor is restarted, causing the rotating rod to drive the polytetrafluoroethylene scrapers to rotate, thus scraping off the deposits on the inner wall of the reaction vessel body. Afterwards, the vessel can be rinsed with clean water, thus achieving the purpose of scraping off deposits on the inner wall after the reaction.

The invention relates to the technical field of animal feed fermentation, in particular to a fermentation preparation in a feed production process and a preparation technology of the fermentation preparation. The fermentation preparation is composed of microcapsules, the microcapsules comprise a core material layer and a coating wall material layer, the core material layer comprises lactobacillus plantarum, candida utilis, betaine and peptone, the coating wall material layer comprises an inner layer and an outer layer, the inner layer is a (trehalose-6-phosphoric acid)-beeswax compound, and the outer layer is a (trehalose-6-phosphoric acid)-beeswax compound. And the outer layer is a monoglyceride citrate-Arabic gum compound. After entering a feed production environment, the fermentation preparation is subjected to three-stage change: firstly, an outer layer glyceride citrate-Arabic gum compound is dissolved at proper temperature and humidity to form a network channel; secondly, a transition area is formed between the inner layer and the outer layer through intermolecular interaction, and permeation is adjusted; finally, the inner layer (trehalose-6-phosphoric acid)-beewax compound forms an electrostatic network, so that the protective release of active substances is realized, and the fermentation quality is improved.

The invention discloses a synthesis method of glyceryl citrate stearate, which comprises the following steps: S1, in a nitrogen atmosphere, carrying out esterification reaction on glycerol and fatty acid to generate a monoglyceride mixture, and purifying the monoglyceride mixture to obtain monoglyceride; s2, adding monoglyceride into a solvent, and heating for dissolving; s3, after heating and dissolving, adding citric acid and a catalyst into the solvent, and heating to a reaction temperature; and step S4, after reacting for a period of time, controlling the reaction system at a relatively low vacuum degree, slowly evaporating the acetic acid out of the reaction system, and thoroughly evaporating the acetic acid out of the reaction system before the reaction is finished, so as to obtain the citric acid glycerol fatty acid ester. The method is high in yield, simple, low in cost and easy for large-scale preparation.
