The invention relates to freshening and whitening toothpaste and a preparation method thereof. The freshening and whitening toothpaste comprises the following raw materials: hydrated silica, disodium dihydrogen pyrophosphate, a PVM / MA copolymer, color repair particles and an auxiliary agent, the color repair particles are prepared from mannitol, microcrystalline cellulose, CI 74160, cetyl alcohol, corn starch, ethyl cellulose and hydroxypropyl methyl cellulose. Through combination of triple whitening methods, tooth whitening is realized, a color locking film is formed on the surface of the whitened tooth, color spots and color spots are prevented, and the tooth yellowing risk is reduced. Experiments prove that the freshening and whitening toothpaste disclosed by the invention has an effect of freshening breath, the temperature of the inner wall of the oral cavity can be remarkably reduced by 4.5 DEG C by using the toothpaste, and the toothpaste has no irritation to the mucous membrane of the oral cavity and is high in safety.

The invention belongs to the field of crude sand of quartz sand for casting, and particularly relates to composite quartz sand which is low in cost, low in energy consumption, low in linear thermal expansion rate and high in refractoriness and a preparation method of the composite quartz sand. The preparation method of the composite quartz sand comprises the following steps: 1) uniformly mixing quartz sand, bauxite, zircon powder, olivine powder, chromite powder, calcium carbonate, magnesium oxide, silicon phosphate and dextrin in a bowl-shaped sand mixer; (2) adding one or more adhesives such as phosphate, water glass, hydrated silicon dioxide and dextrin, and uniformly mixing; and 3) roasting the mixed material at the temperature of less than or equal to 400 DEG C to obtain the composite quartz sand.

The invention belongs to the technical field of oral care, and particularly discloses whitening toothpaste and a preparation method thereof. The whitening toothpaste comprises the following components in percentage by mass: a transparent matrix component, a whitening active component and an auxiliary component. The transparent matrix comprises hydrated silica, sorbitol, cellulose gum and xanthan gum; the whitening active component comprises an optical modifier, an active decolorizing agent and an endogenous inhibitor. Through the synergistic effect of the optical modification component and the bioactive component, exogenous stain decomposition and endogenous pigment inhibition are realized while the high light transmittance of the cream is maintained, the use of peroxide bleaching agents is avoided, and the whitening cream has the advantages of being good in whitening effect, transparent and stable in cream body, small in damage to enamel, safe and comfortable to use and the like.

The application discloses a treatment method of carbonation hydrated silica production wastewater. The method comprises the following steps: 1) adding calcium-magnesium carbonate as a desiliconizing agent in the carbonation hydrated silica production wastewater; 2) heating and wet decomposing sodium bicarbonate in the carbonation hydrated silica production wastewater, cooling the solution through heat exchange, then performing settlement and filtration to obtain a precipitate and a desiliconized filtrate; the precipitate contains a large amount of calcium-magnesium carbonate, which is returned to step 1) for desiliconization; carbon dioxide generated in the wet decomposition process is returned to a production system to participate in the synthesis of hydrated silica as an acid source; 3) after the desiliconized filtrate is precisely filtered, the desiliconized filtrate is concentrated through a membrane to obtain concentrated salt-containing wastewater and concentrated effluent, and the concentrated effluent is returned to a production line to be used as process water; 4) the concentrated salt-containing wastewater is transferred to an evaporation crystallization system to be concentrated and crystallized, to obtain sodium carbonate monohydrate crystals and condensed water, the condensed water is reused as production water, and the sodium carbonate monohydrate is sent to a drying system; 5) the sodium carbonate monohydrate sent to the drying system is calcined at high temperature to obtain sodium carbonate products, which are sent to a water glass production workshop through pipeline transportation and used as raw materials. The application solves the bottleneck of scaling in the treatment process of the carbonation hydrated silica production wastewater in the prior art, and solves the problems of high operation cost and large equipment investment of the wastewater treatment.

The invention relates to whitening and freckle-removing toothpaste and a preparation method thereof. The whitening and freckle-removing toothpaste comprises tetrasodium pyrophosphate, sodium fluoride, sodium phytate, hydrated silica, synthetic fluorophlogopite and carbomer. The tetrasodium pyrophosphate, the sodium fluoride, the sodium phytate, the hydrated silica, the synthetic fluorophlogopite and the carbomer are combined, so that a synergistic effect is achieved, the effects of whitening, removing stains and removing exogenous stains can be achieved, and the tooth whitening degree is improved from the inside and the outside.

The oral care composition comprises hydrated silica, disodium dihydrogen pyrophosphate, calcium silicate, hydroxyapatite, zinc citrate and sodium monofluorophosphate. According to the invention, a plurality of active substances are reasonably compounded, and the substances play a role from multiple dimensions, so that the excellent effects of whitening and protecting enamel are achieved.

The invention provides a composition with oil control and cleaning effects and application thereof. The composition with the oil control and cleaning effects comprises collagen, Himalaya powder salt, walnut shell powder and hydrated silica. The collagen comprises any one or a combination of at least two of a recombinant human source III type collagen, a recombinant human source IV type collagen or a recombinant human source XVII type collagen. The invention creatively finds that the collagen, the Himalaya powder salt, the walnut shell powder and the hydrated silica are matched and have a synergistic effect, so that the effects of adsorbing redundant grease on the skin surface, regulating the skin feeling, removing old and waste cutin, dredging pores and removing grease dirt on the surface layer and pores can be better realized.

The invention discloses a method for producing white carbon black by a carbonization method, which comprises the following steps of: diluting industrial water glass serving as a raw material with deionized water until the concentration of the water glass is 5-15wt%, adding 4-6wt% of sodium bicarbonate serving as an electrolyte and 0.005-0.01 wt% of sodium dodecyl benzene sulfonate serving as a dispersing agent into a reaction solution, performing carbonization reaction at the temperature of 50-80 DEG C, and determining a reaction endpoint according to a pH value. The carbonization reaction is carried out in three serially connected bubble towers with the same size and structure, the first bubble tower is a main carbonization tower, and the second bubble tower and the third bubble tower are carbonization-washing towers. According to the present invention, with the method, the problems of difficult washing and low white carbon black surface area caused by gel dissociation, agglomeration and wrapping during the white carbon black production by using the traditional carbonization method are solved, and the detection results show that the white carbon black has the good stability and the good stability; the white carbon black produced by the method disclosed by the invention stably meets the A-class standard requirements in HG / T-3061-2020 rubber compounding agent hydrated silicon dioxide.
