This invention discloses a method for preparing a composite flotation reagent using biomass hydrothermal liquefaction products, comprising the following steps: Raw material preparation: providing biomass raw materials rich in lipids or proteins; Catalytic hydrothermal liquefaction: placing the biomass raw materials and a composite catalyst in a reactor, reacting at a temperature of 250-350℃ and a pressure of 4-20 MPa, wherein the water content of the biomass raw materials is 70-95%, and the composite catalyst contains alkaline components, metal oxide components, and rare earth element components; Product separation: separating the reaction products into oil and water to obtain bio-crude oil containing amphiphilic molecules; Flotation application: applying the bio-crude oil as a composite flotation reagent to mineral flotation, where the bio-crude oil simultaneously functions as a frother and a collector. This invention uses waste biomass as raw material to prepare a composite flotation reagent with both frother and collector functions, realizing the resource utilization of waste and the green upgrading of flotation reagents, and has the characteristics of wide raw material sources, excellent reagent performance, and environmental friendliness.

A foam separation method for harvesting Cr 3+ This method, belonging to the field of heavy metal wastewater treatment, uses the natural nonionic surfactant Sapindus mukorossi extract as a foaming agent and a trapping agent to treat Cr-containing wastewater. 3+ Cr in aqueous solution 3+ Foam separation and harvesting were performed. The critical micelle concentrations of Sapindus mukorossi extract and five other surfactants were determined, and the effects of pH, gas flow rate, liquid loading, collection time, Sapindus mukorossi extract concentration, and Cr were investigated. 3+ The effect of initial concentration on separation efficiency was investigated, and the process was optimized through orthogonal experiments. The results showed that at room temperature, with pH 6.5, gas flow rate 400 mL / min, collection time 4 min, loading volume 300 mL, Sapindus mukorossi extract 0.2 g / L, and chromium sulfate 10 mg / L, Cr... 3+ The recovery rate can reach 71.5%, and the enrichment ratio is 3.9. The foaming agent used in this invention is widely available, easily degradable, and environmentally friendly, and is suitable for low concentrations of Cr. 3+ Separate harvesting.

A kind of gas-liquid mixing device, flushing device and closestool, including being provided with at least sequentially communicating first mixing chamber and second mixing chamber in liquid outlet direction, first mixing chamber is also communicated with first air inlet, and second mixing chamber is communicated with second air inlet and bubble outlet passage;It further includes air inlet channel, air inlet channel is communicated with first air inlet and second air inlet. When using, air enters first mixing chamber and foaming liquid are mixed to constitute preliminary mixed liquid by first air inlet;Preliminary mixed liquid is mixed again with the air entered by second air inlet, to form mixed liquid with numerous micro-bubbles. Compared with viscous foaming liquid, mixed liquid is larger and more delicate in volume, and has better flowability, can quickly form uniform and delicate foam with other liquid, so that less foaming liquid can achieve better foaming effect, keep foam solubility relatively stable, improve the use frequency of single bottle foaming liquid.

The amount of carbon nanotubes (C) relative to 100 parts by mass of polypropylene resin (B) is 3-20 parts by mass, and the amount of polypropylene resin (D) is 6-120 parts by mass. The mass ratio (D) / (C) of the amount of polypropylene resin (D) to the amount of carbon nanotubes (C) is 2-10.

This invention belongs to the field of daily chemical products technology, specifically relating to a pure herbal hair growth and anti-hair loss shampoo based on multi-pathway synergistic effects and its preparation method. The herbal hair growth and anti-hair loss shampoo comprises: hair follicle regulating ingredients, blood circulation promoting ingredients, antibacterial and antipruritic ingredients, and natural surfactant ingredients. This invention scientifically proportions the above ingredients. The extract obtained from the hair follicle regulating ingredients regulates sebum secretion in hair follicles; the extract obtained from the blood circulation promoting ingredients promotes blood circulation in scalp capillaries; the extract obtained from the antibacterial and antipruritic ingredients inhibits scalp infections and hair follicle inflammation; and the surfactants give the shampoo good stability. This invention, through the multi-pathway synergistic effects of the above components, solves the shortcomings of existing herbal shampoo products, such as simple formulas, insufficient extraction of effective ingredients, reliance on chemical surfactants, and limited efficacy. It has the advantages of being natural, gentle, non-irritating, and having a high utilization rate of effective ingredients.
