2results about How to "Reduce adsorption loss" patented technology

This invention discloses a method and apparatus for sorting nickel powder for silver-nickel paste, relating to the field of electronic material preparation technology. The invention involves pretreatment via atmosphere replacement, followed by deagglomeration under an alternating magnetic field, corona charging, grading and screening, and closed-loop gas circulation to complete the sorting process. Each stage is equipped with a precise detection module to collect data in real time, while the main control module dynamically adjusts parameters. During grading, a voltage of the same polarity is applied to form an electrostatic shielding layer, and the purified gas is recycled and reused. The apparatus includes a chamber, a Venturi device, an alternating magnetic field dispersion chamber, a grading chamber, a fan, and various detection modules, exhibiting an integrated structure and strong interconnectivity. This invention achieves precise control and integrated operation throughout the entire sorting process, effectively improving the uniformity and purity of nickel powder particle size, reducing energy consumption and material loss, avoiding nickel powder oxidation contamination, and meeting the stringent requirements of silver-nickel paste for raw materials. Its practicality and economic efficiency are significant.

This invention belongs to the field of cosmetic raw material preparation technology, specifically relating to a method for decolorizing Xinjiang erythromycin, its products, and applications. The method includes: raw material pretreatment: pulverizing Xinjiang erythromycin and processing it using high-pressure instantaneous explosion technology; extraction: extracting the pretreated material with an ethanol-water solution, and obtaining a crude extract of Xinjiang erythromycin after solid-liquid separation; activated carbon decolorization: adding ethanol to the crude extract and mixing evenly, then adding activated carbon for decolorization treatment, followed by solid-liquid separation after decolorization; resin purification: loading the supernatant obtained after decolorization onto a resin column, performing gradient elution, collecting the ethanol eluent rich in phenolic acids, concentrating, and drying. This invention achieves an excellent balance between efficient decolorization and retention of highly active ingredients. It can strongly adsorb and remove dark pigments while significantly reducing the adsorption loss of the target phenolic acids.
