2results about How to "Reduce surface residue" patented technology

The application discloses a preparation and use method of a NbTi superconducting wire low-temperature inlay welding flux, and relates to the technical field of superconducting wires, and comprises the following steps: heating deionized water to 50-60 DEG C; respectively water-bath heating short-chain alkyl glycoside and polyethylene glycol in the water at 50-60 DEG C for 30-60 seconds; stirring the obtained hot deionized water under the condition of 100-150 r / min, and adding the obtained short-chain alkyl glycoside and polyethylene glycol; and adding xanthan gum and sodium benzoate into the obtained solution in sequence to obtain the flux. The application uses short-chain alkyl glycoside as the main component of the flux; the addition of a thickening agent realizes the physical covering of the copper material surface and prevents the secondary oxidation of the copper material, so that the completely environment-friendly flux meeting the enterprise sewage discharge standard is suitable for the low-temperature inlay welding WIC conventional product with the largest base number, and the obtained WIC product has very low surface residue.

This utility model relates to the field of hygiene product technology, specifically to an adult diaper absorbent core that improves absorption speed. It includes an upper absorbent core layer, a middle absorbent core layer, and a lower absorbent core layer. The upper and lower absorbent core layers are fixedly connected to the upper and lower sides of the middle absorbent core layer, respectively. High-speed absorption grooves are provided at both the front and rear ends of the top of the upper absorbent core layer. A crotch ventilation groove is provided at the top of the upper absorbent core layer, located between the two sets of high-speed absorption grooves. A bottom layer is fixedly connected to the bottom of the lower absorbent core layer. The upper, middle, and lower absorbent core layers are all made of a mixture of wood pulp fiber and multiple sets of polymer particles. The upper and middle absorbent core layers each have a high-absorption zone and a low-absorption zone inside. This utility model, through a gender-differentiated zoned absorption design, significantly improves wearing comfort and reduces product costs while ensuring superior absorbency.
