2results about How to "Fully evenly distributed" patented technology

This utility model relates to the field of mining blasting technology and provides a dust suppression device after open-pit mine blasting. The device includes a main body with a water tank fixedly installed inside. A water injection pipe is fixedly embedded in the right side of the water tank, and the outer surface of the water injection pipe is fixedly embedded in the rear side of the main body. It also includes a feeding component fixedly embedded inside the main body. In use, the design of the feeding tray and stirring blade structure allows for precise control of the dust suppressant dosage each time, while effectively mixing the dust suppressant and water to ensure a fully uniform distribution. This enhances the adhesion of the sprayed water mist particles, enabling them to adhere more effectively to the surface of fine dust particles, increasing the settling velocity of the dust particles. This improves the settling velocity of fine particles and reduces the likelihood of them being blown away by the wind.

The invention discloses a preparation method of cross-linked cellulose fibers, and belongs to the technical field of cellulose preparation. The method comprises the following steps that a cross-linking agent solution and a catalyst solution are added to Lyocell fibers, preliminary curing is conducted under the first set temperature condition, the preliminarily cured Lyocell fibers are obtained, in the cross-linking agent solution, the mass percentage content of a cross-linking agent solute ranges from 0.1% to 10%, and the mass percentage content is defined as a; in the catalyst solution, the value range of the mass percentage content of a catalyst solute is (0-5%) * a; under the condition of a second set temperature, washing the cured Lyocell fiber, changing the electron cloud density distribution of the cured Lyocell fiber, and completing deep curing to obtain the deeply cured Lyocell fiber; and carrying out post-treatment on the deeply cured Lyocell fiber, so as to obtain the cross-linked cellulose fiber. The cross-linking limiting device can improve the uniformity of cross-linking limiting and the product quality.
