4results about How to "Reduce particle size" patented technology

This invention belongs to the field of display materials technology, and relates to a low-reflectivity black dispersion and its preparation method. The low-reflectivity black dispersion comprises the following components in parts by weight: 15-20 parts organic black pigment, 1-5 parts blue pigment, 1-5 parts red pigment, 0.1-2 parts red derivative, 0.1-2 parts black derivative, 3-6 parts dispersant, 3-6 parts acrylic resin, and 54-78 parts solvent. This invention uses organic black pigment to replace carbon black as the black matrix, adds blue and red pigments to reduce the reflectivity of the organic black photoresist composition film, and adds red and black derivatives to improve dispersion stability and reduce the viscosity and particle size of the dispersion. The low-reflectivity black dispersion of this invention has small particle size and stable dispersion, reducing the reflectivity after film formation while maintaining blackness.

According to the operation head of the waste cutting machine, it is guaranteed that the transverse push rod can adapt to the diversity of the thickness and shape of tree trunks to bend the tree trunks, the transverse posture of the transverse push rod is adjusted in the process that the trees are gradually toppled, the transverse push rod is pushed to follow and press the tree trunks, the reaction in the tree trunk toppling process is resisted, and the roller cutter head keeps the stable transverse posture; it is guaranteed that the roller cutter head accurately exerts force on the tree, position deviation and invalid cutting during cutting are reduced, the cutting efficiency is improved, the cutting adaptability of the operation head is improved, the forward toppling angle of the cut tree is controlled, tree toppling is accelerated, and the cutting efficiency is improved. The disassembly and assembly assembly is used for achieving rapid butt joint with or disengagement from the machine frame, the maintenance convenience and efficiency of the operation head are improved, the secondary cutting plate is installed in the machine frame, secondary crushing of chippings is achieved, the chipping uniformity is improved, accumulation of the chippings in the machine frame is reduced, the running resistance of the roller cutter head is reduced, the roller is prevented from being stuck, energy is saved, and the fault rate of the operation head is reduced.

This invention provides a high-satiety chicken small molecule peptide and its application in chicken meal replacement powder. First, a gastric self-expanding microsphere is prepared, with yeast β-glucan and hydroxypropyl methylcellulose as the wall material and modified chicken small molecule peptide as the core material. The microsphere absorbs water and expands in the acidic environment of the stomach, generating a feeling of fullness. In the intestinal environment, it slowly releases the modified chicken small molecule peptide, promoting absorption and regulating intestinal health. Furthermore, solid-state fermentation of mixed grain powder using Aspergillus oryzae is used to prepare the chicken meal replacement powder. The addition of the gastric self-expanding microsphere and fermented mixed grain powder further enhances satiety, meeting the market demand for healthy meal replacement foods.

The application discloses a preparation process and system of an ultralow-temperature heat-conducting basalt fiber yarn, and the preparation process comprises the following steps: after coating particles enter a target area, the coating particles float; the target area forms a floating area; the basalt fiber yarn moves through the floating area, and the coating particles in the floating area are adhered to the basalt fiber yarn; and after drying, a heat preservation layer is formed on the surface of the basalt fiber yarn. The application can form a heat preservation layer on the surface of the moving basalt fiber yarn, and a high-voltage electric field does not need to be formed between the basalt fiber yarn and the coating particles in the coating process, thereby avoiding a safety hidden danger caused by a continuously changing electric field caused by the continuously moving basalt fiber yarn, and improving the safety of the preparation process.
