Abstract:
The utility model relates to the technical field of guar gum crushing device, and discloses a guar gum crushing device for producing guar gum hydroxypropyl trimethyl ammonium chloride, comprising a crushing bin, the inner walls of the left and right sides of the crushing bin are fixedly connected with guide plates, and the left side of the crushing bin is fixedly connected with a feed bin. The guar crushing device for the production of guar hydroxypropyl trimethyl ammonium chloride, by placing the material to be crushed in the feed hopper, and then starting the left drive motor to rotate the left propeller, the material entering the feed bin from the feed hopper is transported upward, and then enters the crushing bin through the feed hole to realize the feeding of the material. The whole feeding process reduces the degree of the staff to overcome the gravity work, thus, the labor intensity of the staff is reduced. After the material enters the crushing bin, the two back driving motors can be started at the same time, so that the two crushing rollers are rotated, so that the material is crushed.

jaguarc13s - Study on the preparation of cationic carboxymethyl hydroxypropyl guar gum and its retention and drainage properties
from Baidu Library

Abstract:
1-allyl-3-methylimidazolium acetate ([AMIM]Ac) as reaction medium, 3-chloro-2-hydroxypropyltrimethylammonium chloride (CTA), sodium chloroacetate, the cationic carboxymethyl hydroxypropyl guar gum (CCMHPG) was prepared by a novel one-step method using propylene oxide as modifier. The effects of the amount of three modifiers, the amount of alkali, reaction temperature and reaction time on the degree of substitution and viscosity of the product were studied, and the optimum preparation conditions were determined. The cationic substitution degree of the reaction product was 0.24, The carboxymethyl substitution degree was 0.41, the hydroxypropyl substitution degree was 0.36, the water solubility of the product was good, and the viscosity of 1% aqueous solution was 1 072 mPa · s. The infrared spectra and ~ 1H NMR spectra of CCMHPG showed that quaternary ammonium groups, carboxymethyl groups and hydroxypropyl groups were successfully grafted onto guar gum molecules. The electron microscope images showed that the particle surface had wrinkles and flaky cracks. The CCMHPG/PAC binary particle system was used for deinked waste paper pulp. When the addition amount of PAC was 0.8%, and the addition amount of CCMHPG was 0.04%, the retention rate was 94.3%, and the freeness was 43 ° SR.
