The method comprises the following steps: mixing alkali liquor and cotton linters subjected to impurity removal, and performing continuous boiling, washing, pulping, degritting, primary concentration, chlorine alkalization, bleaching, acid treatment, water washing, degritting, secondary concentration and papermaking, so as to obtain the cotton pulp. The mass ratio of alkali in the alkali liquor to the absolute-dry cotton linters is (13 to 15): 100; the temperature for continuous boiling is 108 to 115 DEG C; the period for continuous boiling is 55 to 65min. According to the method, cotton pulp is prepared through a high alkali content, low temperature and short time continuous coiling mode, materials are uniformly heated in a tube, uniform permeation of alkali liquor is achieved, and the product polymerization degree is uniform; cotton fiber primary walls and secondary walls can be destroyed furthest, so that the degree of crystallinity of cotton pulp fiber is reduced, the amorphous region rises, and the reaction activity of the cotton pulp is improved. Through the adoption of the cotton pulp with high reaction activity, high-quality carboxymethylcellulose can be prepared.

The invention belongs to the technical field of steelmaking, and specifically relates to a method for detitanium removal of molten iron in a converter: before tapping in an iron plant, adding a detitanium agent to the molten iron in a blast furnace tapping trough; Add detitanium agent into the iron ladle; remove the detitanium slag before desulfurization at KR desulfurization station; In terms of mass percentage, the mass ratio of the detitanium agent to the molten iron in the blast furnace tapping trough is (1.5-1.8) kg: (0.9-1.0) t; The addition rate of the titanium removal agent is 60-260kg / min; the mass ratio of the titanium removal agent to the molten iron in the ladle is (2-8)kg:(0.9-1.0)t. The method of the present invention optimizes and controls a series of titanium removal agents, titanium removal slag removal, converter blowing, etc., so as to obtain steel with low titanium content and various corresponding products thereof, and the average titanium content is controlled at 0.0005-0.0006%.
