Example Embodiment

[0146] Example 1: Using the product GSPO-01M of the present invention to produce reed bleached chemical pulp

[0147] A large pulp and paper company in Northwest my country uses reed as a raw material to produce high-quality bleached chemical pulp. The company uses a sulfite pulping process. It is known that the liquid ratio controlled by this enterprise is 1.0:8.0, the PH value is 3.0~4.0; the operating pressure controlled by the cooking process is 6.0Kgf / cm 2 , The time is 6.0 hours, the production process is: feeding, cooking, pulping, washing, concentration, refined pulp, 1, 2, 3 stage bleaching to the papermaking system.

[0148] The average degree of polymerization of cellulose molecules in the fibers of virgin reed pulp is about 5600-5800, which is a medium fiber papermaking plant material. In addition to inorganic raw materials, the cooking aids used by the company usually include naphthalene sulfonates, lignosulfonates, biological enzymes and thiourea dioxide. The requirem...

[0158] Example 2: Using the GSPO-01M of the invention to produce larch bleached chemical pulp

[0159] A forest pulp and paper enterprise in Northeast my country uses larch as raw material and uses alkaline pulping technology to produce bleached chemical pulp. The bleaching process is hypochlorite three-stage bleaching. It is known that the liquid ratio controlled by the production process of this enterprise is 1.0:8.5, the pH value is 12.5~13.0, and the operating pressure controlled by the cooking process is 5.0~6.0Kgf / cm 2 , The time is 6.0-7.0 hours, the production process is: material preparation, cooking, pulping, concentration, refined pulp, three-stage bleaching, and sending to the papermaking system.

[0160] According to experimental analysis, the number average degree of polymerization of cellulose molecules in the cellulose of native larch is about 5500-5700, which is a medium fiber papermaking plant fiber raw material. In addition to NaOH, the cooking aids used by this ...

Abstract

The invention provides a quick-acting dissolving osmotic active matter, and a preparation method and application thereof. The quick-acting dissolving osmotic active matter comprises compound unsaturated fatty acid ethyl ester soap liquid and compound unsaturated fatty acid polyoxyethylene (9) ether phosphate potassium salt, wherein composite unsaturated fatty acids in the compound unsaturated fatty acid ethyl ester soap liquid and the compound unsaturated fatty acid polyoxyethylene (9) ether phosphate potassium salt are respectively and independently selected from at least one of C12-C18 unsaturated fatty acids. A composition of the quick-acting dissolved osmotic active matter has high permeability, compatibility, antistatic property and saponification value, and can effectively reduce oravoid the use amount of chemical raw materials and cooking aids in the paper pulp preparation or waste paper treatment process.

Description

technical field [0001] The invention relates to the technical field of organic synthesis and pulping and papermaking, in particular to a quick-acting dissolving osmotic active substance and its preparation method and application. Background technique [0002] In the pulp and paper industry, people usually use natural plant fiber raw materials to produce pulp. Pulp includes chemical pulp, chemical mechanical pulp and mechanical pulp. Whether the oxygen-alkali pulping or the sulfite pulping is used, NaOH, H 2 o 2 、Na 2 CO 3 、Na 2 SiO 3 、Na 2 SO 3 , NaClO, sodium naphthalene sulfonate, sodium lignosulfonate, thiourea, biological enzymes and other chemical raw materials or cooking aids. In the process of processing waste paper with high processing difficulty such as chemical fibers and mixed fibers containing various polymer functional materials, it is necessary to use excessive NaOH, 27.5%H 2 o 2 (NaClO), Na 3 PO 4 and beating enzymes and other raw materials and add...
