Abstract
The invention discloses an efficient cement liquid grinding aid. The efficient cement liquid grinding aid is characterized by being prepared by the following processes: burdening running water, sodium sulfate, anhydrous sodium acetate, triethanolamine, ethylene glycol, sulphonated melamine resin, molasses and calcium formate to prepare a liquid grinding aid, and preparing the liquid grinding aid according to the weight ratio in the process of preparing the liquid grinding aid, wherein the liquid grinding aid is added according to 0.3-0.5% of weight of cement in the technical process of grinding cement by the liquid grinding aid. When the efficient cement liquid grinding aid is added to a cement grinding process to be used, the grinding efficiency is improved, the production energy consumption and the production cost are reduced, meanwhile, the strength performance of the cement is improved, and mixing of an admixture can be improved when the dosage of a clinker is reduced under the condition that the cement strength is kept not to be changed, and thus, the production cost is saved.
Description
Technical field
The present invention relates to technology of producing cement field, relate in particular to efficient cement liquid grinding aid.
Background technology
Existing cement liquid grinding aid, mill efficiency is not high, in the time of pulverizing cement, need add more liquid grinding aid, improves grinding cost, the cement quality that impact is produced simultaneously.
Summary of the invention
The object of this invention is to provide one and can improve cement grinding efficiency, reduce grinding cost and the efficient cement liquid grinding aid that improves cement performance simultaneously.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of efficient cement liquid grinding aid, its feature is: select tap water 48%-55% according to weight percent, sodium sulfate 2%-4%, sodium acetate, anhydrous 3%-4%, trolamine 7%-9%, ethylene glycol 4%-6%, sulfonated melamine resin 12%-17%, molasses 8%-10%, calcium formiate 4%-7% prepares burden and manufactures liquid grinding aid, manufacture liquid grinding aid process and first add tap water according to above-mentioned weight proportion, then add sodium sulfate, after sodium acetate, anhydrous stirs and dissolves for 10-30 minute, add again trolamine, ethylene glycol, sulfonated melamine resin, molasses, calcium formiate stirs 10-30 minute, make liquid grinding aid, in use liquid grinding aid pulverizing cement technological process, add liquid grinding aid according to the 0.3%-0.5% of cement weight.
Advantage of the present invention is: the present invention, in the time adding cement grinding process use to, improves mill efficiency, has reduced production energy consumption and production cost, has improved the strength property of cement simultaneously; In the situation that keeping strength of cement constant, when can reducing grog usage quantity, improve mixing of blended material, and then save production cost.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described:
A kind of efficient cement liquid grinding aid, select tap water 50% according to weight percent, sodium sulfate 3%, sodium acetate, anhydrous 4%, trolamine 8%, ethylene glycol 5%, sulfonated melamine resin 15%, molasses 9%, calcium formiate 6% is prepared burden and is manufactured liquid grinding aid, manufacture liquid grinding aid process and in agitated pool, first add tap water according to above-mentioned weight proportion, then add sodium sulfate, after sodium acetate, anhydrous stirs and dissolves for 20 minutes, add again trolamine, ethylene glycol, sulfonated melamine resin, molasses, calcium formiate stirs 20 minutes, make liquid grinding aid, in use liquid grinding aid pulverizing cement technological process, add liquid grinding aid according to 0.4% of finished ground cement raw material weight, cement is carried out to cement grinding mill.
A kind of efficient cement liquid grinding aid, select tap water 53% according to weight percent, sodium sulfate 2%, sodium acetate, anhydrous 3.5%, trolamine 8.5%, ethylene glycol 5.5%, sulfonated melamine resin 15%, molasses 7.5%, calcium formiate 5% is prepared burden and is manufactured liquid grinding aid, manufacture liquid grinding aid process and in agitated pool, first add tap water according to above-mentioned weight proportion, then add sodium sulfate, after sodium acetate, anhydrous stirs and dissolves for 25 minutes, add again trolamine, ethylene glycol, sulfonated melamine resin, molasses, calcium formiate stirs 25 minutes, make liquid grinding aid, in use liquid grinding aid pulverizing cement technological process, add liquid grinding aid according to 0.45% of finished ground cement raw material weight, cement is carried out to cement grinding mill.
Beneficial effect of the present invention: the present invention, in the time adding cement grinding process use to, improves mill efficiency, has reduced production energy consumption and production cost, has improved the strength property of cement simultaneously; In the situation that keeping strength of cement constant, when can reducing grog usage quantity, improve mixing of blended material, and then save production cost.
Embodiment recited above is described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; do not departing under the prerequisite of design concept of the present invention; various modification and improvement that in this area, common engineering technical personnel make technical scheme of the present invention, all should fall into protection scope of the present invention.
