Abstract
The invention relates to a high-efficiency cement grinding aid. The high-efficiency cement grinding aid is prepared from the following raw materials in parts by weight: 8 to 14 parts of hydroxyethyl cellulose, 7 to 11 parts of sodium fluosilicate, 4 to 10 parts of sodium chloride, 3 to 10 parts of triethanolamine, 8 to 12 parts of ethylparaben, 7 to 13 parts of fly ash, 4 to 7 parts of polyethylene glycol, 2 to 6 parts of urea, 8 to 14 parts of polycarboxylate, 3.2 to 8.7 parts of anhydrous sodium sulphate, 4.5 to 10 parts of sodium acetate, 3.2 to 4.8 parts of gypsum, 8 to 14 parts of montmorillonite, 4.2 to 8.7 parts of aluminite powder, 2.2 to 4 parts of glass fiber, 6 to 7 parts of magnesium chloride solution, and 2 to 7 parts of perlite. The high-efficiency cement grinding aid has the beneficial effects that the grinding efficiency is improved or the energy consumption is decreased, the influence to quality of cement is avoided, the usage amount is little, and the cost is low.
Description
Technical field
The present invention relates to a kind of efficient cement grinding aid.
Background technology
Cement pulverizing, as the highest process procedure of energy consumption in cement production process, in milling process, often causes cement grinding efficiency to decline, degradation problem under mill efficiency.Cement grinding aid is a kind of chemical addition agent improving cement grinding effect and performance, can significantly improve cement unit-hour output, each age strength of cement, improve its mobility.Cement grinding aid can be greatly lowered in grinding process the Electrostatic Absorption bag ball phenomenon formed, it is possible to reduces the coalescence trend again of the ultra-fine grain formed in grinding process.Cement grinding aid also can significantly improve cement fluidity, improves grinding effect and the grinding efficiency of powder concentrator of grinding machine, thus reduces grinding energy.Present cement grinding aid consumption is excessive, resource causes a kind of waste, adds use cost simultaneously.The efficient cement grinding aid of low amounts, has good market prospect and economic worth.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is to provide a kind of cement grinding aid, improves mill efficiency or reduces energy consumption, and not interfering with cement quality, and usage amount is few simultaneously, low cost.
For solving prior art problem, the technical scheme that the present invention provides is, a kind of efficient cement grinding aid, and it is made up of the raw material of following parts by weight:
Hydroxyethyl cellulose 8-14 part, prodan 7-11 part, sodium chloride 4-10 part, triethanolamine 3-10 part, ethyl hydroxybenzoate 8-12 part, flyash 7-13 part, Polyethylene Glycol 4-7 part, carbamide 2-6 part, polycarboxylate 8-14 part, Matrii Sulfas Exsiccatus 3.2-8.7 part, sodium acetate 4.5-10 part, Gypsum Fibrosum 3.2-4.8 part, montmorillonite 8-14 part, aluminium powder 4.2-8.7 part, glass fibre 2.2-4 part, magnesium chloride solution 6-7 part, perlite 2-7 part.
The invention has the beneficial effects as follows: the cement grinding aid of the present invention, improving mill efficiency or reduce energy consumption, and not interfering with cement quality, usage amount is few simultaneously, low cost.
