Abstract
The invention relates to a powder cement grinding aid material, particularly an enhanced powder cement grinding aid. The enhanced powder cement grinding aid is prepared from the following raw materials in parts by weight: 3-6 parts of alcamine compound, 10-20 parts of industrial salt, 30-60 parts of anhydrous sodium sulphate, 5-15 parts of sodium lignosulfonate, 1-5 parts of lime, 1-5 parts of gypsum, 10-25 parts of slag powder and 10-25 parts of fly ash. The grinding aid provided by the invention is compounded from common chemical raw materials and multiple industrial wastes, and has the advantages of accessible raw materials, adequate sources, low toxicity, non-volatility, simple preparation process and low cost. All indexes satisfy the requirements in Standard JC/T667-2004 'Cement Grinding Aid'; the grinding aid not only can enhance the grinding efficiency and yield, but also can obviously the early strength and later strength of cement; and after being mixed in cement, the grinding aid can improve the powder granule distribution and appearance, does not have adverse effect on the cement quality, and has stable performance.
Description
Technical field
The present invention relates to a kind of powdery cement grinding aid material, especially relate to a kind of enhancement type powdery cement grinding aid.Belong to field of cement production.
Background technology
Cement production enterprise is when producing cement, and in cement production process, grinding pow consumption is too high, mill efficiency is low and improve strength of cement and other physicalies in order to solve, and increase mixing material consumption, the problem such as reduces costs, and tends to add cement grinding aid.The grinding aid of selling on current market generally is divided into two kinds of powder grinding aid and liquid grinding aids.Though liquid cement grinding additive has the low characteristics of volume, exist simultaneously to be difficult for storage, complicated operation, measure the drawbacks such as inaccurate, and powdery cement grinding aid can overcome these shortcomings.Nowadays, mostly the powdery cement grinding aid of selling on market is to improve cement grinding efficient as main, and ignores the increase strength of cement, reduces the problems such as cement clinker.Although all meet JC/T667-2004 " cement grinding aid " standard, the problem in solution manufacture of cement that can not be comprehensive can not be the more cost of cement production enterprise saving.
Summary of the invention
The problems referred to above that the present invention exists in order to overcome prior art provide a kind of and can reduce the powder surface free energy, can generally be suitable for again, improve strength of cement, improve a kind of enhancement type powdery cement grinding aid of cement split size distribution and pattern.
The objective of the invention is to be achieved through the following technical solutions:
A kind of enhancement type powdery cement grinding aid, to count ratio by following raw materials in parts by weight to be prepared from: 3～6 parts of alcamine compounds, 10～20 parts of Industrial Salts, 30～60 parts of Sodium sulfate anhydrous.min(99), 5～15 parts of sodium lignosulfonates, 1～5 part of lime, 1～5 part, gypsum, 10～25 parts of slag powders, 10～25 parts, flyash.
Described a kind of enhancement type powdery cement grinding aid, to count ratio by following raw materials in parts by weight to be prepared from: 4～5 parts of alcamine compounds, 13～17 parts of Industrial Salts, 40～55 parts of Sodium sulfate anhydrous.min(99), 8～13 parts of sodium lignosulfonates, 2～4 parts of limes, 2～4 parts, gypsum, 13～22 parts of slag powders, 15～20 parts, flyash.
Described a kind of enhancement type powdery cement grinding aid is to count ratio by following raw materials in parts by weight to be prepared from: 4.5 parts of alcamine compounds, 15 parts of Industrial Salts, 45 parts of Sodium sulfate anhydrous.min(99), 10 parts of sodium lignosulfonates, 2.5 parts of limes, 3 parts, gypsum, 17 parts of slag powders, 18 parts, flyash.
Described alcamine compound is one or both in trolamine or tri-isopropanolamine.
A kind of enhancement type powdery cement grinding aid of the present invention adopts conventional preparation method, presses formulation ratio above-mentioned each raw material is mixed, and stirring namely gets cement grinding aid.
When the present invention used, the volume with 0.3～0.5% added in cement mill, reached the effect of saving power consumption, suitably improving powder efficient utilization and effectively improving quality and the performance of cement, and its volume is preferably 0.45%.
The present invention is the canescence powder, and is easy to use, and cement production enterprise only needs a weighing balance, just can add in grinding machine smoothly after weighing.In the present invention, alcamine compound plays disperse and grind aid, improves cement in early days and the later strength effect, and Industrial Salt and Sodium sulfate anhydrous.min(99) play and improve the cement early strength effect, and sodium lignosulfonate plays auxiliary grinding aid effect.Be applicable to various cement, particularly Portland blastfurnaceslag cement, its volume is the 0.3-0.5% of cement quality.
The present invention compared with prior art has the following advantages effect:
1. grinding aid of the present invention is composited by common industrial chemicals and multiple industrial waste, and raw material is easy to get, and ample supply and prompt delivery, and low toxicity is non-volatile, and the processing preparation is simple, with low cost;
2. indices of the present invention all meets JC/T667-2004 " cement grinding aid " standard-required, accomplishing to improve mill efficiency, improve output simultaneously, can also significantly improve cement early strength and later strength, can improve split size distribution and pattern after mixing cement, cement quality is had no adverse effects, and stable performance.
