Abstract
The invention relates to the application of polylol glucoside as a cement grinding aid. The polylol glucoside comprises the following components of glucol polyglucoside, diglycol glucoside, propanediol glucoside or glycosylglycerol or is a mixture of the components in arbitrary proportions. The polylol glucoside is used as the cement grinding aid and can greatly increase the efficiency of a cement grinding machine and enhance cement strength at the same time.
Description
Technical field
The present invention relates to cement grinding aid, specifically, is that polylol glucoside is as cement grinding aid.
Background technology
Particle surface all has surface energy.When material was crushed to certain fineness, the particulate surface-area can sharply increase.When for example 1 cubic millimeter solid particulate being broken into the length of side and having only 0.1 millimeter fine particle, its surface-area will increase by 1000 times, and at this moment, its surface energy also will increase by 1000 times.So, when particle is crushed to certain fineness, just need to consume lot of energy.
Cement is the micron-sized powder by cement clinker, gypsum, the common grinding of blended material or the levigate respectively hydraulicity that mixes then.In cement pulverizing course, add an amount of, addition content grinding aid outward at 0.01%-0.1%, can eliminate or weaken the trend that cement granules reassembles.Like this, the energy that is used to pulverize the particle of reuniting with just can be used to pulverize individual particle, makes particle reach thinner state.And the adsorption of grinding aid on the nascent surface that particle is pulverized makes the flowability of cement powder increase again, thereby reduces or prevented the slimeball in the cement grinding mill, stick with paste the mill phenomenon.So, in the grinding process of cement material, add a spot of grinding aid, can significantly improve grinding effect and effective energy consumption that reduces cement grinding.
The organic cpds trolamine is the most frequently used cement grinding aid, and facts have proved it is very effective.In addition, other additives, like terepthaloyl moietie, Diethylene Glycol, 1,2 Ucar 35, glycerine, sulfonated lignin, acetate, oleic acid and dodecylbenzene sulfonate can use as cement grinding aid.
In recent years, along with the rise and the requirement on environmental protection of oil price, the recyclability raw material that comes from biomass is used for cement grinding aid, also causes everybody attention." come from the grinding aid of biomass " and narrated the grinding aid that uses biomass-derived polyvalent alcohol and compositions such as conventional grinding aid raw material such as trolamine to form such as CN101184702A.Again such as; CN101565282A " beet waste mash compound and efficient composite cement grinding aid and working method thereof "; This patents state use a kind of composition of a kind of beet waste mash as cement grinding aid; Not only made full use of trade waste, reduced the cost of cement grinding aid, and can make cement mill output improve 15% to 40%.Have a plurality of hydroxyls on the molecular structure of glucide, also belong to polyol compound, this type of recyclability material can be used as tensio-active agent, is adsorbed on the cement particle surface, can be used as cement grinding aid and uses.But glucide itself is the relatively responsive material of a kind of chemically reactive, and its is prone to redox reaction takes place, easy to change, the decomposition of being heated etc.So, as grinding aid, being prone to deoxidization, degradation with the glucide of recyclability, its product is difficult for prolonged preservation because of corruption, and the various acidic substance that in degradation process, generate, and also can produce the detrimentally affect that can't expect to cement and concrete performance.
Summary of the invention
In cement production process, grinding is an important step.Under general condition, the cement granules size is more little, and aquation is fast more.The cement granules diameter is less than 30 μ m the time, and is active maximum; During greater than 60 μ m, active less, aquation is slow; When greater than 90 μ m, can only carry out surface hydration, only play the effect of micro-aggregate.So, in order to bring into play the gelling property of cement preferably, improve the early strength of cement, just must improve cement fineness.But must be noted that if too much less than the particle of 3 μ m, also can influence other performances of cement, it is very fast to descend like the shelf lives activity of cement, the easy weathering of cement, conglomeration; The need water-based of cement increases, thereby the contraction increase of cement products, frost resistance are reduced or the like.In addition, cement fineness is meticulous to reduce output also with the performance performance of remarkably influenced cement grinding mill, and power consumption increases.So cement pulverizing course not only requires cement products will reach certain fineness, the more important thing is to require product that size-grade distribution is preferably arranged; That is, the cement granules size must have certain distribution, and the cement granules size can not be big or small consistent; But to there be the particle that varies in size to exist simultaneously by a certain percentage; Macrobead bears whole load, and small-particle is dispersed in the slit between the macrobead, only in this way; Just can make cement slurry form fine and close structure, and make the activity of grog and blended material obtain rational and effective performance and raising.Therefore, in the cement grinding production process, rationally control the fineness of cement, the ratio that particularly increases 3-32 μ m grain composition is particularly important, makes the ratio of 3-32 μ m granularity account for 55-65%, to have better cement performance.
Polylol glucoside is as the application of cement grinding aid.
Above-mentioned polylol glucoside can be terepthaloyl moietie glucoside, glycol ether glucoside, Ucar 35 glucoside or glycosylglycerol, or the mixture of their arbitrary proportion.
Above-mentioned polylol glucoside is as the application of cement grinding aid, and the consumption of polylol glucoside is the 0.03-0.05% of cement quality.
When above-mentioned polylol glucoside is used as cement grinding aid, can add the terepthaloyl moietie that mass percentage concentration is 0-50%, the Diethylene Glycol of 0-50%, the Ucar 35 of 0-50%, the USP Kosher of 0-50%, the trolamine of 0-50% or the composite use of tri-isopropanolamine of 0-50%.
Above-mentioned polylol glucoside and terepthaloyl moietie, Diethylene Glycol, Ucar 35, USP Kosher, trolamine or tri-isopropanolamine are composite when using as cement grinding aid, and the total consumption of cement grinding aid is the 0.015-0.05% of cement quality.
The present invention with polylol glucoside as the grinding aid raw material; It had both possessed the advantage of polyalcohols grinding aid; Improve the efficient of cement mill, overcome glucide again and be prone to the putrid limitation of degraded, special in grinding process to improving the content of 3-32 μ m cement granules; Act on especially obviously, 3-32 μ m granule content is accounted for about 55-65%.
Polylol glucoside is as grinding aid, and its grinding-aid effect is obvious, and it not only can use separately but also can compositely use.
