Abstract
The invention relates to a mcromolecular grinding aid, which is particularly suitable to be used in the processing and preparation in the cement industry. The grinding aid is prepared from the component of triethanolamine, sugar ether, mirabilite and dodecylbenzene in a weight ratio of 100-220:80-130:50-100:30-80. The grinding aid has a powerful dispersion function and large capability of adjusting the viscosity of ore pulp and resisting calcium ions and magnesium ions and suffers few influences of the pH value. The grinding aid reduces the particle size of the ore pulp and promotes the dispersion of the particles, thereby improving the flowability of the ore pulp and reducing the strength and hardness of the particles. Meanwhile, the grinding aid prevents newly generated cracks from closing and promotes the expansion of cracks.
Description
Technical field
The present invention relates to a kind of grinding aid, relate in particular to a kind of Mcromolecular grinding aid, be particularly useful for the processing of cement industry.
Background technology
In the material crushing process, material is subjected to the effect of different sorts stress usually, causes material to form crackle and expansion, is pulverized then.According to lattice Lifei law, the required minimum stress of brittle rupture is directly proportional with the specific surface energy of material.Obviously, reduce the particulate surface energy, can reduce the stress that makes its fracture required.From the process of particle fracture, the grinding aid molecule can reduce the stress of crack propagation in fresh surface absorption.From the process of particle fracture, the grinding aid molecule can reduce the required external stress of crack propagation in the absorption of fresh surface, promotes the expansion of crackle.So on this point, the chemical substance that can reduce solid surface energy can reduce particulate intensity, thereby can improve crush efficiency or reduce the pulverizing energy consumption.Lie Binjieer has at first studied the influence that liquid ruptures to solid materials under organic and two kinds of situations of inorganic chemistry additive.He thinks, liquid (especially water) will influence crackedly to a great extent, add tensio-active agent and can enlarge this influence.Reason is that table can reduce behind the solid surface adsorption surface active agent molecule, causes linkage force to weaken.
Except above-mentioned particulate intensity and hardness, consider that from disintegrating process the principal element that influences mill efficiency and energy consumption also has effect between ore pulp massfraction, viscosity and material dispersed state, material and grinding medium and the lining board of grinder or the like.These factors all influence the flowability of material in the grinding machine.Therefore, the flowability of improving material in the grinding machine to a certain extent can improve crush efficiency.People such as Crane Pa Er think that by a large amount of research grinding aid has improved the flowable of dry powder or slip, have obviously improved the material speed by grinding machine continuously, thereby have influenced material disintegrating process process; In addition, Liu Dongxing improvement also influences the distribution of particle in grinding machine and the grinding of grinding medium; The existence of grinding aid is by mutual reunion or bonding between the dispersiveness prevention particle good between its maintenance particle.In this sense, grinding aid is the material that can reduce ore pulp viscosity and improve the ore pulp flowability.
But the dissemination of grinding aid of the prior art is relatively poor relatively, regulates the viscosity of ore pulp and anticalcium ion, the magnesium ion ability is less relatively, existed by problems such as the influence of pH value is bigger.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, design through optimization of C, make meticulously, a kind of Mcromolecular grinding aid is provided, it is relatively poor relatively to have solved in the prior art grinding aid dissemination, regulates the viscosity of ore pulp and anticalcium ion, the magnesium ion ability is less relatively, is subjected to problems such as the influence of pH value is bigger, and cost is lower, is suitable for promoting.
Technical scheme of the present invention is as follows:
It is formulated by weight by following compositions, tri-isopropanolamine: sugar ether: mirabilite: dodecylbenzene=100-220: 80-130: 50-100: 30-80.
The preferred weight ratio of raw material of the present invention is tri-isopropanolamine: sugar ether: mirabilite: dodecylbenzene=170: 105: 82: 63.
Advantage of the present invention and beneficial effect are as follows:
The dissemination of grinding aid of the present invention is stronger relatively, regulates the viscosity of ore pulp and anticalcium ion, the magnesium ion ability is relatively large, is subjected to the influence of pH value less.And grinding aid of the present invention reduces the granularity of ore pulp, promotes particulate to disperse, thereby improves the flowable of ore pulp, reduces particulate intensity and hardness, stops the closure of newborn crackle simultaneously, promotes the expansion of crackle.
