Abstract
The invention relates to an improved cement grinding aid. The improved cement grinding aid is characterized by comprising components in parts by weight as follows: 15-25 parts of triethanolamine, 2-8 parts of polytetrafluoroethene, 3-6 parts of propylene glycol, 2-5 parts of xanthan gum, 5-10 parts of sodium nitrite, 3-8 parts of calcium lignosulfonate, 5-10 parts of sodium acetate, 5-10 parts of a water-retention material, 5-10 parts of a papermaking black liquid, 6-12 parts of industrial salt and 5-10 parts of molasses. With the adoption of the improved cement grinding aid, the grinding efficiency of a cement mill can be remarkably improved by 8%-15%, the early strength of cement can be properly increased by 2-3 MPa, and the late strength of the cement can be increased by 2-4 MPa, and the formula of the improved cement grinding aid contains no harmful ingredient and meet the requirement of environment protection; the components cooperate with one another, and the adaptability of the grinding aid is improved, so that the grinding aid is applicable to cement at different grades, the use range is widened, the grinding aiding effect is greatly improved, the machine-hour yield is also increased, the energy consumption is reduced, and the mixing amount is little and accounts for 0.02-0.05% in per ton of cement.
Description
Technical field
The present invention relates to a kind of enhanced cement grinding aid.
Background technology
Cement grinding is necessary operation in manufacture of cement and key link, its energy consumption and power consumption account for 30% and total power consumption more than 70% of manufacture of cement total energy consumption, current, country's low-carbon environment-friendly require more and more higher, cement price is dispirited, starting material and energy prices appreciate, industry competition is white-hot, and the benefit of cement production enterprise is had too many difficulties to cope with.So energy-saving and emission-reduction, development low-carbon economy, reduces costs, and improving grinding aid performance, is the problem that cement industry urgently will solve.For reducing energy consumption, improve mill efficiency, people take the measure of following two aspects usually: one, improve milling equipment and grinding process to utilize mechanical energy to greatest extent; Two, in cement pulverizing course, add cement grinding aid to improve mill efficiency.Wherein the second measure is the research emphasis of current field of cement production.America and Europe, the developed countries such as Japan, the use of grinding aid is quite general, and we are also in the infancy.In use still there is a lot of problem, as villaumite brings very large potential safety hazard to cement and concrete weather resistance in the existing grinding aid of China; Grinding aid quality is unstable, and volume is large, thus causes cement quality fluctuation etc.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of enhanced cement grinding aid.
Described a kind of enhanced cement grinding aid, is characterized in that being made up of the component of following weight part: trolamine 15-25, tetrafluoroethylene 2-8, propylene glycol 3-6, xanthan gum 2-5, Sodium Nitrite 5-10, wooden calcium 3-8, sodium-acetate 5-10, water-keeping material 5-10, black liquid 5-10, Industrial Salt 6-12, molasses 5-10.
Described a kind of enhanced cement grinding aid, is characterized in that being made up of the component of following weight part: trolamine 18-22, tetrafluoroethylene 4-6, propylene glycol 4-5, xanthan gum 3-4, Sodium Nitrite 6-9, wooden calcium 4-7, sodium-acetate 6-8, water-keeping material 6-8, black liquid 6-8, Industrial Salt 8-10, molasses 6-8.
Described a kind of enhanced cement grinding aid, is characterized in that being made up of the component of following weight part: trolamine 20, tetrafluoroethylene 5, propylene glycol 4.5, xanthan gum 3.5, Sodium Nitrite 8, wooden calcium 6, sodium-acetate 7, water-keeping material 7, black liquid 7, Industrial Salt 9, molasses 7.
Combination formula of the present invention uses the present invention to have the effect of the later strength improving cement further, the mill grinding efficiency 8%-15% of cement can be improved significantly, the effect of suitable raising cement early strength 2-3MPa and increase cement later strength 2-4MPa, and this combination formula containing any objectionable constituent, does not meet environmental requirement; Each component is worked in coordination with mutually, improves the adaptability of grinding aid, and to be applicable to the cement of different grades, increase use range, grinding-aid effect improves greatly, also improves unit-hour output, reduce energy consumption, and volume is low, is 0.02-0.06%/ton cement.
