Abstract
Spent pulping liquor formula cement grinding aid of the present invention, the spent pulping liquor using paper mill to discharge is main raw material, is uniformly mixed forms with appropriate trolamine, wooden sodium and urea in agitated pool.To cement, there is the good effect such as grinding aid enhancing, volume increase.Further improve being evenly distributed of cement granules simultaneously; do not produce overground; run thick phenomenon; because the spent pulping liquor using paper mill to discharge is main raw material; can serve protection of the environment and the cyclic utilization of waste, spent pulping liquor used not only need not be spent, and also can enjoy fiscal subsidy because of energy-saving and emission-reduction; and preparation method is very easy, be adapted at promoting the use of in cement production enterprise.
Description
Technical field
The present invention relates to the grinding aid that the spent pulping liquor preparation of discharging after waste and old cardboard carries out recycled paper is reclaimed in a kind of paper mill, then for the production of the admixture playing grind-aiding effect added during cement grinding, particularly relating to one can improve mill output; Save power consumption, cost-saving, add the grinding aid of strength of cement.
Background technology
In manufacture of cement, grinding is an important process.Usually cement clinker is allocated in mill together with various blended material and carry out grinding, and the cement needed for obtaining.At present, the most of cement production enterprise of China is all use ball mill to carry out pulverizing cement, and not only energy consumption is large, yields poorly, and when there is ground prod, there will be overground and run thick phenomenon.Make size distribution unreasonable.
At present, domestic have many enterprises produce cement time, all use grinding aid, but the applicable cases of mixing grinding aid is unsatisfactory.The grinding aid of preparation is mainly mixed by trolamine and other grinding aid on the one hand, although there is certain grinding-aid effect, its adding proportion is usually higher, blended material is increased to the limited use of volume, on the other hand, these grinding aids are mixture, differing of dispersion may be there is in wherein each kind of composition when cement grinding, cause the instability of cement quality thus, make cement early anaphase intensity improve not obvious simultaneously, make later strength poor, and trolamine price comparison is expensive, causes use cost too high.
Therefore, in the urgent need to obtain a kind of can improve strength of cement while, improve grinding output many blending condensation material, ensure the stable performance of cement, and effectively reduce the cement grinding aid of manufacture of cement cost.
Summary of the invention
For the weak point of above existing cement grinding aid, the object of the present invention is to provide a kind of cheapness even to enjoy and subsidize the spent pulping liquor formula cement grinding aid that spent pulping liquor is main material production.
Another object of the present invention is can guarantee that quality product can make preparation method simple to operation again for spent pulping liquor formula cement grinding aid provides a kind of.
Spent pulping liquor formula cement grinding aid of the present invention, the spent pulping liquor that its raw material is discharged primarily of paper mill and trolamine, wooden sodium and urea form, it is 75 ~ 80% that described spent pulping liquor percentage is calculated, trolamine percentage is calculated is 10 ~ 6%, it is 10 ~ 6% that wood sodium percentage is calculated, urea percentage calculate be 5 ~ 8% ratio sum be 100% raw material add in agitated pool to be uniformly mixed and form.
The preparation method of spent pulping liquor formula cement grinding aid of the present invention, mainly comprises the following steps:
A) get the raw materials ready: get agitated pool ready, spent pulping liquor. trolamine, wooden sodium, and urea;
B) batching mixing: getting that spent pulping liquor percentage calculates is 75 ~ 80% join in agitated pool, in continuously stirring situation, trolamine percentage being calculated successively is 10 ~ 6% again, it is 10 ~ 6% that wood sodium percentage is calculated, urea percentage calculate be 5 ~ 8% ratio sum be 100% raw material to join in agitated pool continuously stirring mixing 30-60 minute respectively, obtain required cement grinding aid.
Spent pulping liquor formula cement grinding aid of the present invention, obviously has following effect and feature:
1. with spent pulping liquor 75 ~ 80% and subsidiary material trolamine 10 ~ 6%, wooden sodium 10 ~ 6%, urea 5 ~ 8%, mixing and stirring to 30 ~ 60 minute in stirring at normal temperature pond, without any need for the effect of reacting by heating process, method is simple, cost is extremely low, and productive rate is high, easy to implement.
2. test-results shows, a kind of novel concrete grinding aid reinforcing agent with the grinding aid of the material formulations such as spent pulping liquor, directly separately with 8/1000, mix and produce in cement grinding, to raising cement, there is good grinding aid and reinforced effects, and consumption is few, nontoxic, nothing abrasion, can effectively improve cement quality and output, reduce further manufacture of cement cost.
3. the pH value of spent pulping liquor of the present invention is 6 ~ 7%, can mix arbitrarily with other raw material.
4. the composition in other raw material such as the alternative conventional tap water of grinding aid of spent pulping liquor of the present invention preparation, compared with preparing grinding aid with conventional trolamine class, under equal conditions spent pulping liquor of the present invention obviously can increase cement specific surface area, improves strength of cement and output.
5. the spent pulping liquor owing to using paper mill to discharge is main raw material; can serve protection of the environment and the cyclic utilization of waste, spent pulping liquor used not only need not be spent, and also can enjoy fiscal subsidy because of energy-saving and emission-reduction; and preparation method is very easy, be adapted at promoting the use of in cement production enterprise.
Embodiment
Spent pulping liquor formula cement grinding aid of the present invention, the spent pulping liquor that its raw material is discharged primarily of paper mill and trolamine, wooden sodium and urea form, it is 75% that described spent pulping liquor percentage is calculated, trolamine percentage is calculated is 10%, it is 10% that wood sodium percentage is calculated, urea percentage calculate be 5% ratio sum be 100% raw material add in agitated pool and be uniformly mixed;
Or described spent pulping liquor percentage to calculate be 78%, trolamine percentage is calculated is 8%, it is 8% that wooden sodium percentage is calculated, urea percentage calculate be 6% ratio sum be 100% raw material add in agitated pool and be uniformly mixed;
Or described spent pulping liquor percentage to calculate be 80%, trolamine percentage is calculated is 6%, it is 6% that wooden sodium percentage is calculated, urea percentage calculate be 8% ratio sum be 100% raw material add in agitated pool and be uniformly mixed;
