Abstract
The invention relates to a spent pulping liquor-type cement grinding aid. The cement grinding aid is prepared from spent pulping liquor discharged from a paper mill as the main raw material by stirring and mixing with an appropriate amount of triethanolamine, sodium lignosulfonate and urea together in an agitation tank. The cement grinding aid has good grinding-enhancing, yield-increasing effects and the like on cement. The distribution of cement particles is also improved, the phenomena of overgrinding and coarse size are avoided, since the spent pulping liquor discharged from the paper mill is used as the main raw material, the environment can be protected and the wastes can be recycled, spent pulping liquor is at no cost, financial subsidies are enjoyed due to the energy conservation and emission reduction, and the preparation method is extremely simple and suitable for being popularized in cement enterprises.
Description
Technical field
The present invention relates to a kind ofly with the grinding aid that reclaims waste and old cardboard and carry out the spent pulping liquor preparation of discharging after recycled paper for paper mill, the admixture that plays grinding aid effect adding during then for the production of cement grinding, relates in particular to and a kind ofly can improve mill output; Save power consumption, cost-saving, increased the grinding aid of strength of cement.
Background technology
In manufacture of cement, grinding is an important process.Conventionally cement clinker is allocated into together with various blended materials and in mill, carried out grinding, and obtain required cement.At present, the most of cement production enterprises of China are all to carry out pulverizing cement with ball mill, and not only energy consumption is large, yield poorly, and while there is ground prod, there will be overground and run thick phenomenon.Make size distribution unreasonable.
At present, domestic while having many enterprises to produce cement, all use grinding aid, but the applicable cases of mixing grinding aid is unsatisfactory.The grinding aid of preparation is mainly to be mixed by trolamine and other grinding aid on the one hand, although there is certain grinding-aid effect, its adding proportion is conventionally higher, the effect that blended material is increased to volume is limited, on the other hand, these grinding aids are mixture, when cement grinding, may there is differing of dispersion in wherein each kind of composition, cause thus the unstable of cement quality, 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, a kind of when can improve strength of cement in the urgent need to obtaining, improve many blending of grinding output condensation material, guarantee 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 the spent pulping liquor formula cement grinding aid that subsidy spent pulping liquor is main material production.
Another object of the present invention is can guarantee that for spent pulping liquor formula cement grinding aid provides a kind of quality product can make preparation method simple to operation again.
Spent pulping liquor formula cement grinding aid of the present invention, the spent pulping liquor that its raw material is mainly discharged by paper mill and trolamine, wooden sodium and urea form, described spent pulping liquor by weight percentage ratio be calculated as 75～80%, trolamine by weight percentage ratio be calculated as 10～6%, wood sodium by weight percentage ratio is calculated as 10～6%, and urea by weight percentage ratio is calculated as raw material that 5～8% ratio sum is 100% and adds in agitated pool and 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 is mixed: get spent pulping liquor by weight percentage ratio be calculated as 75～80% and join in agitated pool, in continuously stirring situation, again successively by trolamine by weight percentage ratio be calculated as 10～6%, wood sodium by weight percentage ratio is calculated as 10～6%, urea by weight percentage ratio is calculated as raw material that 5～8% ratio sum is 100% and joins respectively continuously stirring in agitated pool and mix 30-60 minute, obtains 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, with the grinding aid of the material formulations such as spent pulping liquor, it is a kind of novel concrete grinding aid reinforcing agent, directly separately with 8/1000, mix and produce in cement grinding, to improving cement, there is good grinding aid and reinforced effects, and consumption is few, nontoxic, nothing abrasion, can effectively improve cement quality and output, has further reduced 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 alternative conventional other raw materials such as tap water of grinding aid that spent pulping liquor of the present invention is prepared, compare with conventional trolamine class preparation grinding aid, under equal conditions spent pulping liquor of the present invention can obviously increase cement specific surface area, improves strength of cement and output.
5. because the spent pulping liquor that uses paper mill to discharge is main raw material; can play protection of the environment and the cyclic utilization of waste, spent pulping liquor used not only need not be spent, and also can enjoy because of energy-saving and emission-reduction fiscal subsidy; and preparation method is very easy, be adapted at promoting the use of in cement production enterprise.
Embodiment
