Abstract
The present invention discloses a granular neutral cement grinding aid which is composed of 40 to 50% of anhydrous sodium sulfate, 10 to 20% of dihydrate gypsum, 25 to 45% of zeolite calx, and 1 to 5% of triethanolamine. The present invention also proposes a preparation technology for the cement grinding aid. The present invention can activate effective components in cement raw materials so as to enhance the strength of the cement. The present invention can save the cement clinker and reduce the polluted gas exhaust so that the present invention belongs to the green product. The chamber sticking phenomenon can be avoided in the process of use because of the granular or agglomerate shape of the present invention. The present invention enhances the cement machine-hour yield, reduces the production cost, and has simple and easy manufacture method, and consequently, the product with stable quality and easy use can be obtained.
Description
Technical field
The present invention relates to a kind of particulate state cement grinding aid, and corresponding preparation technology.
Background technology
In the process of making cement, after grog, additional materials and the gypsum mixtures of cement add grinding machine, in the process of grinding, because violent, frequent, complicated friction and bump between storeroom, material and the grinding element, make material produce static, the material that has electric charge can be adsorbed on the surface of steel ball and grinding element, causes cement mill serious bag ball, bag forging phenomenon to occur; Be higher than at 5% o'clock in the additional materials humidity that adds, can in grinding machine, produce a large amount of water vapour again, the humidity of abrasive is increased, can produce above-mentioned bag ball, bag forging phenomenon equally, cement output and quality are descended significantly.
Produce electrostatic problem for solving cement mill at process of lapping, have the external electricity of employing to eliminate static, effect is not so good; The employing cement grinding aid is also arranged, but existing grinding aid kind single, cost an arm and a leg the quality instability.
Summary of the invention
Technical problem to be solved by this invention is to avoid above-mentioned deficiency of the prior art, thereby and proposes the particulate state neutral water cement grinding aids that a kind of effect of improving cement effective constituent is saved grog, and corresponding preparation technology.
Technical scheme provided by the present invention is: a kind of particulate state neutral water cement grinding aids, and this grinding aid is made up of anhydrous sodium sulphate, dihydrate gypsum, zeolite calx, trolamine, and its weight proportion is respectively:
Trolamine 1～5% anhydrous sodium sulphate 40～50%
Dihydrate gypsum 10～20% zeolite calxs 25～45%
Further, the weight proportion of each composition is respectively:
Trolamine 5% anhydrous sodium sulphate 45%
Dihydrate gypsum 20% zeolite calx 30%
Also propose a kind of preparation technology of above-mentioned cement grinding aid in addition, this preparation technology may further comprise the steps: zeolite calx and dihydrate gypsum are crushed to 100～200 purpose powder, heat anhydrous sodium sulphate to 60～80 ℃ simultaneously, join in the powder then and stir; In the whipping process, evenly add trolamine, after stirring mixture is made granularly or block, oven dry obtains finished product.
Further, described powder diameter is 150 orders.
Further, described anhydrous sodium sulphate is heated to 80 ℃.
The present invention has following advantage: can activate the effective constituent in the cement raw material, thus the intensity of refinforced cement; Can save cement clinker, the gas that reduces pollution emissions belongs to green product; Particulate state or block profile have been avoided sticking storehouse phenomenon in the product use; Improve the unit-hour output of cement, reduce production costs; Making method is simple, obtains steady quality, product easy to use.
Embodiment
Describe the present invention in detail below in conjunction with specific embodiment.
Embodiment one:
Particulate state neutral water cement grinding aids, this grinding aid is made up of anhydrous sodium sulphate, dihydrate gypsum, zeolite calx, trolamine, and the weight of each component is respectively: anhydrous sodium sulphate 323.4Kg, dihydrate gypsum 115.5Kg, zeolite calx 308Kg, trolamine 23.1Kg.
Embodiment two:
Particulate state neutral water cement grinding aids, this grinding aid is made up of the component of Different Weight: anhydrous sodium sulphate 98.1Kg, dihydrate gypsum 43.6Kg, zeolite calx 65.4Kg, trolamine 10.9Kg.
Embodiment three:
Particulate state neutral water cement grinding aids, this grinding aid is made up of the component of Different Weight: anhydrous sodium sulphate 523.6Kg, dihydrate gypsum 214.2Kg, zeolite calx 440.3Kg, trolamine 11.9Kg.
The manufacture craft of the product of the foregoing description is: zeolite calx and dihydrate gypsum are crushed to 150 purpose powder, heat anhydrous sodium sulphate to 80 ℃ simultaneously, join in the powder then and stir; In the whipping process, evenly add trolamine, after stirring mixture is made granularly or block, wherein granulated product can be made into thin discs: high 8～10mm, bottom surface diameter are 6～8mm, and granular or bulk product oven dry are obtained white little Huang Cheng's product.
Particulate state neutral water cement grinding aids can solve sticking storehouse problem in the existing cement making processes, and cement grinding aid commonly used is Powdered, causes sticking storehouse easily, causes material proportion inaccurate, does not reach and evenly goes into to grind the result, makes cement quality defective.
Particulate state neutral water cement grinding aids can activate the effective constituent in the cement raw material, in cement pulverizing course, 0.5～0.7% the particulate state neutral water cement grinding aids that evenly adds cement raw material, can effectively save grog 12～18%, and strength of cement strengthened intensity enhancing 10～15% after 20～30%, 28 days in 3 days; Saving grog just can avoid to air discharging SO
2Gas reduces and pollutes.This grinding aid can improve 2 tons/hour of cement outputs in addition, saves 10～15 yuan/ton of the electricity charge, brings abundant profit can for numerous cement production enterprises.
