The beneficial effects of scientific and rational use of cement grinding aids on cement production: (1) Improve grinding efficiency, increase bench production, and reduce power consumption. This is the most direct effect of using cement grinding aids. Since the grinding aid disperses the particles of the grinding material and increases the fluidity thereof, the grinding medium in the grinding machine strengthens the pulverizing action of the material, thereby improving the grinding efficiency and increasing the production time of the cement. At the same time, the relative power consumption is reduced. (2) The amount of clinker is reduced, and the amount of mixed materials is increased. Since the grinding aid can increase the fine particle content and a part of the grinding aid material itself to promote the hydration of the cement, the cement strength performance can be improved.
A grinding aid is a surfactant that can improve the grinding environment. The common grinding aid is to improve the grinding effect by improving the viscosity of the material in the mill, the dispersion of the particles and the flow state of the slurry. To a large extent, it solves the problems of powder consumption and energy consumption. The main purpose of the grinding aid is to reduce or terminate the aggregation of the particles, to improve the fineness of the cement and the specific surface area, or to grind to the same fineness, and to increase the productivity when adding the grinding aid. At the same time, the addition of the grinding aid adsorbs the surface of the cement particles, reduces the friction between the particles and the adhesion, so that the cement particles slide, and the fluidity thereof also becomes better, thereby improving the grinding efficiency and the cement performance.
Grinding aids are admixtures that are added during cement grinding to aid in the grinding without compromising human health and cement and concrete properties. Alcohol amines are the main components of cement grinding aids in the industry. The strengthening effect of these substances on cement is mainly reflected in two aspects: First, physical reinforcement, that is, the influence of alcohol amines in the grinding process. The change of strength caused by the grading of cement particles, such as the addition of alcohol amines, under the same specific surface area, the concentration of cement particles is concentrated, thereby increasing the strength of the mortar; the second is the chemical strengthening effect, which is the alkalinity of the alcohol amines. The chemical excitation effect of the mineral hydration process.
In the cement industry production, when the clinker grinding to a certain degree of fineness, clinker fine particles will appear agglomeration, paste grinding phenomenon. The agglomeration and pasting of clinker particles lead to a significant reduction in grinding efficiency.
Triisopropanolamine is a chemical used as a solvent in photographic developer for pharmaceutical raw materials. Solvent for paraffin oil in man-made fibre industry. Because the salt formed by triisopropanolamine and long chain fatty acid has good coloring stability.
In chemical enterprises, hazardous chemicals are used in the production process. This is an important type of raw materials and products in the production process, but it is highly valued by chemical companies because of its dangers. At present, the society attaches great importance to safety production events, especially those involving chemical chemicals in chemical enterprises, which will strengthen their internal management. At this stage, China still has many problems in managing hazardous chemicals. In order to achieve safe management of hazardous chemicals in the chemical industry, it is necessary to further explore its management methods.
The substances produced by chemical production are often characterized by flammable, explosive, corrosive and toxic substances, and the production equipment tends to be large. Once an accident occurs, the impact is large, and it is safe for the national economy and the people in the area. Bringing unpredictable losses and disasters. Therefore, the significance of chemical safety is very important, and it is an important part of chemical production management.
How does the strength of cement come into being? Why do cement grinding aid also enhance cement products? With the hydration of cement system, triethanolamine, triisopropanolamine and diethanolisopropanolamine do not change the hydration products of cement. The strength of cement paste increases with the increase of solid precipitation.
