Commonly used liquid grinding agent before the main raw material for three isopropanolamine, triethanolamine and now have three can replace triethanolamine and isopropyl alcohol amine new grinding agent of raw materials, Chinese name is two ethanol isopropanolamine, English name Diethanolisopropanol
In cement concrete applications, triisopropanolamine has the following advantages in terms of dispersibility, age enhancement, and application conditions compared with triethanolamine: 1 Dispersibility is better, when used in cement grinding aids, The fundamental principle of the action of the grinding aid is the dispersibility of the two surfactants. The dispersibility of the triisopropanolamine is better due to the spatial stereostructure of the alkyl chain and the hydroxyl group of the triisopropanolamine. Triethanolamine; and dispersibility is an important indicator of cement. In practical applications, triisopropanolamine is superior to triethanolamine in improving the cement, and the fluidity of cement is better than that of triethanolamine.
The water reducing agent is used for concrete mixing, which can change the gas content of the concrete, so that the gap ratio inside the concrete is greatly reduced. The effect of water reducer on the fluidity of concrete is usually reflected by the magnitude of the slump. When the proportion of water and cement used in concrete is constant, the degree of collapse of concrete can be greatly improved by adding a precipitant. And through the use of water reducing agents. The concrete setting time can be extended appropriately. However, it is necessary to properly control the amount of water reducing agent. Maintain reasonableness to avoid excessive increase in concrete that will not condense for a long time. By adding the scientific proportion of the water reducing agent, the performance and strength of the overall concrete structure can be improved, and the proportion of water cement in the concrete is reduced.
Development and application prospects of cement grinding aid products The main market for the application of cement grinding aids, the development and application of new cement grinding aid products need to be strengthened, and its research focus has shifted to polymer synthesis technology. The synthetic polymer grinding aid combines various functional groups into the main chain structure of the polymer, and the smaller grinding aid effect and the compound grinding aid have a leaping improvement. Because the synthetic polymer grinding aid generally has a low effective amount, the grinding aid has obvious effect, and a suitable dosage range, the fluctuation of the dosage has little effect on the performance of the cement, and the production safety can be better ensured. Polymer grinding aids have low cost, good performance and high comprehensive benefits, and have broad application prospects.
