Problems solved by technology

The solution to this situation is usually to add cement grinding aids. Most of the commercially available liquid grinding aids are composed of pure chemical substances such as triethanolamine and industrial waste. The cost of grinding aids is very high, and it is easy to Flying dust will worsen the production environment, and the grinding aid effect is not obvious, which will affect the performance of cement

Embodiment 1

[0013] Embodiment 1: The component weight percent of the cement composite grinding aid is 15% of modified triethanolamine, 10% of triethanolamine, 22% of triisopropanolamine, 15% of glycerin, 10% of sodium humate, low molecular weight Fatty salt 1% and clean water 27%.

[0014] After the cement compound grinding aid produced based on this component ratio is added to the material, the strength of the cement is significantly enhanced, the energy consumption is reduced, and the grinding output of the ball mill is increased by more than 15%.

Embodiment 2

[0015] Embodiment 2: The component weight percent of the cement composite grinding aid is 17% of modified triethanolamine, 13% of triethanolamine, 25% of triisopropanolamine, 10% of glycerin, 12% of sodium humate, low molecular weight Fatty salt 1% and clean water 22%.

[0016] After the cement compound grinding aid produced based on this component ratio is added to the material, the strength of the cement is significantly enhanced, the energy consumption is reduced, and the grinding output of the ball mill is increased by 12-15%.

[0017] The cement composite grinding aid of the present invention, its principle is to utilize the performance of its various component raw materials, the adsorption on the surface of solid particles changes the structural properties of the particle surface, reduces the structural properties of the particle surface, reduces the It improves the strength and hardness of the particles, prevents the closure of new cracks, and accelerates the expansion ...

Abstract

The invention provides a cement compound type grinding aid which is high-efficient cement grinding aid integrating grinding and enhancement. The cement compound type grinding aid comprises the following compositions in percentage by weight: 10-20% of modified triethanolamine, 10-15% of triethanolamine, 20-30% of triisopropanolamine, 10-15% of glycerinum, 10-15% of sodium humate, 1% of low-molecular-weight fatty salt and 20-30% of clean water. According to the cement compound type grinding aid, the grinding efficiency of a cement grinding technology and the purification of the working environment in a manufacturing shop can be effectively improved, and the cement compound type grinding aid has the characteristics of lowering the production cost and effectively optimizing the properties of cement.

Description

technical field [0001] The invention relates to building material chemical products, in particular to a cement composite grinding aid, in particular to a high-efficiency cement grinding aid integrating grinding aid and reinforcement. Background technique [0002] Cement is one of the most commonly used building materials and is widely used in civil engineering, hydraulic, national defense and other projects. During the processing of cement, it needs to be ground into powder with a mill. According to the existing cement grinding process, the mill Over-grinding often occurs in the warehouse, resulting in electrostatic adsorption, and the temperature of the clinker entering the mill is extremely high, even reaching 190 degrees. The solution to this situation is usually to add cement grinding aids. Most of the commercially available liquid grinding aids are composed of pure chemical substances such as triethanolamine and industrial waste. The cost of grinding aids is very high a...
