How much do you know about TIPA triisopropanolamine?
Whether it's parking lots for cars equipped with Chevrolet sensors and cell phone holder for car horizontal, or open workstation equipped with anti-rodent cables, convenient sauna rooms, or swimming pools equipped with pool thermometers, all of these constructions can’t live without the cement. And triisopropanolamine can play an important role on increasing the output of cement.
What is TIPA triisopropanolamine?
Triisopropanolamine is also known as TIPA. Isopropanolamine began industrial production in the 1980s, and its production and consumption are mainly concentrated in Germany, the United States, the United Kingdom and other countries. Due to the unique physical and chemical properties of isopropanolamine, it is widely used in developed countries. Isopropanolamine belongs to the class of alkanolamines, which is an alcoholamine compound with an amine group and an alcoholic hydroxyl group. According to the composition of the hydroxyl group, it is divided into three homologous products: monoisopropanolamine, diisopropanolamine and triisopropanolamine. Because its molecule contains both amino and hydroxyl, it has the comprehensive properties of amine and alcohol, has a wide range of industrial uses, and is an important basic chemical raw material. This article mainly introduces the application of triisopropanolamine in grinding aids.
Advantages of triisopropanolamine
In the application of cement and cement concrete, compared with triethanolamine, triisopropanolamine has the following advantages:
👉The dispersion is better. Triisopropanolamine and triethanolamine are both used in cement grinding aids. The basic principle of their grinding aids is their dispersibility as surfactants. The dispersibility of triisopropanolamine is better than triethanolamine because of its alkane chain and hydroxyl isomerized steric structure. Dispersibility is an important indicator of cement. In practical applications, triisopropanolamine can increase the production of cement better than triethanolamine, and it is also better than triethanolamine in improving the fluidity of cement.
👉Early enhancement performance. Both triisopropanolamine and triethanolamine are early strength agents, but triethanolamine changes the early setting characteristics of cement to achieve early strength effects; and triisopropanolamine achieves early strength effects by promoting early setting characteristics . Specifically, triethanolamine promotes the early hydration of aluminate, delays the hydration of silicate, improves the early strength, but shortens the setting time; triisopropanolamine promotes the water of ferrite, which is more difficult to hydrate. The hydration and dispersibility can improve the hydration degree of cement minerals, thereby improving the early strength.
👉Late enhancement performance. Triethanolamine mainly promotes the early strength of cement, and triisopropanolamine greatly improves the late strength of cement by promoting the hydration of more difficult to hydrate minerals and improving the dispersibility of cement. Foreign tests have shown that triisopropanolamine can increase the late strength of cement by more than 3 MPa, even 5-12 MPa.
👉The application performance is stable. The application of triethanolamine has obvious restrictions on its dosage. When the dosage exceeds 0.1%, flashing will occur, which will affect the setting characteristics of cement; and the dosage range of triisopropanolamine is 0.001% to 2. As its content increases, the strengthening effect of cement will gradually increase. At present, under the dual effects of rising oil prices and increased demand for ethylene products by enterprises, the price of ethanolamine continues to rise, and the price gap between isopropanolamine and ethanolamine has greatly narrowed, and ethanolamine has gradually lost its price advantage. As countries around the world pay more and more attention to environmental issues, the application of ethanolamine is gradually being restricted. For example, the "Pollutant Release and Transfer Register" of developed countries lists ethanolamine as a hazardous substance and restricts its use, thus accelerating the replacement of ethanolamine. .
Application of triisopropanolamine in grinding aid
In the field of cement grinding aids, the early alcohol amine compounds used as grinding aids were mainly triethanolamine. Because the dispersibility and late strength of triisopropanolamine are better than triethanolamine, with the development of the cement industry and the intensification of competition, the application of triisopropanolamine in cement grinding aids has been developed rapidly.
The application of triisopropanolamine in cement grinding aids is manifested in that the cement grinding aids contain triisopropanolamine, triethanolamine, additives and water. The auxiliary agent mentioned here is one or more of carboxylic acid, lignosulfonate, and alkylsulfonate. According to the requirements of the formula, add a certain proportion of water to triisopropanolamine, then add other raw materials and stir in the kettle under normal temperature and pressure until all the indicators of the product are qualified, and then the material is discharged.
There are two methods of adding:
👉One is to add triisopropanolamine directly during cement grinding. When the temperature is low (<10℃), the 85% triisopropanolamine is difficult to transport due to its high viscosity, so it should be diluted with water to 65%-70% before adding it and transported with a pump. The optimal addition amount is about one ten thousandth of the total raw materials.
👉The second is the direct addition of triisopropanolamine in concrete production. Triisopropanolamine and high-efficiency water-reducing agent are used in combination, the content of which is about 0.1% of cement, and the content of high-efficiency water-reducing agent is about 0.8% of cement (main excitation strength). As the content of triisopropanolamine increases, the strength will gradually increase, but due to the increase in its dispersibility, the amount of air entrained will increase, which hinders the increase in strength. When the air-entraining amount exceeds 3%, the strength begins to decrease with the increase of air-entraining amount. At this time, a certain amount of block polymer can be added (about 1/10 of triisopropanolamine, preferably epoxy compound).
