Triisopropanolamine is an amine separated from rectification after addition reaction of ammonia and propylene oxide. It can be widely used in daily chemical industry, fine chemical industry, petrochemical industry, etc. It is an important amine compound. TIPA is the core raw material of cement grind

Concrete is an important material used in engineering construction, and has many advantages such as low price and energy saving. But concrete is not a material with perfect technical performance, and the problem of shrinkage cracks is a problem that has not been solved for a long time. There are man

In petroleum extraction, due to the hydration expansion, dispersion, and migration of clay minerals in petroleum reservoirs, permeability decreases, water injection pressure increases, and oil recovery decreases. At present, in the actual production of oil fields, the method of adding clay stabilize

Triisopropanolamine is an anhydrous white solid, mainly used in the synthesis of intermediates, as a chain extender on PU and as a neutralizer / emulsifier on daily chemicals. Triisopropanolamine is mainly used in cement admixtures. One is to improve ball milling efficiency and reduce energy consump

Cement grinding aid is a small product in the cement industry chain, but it plays a very important role in increasing production and reducing consumption in the cement industry, and can bring real benefits to cement enterprises. So what is a liquid cement grinding aid? What is the role of liquid cem

The main raw materials of cement grinding aids studied and used at home and abroad are divided into inorganic substances and organic substances. So what are the raw materials for cement grinding aids?Inorganic substances are mainly fly ash, graphite, carbon black, gypsum and inorganic salts. Most of

Polycarboxylic acid is a new type of admixture, which has high water reduction rate and high adaptability, can improve the workability of concrete, and improve the workability and quality of concrete construction. Precautions for the use of polycarboxylic acid admixtures for concrete are embodied in

In the field of cement grinding aids, the early alcohol amine compounds used in grinding aids were mainly triethanolamine. Because triisopropanolamine has better dispersibility and later strength than triethanolamine, with the development of the cement industry and intensified competition, the appli

Preventive measures for peeling of concrete pavement1.Strictly control the quality of concrete materials(1) Control of concrete mixing materialsMedium and coarse sand should be selected, and all indicators should be consistent with national standards. The use of washed sand and sea sand is strictly

Concrete has many characteristics, including low price, high wear resistance and durability, and multiple sources of materials. The application of construction engineering to it is very extensive, but during the construction of concrete pavement, because of various reasons, the peeling phenomenon of
