The precautions of polycarboxylic acid water reducing agent mainly include the following six points:1. There is a problem with the adaptability of cement. For some cements, the water reduction rate is low and the slump is large. Therefore, when the cement adaptability is not good, the concrete trial

Triethanolamine is an important additive in water-based cutting fluids. It has multiple functions in water-based cutting fluids:1.Synthetic water-soluble lubricantAt present, most oily agents with good lubricating properties are water-insoluble. Triethanolamine has three -OH. By controlling the rati

Cement companies generally roughly divide grinding aids into two categories, "enhancing" and "increasing production." How should I choose? It is generally thought that if you want to increase the strength, you choose the "enhanced" grinding aid, and if you want to increase production or save electri

The slag cement has the advantages of low heat of hydration, high strength at the later stage, inhibition of alkali aggregate reaction, and resistance to sulfate corrosion, and has been used in a large number of projects. When producing slag cement, the slag is less abrasive than the clinker. So how does slag cement behave under the action of TEA and TIPA?

Cement grinding aid companies, as promoters of introducing grinding aid products into cement production, guide cement enterprises to correctly understand and use cement grinding aids, and help cement enterprises correctly judge certain problems in the application process of grinding aids, which will

Triethanolamine is a colorless to pale yellow viscous liquid. It can react with various acids to form esters and amide salts. It can also corrode copper, aluminum and its alloys. Triethanolamine has a wide range of effects. what's the effect? What is its main use?1. Used as plasticizer, neutralizer,

As a new generation of water reducing agent, polycarboxylic acid water reducing agent is widely used in concrete engineering, but there are still some problems in the process of use that are difficult and difficult to solve. Therefore, some matters should be brought to our attention during use.

In the past 40 years, the application of water-reducing agents in concrete has developed rapidly. As a new generation of water-reducing agents, polycarboxylic acid-based water-reducing agents have become an essential component for the preparation of high-performance concrete.

Cement is an indispensable basic raw material in the construction of national infrastructure and economic development. However, with the increasing pollution of the environment, the production of cement is still in a high energy consumption industry.Portland mineral cement is widely used in the market.

Polyethylene glycol (PEG) is very common and useful in various industries. It mainly neutralizes the acidity of fillers in rubber, accelerates the vulcanization rate and crosslinking density, has good water solubility, and has many organic components. Good compatibility, with excellent lubricity, moisturizing and dispersing properties. Generally, PEG-4000 is used in the rubber, because the molecular weight of 4000 is solid flake, easy to process, easy to add, difficult to precipitate, and the polymer with medium molecular weight has better compatibility with rubber.
