Latest research and development progress and market development trend of China's concrete admixture industry The China Building Materials Federation Concrete Admixture Branch conducts a nationwide survey on the production of concrete admixtures every two years. The purpose is to grasp the latest developments in the industry and provide an accurate basis for formulating industry development policies. The investigation has been going on for more than ten years.

The use of grinding aids can improve the grinding efficiency, improve the performance of cement, and achieve energy saving and emission reduction. At present, with the continuous improvement of the requirements for cement and building materials and the increase in cement production, more and more cement plants have begun to use grinding aids and achieved satisfactory results.

At present, the domestic grinding and grinding agents for research and application are liquid and solid. The formula consists mainly of single or composite products such as amines, polyols and acetates. The basic components are mostly organic surface active substances. Triethanolamine and ethylene glycol are highly polar surfactants and are used as cement grinding aids.

Research progress and development trend of cement grinding aids The application of cement grinding aids has become more and more intensive with the development of the cement industry. Since domestic cement production accounts for more than 60% of the world's total output, and most of the production cement is taken locally, the research on cement grinding aids has been active, while abroad. Research is relatively mature, in relative。Stagnant state. The new multi-functional grinding aid has always been the development trend of grinding aids. As the price of cement declines, the use of grinding aids has become the focus of attention in the future.

High-efficiency water reducer was first invented and used by Japanese people. In addition, other economically developed countries are also at the forefront of the world in the development of high-efficiency water reducers. Due to the unbalanced development of concrete technology in China, performance and cost issues have affected the development of polycarboxylate superplasticizers. At present, the research on polycarboxylate superplasticizer in China is still in its infancy, and the synthesis method of polycarboxylate superplasticizer is continuously explored through molecular design. Many units have achieved some better.

The development status of DEIPA in China and its future development prospects and application in cement grinding aids China's DEIPA is mainly used in cement grinding aids. The dosage is 0.5 to 10,000 parts per million of cement. It can be combined with polyol, triethanolamine and harmless inorganic salts. It can be designed as a high-volume product. It can be used to enhance multi-mixed materials. It can also be designed as a low-volume product for high-grade cement to achieve a comprehensive effect of enhanced production

Green chemistry concept in polyethylene glycol applications The response of PEG will continue to attract further exploration of PEG as a solvent.And the support of the catalyst, and the grafting functionalization with the ionic liquid with the advantages of stable and almost no volatility; and the application in combination with microwave technology and biochemistry, which helps to improve the yield of the organic reaction and optimize Reaction time; while PEG as the medium of reaction, it will be more inclined to recycle some expensive metal catalysts。

A nonionic surfactant, a fatty alcohol polyoxyethylene ether, which has different products due to different carbon numbers. Surfactants come in a wide variety of applications and are widely used, from the formulation of detergents, the construction of primordial cells, to the delivery of drugs. Fatty alcohol polyoxyethylene ether (AEO), also known as alcohol ethers and alcohol ethoxylates, is the fastest growing and most widely used nonionic surfactant. In recent years, it has developed extremely rapidly, and has partially replaced sodium alkylbenzene sulfonate.

Shijiazhuang Hebei Haisen has first-class technology and perfect equipment system. I believe that there will be many partners who are interested in us. Welcome to the Vietnam exhibition to discuss with us. We held an exhibition in Vietnam in November 2018. As a Chinese company participating in the exhibition, we are very proud. Shijiazhuang Hebei Heisen gave us the opportunity to go out to participate in this exhibition. At the same time, show me, our products and services. Our company attaches great importance to this exhibition.

Effect of Diethanol Monoisopropanolamine on Grinding and Properties of Portland Cement The cement-soil mixing method is generally a cement as a curing agent, which utilizes a series of physical, physical, chemical and chemical reactions between cement and soft soil to harden the soft soil into cement soil with certain strength and water stability. Ground treatment method to improve foundation strength and increase deformation modulus .
