- The development status of DEIPA in China and its future development prospects and application in cement grinding aidsThe 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 applicationsGreen 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.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.

- Effect of Diethanol Monoisopropanolamine on Grinding and Properties of Portland CementEffect 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 .
- Application of limestone powder in cement concreteTriisopropanolamine (TIPA) is one of the commonly used components of cement grinding aids. Currently, TIPA is for silicates The strength and hydration properties of cement and Portland cement containing fine limestone particles have been studied.
- Application of triisopropanolamine in cement concreteApplication of triisopropanolamine in cement concreteTriisopropanolamine can be used together with some superplasticizers used in ready-mixed concrete, such as polyether polycarboxylate water Triisopropanolamine was mainly used in petrochemical and daily chemical industries.
- Polycarboxylate superplasticizerPolycarboxylate superplasticizer has excellent performance such as high water-reducing rate, small slump loss and no pollution. It is an important component of high-strength and high-flow concrete and high-volume fly ash concrete.

After more than 20 years of hard work,Company News September 17, 2018
- Different molecular weight structures of polyethylene glycol and its application fieldsDifferent molecular weight structures of polyethylene glycol and its application fields With the continuous expansion of the application field of polyethylene glycol, the production of polyethylene glycol in countries and regions such as Europe, America and Japan has increased rapidly. There are various types of polyethylene glycol products in foreign countries. The structure of poly(ethylene glycol) is HOCH2[CH2OCH2] nCH2OH or H[ OCH2CH2] nOH is a general term for ethylene glycol polymers having an average molecular weight of 200 to 8000 or more. With the difference in average molecular weight, the properties also vary.
