This product is non-toxic, non-irritating, has good water solubility, will not hydrolyze metamorphism. And with a variety of components have good compatibility. As the main raw material used in polycarboxylic acid cement water-reducing agent, the synthetic polycarboxylic acid high-efficiency water-r

Polycarboxylic acid water reducer is known as the third generation of high performance water reducer.

Polycarboxylic acid water reducing agent is a commonly used cement and concrete water reducing agent, which has the effect of reducing water and slumping. The rational use of polycarboxylic acid water reducer is more effective.1. The water reduction rate fluctuates, which is not easy to control in t

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

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

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

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 early 19th century, dispersive admixtures were used. However, in the 1960s, sulphonated melamine formaldehydes and analogous naphthalene derivatives were introduced. Nowadays, new admixtures based on polycarboxylate ethers are being developed. Polycarboxylate ethers possess structural characteristics that provide more fluid concrete, which is more resistant to segregation and exudation as compared to that prepared with the previously known superplasticizers. Polycarboxylate ethers have been commonly utilized to enhance the flow ability of cementitious materials. Moreover, polycarboxylate ether is one of the most effective types of plasticizers, water reducer, and disperser which promotes excellent flow ability, high strength, workability, and pump ability, and efficient dispersion for gypsum, cement, and ceramic materials.

Polyether monomer in the Chinese market mainly refers to methoxy polyethylene glycol (MPEG), allyloxy polyethylene glycol (APEG), tresylated polyethylene glycol (TPEG) and isobutylene alcohol polyoxyethylene ether (HPEG). The field in which polyether monomer finds most application comes to polycarbo
