What is a polycarboxylate superplasticizer?

Polycarboxylate superplasticizer is used primarily in cement concrete to act as a dispersant. It is composed of polymers containing sulfonic acid group (-SO3H) and carboxyl groups (-COOH) or derivatives of them and features high efficacy, environmental protection, and security.

HSB aliphatic superplasticizer

HSB (High Strence Bing) is a carbonyl paraldehyde synthesized by high molecular sulfonation. The hydrophobic main chain for aliphatic hydrocarbons, in the future referred to as HSB, is a green high, efficient water-reducing agent developed in Qingdao HS. This product does not pollute the environment and does not harm human health. It has broad applicability to cement, noticeable enhancement effect to concrete, slight slump loss, low temperature no sodium sulfate crystallization phenomenon, widel

Advantages and disadvantages of polycarboxylic acid superplasticizer

In many concrete projects, traditional high-efficiency concrete such as the naphthalene series can not meet the needs of engineering and more due to the limitation of technical performance. The new generation of a polycarboxylic acid series high-performance water-reducing agent, which has attracted much attention at home and abroad, has achieved an effective molecular structure design according to the action mechanism of dispersed cement. It has the super dispersive type, which can prevent the s

Synthesis of polycarboxylic acid superplasticizer

In situ polymerization grafting method: using polyether as the medium of unsaturated monomer polymerization, the main chain polymerization and the introduction of the side chain can be carried out at the same time, the process is simple, and the molecular weight of the synthesized water-reducing agent can be controlled to a certain extent, but the esterification reaction involved in this method is a reversible reaction, resulting in a low grafting rate in aqueous solution, which has been gradual

"Water reduction" mechanism of polycarboxylic ether based superplasticizers

Today's concrete superplasticizers These are made from a combination of various materials like polycarboxylate water–reducing mother liquor and/or polycarboxylate shrink-preserving mother liquor. It is the most important role for water-reducing mothers in superplasticizer. Although it is possible that the quantity of the mother solution may change with the changes in concrete, I've never seen water-reducing mothers added to superplasticizer. Perhaps because the sand quality is too high. The a
