Why does the polycarboxylic acid water reducing agent deteriorate? What factors are related to the deterioration of polycarboxylic acid water reducing agent?

Polycarboxylic acid water reducing agent is a commonly used concrete additive, which can effectively reduce the water-cement ratio of concrete and improve the fluidity and uniformity of concrete, so as to improve the strength and durability of concrete. However, polycarboxylic acid water reducing agent can also deteriorate in the process of use, which brings certain risks and hidden dangers to the construction and use of concrete. Then, why does the polycarboxylic acid water reducing agent deteriorate? Firstly, the deterioration of polycarboxylic acid water reducing agent is related to its nature. Polycarboxylic acid water reducing agent is a kind of polymer compound, its molecular structure is complex, containing a large number of carboxylic acid groups and polyoxyethylene groups and other functional groups. These functional groups will undergo chemical reaction under certain conditions, resulting in changes in the properties of the polycarboxylic acid water reducing agent and loss of the original water reducing effect. In addition, polycarboxylic acid water reducing agent is also easily affected by oxidation, light, high temperature and other factors, which leads to its deterioration.

Secondly, the deterioration of polycarboxylic acid water reducing agent is related to the problems in its production and storage process. The production of polycarboxylic acid water reducing agent needs certain technology and equipment support; if there are problems such as improper operation, poor quality of raw materials and unqualified production equipment in the production process, it will lead to the quality of polycarboxylic acid water reducing agent and even deterioration. In addition, polycarboxylic acid water reducing agent also needs to pay attention to moisture-proof, sun-proof, high temperature-proof and other problems in the storage process, otherwise it will also lead to its deterioration. Finally, the deterioration of polycarboxylic acid water reducing agent is also related to its use. Polycarboxylic acid water reducing agent needs to be added into concrete according to a certain proportion in the process of using; if the amount added is too much or too little, it will affect the performance and quality of concrete. In addition, the use of polycarboxylic acid water reducing agent also needs to pay attention to the construction environment, concrete mixing ratio, mixing time and other factors, otherwise it will also lead to the deterioration of polycarboxylic acid water reducing agent.
To sum up, the deterioration of polycarboxylic acid water reducing agent is the result of a variety of factors, only in production, storage and use. Through the process of strict control of a variety of factors, in use to ensure the quality and effect of polycarboxylic acid water reducing agent. Therefore, when using polycarboxylic acid water reducing agent, it is necessary to choose regular manufacturers and suppliers, and follow the correct use method and operation procedure to ensure the quality and construction effect of concrete.
Tongrun Polycarboxylic Acid High Performance Powder Water Reducer 26C is a powder water reducer made by adding liquid water reducer to various additives such as polymerisation blocking agent, anti-binding agent, etc., and then adding stabiliser after pre-screening in spray drying tower, and retaining the excellent properties of water reduction, slump preservation and durability of the water reducer, and it can adapt to various construction environments.
