What is the cause of water reducing agent deterioration mildew
What is the cause of water reducing agent deterioration mildew? Any item has a shelf life, water reducer is also the same. If the use of water reducing agent deterioration, there will be many hidden dangers, and water reducing agent may deteriorate in the shelf life, then what are the reasons for the deterioration of water reducing agent?
1. The deterioration of water reducing agent has the phenomenon of light fluff or wadded plaque on the liquid level, the floating matter of discrete island chunks, string bubbles emerge, and even the plaque is covered with the whole liquid level, the suspended matter of thick green, brown, black, and accompanied by the generation of rotten sour odor gas.
2. The deterioration of water reducing agent is generally caused by the compound of sodium gluconate. Microorganisms can grow mildew on the surface of a polymer under appropriate temperature and humidity conditions. However, the polymer system contains plasticizers and oil compounds, especially the compounds containing fatty acid structure are easy to infect mold.
3. In hot and humid environment, the secretion of mold enables bacteria to parasitize and multiply, which intensifies biodegradation. Aspergillus Niger is widely used in industrial production to produce sodium glugluate by fermentation, which will produce Aspergillus Niger residue. If the production is not strictly controlled, there will be glucose and Aspergillus Niger residue, providing nutrition for the reproduction of microorganisms.
4, when a variety of breeding conditions superimposed on each other, mold explosion, water reducing agent will deteriorate. In addition, it is related to the storage environment, high temperature will aggravate the movement of macromolecular chains, chain decomposition, irregular fracture and thermal decomposition, leading to the deterioration of polymers, the higher the temperature, the greater the activity of microorganisms, the faster the mildew speed of water reducing agent.
