Misunderstandings and suggestions when using antifreeze or antifreeze pumping agent Lingbi antifreeze price Si County antifreeze manufacturer

(1) Many construction units believe that adding antifreeze is foolproof. Improper on-site insulation and maintenance measures result in the antifreeze not being able to fully exert its due effect, causing the concrete to freeze. If there is a quality problem, all the responsibility will be passed on to the commercial concrete company. Some concrete mixing plants do not correctly understand the concept of whether the antifreeze itself does not freeze or ensures that the concrete does not freeze. They believe that the antifreeze itself will not freeze. They do not insulate the antifreeze storage equipment and pipelines, resulting in continuous low temperatures. After the lower pipeline is frozen, the admixture pump cannot pump up, affecting normal production. Antifreeze can make concrete harden at negative temperatures and achieve expected performance and sufficient strength under specified curing conditions. The antifreeze components usually use substances with a lower minimum co-melting point to form tiny crystals and lower the freezing point. Promote negative temperature hydration conditions to enhance the anti-freeze ability of concrete.

(3) When preparing antifreeze pumping agents or antifreeze agents, admixture manufacturers should adjust the formulation of antifreeze pumping agents according to the various materials and different requirements of each commercial concrete mixing station. Ratio materials to meet the specific requirements of the project, especially the preparation of antifreeze pumping agents. While optimizing antifreeze components, it can increase the water reduction rate, greatly reduce the water consumption of single concrete, reduce the water-cement ratio, and improve the hydration liquid phase. ion concentration. Use high-quality air-entraining agents to keep the air content of concrete between 3% and 4.5%. Optimize antifreeze to ensure good construction performance of concrete, and combine antifreeze and antifreeze effects to increase the frost resistance durability of concrete.
