N Ways to Eliminate Foam with Building Material Defoamer
Building materials is a general term for materials used in civil engineering and construction, including cement, concrete, wood, stone and a series of construction and decoration materials. In the production and actual use of building materials, foam often appears due to irrational grading and other reasons. Why does foam appear in the production and use of building materials? 1. Unreasonable grading, too much coarse aggregate and too little fine aggregate lead to large gaps in the building materials, which is easy to produce foam; 2. Inappropriate size of aggregate, too high content of needle and flake particles, leading to the emergence of foam; 3. In order to improve the performance and strength of building materials, often add a certain proportion of chemical additives, such additives belong to the surfactant, with foaming properties; 4. The mixing operation of the equipment and the uneven surface of the substrate make it difficult for air to escape and form foam. What are th...
