“N” Ways to Eliminate Foam with Building Material Defoamer
Aug 16, 2024
Building materials is a general term for materials used in civil engineering and construction, including a series of construction and decoration materials such as cement, concrete, wood, stone and so on. 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 the hazards of foam in construction materials? 1. A large amount of foam will affect the performance and strength of the product, so that the strength of building materials is not up to standard, resulting in quality problems; 2. Too much foam will also affect the appearance of building materials, easy to make the surface of building materials uneven, defects; 3. Excessive foam will slow down the production process of building materials, extend the construction cycle of building materials, resulting in unnecessary costs; 4. A large number of foam is difficult to remove cleanly, will remain part of the construction equipment, resulting in a decline in the utilisation rate of construction equipment, shortening its service life.
In the face of the various problems brought about by the blistering of construction materials, why would we recommend building materials defoamer? What are the advantages and characteristics? 1. Fast defoaming and foam suppression, added to the building materials can quickly penetrate the foam inside to achieve defoaming and foam suppression; 2. Stable performance, will not affect the performance and strength of building materials after use, and will not change the colour and appearance of building materials; 3. Good water solubility, fast dispersion, once added, it can be quickly dispersed, no new precipitation, no oil bleaching.
