Water reducers are usually composed of a mixture of various chemical components; some of them are surfactants. These chemicals, which tend to cause foaming, lead to the formation of large amounts of foam during use. A common method to eliminate this foam is to add a small amount of a water reducer or defoamer. http://s13.sinaimg.cn/mw690/007HYTaCzy7sZQZZB4U6c&690 Some people may ask why only a small amount of water reducer and defoamer is used, and not a large amount Given the severity of the foaming issue, Engineer Wang from Tianfeng Laboratory said that defoamers are developed specifically for water reducers; they work by targeting the components within those water reducers as well as the foaming substances, thereby eliminating or suppressing foam formation. Thanks to their strong defoaming capacity, they can eliminate foam quickly without leaving any residues, and usually only a small amount of defoamer is needed. The reference dosage is 0.1~0.8% added based on the proportion of the total amount of water reducers, with adjustments made as appropriate according to the defoaming capacity of one’s own product; for any doubts, professional customer service can be consulted. So, will the addition of defoamers affect the effectiveness of the water reducer? Engineer Wang from the laboratory appeared again to explain that the function of water reducers and defoamers is to eliminate foam, effectively removing or suppressing foam formation in foamy substances. It is precisely because of the effect of defoamers that water reducers enable an acceleration in project progress during use; after all, foam has a very serious impact on the manufacturing process, and it can even affect the quality of the final product. The construction industry has already been plagued by scandals involving substandard building projects; as a result, more businesses are beginning to pay closer attention to the quality of their products. They are thus very careful when selecting building materials, leaving no room for mistakes. This is also why so many customers choose water reducers and defoamers.
