Many bubbles often appear during cement self-leveling construction. If they are not eliminated in time, the surface smoothness and brightness will be affected after solidification, and the quality will be affected. Therefore, many merchants will buy mineral oil defoamers for defoaming, but some friends want Ask about its working principle and scope of application, then revisit mineral oil defoamer!
Mineral oil defoamers give self-leveling a new look
First of all, the raw material is the only criterion to determine the performance of a product, and mineral oil, peppermint oil, vegetable oil, white oil, and corn oil are insoluble in any foaming medium, which is one of the main components of mineral oil defoamer. They all have the characteristics of low surface tension. In addition, polyoxyethylene, cocoic acid diethanolamide, emulsifier, and dispersant are added through special process refining, and then high-speed sprayer is used for shearing and then filtered to obtain high-quality products. Stabilized mineral oil defoamer.
Therefore, it can be used in cement self-leveling foaming for defoaming and anti-foaming because self-leveling contains a large number of active ingredients, such as concrete gel, quartz sand, lime powder, water reducer, coagulant, etc., which are mixed with water During the construction, the flow impact force will produce a lot of air bubbles, and because the mud is too viscous, the bubbles are not easy to break, so adding mineral oil defoamer can quickly neutralize and reduce the surface tension during stirring, so that the surface of the bubbles will be thinned and discharged. gas, while also preventing the formation of air bubbles.
Mineral oil defoamers are not just for self-leveling
In the chemical industry and food industry, such as papermaking, coating, fermentation, food baking or refining processing, metal cleaning, ink printing are all suitable for the use of mineral oil defoamers, they can not avoid the generation of foam during production and processing, and at the same time Mineral oil defoamer will not have other effects on the product, and its resistance to harsh environments enables it to be used in a wide range of applications.
