The function of cement slurry defoamer The PH value of cement mortar is usually relatively high, so its alkalinity is also strong. In the preparation process of cement slurry, lime will react with water and release a large amount of human energy, resulting in a temperature rise. The silicon compound's main component of cement slurry defoamer and its acid and alkali resistance is very good. Under the premise of stable performance, the foam can be removed quickly, there will be no bad conditions such as demulsification floating oil, and it can cope with the instantaneous temperature change very well.
Its application has the following advantages: 1.Increase the stability of buildings Before using cement slurry defoamer, there will be more air bubbles in the construction process, affecting the overall structure of cement building materials after curing in the later stage. After using the defoamer of cement building materials, it can be directly added to the mortar in the production process of cement building materials, which can quickly destroy the bubbles and prevent them from being too large, thus ensuring that the cement slurry has full contact with the air and the overall structure is firm and stable.
2.Increase its surface smoothness Before using cement slurry, obvious blistering marks will appear on the surface of cement building materials, affecting the overall aesthetics and durability. After using cement slurry defoamer, defoamer can improve the fluidity of cement mortar, make the cement mortar more uniform, the surface more smooth, beauty, and durability have been greatly improved.
3.Speed up its curing speed Before using cement slurry defoamer, it takes a long time for cement building materials to solidify, and the hardness of solidified cement mortar is lower. After using the defoamer for cement building materials, the overall quality of cement building materials has been greatly improved because the defoamer prevents the formation of bubbles, the fluidity of cement mortar is better, the curing time is shorter, and the hardness is higher. Usage and dosage of cement slurry defoamer. For the use of cement slurry defoamer, we only need to know its usage and dosage. The dosage of cement slurry defoamer is generally 0.1-0.5%, and can be adjusted according to the foaming situation of cement slurry in actual use. The usage of cement slurry defoamer is also very simple, it only needs to be diluted with a small amount of water, and then it can be directly added to the foaming link of cement slurry. The amount of foam in cement slurry can be significantly reduced in a few minutes. And the subsequent foam will not continue to occur.
