Polyether Defoamer
Polyether-E50
Chemical Nature
This strain is made of polyether as the main raw material and refined with various active additives. Due to the large gas content of polycarboxylic acid mother liquor itself, the appearance of concrete bubbles is more and more uneven. The addition of this defoamer can eliminate the excess large bubbles in the concrete without affecting the beneficial bubbles produced by the water reducing agent. It can not only improve the structure of concrete holes and the degree of compaction, but also control the slump loss of concrete, better control the problems of concrete entrain, slow setting, bleeding and so on, and become an indispensable component in the concrete mix ratio. The defoamer does not break milk, does not bleach oil, has excellent alkaline resistance, fast defoaming, lasting foam suppression, and will not cause any pollution to the environment.
Features of application
1, can effectively reduce the formation of bubbles and foam in concrete, mortar and other building materials.
2, good high temperature resistance
3, broad acid and alkaline resistance, especially suitable for anti-foaming and anti-foaming under alkaline conditions.
4, excellent high temperature resistance and shear ability.
5, excellent anti-foam and anti-foam performance, can play a role in very low concentration.
Usage
Used in the production of cement mortar, water reducing agent, concrete, and other production process of defoaming. Directly into the foaming system, before use must be stirred evenly, this product can be directly added or sprayed to use, can be diluted with water after use (need to use immediately), the general recommendation to add the amount of the total product is 0.1% ~ 0.5%, the amount should be adjusted by the user according to the test.
