Application Industry: Papermaking Industry Sewage Treatment PCB Cleaning
RK-653 is a kind of silicone - polyether defoamer. No silica lipids float after dispersion in the system.
Product property:
Good antifoaming at low concentration level
Strong universality, antifoaming and foam control under different aqueous at mid&low temperature
Easily disperse in water
Great performance above 60℃ in papermaking white water
Main physical and chemical properties:
Item | Range |
Appearance | Milky white emulsion |
Viscosity(25°C) | 100~300mPa·s |
Solid content | 30±1% |
pH value | 6.0～8.0 |
Application Process:
RK-653 could be added directly. The volume of addition is 0.5‰ ～0.6%. According to your specific conditions, optimum volume of addition could be adjusted. A certain concentration of Thickening water for dilution and volume of preservatives need to be added if it’s stored for a long time. If RK-653 is used immediately, you could add a certain proportion of water which the proportion is not too high, and should use it in time. During the stirring, the speed could not be too fast and mixed well is accepted.
