Moemeli oa phoofoa-sehlahisoa se secha

Defoamer ea phofoe entsoe ka polymerized ka mokhoa o khethehileng oa polysiloxane, emulsifier e khethehileng le polyether defoamer e sebetsang haholo. Kaha sehlahisoa sena ha se na metsi, se sebelisoa ka katleho lihlahisoa tsa phofo ntle le metsi. Litšobotsi ke bokhoni bo matla ba defoaming, tekanyo e nyane, khatello ea foam e tšoarellang nako e telele, botsitso bo botle ba mocheso, metsi a mangata, ha ho na litla-morao, lipalangoang tse bonolo, joalo-joalo E na le ts'ebetso e matla ea ho senya le ho thibela foam mocheso o phahameng le tharollo e phahameng ea alkalinity.

Ho na lemefuta e mengata ea li-defoamers, ho kenyeletsaDefoamer e thehiloeng ho Oli ea Liminerale, Organic Silicon Defoamer, Polyether Defoamer, Defoamer e phahameng ea Carbon Alcohol, Emulsion-based leSphofo e tala. Li-defoam kaofela li na le thepa e latelang:

1. Bokhoni bo matla ba ho tlosa lekoba le tekanyo e tlase;

2. Ho eketsoa ha li-defoamers ho ke ke ha ama thepa ea motheo ea tsamaiso;

3. Khatello e tlaase holim'a metsi;

4. Ho leka-lekana hantle ka holimo;

5. Dispersibility e ntle le permeability;

6. Ho hanyetsa mocheso o motle, ho hanyetsa acid le alkali;

7. Ho tsitsa ha lik'hemik'hale le khanyetso e matla ea oxidation;

8. Ho qhibiliha ha khase e ntle le ho phunyeletsa;

9. Low solubility ka tharollo foaming;

10. Tšireletseho e phahameng ea 'mele.
