Lub hauv paus tseem ceeb ntawm defoamers suav nrog silicones (xws li roj av (xws li emulseescees (xws li cov khoom siv hluav taws xob (xws li cov nqa khoom), thiab cov nqa khoom, thiab lwm yam).
Hauv qab no yog cov ncauj lus kom ntxaws thiab cov yam ntxwv:
1. Silicone defoamers
Cov khoom xyaw: polydimethylsiloxane (silicone roj) thiab nws cov derivatives.
Cov yam ntxwv Interertness, muaj mob kub thiab qis thiab qis {0}} degree rau 130 degree), tsawg nras kev ceev, ceev nrawm nrawm.
Daim ntawv thov: Textile, papermaking, tshuaj lom neeg, khoom noj khoom haus (xws li tofu ua) thiab lwm yam lag luam.
2. Polyether Defoamers
Cov khoom xyaw: Polyether cov tebchaw xws li polyoxyethylene (Peo) thiab polyoxyprropene (PPO).
Cov yam ntxwv: muaj zog hydrophilicity, ntev los tiv thaiv lub sijhawm ua npuas ncauj, tsis muaj tshuaj lom (haum rau kev lag luam khoom noj (xws li kua txiv, fermentation cov txheej txheem).
Sub-hom: Tawm Polyether, Terminal Esterified Polyether, thiab lwm yam.
3. Cov ntxhia roj tsis txaus ntseeg
Cov khoom xyaw: cov roj ntxhia (kerosene, diesel) compounded nrog ciab lossis silica.
Cov yam ntxwv: Tus nqi qis, ib puag ncig phooj ywg, tab sis kev sib xyaw tsis zoo.
Daim ntawv thov: tsho me, inks thiab lwm cov liaj teb uas tsis tas yuav muaj gloss.
4. Lwm hom
Surfactants: xws li emulsifiers, defoaming yog tiav los ntawm dispersing foaming tshuaj.
Compound Type: Silicone Polyether Defoamer (silicone + polyether), nrog kev ua tau zoo dua.
Khoom noj khoom haus tshwj xeeb: xws li cov roj carbon ntau roj ua roj (siv hauv cov khoom noj), propylene glycol polyether (ib qho ntxiv).
5. Ib qho khoom xyaw
Cov cab kuj: dej lossis roj ntxhia, los pab cov khoom xyaw nquag.
Stabilizer: Thickener (xws li polyethylene ether) los txuas lub sijhawm txiav txim.
