Lub ntsiab ntawm defoamers suav nrog silicone, polyether, roj ntsha, thiab lwm yam. Cov kev faib tawm ntawm cov roj ntsha yog nyob ntawm kev sib xyaw thiab cov xwm txheej thov. Hauv qab no yog cov ncauj lus kom ntxaws thiab cov yam ntxwv:
1. Kev faib tawm los ntawm cov tshuaj lom neeg
Silicone defoamer
Cov khoom xyaw: polydimethylsiloxane (PDMS, uas muaj cov roj silicone), uas muaj 20 mn \/ m) thiab tuaj yeem kho cov qauv ua npuas ncauj.
Nta: Kev kub siab tsis kam ({}} degree ~ 200 degree), tsim nyog rau cov tshuaj tiv thaiv kom ruaj khov, khoom noj, tshuaj thiab lwm thaj teb.
Qhov tsis zoo: Kev siv ntau dhau yuav ua rau cov seem (xws li clogging dej phwj kev kho mob).
Polyether Defosamer
Cov khoom xyaw: Ethylene Oxide \/ Propylene Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide oxide oxide oxide oxide oxide cov tub luam ntawv, uas yoog raws qhov kub thiab txias ntawm huab cua.
Nta: muaj zog tiv thaiv muaj peev xwm thiab kub tsis kam, siv tshuab hluav taws xob ntau dua li fermentation thiab ncig ua dej.
Qhov tsis zoo: Cov tsis zoo defoaming detability thiab ntau qhov kev hloov pauv tau.
Cov roj fatty acids thiab cov roj ua rog
Cov khoom xyaw: palmipsic acid, stearic acid thiab lawv esters, ntuj tiv thaiv.
Nta: Zoo biodegradity, feem ntau siv hauv kev ua zaub mov thiab chaw muag tshuaj.
Cov roj ntxhia tiv thaiv
Cov khoom xyaw: roj dawb lossis cov roj hydrocarbon, compounded nrog hydrophobic hais (xws li silica).
Nta: Qes nqi qis, muaj txiaj ntsig tsawg, haum rau scenes nrog cov kev tiv thaiv qis cov kev txwv tsis pub muaj xws li cov nplua lim dej.
Polyether Hloov Hloov Silicones
Cov khoom xyaw tseem ceeb: Silane ether copolymers, sib txuas ntawm qhov zoo ntawm polyete thiab silicone.
Nta: Zoo dispersibilibility, muaj zog los tiv thaiv kev ua npuas ncauj, haum rau cov tshuab (xws li High-Size Wastewater).
Biodegradable defoamers
Cov khoom xyaw: zaub roj (xws li roj tsuag tsuag) lossis tsis tu ncua polyether.
Nta: Ib puag ncig phooj ywg, tsim nyog rau cov chaw rhiab (xws li kev ua haujlwm dej paug).
2. Lwm txoj kev sib koom ua ke
Los ntawm daim ntawv: emulsion hom, roj hom, khoom patalle ib yam, thiab lwm yam.
Los ntawm daim ntawv thov thaj chaw: TSHUAJ TSHWJ XEEB RAU Textile, papermaking, txheej, khoom noj, thiab lwm yam.
