Polyurethane ua npuas ncauj Filler

Polyurethane bio-fillers yog tsim rau cov dej khib nyiab xws li cov dej khib nyiab siab, ntau yam dej khib nyiab, ua kom cov dej khib nyiab, cov dej khib nyiab txhua hnub, cov dej khib nyiab, thiab cov dej phwj hauv nroog. Lub polyurethane sponge tsim los ntawm peb lub tuam txhab cov txheej txheem tshwj xeeb yog siv los ua tus cab kuj ntawm kab lis kev cai kab lis kev cai. Vim hais tias ntawm qhov tshwj xeeb ntxeem tau network qauv ntawm cov kab mob lom, qhov chaw tshwj xeeb ntawm cov kab lis kev cai kab lis kev cai tau zoo heev. Lub ntsiab lus tseem ceeb yog kom paub txog cov tshuaj tiv thaiv nitrosation nyob rau sab nrauv ntawm ib qho khoom siv roj ntsha hauv lub tank aeration thiab denitrification ntawm nitrite nyob rau hauv sab hauv, uas tsis yog tsuas yog yooj yim lub cev adsorption tab sis kuj zoo thiab tsis zoo nqi ntawm lub ntiajteb txawj nqus. Yog li hais tias cov neeg nqa khoom ntog qee cov cationic active pawg thiab hydrophilic pawg xws li hydroxyl pawg, thiab cov dej phwj tuaj nrog cov nqi tsis zoo ntawm cov kab mob los tsim cov ntawv cog lus, valence ruaj khi kom cov kab mob thiab cov enzymes lom tau ruaj khov ntawm cov cab kuj.

Cov yam ntxwv ntawm polyurethane biological muab tub lim yog tus nqi qis, yooj yim installation, lub neej ntev kev pab cuam, load tsis kam, tsis muaj blockage, zoo hydrophilicity, siab biological kev ua si, loj tshwj xeeb deg cheeb tsam, yooj yim loj hlob thiab yooj yim rau poob ntawm biofilm, thiab kev kho mob nyhuv.
