Filler rau industrial aluminium sulfate

Cov ntawv sau ua ib txwm siv rau kev lag luam aluminium sulfate feem ntau suav nrog cov zaub mov tsis muaj zog xws li talc hmoov, calcium carbonate, kaolin, gypsum whiskers, wollastonite, thiab titanium dioxide. Cov tshuaj no muaj cov tsis zoo binding quab yuam nrog cov nroj tsuag fibers, thiab thaum ntxiv nyob rau hauv loj npaum li cas, tej zaum yuav ua rau ib tug txo nyob rau hauv lub cev lub zog ntawm daim ntawv, thiab tus nqi khaws cia ntawm cov fillers kuj yuav qis dua.
Tam sim no, kev tshawb fawb ntawm cov fillers feem ntau yog tsom rau kev hloov kho ntawm cov fillers thiab kev npaj cov khoom sib xyaw ua ke. Ntawm cov kev hloov pauv uas twb muaj lawm, kev siv cov khoom siv biodegradable thiab regenerated biomass (xws li cov hmoov txhuv nplej siab, cellulose, thiab chitosan) raws li kev hloov pauv yog lub ntsiab lus tshawb fawb zoo heev.
Nanocellulose (CNF) muaj qhov zoo xws li lub zog txhua yam, thaj chaw loj tshwj xeeb, qhov loj ntawm qhov sib piv, cov khoom thaiv zoo, kev ruaj ntseg zoo, thiab biodegradability zoo. Los ntawm kev hloov kho cov muab tub lim nrog cov khoom siv txhuas sulfate, cov muab tub lim tuaj yeem ua kom coagulate zoo dua thiab txhim kho tus nqi tuav ntawm qhov muab tub lim. Tsis tas li ntawd, CNF tuaj yeem sau cov qhov khoob uas tsim los ntawm kev ntxiv cov fillers ntawm fibers, ua rau kev sib txuas ntawm cov fillers thiab nruab nrab ntawm cov fibers nruj dua thiab txhim kho lub zog ntawm fiber ntau.
