Silica sol yog ib qho kev daws teeb meem hauv cov silicoidal ntawm silicon dioxide yog discersed hauv dej, tseem hu ua Silica Dol lossis silica hydrosol. Cov tsos yog feem ntau milky dawb lossis lub teeb xiav kev daws teeb meem. Feem ntau ntawm lawv yog ruaj khov alkaline, thiab ob peb yog acidic. Cov concentration ntawm sio2 hauv Silica sol yog feem ntau 1 {0}%, thiab tuaj yeem ncav 50% thaum lub siab. Thaj chaw tshwj xeeb thaj tsam ntawm Silica sol sollles yog 50 ~ 400M2 / g, thiab cov particle loj li cas yog feem ntau 5 ~ 100nm, uas yog, nws yog nyob ntawm nanoscale. Piv nrog rau cov dav dav nrog ib tug particle loj ntawm 0.1 ~ 10.7μm, nws cov lus yog qhov me dua.
Cov txheej txheem ntau lawm ntawm Silica sollica yog suav nrog cov hauv qab no:
Ion sib pauv resin txujci: hom no siv cov khoom sib pauv hluav taws xob kom kho cov dej qab zib thiab npaj silica sol los ntawm kev tshem tawm Sodium ions hauv kev daws. Ion pauv cov resins feem ntau yog hla cov organic polymers muaj cov pab pawg acidic, xws li cov pab pawg sulfonic acid thiab cov pab pawg ua si. H + ions hauv cov txheej txheem no tuaj yeem yog ionized thiab sib pauv nrog lwm txoj hauv paus kom tau txais silica sol.
Sulfuric acid kev tswj hwm: Cov qauv no siv cov sulfuric acid rau neutralize lub khob dej los ntawm kev tswj hwm lub ph, txias thiab lwm yam kev daws teeb meem ntawm kev daws teeb meem. Nyob rau hauv cov xwm txheej tsim nyog, cov roj siv lead ua ntxiv, thiab tom qab ntawd cov khoom lag luam sillica tuaj yeem tau txais los ntawm kev kub siab thiab kev ua kom huv. Tag nrho cov txheej txheem yuav tsum tau tswj cov txheej txheem xws li NA + qhov kev daws teeb meem, qhov kub kub, ph ntawm kev daws teeb meem thiab lwm lub sijhawm.
Kev siv tshuab hluav taws xob electrodialysis txoj kev: Cov txheej txheem no npaj Silica Sol los ntawm kev siv hluav taws xob. Cov ntaub ntawv roj hluav taws xob tau ntxiv rau cov khoom siv hluav taws xob hluav taws xob, thiab cov khoom siv ceev, thiab lwm yam ntawm cov tshuaj tiv thaiv hluav taws xob, thiab thaum kawg silica Sol cov khoom tsim Cov. Cov txheej txheem ntws ntawm cov qauv electrodialysis txoj kev suav nrog cov kauj ruam ntawm cov ntaub ntawv hluav taws xob, thiab hluav taws xob cov txheej txheem electrodialysis txheej txheem.
Lwm txoj hauv kev: Ntxiv rau cov txheej txheem saum toj no, muaj lwm txoj hauv kev los npaj silica sol, xws li txoj kev gelation, cov pa roj Silica txoj kev thiab cov qauv kev faib tawm. Cov hau kev no txhua tus muaj lawv tus kheej cov txheej txheem ntws tawm thiab kev thov.
Txhawm rau tiv thaiv cov kev lag luam hauv qab tam sim no, tawg los ntawm kev sib txuas lus ntawm kev lag luam sillica ntawm cov khoom lag luam sillica ntawm cov khoom lag luam sillica ntawm cov khoom lag luam sillica thiab cov khoom siv sib txuas ntawm silica thiab cov pab pawg sib pauv. Cov pab pawg no yuav tshaj tawm cov ntaub ntawv kev lag luam silica, cov haujlwm kev lag luam, tso cov lag luam kev xav tau, thiab sib tham txog kev kawm thev naus laus zis tshiab kawg. Upstream and downstream related companies are welcome to join the group to participate in technology, supply and demand, industry information and other exchanges.
