1. Kev Ua Haujlwm
Silica sol yog cov tshuaj colloidal, ntxhiab tsw thiab tsis muaj tshuaj lom. Cov mis mos molecular tuaj yeem raug qhia ua mSiO2 · nH2O. Vim tias cov colloidal hais tau zoo (10-20nm) thiab muaj qhov tshwj xeeb qhov chaw loj, cov lus lawv tus kheej tsis muaj xim thiab pob tshab, thiab tsis cuam tshuam rau lub ntuj xim ntawm cov khoom npog. Lub viscosity tsawg, thiab dej tuaj yeem nkag mus rau txhua qhov chaw nws tuaj yeem nkag mus, yog li thaum sib xyaw nrog lwm cov tshuaj, cov dispersion thiab permeability tau zoo heev. Thaum cov dej hauv lub silica sol evaporates, cov lus hais ua kom lub ntsej muag yog khov kho rau saum npoo ntawm qhov khoom, ua rau lub ntsej muag silicon-oxygen ntawm qhov hais, uas yog cov nplaum zoo.
2. Lub hom phiaj
Silica sol tuaj yeem siv dav hauv txhua qhov chaw ntawm lub neej vim nws zoo adhesion, siab kub tsis kam, zaj duab xis tsim, gelation, lub txim tau, thaj chaw loj tshwj xeeb, tsis muaj tshuaj lom, tsis muaj ntxhiab thiab lwm yam ntxwv.
1. Precision casting
Vim tias silica sol muaj cov nplaum zoo, tsis tshua muaj shrinkage thiab nws cov yam ntxwv ntawm qib zoo meej iav hloov dua siab tshiab ntawm qhov kub siab, nws tau dav siv ua lub plhaub binder hauv kev lag luam precision precision.
2. Cov ntaub ntawv refractory
Lub silicate refractory fiber ntau nrog silica sol yog cov khoom siv tseem ceeb, vim nws txuag hluav taws xob zoo thiab muaj kev tiv thaiv kub kub, tau siv dav ua cov khoom siv thermal rwb thaiv tsev hauv cov chaw lag luam thiab lwm cov khoom kub thiab khoom siv. Lwm yam amorphous refractory cov ntaub ntawv uas siv silica sol ua tus binder, vim tias lawv yuav tsis nqa ntau yam qis melting point oxides, txhim kho kev ua haujlwm, thiab muaj pwm siab tso tawm lub zog, ruaj khov qhov kub ntim, zoo siab kub thermal shock tsis kam, thiab lwm yam kom zoo dua. Cov. Tsis tas li ntawd, cov kua qaub-ua rau cov xau lossis cov xau xoos kho nrog silica sol tuaj yeem npaj cov khoom siv tshuaj uas tuaj yeem tiv taus cov kua qaub zoo, uas tuaj yeem tiv thaiv cov kua qaub thiab tiv thaiv kev ua haujlwm siab.
3. Xim
Txheej sab nrauv phab ntsa txheej ua los ntawm silica sol ua cov khoom ua yeeb yaj kiab tseem ceeb, hluavtaws emulsion (xws li styrene-acrylic emulsion, vinyl acetate resin emulsion) raws li cov khoom siv ua yeeb yaj kiab-tsim cov khoom ntxiv, ntxiv rau cov xim, ntawv sau thiab ntxiv rau, muaj qhov tshwj xeeb dej tsis kam, tiv taus hluav taws, rub tawm tsis kam, thiab cov pa phem kuj dhau los ua ib tug thawj coj hauv kev tsim qauv hauv xyoo tas los
Cov txheej txheej casting npaj los ntawm kev sib xyaw silica sol thiab refractory hmoov tuaj yeem tiv thaiv zoo dua hlau hmoov los ntawm melting thiab phaj ua puas thaum ua haujlwm steel cov hlau.
4. Kev lag luam Textile
Kho cov ntaub plaub nrog cov roj silica huab thiab roj roj tuaj yeem txhim kho spinnability ntawm ntaub plaub, txo qhov kawg ntawm kev tawg, tiv thaiv ya, thiab nce cov txiaj ntsig; siv nyob rau hauv lub teeb xov paj sizing daws, nws muaj peev xwm txhim kho lub adhesion ntawm slurry thiab yog yooj yim poob. , Ua kom lub sijhawm kom qhuav, thiab lwm yam.; ntxiv rau cov ntawv tuab tuaj yeem ua rau cov xov paj npleem tiv taus, ua cov ntaub kom tawv thiab qhuav, thiab tseem tuaj yeem tswj tau cov lus ntxig ntawm cov ntaub. Silica sol yog siv los ua ib qho kev sib ntxiv, uas tuaj yeem txhim kho qhov muaj peev xwm tiv thaiv kab mob fluff. Ntxiv rau, silica sol kuj tseem siv tau los ua tus neeg saib xyuas kev kho mob rau txhua hom ntaub, tsis hais txhua yam ntawm cov ntaub thiab cov xaws, los yog cov ntaub ua los ntawm nylon, viscose, acetate, polyester, polypropylene, thiab lwm yam, tom qab kev kho mob, Txhua yam muaj qhov zoo ntawm kev tu ncua, tsis xaub, kev txhim kho tsis zoo, ntxuav tsis kam, muaj kuab paug tsis kam thiab tiv thaiv zoo li qub.
5. Kev lag luam ntawv
Cellophane thiab yas zaj duab xis yog nquag npuaj rau lub caij ntuj sov. Yog tias kho nrog kev sib xyaw ntawm silica sol thiab monostearyl glyceride, nws tuaj yeem daws qhov txaus siab. Daim ntawv photosensitive yog kho nrog kev sib xyaw ntawm cov kua roj silica thiab cov kua ua kua, uas tuaj yeem ua rau saum npoo ntawm cov ntawv sib txuas nrog du, ua kom pom cov duab, thiab nce ntxiv rau kev sib txuam. Nws yog siv rau txheej txheej ua ntej ntawm daim phiaj, daim ntawv theej thiab offset luam ntawv, uas tuaj yeem ua rau daim ntawv saum npoo du, cov duab sib piv yog qhov pom tseeb, thiab qhov sib piv yog qhov zoo.
