Silica nag lossis daus yog ib txoj kev siv dav los tsim cov khoom zoo silicon dioxide. Vim nws cov khoom tshwj xeeb, xws li thaj chaw siab, qhov loj qhov pore ntim, thiab cov khoom siv kho tshuab zoo heev, silica yog siv rau ntau yam kev lag luam. Ib qho ntawm cov kev siv ntau tshaj plaws ntawm silica yog los ua tus neeg sawv cev thickening hauv cov xim.

Cov xim feem ntau yog siv los tiv thaiv thiab txhim kho kev zoo nkauj ntawm cov qauv, tsheb, thiab lwm yam khoom siv. Yuav kom ua tiav qhov kev ua tau zoo, cov viscosity ntawm cov xim yuav tsum siab txaus los tiv thaiv sagging thiab khiav tab sis tsis siab heev uas nws nyuaj rau thov. Nrog rau qhov sib ntxiv ntawm silica, cov viscosity ntawm cov xim tuaj yeem nce ntxiv kom ua tiav qhov tsim nyog tuab, thaum tseem tswj tau zoo txaus thiab cov yam ntxwv qib.

Silica yog zoo tagnrho raws li ib tug thickening neeg sawv cev rau cov xim vim nws particle loj thiab cov duab. Qhov me me me me ntawm silica kom ntseeg tau tias nws yuav kis tau tusyees thoob plaws hauv cov xim thaum tuav cov khoom ntws zoo. Tsis tas li ntawd, cov duab ntawm silica hais yog qhov muaj txiaj ntsig zoo, vim nws tso cai rau tsim ib lub network ntawm cov khoom uas tuaj yeem tuav cov xim hauv qhov chaw, tsis txhob sagging lossis khiav. Tsis tas li ntawd, thaj chaw siab ntawm silica muab ib qho zoo heev substrate rau kev sib txuas nrog lwm cov ntaub ntawv uas muaj nyob rau hauv cov xim.

Kev siv silica ua cov khoom ua kom tuab hauv cov xim muaj ntau yam txiaj ntsig. Ua ntej, nws ua kom cov xim yuav nyob hauv qhov chaw, pab tiv thaiv kev khiav thiab sagging. Qhov thib ob, qhov nce viscosity ntawm cov xim ua kom nws muaj cov yam ntxwv zoo. Thaum kawg, qhov sib ntxiv ntawm silica txhim kho cov khoom siv kho tshuab thiab tshuaj lom neeg ntawm cov xim, ua kom nws ruaj khov thiab tiv taus hnav thiab tsim kua muag.

Hauv kev xaus, siv silica nag lossis daus los ua tus neeg sawv cev thickening yog ib txoj hauv kev zoo los txhim kho cov khoom ntawm cov xim. Nws cov yam ntxwv tshwj xeeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov xim pleev xim, kom ntseeg tau tias nws yuav muaj cov dej ntws zoo tshaj plaws thiab qib qib thaum muab cov khoom tiav.
