Hydrochloric acid txheej txheem silica, raws li lub npe qhia, yog hais txog cov khoom amorphous silica tau los ntawm kev siv sodium silicate (feem ntau hu ua iav dej) cov khoom siv raw, reacting nrog hydrochloric acid rau acidification, thiab tom qab ntawd ua cov txheej txheem xws li neutralization, nag lossis daus, pom, ntxuav, ziab, thiab pulise pulise. Vim tias nws cov kauj ruam tseem ceeb cuam tshuam nrog tshuaj "precipitating" silica los ntawm cov tshuaj, nws tseem hu ua precipitated silica.
Cov txheej txheem no muab cov khoom tshwj xeeb physicochemical yam ntxwv: nws qhov loj me me feem ntau yog nyob rau hauv micron lossis sub-micron ntau yam, nrog cov porosity siab thiab tswj tau qhov chaw tshwj xeeb. Piv nrog rau fumed silica, uas yog npaj siv high -kub hydrolysis txheej txheem thiab yog kim, precipitated silica tuav ntau yam zoo heev thaum muaj ib tug tseem ceeb nqi kom zoo dua, ua rau nws loj - nplai daim ntawv thov nyob rau hauv industrial coatings, ntoo txheej, architectural txheej, thiab lwm yam teb. Nws yog tus nqi tiag tiag - txheej txheej zoo - qib silica.

Kev ua haujlwm ntawm Hydrochloric Silica hauv cov khoom siv:
Thaum hydrochloric acid txheej txheem silica raug tsim los tshwj xeeb rau cov txheej txheem txheej txheej, nws nthuav tawm ntau yam kev ua haujlwm zoo kawg li.
1. Kev ua haujlwm zoo mating
Qhov no yog qhov zoo tshaj plaws -paub muaj nuj nqi ntawm txheej - qib silica. Nws txoj hauv kev ua haujlwm yog: thaum cov xim zaj duab xis dries thiab kho, cov me me, nyuaj silica hais yog sib npaug ntawm cov xim zaj duab xis, tsim microscopic unevenness. Thaum lub teeb ci rau ntawm cov xim pleev xim, diffuse reflection tshwm sim, txo qhov gloss ntawm qhov chaw thiab ua rau cov nyhuv matte. Los ntawm kev xaiv cov khoom uas muaj qhov sib txawv ntawm qhov sib txawv thiab qhov loj me, cov txheej txheem engineers tuaj yeem tsim ntau yam gloss, los ntawm silky du mus rau qhov sib sib zog nqus matte, dav siv nyob rau hauv siab - cov rooj tog zaum kawg xim, cov xim zoo nkauj, thiab cov khoom siv topcoats.
2. Cov Thickening zoo heev thiab tiv thaiv -Txoj kev cuam tshuam
Qhov saum npoo ntawm precipitated silica hais yog nplua nuj nyob rau hauv silanol pawg, uas muaj peev xwm cuam tshuam nrog ib leeg los ntawm hydrogen daim ntawv cog lus, tsim ib tug tsis muaj zog tab sis zoo peb -sib txawv network qauv nyob rau hauv lub txheej txheej. Cov qauv no muab cov txheej txheem zoo thixotropy- uas yog, siab viscosity thaum so, tiv thaiv cov xim thiab hnyav muab tub lim sedimentation thiab agglomeration; thiab txo viscosity sai thaum raug shear quab yuam (xws li nplawm, txhuam, txau), ua kom yooj yim rau daim ntawv thov. Qhov no tsis tsuas yog ua kom muaj kev ruaj ntseg ntawm cov khoom thoob plaws hauv nws lub sijhawm khaws cia tab sis kuj ua tau zoo kom tsis txhob sagging thaum lub sij hawm thov, uas yog tshwj xeeb tshaj yog tseem ceeb hauv kev lag luam los tiv thaiv -corrosion coatings xav tau cov yeeb yaj kiab tshwj xeeb.
3. Qhov tseem ceeb Abrasion thiab Scratch Resistance
Silica nws tus kheej muaj siab Mohs hardness. Thaum cov khoom nyuaj no sib npaug sib npaug thiab ruaj khov rau hauv cov xim xim, lawv tuaj yeem txhim kho cov macroscopic hardness, mechanical zog, thiab abrasion resistance ntawm cov xim zaj duab xis. Qhov no yog qhov tseem ceeb ntawm kev ua tau zoo rau cov txheej txheem txheej txheej uas nquag hnav, xws li cov xim hauv pem teb, cov xim sab hauv rau tsheb thauj mus los (tsheb ciav hlau, dav hlau), thiab ntau yam kev tiv thaiv kev lag luam.
4. Zoo heev Anti-Caking thiab Anti-Adhesion Properties
Rau cov coil coatings, ntim txheej, los yog cov khoom pleev xim uas xav tau stacking thiab cia, xim zaj duab xis nto adhesion yog ib qho teeb meem. Cov micro-protrusions tsim los ntawm txheej txheej- qib silica ntawm cov xim zaj duab xis saum npoo tuaj yeem txo qhov kev sib cuag tiag tiag ntawm cov txheej txheej, yog li txo lawv cov adhesion nyiam thiab ua kom cov khoom zoo thiab kev nyab xeeb ntawm kev thauj mus los.
