Dab tsi yog silica xuab zeb?
Silica xuab zeb, tseem hu ua quartz xuab zeb, xuab zeb dawb los yog muaj xuab zeb, yog tsim los ntawm ob lub ntsiab tseem ceeb: silica thiab oxygen. Tshwj xeeb, silica xuab zeb yog tsim los ntawm silicon dioxide (SiO2).
Daim ntawv feem ntau ntawm SiO2 yog quartz - ib qho tshuaj inert thiab kuj nyuaj ntxhia. SiO2 muaj qhov nyuaj ntawm 7 tawm ntawm 10 ntawm Mohs nplai, ua rau nws zoo tagnrho rau kev siv lim tawm thiab sandblasting.
Txawm hais tias quartz feem ntau yog dawb lossis tsis muaj xim, nws tuaj yeem tuaj yeem ua ntau yam ntxoov ntxoo. Cov xim ntawm txhua cov xuab zeb tso nyiaj nyob ntawm ntau yam ntawm cov ntxhia thiab cov pob zeb tawg uas ua rau cov peev txheej.
Yuav kom txiav txim siab silica xuab zeb, cov khoom yuav tsum muaj tsawg kawg yog 95% SiO2 thiab tsawg dua 0.6% hlau oxide. Yog tias cov xuab zeb tsis ua raws li tus qauv no, nws yuav raug suav hais tias yog dab tsi feem ntau hu ua "ib txwm" xuab zeb.
Dab tsi yog qhov txawv ntawmsilica xuab zebthiab tej xuab zeb?
Cov xuab zeb tsis tu ncua, tseem hu ua feldspathic xuab zeb, xuab zeb xim av lossis xuab zeb siv, ib txwm muaj qee cov silica, tab sis tsawg dua 95%. Piv txwv li, cov xuab zeb xim av ib txwm siv hauv cov ntawv thov pob zeb yuav muaj txog li 80% SiO2, nrog rau ntau cov hlau, carbonates, poov tshuaj, thiab lwm yam kab / minerals.
Cov "impurities" no ua rau cov xuab zeb tsis tu ncua ntau cov tshuaj muaj zog thiab feem ntau tsaus dua li cov xuab zeb silica. Cov xuab zeb uas tsis yog silica (cov xuab zeb zoo ib yam) tuaj yeem pom nyob rau hauv ntau qhov ntxoov ntxoo dawb, liab dawb, ntsuab thiab dub, nyob ntawm seb lub geological pleev thiab thaj chaw ntawm cov xuab zeb tso nyiaj.
Dab tsi yog silica xuab zeb siv rau?
Silica xuab zeb muaj ntau yam kev lag luam thiab kev lag luam siv, los ntawm cov chav golf mus rau iav tsim. Silica xuab zeb yog cov khoom lag luam thiab cov neeg siv khoom siv dav siv thoob plaws hauv North America.
Yuav siv li cas silica xuab zeb nyob ntawm lub cev, tshuaj thiab cov khoom siv xws li particle loj, zoo li, xim, qauv thiab kev faib tawm, nrog rau refractoriness, lub zog thiab ruaj khov. Cov khoom no tuaj yeem sib txawv nyob ntawm seb cov ntxhia ua tiav li cas tom qab nws tau mined.
Nov yog xya qhov kev siv rau silica xuab zeb:
1. Cov chaw ntaus golf thiab chaw ua si
Silica xuab zeb yog siv nyob rau hauv golf chav bunkers thiab muab cov zaub ntsuab, nrog rau ntawm tej yam ntuj tso thiab hluavtaws ua si teb. Thaum koj ua si kaum yim, cov xuab zeb ntxiab koj pom koj tus kheej tas li daig hauv feem ntau yog cov xuab zeb silica. Vim tias nws muaj peev xwm los txhawb cov dej ntws thiab kev loj hlob ntawm cov nroj tsuag ntuj, nws kuj tuaj yeem siv los tswj cov zaub ntsuab thiab kev ncaj ncees. Rau turf teb, silica xuab zeb yog siv los ua cov txheej txheem tseem ceeb ntawm cov lim dej tsis huv.
2. Muaj abrasives
Silica xuab zeb feem ntau yog siv los ua cov ntxhia abrasive hauv kev lag luam sandblasting. Txawm hais tias sandblasting nrog silica xuab zeb tsim cov plua plav phom sij, qhov kis tau yooj yim zam tau los ntawm kev ua raws li PPE (cov khoom siv tiv thaiv tus kheej) cov lus qhia thiab / lossis txheej cov xuab zeb nrog cov tshuaj tsim los tswj cov plua plav.
3. Kev lim dej
Ib qho ntawm feem ntau siv rau silica xuab zeb yog nyob rau hauv dej pom, txawm tias kho cov dej zoo los yog lim dej kais dej. Vim nws cov duab thiab qhov loj me, silica xuab zeb yog lub txaj lim zoo uas tsis tu ncua tshem tawm cov kab mob hauv dej. Tsis tas li ntawd, nws tsis degrade thaum raug rau cov tshuaj acidic.
4. Kev tsim iav
Silica xuab zeb yog cov khoom tseem ceeb hauv kev tsim khoom iav, thiab qhov tseeb, silica yog ib qho tseem ceeb ntawm cov khoom siv iav xws li lub qhov rais mus rau lub raj mis npias. Lub purity ntawm silica xuab zeb siv los txiav txim cov xim, lub zog thiab clarity ntawm cov khoom kawg.
5. Xim thiab Txheej
Silica xuab zeb yog siv nyob rau hauv cov xim thiab coatings los txhim kho tag nrho cov tsos thiab durability ntawm cov xim. Silica fillers txhim kho lub teeb thiab stain tsis kam ntawm cov xim, thiab vim yog cov roj-absorbing ntawm silica xuab zeb, nws tsim cov txheej ruaj khov uas muaj cov xim nplua nuj thiab tiv taus hnav thiab tsim kua muag.
6. Ceramics thiab cov khoom siv refractory
Silica yog ib qho tseem ceeb ntawm kev tsim kho thiab glazes ntawm txhua hom ceramics, xws li tableware, pem teb vuas, phab ntsa vuas, thiab lwm yam. Silica yog cov pob txha pob txha ntawm cov khoom siv ceramic, pab tswj kev nthuav dav thiab kev cog lus, kom ntseeg tau tias cov khoom siv ceramics kom qhuav, thiab ua kom tag nrho cov khoom siv ceramic.
7. Cov khoom siv hauv tsev
Silica xuab zeb (feem ntau hu ua cov xuab zeb ua haujlwm thaum siv rau lub hom phiaj no) yog ib qho tseem ceeb ntawm cov khoom siv tsim kho. Pem teb, mortar, cement, shingles, asphalt thiab lwm yam ntaub ntawv siv silica los ua kom durability thiab structural kev ncaj ncees. Silica feem ntau yog siv los ua caulk lossis sealant vim nws tsis kam rau huab cua, abrasion thiab corrosion.
Silica xuab zeb muaj ntau yam kev siv nyob rau hauv lub neej txhua hnub nyob rau hauv ntau yam kev lag luam.
