Quartz xuab zeb yog cov khoom siv los ntawm ntuj tsim thiab muaj cov yam ntxwv xws li tshuaj lom neeg inertness, tawg tsis kam, lub zog, thiab muaj peev xwm sorption. Feem ntau nws yog siv rau hauv kev pom cov khoom siv roj thiab dej, rau kev tsim cov khoom tiav thiab cov khoom siv hauv tsev, nrog rau kev tsim cov pas dej da dej. Tam sim no hais txog txhua yam hauv kev nthuav dav ntxiv.
lim peev
Quartz xuab zeb rau cov lim dej yog siv ntau dua li lwm yam khoom siv ntuj. Qhov tseeb yog tias nws qhov porosity ntau dua piv rau cov xuab zeb zoo tib yam crushed. Qhov no, nyob rau hauv lem, muab nws nrog lub siab tshaj plaws av tuav peev thiab sorption muaj peev xwm, vim hais tias txawm hais tias xws li manganese thiab yaj hlau raug tshem tawm ntawm dej. Rau tib lub laj thawj, quartz xuab zeb rau lub pas dej, cov pas dej cuav lossis pas dej, los yog, rau lawv qhov kev pom, yuav luag txhua zaus siv. Cov feem ntau pom zoo nyob rau hauv cov ntaub ntawv no muaj li ntawm 0.4 mus rau 6.0 millimeters.
siv kev tsim kho
Daim ntawv thov dav ntawm quartz xuab zeb muaj nyob rau hauvkev tsim kho kev lag luam, tshwj xeeb tshaj yog thaum tsim polyurethane thiab epoxy pem teb. Hauv qhov no, nws yuav tsum muaj ib qho ntxhib-grained feem. Kev siv cov khoom siv no hauv kev tsim cov plasters thiab lub tsev sib tov yog vim nws cov tshuaj lom neeg muaj zog, kev ua haujlwm tsis zoo rau crushing thiab puas, nrog rau xim stability. Fine fractions yog zoo haum rau sandblasting thaum ua iav, pob zeb thiab hlau. Cov khoom siv kuj tseem siv los tsim cov pob zeb dag.
Lwm thaj chaw
Kev siv quartz xuab zeb tsis txwv rau tag nrho cov saum toj no. Nws yog feem ntau siv nyob rau hauv kev tsim kho ntawm lub tsev xog paj tso dej, drilling cov dej qhov dej, raws li ib tug pub rau nqaij qaib, thiab raws li ib tug muab tub lim rau hluav taws xob insulators thiab waterproofing khoom. Tsis ntev los no, hom xuab zeb no tuaj yeem pom nyob rau hauv thoob dej yug ntses thiab toj roob hauv pes tsim.
Production
Ua cov khoom siv ntuj tsim, quartz xuab zeb tsis ncaj qha nkag mus rau cov lim dej, cov khoom siv hauv tsev lossis lwm yam kev siv ncaj qha los ntawm chaw txua txiag zeb. Qhov no tuaj yeem piav qhia feem ntau los ntawm qhov nuance tias txhawm rau daws qee yam teeb meem nws yog qhov tsim nyog los xaiv ib feem tsim nyog. Tsis tas li ntawd, xuab zeb feem ntau muaj ntau ntau yam impurities, thiab yog li cov khoom yuav tsum tau kho ua ntej, uas yog ib qho nyuaj heev.
Daim ntawv thov nta
Cov tsos ntawm cov quartz xuab zeb tau npaj ua ntej los ntawm ntau qhov kev ua haujlwm ib zaug, suav nrog kev ntxuav cov ntaub ntawv nyoos los ntawm impurities, ziab, fractionation, ntau npaum li cas thiab ntim. Nyob rau tib lub sijhawm, qhov tseem ceeb ntawm feem ntawm cov khoom siv no yuav tsum tsis txhob kwv yees, vim tias hauv qee qhov kev lag luam (piv txwv li, hauv kev tsim cov iav) nws ua lub luag haujlwm tseem ceeb. Lwm qhov kev ntsuas tseem ceeb uas qhia txog quartz xuab zeb yog qhov tsis muaj tshuaj lom neeg hauv nws. Qhov no siv, ua ntej ntawm tag nrho cov, rau kev tsim kho, vim hais tias tom qab hardening ntawm cement mortars los yog pob zeb, undesirable txim yuav tshwm sim.
Pom zoo:
Cov khoom siv xoob (xuab zeb, pob zeb crushed): ntau lawm thiab muag
Sand thiab crushed pob zeb yog siv los ua lub hauv paus rau ntau lub tsev thiab kev tsim kho kom zoo nkauj, nrog rau cov khoom sib xyaw ua ke
Hom xuab zeb, lawv cov yam ntxwv, rho tawm thiab siv
Hnub no, yuav luag txhua hom xuab zeb yog siv los ntawm tus txiv neej hauv ntau yam haujlwm thiab kev lag luam. River xuab zeb yog lub tsev sib tov uas tau muab rho tawm los ntawm tus dej hauv qab. Cov khoom siv no muaj ntau qhov kev ua kom huv, uas yog vim li cas tsis muaj pob zeb me me, av nplaum cov ntsiab lus impurities thiab txawv teb chaws inclusions nyob rau hauv cov qauv
Raw khoom rau kev lag luam - dawb quartz xuab zeb
Yuav ua li cas tej txuj ci tseem ceeb uas tsis tau npaj rau lub ntiaj teb rau txiv neej! Ntawm no, piv txwv li, yog ib qho amazing pom - xuab zeb dawb. Los ntawm qhov deb, koj yuav tsis nkag siab tam sim ntawd: nws puas yog snowdrifts nyob rau hauv nruab nrab ntawm lub caij ntuj sov, los yog roob ntawm granulated qab zib, los yog tej zaum lub rooj ntsev los yog lwm yam tshuaj?
Fraction yog qhov tseem ceeb thaum xaiv cov pob zeb crushed thiab xuab zeb rau kev tsim kho
Yog tsis muaj xuab zeb thiab pob zeb, nws tsis tuaj yeem tsim cov khoom siv hauv tsev ntau tshaj plaws - pob zeb, thiab ua haujlwm ua haujlwm. Nyob ntawm cov kev xav tau, cov seem xav tau raug xaiv, uas yog muab los ntawm cov qauv hauv tsev. Yuav ua li cas xaiv txoj cai, xav txog hauv qab no
Pob zeb diamond hmoov: ntau lawm, GOST, daim ntawv thov. pob zeb diamond cuab yeej
Hnub no, pob zeb diamond hmoov tau dav siv. Kev siv lub ntsiab ntawm cov khoom siv raw no yog kev tsim cov cuab yeej rau kev ua cov pob zeb. Tsis tas li ntawd, nws tsim nyog sau cia tias kev txhim kho thev naus laus zis tau ua kom tau txais cov hmoov tsis tsuas yog los ntawm cov khoom ntuj tsim, tab sis kuj los ntawm cov khoom siv hluavtaws
