Quartz xuab zeb: cov uas thiab ntau lawm

Silica xuab zeb yog ib cov khoom uas muaj ib tug tej yam ntuj tso keeb kwm thiab txawv yam ntxwv xws li tshuaj inertness, ua hauj degradation, durability, thiab muaj peev xwm sorbing. Feem ntau cov feem ntau nws yog siv nyob rau hauv lub pom ntawm cov roj thiab dej, rau zus tau tej cov kev tsim kho thiab finishing cov ntaub ntawv, raws li tau zoo raws li tsim lub pas dej. Tam sim no txhua yam nyob rau hauv kom meej.

Pom muaj peev xwm

Quartz xuab zeb lim yog siv ntau tshaj li lwm yam natural khoom. Lub fact tias nws porosity piv rau pa crushed xuab zeb yog ntau dua. Qhov no, nyob rau hauv lem, muab nws ua ib siab av tuav peev xwm thiab sorption muaj peev xwm, ua cov dej tshwm sim txawm hais xws li manganese thiab yaj hlau. Vim li no, quartz xuab zeb rau ua luam dej pas dej ua ke, dag pas dej los yog pas dej, los yog es, mus rau lawv cov pom tshuab, siv luag yeej ib txwm. Pom zoo feem nyob rau hauv cov neeg mob yog nyob rau hauv lub chav los ntawm 0.4 mus 6.0 millimeters.

Siv nyob rau hauv kev tsim kho

Thoob plaws siv ntawm quartz xuab zeb nyob rau hauv ib tug kev tsim kho hauv cheeb tsam, nyob rau hauv particular thaum tsim polyurethane thiab epoxy flooring. Nyob rau hauv cov ntaub ntawv no, nws yuav tsum tau muaj ib coarse feem. Siv ntawm no cov ntaub ntawv uas nyob rau hauv zus tau tej cov plasters thiab tsev hmoov sib tov yog vim nws cov high tshuaj lom neeg kuj, neeg kho tshuab kuj mus crushing thiab puas, raws li zoo raws li xim stability. Nplua zoo suited rau Sandblasting txheej txheem iav, pob zeb ua thiab hlau. Cov khoom kuj yog siv nyob rau hauv qhov siv thiab ua cov khoom cua pob zeb.

lwm yam hauj lwm

Tag nrho cov saum toj no siv lub silica xuab zeb yuav tsis tag. Nws yog feem ntau siv nyob rau hauv kev tsim kho ntawm kua systems, greenhouses, dej zoo drilling, raws li pub rau nqaij qaib, li zoo li ib tug tub lim rau hluav taws xob insulators thiab waterproof khoom. Nyob rau hauv xyoo tsis ntev los no, qhov no zoo ntawm cov xuab zeb yuav tsum nyob rau hauv cov thoob dej yug ntses thiab toj roob hauv pes tsim.

ntau lawm

Yog haum ntau tej yam ntuj tso khoom, quartz xuab zeb ntawm chaw txua txiag zeb nyob rau hauv cov ntxaij lim dej, siv cov ntaub ntawv los yog lwm yam uas duav txhua yam ntawm daim ntawv thov yog tsis ncaj qha ntaus. Qhov no yuav ua feem ntau ntaus nqi mus rau nuance hais tias nws yog tsim nyog los xaiv ib tug haum feem daws ntau yam kev pab raws qib. Nyob rau hauv tas li ntawd, hauv cov xuab zeb feem ntau muaj ib tug loj npaum li cas los ntawm ntau yam impurities, nyob rau hauv kev twb kev txuas nrog cov uas cov ntaub ntawv uas yuav tsum tau pre-kev kho mob, uas yog ib tug theej txoj kev.

Nta ntawm daim ntawv thov

Cov tsos ntawm npaj los siv quartz xuab zeb precedes ob peb ua hauj lwm, xws li tu ntaub ntawv los ntawm impurities, kom qhuav, fractionation, ntau npaum thiab ntim. Nyob rau hauv cov ntaub ntawv no, nyob rau hauv txhua rooj plaub, ib tug yuav tsum tsis txhob underestimate qhov tseem ceeb ntawm cov feem ntawm cov khoom no, vim hais tias nyob rau hauv ib co lag luam (piv txwv li, thaum lub sij hawm siv thiab ua cov iav), nws plays ib tug tseem ceeb luag hauj lwm. Ib qho tseem ceeb txog kev paub, uas yog yus muaj los ntawm quartz xuab zeb, yog tus tsis muaj ib yam tshuaj cov tshuaj tiv thaiv. Qhov no siv tau, saum toj no tag nrho, cov kev siv, vim hais tias tom qab lub solidification ntawm MAAs cug los ua vaj tse tej zaum yuav tshwm sim undesirable txim.
