Rau cov neeg pob zeb, hais txog limestone tsis yog txawv txawv, nws lub ntsiab tseem ceeb yog calcium carbonate CaCO3, txiv qaub thiab limestone yog siv dav hauv cov khoom siv hauv tsev thiab cov khoom siv raw khoom.Thiab hauv lub neej, qhov tseeb, peb tuaj yeem pom limestone nyob txhua qhov chaw, tej zaum peb tau ntev lawm. siv rau nws, tab sis tsis quav ntsej nws lub luag haujlwm, ntawm no peb rov ua kom lub ntsej muag ci ntsa iab ntawm limestone, cia's tau saib ntau yam kev siv ntawm limestone.
Calcium carbonate tuaj yeem ua tiav ncaj qha rau hauv pob zeb thiab raug rho tawm mus rau hauv quicklime.Qhov tseem ceeb ntawm quicklime yog CaO, uas feem ntau loj, dawb huv, thiab lub teeb grey los yog lub teeb daj thaum muaj impurities.Quicklime absorbs noo noo los yog ntxiv dej los ua hydrated txiv qaub, tseem hu ua hydrated txiv qaub, nws lub ntsiab tivthaiv yog Ca (OH) 2.
Feem ntau hais lus, limestone raug kub hnyiab los tsim cov hmoov nplej siab calcium carbonate, siv los ua cov roj hmab, yas, ntawv, tshuaj txhuam hniav, tshuaj pleev ib ce, thiab lwm yam.
Alkali txiv qaub ua nrog caustic soda thiab siv los ua ib qho nqus ntawm carbon dioxide; Quicklime yog siv los ua desiccant thiab tshuaj tua kab mob.
Tsis tas li ntawd, ua ke nrog nws cov khoom siv tshuaj, quicklime kuj muaj kev siv hauv kev lag luam: nrog quicklime tuaj yeem npaj cov txiv qaub sulfur sib tov, Bordeaux kua thiab lwm yam kev ua liaj ua teb.
Tshuaj; Siv slaked txiv qaub nyob rau hauv cov av tuaj yeem neutralize av acidity, txhim kho av qauv, muab calcium xav tau los ntawm cov nroj tsuag, thiab txhawb kev loj hlob ntawm cov qoob loo.
Txhuam tsob ntoo nrog txiv qaub pulp los tiv thaiv tsob ntoo zoo.
Tsis tas li ntawd, hnyav calcium carbonate ua ncaj qha los ntawm limestone tom qab coarse crushing thiab crushing yuav muab faib mus rau hauv nyias hmoov (95%) vim hais tias ntawm txawv degree ntawm crushing.
200 mesh), ob zaug ya hmoov (99% txog 325 mesh), triple yoov hmoov (99.9% txog 325 mesh), plaub ya hmoov (99.95% txog 400 mesh, txhua
Muaj lub hom phiaj.Single yoov hmoov tuaj yeem siv los tsim cov calcium chloride anhydrous, yog cov khoom siv raw ntawm sodium dichromate ntau lawm; Shuangfei hmoov yog tsim cov anhydrous calcium chloride thiab iav, thiab lwm yam.
Cov khoom siv dawb rau cov khoom siv raw, roj hmab thiab xim, thiab cov khoom siv hauv tsev; Sanfei hmoov: siv los ua cov khoom siv rau cov yas, xim pleev xim, xim, plywood thiab xim
Khoom siv; Nws yog siv los ua cov khoom siv rau insulating txheej ntawm hluav taws xob hlau, roj hmab molding khoom thiab asphalt xav.
Raws li ib qho tseem ceeb ntawm limestone, calcium carbonate yog ib qho tseem ceeb hauv tsev cov khoom.Dawb thiab ntshiab calcium carbonate pob zeb hu ua dawb marble thiab feem ntau yog siv los kho kom zoo nkauj.
Cov pob zeb pob zeb lossis cov khoom siv tes ua, cov chaw zoo nkauj; Rau impurities muaj cov qauv zoo nkauj ntawm calcium carbonate marble, siv los ua cov phab ntsa thiab phab ntsa veneer lossis khw
Teeb tsa hauv av; Compact calcium carbonate pob zeb (limestone) kuj tuaj yeem siv ncaj qha rau lub tsev, tab sis kev siv lub ntsiab ntawm limestone yog tsim cov cement.
Yog li, feem ntau, limestone yog ntau tshaj li kev siv pob zeb yooj yim, kev lag luam, kev lag luam thiab lwm yam yog qhov tseem ceeb, tsis tuaj yeem kwv yees nws!
