Maas tsis yog cov khoom siv ntuj. Cov txheej txheem ntawm nws cov ntau lawm nws kim heev thiab laborious, tab sis nws tsim nyog nws: cov zis yog ib qho ntawm cov tsev nyiam tuaj, siv ntawm nws tus kheej thiab ua cov khoom siv ntawm lwm cov khoom sib xyaw, piv txwv li, qhob.
Cov Lus Qhia

Yog tias koj txiav txim siab pib tsim cov cement, tom qab ntawd nco ntsoov tias nws yog qhov zoo dua rau kev cog ntoo cog ze ntawm qhov chaw rho tawm ntawm cov ntaub ntawv raw khoom tsim nyog rau nws kev tsim khoom. Kev ua cov xis mas suav nrog ob theem: thawj yog kev tsim khoom ntawm clinker, qhov thib ob yog coj tus clinker mus rau ib lub xeev hmoov nrog ntxiv ntawm gypsum lossis lwm yam. Nws yuav tsum tau yug hauv siab tias qhov kim tshaj plaws yog thawj theem - nws suav txog kwv yees li 70% ntawm tus nqi ntawm cov xis mas.

Hauv thawj theem, koj yuav tsum tau txais cov khoom raw. Kev txhim kho ntawm cov pob zeb lim dej xav tau rau kev tsim cov cement yog nqa tawm los ntawm kev rhuav tshem, i.e. ib feem ntawm lub pob zeb yog "tshem tawm", pom ib txheej ntawm pob zeb daj-ntsuab limestone. Tom qab ntawd, cov khoom siv no raug xa nrog ib qho khoom siv rau kev rhuav tshem cov khoom, ziab, sib tsoo thiab nws nrog lwm cov khoom sib xyaw. Tom qab ntawd lub txiaj ntsig sib tov yog tua. Qhov no yog li cas clinker tau ua.

Qhov thib ob theem ntawm kev ua cov cement tseem muaj ntau theem. Nws suav nrog crushing clinker, ziab ziab pob zeb hauv av, tsoo gypsum, sib xyaw clinker nrog gypsum thiab cov ntxhia ntxiv. Txawm li cas los xij, nco ntsoov tias cov ntaub ntawv nyoos tsis yog ib txwm zoo ib yam, lawv cov khoom siv lub cev (lub cev ntom nti, noo noo, thiab lwm yam) sib txawv. Hauv qhov no, muaj ntau txoj kev sib txawv rau txhua hom khoom siv raw khoom. Qhov no tso cai rau koj kom ua tiav kev sib tsoo zoo thiab ua tiav kev sib xyaw ntawm cov khoom.

Koj tuaj yeem tsim cov cement raws li ib ntawm peb txoj kev: ntub, qhuav, thiab kev sib xyaw. Thawj txoj kev yog siv rau hauv kev tsim cov khoom siv los ntawm xaum av, av nplaum thiab hlau uas muaj cov quav ntxiv. Txoj kev no yog hu ua ntub dej vim tias qhov sib xyaw ntawm cov cheebtsam tshwm sim hauv qhov nruab nrab aqueous. Ntawm qhov tawm mus, aqueous kev ncua yog tau txais - sludge, uas nkag mus rau hauv lub ncu rau hluav taws. Tus clinker tsim nyob rau hauv qhov cub ua kom sov, tom qab txias, yog hauv av ua hmoov - maas. Nrog rau txoj kev qhuav ntawm cov khoom lag luam, txhua tus txheej txheem tau qhuav, thiab nrog txoj kev sib koom ua ke, kev sib koom ua ke ntawm ob txoj hauv kev dhau los. Nco ntsoov tias rau txhua txoj kev tsim khoom muaj cov khoom tsim tshwj xeeb thiab sib lawv liag ua haujlwm, nyob ntawm yam thev naus laus zis.
