Cov neeg siv tsis txaus siab: Cov Cement tsis tuaj yeem ziab Tom qab ntxiv koj MHEC lossis HPMC. — 11 Peb. 2023
Hauv ntiaj teb kev tsim kho thiab cov khoom siv hauv tsev, cement tuav ib qho chaw tseem ceeb. Nws ua raws li tus neeg sawv cev khi, muab lub zog thiab ruaj khov rau cov qauv. Txawm li cas los xij, tsis ntev los no, muaj ntau tus neeg siv kev tsis txaus siab txog cov cement tsis ziab kom zoo tom qab siv MHEC (Methyl Hydroxyethyl Cellulose), ib qho tshuaj ntxiv siv hauv kev tsim cov cement.
MHEC tau siv dav hauv kev tsim kho kev lag luam los txhim kho cov khoom ntawm cov cement. Nws ua raws li tus neeg saib xyuas dej, txhim kho kev ua haujlwm thiab txo cov dej xav tau. Cov tshuaj ntxiv no paub txog nws lub peev xwm los ua kom cov nplaum nplaum ntawm cov cement, ua rau nws yog ib qho tseem ceeb hauv kev tsim cov khoom siv ntau yam.
Txawm li cas los xij, qee cov neeg siv khoom tau tshaj tawm tias cov cement, txawm tias tom qab ncua sij hawm, tsis qhuav txaus. Qhov teeb meem no tau ua rau muaj kev txhawj xeeb tsis yog ntawm cov neeg siv khoom nkaus xwb tab sis kuj ntawm cov tuam txhab tsim kho, ua rau qeeb thiab cov nqi ntxiv. Nws dhau los ua qhov tseem ceeb rau kev txheeb xyuas qhov ua tau tom qab cov neeg siv khoom tsis txaus siab no thiab nrhiav kev daws teeb meem los kho lawv.
Ib qho laj thawj zoo rau cov cement tsis ziab tuaj yeem yog qhov tsis raug ntawm MHEC. Tus nqi pes tsawg ntawm cov tshuaj ntxiv no yuav tsum tau ua tib zoo xam kom ntseeg tau tias cov khoom xav tau ntawm cov cement sib tov. Yog tias qhov ntau npaum li cas tshaj qhov kev txwv, nws tuaj yeem cuam tshuam cov txheej txheem hydration thiab cuam tshuam qhov ziab ntawm cov cement. Yog li ntawd, nws yog ib qho tseem ceeb rau cov tuam txhab tsim khoom thiab cov neeg cog lus ua raws li cov lus qhia tau teev tseg thiab siv cov tshuaj tsim nyog ntawm MHEC.
Tsis tas li ntawd, qhov zoo ntawm MHEC siv hauv kev tsim cov cement plays lub luag haujlwm tseem ceeb hauv cov txheej txheem ziab. Cov khoom siv tsis zoo lossis tsis huv yuav muaj cov kab mob uas cuam tshuam rau cov tshuaj lom neeg uas tsim nyog rau cov cement kom kho kom zoo. Cov neeg tsim khoom yuav tsum ua qhov tseem ceeb ntawm MHEC los ntawm cov neeg muab khoom lag luam uas ntseeg siab thiab muaj koob npe los txo cov teeb meem zoo li no.
Lwm qhov tseem ceeb uas yuav tsum tau xav txog yog qhov chaw ib puag ncig thaum lub sijhawm thiab tom qab siv cement. Cov txheej txheem ziab ntawm cov cement hnyav heev nyob ntawm qhov kub thiab av noo. Kev kub siab lossis qis qis, nrog rau cov av noo ntau dhau, tuaj yeem cuam tshuam qhov ziab ntawm cov cement, txawm tias muaj MHEC. Cov neeg siv khoom yuav tsum tau ceeb toom txog qhov zoo ib puag ncig uas yuav tsum tau ua kom cov cement kom qhuav kom zoo.
Ntxiv mus, kev sib xyaw tsis txaus ntawm MHEC nrog cov cement sib tov kuj tuaj yeem ua rau kom qhuav tsis txaus. Cov additive yuav tsum tau sib npaug sib npaug thoob plaws hauv cov cement kom ntseeg tau tias kev ua haujlwm zoo ib yam. Cov neeg tsim khoom yuav tsum xav txog kev nqis peev hauv cov cuab yeej sib xyaw kom ua tiav cov homogeneous sib xyaw.
Txhawm rau hais txog cov neeg siv khoom tsis txaus siab txog cov cement tsis ziab kom txaus, nws yog ib qho tseem ceeb rau cov tuam txhab lag luam kom ua tiav kev tshawb fawb thiab tshuaj xyuas. Lawv yuav tsum koom tes nrog cov kws tshaj lij thiab cov kws tshaj lij hauv kev ua haujlwm txhawm rau txheeb xyuas cov hauv paus hauv paus ntawm qhov teeb meem thiab siv cov kev txhim kho tsim nyog. Tsis tas li ntawd, cov tuam txhab tsim khoom yuav tsum txhim kho kev sib txuas lus nrog cov neeg siv khoom thiab muab cov lus qhia meej thiab cov lus qhia kom ntseeg tau tias kev siv MHEC kom raug.
Hauv kev xaus, cov neeg siv khoom tsis txaus siab tsis ntev los no hais txog cov cement tsis ziab tom qab siv MHEC hais txog qhov xav tau rau cov tuam txhab tsim khoom thiab cov tuam txhab tsim kho kom rov ntsuam xyuas lawv cov txheej txheem ntau lawm. Kev noj zaub mov kom zoo, cov khoom siv zoo tshaj plaws, cov kev mob zoo ib puag ncig, thiab kev sib xyaw ua ke yog qhov tseem ceeb uas yuav tsum tau txiav txim siab los kho qhov teeb meem no. Los ntawm kev hais txog cov kev txhawj xeeb no, cov tuam txhab tsim khoom tuaj yeem txhim kho cov neeg siv khoom txaus siab, txhim kho cov txheej txheem tsim kho, thiab ua kom tiav kev kho thiab ziab ntawm cov cement.
Ua tsaug rau koj qhov kev txhawb nqa JINJI CHEMICAL!
