Khoom Taw Qhia:

Gypsum yog cov khoom siv hauv tsev uas tsim cov micropores ntau hauv cov khoom tom qab solidification.Kev ua pa ua pa coj los ntawm nws qhov porosity ua rau gypsum ua lub luag haujlwm tseem ceeb hauv kev kho kom zoo nkauj sab hauv tsev niaj hnub.Qhov kev ua pa ua pa no tuaj yeem tswj cov av noo ntawm qhov chaw nyob thiab ua haujlwm, tsim kom muaj microclimate zoo.

Hauv cov khoom siv gypsum, txawm tias nws yog qib mortar, sib koom ua ke, putty, lossis gypsum raws li tus kheej-leveling, cellulose ether plays lub luag haujlwm tseem ceeb.Cov khoom tsim nyog cellulose ether tsis rhiab rau alkalinity ntawm gypsum thiab tuaj yeem ntub dej hauv ntau yam khoom gypsum yam tsis muaj agglomeration.Lawv tsis muaj kev cuam tshuam tsis zoo rau lub porosity ntawm solidified gypsum khoom, yog li ua kom cov pa ua haujlwm ntawm cov khoom gypsum.Lawv muaj qee yam kev cuam tshuam tab sis tsis cuam tshuam rau kev loj hlob ntawm gypsum crystals.Nrog rau qhov tsim nyog ntub adhesion, lawv ua kom muaj peev xwm sib txuas ntawm cov khoom siv rau lub substrate, zoo heev txhim kho kev tsim kho ntawm cov khoom siv gypsum, Ua kom yooj yim rau kev sib kis yam tsis ua raws li cov cuab yeej.

Qhov zoo ntawm kev siv cov tshuaj tsuag gypsum - lub teeb yuag plaster gypsum:

· Cracking kuj

· Tsis tuaj yeem tsim ib pab pawg

· Zoo sib xws

· Kev siv tau zoo

· Kev tsim kho du

· Kev tuav dej zoo

· Zoo flatness

· Tus nqi-zoo

Tam sim no, kev sim tsim cov tshuaj tsuag gypsum - lub teeb yuag plaster gypsum tau mus txog European cov qauv zoo.

Raws li cov lus ceeb toom, txau gypsum - lub teeb yuag plaster gypsum tau lees paub tias yog cov khoom siv hauv tsev nrog kev ua haujlwm zoo tshaj plaws ntawm peb txoj haujlwm loj vim muaj cov pa roj carbon tsawg tsawg thaum tsim khoom thiab siv, 100% rov ua dua cov ntaub ntawv cementitious hauv tsev, thiab kev lag luam thiab kev lag luam. cov txiaj ntsig kev noj qab haus huv.

Gypsum muaj ntau yam zoo.Nws tuaj yeem hloov cov phab ntsa sab hauv tsev pleev xim nrog cov cement, yuav luag tsis cuam tshuam los ntawm sab nraud cua sov thiab txias.Phab ntsa yuav tsis qhib nruas lossis tawg.Nyob rau hauv tib cheeb tsam ntawm phab ntsa, tus nqi ntawm gypsum siv yog ib nrab ntawm cov cement, uas yog nyob rau hauv ib tug tsawg-carbon ib puag ncig thiab nyob rau hauv txoj kab nrog tib neeg lub neej tam sim no lub tswv yim.
