qhia
Qhuav mortar yog siv nyob rau hauv ntau yam kev tsim kho daim ntawv thov xws li masonry, rwb thaiv tsev thiab flooring.Nyob rau hauv xyoo tas los no, hydroxypropylmethylcellulose (HPMC) tau dhau los ua ib qho khoom siv feem ntau hauv cov khib nyiab qhuav.HPMC yog ntau yam polymer uas tuaj yeem muab ntxiv rau cov tshuaj khib nyiab qhuav los txhim kho adhesion, dej tuav thiab ua haujlwm.Tsab ntawv xov xwm no yuav tshawb txog cov txiaj ntsig ntawm kev siv HPMC hauv mortar qhuav thiab vim li cas nws thiaj li yog thawj qhov kev xaiv ntawm cov neeg tsim khoom thiab cov neeg cog lus.
HPMCs yog dab tsi?
Hydroxypropyl methylcellulose yog cellulose derivative uas ua los ntawm cov ntaub ntawv ntuj polymer.HPMC yog dej soluble heev thiab tsim cov kua dej ntshiab thaum tov nrog dej txias.Cov polymer yog tsis muaj tshuaj lom thiab muaj kev nyab xeeb rau kev siv hauv cov khoom noj thiab tshuaj.HPMC tsis muaj ntxhiab, tsis qab, thiab muaj kev ruaj ntseg zoo heev.
Txhim kho adhesion
Ib qho txiaj ntsig tseem ceeb ntawm kev siv HPMC hauv mortar qhuav yog nws lub peev xwm los txhim kho adhesion.Adhesion yog hais txog lub peev xwm ntawm cov tshuaj khib kom ua raws li qhov chaw nws tau pleev xim rau.HPMC hloov qhov nro ntawm lub mortar, yog li txhim kho nws cov adhesion rau ntau yam substrates xws li pob zeb, masonry, ntoo thiab hlau.HPMC tsim ib txheej tiv thaiv nyob ib ncig ntawm cov cement hais nyob rau hauv lub mortar, txo lub sij hawm ntawm cov khoom sib cais los ntawm substrate.
tuav dej
HPMC nce lub peev xwm khaws dej ntawm cov mortar, txhim kho kev ua haujlwm thiab tso cai rau cov neeg tsim khoom siv nws ntev dua.Los ntawm stabilizing cov ntsiab lus dej ntawm cov tshuaj khib nyiab qhuav, HPMC tuaj yeem txhawb nqa cov txheej txheem dej kom zoo dua qub, ua rau muaj zog dua, ruaj khov khoom kawg.Txhim kho kev tuav dej kuj tseem ua kom zoo sib xws thiab txuag sijhawm rau cov neeg tsim khoom thiab cov neeg cog lus.
Kev ua tau zoo
Kev ua haujlwm tau hais txog qhov yooj yim uas cov tshuaj khib nyiab qhuav tuaj yeem tsim thiab ua kom zoo raws li cov kev xav tau tshwj xeeb.HPMC txhim kho kev ua haujlwm ntawm cov khoom sib xyaw qhuav thiab ua kom muaj kev sib koom ua ke rau hauv mortar, ua kom yooj yim dua, zoo dua kev tsim kho.HPMC hloov qhov nro ntawm lub mortar, ua rau thaj chaw sib cuag ntawm lub mortar thiab nws qhov chaw tsim kho, yog li txhim kho kev ua haujlwm.Tsis tas li ntawd, HPMC tsim ib zaj duab xis nyias nyob ib ncig ntawm txhua qhov hauv cov tshuaj khib nyiab, tiv thaiv qhov sib xyaw ntawm huab cua, ua rau nws ruaj khov thiab ua haujlwm ntev.
nce durability
Kev hloov kho qhov nro tsim los ntawm HPMC hauv mortar qhuav ua rau nws ruaj khov dua thiab tiv thaiv cov mortar los ntawm kev tawg thiab tawg thaum lub sijhawm.Kev sib koom ua ke ntawm HPMC ntxiv dag zog rau cov khoom tiav, ua rau nws ruaj khov dua thiab tiv taus hnav thiab tsim kua muag hauv ntau qhov chaw ib puag ncig.Kev ruaj ntseg imparted los ntawm HPMC kuj txo cov dej nkag mus, yog li txo qhov kev loj hlob ntawm pwm thiab lwm yam khoom tsis zoo.
Txhim kho huab cua tsis kam
HPMC pab kom qhuav mortars kom ruaj khov nyob rau hauv huab cua huab cua, impressively withstanding hloov kub, los nag thiab av noo.Nws ua rau kom muaj zog ntawm cov tshuaj khib nyiab thiab ua kom cov dej nkag mus rau hauv cov khoom sib xyaw ua ke, uas tuaj yeem ua rau lub mortar puas yog tias nws raug dej rau lub sijhawm ntev.HPMC kuj tseem pab txo qis carbonation ntawm txheej txheej, tiv thaiv cov khoom kawg los ntawm cov pa roj carbon dioxide raug thiab ua rau degradation.
HPMC tau dhau los ua cov khoom muaj nyob rau hauv kev tsim cov mortars qhuav vim nws muaj peev xwm hloov kho qhov nro, txhim kho dej tuav thiab txhim kho kev ua haujlwm.Los ntawm kev txhim kho adhesion, cov neeg tsim khoom thiab cov neeg cog lus tuaj yeem tsim cov qauv muaj zog, txhim khu kev qha ntau dua uas yuav tsis tawg thiab hnav.Cov txiaj ntsig ntawm kev ntxiv HPMC rau cov khib nyiab qhuav tau raug pov thawj los ua kom cov kav ntev, ua haujlwm tau zoo, huab cua zoo thiab ruaj khov ntawm cov khoom sib xyaw qhuav, ua rau kev sib xyaw ntawm HPMC rau hauv mortars yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm zoo masonry.Los ntawm kev siv HPMC hloov cov tshuaj khib nyiab qhuav, cov neeg tsim khoom tuaj yeem tsim cov khoom zoo, dej-tiv taus thiab ziab sai uas txo cov sijhawm ua haujlwm thiab ua rau thaj chaw zoo nkauj thiab nyab xeeb.
