Hydroxypropyl methylcellulose (HPMC) gypsum-raws li qhuav-mixed mortar additive

Gypsum-raws li qhuav-mixed mortar yog ib hom tshiab ntawm cov khoom siv phab ntsa dav siv hauv kev tsim kho. Nws lub ntsiab tivthaiv yog gypsum, ntxiv los ntawm lwm cov ntaub ntawv sau thiab tshuaj additives. Txhawm rau txhim kho kev ua haujlwm ntawm gypsum-raws li cov tshuaj khib nyiab qhuav, nws yog ib qho tsim nyog yuav tsum tau ntxiv ib qho tshwj xeeb additive-Hydroxypropyl methylcellulose (HPMC). HPMC muaj ntau yam haujlwm xws li thickening, dej tuav, thiab lubrication, thiab plays lub luag haujlwm tseem ceeb hauv gypsum-raws li cov tshuaj khib nyiab qhuav.

1. Lub luag hauj lwm ntawm HPMC nyob rau hauv gypsum-raws li qhuav mortar
Txhim khu kev tuav dej
Gypsum-raws li qhuav-sib tov mortar yuav tsum muaj ib tug tej yam degree ntawm noo noo nyob rau hauv lub sij hawm ntev thaum lub sij hawm tsim kho kom nws lub zog thiab adhesion tom qab hardening. HPMC muaj peev xwm tuav tau dej zoo, uas tuaj yeem txo qhov poob dej thaum lub sijhawm tsim kho thiab ua kom muaj kev ua haujlwm ntawm gypsum mortar ua ntej hardening. Tshwj xeeb tshaj yog nyob rau hauv qhuav thiab kub kev tsim kho ib puag ncig, dej tuav yog ib qho tseem ceeb tshwj xeeb, uas yuav pab kom ntev lub sij hawm tsim kho thiab txhim kho kev tsim kho kom zoo.

Thickening nyhuv
Raws li cov thickener, HPMC tuaj yeem txhim kho qhov sib xws ntawm gypsum-raws li cov khoom sib xyaw qhuav thiab ua kom yooj yim ntawm kev tsim kho. Cov nyhuv thickening tuaj yeem ua rau cov mortar smoother thaum lub sij hawm tsim kho, tsis tshua muaj sag, thiab txhim kho stability thiab efficiency ntawm kev tsim kho. Cov nyhuv thickening kuj tseem tuaj yeem pab txhim kho cov tshuaj khib nyiab los tiv thaiv sagging thiab tsis txhob cuam tshuam cov mortar txheej los ntawm sagging.

Txhim kho lubrication kev ua haujlwm
Thaum lub sij hawm tsim kho, cov nyhuv lubrication ntawm HPMC tuaj yeem txhim kho cov tshuaj khib nyiab kom sib kis tau zoo, ua rau cov gypsum mortar yooj yim dua rau ntawm phab ntsa, yog li txhim kho kev tsim kho thiab kev ua haujlwm. Lub lubrication zog ntawm HPMC kuj tseem tuaj yeem txo qhov kev sib txhuam ntawm cov cuab yeej siv thiab mortar, txhim kho qhov yooj yim ntawm kev tsim kho.

Txhim kho cov khoom sib txuas
Lub zog sib txuas ntawm gypsum-raws li qhuav-siv mortar ncaj qha cuam tshuam rau kev tsim kho zoo. HPMC tuaj yeem txhim kho qhov adhesion ntawm mortar rau lub substrate, txhim kho kev sib raug zoo ntawm mortar, ua kom nws muaj zog tom qab ziab, thiab txo qhov muaj peev xwm ntawm kev tawg. Qhov no feature yog ib qho tseem ceeb los xyuas kom meej qhov zoo thiab durability ntawm kev tsim kho.

2. Qhov zoo ntawm HPMC
Kev tiv thaiv ib puag ncig
HPMC yog cov khoom tsis muaj tshuaj lom thiab tsis muaj mob uas ua tau raws li cov qauv kev tiv thaiv ib puag ncig. Raws li cov khoom lag luam cellulose ether, kev siv HPMC yuav tsis tsim cov pa phem lossis pov tseg, thiab yuav tsis ua rau lub nra hnyav rau ib puag ncig. Nws yog ib tug ntsuab thiab ib puag ncig tus phooj ywg lub tsev additive.

Tshuaj stability
HPMC qhia tau hais tias muaj kev ruaj ntseg zoo heev hauv gypsum-raws li cov tshuaj khib nyiab qhuav, yuav tsis hnov ​​​​mob rau lwm yam tshuaj lom neeg, thiab nws qhov kev ua tau zoo nyob ruaj khov nyob rau hauv ib puag ncig sib txawv. Txawm hais tias nyob rau hauv qhov kub thiab txias, qhov kub thiab txias, qhov chaw ntub lossis qhuav, kev ua haujlwm ntawm HPMC tuaj yeem lav tau thiab yuav tsis poob vim kev hloov ib puag ncig.

Durability
HPMC tuaj yeem txhim kho qhov ua tau zoo ntawm cov gypsum-raws li cov tshuaj khib nyiab qhuav thiab txo qhov tawg thiab tev ntawm cov tshuaj khib nyiab. Nws cov kav ntev ua rau tag nrho cov qauv ntawm gypsum mortar ruaj khov, txo tus nqi ntawm kev saib xyuas tom qab, thiab muab kev lees paub rau kev siv lub tsev mus ntev.

Muaj zog adaptability
HPMC tuaj yeem hloov mus rau ntau hom substrates, suav nrog pob zeb, masonry, aerated qhob, thiab lwm yam, thiab qhia tau tias muaj kev sib raug zoo. Qhov no tso cai rau gypsum-raws li qhuav-siv mortar tau dav siv nyob rau hauv ntau yam khoom siv hauv tsev, muab cov kev daws teeb meem yooj yim rau kev tsim kho sib txawv.

3. Yuav tsum tau siv HPMC nyob rau hauv gypsum-raws li qhuav-siv mortar
Txhim kho kev tsim kho kom zoo
Kev tsim kho niaj hnub no muaj kev xav tau ntau dua thiab siab dua rau kev ua tau zoo, thiab kev siv HPMC tuaj yeem txhim kho kev ua haujlwm ntawm gypsum-raws li cov khoom sib xyaw qhuav, ua kom nws txoj kev tsim kho, thiab ua tau raws li cov kev xav tau ntawm kev tsim kho sai. Qhov no yog qhov tshwj xeeb tshaj yog rau cov kev tsim kho loj, uas tuaj yeem ua rau lub sijhawm tsim kho thiab txuag nqi zog.

Txhim kho kev tsim kho kom zoo
Kev tsim kho zoo ncaj qha cuam tshuam rau kev nyab xeeb thiab kav ntev ntawm lub tsev. Qhov ntxiv ntawmHPMCtuaj yeem txhim kho cov dej tuav, adhesion thiab tawg tsis kam ntawm mortar, ua rau cov mortar txheej tom qab kev tsim kho smoother thiab firmer, txo qhov kev xav tau ntawm rework thiab tu, thiab xyuas kom meej tag nrho cov stability ntawm lub tsev.
