HPMC (HydroxyPropyyl methylcellulose), ua ib qho tseem ceeb uas dej-soluble polymer tshuaj, yog siv dav hauv cov ntaub ntawv hauv tsev, tshwj xeeb tshaj yog nyob rau hauv phab ntsa putty thiab pobzeb cement. Nws tsis tuaj yeem txhim kho kev tsim kho kev tsim kho, tab sis kuj txhim kho kev siv cov txiaj ntsig ntawm cov khoom lag luam thiab nce lub durability ntawm txoj haujlwm.
1. Cov yam ntxwv ntawm HPMC
HPMC yog ib qho xim dawb tsis muaj xim thiab tsw ntxhiab dawb ua los ntawm cov tshuaj hloov kho lub cev hloov kho. Nws muaj cov dej zoo heev solubility thiab cov nplaum. Nws cov qauv tshuaj muaj ob pawg neeg tshuaj, hydroxypropyl thiab methyl, muab nws tej yam khoom tshwj xeeb:
Thickening: Thaum HPMC yog yaj hauv dej, nws tuaj yeem tsim cov tshuaj tua tau thiab nce viscosity ntawm cov cuab yeej ua yeeb yam thiab cov nplaum.
Dej khaws cia: Nws tuaj yeem tuav dej thiab tiv thaiv dej los ntawm kev nqus dej dhau sai sai, uas pab txhawb nqa thiab tsim kho ntawm cov xim.
Txhim kho kev tsim kho: Ua cov txheej txheem kev tsim kho thiab cov nplaum ntxiv, txo kev sib txhuam thaum lub sij hawm tsim kho, thiab txhim kho cov neeg ua haujlwm 'kev tsim kho.
Zaj duab xis-tsim cov khoom: muaj peev xwm ua ib zaj yeeb yaj kiab tsis zoo rau kev txhim kho cov xim nplaum.
2. Daim Ntawv Thov HPMC hauv Phab Ntsa Putty
Phab ntsa Putty yog ib qho khoom tseem ceeb hauv pleev xim kev tsim kho. Nws yog siv kom du cov phab ntsa thiab kho phab ntsa yam tsis xws luag. HPMC ua si lub luag haujlwm tseem ceeb ua ib qho kev ntxiv rau phab ntsa putty.
Txhim kho kev ua haujlwm ntawm Putty: Ntxiv tus nqi uas tsim nyog ntawm HPMC mus rau lub putty tuaj yeem txhim kho kev ua haujlwm ntawm lub putty. Vim tias cov nyhuv tuab ntawm HPMC, lub putty yog smoother thaum thov, txo kev tawm tsam thaum kev tsim kho thiab txhim kho kev tsim kho.
Txhim kho adchesion: kev sib sau ua yeeb yaj kiab ntawm HPMC ua rau lub putty kom zoo dua rau ntawm phab ntsa, txhim kho cov nplaum ntawm lub putty, thiab txwv tsis pub poob tawm lossis tawg.
Kev Txhim Kho Cov Dej Ua Haujlwm: Cov dej khaws cia ntawm HPMC tuaj yeem ncua kev ziab kom qhuav ntawm putty thiab txo qhov tshwm sim ntawm cov tawg kom qhuav. Tshwj xeeb tshaj yog thaum tsim ntawm thaj chaw loj, nws tuaj yeem ua kom ntseeg tau tias lub putty saum npoo av thiab sab hauv qhuav ib txhij kom zam dhau cov kab tawg kom qhuav ntawm ziab txheej txheej.
Tiv thaiv kev sib hais haum thiab stratification: cov khoom tuab tuab
3. Daim ntawv thov ntawm HPMC hauv Ceramic Pob zeb Maas Adhesive
Pobzeb Maas kua nplaum yog ib qho tseem ceeb siv rau kev khi cov vuas rau lub hauv paus nto thaum lub sij hawm cov nplais txheej txheej. Daim ntawv thov ntawm HPMC hauv Ceramic Pobzeb Maas Adhesive tau txhim kho cov kev ua tau zoo thiab kev tsim kho ntawm cov nplaum nplaum.
Txhim kho adchesion: kev sib ntxiv ntawm HPMC tuaj yeem txhim kho lub zog ntawm lub zog ntawm cov vuas khov kho, kom muaj cov vuas luaj li ua rau lub hauv paus thiab kev tiv thaiv cov vuas los ntawm kev poob. Tshwj xeeb tshaj yog qee qhov chaw du lossis tsis xwm yeem, HPMC tuaj yeem txhim kho cov nplaum ntawm cov nplaum ntawm cov kua nplaum thiab cov hauv paus.
Txhim kho kev ua haujlwm: ntxivHPMCYuav kom pob zeb xis mas kua nplaum muaj peev xwm txhim kho lub zog ua haujlwm ntawm cov kua nplaum. Thaum kev tsim kho, cov kua nplaum ua kom zoo dua thiab yooj yim ntawm cov haujlwm tsim kho, tso cai rau cov neeg ua haujlwm tsim kho los thov thiab kho qhov chaw ntawm cov vuas yooj yim dua.
Kev ua kom cov dej sib npaug: cov dej khaws cov nyhuv khaws cia ntawm HPMC yog qhov tshwj xeeb yog qhov tseem ceeb hauv pawg nplaum nplaum. Nws tuaj yeem qeeb qhov ziab nrawm ntawm Maas slurry, cia cov kua nplaum kom tswj kom raug viscosity kom zoo, zam kev tsim kho kom zoo lossis txo qis ntawm cov nroj tsuag ceramic tshwm sim los ntawm kev ziab khaub ncaws heev.
Txhim kho cov kab ke tiv thaiv: Thaum lub sijhawm ua kom qhuav ntawm cov xis mas lo kua nplaum, shrinkage lossis cov kab nrib pleb muaj tshwm sim. Los ntawm kev txhim kho lub viscosity thiab zaj duab xis-ua cov khoom ntawm cov teeb meem Maas, yog li txhim kho cov kev tsim kho tag nrho.
4. Lwm qhov zoo ntawm HPMC hauv cov ntaub ntawv tsim tsev
Kev tiv thaiv ib puag ncig: HPMC yog cov khoom ntsuab thiab ib puag ncig uas tsis yog-lom thiab tsis muaj mob, thiab yuav tsis ua rau muaj kev phom sij rau tib neeg lub cev thiab ib puag ncig. Yog li ntawd, nws daim ntawv thov hauv kev tsim kho kev tsim kho cov cai niaj zaus.
Kev lag luam: HPMC tuaj yeem ua tiav cov txiaj ntsig tseem ceeb nrog kev siv nyiaj tsawg thiab muaj kev ua tau zoo siab. Nws ntxiv tuaj yeem txhim kho qhov zoo ntawm phab ntsa putty thiab pobzeb cement, thaum txo cov nqi tsim khoom.
Muaj zog hloov tau: HPMC muaj kev sib raug zoo nrog lwm cov khoom siv hauv tsev xws li Cementum, LineX, thiab lwm yam tuaj yeem hloov kho tau raws li qhov xav tau kev tsim kho.
Daim ntawv thov ntawmHPMCHauv phab ntsa putty thiab pobzeb cemention, kev tsim kho thiab durability ntawm cov khoom, tab sis kuj zoo tiv thaiv cov kab nrib pleb, kev sib hais haum thiab lwm yam teeb meem. Raws li ib puag ncig tus phooj ywg, yig thiab txuag kev ntxiv, hpmc muab cov khoom siv zoo rau kev tsim kho niaj hnub no. Raws li kev tsim txom kev tsim kho txuas ntxiv mus nrhiav kev tiv thaiv ib puag ncig thiab kev siv HPMC yuav dhau los ua kev txhim kho ntau dua ntawm cov ntaub ntawv hauv tsev.
