1. Kev txhais ntawm HPMC
HPMC (Hydroxypropyl Methyl Cellulose)yog ib qho cellulose ether uas tsis yog ionic siv dav hauv cov ntaub ntawv siv hauv kev tsim kho, tshuaj, khoom noj, tshuaj lom neeg txhua hnub thiab lwm yam lag luam. Hauv cov mortar qhuav, AnxinCel®HPMC feem ntau yog siv los ua cov khoom ua kom tuab, cov neeg sawv cev khaws dej thiab cov khoom hloov kho, uas tuaj yeem txhim kho kev ua tau zoo ntawm mortar.
2. Lub luag haujlwm ntawm HPMC hauv cov tshuaj khib qhuav sib xyaw
Cov haujlwm tseem ceeb ntawm HPMC hauv cov tshuaj mortar qhuav yog raws li nram no:
Kev khaws dej: HPMC tuaj yeem nqus dej thiab o, tsim cov zaj duab xis hydration hauv cov mortar, txo qhov evaporation ntawm dej sai, txhim kho qhov ua tau zoo ntawm cov cement lossis gypsum, thiab tiv thaiv kev tawg lossis lub zog poob los ntawm kev poob dej ntau dhau.
Ua kom tuab: HPMC muab cov mortar zoo thixotropy, ua rau cov mortar muaj cov kua dej thiab cov khoom siv tsim kho kom zoo, thiab zam kev nqus dej thiab cov av los ntawm kev sib cais dej.
Txhim kho kev ua tau zoo ntawm kev tsim kho: HPMC txhim kho qhov lubricity ntawm mortar, ua rau nws yooj yim dua rau kev thov thiab theem, thaum txhim kho kev nplaum rau lub substrate thiab txo cov hmoov thiab hollowing.
Ntev lub sijhawm qhib: AnxinCel®HPMC tuaj yeem ua rau qeeb qeeb ntawm cov dej evaporation, ntev lub sijhawm ua haujlwm ntawm cov mortar, ua rau kev tsim kho yooj ywm dua, thiab tshwj xeeb tshaj yog tsim rau kev siv thaj chaw loj thiab qhov chaw tsim kho kub siab.
Tiv thaiv kev sagging: Hauv cov ntaub ntawv tsim kho ntsug xws li cov nplaum pobzeb thiab cov putties, HPMC tuaj yeem tiv thaiv cov khoom kom tsis txhob swb vim nws qhov hnyav thiab txhim kho kev ruaj khov ntawm kev tsim kho.
3. Daim ntawv thov ntawm HPMC hauv cov mortars sib xyaw sib txawv
HPMC yog siv dav hauv ntau hom mortars qhuav, suav nrog tab sis tsis txwv rau:
Cov tshuaj khib masonry thiab cov tshuaj khib plastering: txhim kho kev khaws dej, tiv thaiv cov tshuaj khib tawg, thiab txhim kho kev nplaum.
Cov nplaum rau pobzeb: txhim kho kev nplaum, txhim kho kev yooj yim ntawm kev tsim kho, thiab tiv thaiv cov pobzeb kom tsis txhob plam.
Cov tshuaj nplaum uas nws tus kheej leveling: txhim kho kev fluidity, tiv thaiv stratification, thiab txhim kho lub zog.
Cov tshuaj khib tsis pub dej nkag: txhim kho kev ua haujlwm tsis pub dej nkag thiab ua kom cov tshuaj khib ceev dua.
Hmoov putty: txhim kho kev ua haujlwm ntawm kev tsim kho, txhim kho kev tiv thaiv txhuam, thiab tiv thaiv hmoov.
4. Kev xaiv thiab siv HPMC kev ceev faj
Cov khoom siv mortar sib txawv muaj cov kev cai sib txawv rau HPMC, yog li cov hauv qab no yuav tsum tau xav txog thaum xaiv:
Viscosity: AnxinCel®HPMC uas muaj viscosity tsawg yog qhov tsim nyog rau cov mortar uas nws tus kheej leveling nrog cov kua dej zoo, thaum HPMC uas muaj viscosity siab yog qhov tsim nyog rau cov putty lossis cov nplaum pobzeb uas muaj dej ntau.cov kev cai khaws cia.
Kev yaj: HPMC zoo yuav tsum muaj kev yaj zoo, tuaj yeem tawg sai thiab tsim cov tshuaj sib xws yam tsis muaj kev sib sau ua ke lossis kev sib sau ua ke.
Tus nqi ntxiv: Feem ntau, tus nqi ntxiv ntawm HPMC hauv cov tshuaj khib qhuav yog 0.1% ~ 0.5%, thiab qhov sib piv tshwj xeeb yuav tsum tau hloov kho raws li qhov yuav tsum tau ua ntawm cov tshuaj khib.
HPMCyog ib qho khoom siv tseem ceeb hauv cov tshuaj mortar qhuav, uas tuaj yeem txhim kho kev ua haujlwm ntawm kev tsim kho, kev khaws dej thiab kev nplaum ntawm cov tshuaj mortar. Nws yog siv dav hauv cov tshuaj mortar masonry, plastering mortar, vuas nplaum, putty thiab lwm yam khoom. Thaum xaiv HPMC, nws yog qhov tsim nyog los phim cov viscosity thiab mis raws li qhov xwm txheej thov tshwj xeeb kom ntseeg tau tias qhov zoo tshaj plaws ntawm kev tsim kho.
