1. Kev txhais ntawm HPMC
HPMC (Hydroxypropyl Methyl Cellulose)yog ib qho uas tsis yog-ionic cellulose ether dav siv hauv cov khoom siv hauv tsev, tshuaj, khoom noj, tshuaj niaj hnub thiab lwm yam lag luam. Hauv cov tshuaj khib nyiab qhuav, AnxinCel®HPMC feem ntau yog siv los ua cov kua nplaum, cov dej tuav cov neeg ua haujlwm thiab hloov kho, uas tuaj yeem txhim kho kev tsim kho ntawm mortar.
2. Lub luag hauj lwm ntawm HPMC nyob rau hauv qhuav-mixed mortar
Lub luag haujlwm tseem ceeb ntawm HPMC hauv cov tshuaj khib nyiab qhuav yog raws li hauv qab no:
Kev tuav dej: HPMC tuaj yeem nqus dej thiab o, tsim cov hydration zaj duab xis hauv cov mortar, txo cov evaporation sai ntawm cov dej, txhim kho cov dej ua haujlwm ntawm cov cement lossis gypsum, thiab tiv thaiv kev tawg lossis lub zog poob los ntawm dej ntau dhau.
Thickening: HPMC muab cov mortar zoo thixotropy, ua rau cov mortar muaj qhov tsim nyog fluidity thiab kev tsim vaj tse, thiab zam dej seepage thiab sedimentation los ntawm dej sib cais.
Txhim kho kev tsim kho: HPMC txhim kho lubricity ntawm mortar, ua kom yooj yim rau kev thov thiab qib, thaum txhim kho adhesion rau substrate thiab txo cov hmoov thiab hollowing.
Nthuav lub sijhawm qhib: AnxinCel®HPMC tuaj yeem ua kom cov dej ntws qeeb qeeb, txuas ntxiv lub sijhawm ua haujlwm ntawm mortar, ua kom kev tsim kho tau yooj yim dua, thiab tshwj xeeb tshaj yog tsim rau thaj chaw loj thiab cov chaw tsim kho kub.
Los tiv thaiv sagging: Hauv cov khoom siv ntsug xws li cov nplais nplaum thiab cov pob zeb, HPMC tuaj yeem tiv thaiv cov khoom los ntawm kev zawv zawg vim nws qhov hnyav thiab txhim kho kev tsim kho.
3. Daim ntawv thov ntawm HPMC nyob rau hauv sib txawv qhuav sib tov mortars
HPMC yog dav siv nyob rau hauv ntau hom qhuav-siv mortars, suav nrog tab sis tsis txwv rau:
Masonry mortar thiab plastering mortar: txhim kho dej tuav, tiv thaiv mortar cracking, thiab txhim kho adhesion.
Pobzeb nplaum: txhim khu adhesion, txhim kho kev tsim kho yooj yim, thiab tiv thaiv cov vuas los ntawm kev swb.
Self-leveling mortar: txhim kho fluidity, tiv thaiv stratification, thiab txhim khu lub zog.
Waterproof mortar: txhim kho kev ua haujlwm tsis muaj dej thiab ua kom qhov ntom ntom ntawm mortar.
Putty hmoov: txhim kho kev tsim kho kev ua haujlwm, txhim khu kev txhuam, thiab tiv thaiv hmoov.
4. HPMC xaiv thiab siv ceev faj
Cov khoom sib txawv ntawm cov khoom sib txawv muaj qhov sib txawv rau HPMC, yog li cov hauv qab no yuav tsum tau txiav txim siab thaum xaiv:
Viscosity: Tsawg-viscosity AnxinCel®HPMC yog tsim rau tus kheej-leveling mortar nrog zoo fluidity, thaum high-viscosity HPMC yog haum rau putty los yog pobzeb nplaum nrog dej siab.cov cai khaws cia.
Solubility: High-quality HPMC yuav tsum muaj cov solubility zoo, muaj peev xwm disperse sai thiab tsim ib qho kev daws teeb meem tsis muaj agglomeration los yog agglomeration.
Ntxiv tus nqi: Feem ntau, qhov sib ntxiv ntawm HPMC hauv cov tshuaj khib nyiab qhuav yog 0.1% ~ 0.5%, thiab qhov kev faib ua feem yuav tsum tau hloov kho raws li qhov yuav tsum tau ua ntawm mortar.
HPMCyog ib qho tseem ceeb additive nyob rau hauv qhuav-mixed mortar, uas yuav txhim khu kev tsim kho kev ua tau zoo, dej tuav thiab adhesion ntawm mortar. Nws yog dav siv nyob rau hauv masonry mortar, plastering mortar, pobzeb nplaum, putty thiab lwm yam khoom. Thaum xaiv HPMC, nws yog ib qho tsim nyog yuav tsum ua kom haum rau qhov tsim nyog viscosity thiab cov qauv raws li qhov tshwj xeeb daim ntawv thov scenario kom ntseeg tau tias qhov kev tsim kho zoo tshaj plaws.
