1. Cov ntsiab lus ntawm HPMC
HPMC (HydroxyPropYth Cellulose)Yog cov tsis-ionic cellulose ionet dav siv nyob rau hauv cov ntaub ntawv hauv tsev, tshuaj, khoom noj khoom haus, txhua hnub tshuaj thiab lwm yam khoom siv. Nyob rau hauv qhuav-mixed-mixincel ®hpmc feem ntau yog siv los ua cov tuab yaj ntoo, dej-tswj hwm, uas tuaj yeem txhim kho kev tsim kho kev ua haujlwm ntawm cug.
2. Lub luag haujlwm ntawm HPMC hauv cov kab cug qhuav qhuav
Lub luag haujlwm tseem ceeb ntawm HPMC hauv qhuav-sib nphua tshuaj khib yog raws li hauv qab no:
Dej khaws cia: HPMC tuaj yeem nqus dej thiab o, ua kom muaj kev sib tsoo ntawm cov dej khov kho, thiab tiv thaiv kev tawg lossis lub zog poob los ntawm cov dej ntws ntau dhau.
Thickening: HPMC muab lub tshuaj khib zoo thixotropy, ua lub tshuaj khib nyiab muaj cov khoom haum kom tsim nyog thiab tsim kom muaj dej txaus thiab kev ua kom dej sib cais los ntawm dej sib cais.
Txhim kho kev tsim kho kev tsim kho: HPMC txhim kho kev tsim kho ntawm tshuaj khib, ua kom nws yooj yim dua rau kev thov thiab qib, thaum txhim kho cov hmoov av thiab txo cov hmoov thiab txo.
Ncua Sijhawm Pib: Kev ntxhov siab ®
Los tiv thaiv cov khoom siv ntsug xws li cov khoom siv sib txawv thiab cov khoom siv HPMC tuaj yeem tiv thaiv cov khoom ntawm vim nws tus kheej hnyav thiab txhim kho kev ruaj khov.
3. Daim ntawv thov ntawm HPMC nyob rau hauv txawv qhuav-morted mortars
HPMC tau dav hauv ntau hom kev sib xyaw ua ke, suav nrog tab sis tsis txwv rau:
Masonry cug thiab plastering cug: txhim kho cov dej ua ke, tiv thaiv txoj siav coll tawg, thiab txhim kho adchesion.
Pobzeb nplaum: Txhim Kho cov nplaum, txhim kho kev tsim kho kev tsim kho, thiab tiv thaiv cov vuas los ntawm kev swb.
Tus kheej-leveling cug: kev txhim kho kev ua kom muaj zog, tiv thaiv kev sib txawv, thiab txhim kho lub zog.
Waterproof Cug: txhim kho kev ua haujlwm tsis muaj dej thiab nce lub ntom ntom ntawm cug.
Putty hmoov: txhim kho kev tsim kho kev ua haujlwm, txhim kho cov txhuam kom tiv thaiv, thiab tiv thaiv hmoov.
4. HPMC xaiv thiab siv kev ceev faj
Cov khoom sib txawv ntawm cov khoom siv txawv muaj cov sib txawv rau HPMC, yog li cov hauv qab no yuav tsum tau txiav txim siab thaum xaiv:
Viscosity: Tsawg-viscosity txhawj xeeb txog tus kheej cug nrog cov tshuaj khib nyiab zoo, thaum lub siab viscos yog tsim nyog rau putty lossis vuas nplaum nrog dej siabKhaws cia.
Solubility: Zoo-zoo HPMC yuav tsum muaj solubility zoo, tuaj yeem ua kom tawg sai thiab tsim cov kev daws teeb meem tsis muaj agglomeration lossis agglomeration.
Ib qho ntxiv ntawm: Feem ntau, tus nqi ntawm HPMC hauv qhuav-sib xyaw ua ke yuav tsum tau hloov kho raws li cov kev xav tau ntawm cov tshuaj cug.
HPMCyog ib qho tseem ceeb ntxiv hauv cov tshuaj cug qhuav, uas tuaj yeem txhim kho kev ua haujlwm, dej khaws cia thiab nplaum ntawm cug. Nws yog dav siv hauv Masonry Collhu Chocolate, pobzeb nplaum, putty thiab lwm yam khoom. Thaum xaiv HPMC, nws yog ib qho tsim nyog kom phim cov viscosity uas tsim nyog thiab cov qauv raws li daim ntawv thov kev pabcuam tshwj xeeb kom ntseeg tau cov nyhuv zoo tshaj plaws.
