HydroxyPropyyl Methylcellulose (HPMC), raws li lub tsev tseem ceeb tsim cov khoom siv ntxiv, yog siv dav hauv cov txheej txheej porcelain, tshwj xeeb tshaj yog nyob rau hauv cov mis ntawm cov hmoov yas cov hmoov av. Nws tsis tuaj yeem txhim kho kev tsim kho cov kev tsim kho ntawm cov txheej, tab sis kuj tseem txhim kho cov dej tsis kam, cov qauv nplaum thiab kev ua haujlwm ntawm cov txheej.
1. Cov khoom ntawm hydroxypropyl methylcellose
HydroxyPropylenCellulose yog dej-soluble polymer compound los ntawm ntuj cog cellulose. Nws cov yam ntxwv tseem ceeb muaj xws li:
Thickening:Kimacell® Tus neeg tuaj yeem nce cov viscosity ntawm txheej, ua cov txheej xim ruaj khov thaum kev tsim kho.
Dej Solubility:Nws muaj cov dej ua kom zoo thiab tuaj yeem ua cov tshuaj ruaj khov hauv dej.
Zaj duab xis-ua cov cuab yeej:Nws tuaj yeem tsim cov yeeb yaj kiab niaj hnub thiab txhim kho lub ntsej muag du thiab sib txig sib luag ntawm cov txheej.
Adhesion:Txhim kho cov nplaum ntawm cov txheej txheem rau lub hauv paus nto (xws li MAAs, Masonry, Ntoo, thiab lwm yam).
Txhim kho cov haujlwm ntawm cov txheej:Nws tuaj yeem hloov cov kua dej thiab dej ua kom muaj zog ntawm cov hmoov hmoov qhuav, txuas ntxiv lub sijhawm ua haujlwm, thiab zam kom qhuav ziab.
2. Lub luag haujlwm ntawm hydroxypropyl methylcellose hauv cov hmoov qhuav phaj (zoo li xim
Nyob rau hauv cov hmoov qhuav phaj (porcelain) zoo li xim, hpmc feem ntau ua tau txoj haujlwm hauv qab no:
Thickening thiab kho viscosity:Cov nyhuv tuab ntawm HPMC ua kom cov xim muaj cov xim zoo nkauj thaum siv thiab siv, thiab nws tsis yooj yim los tsim cov sagging.
Txhim kho kev tsim kho:Los ntawm kev kho cov dej khov thiab dej muaj peev xwm txhim kho lub sijhawm qhib, nws tuaj yeem txuas lub xim qhib, ua rau cov xim kom yooj yim rau kev thov thiab txiav.
Txhim kho Adhesion:HPMC tuaj yeem txhim kho cov nplaum ntawm cov xim pleev xim rau ntawm cov xim pleev xim, tshwj xeeb yog Masonry substrates lossis Masonry substrates lossis Masonry cov nplaum thiab ua kom muaj zog tshaj ntawm cov xim pleev xim.
Tiv thaiv kom tiv thaiv sedimentation thiab stratification:HPMC muaj cov khoom zoo tshem tawm, uas tuaj yeem zam kom zoo zam cov kev ua kom qhuav ntawm cov xim qhuav kom qhuav thaum lub sijhawm nres.
Kev txhim kho cov dej tsis kam thiab tawg tawm tsam:HPMC tuaj yeem txhim kho cov dej tsis kam ntawm cov txheej, nce cov xim tsis zoo ntawm cov txheej, thiab ua kom cov txheej ntub dej khov kho thaum nws ntub lossis sab nraud ib puag ncig hloov zoo.
3. Cov tshuaj ib txwm ntawm cov hmoov av uas muaj cov hmoov av
Hmoov hmoov imitation porcelain xim feem ntau muaj cov khoom sib xyaw tseem ceeb hauv qab no:
Inorganic fillers:Xws li Talcum hmoov, hmoov ntau calcium yog siv los kho cov qauv thiab tawv tawv ntawm cov xim thiab pab kom cov nyhuv zoo.
Resin lossis Emulsion:Feem ntau siv resins suav nrog acrylic resin, polyurethane cob, thiab lwm yam tuaj yeem txhim kho cov nplaum, hardness thiab huab cua tsis kam ntawm cov xim.
Hloov cellulose:xws li HPMC, lub ntsiab muaj nuj nqi ntawm hom tshuaj no yog los kho lub viscosity, fundity, worsility, kev ruaj khov ntawm cov xim.
Colorant:xws li cov xim pig thov, siv los kho cov xim ntawm cov xim pleev xim, cov uas yog cov xim titiocium, carbon dub, thiab lwm yam.
Tshuaj Tiv Thaiv:Siv los tiv thaiv kev loj hlob ntawm cov kab mob me me hauv cov xim thiab xyuas kom cov kev pabcuam lub neej ntawm cov xim.
Planizer thiab tus neeg sawv cev saib xyuas:Siv los txhim kho lub ntsej muag du ntawm txheej thiab zam kev ntxhib los mos ntawm cov txheej txheej.
4. Qhov nyiaj thiab piv ntawm HPMC hauv cov hmoov qhuav moritation phaj
Nyob rau hauv cov hmoov cov hmoov imitation porcelain xim, tus nqi HPMC ntxiv rau cov nyiaj tau los txog 0.5% -2% ntawm tag nrho cov xim xim. Qhov sib piv tshwj xeeb yog nyob ntawm qhov uas yuav tsum tau ua. Cov hauv qab no yog cov qauv sib piv (noj 10 kg qhuav txheej ua piv txwv):
Inorganic muab tub lim (Talcum hmoov, hmoov av muaj hmoov av, thiab lwm yam):Txog 6-7 kg
Resin:Txog 1.5-2 kg
HydroxyPropyyl methylcellulose (HPMC):txog 0.05-0.2 kg
Xim (xws li titanium dioxide):txog 0.5-1 kg
Tshuaj Tiv Thaiv:txog 0.05 kg
Planizer thiab tus neeg sawv cev saib xyuas:txog 0.1 kg
Cov kev hloov kho ntawm lub cev yuav tsum tau txiav txim siab raws li kev tsim kho cov chaw tsim qauv thiab cov kev ua tau zoo ntawm HPMC siv yuav tsum tau ua kom zoo rau.
5. Kev siv thiab ceev faj
Thaum siv HPMC, nws raug nquahu kom ua raws cov theem hauv qab no:
Ua ntej ntub ua ntej sib xyaw: Kimacell® yuav tsum sib xyaw nrog lwm cov khoom siv roj raw, kom nws tuaj yeem ua ntej ntxiv lwm cov khoom xyaw, yog li kom tsis txhob hpmc agglomeration.
Qeeb qeeb:Thaum sib xyaw lwm cov hmoov qhuav dej,HPMCyuav tsum tau ntxiv maj mam kom tsis txhob ua tiav kev ua tiav vim yog kev sib ntxiv sai ntxiv.
Tusyees xyaw dawb:Hauv cov qauv, tag nrho cov khoom xyaw yuav tsum tau sib xyaw uayees kom ntseeg tau tias HPMC tuaj yeem ua tiav nws lub luag haujlwm hauv txheej.
Kev Cia Cai Cia:Hmoov hmoov imitting porcelain txheej yuav tsum muab cia rau hauv qhov chaw qhuav thiab txias kom tsis txhob kub thiab cov av noo cuam tshuam rau qhov zoo ntawm txheej.
Daim ntawv thov ntawm hydroxypropyl methylcellose nyob rau hauv cov hmoov f hmoov iMitects tuaj yeem txhim kho cov txheej txheem kev tsim kho porcelain tuaj yeem txhim kho cov txheej, ua cov txheej ruaj khov thiab ruaj khov. Los ntawm cov qauv tsim tsim nyog no thiab kev siv cov hau kev, qhov zoo ntawm HPMC tuaj yeem hloov kho, thiab cov kev tsim kho yuav tuaj yeem ua tau. Hauv cov ntawv thov tiag tiag, tus nqi HPMC ntxiv yuav raug muab kho raws li cov xwm txheej tshwj xeeb kom ntseeg tau tias cov txheej txheem xav tau.
