- Lub Sijhawm Qhib Ntau Ntxiv
- Vim Li Cas Nws Tseem Ceeb: Lub sijhawm qhib ntev dua tso cai rau cov neeg ua haujlwm kho thiab tso cov khoom siv xws li vuas lossis cib yam tsis tas maj.
- Lub luag haujlwm ntawm HPMC: Los ntawm kev ua kom cov dej noo qeeb zuj zus, HPMC muab sijhawm ntau dua los ua haujlwm nrog cov khoom ua ntej nws teeb tsa.
- Cov txiaj ntsig tseem ceeb:
- Txhim kho qhov tseeb ntawm kev tso pobzeb.
- Txo cov khib nyiab uas tshwm sim los ntawm kev teeb tsa ua ntej lub sijhawm.
- Txhim kho kev ywj pheej hauv cov haujlwm loj.
- Kev nplaum zoo dua
- Vim Li Cas Nws Tseem Ceeb: Kev nplaum ruaj khov yog qhov tseem ceeb rau lub neej ntev ntawm cov ntaub ntawv tsim kho, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej nyuaj.
- Lub luag haujlwm ntawm HPMC: HPMC tsim cov zaj duab xis nplaum zoo rau ntawm cov nplaim, txhim kho lub zog sib txuas ntawm cov khoom siv thiab cov khoom siv.
- Cov txiaj ntsig tseem ceeb:
- Tiv thaiv kom cov vuas, cov txheej txheej, lossis cov plasters tsis sib cais.
- Ua kom ruaj khov thiab ntseeg tau.
- Txo cov nqi kho txij nkawm dhau sijhawm.
- Kev Tiv Thaiv Kab Mob
- Vim Li Cas Nws Tseem Ceeb: Thaum siv cov ntaub ntawv xws li plaster lossis mortar rau ntawm cov chaw ntsug, qhov sagging tuaj yeem ua rau tsis sib npaug thiab tsis zoo nkauj.
- Lub luag haujlwm ntawm HPMC: HPMC txhim kho cov khoom thixotropic ntawm cov khoom sib xyaw, kom ntseeg tau tias lawv nyob hauv qhov chaw txawm tias thaum siv rau ntawm qhov chaw ntsug lossis saum toj.
- Cov txiaj ntsig tseem ceeb:
- Ua tiav cov txheej tuab sib xws.
- Txhim kho qhov zoo ntawm tag nrho cov xim tiav.
- Txo cov khoom pov tseg.
- Kub thiab pH Stability
- Vim Li Cas Nws Tseem Ceeb: Cov chaw tsim kho feem ntau ua rau cov ntaub ntawv raug rau ntau qhov kub thiab pH sib txawv.
- Lub luag haujlwm ntawm HPMC: HPMC tswj nws cov kev ua tau zoo thoob plaws ntau qhov kub thiab pH, ua kom muaj txiaj ntsig zoo sib xws.
- Cov txiaj ntsig tseem ceeb:
- Haum rau ntau yam huab cua sib txawv.
- Kev ua tau zoo hauv ob qho tib si acidic thiab alkaline ib puag ncig.
- Ua rau cov khoom siv ntau yam dua.
- Kev Phooj Ywg Zoo Rau Ib puag ncig
- Vim Li Cas Nws Tseem Ceeb: Kev ruaj khov yog qhov kev txhawj xeeb loj hlob hauv kev lag luam kev tsim kho.
- Lub luag haujlwm ntawm HPMC: Ua ib yam khoom uas tsis muaj tshuaj lom, biodegradable, HPMC pab txhawb rau kev tsim cov ntaub ntawv tsim kho uas zoo rau ib puag ncig.
- Cov txiaj ntsig tseem ceeb:
- Txo kev siv cov tshuaj lom neeg tsim.
- Ua kom lub neej ntawm cov ntaub ntawv zoo dua.
- Ua raws li cov qauv kev tsim vaj tsev ntsuab.
