1. HydroxyPropyyl methylcellulose (HPMC)yog cov tsis muaj ionic cellulose ither ua los ntawm ntuj paj rwb fiber ntau lossis ntoo pulp los ntawm kev ua yeeb yam xws li alkhalization, etherization, thiab refining. Raws li nws viscosity, HPMC tuaj yeem faib ua cov khoom siv viscosity siab, nruab nrab ntawm cov khoom viscosity, thiab cov viscosity khoom lag luam tsawg. Ntawm lawv, qis viscosity HPMC tau siv dav hauv ntau daim teb vim nws cov khoom dej zoo heev, zaj duab xis-ua yeeb yaj kiab, thiab dispersion ruaj khov.
2. Cov yam ntxwv yooj yim ntawm cov viscosity qis HPMC
Dej solubility: qis vepcosity HPMC yog yooj yim solmle hauv dej txias thiab tuaj yeem tsim cov tshuaj txias lossis tsis muaj dej khov nyob hauv dej kub thiab feem ntau cov kuab tshuaj.
Tsis muaj viscosity: piv nrog nruab nrab thiab siab viscosity HPMC, nws cov kev daws teeb meem muaj qhov qis viscosity, feem ntau 5-100-are daws, 25 ° C).
STABILITY: Nws muaj cov tshuaj ruaj khov zoo, yog qhov tsis txaus siab rau cov kua qaub thiab alkalis, thiab tuaj yeem tswj tau ruaj khov nyob rau hauv ntau qhov dav.
Zaj duab xis-nws tuaj yeem tsim cov yeeb yaj kiab tsis zoo nyob rau saum npoo ntawm cov sib txawv, nrog kev thaiv zoo thiab cov khoom nplaum thiab cov nplaum nplaum.
Lubricity: Nws tuaj yeem siv ua cov roj nplua nyeem kom txo kev sib txhuam thiab txhim kho cov haujlwm ntawm cov khoom siv.
Cov haujlwm saum npoo: Nws muaj qee yam emulsification thiab dispersing muaj peev xwm thiab tuaj yeem siv rau hauv cov kaw lus ruaj khov.
3. Cov ntawv thov ntawm cov viscos tsawg-viscosity HPMC
Tsev cov ntaub ntawv
Tshuaj khib nyiab thiab cov tshuaj khib qhuav, thiab plastering cug, txhim kho cov dej huv, txhim kho cov dej tshuaj khib nyiab, thiab tiv thaiv kev tawg thiab kev sib tawg.
Cov nplaum nplaum: Nws yog siv los ua cov tuab thiab muaj zog txhim kho kev tsim kho kom yooj yim thiab kev sib haum xeeb.
Cov xim pleev xim rau cov xim tha xim: Raws li cov tuab thiab tshem tawm cov stabilizer, tiv thaiv cov xim xim sedimentation, thiab txhim kho kev txhuam hniav thiab kev txhuam hniav thiab theem.
Tshuaj thiab Khoom Noj
Kws Tsim Tshuaj Ntsuam Xyuas: Qis-Viscosity HPMC tuaj yeem siv rau hauv ntsiav tshuaj, kev raug tshem tawm, thiab tshuaj ntsiav, thiab tso tawm qeeb.
Cov khoom noj ntxiv rau zaub mov: siv raws li thickeners, emulsifiers, xws li kev txhim kho cov khoom noj thiab cov khoom noj thiab kua txiv.
Tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej
Hauv cov khoom lag luam tawv nqaij, cov tshuaj ntxuav lub ntsej muag, cov tshuaj ntxuav tes, tshuaj ntsuab thiab cov khoom siv Hrowbc tuaj yeem siv tau yooj yim rau kev thov thiab txhim kho daim tawv nqaij kom yooj yim.
Ceramics thiab papermaking
Hauv kev lag luam ceramic, HPMC tuaj yeem siv los ua cov roj nplua nyeem thiab moulding pab kom txhim kho cov av nkos thiab txhim kho lub zog ntawm lub cev.
Hauv kev lag luam papermaking, nws tuaj yeem siv rau cov ntawv txheej txhawm rau txhim kho lub ntsej muag du thiab luam ntawv yoog tau ntawm daim ntawv.
Kev Ua Liaj Ua Teb thiab Kev Tiv Thaiv Ib Cheeb Tsam
Tsis muaj viscosity HPMC tuaj yeem siv rau hauv kev noj tshuaj tua kab kom txhim kho kev ruaj ntseg siv sijhawm.
Hauv cov ntaub ntawv zoo ib puag ncig, xws li cov dej ntxiv, plua plav plua plav, thiab lwm yam, nws tuaj yeem txhim kho kev faib tawm ruaj khov thiab txhim kho cov nyhuv siv.
4. Siv thiab cia ntawm cov viscosity qis HPMC
Txoj kev siv
Tsis muaj viscosity HPMC feem ntau yog muab rau hauv cov hmoov lossis cov ntawv sib dhos thiab tuaj yeem ua tau ncaj qha rau hauv dej rau siv.
Txhawm rau tiv thaiv cov agglomeration, nws raug nquahu kom maj mam ntxiv HPMC rau dej txias, do tusyees thiab tom qab ntawd kub kom yaj kom tau txais cov nyhuv zoo.
Nyob rau hauv cov hmoov hmoov nplej qhuav, nws tuaj yeem sib xyaw uayees nrog lwm cov hmoov hmoov thiab ntxiv rau dej txhawm rau txhim kho kev ua haujlwm sib txawv.
Yuav tsum yuav tsum tau cia
HPMC yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, muaj cua kom zoo kom tsis txhob kub thiab av noo.
Tseg kom deb ntawm cov oxidants muaj zog los tiv thaiv cov kev coj noj coj ua los ntawm kev ua kom hloov kev ua tau zoo.
Qhov chaw cia kub tso kom pom zoo kom tswj tau ntawm 0-30 ℃ thiab zam kev ua tshav ntuj ncaj qha kom ntseeg tau tias qhov ruaj khov thiab kev pabcuam lub neej ntawm cov khoom.
Tsis muaj viscosity holroxypropyl methyluloseUa lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam xws li cov ntaub ntawv tsim kho tsev, tshuaj lom neeg, cov tshuaj pleev ib ce, dej tuav thiab ua yeeb yaj kiab ua yeeb yam. Nws cov yam ntxwv viscosity qis ua rau nws haum rau kev thov cov xwm txheej uas yuav tsum muaj fluarios uas xav tau fluidity, dispersibility thiab dispility. Nrog kev tsim kho cov thev naus laus zis ntawm kev lag luam muaj kev lag luam muaj txiaj ntsig qis dua, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav, thiab nws yuav qhia dav dav ntxiv rau kev txhim kho cov khoom lag luam thiab ua kom zoo dua qub txheej txheem.
