Muaj Cov Qeb Hydraulic Hydropropy (HPMC) yog cov khoom tsis-ionic ntawm lub ntsej muag ua los ntawm cov xov tooj ntawm lub ntsej muag. Nws lub ntsiab raw khoom yog paj rwb lossis ntoo pulp, thiab nws tau npaj los ntawm ntau cov txheej txheem xws li kev ua alchalization, etheremation, ntxuav, thiab kom qhuav. Vim tias HPMC muaj qhov ua tau zoo heev, raug tshem tawm, kev sib koom ua ke, kev tiv thaiv kev ua yeeb yam, kev tiv thaiv kev ua haujlwm, tshuaj pleev ib ce, tshuaj thiab lwm thaj chaw.
1. Cov yam ntxwv ntawm HPMC
Solubility thiab ruaj khov
HPMC yog soluble hauv dej txias thiab qee cov kuab tshuaj organic thiab muaj cov dej solubility zoo. Nws yog insoluble hauv dej kub, tab sis tuaj yeem tsim cov gel hauv dej, thiab cov tshuaj daws tau muaj muaj siab transparency thiab ruaj khov. Tsis tas li ntawd, HPMC muaj kev ruaj khov zoo heev, thiab feem ntau tswj hwm kev ua tau ruaj khov nyob rau hauv thaj tsam ntawm 3 ~ 11.
Dej khaws cia thiab thickening
HPMC muaj lub peev xwm ua kom muaj zog heev thiab tuaj yeem tiv thaiv dej poob. Cov cuab yeej no ua rau nws ua lub luag haujlwm tseem ceeb hauv cov xis nyob hauv cov kev tsim kho, txhim kho kev tsim kho thiab zam kev tawg. Tsis tas li ntawd, HPMC yog qhov kev siv tshuab ua kom zoo dua qub, thiab nws cov kua aqueous tuaj yeem muab viscosity nyob ntawm cov kev ua kom muaj ntau.
Zaj duab xis-ua cov cuab yeej
HPMC tuaj yeem tsim cov yeeb yaj kiab tawv thiab pob tshab rau ntawm cov khoom ntawm cov khoom, nrog cov roj tsis taus thiab tiv thaiv cov khoom tiv thaiv zoo. Cov cuab yeej no ua rau nws siv dav hlau, tshuaj pleev tshuaj yeeb thiab lwm daim teb.
Nto Ua Si
HPMC muaj qhov zoo emulsification thiab tiv thaiv kev tiv thaiv kev sib xyaw, thiab muaj peev xwm txhim kho hauv Multiphase Systems, Li txhim kho cov kev sib xws thiab ruaj khov ntawm lub system.
2. HPMC Cov Txheej Txheem Ntau Lawm
Kev tsim khoom ntawm industrial industrial-qib HPMC tsuas yog suav nrog cov kauj ruam hauv qab no:
Raw Khoom Npaj
Siv cov khoom siv hauv xov xwm ntuj (paj rwb lossis ntoo lossis cov khoom siv raw, nws yog tso tawm hauv kev kho kom zoo nkauj kom nthuav dav thiab ua kom lub cellulose molecular molecular molecular molecular molecular molecular.
Etherification cov tshuaj tiv thaiv
Ntawm lub hauv paus ntawm cov neeg sawv cev alkalized, xws li cov tshuaj tiv thaiv methyl (xws li cov tshuaj tua kab mob methyl tau ntxiv, thiab lub siab kom tsim hydroxypropylencellulose.
Kev Kho Mob Tom Qab
Cov tshuaj tiv thaiv cov tshuaj tiv thaiv, ntxuav, kom qhuav thiab cov kauj ruam txheej txheem sib tsoo kom tau txais kev siv HPCosities sib txawv thiab ua raws li cov kev xav tau.
3. Cov ntaub ntawv thov loj ntawm HPMC
Kev Tsim Kho Kev Tsim Kho
HPMC yog ib qho tseem ceeb hauv cov tshuaj khib qhuav, cov hmoov av nplaum, ua kom muaj hmoov thiab dej tsis zoo. Nws cov dej ua tuab thiab ua kom muaj zog txhim kho kev tsim kho kev tsim kho, ua kom cov ntaub ntawv hauv tsev ntau ruaj khov thiab ua haujlwm yooj yim.
Tsho thiab xim av
HPMC tuaj yeem raug siv los ua cov tuab dua, dispersant thiab stabilizer nyob rau hauv cov txheej txheej los muab cov txheej txheej sib txawv, txhim kho kev txhuam hniav thiab txhim kho kev tiv thaiv kev ua haujlwm ntawm cov txheej txheem.
Kws muag tshuaj thiab khoom noj
Hauv kev lag luam kws tshuaj, HPMC feem ntau siv los npaj cov txheej txheem txheej thiab cov nplaum rau cov ntsiav tshuaj, thiab tseem siv rau kev tswj hwm kev tawm ntawm kev tso tawm. Hauv kev ua zaub mov noj, HPMC yog siv los ua emulsifier, thickener thiab stabilizer nyob rau ntau yam khoom noj.
Cov Tshuaj Txhua Hnub
HPMC yog dav siv nyob rau hauv cov tshuaj zawv plaub hau, cov khoom tu tawv nqaij thiab lwm yam khoom, muab cov teebmeem ruaj khov, ua kom zoo dua qub.
4. Cov txiaj ntsig thiab cov qauv kev txhim kho ntawm Industrial-Qib HPMC
Qhov Zoo
Industrial-Qib HPMC muaj kev nyab xeeb thiab ib puag ncig ua phooj ywg, muaj ntau yam ntawm cov peev txheej, thiab muaj ntau yam kev ua tau zoo. Nws tuaj yeem ua kom tau raws li qhov xav tau ntawm kev lag luam niaj hnub rau kev ua tau zoo, ntsuab thiab ntau yam khoom siv. Nyob rau tib lub sijhawm, nws cov kev siv yog me me tab sis cov nyhuv yog qhov tseem ceeb, thiab nws muaj tus nqi siab-ua tau zoo.
Kev Loj Hlob Qauv
Nrog rau kev txhim kho cov vaj tse ntsuab, ib puag ncig phooj ywg zoo thiab cov tshuaj high-aipect photo, qhov kev thov rau HPMC yuav loj hlob ntxiv. Nyob rau tib lub sijhawm, cov txheej txheem ntau lawm ntawm HPMC tau ua tiav ntawm kev ua haujlwm siab, tsawg noj thiab tsis muaj kuab paug, ntxiv kev pab nyiaj ntxiv thiab ib puag ncig.
Industrial-qib hydroxypropyl methylpcellulose tau dhau los ua qhov tsis tseem ceeb thiab tseem ceeb ib tug neeg sawv cev hauv kev lag luam nrog nws cov khoom siv lub cev thiab tshuaj zoo. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm thev naus laus zis thiab nthuav ntawm cov ntawv thov, kev lag luam kev cia siab ntawm HPMC yuav nthuav dav. Los ntawm kev tshawb fawb txuas ntxiv thiab kev tsim kho tshiab thiab kev ua haujlwm, nws txoj kev ua tau zoo ntxiv kom zoo ntxiv kom tau zoo dua li cov kev xav tau ntawm ntau yam kev lag luam.
