3. Txoj kev siv
Txoj kev yaj
Txoj kev faib dej txias: Maj mam muab HPMC nchuav rau hauv dej txias, do tas li kom txog thaum sib npaug zos, tom qab ntawd ua kom sov rau 30-60 ℃ thiab yaj tag.
Txoj kev yaj dej kub: ua ntej ntub HPMC nrog dej kub (saum toj no 60 ° C) kom nws o, tom qab ntawd ntxiv dej txias thiab do kom yaj nws.
Txoj kev sib tov qhuav: ua ntej sib tov HPMC nrog lwm cov hmoov qhuav, tom qab ntawd ntxiv dej thiab do kom yaj nws.
Tus nqi ntxiv
Hauv kev lag luam kev tsim kho, qhov ntxiv ntawm HPMC feem ntau yog 0.1% -0.5%.
Hauv kev lag luam khoom noj thiab tshuaj, qhov ntxiv ntxiv raug kho raws li lub hom phiaj tshwj xeeb.
4. Cov kev ceev faj rau kev siv
Cov xwm txheej cia khoom
Khaws cia rau qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo, tsis txhob muaj dej noo thiab tshav ntuj ncaj qha.
Khaws cia kom deb ntawm cov chaw kub, cov chaw hluav taws thiab cov tshuaj oxidants muaj zog kom tiv thaiv kev puas tsuaj thiab kev kub hnyiab.
Cov kev ceev faj rau kev yaj
Tsis txhob ntxiv ntau HPMC ib zaug kom tiv thaiv kev tsim cov pob thiab cuam tshuam rau qhov kev yaj.
Qhov ceev ntawm kev yaj qeeb hauv qhov chaw kub qis, thiab qhov kub tuaj yeem nce ntxiv kom haum lossis lub sijhawm nplawm tuaj yeem ntev dua.
Kev nyab xeeb ntawm kev siv
HPMC yog cov tshuaj tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij, tab sis nws yuav ua rau ua pa tsis taus thaum lub sijhawm ua hmoov, thiab yuav tsum zam kom tsis txhob muaj hmoov av ntau.
Nws raug pom zoo kom hnav lub npog ntsej muag thiab lub tsom iav thaum lub sijhawm tsim kho kom tsis txhob ua rau cov hmoov av khaus rau txoj hlab pa thiab qhov muag.
Kev Sib Haum Xeeb
Thaum siv, xyuam xim rau qhov sib xws nrog lwm cov tshuaj, tshwj xeeb tshaj yog thaum npaj cov ntaub ntawv tsim kho lossis tshuaj, kev sim sib xws yog qhov yuav tsum tau ua.
Hauv kev ua zaub mov thiab tshuaj, yuav tsum ua raws li cov cai thiab cov qauv tsim nyog kom ntseeg tau tias muaj kev nyab xeeb.
Hydroxypropyl methylcelluloseyog siv dav hauv ntau lub lag luam vim nws qhov kev ua tau zoo heev. Thaum siv, nws yog qhov tsim nyog los tswj hwm txoj kev yaj thiab kev siv kom raug, thiab them sai sai rau kev khaws cia thiab kev nyab xeeb kom ntseeg tau tias cov khoom ruaj khov thiab kev ua tau zoo. Kev siv HPMC kom raug tsis tsuas yog tuaj yeem txhim kho cov khoom zoo, tab sis kuj txhim kho kev ua haujlwm ntawm kev tsim kho thiab kev tsim khoom.
