Nws muaj zoo moisturizing thiab stabilizing zog, txhim kho cov khoom siv kev paub.
Lwm yam kev lag luam siv
Nws yog siv los ua thickener, nplaum los yog emulsifier hauv ceramics, textiles, papermaking, inks, tshuaj tua kab thiab lwm yam lag luam.
3. Txoj kev siv
Txoj kev tawg
Txoj kev sib cais dej txias: Maj mam nphoo HPMC rau hauv dej txias, do tsis tu ncua kom txog thaum sib sib zog nqus, ces kub rau 30-60 ℃ thiab yaj tag.
Txoj kev daws dej kub: thawj zaug moisten HPMC nrog dej kub (siab tshaj 60 ° C) kom nws o, ces ntxiv dej txias thiab do kom dissolve nws.
Kev sib xyaw qhuav: thawj zaug sib xyaw HPMC nrog lwm cov hmoov qhuav, tom qab ntawd ntxiv dej thiab do kom yaj.
Ntxiv tus nqi
Hauv kev tsim kho kev lag luam, qhov sib ntxiv ntawm HPMC feem ntau yog 0.1% -0.5%.
Hauv kev lag luam khoom noj thiab tshuaj, qhov sib ntxiv yog hloov raws li lub hom phiaj tshwj xeeb.
4. Ceev faj rau kev siv
Cia tej yam kev mob
Khaws rau hauv qhov chaw txias, qhuav, zoo-ventilated, tsis txhob ya raws thiab tshav ntuj ncaj qha.
Khaws kom deb ntawm qhov chaw tshav kub, qhov hluav taws kub thiab muaj zog oxidants los tiv thaiv degradation thiab combustion.
Kev ceev faj rau kev tawg
Tsis txhob ntxiv ntau ntawm HPMC ib zaug los tiv thaiv kev tsim cov lumps thiab cuam tshuam rau cov nyhuv dissolution.
Lub dissolution ceev yog qeeb nyob rau hauv ib tug tsawg kub ib puag ncig, thiab qhov kub thiab txias yuav tsum tsim nyog nce los yog lub sij hawm stirring yuav txuas ntxiv.
Kev nyab xeeb ntawm kev siv
HPMC yog ib yam khoom uas tsis muaj tshuaj lom thiab tsis muaj teeb meem, tab sis nws yuav ua rau kom nqus tau pa hauv cov hmoov av, thiab cov hmoov av ntau yuav tsum raug zam.
Nws raug nquahu kom hnav lub npog ntsej muag thiab tsom iav thaum lub sijhawm tsim kho kom tsis txhob muaj plua plav ua rau lub ntsws thiab qhov muag.
Kev sib haum xeeb
Thaum siv, xyuam xim rau kev sib raug zoo nrog lwm yam tshuaj, tshwj xeeb tshaj yog thaum npaj cov khoom siv hauv tsev lossis tshuaj, yuav tsum tau kuaj xyuas kev sib raug zoo.
Hauv kev ua zaub mov thiab tshuaj, cov kev cai thiab cov qauv tsim nyog yuav tsum tau ua kom muaj kev nyab xeeb.
Hydroxypropyl methylcellulose yog sivyog dav siv nyob rau hauv ntau industries vim nws cov kev ua tau zoo heev. Thaum siv, nws yog ib qho tsim nyog yuav tsum tau ua kom tiav txoj kev sib cais kom raug thiab kev siv cov txuj ci, thiab xyuam xim rau kev khaws cia thiab kev nyab xeeb teeb meem kom ntseeg tau tias kev ruaj ntseg thiab kev ua haujlwm ntawm cov khoom. Kev siv HPMC tsis yog tsuas yog txhim kho cov khoom zoo, tab sis kuj txhim kho kev tsim kho thiab kev tsim khoom.
