MC Kazhinji, iyo degree rekutsiva ndeye 1.6 ~ 2.0, uye iyo solubility yakasiyana nemadhigirii akasiyana ekutsiva. Ndezvekuti zvisiri-ionic cellulose ether.
(1) Kuchengeta kwemvura kwemethyl cellulosezvinoenderana nehuwandu hwayo hwekuwedzera, viscosity, chetatu deseness uye kupaza mwero. Kazhinji, kana huwandu hwekuwedzera hwakakura, hushoma hushoma, uye visikoka yakakura, iyo mwero wekuchengetedza mvura wakakwira. Pakati pavo, huwandu hwekuwedzera hune simba rakakura pane imwe nguva yekuchengetedza mvura, uye mwero weViscosity haina kuenzana kusvika padanho rekuchengetwa kwemvura. Iyo yekunyungudika chiyero inonyanya kuenderana neyero yekugadziridzwa kwepasi kweiyo cellulose zvimedu uye zvakajeka zvezvikamu. Pakati peiyo metherulose methelose erinculose uye methyl cellulose uye hydroxyprusll
(2. Iyo ine kuwirirana kwakanaka ne starch, guar gum, nezvimwewo uye vazhinji surfachan. Kana tembiricha ichisvika tembiricha yegungwa, chiitiko chegwenzi chinoitika.
. Kazhinji, kukwirira kwakanyanya, kwakaipisisa kuchengetwa kwemvura. Kana tembiricha inovhuvhuta 40 ° C, kuchengetwa kwemvura methyl cellulose kuchave kwakaipisisa, uko kuchakanganisa zvakanyanya kushanda kwemutya.
. "Kunamatira" pano kunoreva kuti kushamwaridzana kwakanzwa pakati peiyo mushandi wechisimba mudziyo uye substrate, kureva rwiyo rwehasha. Kudonha kwakakura, kupokana naSheura kwakakura kwakakura, uye simba rinodiwa nevashandi vacho vari mukushandiswa kwakakura zvakare, uye kuvakwa kwemutya kune murombo. MetHylcellose Adernon iri pane imwe nhanho ine mwero mu cellulose ether zvigadzirwa.
HPMC ndeye hydroxyprusyl methyl cellel celler Iyo degree rekutsiva kazhinji 1.2 kusvika 2.0. Zvivakwa zvayo zvinosiyana zvichienderana nehuwandu hwezvemukati zvemukati uye hydroxypruppropyl zvemukati.
(1. Asi tembiricha yayo yegungwa mumvura inopisa yakakwirira zvakanyanya kupfuura iyo ye methyl cellulose. Kupararira kwemvura inotonhora kunovandudzwa zvakare kwakaenzaniswa nemethyl cellulose.
. Tembiricha inokanganisawo zvavakaita, sekuwedzera kwekuwedzera, viscosity inoderera. Asi viscosity yayo haina kunyatso kukanganiswa nekudziya kwakanyanya kupfuura methyl cellelose. Kugadziriswa kwayo kwakasimba pakuchengetedza pamhepo tembiricha.
. Caustic soda uye lime mvura ine zvishoma kushanda pane zvayo kuita, asi Alkali inogona kukurumidza kukurumidza kupaza uye kuwedzera viscosity. Hydroxyprupyl methylcellose yakagadzikana kune zvakajairwa nemaronda, asi kana kusungwa kweSalm Solution kwakakwira, iyo visikopo yeiyo hydroxyprosyl mhinduro inowanzowedzera kuwedzera.
(4) Kuchengeta kwemvurahydroxypruppropyl methylcellosezvinoenderana nehuwandu hwayo hwekuwedzera, viscosity, etc. iyo yemvura yekuchengetedza mvura pasi peiyo imwe yekuwedzera huwandu hwakakwira kupfuura iro reMethyl Cellulose.
. Senge polyvinyl doro, starch ether, miriwo gamu, nezvimwe.
