MC Kazhinji, iyo degree rekutsiva ndeye 1.6 ~ 2.0, uye iyo solubility yakasiyana nemadhigirii akasiyana ekutsiva. Izvo ndezvevasina-ionic cellulose ether.
. Kazhinji, kana huwandu hwehuwandu hwakakura, hushoma hushoma, uye visikoka yakakura, iyo mwero wekuchengetwa kwemvura wakakwira. Pakati pavo, huwandu hwekuwedzera hunonyanya kuitwa pane iyo yekuchengetwa kwemvura, uye mwero weViscosity haina kuenzana zvakananga kusvika padanho rekuchengetera mvura. Iyo yekunyungudika chiyero inonyanya kuenderana neiyo degree rekushandurwa kwepasi kweCellulose zvimedu uye tangi. Pakati peiyo metherulose methelose erinculose uye methyl cellulose uye hydroxyprusll
(2. Mhinduro yaro yemvura yakagadzikana kwazvo mune huwandu hwePH = 3 ~ 12. Iyo ine kuwirirana kwakanaka ne starch, guar gum, nezvimwewo uye vazhinji surfachan. Kana tembiricha ichisvika kumhepo tembiricha, gelation inoitika.
. Kazhinji, kukwirira kwakanyanya, kwakaipisisa kuchengetwa kwemvura. Kana tembiricha inovhuvhuta 40 ° C, kuchengetwa kwemvura methyl cellulose kuchave kuderedzwa zvakanyanya, kukanganisa zvakanyanya kuvakwa kwemutya.
. "Kunamatira" pano kunoreva kushushikana kwakanzwika pakati peiyo mushandi weMushandi weMushandi uye substrate, kureva kuti, iyo Shear Ristance yerudzi. Kunamatira kwakakwira, kurwisa Shefu kwakakura kwakakura, uye simba rinodiwa nevashandi vari mukati mekushandiswa kwakakura zvakare, uye kuita kwekuvaka kune murombo. Methyl Cellulose Adernan iri pane imwe nhanho pakati mu cellulose ether zvigadzirwa.
HPMC ndeye hydroxypropyl methylcellose, iyo isiri-ionic cellulose yakavhenganiswa kubva kuCotton yakanatswa mushure mekunge methyl Iyo degree rekutsiva kazhinji 1.2 ~ 2.0. Zvivakwa zvaro zvakasiyana nekuda kweiyo dzakasiyana ratios ye metroxls zvemukati uye hydroxypruppropyl zvemukati.
(1. Asi tembiricha yayo yegungwa mumvura inopisa yakakwirira zvakanyanya kupfuura iyo ye methyl cellulose. Iyo solubility mumvura inotonhora inovandudzwa zvakare yakaenzaniswa ne methyl cellulose.
. Tembiricha inokanganisawo zvavakaita, sekuwedzera kwekuwedzera, viscosity inoderera. Nekudaro, viscosity yakakwira ine yakaderera tembiricha mari pane methyl cellelose. Kugadziriswa kwayo kwakasimba kana kuchengetwa pamhepo tembiricha.
. Caustic soda uye lime mvura ine zvishoma kushanda pane zvayo kuita, asi Alkali inogona kukurumidza kukurumidza kupaza uye kuwedzera zvavakaita. Hydroxyprupyl methylcellose yakachengetwa kune zvakajairika kumaronda, asi kana kusungwa kwemhinduro kwakakwirira, iyo visikopa yehydroxyproslose mhinduro inowanzowedzera kuwedzera.
.
. Senge polyvinyl doro, starch ether, miriwo gamu, nezvimwe.
