Iyo yakakura iyo viscosity yeHpcHydroxyprirpropyl methyl cellelose, zviri nani kudzokorora kwemvura. Viscosity izimendi yakakosha yeHPMC kuita. Parizvino, akasiyana HPMC Vagadziri vanoshandisa nzira dzakasiyana uye zviridzwa kuti vaone viscosity yeHPMC. Nzira huru nzira dziri kuregera Rotosko, hoppler, ubbelohde neBrookfield, nezvimwe.
Nezve chigadzirwa chimwe chete, mhedzisiro yeViscosity yakayerwa nenzira dzakasiyana dzakasiyana-siyana dzakasiyana, mamwe atova misiyano yakawanda. Naizvozvo, patinofananidza viscosity, inofanira kuitwa pakati penzira imwecheteyo yekuedzwa nzira, kusanganisira tembiricha, rotaricha, etc.
Yehukuru hwechikamu, iyo yakanakisa iyo tangi, iri nani kuchengetwa kwemvura. Zvikuru zvevakakura zve Cellulose Elether kusangana nemvura, pamusoro pazvo pakarepo kuputira mamorekuru, dzimwe nguva nguva yekudzvinyirira haina kunyorwa, kuumbwa kweiyo madhaka fletuclent kana agglomerate. Iyo solubility ye cellulose ether ndiyo imwe yezvinhu kusarudza cellulose ether. Fineness zvakare ndiyo yakakosha performance index ye methyl cellelose ther. MC yeMutungamiriri akaoma inoda poda, yakaderera mvura zvemvura, uye yakajeka ye20% ~ 60% timende saizi isingasviki 63um. Finess inokanganisa iyo solubility yeHpchydroxypruppropyl methyl cellelose ether. Coarte mc inowanzo kuvezwa nemvura isina kuhukura mumvura pasina chinoshungurudza, asi kumhanya kwekunyungudika kunononoka, saka hazvina kukodzera kushandiswa mune yakaoma dhiri. Mune yakaoma Dor Kana MC inowedzera mvura kuti isimbe agglomerate, yakaoma kwazvo kuparadzira uye ichinyungudika. MC neCoarse yakajeka kwete chete marara, asi zvakare inoderedza simba remunharaunda yemotokari. Kana duku rakaoma kudaro rakagadzirwa munzvimbo yakakura, kurapa kwekurapa kwemutya wemuno kuderedzwa kwakanyanya kuderedzwa, zvichikonzera kupaza kwakakonzerwa nekuporesa kwakasiyana. Kune muchina wekupfira mucheka, nekuda kwenguva pfupi yekusanganisa, iyo yakanaka yakakwira.
Kazhinji, iyo yepamusoro viscosity, iri nani kuchengetedza kwemvura. Nekudaro, iyo yepamusoro iyo viscosity iri, iyo yepamusoro suremu hweMC ndeye, uye kuita kwekunyungudza kuchadzikira kunoenderana, uko kunokanganisa kusimba uye kuita kwekuvaka kwemota. Iyo yepamusoro viscosity, zvakanyatsojeka mhedzisiro yemota, asi haina kuenzana neukama. Yakakwira viscosity, iyo mongwe yakanyorova ichave inonamira, zvese zvekuvakwa, kuita kweiyo inonamira scriper uye yakanyanya kuderedza kune iyo base. Asi hazvibatsiri kuwedzera simba rekuumbwa renyama rakanyorova. Munguva yekuvaka, kuita kwekurwisa-sag hakusi pachena. Kusiyana neizvozvo, imwe viscosity yakaderera asi yakagadziridzwa methyl cellel cellulose mashandiro akanaka mukuvandudza simba rerudzi rwemutengesi.
Iyo yakawanda cellulose ether inowedzerwa kune durari, iyo iri nani mvura yekuchengetedza, yakakwira viscosity, iyo iri nani yekuchengetedza mvura yekuita.
Hpmc Chikuru Chimwezve chine chekuita nekuchengetwa kwemvura, kazhinji kutaura, kune iwo maViscosity imwe chete yeMethyl Cellalose Erthero, mune iyo yakaenzana yekuwedzera mari iri nani.
Kuchengetwa kwemvura kweHPMC kunoenderana ne tembiricha yekushandisa, uye kuchengetwa kwemvura methyl cellulose theri kuderera nekukwira kwekushisa kwekushisa. Asi mune chaicho chinhu chekushandisa, nzvimbo dzakawanda dzemutooma dzakaoma dzinowanzove mukupisa kwakanyanya (yakakwirira madhigirii ekuvakira madziro ekunze Kuderera kwehuwandu hwekuchengetwa kwemvura kunotungamira kumanzwiro ari pachena kuti zvese zvinovaka uye kupaza kuramba kwakanganiswa. Mumamiriro ezvinhu aya, kuderedza pesvedzero yezvinhu zvekushisa zvinonyanya kutsoropodza. Kunyangwe iyo yekuwedzera kwe methyl hydroxyll cellethyl cellylose ether inoonekwa seyakavambwa zvekusimudzira tekinoroji, kutsamira kwaro kuchiri kutungamira mukushayiwa kwezvinhu zvakaoma. Kunyangwe nekuwedzera kwemethyl hydroxyl cellenyl cellenlose dosage (zhizha formula), kuvaka uye kupaza kuramba kuchiri kugona kuzadzisa zvinodiwa. Kupfuura kumwe kurapwa kwakakosha kweMC, sekuwedzera mwero wekutsvaira, kudzokorora kwemvura kweMC kunogona kuchengetedza maitiro ari nani pasi pekushisa kwakanyanya, kuitira kuti zvive zvinofanirwa kupa zviri nani mamiriro ezvinhu ane hutsinye mamiriro ezvinhu.
