Hydroxypropyl methylcellulose (HPMC) i cellulose ether isinganyunguduke mumvura inoshandiswa zvakanyanya mukuvaka, mishonga, chikafu, zvizoro uye makemikari. Hunhu hwe viscosity yemvura yayo ndiyo zvinhu zvikuru zvinokanganisa mashandiro ayo.
1. Hunhu hwekutanga hweHPMC
AnxinCel®HPMC chinhu chinobva mu cellulose chinogadzirwa nekupinza hydroxypropyl ne methyl groups mu molecular chain ye cellulose. Ine mvura inonyunguduka zvakanaka uye ine viscosity yakakwira, uye inowanzoshandiswa kugadzira mvura ine hunhu hwakasiyana hwe rheological. Hunhu uhwu hunoita kuti HPMC ishandiswe zvakanyanya mu coatings, glues, drug release, food additives nedzimwe nzvimbo dzeindasitiri.
2. Hunhu hweHPMC yemvura ine viscosity
Hunhu hwekusviba kwemvura yeHPMC hunokanganiswa nezvinhu zvakawanda, zvinosanganisira kuwanda kwayo, tembiricha, mwero wekuchekwa kwayo, pH kukosha kwayo uye chimiro chemorekuru.
Mhedzisiro yekuisa pfungwa pa viscosity
Kuwanda kwemvura yeHPMC kunowedzera nekuwedzera kwehuwandu hwemvura. Kana huwandu hweHPMC huri pasi, mvura inobuda muropa inova diki uye ine kuwanda kushoma; sezvo huwandu hunowedzera, kudyidzana pakati pemamorekuru kunowedzera, uye kuwanda kwemvura kunowedzera zvakanyanya. Kazhinji, kuwanda kwemvura yeHPMC kunoenderana zvakanyanya nekuwanda kwayo, asi inowanzova yakagadzikana pane imwe kuwanda, ichiratidza hunhu hwemvura inobuda muropa.
Mhedzisiro yekupisa pa viscosity
Kupisa chinhu chakakosha chinokanganisa kusimba kweAnxinCel®HPMC aqueous solution. Sezvo tembiricha ichikwira, mahydrogen bonds uye hydrophobic interactions mumamorekuru eHPMC zvinopera simba, zvichikonzera kudzikira kwesimba rekubatana pakati pemamorekuru, nokudaro zvichideredza kusimba kwemvura. Kazhinji, kusimba kweHPMC aqueous solution kunoratidza kudzikira kukuru nekuwedzera kwekupisa, kunyanya muhuwandu hwekupisa hwakakwira. Hunhu uhwu hunoita kuti HPMC ive nekugona kuri nani kudzora mune mamwe mashandisirwo ekudzora tembiricha.
Mhedzisiro yehuwandu hwekuchekwa kwebvudzi pa viscosity
Mhinduro yemvura yeHPMC inoratidza hunhu hwemvura yeNewtonian pahuwandu hwakaderera hwekuchekwa, kureva kuti, viscosity yakagadzikana; zvisinei, pahuwandu hwakanyanya hwekuchekwa, viscosity yemhinduro yeHPMC ichaderera zvakanyanya, zvichiratidza kuti ine hunhu hwekuchekwa kweganda. Mamorekuru eHPMC ane hunhu hwakati wandei hwerheological. Pahuwandu hwakaderera hwekuchekwa, mamorekuru anokombama zvakanyanya, zvichiita kuti pave nekuramba kwakakwirira, izvo zvinoratidzwa sekusimba kwakakwira; pahuwandu hwakanyanya hwekuchekwa, mamorekuru anotambanuka, kuyerera kweganda kunowedzerwa, uye viscosity inoderera.
Mhedzisiro ye pH kukosha pa viscosity
Mhinduro yemvura yeHPMC inowanzo chengetedza viscosity yakagadzikana pasi pemamiriro ealkaline asina kusimba. Munzvimbo ine acid yakasimba kana yakasimba, mamorekuru eHPMC anogona kuita protonation kana deprotonation reactions, zvichikonzera shanduko mu hydrophilicity, hydrophobicity uye intermolecular interactions pakati pemamorekuru, nokudaro zvichikanganisa viscosity yemvura. Mumamiriro ezvinhu akajairwa, shanduko mu pH hadzina simba guru pa viscosity ye HPMC solutions, asi pasi pemamiriro e pH akanyanya, shanduko ye viscosity inogona kuve pachena.
Mhedzisiro yechimiro chemamorekuru pa viscosity
Hunhu hweHPMC hwekusviba hunoenderana zvikuru nechimiro chayo chemamorekuru. Mwero wekutsiva hydroxypropyl ne methyl groups mumorekuru une simba guru pakusviba kwemvura. Mwero wekutsiva weboka racho wakakwira, kusviba kwe HPMC kunowedzera uye kusviba kwemvura kunowedzera. Pamusoro pezvo, huremu hwe HPMC hwemamorekuru chinhu chakakosha chinokanganisa kusviba kwayo. Kurema kwemorekuru kwakakura, kurebesa kwecheni yemamorekuru, uye kusimba kwekudyidzana pakati pemamorekuru, zvichikonzera kusviba kwakanyanya kwemvura.
3. Kukosha kwehunhu hwe viscosity hwe HPMC yemvura mhinduro mukushandiswa
Hunhu hwekusviba kwemvura yeHPMC hwakakosha pakushandiswa kwayo muminda yakasiyana-siyana.
Nzvimbo yekuvaka: HPMC inowanzoshandiswa mumota nesimende uye zvinonamatira, uye ine mabasa ekukora, kuchengetedza hunyoro, uye kuvandudza mashandiro ekuvaka. Hunhu hwayo hwekusimba hunokanganisa zvakananga kushanda uye kunamira kwemota. Nekugadzirisa huwandu uye chimiro chemamorekuru eHPMC, hunhu hwerheological hwemota hunogona kudzorwa, nokudaro zvichivandudza nyore kwekuvaka.
Indasitiri yeMishonga: AnxinCel®HPMC mvura inobuda mumishonga inowanzo shandiswa mukugadzira mishonga yakadai semishonga inoburitsa mishonga kwenguva refu, macapsule shells, uye madonhwe emaziso. Hunhu hwayo hwekusviba hunogona kukanganisa huwandu hwekuburitswa kwemishonga uye kudzora maitiro ekuburitswa kwemishonga mumuviri. Nekusarudza HPMC nehuremu hwakakodzera hwemamorekuru uye mwero wekutsiva, hunhu hwekuburitswa kwemishonga hunogona kugadziriswa kuti uwane mhedzisiro chaiyo yekurapa.
Indasitiri yezvekudya: HPMC inoshandiswa sechinhu chinosimbisa, chinosimbisa, uye chinosanganisa chikafu mukugadzira chikafu. Hunhu hwe viscosity yemvura yayo inokanganisa kuravira uye kugadzikana kwechikafu. Nekugadzirisa mhando nehuwandu hweHPMC inoshandiswa, magadzirirwo ezvekudya anogona kudzorwa nemazvo.
Indasitiri yezvekushongedza: HPMC, semuchina wekuomesa uye wekusimbisa muzvekushongedza, inogona kuvandudza magadzirirwo echigadzirwa, ichichipa kuyerera kwakakodzera uye kunzwa kwakanaka. Hunhu hwayo hwekupenya hune simba guru pakushandiswa kwezvigadzirwa zvakaita semakirimu, majeli, uye mashampoo.
Hunhu hwe viscosityHPMC Mhinduro dzemvura dzinokanganiswa nezvinhu zvakawanda zvakaita sekuwanda kwemvura, tembiricha, mwero wekuchekwa kwemvura, pH, uye chimiro chemamorekuru. Nekugadzirisa zvinhu izvi, mashandiro eHPMC anogona kugadziriswa kuti asvike kune zvinodiwa nemaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hwe rheological. Tsvagiridzo yakadzama pamusoro pehunhu hwe viscosity hwemhinduro dzemvura dzeHPMC haingobatsiri chete kunzwisisa hunhu hwayo hwepakutanga, asiwo inopa nhungamiro yedzidziso yekushandiswa kwayo mukugadzirwa chaiko.
