HydroxyPropyl methyl celler HPMC ndeye isiri-ionic cellulose inosanganiswa ine akasiyana-siyana uye ionic methym carbolethlet ether, hazviite nemitezo inorema. Imwe okisijeni radicals nekuda kwe hydroxyprupyl methyl methlose cellyl cellowr Iko kuita kuri padyo neiyo hydroxyprupyl methyl cellelose kunogadzirwa. Asi mune dzakasiyana siyana, kunyangwe iine chete huwandu hwe hydroxpropropyl kana diki yeiyo nzira, iyo solubility mu organic sol sol solution mhinduro, pane mutsauko mukuru.
1, hydroxyprupyl methyl cellelose solubility
HydroxyPropyl methyl cellel cellulose ye hydroxpropyl methyl cellyl cellyl cellevyl cellyl cell Nekudaro, tembiricha yegungwa yeiyo yakagadziridzwa hydroxy yakakwira yakawanda kupfuura iyo yeMethyl Cellulose mumvura inopisa. Semuenzaniso, iyo viscosity ye hydroxypropyl methylcellose mhinduro ine 2% nzira yezvinyorwa DS = 0.73 uye hydroxprepropyl Zvemukati ms = 0.46 ndeye 500 mpa na20 ℃. Iyo tembiricha yechigadzirwa yechigadzirwa iri padyo ne100 ℃, nepo iyo methyl cellulose yekupisa kumwe chete ingangoita chete 55 ℃. Kana ari salubility mumvura, semuenzaniso, mushure mekupwanya kwehydroxyprosyl metdlcellose (gadzira-ema 20 pita
. " Viscosity HydroxyPropyl methyl Cellelose neyekutsiva degree pamusoro pe1.0 Izvo zvakare zvinyoro-nyoro muhukunzi yehydrocarbons senge Dichlomethane, uye organic soloms yakadai seacetone, isopropyl doro, uye diacetone doro. Yayo solubility mu organic sols yakakwirira kune mvura solubility.
2, hydroxyprupyl methyl cellalose viscosity yekukuvara zvinhu
Hydroxyprusyl methylcellose viscossulose zvinhu Hydroxyprosyl metdropyl metroslese standslceulose kutsunga, uye mamwe cellulose ether yakafanana, ari pamakumi maviri nemakumi maviri emvura yekutsanangurwa kwekutsanangurwa. Iyo viscosity yakafanana nechigadzirwa chimwe chete, nekuwedzera kwekuwedzera uye kuwedzera, iyo yakafanana yekushambadzira yemasero yakasarudzika yehuremu hwezvigadzirwa, uremu hwechigadzirwa hombe dzisimusi viscosity. Hukama hwayo nekushisa hwakafanana neye methyl cellulose. Kana tembiricha ikawasuka, visikoka inotanga kuderera, asi kana ichisvika pane imwe tembiricha, iyo visikoka yakangoerekana yasimuka uye gelation inoitika. Iyo tembiricha yemhepo yezvigadzirwa neyakaderera viscosity yakakwira kupfuura iyo yezvigadzirwa neyekutanga viscosity. Iyo nhanho yeiyo gel point, kuwedzera kune yakakwirira uye yakaderera viscosity ye ether, asi zvakare ine ether maitiro uye hydroxyprosproproposition ratio uye huwandu hwakazara hwekutsiva hwakabatana. Izvo zvinofanirwa kucherechedzwa kuti hydroxyprupropyl methylcellose zvakare pseudoplastic; Kugadziriswa kwayo kwakachengetwa kana kuchengetwa pamhepo tembiricha uye hakuratidze chero kushomeka kwe viscossity kunze kwekuti mukana wekusvibiswa kwe enzymatic.
3, hydroxyprusyl methyl cellelose acid uye alkaline kuramba
HydroxyprEpyl methylcellulose Acdliese Acdroxpropylpropropyl acid ine mhedzisiro yekuderedza iyo viscosity. ALKALI SEZVASHURE SODAT, CAUSTIC Potassium uye Lime mvura haina mhedzisiro pazviri, asi mhedzisiro yekuwedzera zvishoma zvevisiko yemhinduro ichaderera zvishoma mune ramangwana.
4, hydroxypruppropyl methyl cellulose inogona kusanganiswa
HydroxyPropyl methyl celler Solulose Solution inogona kusanganiswa neye-soluble polymer makomputa, uye iva yunifomu yekufungidzira mhinduro ine yepamusoro yepamusoro. Iyi yakakwira makomputa iri polyethyl, polyvinyl acetate, polysilicone HydroxyPropyl methyl methyl celler inogona zvakare kusanganiswa neyekuba acid kana palmitical acid
5, hydroxyprupyl methyl cellelose insoluble mvura inokwira
HydroxyPropyl methyl cellel Cellelose insoluble mvura-solulle cell Uye ita hydroxyprusylmyl methylcellose insoluble aldehyde, Glyoxal, etcelyde Iyo Dosage yerudzi urwu rwekuyambuka mumiririri ndeyekugadziriswa ndeye 0.2% ~ 10% yegumi ne7% ~ Iyo general kurapwa tembiricha iri 0 ~ 30 ℃, nguva iri 1 ~ 120min. Iyo yekuyambuka-kuunganidza maitiro inoda kuitwa pasi pemamiriro ezvinhu emazwi. Kazhinji, inorganic yakasimba acid kana organic carboxylic acid inowedzerwa kune iyo mhinduro yekugadzirisa iyo mhinduro kune 2 ~ 6, uyezve aldehs dunhu rakawedzerwa rekubatanidza maitiro. Iyo Acids inoshandiswa ndeye hydrochloric acid, sulfuric acid, phosphoric acid, acid acid, pakati peiyo acid acid ndiyo yakanyanya kunaka, nepo mafomu acid ndiyo yakanyanya kunaka. Acids uye aldehydes inogona zvakare kuwedzerwa panguva imwe chete yekubvumira mhinduro yekuyambuka-yakabatanidzwa mune inodiwa pH range. Kuita uku kunowanzoshandiswa mune yekupedzisira maitiro e cellulose gadziriro yekugadzirira, saka iyo cellulose ether haina kunyungudusa, nyore kushandisa 20 ~ 25 ℃ mvura yekugeza nekushambidza. Kana chigadzirwa chishandiswe, maAlkaline zvinhu zvinogona kuwedzerwa kune iyo mhinduro yechigadzirwa kuti gadzirise iyo pH yemhinduro yekuve alkaline, uye chigadzirwa chinokurumidza kunyungudika mumhinduro. Iyi nzira inogona kushandiswawo kana cellulose ether solution inoshandiswa kugadzira firimu uye ipapo iyo firimu iri kurapwa kuti iite firimu risinganzwisisike.
6, hydroxyprupyl methyl cellelose anti-enzyme
Hydroxyprusyl methyl celler enzyme kurwisa cellerms inopfuura neyekutsiva mapoka, zvakare nekushambadzira kweGroughme Kwete yunifomu, hutachiona hunogona kukanganisa pedyo neasina kudzvanywa mapoka eglucose kuti aumbe mashuga, izvo zvinogona kubatikana nehutachiona sechikafu. Naizvozvo, kana iyo ertifitation kutsiva kwemasero inowedzera, kupokana kwemasero ether kusvika kuEnzymatic kurongeka kuchavandudzwa. Izvo zvinotaurwa kuti pasi pemamiriro ezvinhu anodzorwa, iyo viscosity ye hydroxypropyl methyl cellyl cellose (2.83), Hydroxyprusyl methyl cellelose ine yakasimba anti-enzyme kugona. Nekudaro hydroxyprupylpropyl methylcellose Intillose Anti-Enzyme, yakasanganiswa nekupararira kwayo, kuumbwa uye kuumbwa kwemhirizhonga, etc., kazhinji haidi kuwedzera kuchengetedza kuchengetedza. Nekudaro, kuitira kudzivirira kuchengetedza kwenguva refu kwemhinduro kana kusvibiswa kubva kune kunze kwenyika, kuchengetedza kunogona kuwedzerwa, kusarudza kwakasarudzika kunogona kutsanangurwa maererano nezvinodiwa zvekupedzisira zvemhinduro. Phenylmercuric acetate uye manganse fluosilte inoshanda inochengetedza, asi ivo vane chepfu uye vanofanirwa kunyatsoitwa. Kazhinji, 1 ~ 5mg phenylmercuric acetate inogona kuwedzerwa kune imwe neimwe liter yemhinduro.
7, hydroxyprupyl methyl cellose membrane performance
HydroxyPropyl methyl Celler Celler Performance yeHydroxyprEpropyl methyl Cellyl Celler Solution, yakaiswa pamusara wegirazi Iyo ine yakanaka yekunyorova kupokana uye inoramba yakasimba pakupisa kwakanyanya. Kufanana nekuwedzera kwehygroscopic plasticbec, kunogona kuwedzera kuwedzera kwayo uye kunatsiridza, kuti uve nejira uye glycrol uye sorbitol uye zvimwe zvakapetwa zvakanyanya. Iyo General Solution Kukurukurirana ndeye 2% ~ 3%, iyo plasticzer dosage iri 10% ~ 20% ye cellumolose ether. Kana zvirimo zvepapurasitiki zvakafanira, chinyoronyoro hwesimba rekusviba kwemvura rinogona kuitika mukunyorova kwakanyanya. Simba refirimu rakawedzera plasticzezer yakakura kupfuura iyo isina kuwedzerwa, uye inowedzera nekuwedzera kwehuwandu hweiyo firimu inowedzerawo nekuwedzera kwehuwandu hweplasticze.
