HydroxyPropyl methyl cellel cellowr rudzi rwe isiri-ionic cellyl caryl carbolethyl carbolethyl consbolethyl Nekuda kweiyo marodhi akasiyana ezvemukati uye hydroxyprupyl zvemukati muHydroxypropyl methylceose, semuenzaniso, yakakwira nzira, uye marudzi akadzika ane methyl cellyl Zvemukati, kuita kwayo kuri pedyo neiyo yehydroxypruppropyl methylcellose. Nekudaro, mumhando dzakasiyana-siyana, kunyangwe chete huwandu hushoma hwe hydroxpropyl group kana huwandu hwechishoma hwechikwata chirimo, iyo solubility sol sol sol solution mumamiriro ekunze akasiyana.
1. Iyo solubility ye hydroxypropyl methylcellose
①solubility of hydroxypropyl methyl methlose muchinwiwa methyropropyl methyl cellowlose cellyl cellyl cellyl Cellulose yakafanana mune inotonhora mvura solubility uye mvura inopisa insoxubility. Nekudaro, nekuda kweiyo yakagadziridzwa hydroxyprupropropyl boka, tembiricha yayo yekupisa mumvura inopisa yakakwira zvakanyanya kupfuura iyo yemethyl cellulose. Semuenzaniso, iyo viscosity yemvura mhinduro ye hydroxypropyl methylcellose ne 2% methyl Tembiricha yayo Gel inogona kusvika pedyo ne100 ° C, nepo methylcellose pakudziya kumwechete kungangoita chete 5 55 ° C. Kana ari solubility yayo mumvura, yakagadziridzwa kwazvo. Semuenzaniso, iyo polviised hydroxyprupyl methylcellose (granular chimiro che2,2 ° COACE SUPLE SOPOCK SOPE to 2PA?
②Tobility ye hydroxyprusyl methyl methlose musangano weiyo hydroxose HydroxyPropyl ms = 1.5 ~ 1.8 uye methy ds = 0.2 ~ 1.0, uye yakazara sceighm Izvo zvakare zvinyoro-nyoro muhukunini yehydrocarbons yakadai se dichlommethane uye chloroform, uye mune organic sol sol sol sol sol sol soldone, isopropanol uye diacetone doro. Yayo solubility mu organic sols iri nani pane mvura-soluble.
2. Zvinhu zvinokanganisa vhiza ye hydroxyprusypropyl methylcellose
Kufurira zvinhu zve hydroxyprupyl methyl celler cellowing kutsika kweiyo hydroxospropropyl methyl methyl cell Iyo viscosity yechigadzirwa chimwe chete ichiwedzera nekuwedzera kwekuwedzera. Zvezvigadzirwa zvine uremu hwakasiyana-soro pamwero wakaenzana, zvigadzirwa zvine huremu hukuru hwemanyorerwe zvine huwandu hwepamusoro tiscosity. Hukama hwayo nekushisa hwakafanana neye methyl cellulose. Kana tembiricha ikawedzera, viscosity inotanga kuderera, asi kana ichisvika pane imwe tembiricha, iyo visikoka kamwe kamwe inowedzera uye gelation inoitika. Tembiricha yegwenzi yezvigadzirwa zvepasi-zveviscossity yakakwira. yakakwira. Pope its Gel haina hukama chete neiyo visikoka yeEther, asi zvakare kune iyo kuumbwa kweiyo nzira uye hydroxypruppropyl mune ether uye huwandu hwakazara hwekutsiva. Izvo zvinofanirwa kucherechedzwa kuti hydroxyprupyl methylcellose zvakare pseudoplastics uye mhinduro kwayo yakagadzikana pamhepo tembiricha isina chero kusvibiswa kwescosity kunze kwekugona kweiyo enzymatic kusvibiswa kwe enzymatic.
3.
HydroxyPropyl methylcellulose Acd uye Alkali Kudzivisa Hydroxpropropylselpropropropylse inowanzogadzikana kuAcid naAlkali, uye haina kukanganiswa muhukuru hweh 2 ~ 12. Inogona kutsungirira huwandu hwechiedza chekidhi. Yakadai seyakarongeka acid, acidic acid, citric acid, succive acid, phccinic acid, phishicic acid, etc. Nekudaro, yakaisirwa acid ine mhedzisiro yekuderedza viscosity. ALKALI SEZVINOGONA SODAT SODA
4. Kusanganisa kwehydroxyprupyl methylcellose
Kusanganisa kwe hydroxyprusyl methyl cellroxpropypressl metdroxylpropyl methyl solulose mhinduro inogona kusanganiswa nePolymer's polymer yekuve yunifomu uye yakajeka mhinduro uye yakajeka mhinduro ine yakakwira viscosity. Iyi polymer compound inosanganisira polyethyl, polyvinyl acetate, polysiloxane, polysiloxane Naturalmer Polymer makomputa akadai segamu arabic, mhashu bean gum, karaya gamu, nezvimwewo uve nemabasa akanaka nemhinduro yayo. HydroxyPropyl methylcellose inogona zvakare kusanganiswa neMamnitol kana Sorbitol geners yeAcid kana Palmiti acid, uye inogona zvakare kusanganiswa ne glycerin, sorbitol uye mannitol. Aya makomputa anogona kushandiswa sehydroxyprupyl methylcellose. Cellulose-based plasticzezer.
5. Insolubility uye mvura solubility ye hydroxypropyl methylcellose
Iyo insolubilised yemvura-solulable cell-erdroxproproproproproplose inogona kunge iri pamusoro-Crosslinked neAldehydes, uye aya emahara emvura zvakavezwa mumhinduro uye azozvidzwa nemvura. Iyo Aldehydes inoita hydroxyprupyl methylcellose insolsellose inosanganisira Formaldehyde, Glyoxal, Succinalyeyde, etccinalyehded Naizvozvo, Glyoxal inowanzoshandiswa seyekuchinjika mumiririri mukugadzira maindasitiri. Iyo Dosage yerudzi urwu rwekuyambuka mumugodhi iri muCrime Iyo general kurapwa tembiricha ndeye 0 ~ 30 ℃, uye 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 yekugadzirisa iyo mhinduro yekugadzirisa kwe3 ~ 6, uyezve aldehs . Iyo Acids inoshandiswa inosanganisira hydrochloric acid, sulfuric acid, phosphichic acid, succinic acid, pakati peiyo acid kana acidic acid yakakodzera, uye yakagadzirwa acid ndiyo yakanyanya kunaka. Iyo acid uye aldehyde inogona zvakare kuwedzerwa panguva imwe chete kuti ibvumidze mhinduro yekuyambuka mune yaunoda pH range. Kuita uku kunowanzoshandiswa mukupedzisira kurapwa maitiro mukugadzirira maitiro e cellulose. Mushure mekunge cellulose ether is in in in in in in in in in in incoxident yekugeza nekuchenesa nemvura na20 ~ 25 ° C. Kana chigadzirwa chiri mukushandisa, chinhu cheAlkaline chinogona kuwedzerwa kune iyo mhinduro yechigadzirwa kugadzirisa iyo pH yemhinduro yekuve alkaline, uye chigadzirwa chichavhiringidza mumhinduro nekukurumidza. Iyi nzira inoshandawo kune iyo cellulose ether mhinduro yakagadzirwa mune firimu uye ipapo iyo firimu inogadziriswa kuti iite iyo insoluble firimu.
6. Hydroxypruppropyl methylcellose inodzivirira ku enzymes
Hydroxyprupropyl methylcellose inodzivirira ku enzymes. Mufundisi, mheremalose derverivives, senge boka rega rega renhau rekutsiva, iro risinganyorerwe riinhi kuiswa kweboka rimwe nerimwe, iro rinoreva kuti enzara isina kusarudzika Anhydroglucese mapoka ekugadzira mashuga. , iyo inobatwa seyakavimbika kune microorganisms. Naizvozvo, kana iyo ertifitation kutsiva kwemheremello inowedzera, kuramba ku enzymatic kuumbwa kwe cellulose ether inowedzerwa. Zvinonzi iyo yakasara viscosity ye hydroxyprosyl methylcellose (DS = 2.9) ndeye 13.2%, methylcellulose (DCHylcellose (DS = methylcellulose (2.66) ndeye 3.8%, uye hydroxytlyl cellulose is 1.7%. Inogona kuoneka kuti kugona-kwe enzyme kugona kwehydroxypruppropyl methylcellose yakasimba. Naizvozvo, akanakisa enzyme kuramba hydroxypropropropleselfeselculose, akasanganiswa nekupararira kwayo kukuru, anowanzoitwa mumvura, etc., uye kazhinji haingade kuwedzera kwekuwedzera. Nekudaro, zvekuchengetedza kwenguva refu kwemhinduro kana kusvibiswa kwenyika kunze kwenyika, chengetedza zvinogona kuwedzerwa sekungwarira, uye sarudzo inogona kutsanangurwa maererano nezvinodiwa zvekupedzisira zvemhinduro. Phenylmercuric Acetate uye Manganese Fluorosis Inoshanda Anochengetedza, asi ivo vane mutoro unobhadharwa, kutariswa kunofanirwa kubhadharwa pakuvhiya, uye doisa kazhinji 1 ~ 5mg ye phenylmercuric acetate per litre yemhinduro.
7. Zvivakwa zveHydroxyPropyl methylcellose firimu
Kuita kwehydroxyprenyl methylcellose firimu hydroxpropropylselpropylose Uye firimu rakaoma. Iyo ine yakanaka yekunyorova kupokana uye inoramba yakasimba pakupisa kwakanyanya. Semuenzaniso, kuwedzera hygrapic plasticikizer inogona kusimudzira macomputer yayo uye kuchinjika. Kuti uvandudze kuchinjika, mapurasitiki akadai se glycerin uye sorbitol ndiyo yakakodzera kwazvo. Iyo General Solution Kukurukurirana ndeye 2% ~ 3%, uye huwandu hwePlasticzezer ndeye 10% ~ 20% ye cellulose ether. Kana zviri mukati mepapurasitiki zvakanyanyisa, chinonyanya kuoma cheshuwa hwekushaiwa kwemvura yekodhi zvichaitika pasi penyama huru. Simba remafirimu refirimu rine plasticzer rakawedzerwa rakakura kupfuura iro pasina planticzezer, uye inowedzera nekuwedzera kwehuwandu hwakawedzerwa. Kana iri hygroscopicity yefirimu, inowedzerawo nekuwedzera kweiyo planticzer huwandu.
