Cellulose ether inobva kune kirasi yemakemikari yakagadziridzwa natural cellemers polymers. Nekuda kwekunaka kwavo kwemvura solubility, viscossity yekugadzirisa kwemamiriro ezvinhu kune ekunze mamiriro akadai sekupisa uye pH, ivo vanoshandiswa zvakanyanya muzvivakwa zvekuvaka, machira, mishonga, zvekudya uye zvidhori. Iyo viscosity control basa re cellulose ether ndiyo imwe yeiyo core maitiro ekushandisa kwayo mune yakawanda application mune yakawanda maindasitiri uye ezuva nezuva maapplication.
1. Chimiro uye kuiswa kwe cellulose ana
Cellulose ether inobva kune yakagadzirirwa kubva kune yakasikwa cellulose kuburikidza nekutsvaita maitiro. Cellulose ndeye polymer compound yakaumbwa ne glucose monomers yakabatana ne β-3,4-glycosic zvisungo. Maitiro ekugadzirira e cellulose anowanzo kusanganisira kuitwa nehydroxyl (-OOOH) chikamu chemutengesi weCellulose.
Zvichienderana neiyo scriptutuent, yakajairika cellulose etherivives inosanganisira methyl cellelose (HPMC), etc. Nhamba yacho uye chinzvimbo chevakatsauka hazviite chete iyo solubilse yemvura yemvura ye cellulose.
2. Viscossity yekufananidza mechanism
Iyo viscosity ichidzora mhedzisiro yemasero eva Cellulose ana ana kubva mukuparadzwa kwavo mumvura uye maitiro ekuwedzera emaketani anonyora. Kana cellulose ana vana akanyungudika mumvura, mapoka ehupombwe anogadzira mahyrogen nemamolekyudhi emvura, achizotenderedza maneleculose maneja, achiwedzera kupokana kwemvura, uye nekudaro achiwedzera zvisizvo mhinduro.
Hukuru hweViscosity hune hukama zvakanyanya neyekunyatso kuremerwa, substituent mhando, degree rekutsiva Kazhinji, yakakura kwazvo inorema yemheremello ye cellulose eter uye yakareba iyo molecular cheni, yakakwira iyo viscosity yemhinduro. Panguva imwecheteyo, vakasiyana vakasiyana vanokanganisa hydrophilicity yemasangano ether mamorekuru, uye nekudaro anokanganisa solubility newubility uye viscosity mumvura. Semuenzaniso, HPMC ine yakanaka mvura solubility uye viscosity kugadzikana nekuda kweiyo hydroxypruppropyl uye methyl siki. CMC, zvakadaro, ine yakakwira viscosity nekuti inounza zvisina kukodzera kubhadharisa mapoka emapoka emapoka, ayo anogona kutaurirana zvakanyanya nemamolekora emvura mumvura.
3. Mhedzisiro yezvinhu zvekunze pane viscosity
Iyo viscosity yemasero ether inobvidzana kwete chete pachimiro chayo chete, asi zvakare pane zvekunze kwezvakatipoteredza, kusanganisira tembiricha, ph kukosha, etcentration, nezvimwe.
3.1 tembiricha
Tembiricha chinhu chakakosha chinokanganisa viscosity yemasero ether mhinduro. Kazhinji, iyo viscosity ye cellulose ether mhinduro inoderedza nekuwedzera kupisa. Izvi zvinodaro nekuti kupisa kupisa kwemanyorero, kunokanganisa kudyidzana pakati pemamorekuru, uye kunokonzera mwero wekukwereta kwemvura mumvura kuti uwedzere mamorekuru, nekudaro achideredza viscosity. Nekudaro, mimwe cellulose etero (senge hpmc) kuratidza iyo thermal hunhu mukati meiyo tembiricha yekupisa, kureva kuti tembiricha yekuwedzera, iyo yekudzidzira visikoka inowedzera uye pakupedzisira inoumba gel.
3.2 PH Kukosha
Iyo PH Kukosha zvakare ine kukosha kwakanyanya pane viscosity ye cellulose ether. Kune cellulose ana ana eionic substituets (yakadai seCMC), iyo ph kukosha inokanganisa iyo yekubhadhara mamiriro emhinduro mumhinduro, nekudaro anokanganisa kuwirirana pakati pemamolecules uye viscosity yemhinduro. PaKukotesheni Phengo, boka reCarboxyl rinowedzera, rinokonzerwa nesimba rakasimba rekudzora remagetsi, vachiita kuti tambo yeMolecular iri nyore kuoneka uye inowedzera viscosity; Ndichiri kuderera phengo, iyo carboxyl boka harisi nyore ionised, iyo yemagetsi yekudzora yakaderedzwa, iyo ma molecular temple curls, uye visikoka vanoderera.
3.3 ion constentration
Mhedzisiro yeIion Constrenration pane viscosity ye cellulose ether inonyanya kuratidza pachena. Cellulose ether neIionic subsituets ichakanganiswa nemhedzisiro yekuchengetedza kweshoko rekunze mumhinduro. Sezvo iyo ION yekufunga kweiyo mhinduro inowedzera, iyo ekunze ichinetesa iyo Electrostatic kudzora pakati peCellulose Molecules, achigadzira iyo carular curl yakanyanya, nekudaro ichidzikisa mavheti eiyo mhinduro. Kunyanya munzvimbo ine munyu-munyu, iyo visikopa yeCMC ichaderera zvakanyanya, iyo ndeye yakakosha kukosha kwekugadzira mashandiro.
4. Viscosity kudzora muminda yekunyorera
Cellulose ether yakashandiswa zvakanyanya muminda yakawanda nekuda kweiyo yakanaka viscosity yekugadzirisa maitiro.
4.1 zvekuvaka
Muzvivakwa zvekuvaka, cellulose ether (senge hpmc) zvinowanzoshandiswa mune yakaoma-yakavhenganiswa, tily inonamatira uye inosimbisa iyo fluidity uye yekunyepedzera-sagging zvivakwa panguva yekuvaka. Panguva imwecheteyo, zvinogona kunonoka kupepuka kwemvura, kuvandudza kuchengetwa kwemvura kwemvura, uye nekudaro kunatsiridza simba uye kusimba kwechigadzirwa chekupedzisira.
4.2 majasi uye inks
Cellulose ana ana vana vanoita sehana uye stabilizers mumvura-yakavakirwa mvura uye inki. Nekugadzirisa iyo viscosity, ivo vanoona kuti kuyambuka uye kuderedza kwekuvhara panguva yekuvaka. Uyezve, zvinogona zvakare kuvandudza kurwisa-kupaza-kupaza kwekuvhara, kuderedza kupunzika, uye kuita kuti kuvakwa kwakawanda kwakawanda.
4.3 mushonga uye chikafu
Muminda yemushonga uye chikafu, cellulose etile (senge hpmc, cmm) inowanzoshandiswa sehana, emhungu kana stabilizer. Semuenzaniso, HPMC, sechinhu chinobatanidza mahwendefa, zvinogona kuwana mvumo yekusunungura yemishonga nekudzora chiyero chekunyungudika. Muchikafu, CMC inoshandiswa kuwedzera viscossity, kuvandudza kuravira, uye kuwedzera hupenyu hwesherufu hwekudya.
4.4 cosmetics
Iko kushandiswa kwe cellulose ana vana mune cosetics kunonyanya kutaurwa muzvigadzirwa senge emulsions, Gels uye kumeso masks. Nekugadzirisa iyo viscosity, cellulose etana inogona kupa chigadzirwa chakakodzera uye chimiro, uye gadzira iyo moisturizing firimu paganda kuti uwedzere nyaradzo panguva yekushandisa.
Cellulose ether inobva inokwanisa kudzora zvinobudirira kudzora zvikwangwani zvemhinduro kuburikidza neyavo yakasarudzika molecular chimiro uye kutevedzera kune ekunze nharaunda. Izvi zvakakonzera kushandisirwa kwavo muminda yakawanda senge kuvaka, mushonga, chikafu, uye zvizoro. Nekukura kwesainzi kwesainzi uye tekinoroji, mashandiro emaserolose aunganidzirwazve kuti ape zvakanyanya kuverengera zvimisikidzo zvekudzora mimwe nzvimbo.
