Hydroxypropyl methylcellulose (HPMC) is a non-ionic water-soluble cellulose ether inoshandiswa zvakanyanya mukuvaka, mushonga, chikafu, cosmetics uye makemikari maindasitiri. Iyo viscosity maitiro eiyo aqueous mhinduro ndizvo zvakakosha zvinokanganisa kushanda kwayo kwekushandisa.
1. Basic maitiro eHPMC
AnxinCel®HPMC inhengo ye cellulose inogadzirwa nekuunza hydroxypropyl uye methyl mapoka muketani yemamorekuru e cellulose. Iyo ine yakanaka solubility yemvura uye yakanyanya viscosity, uye inowanzoshandiswa kugadzirira aqueous mhinduro ine chaiyo rheological properties. Aya maitiro anoita kuti HPMC ishandiswe zvakanyanya mumajasi, zvinonamira, zvinodhaka zvinoburitswa kuburitswa, zvekuwedzera zvekudya uye mamwe maindasitiri.
2. Viscosity maitiro eHPMC aqueous solution
Iyo viscosity maitiro eHPMC aqueous solution inokanganiswa nezvakawanda zvinhu, kunyanya zvinosanganisira kusungwa, tembiricha, shear rate, pH kukosha uye mamorekuru chimiro.
Mhedzisiro yekuisa pfungwa pane viscosity
Iyo viscosity yeHPMC aqueous solution inowedzera nekuwedzera kusungwa. Kana huwandu hweHPMC hwakaderera, mhinduro ine aqueous yakatetepa uye ine yakaderera viscosity; sezvo kuwedzera kunowedzera, kuwirirana pakati pemamorekuru kunowedzera, uye viscosity yemushonga wemvura unowedzera zvakanyanya. Kazhinji, viscosity yeHPMC mhinduro ine hukama nehukama hwayo, asi inowanzove yakagadzikana pane imwe pfungwa, inoratidza viscosity maitiro emhinduro.
Mhedzisiro yekushisa pane viscosity
Tembiricha chinhu chakakosha chinokanganisa viscosity yeAnxinCel®HPMC aqueous solution. Sezvo tembiricha ichikwira, iyo hydrogen zvisungo uye hydrophobic kupindirana muHPMC mamorekuru anopera simba, zvichikonzera kuderera kwesimba rinosunga pakati pemamorekuru, nekudaro kuderedza viscosity yemushonga wemvura. Kazhinji kutaura, iyo viscosity yeHPMC aqueous solution inoratidza yakakosha kudzika maitiro nekuwedzera tembiricha, kunyanya muyepamusoro tembiricha renji. Hunhu uhu hunoita kuti HPMC ive nani kudzora kugona mune mamwe tembiricha ekudzora maapplication.
Mhedzisiro yeshear rate pane viscosity
HPMC aqueous solution inoratidza hunhu hweNewtonian fluid pamitengo yakaderera yekugera, kureva kuti, viscosity haina kugadzikana; zvisinei, pakukwirira kweshear rates, viscosity yeHPMC mhinduro ichaderera zvakanyanya, zvichiratidza kuti ine shear thinning properties. HPMC mamorekuru ane zvimwe rheological properties. Pazviyero zvakaderera zveshear, maketani e-molecular anowedzera kumonyoroka, achigadzira kukwirira kwemaitiro ekupikisa, iyo inoratidzwa seyakanyanya viscosity; pakukwirira kweshear mazinga, maketani emakemikari anowanzo kutambanudza, kunyunguduka kunowedzerwa, uye viscosity inoderera.
Mhedzisiro yepH kukosha pane viscosity
HPMC aqueous solution inowanzo chengetedza viscosity yakagadzikana pasi pekusarerekera kune isina simba alkaline mamiriro. Mune yakasimba asidhi kana yakasimba base nharaunda, HPMC mamorekuru anogona kuita protonation kana deprotonation reactions, zvichikonzera shanduko muhydrophilicity, hydrophobicity uye intermolecular kupindirana pakati pemamorekuru, nekudaro kukanganisa viscosity yemushonga wemvura. Mumamiriro ezvinhu akajairwa, shanduko mupH haina mhedzisiro pane viscosity yeHPMC mhinduro, asi pasi peyakanyanya pH mamiriro, iyo viscosity shanduko inogona kuve pachena.
Mhedzisiro yechimiro chemolecular pane viscosity
Iyo viscosity maitiro eHPMC ane hukama zvakanyanya kune ayo mamorekuru chimiro. Iyo dhigirii yekutsiviwa kwehydroxypropyl uye methyl mapoka mumorekuru ane mhedzisiro yakakosha pane viscosity yeaqueous solution. Iyo yakakwirira dhigirii yekutsiviwa kweboka, iyo yakasimba iyo hydrophilicity yeHPMC uye yakakwirira viscosity yemhinduro. Uye zvakare, iyo molecular huremu hweHPMC zvakare chinhu chakakosha chinokanganisa viscosity yayo. Kukura kwehuremu hwema molecular, kureba kwecheni ye molecular, uye kusimba kwekudyidzana pakati pemamorekuru, zvichikonzera kukwirisa viscosity yemushonga wemvura.
3. Kukosha kweiyo viscosity maitiro eHPMC aqueous solution mukushandisa
Iyo viscosity maitiro eHPMC aqueous mhinduro yakakosha pakushandiswa kwayo munzvimbo dzakasiyana siyana.
Munda wekuvaka: HPMC inowanzo shandiswa mudhaka resimende uye zvinonamira, uye ine mabasa ekukora, kuchengetedza hunyoro, nekuvandudza mashandiro ekuvaka. Hunhu hwayo hwe viscosity hunokanganisa zvakananga kushanda uye kunamatira kwedhaka. Nekugadzirisa iyo yekumisikidza uye mamorekuru chimiro cheHPMC, iyo rheological zvimiro zvedhaka zvinogona kudzorwa, nekudaro zvichivandudza kureruka kwekuvaka.
Indasitiri yemishonga: AnxinCel®HPMC aqueous solution inowanzo shandiswa mukugadzirira senge zvinodhaka zvinoramba zvichiburitswa, macapsule shells, uye madonhwe emaziso. Hunhu hwayo hwe viscosity hunogona kukanganisa kuburitswa kwezvinodhaka uye kutonga kuburitswa kwemishonga mumuviri. Nekusarudza HPMC ine huremu hwakakodzera hwemamorekuru uye dhigirii rekutsiva, maitiro ekuburitsa emishonga anogona kugadziriswa kuti awane chaiwo maitiro ekurapa.
Indasitiri yechikafu: HPMC inoshandiswa seyakakora, stabilizer, uye emulsifier mukugadzira chikafu. Iyo viscosity maitiro eiyo aqueous solution inokanganisa kuravira uye kugadzikana kwechikafu. Nekugadzirisa rudzi uye huwandu hweHPMC hunoshandiswa, magadzirirwo echikafu anogona kunyatsodzorwa.
Indasitiri yezvekuzora: HPMC, seyakakora uye inodzikamisa muzvizoro, inogona kuvandudza magadzirirwo echigadzirwa, ichichipa kuyerera kwakakodzera uye kunzwa kwakanaka. Hunhu hwayo hwe viscosity hune simba rakakosha paruzivo rwemushandisi wezvigadzirwa zvakaita semakirimu, gels, uye shampoos.
Iyo viscosity maitiro eHPMC mhinduro dzemvura dzinokanganiswa nezvinhu zvakawanda senge kutarisisa, tembiricha, shear rate, pH kukosha, uye mamorekuru chimiro. Nekugadzirisa zvinhu izvi, mashandiro ekushandisa kweHPMC anogona kuvandudzwa kuti asangane nezvinodiwa zvemaindasitiri akasiyana kune ayo rheological properties. Tsvagiridzo yakadzama pamusoro peiyo viscosity maitiro eHPMC aqueous mhinduro haingobatsire kunzwisisa kwayo ekutanga zvivakwa, asi zvakare inopa dzidziso yedzidziso yekushandisa kwayo mukugadzirwa chaiko.
