Zvinhu zvinokanganisa kugadzirwa kweViscosity ye hydroxyprusypressl methylcellose

Hydroxyprupyl methylcellose (HPMC)Iyo polymer inoshandiswa zvakanyanya mumasango akasiyana-siyana, kusanganisira mishonga yemishonga, chikafu, kuvaka, uye cosmetics. Yayo viscosity inotora basa rakakosha mune zvawo zvinoshandiswa. Kunzwisisa zvinhu zvinokanganisa HPMC viscosity kugadzirwa kwakakosha kuti ugadzirise mashandiro ayo mune akasiyana mamiriro. Nekunzwisisa kuongorora izvi zvinhu, vanochinjisa vanogona nani kushandisa hpmc zvivakwa kuti tisangane nezvakangoita application zvinodiwa.

Nhungamidzo:
HydroxyPropyl methylcellose (HPMC) inzira inoverengeka ine nzvimbo dzakapararira nekuda kwezvivakwa zvavo zvakasarudzika, kusanganisira kusarudzika kwemvura, uye kugona muviri. Imwe yeiyo yakaoma paramita inokanganisa kuita kwayo ndeye viscosity. Iyo viscosity yeHPMC Solutions inokanganisa maitiro ayo mune dzakasiyana-siyana zvikumbiro, zvakadai sekurema, gomba, firimu-coating, uye kusunungurwa mukuburitswa kwemishonga yemishonga. Kunzwisisa zvinhu zvinotonga HPMC viscosity kugadzirwa kuri paramount kweanogadzirisa mashandiro ayo muindasitiri akasiyana.

Zvinhu zvinokanganisa HPMC viscosity kugadzirwa:

Solley Huremu:
Uremu hwemulecular hweHpczvakakura zvinokanganisa zvavakaita zvavakaita. Yakakwira molecular uremu polymers kazhinji inoratidzira yepamusoro viscosity nekuda kwekuwedzera keteni. Nekudaro, zvakanyanyisa kukwirisa molecular uremu hunogona kukonzera matambudziko mukugadziriswa kwekugadzirisa uye kugadzirisa. Naizvozvo, kusarudza yakakodzera mamexer uremu huwandu hwakakosha kune zvinodiwa pakuenzanisa zvinodiwa nezviitiko zvinoshanda zvine chekuita.

Degree rekutsiva (DS):
Dhigirii rekutsiva rinoreva nhamba yepakati yeiyo hydroxyprupyl uye methy subsitue per Anhydroglucose unit muCellulose Chain. Yakakwira DS Changes inowanzoguma nekukwira viscosity nekuda kwekuwedzera hydrophilicity uye kutarisisa ketani. Nekudaro, kunyanyisa kutsiva kunogona kutungamira mukuderedza kwekunyora uye maitiro egungwa. Naizvozvo, optimizing iyo DS yakakosha pakuzadzisa iyo yaunoda viscosity uchiramba uchigadzirisa uye kugadzirisa.

Kusimbisa:
HPMC viscosity iri zvakananga zvakananga kusvika pakusangana kwayo mumhinduro. Sezvo polymer yekushamwaridzana inowedzera, nhamba yemapolymer maketins payuniti inowedzerawo, inotungamira kune yakawedzera kuchena keteni uye yakakwirira viscosity. Nekudaro, pakukwirira kwakanyanya, viscosity inogona kuputika kana kuderera nekuda kwePolymer-polymer yekudyidzana uye inoitika kugadzirwa kweGel. Naizvozvo, optimingozurity clontration inokosha yekuzadzisa iyo yaunoda viscosity pasina kukanganisa kugadzirisa kugadzikana.

Tembiricha.
Tembiricha ine kukosha kwakanyanya pane viscosity yeHPMC mhinduro. Kazhinji, viscosity inoderera nekuwedzera tembiricha nekuda kwekudzora polymer-polymer yekudyidzana uye yakawedzera kusungirirwa molecular. Nekudaro, mhedzisiro iyi inogona kusiyana zvichienderana nezvinhu zvakadai se polymer kusarudzika, zvinorema zvinorema, uye zvakanangana nemanomano kana ekuwedzera. Tembiricha yekudziya inofanirwa kutariswa kana ichigadzira zvigadzirwa zveHPMC-based kuti ive nechokwadi chekuita nekuita kwakasiyana tembiricha.

Ph:
Iyo pH yemhinduro inokonzeresa HPMC viscosity kuburikidza nemhedzisiro yacho pane polymer solubility uye kuenderana. HPMC inonyanya kuvezwa uye inoratidzira yakanyanya viscosity mune zvishoma acidic kune isina kwayakarerekera ph. Kutsauka kubva kune ino PH range kunogona kutungamira kuderedzwa kwekunyora uye viscosity nekuda kwekuchinja muPolymer Conform uye kuwirirana ne solvent mamorekuru. Naizvozvo, kuchengeta yakaringana ph mamiriro yakakosha pakukudza hpmc viscosity mune mhinduro.

Kuwedzera:
Zvakawanda zvinodhaka, zvakadai semunyu, surfacts, uye co-solventes, inogona kukanganisa hpmc viscosity nekuchinja kweSolution mhinduro uye polymer-solvent yekudyidzana. Semuenzaniso, munyu unomanikidza kuvandudza viscosity kuburikidza nekubatana-kunze kwemhedzisiro, nepo surfacts inogona kupesvedzera kushushikana uye polymer solubility. Co-sol moventes inogona kugadzirisa solvent polarity uye kusimudzira Polymer Solubility neViscosity. Nekudaro, kuwirirana uye kuwirirana pakati peHPMC uye vanowedzera vanofanirwa kuongororwa nokungwarira kuti vadzivise zvisingaverengeki zvakashata pamisangano uye kuita kwechigadzirwa.

inzvimbo yezvinhu zvakasiyana-siyana inoshandiswa zvakanyanya mumishonga yemishonga, chikafu, kuvaka, uye maindasitiri ezvidhinha. Iyo viscosity yeHPMC mhinduro dzinoita kuti basa rakakomba mukusarudza mashandiro ayo mune dzakasiyana siyana application. Kunzwisisa zvinhu zvinokanganisa hpmc viscosity kugadzirwa, kusanganisira molecular uremu, degree rekutsiva, kusvinura, tembiricha, kupembera, kunokosha, kunokosha kuti ugadzirise mashandiro ayo uye kuita kwayo. Nekunyatsotarisana nezvinhu izvi, vanobata vanogona kugadzirisa hpmc zvivakwa kuti tisangane chaizvo application zvinodiwa zvinobudirira. Kuwedzera kutsvagisa muzvikamu pakati pezvinhu izvi zvicharamba zvichikwira nzwisiso yedu uye kushandiswa kweHPMC mune dzakasiyana maindasitiri maindasitiri zvikamu.
