Yakadzika-yakatsiva hydroxyprusterl Cellulosel Cellulose L-HPC yakagadziridzwa kusimudzira iyo solubility uye zvimwe zvinhu zvivakwa, zvichiita kuti zvinhu zvive zviviri nezvakareruka zvine manyorerwo akawanda mune mishonga, chikafu, uye maindasitiri ezvekudya.
Yakadzika-yakatsiva hydroxypropropylcellose (L-HPC) yakaderera-yekutsiva cellulose yakagadziriswa iyo yakagadziridzwa kunyanya yekugadzirisa iyo solubility mumvura uye mamwe mashirimo. Cellulose ndeye mutsara wezinesi polysaccharide yakaumbwa neyezvitunha zvacho zvakawanda mune zvakasikwa uye chinhu chomukati chechimiro chemadziro emasero. L-HPC inogadziriswa nemakemikari kugadzirisa cellulose, kuunza hydroxyprosyl mapoka ekusimudzira iyo solubility yayo ichiramba imwe yezvinhu zvinodikanwa zve cellulose.
Chemical chimiro che low-substited hydroxypruppropyl cellulose
Chemical chimiro cheLPC chine cellulose backbone uye hydroxypruspropyl boka rakabatanidzwa kune hydroxyl (oh) boka reGlucose unit. Dhigirii rekutsiva MuLPC, iyo DS ine chinangwa yakachengetwa yakaderera kuti ibatanidzwe kugadzirisa solubility nekuchengetedza zvinhu zvemukati zve cellulose.
Synthesis of yakaderera-yakatsiva hydroxypropyl cellulose
Iyo Synthesis yeLPC inosanganisira kuitwa kweCellulose neProulyery Oxide muHupo hweAlkaline Catalyst. Kuita uku kunoguma nekutanga kwehydroxyprupropyl mapoka mune cellulose maketani. Kunyatso kutonga kwemamiriro ekuita, kusanganisira tembiricha, maitiro ekushisa, uye kusimbisa kwezano, kwakakosha kuti uwane huwandu hunodiwa hwekutsiva.
Zvinhu zvinokanganisa Solubility
1. Degree rekutsiva (DS):
Iyo solubility yeLPC inokanganiswa neiyo DS yayo. Sezvo DS inowedzera, iyo hydrophilipity yeiyo hydroxpropropyl boka rinowedzera kutaurwa, nekukasira kugadzirisa solubility mumvura uye polar sol.
2. Sollelar uremu:
Iyo smecular uremu hweLPC ndechimwe chinhu chakakomba. Yakakwira Molecular uremu L-HPC inogona kuratidza yakaderedzwa solubility nekuda kwekuwedzera intermolecular yekudyidzana uye machera emachinda.
3. Tembiricha:
Solubility kazhinji inowedzera ne tembiricha nekuti tembiricha yakakwirira inopa simba rakawanda kupwanya mauto e-polymer-solmer.
4. PH Kukosha kweSolution:
Iyo pH yemhinduro inobata ionization yeiyo hydroxyprupropyl mapoka. Mune zvimwe zviitiko, kugadzirisa iyo pH inogona kuwedzera iyo solubility yeLPC.
5. Solvent mhando:
L-HPC inoratidza yakanaka solubility mumvura uye akasiyana polar sol. Iko kusarudzwa kwe solvent kunoenderana nechero chaicho application uye iyo yaunoda zvinhu zvechigadzirwa chekupedzisira.
Kushandiswa kweyakaderera kutsiva hydroxypropyl cellulose
1. Zvinodhaka:
L-HPC inoshandiswa zvakanyanya muindasitiri yemishonga seyakagadzirwa, kuparadzaniswa uye kudzorwa kwekusunungurwa mumiririri mukugadzira piritsi. Yayo solubility mune gastrointestinal fluid inoita kuti iite yakakodzera kune zvinodhaka zvekutumira zvinodhaka.
2. Indasitiri yechikafu:
Muindasitiri yechikafu, LPC inoshandiswa seanoshandiswa uye stabilizer mune zvakashata zvigadzirwa. Kugona kwayo kuumba gel yakajeka isina kukanganisa kuravira kana ruvara rwezvigadzirwa zvekudya zvinoita kuti ive yakakosha mukuumbwa kwekudya.
3. Cosmetics:
L-HPC inoshandiswa mune cosmetic formautication yeiyo firimu-inoumba uye yakakora nzvimbo. Iyo inobatsira kuvandudza kugadzikana uye kuumbwa kwemazino akadai sekiriniki, lotions uye geels.
4. Kubatanidza application:
L-HPC inogona kushandiswa seye firimu inovhara zvinyorwa mumisheni uye maindasitiri ezvekudya kuti ape denderedzwa remahwendefa kana zvigadzirwa zvezvinorema.
Yakadzika-yakatsiva hydroxypruppropyl Cellulose inzvimbo yeClementional polymer ine yakasimbiswa Solubility inowanikwa kubva kune yakasikwa cellulose inowanikwa muzvirimwa. Zvivakwa zvaro zvakasarudzika zvinoita kuti zvive zvakakosha mumasango akasiyana siyana kusanganisira mishonga yemishonga, chikafu uye cosmetics. Kunzwisisa izvo zvinhu zvinopesvedzera iyo solubility yakanyanya kutsoropodza kushandisa kwayo kushandiswa kwakasiyana. SaPolymer Science Kutsvaga uye Budiriro inoenderera, LPC uye yakafanana cellulose DEFUTVES inogona kuwana manyoro matsva uye anokurudzira ekushandisa muminda yakawanda.
