Hydroxye ethyl cellulose (Hec) ipolifaunti uye yakashandiswa zvakanyanya polymer, inopa basa rakakosha mune dzakasiyana siyana mumunda wemakemikari. Iyo mvura -soluble polymer iri muCellulose, uye cellulose ndeye polymer yakasikwa inowanikwa mumadziro ezvimedu cell. Sumo yeiyo hydroxyl boka rinogona kusimudzira iyo solubility yemvura uye shandura iyo yemuviri uye yemakemikari zvivakwa zve cellulose.
1. Nhanganyaya kuHydroxye Ethyl (Hec)
Hydroxye ether ndeyekutora Cellenulose, uye cellulose ndeye mutsara wepolymer yakaumbwa neyunivhesiti yeGlucose yakabatana neiyo β -,4,4-glycolide chisungo. Iyo hydroxyl boka muhec yakaunzwa nekuita nemhou. Uku kugadziridzwa kunowedzera solubility ye polymer mumvura, uye inoipa nehunhu hwakasiyana hwekutsvaga maficha mumakemikari akasiyana emakemikari.
2. Chimiro uye hunhu hwehwanda
Chimiro: Iyo hydroxyl boka rakabatanidzwa neiyo hydroxyl boka reketani yeiyo cellulose, iyo inopa hecom yakasarudzika uye isiri-founding zvivakwa. Dhigirii rekutsiva
Solubility: Hec inogona kunyungudika nyore nyore mumvura inotonhora, kugadzira mhinduro yakajeka uye viscous. Mhedzisiro yesalubility inokanganiswa nezvinhu zvakadai sekupisa, Ph uye Ion Simba.
Viscosity: imwe yezvinhu zvakakosha zvehec ndiko kugona kwayo kushandura visikopa yemhinduro. Izvi zvinoita kuti zvive zvakakosha mumaindasitiri anodzora fluid fluid.
3. Synthesis ye hydroxyl ethyl cellulose
Yakagadziriswa maitiro: Iyo synthesis yehyou inosanganisira maitiro pakati pemusangano uye oxide mukushaikwa kweAlkaline Catalysts. Iwe unogona kudzora iyo degree rekutsiva nekugadzirisa mamiriro ekuita (sekupisa, nguva, uye maitiro ekutsanangurwa).
Kuchenesa: Zvigadzirwa zvekupedzisira zvinowanzo kunatswa kubvisa kusvibiswa uye zvisingaonekwi reagents kuti uve nechokwadi chekuti hunhu hunodiwa hwe hec.
4. Chemical application
Pendi uye kuungana: HEC inoshandiswa zvakanyanya sekuremerwa uye stabilizers mumvura-pendi yekupenda uye marara. Iyo inovandudza maitiro ekushandisa uye inosimudzira kuyerera kwependi.
Cosmetics uye pachako Zvigadzirwa Zvigadzirwa: Nekuda kwemamiriro azvo emvura uye maitiro akakora, hec inogona kuwanikwa mune dzakawanda cosmetics uye yekuchengetedza mari, kusanganisira lotion, shampoo uye kirimu.
Pharmaceucal: Muchisheni Fomula, HEC inoshandiswa semapiritsi, firimu uye viscosity modifiers, mahwendefa ematafura, magirazi emunharaunda uye anodzorwa anodzora zvinodhaka kutumira kwezvinodhaka.
Indasitiri yekuvaka: Hec inoshandiswa kune zvekuvakisa zvekuvakisa, senge simende-permer uye zvinonamatira kuti vavandudze kuridzwa uye kudedera.
5. Basa remvura-rakatsaurwa
Pubin Fomula: Inosanganisa hec mumvura -kubva kumanamatira kuti ape hunhu hwekunamatira hwe viscosity kudzora, kugadzikana uye kuvandudzwa. Izvo zvinonyanya kubatsira mukushandisa zvisina kukodzera kwekushandiswa kweSolvent -Berased.
6. Simbisa Kugadzirisa Mafuta
Viscosity Modifier: mumafuta uye naturaini gasi maindasitiri, hec inoshandiswa seViscossity modifier yekuvandudza iyo yekugadzirisa mafuta (EORI) maitiro. Iyo inovandudza iyo visikoka yemvura inoshandiswa jekiseni, nekudaro ichisimudzira kudzingwa kwemafuta mune reservoir.
7. Kubata kwezvemamiriro ekunze uye kusimba
BIO DEGRADI: HEC inowanzoonekwa seyakavapo uye inobatsira kugamuchirwa kwaro. Nekudaro, kusimba kwakazara kwekugadzirwa kwayo kunoenderana nezvinhu zvakaita semafaro uye kugadzira maitiro.
8. DAMBUDZIKO uye REMUFUNDO Views
Biocompriction: Kunyangwe hec inowanzoonekwa yakachengeteka, yayo yekukanganiswa uye inogona kuitika hutano mune zvimwe zvekushandisa, kunyanya mumunda wezvekurapa uye zvinodhaka, zvichiri minda yekutsvaga.
Green yakazara: Kuenderera mberi kwekuedza kutarisa nezvekusimudzira kwemamiriro ekunze akashamwaridzana synthesis nzira dzekudzikisa maitiro ekutsigira kwekugadzirwa kwaro.
Hydroxyeyl Cellalose inotora basa rakakosha mumidziyo yemakemikari akasiyana, ichipa musanganiswa wakasarudzika wemvura -soluble, kushandurwa kwemasvomhu uye biodergradation. Pesvedzero yayo inoshambadzira maindasitiri akadai pende, zvizaradzi, mishonga, zvinonamatira uye kupora mafuta. Nekuenderera mberi kwekutsvagisa, chimiro chehec uye chaicho chingangoita muminda inobuda muminda inogona kuwedzera, nekudaro ichiramba ichikosheswa kumunda wechemistry.
