1. Nzira yekudzvinyirira yeTetHyl Cellulose
Ethyl Cellulose (EC) ndeyemakemikari yakagadzirwa neTETYLATINATION YEMAHARA CellELOSE, iyo ine yakanaka biocomputilation, isiri-yehupfu uye deghdity. Nekuti chimiro chayo chine huwandu hukuru hwe hydroxyl uye mapoka emapoka, ane zvimwe zvinetso mukunyungudika. Kuti vaite zvinobudirira kudzvinyirira ethyl cellulose, nzira dzakanyungudika uye solvent dzinowanzodiwa.
Solvent Sarudzo
Iyo solubility yeTETHYL Cellulose zvinoenderana neyakaomarara uremu, degree rejisholi uye solvent yakasarudzwa. Nekuda kwehunhu hwekuumbwa kweTEthyl Cellelose, zvinowanzoitika mumvura, asi zvinogona kunyungudutswa mune dzakasiyana siyana organic sol. Inowanzo shandiswa sol soles inosanganisira:
Doro Sol Solventes: Dzakadai se ethanol, isopropanol, n-prencanol, etc., ethyl cellulose inoratidza yakanaka solubility.
Ether solventes: senge dimethyl sulfoxide (dmso), chloroform, etc., inogona kunyungudutsa ethyl cell.
Ketone solventts: senge acetone, etc., yakakodzera kupaza kwepakati svutugadzike yeEtiyl cellulose.
Clorines Sol Solvents: Yakadai seChloroform, carbon tetrachloride, etc., inogona zvakare kushandiswa semheni, asi kuchengetedzwa kunofanirwa kutariswa kana uchiverengera.
Matanho ekupaza
Matanho ekunyungudutswa eEthyl Cellulose anowanzoita seinotevera:
Pre-Dishlution: Nyatsowedzera Wedzera EtHyl Cellulose Solvent Solvent yakakwana kufukidza iyo Ethyl Cellulose, uye zvinyoronyoro pamhepo tembiricha kuti ibatsire kupararira zvakanyanyisa.
Kupisa kushungurudzika: Kana zvakaoma kunyungudutswa pamhepo tembiricha, tembiricha inogona kuwedzerwa nenzira kwayo (kazhinji isiri inopfuura makumi manomwe ° C) uye kupisa pasi pekumutsa kuita kuti iyo ethyl cellulose ive nyore kunyungudika.
Deckassing: Mushure mekunge kupaza kupedzwa, kana paine mabhuruku mune solvent, mabhuruku anogona kubvumidzwa kutiza nekudzora kudzvinyirira kana kumira kwenguva yekugadzikana uye kufanana kwemhinduro yekupedzisira.
Kuchenjerera panguva yekupararira
Kudzora kusungwa: Zvakanyanya kunaka Etyl Cellulose Connelose inogona kukonzera kuomarara mukupararira. Inokurudzirwa kugadzirisa iyo solubility sezvazvinodiwa.
Solvent Sarudzo: Yakasiyana yeTthyl Cellulose Models (yakadai seyakasiyana mameculars, madhigirii akasiyana-siyana) ane zvimiro zvakasiyana zvemagetsi. Kusarudza solijeti yakakodzera inobatsira kuvandudza kusanzwisisika kwekunyanyisa.
2. Kushandiswa kukuru kweTETHYL Cellulose
EtHyl Cellulose anoshandiswa zvakanyanya muminda yakawanda nekuda kwemhando yayo yakanaka uye yemakemikari (senge solubility, firimu-kugadzira, etc.). Heano mamwe emashandisirwo ekushandiswa kukuru:
Anodhaka Anodzorwa Kuburitsa Mutakuri
Ethyl Cellulose ane yakanaka biocomputilation uye biodergradability, uye inowanzoshandiswa seinodhaka yakasungirirwa mumiriri kana kudzorwa mumiririri. Inogona kuvandudza kushanda kwezvinodhaka uye kuderedza mhedzisiro nekudzora kumhanya uye nguva yekuburitswa kwezvinodhaka. Zviitiko zvizhinji zvinosanganisira mishonga yemuromo, transdermal drug tatches, nezvimwe.
Coatings uye membrane zvinhu
EtHyl Cellulose ane yakanakisa firimu-inoumba midziyo uye masimba masimba, saka inoshandiswa zvakanyanya mune zvekudya uye zvinodhaka. Inogona kuumba yakaonda uye yunifomu firimu layer yekuchengetedza zvinhu zvemukati kubva kune ekunze nharaunda uye kuwedzera kugadzikana uye mareru echigadzirwa chechigadzirwa. Zvakajairika kuunganidza zvikumbiro zvinosanganisira shuga yekukanda, zvinodhaka coting, etc.
Indasitiri yechikafu
Muindasitiri yechikafu, ethyl cellulose inoshandiswa zvakanyanya seyakawedzera chikafu. Inogona kushandiswa seanoti, stabilizer, emulsifieri, nezvimwe. Semuenzaniso, ethyl cellulose inogona kushandiswa seyinotsiva kune yakaderera-calorie chikafu kubatsira kudzora zvirimo mafuta uye shuga.
Cosmetics indasitiri
Mune cosmetics, ethyl cellulose inowanzoshandiswa seyekupedzisira, emulsififier uye yefirimu yaimbova, iyo inogona kuvandudza kuwirirana, kugadzikana uye kubata kwe emulsion kana ichishandiswa. Semuenzaniso, ethyl cellulose inogona kuwanikwa mune zvigadzirwa zvakadai sekutarisana nemazvo, madhiri, uye miromo.
Pepa uye machira ekugadzirisa
Sekusha kwechiitiko chechisikigo cellulose, ethyl cellulose inoita basa rakakosha mukugadziriswa kwepepa uye zvinyorwa. Inogona kuwedzera simba repepa, kuvandudza chimiro chepamusoro, uye nekuvandudza kudzikisira kwepaiti uye kuparadzaniswa kwemavara.
Coatings uye pendi
Sefirimu raimbova yejasi, ethyl cellulose inowanzoshandiswa mukugadzirwa kwemapendi uye majasi. Zvinogona kuvandudza kusimba, kugadzikana uye kuderedza kwematombo, uku uchivandudza gloss yekubatanidza.
Zvemamiriro ekunze zvinoshamisa
Nekuda kwekunyora kwayo uye kuderera kwethudhudhudhudhi, ethyl cellulose yakave zvakare yakadzidzwa mukuvandudzwa kwemamiriro ekunze ane hushamwari. Semuenzaniso, muminda yekubatwa kwemvura uye kuvandudzwa kwevhu, hunhu hwezvakatipoteredza hweTetHyl Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Inoita Kuti Icho Chinyorwa Chinyorwa Chakakura Nekugona Kukosha.
Sechinhu chakakosha chemakemikari, ethyl cellulose inoita basa rakakosha muindasiti dzakawanda. Nzira yayo yekunyungudika inonyanya kuenderana nesarudzo yemashirimo emhando, uye mashanga akajairika anosanganisira Alohols, mhandara, uye ketetoni. Maererano nekushandiswa kwakasiyana, maEthalose anogona kushandiswa zvakanyanya mukushandiswa kwezvinodhaka Nekuwedzera kwekuwedzera kwegirini uye zvakatipoteredza zvinoshamwaridzana zvinhu, tarisiro yekushandisa yeTetHyl Cellulose yakakura kwazvo.
