HydroxytHyl cellulose: kuongorora
HydroxytHyl Cellulose (Hek) is is is is is-ionic, yakadzika-mvura polymer yakawanikwa kubva ku cellulose, iyo yakanyanya kuwanda kwazvo polymer pasi pano. Nekuda kwezvivakwa zvaro zvinoitika
Synthesis ye hydroxytetl cellulose
Kugadzirwa kwehyoko kunosanganisira kuwedzerwa kwemheremello. Maitiro aya anotanga ne cellulose achibatwa ne sodium hydroxide kugadzira Alkali cellulose. Etleyle oxide inozowedzerwa kumusanganiswa uyu, zvichikonzera kuumbwa kwehydroxytl cellulose. Maitiro acho anogona kumiririrwa seinotevera:
Cellulose-ana + nch2ch2o → cellulose-och2ch2oh
Dhigirii rekutsiva DS inoreva huwandu hwemahara emapoka ehydroxyl pane cellulose Molecule akaiswa, nepo ms anoratidza huwandu hwehuwandu hwemagetsi eteralen exical. Iyi parameter inokanganisa iyo solubility, viscosity, uye zvimwe zvinoshanda zveshuwa zvehec.
Hec ine huwandu hwakati wandei hwakasarudzika:
Solubility: Hec inonyura mumvura inopisa uye inotonhora, iyo inoita kuti ive inoverengera zvakanyanya kune dzakasiyana siyana application. Inogona kuenzanisa yakajeka, iyo gobvu mhinduro dzakagadzikana pamusoro pakawanda ph range.
Viscosity: Iyo viscosity yemhinduro dzehishenje dzinoenderana neyakaomarara uremu uye uremu. Hec inogona kuburitsa akasiyana siyana vema viscokities, ichiita kuti ibatsire mune zvikumbiro izvo zvinoda chaiwo kuyerera maitiro.
Firimu-inogadzira kugona: Hec inogona kuumba inoshanduka-inochinjika, mafirimu akajeka. Ichi chivakwa chinonyanya kubatsira mumatombo uye cosmetics.
Akakora Agent: Hec ndiyo inoshanda yakakora mumiririri, inopa kusanzwisisika kwaunoda uye kugadzikana mukuumbwa.
Kugadzikana: Hec inogadzikana nemakemikari uye inodzivirira kusvibiswa nechiedza, kupisa, uye microorganisms, iyo inowedzera hupenyu hwayo hwakaringana mune dzakasiyana siyana.
Zvikumbiro zveHydroxyTHLYL Cellulose
Nekuda kwezvivakwa zvaro zvakasarudzika, hec inowana maficha muminda yakawanda:
Misheni: Muindasitiri yemishonga, hec inoshandiswa sechinhu chinokweva, firimu-raimbova, uye mumirapheni emapiritsi nemarara. Iyo inobatsira mukudzora zvinodhaka zvinodhaka uye zvinovandudza chimiro uye kugadzikana kwekufungidzira.
Cosmetics: Hec inowanzo shandiswa mune zvigadzirwa zvega zvega seShampoos, lotions, uye maFirti. Iyo inopa yavanopa viscossity, inovandudza kunzwa kwechigadzirwa, uye nekutsausa emulsions.
Pendi uye Mbira: Mune indasitiri yePendi, hec inoita seanoshanda sedhiketi, stabilizer, uye nekuchengetwa kwemvura. Iyo inovandudza mashandiro ezvekushandisa kwemapendi, anodzivirira kusekerera, uye anovimbisa kunyange kuumbwa kwemafirimu.
Kuvaka: Hec inoshandiswa mune zvekuvaka zvekuvaka senge simende uye plaster. Iyo inosimudzira kushandira, kuchengetwa kwemvura, uye kuderedza, kuvandudza mashandiro uye kusimba kwezvinhu izvi.
Indasitiri yechikafu: Kunyangwe zvisingasviki, hec zvinogona kushandiswa seanotenderera uye stabilizer mune zvimwe zvigadzirwa zvekudya, ichine chimiro chakatsiga uye kusawirirana.
Indasitiri yemidhinari: Hec inoshandiswa seyakagadzirirwa mumiririri muindasitiri yemidhinari, ichipa simba uye kugadzikana kune yarns panguva yekuchema.
Kuchengetedzwa uye zvakaringana kukanganisa
HEC inowanzofungidzirwa kuti yakachengeteka kushandiswa mune dzakasiyana-siyana maapplication, kunyanya mumishonga uye cosmetics, uko kwakaedzwa zvakanyanya nekuda kwekutadza uye kutsamwiswa. Izvo zvisiri-zvine muchetura, uye kusatsamwisa, uye hypoallergenic, zvichiita kuti zviite kuti zvishandiswe mune zvigadzirwa zvinoshandiswa kune ganda kana kumedzwa.
Kubva pamaonero emunharaunda, hec iri biodegradable uye inotorwa kubva mukuvandudza zviwanikwa (cellulose). Kugadzirwa kwayo uye kushandiswa kwakabatana nekudzikiswa kwenzvimbo dzemamiriro ekunze. Nekudaro, sezvakaita nemakemikari ese, kubata kwakakodzera uye kuraswa zvinodikanwa kuti uderedze chero njodzi dzezvakatipoteredza.
HydroxytHyl Cellulose inzvimbo inoverengeka uye yakakosha polymer ine huwandu hwakawanda hwekushandisa maindasitiri akasiyana. Zvivakwa zvaro zvakasarudzika, zvakadai sekusarudzika kwemvura, kushamisika kwemvura, kusimbisa kwefirimu kugadzira, uye kugadzikana, ita kuti ive yakakosha mune zvigadzirwa kubva kune mishonga yekuvaka kune zvekuvaka. Iyo synthesis yehec kubva ku cellulose inomiririra kushandiswa kwakanaka kwezvinhu zvakasikwa, zvichikonzera kusimba kwayo. Nechiratidzo chakasimba chekuchengetedza uye mashoma zvemamiriro ekunze, Hec inoenderera ichive yakakosha mune dzakasiyana siyana dzekutengesa uye maindasitiri.
