Nibihe bintu bya hydroxyyerthyl selile?

HydroxyAythyl Cellulose (HEC) ni polyment y'amazi y'ingenzi y'amazi ya selile ya ether ether. Iboneka muburyo bwa hahindutse selile karemano hamwe na etylene oxide (rotyne oxide) mubihe bya alkaline. HydroxyAythyl selile ni umurongo uhuza umurongo ugizwe n'ibice bya gikeri mu miterere ya glucose, kandi bimwe mu matsinda ya hydroxyl yasimbuwe n'amatsinda ya HYDROSETERYL kugira ngo asimburwe n'amatsinda ya hydroxyyerthyl.

Ibikoresho n'imiterere yimiti
Imiterere ya molekeritythyl selile ikubiyemo ahari ibice bikurikira:

Cellulose Inyuma: Cellulose ni PolySacharide PolySacharide, igice kinini cyacyo kirimo umurongo wumurongo wibice bya glucose bihujwe na β-1,4-glycosic bonds. Iyi miterere ya selile irayiha kristu yo hejuru nimbaraga zumubiri.

Hydroxyyeryl Sipossitent: Mu gice cya Glucose cya selile ya selile, hari amatsinda atatu ya hydroxyle (-Oh), iherereye kuri C2, V3 na C6 imyanya. Hydroxyyeryl selile ikorwa no kumenyekanisha hydroxyithyyl (-Ch2ch2oh) ku matsinda ya hydroxyl binyuze mu matsinda yatunganijwe hagati y'itsinda rya hydroxyl na Ethyne oxide. Iriburiro ryabatsinsino rigabanya inyamanswa rya selile, ritezimbere amazi yacyo, kandi rituma agaragaza neza cyane hamwe na viccoelastine neza.

Uburemere bwa molekile nurwego rwo gusimbuza: Uburemere bwa molekile nurwego rwo gusimbuza (ni ukuvuga umubare wamatsinda ya hydroxy wasimbutse kuri buri gice cya glucoxyl ni ibintu bibiri byingenzi bireba imitungo. Mubisanzwe, hydroxyithyll selile hamwe nuburemere bwo hejuru bwa molekani bufite uburemere bwiza nubushobozi bwo kwinuba, mugihe urwego rwo hejuru rwo gusimbuza ruzamura amazi no gutuza.

Ibintu bya fiziki bya hydroxyithyl selile
Bitewe n'imiterere yihariye, hydroxyAythyll selile igaragaza urukurikirane rw'ibintu byiza bya fimicoclatical:

Amazi yonyine: hydroxyyeryll selile irashonga byoroshye mumazi akonje namazi ashyushye kugirango akore igisubizo gisobanutse cyangwa gito. Inzira yacyo ntiyibasiwe cyane na PH agaciro kandi igakomeza guhagarara hejuru ya ph (mubisanzwe hagati ya 2 na 12).

Ubunini: HydroxyEthyll selile ifite ingaruka nziza mu gisubizo cy'amazi, kandi ubushobozi bwacyo bwijimye bugira ingaruka kuburemere bwa molekile, urwego rwo gusimbuza no kwibanda. Mugihe kwibanda kwiyongera, viscolity yibisubizo yiyongera cyane, bityo birakoreshwa cyane mumirima yinganda bisaba ibibari.

Igikorwa cyo hejuru: Kubera ko hydroxyyerthyl molekile ikubiyemo amatsinda ya hydrophilique na skeletobic skeletique, irashobora kugabanya impagarara zubutaka mubisubizo hanyuma werekane ibikorwa runaka. Uyu mutungo utuma ukoreshwa mubice, inka nizindi nzego, kandi birashobora guteza imbere amazi n'ibicuruzwa.

Guhagarara: HydroxyAythyl Cell Soleulose afite umutekano mwiza mu gisubizo cy'amazi, arashobora kurwanya ingaruka z'ibintu rusange n'umucyo, kandi birahagaze munsi ya aside na alkaline. Ntabwo izateshwa agaciro mikorobe nyinshi mu gisubizo gitangaje, ntabwo byoroshye kwangirika mugihe cyo kubika.

BiocompaTubishoboka n'umutekano: HydroxyAythyl Velilese ikoreshwa cyane mu biryo, kwisiga no kuvura no gukomoka kuri selile isanzwe kandi bikomeza uburozi buke nyuma yo guhindura imiti. Kurugero, ikoreshwa nkuwabyimbye kandi uhagaze mu biryo, nkumunyabwenge kandi wa emalulizer mu kwisiga, kandi nkumuhuza kandi ugenzurwa na matrix igenzurwa mubinini byimyiteguro ya farumasi.

Gutegura no gusaba
Gutegura HydroxyAythyl ubusanzwe bigabanywa intambwe eshatu: alkanalisation ya selile, yabyitwaraga, kwezwa no gukama. Ubwa mbere, selilese ifatwa muburyo bwa alkaline kugirango ikore amatsinda ya hydroxyl ya selile, hanyuma ajyanwa na Ethylene okiside ya Ethylene kugirango atange HydroxyIthyl selile. Hanyuma, ibicuruzwa byanyuma biboneka binyuze mu ntambwe nko kutabogama, kweza no gukama.

HydroxyAythy yakoreshejwe cyane mu bikoresho byo kubaka (nka cement mirtar), imiti ya buri munsi (nko kwisiga), kuvura sisitemu yo kurekura ibiyobyabwenge).

Hydroxyyeryl selile irakoreshwa cyane mumirima itandukanye kubera imiterere nziza yumubiri na shimi. Umwihariko w'imiterere n'imiterere bituma bituma bigira uruhare runini mu kubyimba, kuzenguruka, guhagarika, gushiraho firime no gukomera, kandi ni ibikoresho byingenzi byingenzi bya shimi.
