Hydroxyyeryl selile (hec) ni polymer itari ionic, polymer ifata amazi akomoka kuri selile. Bikoreshwa cyane mu nganda zitandukanye, harimo no kumenza, aho bikora nk'abakozi bijimye, imirasire y'amashanyarazi, na stabilizeri. Ubushobozi bwa hec bwo kuzamura viscolity yo kumera ni ngombwa kubisabwa byinshi, tubisaba kubisabwa bikwiye, gukora, no kuramba byibicuruzwa.
Imitungo ya hydroxyyeryl selile
HEC ikorwa mu gufatanya na selile oxide oxide iyobowe na alkaline, bikaviramo polymer ifite amatsinda ya hydroxyerythyl afatanye na selile. Urwego rwo gusimbuza (DS) hamwe no gusimbuza umuryango (MS) nibipimo byingenzi bigira ingaruka kumitungo ya Hec. DS bivuga impuzandengo yitsinda rya hydroxyl kuri molekile ya selile yasimbuwe nitsinda rya hydroxyyerthyl, mugihe ms yerekana umubare wikigereranyo cya Moles oxide yabyakiriye hamwe na mole ya anhyglucocose muri selile.
HEC irangwa no gukemuwe mumazi, gukora ibisubizo bisobanutse kandi bisobanutse hamwe na viso ndende. Ukugaragara kwayo kwatewe nibintu byinshi, harimo uburemere bwa molekile, kwibanda, ubushyuhe, na ph of igisubizo. Uburemere bwa molekile ya HEC irashobora gutandukana kuva hasi kugeza hejuru cyane, yemerera gushyiraho ibihumanya bifite ibisabwa bitandukanye.
Uburyo bwo kuzamura vicosity
Hydration no kubyimba:
HEC yongera visosity viscosity cyane cyane kubushobozi bwayo bwo kuva cyangwa kubyimba mumazi. Iyo Hec yongeweho kumugaragaro afatika, amatsinda ya hydroxyyerytyl akurura molekile y'amazi, yerekeza ku kubyimba iminyururu ya polymer. Uku kubyimba byongera igisubizo igisubizo gutemba, bityo rero byongera urujijo. Igihe cyo kubyimba hamwe na vino yavuyemo biterwa na polymer kwibanda hamwe nuburemere bwa molekile ya hec.
Molekori Yitaweho:
Mu gisubizo, HEC Polymers ihura nazo kubera imiterere yabo ndende. Uku kwizirikana gukora umuyoboro uhagarika urujya n'uruza rw'i molekile mu rupfu, bityo ukongera urujijo. Uburemere bwo hejuru bwa moleclar hec bivamo ubwitonzi bukomeye kandi bukomeye. Urwego rwo kwishora rushobora kugenzurwa no guhindura Polymer kwibanda hamwe nuburemere bwa molekile ya hec yakoresheje.
Amarira ya Hydrogen:
HEC irashobora gukora hydrogen ingwate hamwe na molekile y'amazi nibindi bigize muri forelation. Izi mbuto za hydrogen zigira uruhare muri viscosity mukora umuyoboro wubatswe mubisubizo. Amatsinda ya hydroxyyerythyl kuri selile ya selile yongera ubushobozi bwo gukora amashanyarazi ya hydrogen, arushijeho kongera viscosiya.
Imyitwarire ya Oarning:
HEC yerekana imyitwarire yoroheje, bivuze ko vicosi yayo igabanuka munsi yo guhagarika umutima. Uyu mutungo mwiza mugutanga amakuru kuko yemerera porogaramu byoroshye munsi ya Shear (nko gukwirakwiza cyangwa koza) mugihe ukomeje kuba vicosi ndende mugihe kuruhuka, kwemeza imikorere myiza no gushikama. Imyitwarire yoroheje ya Hec yitirirwa guhuza iminyururu ya polymer mu cyerekezo cy'imbaraga zikoreshwa, kugabanya by'agateganyo by'agateganyo.
Porogaramu mumyitozo ngororamubiri
Amazi ashingiye ku meza:
HEC ikoreshwa cyane mumazi ashingiye kumazi, nk'abo bagenewe impapuro, imyenda, n'ibiti. Ubushobozi bwayo bwo kubyimba no gutuza aho bifatika bituma ikomeza kuvanga rimwe kandi byoroshye gusaba. Mu mpapuro no gupakira impinja, HEC itanga viscosity ikenewe kugirango ikoreshwe neza kandi iganike.
Ibyingenzi:
Mubwubatsi, nkibi bikoreshwa mugushiraho ibihangano cyangwa igipfukisho cyintambara, HEC yongera viscosiya, kuzamura ibikorwa bifatika na sag. Igikorwa cya Chickening cya HEC cyemeza ko umurego umanuka mugihe cyo gusaba kandi gishyiraho neza, gitanga ubumwe bukomeye kandi burambye.
Kwiyongera no kwita ku muntu ku giti cye:
HEC ikoreshwa no mu bicuruzwa bitangaje kandi byita ku giti cye bisaba imitungo ifatika, nko mu kayira keza gakeye hamwe na masike yo mumaso. Muri ibi bikorwa, hec itanga ubukana neza kandi bumwe, kuzamura imikorere yimikorere nubunararibonye bwabakoresha.
Ibikorwa by'imiti:
Mu nganda za farumasi, hec ikoreshwa mu gace ka transdermal hamwe na sisitemu yo gutanga ibiyobyabwenge aho hantu hateganijwe hashingiwe ku rubanda rw'imikorere ifatika. HEC iremeza ko urwego rufatika rurahumanya, rutanga ibiyobyabwenge bihamye no gukurikiza uruhu.
Ibintu bireba kuzamura vicosity
Kwibanda:
Kwibanda kuri Hec muburyo bubi bugereranywa na viscosity. Ibitekerezo Byinshi bya Hec Bitewe na Vioscosity kubera imikoranire ikomeye ya polymer Ariko, kwibanda cyane birashobora gutera ifatwa ningorabahizi mugutunganya.
Uburemere bwa molekile:
Uburemere bwa molekile ya Hec nikintu gikomeye muguhitamo vicosity yo kumeneka. Ibiro byo hejuru bya moleclar Hec itanga ubushyuhe bwo hejuru kuri concentration yo hepfo ugereranije na molecular uburemere bwa molecular. Guhitamo uburemere bwa molekile biterwa na virusi yifuzwa hamwe nibisabwa.
Ubushyuhe:
Ubushyuhe bugira ingaruka kuri viscosity yibisubizo bya hec. Mugihe ubushyuhe bwiyongera, viscosity mubisanzwe iragabanuka kubera kugabanuka muri hydrogène ihuza no kongera ubumuga bwa molecular. Gusobanukirwa umubano wubushyuhe nibyingenzi kubisabwa byerekanwe nubushyuhe butandukanye.
PH:
PH ya formetive forelation irashobora guhindura viscosity ya Hec. HEC irahagaze hejuru ya PH nini, ariko ibintu bikabije PH birashobora kuganisha ku mpinduka mumiterere ya polymer no kureba. Gutegura ibifatika mubitekerezo bya PH Qumimal byemeza imikorere ihamye.
Ibyiza byo gukoresha hydroxyyeryl selile
Kamere NTABIRI:
Kamere itari ionic ya hec itumvikana muburyo butandukanye bwibindi bigize, harimo nabandi polymer, ibisasu, na electrolytes. Ihuriro ryemerera gufata ibintu bifatika.
Biodegradabletable:
Hec ikomoka kuri selile, ibikoresho bisanzwe kandi bishobora kongengwa. Ni Biodegradament, igahitamo abagenzi ibidukikije kugirango amenyere. Gukoresha bihuza hamwe nibisabwa bigenda byiyongera kubicuruzwa birambye kandi byangiza ibidukikije.
Guhagarara:
HEC itanga umutekano mwiza wo gufata amashusho, gukumira gutandukana no gutura mubice bihamye. Uku gutuma amaso akomeje gukora neza mubuzima bwayo no mugihe cyo gusaba.
Imiterere ya firime:
HEC ikora firime zitoroshye kandi ziboneye kuruma, ningirakamaro mugukoresha porogaramu isaba umurongo usobanutse kandi uhindagurika. Uyu mutungo ni ingirakamaro cyane muri porogaramu nka Labels na kaseti.
Hydroxyyeryl selile igira uruhare rukomeye mu rwego rwo kuzamura ubuyonguzi ku buryo bwo kumenyekana binyuze mu buryo bwo kurya no kubyimba, kwifuza, kunanga kw'imisozi, n'imyitwarire ya hydrogen. Imitungo yayo, harimo naturike, idafite imiterere, biodegrafiya, hamwe nubushobozi bwa firime, bikaba guhitamo neza kubisabwa bitandukanye. Gusobanukirwa ibintu bigira ingaruka zo kuzamura vic, nko kwibanda, uburemere bwa molecular, ubushyuhe, na ph, yemerera abamubutumwa guhuza ibicuruzwa bifatika kugirango byubahirize ibisabwa. Nk'inganda zikomeje gushaka ibikoresho birambye kandi byo hejuru, HEC ikomeje kuba ikintu cyagaciro mu gushyiraho ibicuruzwa byateye imbere.
