Ingaruka z'urwego rwo gusimbuza (DS) ku bwiza bwa HEC

HEC (hydroxyethyl selulose) ni polymer idafite ionic, ibora amazi-ikoreshwa cyane mu nganda zitandukanye nko kwita ku muntu ku giti cye, imiti, n'ibiribwa nk'umubyimba, uhuza, kandi uhamye. Urwego rwo gusimbuza (DS) ni ikintu gikomeye gishobora kugira ingaruka zikomeye kumiterere n'imikorere ya HEC.

Urwego rwo gusimbuza bivuga impuzandengo ya hydroxyethyl matsinda yometse kuri buri gice cya anhydroglucose yumugongo wa selile. Muyandi magambo, ipima urugero molekile ya selile yahinduwe hamwe na hydroxyethyl matsinda.

Ingaruka z'urwego rwo gusimbuza ubuziranenge bwa HEC ni ngombwa. Mubisanzwe, uko urwego rwo gusimburana rwiyongera, gukomera kwa HEC mumazi biriyongera, kandi ububobere bwayo bukagabanuka. HEC ifite urwego rwo hejuru rwo gusimbuza ifite ubukonje buke, kandi irashonga cyane mumazi. Ni ukubera ko amatsinda ya hydroxyethyl ahagarika hydrogene ihuza iminyururu ya selile, biganisha kumiterere ifunguye kandi yoroheje.

Byongeye kandi, urwego rwo hejuru rusimburwa rushobora kuzamura ubushyuhe bwumuriro wa HEC no kongera imbaraga zo kurwanya iyangirika ryimisemburo. Nyamara, urwego rwo hejuru rwo gusimburwa rushobora gutuma igabanuka ryibiro bya molekile no gutakaza imitungo yumwimerere yumugongo wa selile, bishobora kugira ingaruka kumikorere rusange ya HEC.

Muncamake, urwego rwo gusimburwa nikintu gikomeye gishobora kugira ingaruka zikomeye kumiterere n'imikorere ya HEC. Urwego rwo hejuru rusimburwa rushobora kunoza ubukana nubushyuhe bwa HEC, ariko urwego rwo hejuru rwo gusimburwa rushobora gutuma umuntu atakaza imitungo yambere yumugongo wa selile, bishobora kugira ingaruka kumikorere rusange ya HEC.
