Intangiriro yibanze ya Hec na HPMC

HEC (HydroxyAythyl Cellulose) na HPMC (HYDROXYPropyl methylcellse) harimo ibidukikije bikunze gukoreshwa muri selile, bikoreshwa cyane mu nganda nyinshi. Ibi bikoresho byabaye ibikoresho byingenzi bikora bitewe numubiri nuburozi.

1. HEC (HydroxyAythyl Cellulose)

1.1 Imiterere y'ibanze n'imiterere
HEC ni polymer itari iolic y'amazi yabonetse kubishushanyo mbonera bya selile karemano. Imiterere yacyo yibanze ni intangiriro ya hydroxyyerltyl abasimbuye hydroxyyedl kuri β-d-glucose skeleti ya selile. Kubera hydrophiliti yitsinda rya hydroxyyerthyl muburyo bwayo, hec ifite ubwitonzi bwiza no kunyeganyega mumazi.

HEC yerekana ubuhanga bwiza, imiterere-film na Lubricity, kandi na Acide- na Alkali-irwanya kandi bafite biocompat nziza. Iyi mitungo ituma ingirakamaro cyane cyane, stabilizer hamwe numukozi wa firime muri sisitemu ya equeous. Byongeye kandi, HEC igisubizo gifite thixotropy nziza, ishobora kwerekana vicosi yo hejuru munsi yimbaraga zo gucika intege, kandi uruzitiro rutonyanga vuba ruyobowe n'imbaraga nyinshi. Ibi biranga bituma bifite agaciro gakoreshwa mubikorwa muburyo butandukanye.

1.2 Inzira yo Gutegura
HEC itegurwa cyane cyane no gutandukanya selile karemano. Mubisanzwe byakoreshejwe ibikoresho fatizo birimo inkomoko ya selile nka pamba nimbaho, bitwawe hamwe na etylene okiside ya alkalisare kugirango ibone hydroxyyerthyl selile. Mugihe cyuma kose, kugenzura imiterere yimyitwarire (nkubushyuhe, PH agaciro hamwe nigihe) bifite uruhare runini kurwego rwo gusimbuza, kwikebana no gusya ibicuruzwa byanyuma.

1.3 Gusaba
HEC ikoreshwa cyane mu bikoresho byo kubaka, amatara, imiti ya buri munsi, imiti n'ibiryo. Mu bikoresho byo kubaka, HEC ikoreshwa cyane muri sima na Gypsum nk'igituba cyiza no mu kigero cyo kunoza ibikorwa byayo no kurwanya imitungo yo kurwanya. Mu nganda zifata, HEC irashobora gukoreshwa nkababyimba no guhinduranya ibintu bishingiye ku mazi kugirango atezimbere ubupfura kandi bworoshye. Mu miti ya buri munsi nka shampoo n'intangarugero, hec ikoreshwa nka Thickener na Moisturizer gutanga ibicuruzwa kumva neza no gutuza. Byongeye kandi, mu nganda z'imiti n'ibiribwa, HEC ikoreshwa nk'agabumwe ku bisate, uwahoze ari filime uwahoze ari Capsules, kandi ari umubyimba w'akabiri mu biryo kubera ubuzima bwiza ndetse n'uburozi buke.

2. HPMC (HydroxyPropyl methylcellse)

2.1 Imiterere y'ibanze n'imiterere
HPMC ni selile itari ionic ether yabonetse mugutangiza hydroxyproppoppoppopy na memoxy muri skeleton. Bisa na Hec, HPMC ifite amazi meza, kubyimba, filime ikora imitungo na biocompat. Kubera uburyo na hydroxyProppoyl amatsinda yacyo muburyo bwayo, HPMC ntabwo ifite gusa ibikundwa gusa mumazi, ahubwo yagaragaje kandi ibikorwa bikomeye byo hejuru no guhagarika ibintu.

Ibyatsi byo gukemura HPMC bigira ingaruka cyane kubushyuhe. Mubushyuhe bumwe, viscozetity yo gukemura Hpmc igabanuka hamwe nubushyuhe. Byongeye kandi, HPMC ifite kandi imitungo myiza ya Gel. Iyo ubushyuhe bwigicuruzwa burenze agaciro runaka, gel izashyirwaho. Uyu mutungo ufite agaciro gakomeye gasaba mubice byibiribwa nubuvuzi.

2.2 Inzira yo Gutegura
Imyiteguro ya HPMC isa na wec, kandi nayo ikorwa binyuze muburyo bwa hahindutse selile. Mubisanzwe, react reacts ifite imyanda hamwe na methyl chloride mubihe bya alkaline kugirango itangire hydroxyproppeproppeppoppopy na memoxy, nibindi. Umutungo wa HPMC (nka viscosity, kukesha cyane na gel ubushyuhe) burashobora kugenzurwa neza muguhindura urwego rwo gusimbuza no kugenzurwa.

2.3 Gusaba
HPMC ifite uburyo butandukanye mubikorwa byubwubatsi, imiti, ibiryo n'imiti ya buri munsi. Mu bikoresho byo kubaka, HPMC ikoreshwa cyane muri sima, ibicuruzwa bya partar na gypsum nk'uburebure, kugumana amazi na binder kugirango bitezimbere imikorere yubwubatsi no kuramba byibikoresho. Mu rwego rw'ubuvuzi, HPMC ikoreshwa nk'abakozi bagenzuwe, ibikoresho byo gupfumukira kandi bya capsule ku bisate, bishobora kugarura neza ibiyobyabwenge, bikaba bishobora kugenzura neza ibiyobyabwenge, bishobora guteza ibiyobyabwenge. Mu nganda zibiribwa, HPMC ikoreshwa cyane nkumutwe hamwe na emalifiire mubicuruzwa bitetse, ibicuruzwa byamata hamwe no kunoza uburyo bwo kuzamura imiterere nuburyo bwo kunoza ibicuruzwa. Byongeye kandi, HPMC ikoreshwa cyane mumiti ya buri munsi nka Shampoo, gikingiwe, isuku yo mumaso, nibindi, Gutanga Ibicuruzwa Byinshi

Nkibintu bibiri byingenzi bya selile, Hec na HPMC bagira uruhare runini munganda nyinshi. HEC ikoreshwa cyane mubwubatsi, amatara, imiti nubuvuzi bwa buri munsi bitewe nubwinshi bwayo bwiza, filime na biocompat. HPMC, kurundi ruhande, igira uruhare runini mu kubaka, kuvura n'inganda ziterwa n'imitungo idasanzwe yo guhagarara no gusaba. Hamwe no gutera imbere ikoranabuhanga, inzira yo gutegura no gusaba imirima yibi bikoresho byombi izakomeza kwaguka, kuzana amahirwe yo guteza imbere inganda zijyanye.
