Ni irihe tandukaniro riri hagati ya hydroxyethyl selulose na hydroxypropyl selile?

Hydroxyethylcellulose (HEC) na hydroxypropylcellulose (HPC) byombi bikomoka kuri selile, polymer karemano iboneka murukuta rw'ibimera. Izi nkomoko ya selile ikoreshwa cyane mu nganda zitandukanye kubera imiterere yihariye.

Imiterere ya shimi:

Hydroxyethylcellulose (HEC):

HEC ikomatanyirizwa mu gukora selile hamwe na okiside ya Ethylene.
Mu miterere yimiti ya HEC, amatsinda ya hydroxyethyl yinjizwa mumugongo wa selile.
Urwego rwo gusimbuza (DS) rugereranya impuzandengo yitsinda rya hydroxyethyl kumatsinda ya glucose murwego rwa selile.

Hydroxypropylcellulose (HPC):

HPC ikorwa no kuvura selile hamwe na okiside ya propylene.
Mugihe cyo gukora synthesis, hydroxypropyl matsinda yongewe kumiterere ya selile.
Kimwe na HEC, urwego rwo gusimburwa rukoreshwa mukugereranya urugero rwo gusimbuza hydroxypropyl muri molekile ya selile.

ibiranga:

Hydroxyethylcellulose (HEC):

HEC izwiho ubushobozi bwiza bwo gufata amazi, bigatuma iba ibintu bisanzwe muburyo butandukanye bwo kubyimba no gusya.
Ikora igisubizo gisobanutse mumazi kandi ikagaragaza imyitwarire ya pseudoplastique, bivuze ko itagaragara neza mugihe cyo guhangayika.
HEC isanzwe ikoreshwa mugutegura ibicuruzwa byita kumuntu, imiti, kandi nkibyimbye mumazi ashingiye kumazi.

Hydroxypropylcellulose (HPC):

HPC ifite kandi amazi meza yo gukemura no gukora firime.
Ifite intera nini yo guhuza hamwe na solve zitandukanye kuruta HEC.
HPC ikoreshwa kenshi nk'ibikoresho mu buhanga mu bya farumasi, ibicuruzwa byo mu kanwa, n'ibicuruzwa bya tablet.

gusaba:

Hydroxyethylcellulose (HEC):

Irakoreshwa cyane mubikorwa byo kwisiga no kwita kumuntu nkibyimbye muri shampo, amavuta yo kwisiga hamwe na cream.
Ikoreshwa nka stabilisateur na viscosity igenga imiti.
Ikoreshwa mugukora amarangi ashingiye kumazi no gutwikira.

Hydroxypropylcellulose (HPC):

Bikunze gukoreshwa mubikorwa bya farumasi, cyane cyane nkibihuza mugukora ibinini.
Ikoreshwa mubicuruzwa byita kumanwa nka menyo yinyo kugirango ubyibushye.
Irashobora gukoreshwa muri sisitemu yo gutanga ibiyobyabwenge bigenzurwa.

Mugihe hydroxyethyl selulose (HEC) na hydroxypropyl selulose (HPC) bisangiye bimwe bitewe ninkomoko yabyo ya selile, biratandukanye mumiterere yimiti, imiterere, nibisabwa. HEC ikunze gutoneshwa muburyo bwihariye bwo kwita no gufata neza uburyo bwo gufata amazi no kongera ubushobozi, mugihe HPC ikoreshwa cyane munganda zimiti, cyane cyane mubukora ibinini na sisitemu yo gutanga ibiyobyabwenge. Gusobanukirwa itandukaniro nibyingenzi muguhitamo ibikomoka kuri selile ikenewe mubikorwa byinganda.
