Ubusanzwe Polymer HydroxyPropyl Methylcellse kuri sima ishingiye kuri plaster

HydroxyPropyl MethylcellALese (HPMC) ni polymer karemano ikoreshwa cyane mu nganda zubwubatsi nka claster ishingiye kuri sima. Irashobora gukoreshwa nkabakozi bagumana namazi, ubumwe, na Binder kugirango batezimbere imikorere yimpapuro za sima.

HPMC ni igice cya kabiri cya enterineti, gukosora amazi yakozwe muri selile. Bikomoka kuri selile karemano binyuze muburyo bwo guhindura imiti bukubiyemo kongeramo amatsinda ya hydroxyProppopy na methyl. Uku guhindura ibisubizo muri polymer hamwe namazi yoroshye, ituze ryumuriro, no kurwanya imiti.

Gukoresha HPMC muri plaster ishingiye kuri sima zitanga inyungu nyinshi nka:

1. Igikorwa cyanonosowe: HPMC ikora nkimyitwarire yuburyo butezimbere ibikorwa nibisabwa bya plaster. Yongera imbaraga, guhuriza hamwe, no gukwirakwiza plaster, kubyemerera gukoreshwa byoroshye.
2. Gufunzwe kw'amazi: HPMC irashobora gukuramo no kugumana amazi menshi, afasha gukumira plaster gutuka vuba. Uyu mutungo kandi ubyemeza ko plaster ikomeza guhuzagurika no gukora akazi mugihe kirekire, ndetse no mubihe bishyushye kandi byumye.
3. Kongera ubumwe no kumeneka: HPMC ikora film hafi ya sima, yongera ubumwe no gusohora subsite. Uyu mutungo wemeza ko plaster ikomeje kuba idakomeza kandi idacika cyangwa itandukanye na substrate.
4. Yagabanutseho: HPMC itezimbere imbaraga za tensile na guhinduka ya plaster, kugabanya amahirwe yo guturika kubera kugabanuka cyangwa kwaguka.
5. Iterambere rirashimishije: HPMC itanga plaster hamwe no kurwanya amazi yanoze hamwe no kurwanya imiti, bigatuma biramba kandi birwanya uburere no gusaza.

Usibye izo nyungu, HPMC nayo ni inshuti zirambye kandi zangiza ibidukikije zishobora gufasha kugabanya ingaruka zishingiye ku bidukikije. Ntabwo ari uburozi, bizima, kandi ntirekura ibintu byangiza ibidukikije.

Gukoresha HPMC muri plasset-claster ishingiye kubice, nikongerwaho imvange yumye ya sima n'umucanga mbere yo kongera amazi. Urupapuro rusabwa rwa HPMC iratandukanye bitewe na porogaramu yihariye hamwe nibiranga plaster. Mubisanzwe, dosiye ya 0.2% kuri 0.5% ya HPMC ishingiye kuburemere bwa sima n'umucanga.

HPMC ni ikintu kinyuranye kandi cyiza gishobora kunoza cyane imikorere ya sima ishingiye kuri sima. Inkomoko karemano, irambye, kandi urugwiro rutuma habaho amahitamo meza kuba rwiyemezamirimo, abubatsi, no kubaka ba nyir'ubwite bashyira mubikorwa ibikorwa birambye byubaka.
