Polymer Kamere Hydroxypropyl Methylcellulose Kuri Sima ishingiye kuri plaque
Hydroxypropyl methylcellulose (HPMC) ni polymer karemano yakoreshejwe cyane mu nganda zubaka nk'inyongeramusaruro ishingiye kuri sima. Irashobora gukoreshwa nkibikoresho byo kubika amazi, kubyimbye, no guhambira kunoza imikorere ya plaque ishingiye kuri sima.
HPMC nigice cya sintetike, polymer-soluble polymer ikozwe muri selile. Bikomoka kuri selile karemano binyuze muburyo bwo guhindura imiti ikubiyemo kongeramo hydroxypropyl na methyl. Ihinduka ritanga polymer hamwe nogutezimbere kwamazi, guhagarara neza, hamwe no kurwanya imiti.
Gukoresha HPMC muburyo bwa sima bushingiye kumashanyarazi bitanga inyungu nyinshi nka:
- Kunoza Imikorere: HPMC ikora nkimpinduka ya rheologiya itezimbere imikorere nibikorwa bya plaster. Itezimbere, gufatanya, no gukwirakwiza plaster, ikemerera gukoreshwa byoroshye kuri substrate.
- Gufata neza Amazi: HPMC irashobora gukurura no kugumana amazi menshi, ifasha kurinda plaster gukama vuba. Uyu mutungo kandi uremeza ko plaster ikomeza guhoraho no gukora mugihe kirekire, ndetse no mubihe bishyushye kandi byumye.
- Kwiyongera kwa Cohesion na Adhesion: HPMC ikora firime ikikije uduce twa sima, ibyo bikaba byongera ubumwe bwabo hamwe no gufatira kuri substrate. Uyu mutungo uremeza ko plaster ikomeza kuba ntamakemwa kandi ntigucike cyangwa ngo itandukane na substrate.
- Kugabanuka Kumeneka: HPMC itezimbere imbaraga zingirakamaro hamwe nubworoherane bwa plasta, bikagabanya amahirwe yo guturika bitewe no kugabanuka cyangwa kwaguka.
- Kuramba kuramba: HPMC itanga plaster hamwe n’amazi meza yo kurwanya amazi no kurwanya imiti, bigatuma iramba kandi ikarwanya ikirere no gusaza.
Usibye izo nyungu, HPMC ninyongeramusaruro irambye kandi yangiza ibidukikije ishobora gufasha kugabanya ingaruka z’ibidukikije ziterwa na sima. Ntabwo ari uburozi, ibinyabuzima, kandi ntibirekura ibintu byangiza ibidukikije.
Gukoresha HPMC muri plaque ishingiye kuri sima, mubisanzwe byongewe kumvange yumye ya sima n'umucanga mbere yo kongeramo amazi. Igipimo gisabwa cya HPMC kiratandukanye bitewe na progaramu yihariye hamwe nibintu byifuzwa bya plaster. Mubisanzwe, birasabwa urugero rwa 0.2% kugeza 0.5% ya HPMC ukurikije uburemere bwa sima n'umucanga.
HPMC ninyongera kandi yingirakamaro ishobora kuzamura imikorere yimikorere ya sima. Inkomoko yabyo, irambye, hamwe n’ibidukikije byangiza ibidukikije bituma ihitamo neza kubasezerana, abubatsi, hamwe naba nyiri inyubako bashyira imbere ibikorwa byubaka birambye.
