Skim coating ni uburyo buzwi bwo kugera ku buryo bworoshye, ndetse no hejuru kurukuta no hejuru. Tekinike ikubiyemo gukoresha urwego ruto rwa minisiteri cyangwa stucco hejuru yubuso cyangwa butaringaniye kugirango habeho urwego rusize irangi cyangwa wallpaper. HPMC cyangwa hydroxypropyl methylcellulose nikintu gikoreshwa cyane mubyimbye bivanze. Reka turebe neza ibyiza bya HPMC mubice bito.
Ubwa mbere, HPMC ni umubyimba mwiza cyane wo gushira kuko ni amazi ashonga kandi byoroshye kuvanga. Bitandukanye nibindi binini nka tapioca krahisi cyangwa ifu y ingano, HPMC ishonga rwose mumazi, bigatuma byoroha kugera kumiterere ihamye ivanze na skim. Mubyongeyeho, HPMC ifite adhesion nziza, ifasha putty gukomera kuri substrate kandi ikarinda gucika.
Iyindi nyungu ikomeye yo gukoresha HPMC muruvange rwa putty ni ubushobozi bwayo bwo kunoza imikorere no gutembera. Kuberako HPMC igenda yiyongera ivangavanze, iha plasteri umwanya munini wo gukora kumurongo wa putty mbere yuko ishyiraho. Na none, ibi bituma byoroha, birenze ndetse no gusaba. Mubyongeyeho, HPMC itezimbere imiterere iringaniza ya putty, ikayemerera kurwego-rwuzuye no kuzuza ubusembwa buto muri substrate.
HPMC nayo ni ibidukikije byangiza ibidukikije kuburyo bworoshye. Nibicuruzwa bya selile, ni biodegradable kandi ntabwo ari uburozi. Ibi bivuze ko HPMC nta ngaruka mbi zangiza ku bidukikije cyangwa ku buzima bwabantu. Byongeye kandi, HPMC itezimbere kuramba kugabanya imyanda no kwirinda gusana cyane cyangwa kuyisimbuza.
Hanyuma, HPMC irahendutse kandi irahari henshi. Yakozwe cyane kandi igurishwa ku isoko ryisi yose, bigatuma igera kubabikora ndetse nabakoresha-nyuma. HPMC ifite kandi igihe kirekire cyo kubaho, bivuze ko ishobora kubikwa igihe kirekire idatakaje ubuziranenge cyangwa imikorere.
Mu gusoza, HPMC niyimbye ryiza cyane ivanze. Itanga inyungu zinyuranye zirimo kunoza imikorere, gutembera, kuringaniza no gufatira hamwe. Mubyongeyeho, ni ibidukikije byangiza ibidukikije, bidahenze kandi bifite porogaramu zitandukanye. Nkibyo, HPMC nuguhitamo gukundwa kubantu bose bashya hamwe nabapompa babimenyereye bashaka kugera kubintu byiza, ndetse no hejuru kurukuta no hejuru.
