HPMC, cyangwa Hydroxypropyl Methyl Cellulose, ni ibikoresho byubaka byinshi kandi byingirakamaro byubaka byamamaye mumyaka yashize. Nkibikomoka kuri selile, HPMC ifite porogaramu kuva kwisiga kugeza kumavuta, kandi cyane cyane, yabonye inzira mubikorwa byubwubatsi nkibibyimbye, bifata, birinda colloid, emulifier na stabilisateur.
HPMC yo mu rwego rwubwubatsi ni polimeri yo mu rwego rwohejuru, ikabura amazi ikoreshwa mu bicuruzwa bitandukanye bya sima birimo amavuta ya tile, minisiteri, plaster, grout, hamwe na sisitemu yo hanze no kurangiza (EIFS). Imiterere yacyo itandukanye ituma iba igisubizo cyiza kubikorwa bishya byubaka no kuvugurura imishinga, kuko byongera imikoranire ihuza hamwe nibikoresho bitandukanye.
Kimwe mu byiza byingenzi bya HPMC nuburyo bwiza bwo gufata amazi. Ibi bivuze ko ishobora gufasha kugabanya umubare wamazi akenewe kubicuruzwa bishingiye kuri sima utiriwe utamba imitungo cyangwa imikorere yuruvange. Mugumana ubuhehere, birinda imvange gukama, bifasha kunoza imiterere nimbaraga zumusaruro wanyuma.
Byongeye kandi, HPMC ikora nka colloid ikingira, ifasha kugabanya ibyago byo gutandukana, guturika no kugabanuka mubikoresho bya sima. Ibi bituma byongerwaho ibicuruzwa bidahuye nikirere kibi cyangwa gikeneye kwihanganira imihangayiko myinshi.
Usibye iyi mikorere yongera imikorere, HPMC izwi cyane nkibikoresho biramba cyane. Ikozwe mubikoresho bishobora kuvugururwa, irashobora kwangirika kandi idafite uburozi, bigatuma ihitamo neza kububatsi bwangiza ibidukikije hamwe namasosiyete yubwubatsi.
Nibimenyetso byerekana ko bihindagurika, HPMC nayo ikoreshwa mugukora ibicuruzwa bishingiye kuri gypsumu nka stucco hamwe nuruvange. Muri iki kibazo, HPMC ifasha kunoza imikorere no guhuza imvange, mugihe kandi byongera imbaraga zubusabane hagati ya stucco na substrate.
Icyiciro cyubwubatsi HPMC iraboneka muburyo butandukanye bwimiterere nubunini buke, bituma ibikoresho bihuza nibisabwa byihariye. Ibi bituma ibintu bihinduka cyane bishobora gukoreshwa mubikorwa bitandukanye nibidukikije.
Mu gusoza, HPMC nigikoresho cyingenzi mubikorwa byubwubatsi kandi ibyiza byayo ni byinshi. Hamwe no gufata neza amazi, kurinda colloid hamwe nuburyo burambye, ni inyongera kandi ifite agaciro kubicuruzwa byose byubaka. Itezimbere imikorere, igabanya imyanda kandi nibyiza kububatsi bubungabunga ibidukikije hamwe namasosiyete yubwubatsi. Imikoreshereze ya HPMC iramurika ejo hazaza h'inganda zubaka.
