HPMC na HEMC ni polymers ebyiri zingenzi zakoreshejwe cyane mubikoresho byubwubatsi. Bafite uruhare runini mugutezimbere imikorere nubwiza bwibikoresho byubaka. Muri iyi ngingo, tuzamenyekanisha imitungo nibisabwa bya HPMC na HEMC mubikoresho byubwubatsi.
HPMC, izwi kandi ku izina rya hydroxypropyl methylcellulose, ni ether ya selile ikomoka ku biti no mu ipamba. Nimpumuro nziza, itaryoshye, ifu idafite uburozi ikemuka mumazi. HPMC ifite amazi meza yo kubika, kubyimba no kwigana emulisitiya, bigatuma iba inyongera ikunzwe mubikoresho byubwubatsi.
Imwe muma progaramu isanzwe kuri HPMC ni sima ishingiye kumatafari. HPMC irashobora kunoza imbaraga zububiko hamwe nakazi ko gufatira hamwe, kandi irashobora kandi kubuza amabati kunyerera cyangwa kugwa mugihe cyo kwishyiriraho. Byongeye kandi, HPMC irashobora kugabanya kwinjiza amazi ya tile, ningirakamaro kumara igihe kirekire no kuramba kwa tile.
HPMC nayo ikoreshwa cyane mubutaka bwa simaitike. Kwishyira hamwe-kwifashisha kuringaniza hasi ya beto itaringaniye, kandi HPMC irashobora kunoza urujya n'uruza rwimiterere. HPMC irinda kandi kwishyiriraho urwego rwo kwishyiriraho ibice no kugabanuka, bifite akamaro kubusugire bwa sisitemu yo hasi.
Ubundi buryo bwa HPMC ni sima-ishingiye kuri sima. HPMC irashobora kunoza gufatira hamwe no gukora bya plasta cyangwa stucco, kandi irashobora kandi kongera imikorere idakoresha amazi. Ibi nibyingenzi kurinda ibahasha yinyubako no kwirinda kwangirika kwubushuhe.
HEMC, izwi kandi nka hydroxyethyl methylcellulose, ni iyindi selulose ether ikoreshwa cyane mubikoresho byubaka. HEMC isa na HPMC mubijyanye nimikorere nibisabwa, ariko ifite ibyiza byihariye bituma ibera porogaramu zimwe.
Imwe mu nyungu zingenzi za HEMC nubwiza bwayo bwinshi. Ibi bituma biba byiza gukoreshwa mwikoti ryijimye hamwe n amarangi kugirango utezimbere kandi uringanize. HEMC ikoreshwa kandi cyane mumasafuriya hamwe na kashe, ishobora kunoza amazi no guhuza ibicuruzwa.
HEMC ikoreshwa kandi mubikoresho byubaka bishingiye kuri gypsumu nkibintu bifatanije hamwe na stucco. HEMC itezimbere imikorere noguhuza ibice hamwe kandi ikarinda kugabanuka no gucika. Byongeye kandi, HEMC irashobora kunoza uburyo bwo guhangana n’amazi no kurwanya indwara ya plasta, zifite akamaro kanini mu kirere cy’inyubako.
Mugusoza, HPMC na HEMC ni polymers ebyiri zingenzi hamwe nibisabwa byinshi mubikoresho byubwubatsi. Bafite uruhare runini mugutezimbere imikorere nubwiza bwibikoresho byubwubatsi kandi bifasha kurema inyubako ziramba, zikora neza kandi zirambye. Mugihe ibyo bikoresho bikomeje gutezwa imbere no kunonosorwa, turashobora gutegereza ibisubizo bishya kandi byubaka byubaka ejo hazaza.
