MHEC, cyangwa methylhydroxyethylcellulose, ninyongera yimiti ikoreshwa cyane mubikoresho byubaka. Cyane cyane mu gutwikira no kurangiza ibikoresho nka putty na plaster, uruhare rwa MHEC ni ingenzi cyane.
1. Imikorere ya MHEC muri putty
Putty ni ibikoresho bikoreshwa mukuzuza inkuta zingana cyangwa ubundi buso. Irakeneye kugira imikorere myiza yubwubatsi, imbaraga nigihe kirekire. Ikoreshwa rya MHEC muri putty ririmo ahanini ibi bikurikira:
a. Ingaruka
MHEC irashobora kongera cyane ubwiza bwa putty no kunoza imikorere yayo nubwubatsi. Ingaruka yibyibushye irashobora gufasha kugenzura imiterere ya putty, byoroshye kuyikoresha no kugumana umubyimba mwiza hejuru yubutumburuke butanyeganyega. Kubyimba neza birashobora kandi kunoza imikorere ya anti-sag ya putty, bigatuma kubaka byoroha.
b. Kubika amazi
MHEC ifite amazi meza, ni ingenzi kumikorere ya putty. Putty ifata igihe runaka kugirango yumuke kandi ikomere nyuma yo kuyisaba. Niba ubuhehere bwatakaye vuba, bizatera ubuso bwa putty kumeneka cyangwa guhinduka ifu. MHEC irashobora gukora firime igumana amazi muri putty kandi ikagabanya umuvuduko wamazi wamazi, bityo bigatuma ibyuma byuma byumye, bikagabanya imvune, kandi bikazamura ubwiza bwibicuruzwa byarangiye.
c. Kongera imbaraga
MHEC irashobora kunoza ifatizo rya putty, bigatuma irushaho gukomera kuri substrate zitandukanye. Ibi nibyingenzi muburyo butajegajega kandi burambye bwa putty layer. Kwizirika neza ntibishobora gusa kubuza gushira kugwa, ariko kandi byongera imbaraga zo guhangana ningaruka kandi bikongerera igihe cyakazi.
2. Imikorere ya MHEC muri gypsumu
Gypsum ni ibikoresho bisanzwe byubaka bifite imbaraga zo kurwanya umuriro n'ingaruka zo gushushanya. Uruhare rwa MHEC muri gypsumu ntirushobora kwirengagizwa. Ibintu nyamukuru byingenzi ni ibi bikurikira:
a. Kunoza imikorere yo gutunganya
MHEC itezimbere imitunganyirize ya plaster, byoroshye kuvanga no gukwirakwira. Muguhindura ibishishwa no guhora kwa gypsum, MHEC irashobora gufasha abakozi bubaka kugenzura neza ingano nubunini bwa gypsumu yakoreshejwe. Ibi nibyiza cyane kunoza imikorere yubwubatsi hamwe nuburinganire bwibicuruzwa byarangiye.
b. Kunoza guhangana
Plaster ikunda kugabanuka kumeneka mugihe cyo gukomera, bishobora kugira ingaruka kumiterere no mumikorere. Imikorere yo gufata amazi ya MHEC irashobora kugabanya umuvuduko ukabije w’amazi muri gypsumu, bikagabanya imitekerereze y’imbere, bityo bikagabanya kwandura. Byongeye kandi, MHEC irashobora kunoza imiterere ya plasta, bigatuma irwanya umuvuduko wo hanze.
c. Kunoza neza ubuso
Gukoresha MHEC muri gypsumu birashobora kandi kunoza ubuso bwayo kandi bigatuma isura yibicuruzwa bya gypsumu iba nziza cyane. Ubuso bunoze ntabwo bugira ingaruka nziza zo gushushanya gusa, ahubwo butanga urufatiro rwiza rwo gufatira amarangi, byorohereza inzira yo gushushanya.
Nkibyingenzi byingenzi byubaka, MHEC yerekana ibintu byinshi bisumba iyo bikoreshejwe muri putty na gypsum. Ntishobora gusa kunoza imikorere yubwubatsi, kunoza gufatira hamwe no kubika amazi yibikoresho, ariko kandi birashobora kunoza cyane kurwanya guhangana nubuziranenge bwibicuruzwa byarangiye. Iyi mitungo yatumye MHEC ikoreshwa cyane mubikorwa byubwubatsi, ihinduka igice cyingenzi cyibikoresho nka putty na plaster. Mu bihe biri imbere, hamwe niterambere ryikoranabuhanga ryubwubatsi no kunoza ibisabwa mubikorwa, ibyifuzo bya MHEC bizaba binini.
