I-MHEC (Methyl Hydroxyyethyl celtulese) kungenye i-polymer esekwe ku-cellulose evame ukusetshenziswa njengezengezo kuhlelo lokusebenza olususelwa kuthusi. Inezinzuzo ezifanayo ku-HPMC, kepha inomehluko othile kwizakhiwo. Lokhu okulandelayo ukusetshenziswa kwe-MHEC kuma-Plasters aqinisekisiwe:
Ukugcinwa kwamanzi: I-Mhec inyusa ukugcinwa kwamanzi engxenyeni yokubumba, ngaleyo ndlela yandisa ukuwela. Kuyasiza ukuvikela le ngxube ekumiseni ngaphambi kwesikhathi, okuvumela isikhathi esanele sokwenza isicelo nokuqeda.
Ukusetshenziswa: I-MHEC ithuthukisa ukusebenziseka nokusakazeka kwezinto zokufaka. Kuthuthukisa ukuhlangana kabusha nokugeleza, okwenza kube lula ukufaka isicelo futhi kufinyelelwe ukuqedwa okubushelelezi ezindaweni ezikhona.
I-Adhesion: I-Mhec igqugquzela ukunamathela okungcono kodaka olungaphansi. Kuyasiza ekuqinisekiseni isibopho esiqinile phakathi kosonga kanye nendawo engaphansi, ukunciphisa ubungozi bokuhlehlisa noma ukwahlukana.
Ukumelana kwe-SAG: I-Mhec ifaka i-Thixotropy engxube yengxubevange yengxubevange yengxubevange yayo, ithuthukisa ukumelana kwayo ku-SAG noma i-slump lapho isetshenziswa ngokuqondile noma ngaphezulu. Kuyasiza ukugcina ubukhulu obufunayo nokwakheka kodaka ngesikhathi sohlelo lokusebenza.
Ukumelana nokuqhekeka: Ngokungeza i-Mhec, izinto ezibumbayo zithola ukuguquguquka okuphezulu futhi ngaleyo ndlela kuthuthukiswe ukuqhekeka kokuqhekeka. Kuyasiza ukunciphisa ukwenzeka kwemifantu okubangelwa ukomisa i-shrinkage noma ukwanda kwe-thermal.
Ukuqina: I-Mhec inikela ekunciphiseni kohlelo lokubumba. Kwakha ifilimu evikelayo lapho eyomile, eyandayo yokumelana nokungena kwamanzi, isimo sezulu kanye nezinye izinto zemvelo.
Ukulawulwa kwe-Rheelogy: I-Mhec isebenza njengesiguquli se-Rheology, okuthinta ukugeleza nokusebenza kwengxubevange. Kuyasiza ukulawula ukubonana, kuthuthukisa ukupompa noma ukufafaza izici, futhi kuvimbela ukuxazulula noma ukwahlukanisa kwezinhlayiya eziqinile.
Kumele kuqashelwe ukuthi inani elithile nokukhethwa kwe-MHEC kungahluka ngokuya ngezidingo ezithile zohlelo lokubumba, njengokuqina okudingekayo, izimo zokulapha nezinye izinto. Abakhiqizi bavame ukuhlinzeka ngemihlahlandlela kanye namashidi wedatha yezobuchwepheshe ngamazinga anconyiwe okusetshenziswa nemiyalo yokufaka i-MHYPS enezinhlamvu ze-gypsum.
