I-MHEC (i-Methyl Hydroxyethyl Cellulose) yenye i-polymer esekwe kwi-cellulose esetyenziswa ngokuqhelekileyo njenge-additive kwi-cement-based rendering applications.Ineenzuzo ezifanayo kwi-HPMC, kodwa inomahluko othile kwiipropati.Oku kulandelayo kukusetyenziswa kwe-MHEC kwiiplasta zesamente:
Ukugcinwa kwamanzi: I-MHEC ikwandisa ukugcinwa kwamanzi kumxube wokutyabeka, ngaloo ndlela ukwandisa ukusebenza.Inceda ukuthintela umxube ukuba wome ngaphambi kwexesha, ukuvumela ixesha elaneleyo lokufaka isicelo kunye nokugqiba.
Ukusebenza okusebenzayo: I-MHEC iphucula ukusebenza kunye nokusasazeka kwezinto zokutyabeka.Iphucula ubumbano kunye neempawu zokuhamba, okwenza kube lula ukusebenzisa kunye nokufezekisa ukugqiba okugudileyo kwimigangatho.
Ukubambelela: I-MHEC ikhuthaza ukunamathela okungcono kwe-plaster kwi-substrate.Inceda ekuqinisekiseni ibhondi eyomeleleyo phakathi kwe-plaster kunye nomgangatho ongaphantsi, ukunciphisa umngcipheko we-delamination okanye ukuhlukana.
I-Sag Resistance: I-MHEC inika i-thixotropy kumxube we-plaster, ukuphucula ukuchasana kwayo kwi-sag okanye i-slump xa isetyenziswe ngokuthe nkqo okanye ngaphezulu.Inceda ukugcina ubukhulu obufunwayo kunye nokumila kwe-plaster ngexesha lokufaka isicelo.
Ukumelana nokuqhekeka: Ngokongeza i-MHEC, izinto zokutyabeka zifumana ukuguquguquka okuphezulu kwaye ngaloo ndlela kuphuculwe ukumelana nokuqhekeka.Inceda ukunciphisa ukwenzeka kokuqhekeka okubangelwa ukomisa ukuncipha okanye ukwandiswa kwe-thermal/contraction.
Ukuqina: I-MHEC inegalelo ekomelezeni kwenkqubo yokutyabeka.Yenza ifilimu ekhuselayo xa yomile, ukwandisa ukuchasana nokungena kwamanzi, isimo sezulu kunye nezinye izinto ezisingqongileyo.
Ulawulo lweRheology: I-MHEC isebenza njenge-rheology modifier, echaphazela ukuhamba kunye nokusebenza komxube wokunikezela.Inceda ukulawula i-viscosity, iphucula ukupompa okanye ukutshiza iimpawu, kunye nokuthintela ukuhlalisa okanye ukuhlukana kweengqungquthela eziqinileyo.
Kufuneka kuqatshelwe ukuba inani elithile kunye nokukhethwa kwe-MHEC kunokwahluka ngokuxhomekeke kwiimfuno ezithile zenkqubo yokutyabeka, njengobunzima obufunekayo, iimeko zokunyanga kunye nezinye izinto.Abavelisi bahlala bebonelela ngezikhokelo kunye namaphepha edatha yezobugcisa kunye namanqanaba acetyiswayo okusetyenziswa kunye nemiyalelo yokubandakanya i-MHEC kwiifom ze-samente ze-gypsum.
