I-Methylhydroxyethylcellulose (MHEC) yinto eyongeziweyo esetyenziswa ngokuqhelekileyo kwizinto ezisekelwe kwi-samente ezifana nodaka kunye nekhonkrithi.Iphuma kwintsapho ye-cellulose ethers kwaye ikhutshwe kwi-cellulose yendalo ngokusebenzisa inkqubo yokuguqulwa kweekhemikhali.
I-MHEC isetyenziswe ngokuyinhloko njenge-thickener, i-agent egcina amanzi kunye ne-rheology modifier kwiimveliso ezisekelwe kwi-samente.Inceda ukuphucula ukusebenza kunye nokuhambelana kwemixube yesamente, okwenza kube lula ukuphatha ngexesha lokwakha.I-MHEC ikwabonelela nezinye izibonelelo ezininzi, kubandakanya:
Ukugcinwa kwamanzi: I-MHEC inamandla okugcina amanzi, okuthintela ukomiswa kwangaphambili kwezinto ezisekelwe kwi-samente.Oku kuluncedo ngakumbi kwimozulu eshushu, neyomileyo okanye xa iiyure zokusebenza ezongeziweyo zifuneka.
Ukuphuculwa kwe-Adhesion: I-MHEC iphucula ukudibanisa phakathi kwezinto ze-cementitious kunye nezinye i-substrates ezifana nezitena, ilitye okanye i-tile.Inceda ekuphuculeni amandla ebhondi kwaye inciphisa ukubakho kokwahlulwa okanye ukwahlukana.
Ixesha elongeziweyo lokuvula: Ixesha lokuvula lixa lexesha udaka okanye i-adhesive ihlala isetyenziswa emva kokwakhiwa.I-MHEC ivumela ixesha elide elivulekileyo, livumela ixesha elide lokusebenza kunye nokulungiswa okungcono kwezinto eziphathekayo ngaphambi kokuba kuqiniswe.
Ukuxhathisa kwe-Sag okomeleziweyo: Ukumelana ne-Sag kubhekiselele ekukwazini kwemathiriyeli ukuxhathisa ukudilika ngokuthe nkqo okanye ukugoba xa isetyenziswa kumphezulu othe nkqo.I-MHEC inokuphucula ukuxhathisa kwe-sag yeemveliso ezisekelwe kwi-samente, ukuqinisekisa ukunamathela okungcono kunye nokunciphisa ukuguqulwa.
Ukusebenza okuphuculweyo: I-MHEC iguqula i-rheology yezinto ezisekelwe kwi-samente, ukuphucula ukuhamba kwazo kunye nokusabalalisa.Inceda ukufezekisa ukudibanisa okulula kwaye okuhambelanayo, okwenza kube lula ukuphatha nokusebenzisa.
Ixesha lokumisela eliLawulwayo: I-MHEC inokuchaphazela ixesha lokumisela izinto ezisekelwe kwi-samente, okuvumela ukulawula okukhulu kwinkqubo yokunyanga.Oku kuluncedo ngakumbi kwiimeko apho kufuneka ixesha elide okanye elifutshane lokuseta.
Kufuneka kuqatshelwe ukuba iipropati ezithile kunye nokusebenza kwe-MHEC kunokuhluka ngokuxhomekeka kwisisindo se-molecular, iqondo lokutshintshwa, kunye nezinye izinto.Abavelisi abahlukeneyo banokunika iimveliso ze-MHEC ezineempawu ezahlukeneyo ukuze zihambelane nezicelo ezithile.
Ngokubanzi, i-MHEC yongezelela izinto ezininzi ezinokuphucula ukusebenza kunye nokuqhutyelwa kwezinto ezisekelwe kwi-samente, ezinikezela ngeenzuzo ezifana nokubambelela okuphuculweyo, ukugcinwa kwamanzi, ukuchasana kwe-sag kunye nexesha lokumisela elilawulwayo.
