I-Methylhydroxyethylcellulose (MHEC) iyisengezo esisetshenziswa kakhulu ezintweni esekwe usimende njengodaka nokhonkolo. Ingowomndeni wama-cellulose ethers futhi ikhishwa ku-cellulose yemvelo ngenqubo yokuguqulwa kwamakhemikhali.
I-MHEC isetshenziswa ngokuyinhloko njenge-thickener, i-ejenti yokugcina amanzi kanye ne-rheology modifier emikhiqizweni esekwe usimende. Kuyasiza ukuthuthukisa ukusebenza kanye nokuvumelana kwezingxube zikasimende, okwenza kube lula ukuphatha ngesikhathi sokwakha. I-MHEC iphinde inikeze ezinye izinzuzo ezimbalwa, kufaka phakathi:
Ukugcinwa kwamanzi: I-MHEC inamandla okugcina amanzi, okuvimbela ukomiswa ngaphambi kwesikhathi kwezinto ezisekelwe kusimende. Lokhu kuwusizo ikakhulukazi ezindaweni ezishisayo, ezomile noma lapho amahora okusebenza engeziwe edingeka.
Ukunamathela Okuthuthukisiwe: I-MHEC ithuthukisa ukunamathela phakathi kwezinto ze-cementitious nezinye izinto ezingaphansi ezifana nezitini, itshe noma i-tile. Kuyasiza ukuthuthukisa amandla ebhondi futhi kunciphisa amathuba okuthi i-delamination noma ukuhlukana.
Isikhathi Esandisiwe Sokuvula: Isikhathi sokuvula inani lesikhathi udaka noma ingcina ehlala isetshenziswa ngemva kokwakhiwa. I-MHEC ivumela isikhathi eside esivulekile, evumela izikhathi ezinde zokusebenza kanye nesimo esingcono sezinto ngaphambi kokuba ziqine.
Ukumelana Ne-Sag Okuthuthukisiwe: Ukumelana ne-Sag kubhekisela ekhonweni lezinto ezikwaziyo ukumelana nokwehla okuqondile noma ukuwohloka lapho kusetshenziswa endaweni eqondile. I-MHEC ingathuthukisa ukumelana kwe-sag kwemikhiqizo esekwe usimende, iqinisekise ukunamathela okungcono nokunciphisa ukuguquguquka.
Ukusebenza okuthuthukisiwe: I-MHEC iguqula i-rheology yezinto ezisekelwe kusimende, ithuthukise ukugeleza nokusabalala kwazo. Isiza ukuzuza ukuhlanganisa okushelelayo nokungaguquguquki, okwenza kube lula ukuphatha nokusebenzisa.
Isikhathi Sokusetha Esilawulwayo: I-MHEC ingathonya isikhathi sokusetha sezinto ezisekelwe kusimende, okuvumela ukulawula okukhulu phezu kwenqubo yokuphulukisa. Lokhu kuwusizo ikakhulukazi ezimeni lapho izikhathi zokusetha ezinde noma ezimfushane zidingeka.
Kufanele kuqashelwe ukuthi izakhiwo ezithile kanye nokusebenza kwe-MHEC kungase kuhluke kuye ngesisindo sayo samangqamuzana, izinga lokushintshwa, nezinye izici. Abakhiqizi abahlukene banganikela ngemikhiqizo ye-MHEC enezici ezihlukile ukuze ivumelane nezinhlelo zokusebenza ezithile.
Sekukonke, i-MHEC iyisengezo semisebenzi eminingi engathuthukisa ukusebenza nokucutshungulwa kwezinto ezisekelwe kusimende, enikeza izinzuzo ezifana nokunamathela okuthuthukisiwe, ukugcinwa kwamanzi, ukumelana ne-sag kanye nesikhathi sokusetha esilawulwayo.
