I-MHEC, noma i-Methyl Hydroxyethyl Cellulose, iyinhlanganisela eguquguqukayo eye yasetshenziswa ezinhlobonhlobo zezimboni, kodwa isetshenziswa kakhulu embonini yodaka oluxubekile. Ama-dry-mix motars ayingxube eyimpuphu yama-mineral aggregates kanye nezinto ezibophayo ezingaxutshwa namanzi ukuze zakhe unamathisele wezinto ezihlukahlukene zokwakha ezifana nokupulasitela, ukupulasitela kanye nokufaka amathayela.
I-MHEC iyisengezo esithuthukisa ukusebenza nokusebenza kwemikhiqizo yodaka olomile ngokuthuthukisa amandla abo ebhondi, ukugcinwa kwamanzi kanye nezakhiwo ze-rheological. Ifinyelela lezi zinzuzo ngokusebenza njenge-thickener, i-rheology modifier kanye ne-ejenti yokugcina amanzi. Ngokulawula izakhiwo ze-rheological zengxube, i-MHEC ingasetshenziswa ukufeza ukuvumelana okufunayo, ukugeleza nokubeka izakhiwo zengxube.
Enye yezinzuzo eziphawuleka kakhulu zokusebenzisa i-MHEC odakeni lwengxube eyomile yikhwalithi engaguquki yengxube engafinyelelwa. Ngosizo lwe-MHEC, abakhiqizi be-dry-mix mortar bangakwazi ukulawula kangcono i-viscosity, ukugeleza nokubeka izici zengxube, ngaleyo ndlela baqinisekise ikhwalithi yomkhiqizo engaguquki nokusebenza. Lokhu akukhulisi nje kuphela ukuqina nokuphila isikhathi eside kwesakhiwo, futhi konga izindleko ngokunciphisa udoti wezinto ezibonakalayo nokusebenza kabusha.
Ngaphezu kwalokho, i-MHEC isiza ukuthuthukisa ukusebenza kwemikhiqizo yodaka oluxutshwe okomile. Ngokwandisa isikhathi sokusebenza sokuxuba, i-MHEC yenza kube lula ukuphatha, ukusabalalisa nokuqeda ukuxuba kodaka. Le nzuzo ibonakala ikakhulukazi kumaphrojekthi wokwakha amakhulu lapho izingxube ezomile zithuthwa ngamabanga amade futhi ukucutshungulwa kubalulekile ekusebenzeni okungaguquki.
I-MHEC iphinde idlale indima ebalulekile ekwandiseni amandla nokuqina kwemikhiqizo eqediwe. Ngokungeza i-MHEC ekuxubeni, abakhiqizi bangathuthukisa ukunamathela nokuhlanganiswa kwezinsimbi ezomile ezixubene, okuholela ekuboshweni okunamandla endaweni ye-substrate. Lokhu akugcini nje ngokuthuthukisa impilo yodaka, kodwa futhi kuthuthukisa ubuqotho besakhiwo sonke sesakhiwo.
Enye inzuzo yokusebenzisa i-MHEC ku-dry-mix mortars yikhono layo lokwandisa ukugcinwa kwamanzi. Endaweni yokwakha, ukugcinwa kwamanzi kubalulekile ukuze kuqinisekiswe ukuthi udaka lugcina amandla nogqinsi lwalo ngisho nangaphansi kwezimo ezimbi njengomswakama ophezulu noma izinga lokushisa elidlulele. I-MHEC isiza ukugcina umswakama ekuxubeni, ukunciphisa ukushwabana, ukuqhekeka kanye namabhamuza ephini. Lokhu kwenza umkhiqizo wokugcina uqine futhi uqine, ukwazi ukumelana novivinyo lwesikhathi nesimo sezulu.
Ngaphezu kwalezi zinzuzo, i-MHEC iguquguquka kakhulu futhi ingenziwa ngezifiso ukuze ihlangabezane nezidingo ezithile. Isibonelo, ngokushintsha izinga lokushintsha kanye nesisindo samangqamuzana, izakhiwo ze-MHEC zingalungiselelwa izinhlelo zokusebenza ezithile. Ngakho-ke, i-MHEC ingasetshenziswa kabanzi ezimeni ezahlukene zokwakha ezinezidingo ezahlukene, ezifana nokhonkolo oluqinile, ukugqoka okungangeni manzi, ukunamathela kwe-tile, njll.
Ukufingqa, i-MHEC ngokungangabazeki iyisengezo esisebenza kahle kakhulu esiguqule imboni ye-dry-mix mortar. Kwenza ngcono ukungaguquguquki, amandla kanye nokugcinwa kwamanzi emikhiqizweni yodaka lwengxube eyomile, okuyenza ibe isithako esibalulekile kumaphrojekthi wokwakha wesimanje. Ngokuvumela abakhiqizi ukuthi bakhiqize izingxube zodaka ezingaguquki, ezisezingeni eliphakeme, i-MHEC ikhulisa kakhulu ukusebenza kahle nokusimama kwemboni yezokwakha. Akumangalisi-ke ukuthi abaningi embonini babheka i-MHEC njengenguquko yomdlalo embonini yodaka oluxubekile.
