1. Ukwengeza i-methylcellulose kusimende kungaba nomthelela omkhulu ezicini zayo zokusebenza. I-Methylcellulose iphuma ku-cellulose evame ukusetshenziswa njenge-thickener, stabilizer, kanye ne-ejenti yokugcina amanzi ezimbonini ezihlukahlukene, kuhlanganise nezokwakha. Uma yengezwe ezixubeni zikasimende, i-methylcellulose ithinta izici ezimbalwa ezibalulekile zemishini njengamandla, ukusebenza, isikhathi sokusetha nokuqina.
2. Omunye wemisebenzi eyinhloko ye-methylcellulose admixture umphumela wayo ekusebenzeni kwezingxube zikasimende. I-Methylcellulose isebenza njenge-ejenti egcina amanzi, okusho ukuthi isiza ukuvimbela amanzi engxube ukuthi ahwamuke. Lokhu kuthuthukisa ukusebenza kukasimende, okwenza kube lula ukuxutshwa, ukubeka nokuqeda. Ukusebenza okuthuthukisiwe kunenzuzo ikakhulukazi ezinhlelweni zokwakha lapho ukubekwa okufanele nokusikwa kubalulekile ukuze kuzuzwe ubuqotho besakhiwo obufunekayo kanye nobuhle.
3. Ukwengezwa kwe-methylcellulose kuzophinde kuthinte isikhathi sokusetha usimende. Isikhathi sokusetha yisikhathi esithathayo ukuze usimende uqine futhi uthuthukise amandla awo okuqala. I-Methylcellulose inganweba isikhathi sokusetha, ivumele ukuguquguquka okwengeziwe ekusetshenzisweni nasekulungiseni ngesikhathi sokwakha. Lokhu kuwusizo ikakhulukazi lapho kudingeka izikhathi ezinde zokusetha, njengasezindaweni ezinkulu zokwakha noma ezimweni ezishisayo lapho ukumiswa okusheshayo kungase kubangele izinselele.
4. I-Methylcellulose isiza ukuthuthukisa amandla okucindezela usimende. Amandla acindezelayo ayisihluthulelo semishini esikala ikhono lempahla lokumelana nemithwalo ye-axial ngaphandle kokuwa. Ucwaningo luye lwabonisa ukuthi ukwengeza i-methylcellulose kungathuthukisa amandla acindezelayo wezinto zikasimende. Lokhu kuthuthukiswa kubangelwa ukuhlakazeka kwezinhlayiya zikasimende okuthuthukisiwe kanye nama-voids ancishisiwe ngaphakathi kwesakhiwo.
5. Ngaphezu kwamandla okucindezela, ukungezwa kwe-methylcellulose kuzoba nomthelela omuhle emandleni e-flexural kasimende. Amandla e-Flexural abalulekile ezisetshenziswa lapho izinto zingaphansi kokugotshwa noma amandla aqinile. I-Methylcellulose isiza ukufeza ukusabalalisa okufanayo kwezinhlayiya futhi iqinise i-matrix kasimende, ngaleyo ndlela ikhulise amandla okuguquguquka.
6. Ukuqina kwezinto zikasimende kungesinye isici esithintekayo ngokufakwa kwe-methylcellulose. Ukuqina kuhlanganisa ukumelana nezinto ezehlukene zemvelo, njengemijikelezo yokuncibilika kweqhwa, ukuhlasela kwamakhemikhali, nokuguga. I-Methylcellulose ingathuthukisa ukuqina kukasimende ngokuthuthukisa i-microstructure yonke kanye nokunciphisa ukuvuthwa kwempahla, ngaleyo ndlela inciphise ukungena kwezinto eziyingozi.
7. Kubalulekile ukuqaphela ukuthi ukusebenza kahle kwe-methylcellulose njengengxube kasimende kuncike ezicini ezihlukahlukene, okuhlanganisa uhlobo nenani le-methylcellulose, ukwakhiwa kwe-cement ethile, kanye nokusetshenziswa okuhlosiwe. Ngakho-ke, ukucatshangelwa ngokucophelela nokuhlolwa kufanele kwenziwe ukuze kwandiswe umthamo futhi kuqinisekiswe ukuhambisana nezinye izingxenye zengxube kasimende.
Ukwengezwa kwe-methylcellulose kusimende kungaba nemiphumela ehlukahlukene enenzuzo ezindaweni zayo zemishini, okuhlanganisa ukusebenza okuthuthukisiwe, ukukhuphuka kwesikhathi sokusetha, ukuqina okuthuthukisiwe nokuguquguquka, nokuqina okukhulayo. Lezi zithuthukisi zenza i-methylcellulose ingxube ebalulekile embonini yezokwakha, ihlinzeka onjiniyela nabakhi ukuguquguquka okukhulu nokulawula izakhiwo zezinto zikasimende.
