1. Ukongeza i-methylcellulose kwi-samente ingaba nempembelelo enkulu kwiimpawu zayo zomatshini. I-Methylcellulose yi-cellulose ephuma kwi-cellulose edla ngokusetyenziswa njenge-thickener, stabilizer, kunye ne-arhente yokugcina amanzi kumashishini ahlukeneyo, kuquka ukwakhiwa. Xa ifakwe kwimixube ye-cementitious, i-methylcellulose ichaphazela iipropati ezininzi eziphambili zemishini ezifana namandla, ukusebenza, ixesha lokubeka kunye nokuqina.
2. Omnye wemisebenzi ephambili ye-methylcellulose admixture yimpembelelo yayo ekusebenzeni kwemixube yesamente. I-Methylcellulose isebenza njenge-arhente yokugcina amanzi, oku kuthetha ukuba inceda ukukhusela amanzi kumxube ukuba angabikho. Oku kwandisa ukusebenza kwesamente, okwenza kube lula ukuxuba, ukubeka kunye nokugqiba. Ukuphuculwa kokusebenza kuluncedo ngokukodwa kwizicelo zokwakha apho ukubekwa ngokufanelekileyo kunye nokucheba kubaluleke kakhulu ekuphumezeni imfezeko yolwakhiwo olufunwayo kunye nobuhle.
3. Ukongezwa kwe-methylcellulose kuya kuchaphazela ixesha lokumisela isamente. Ixesha lokumisela lixesha elithathayo ukuze isamente iqine kwaye iphuhlise amandla ayo okuqala. I-Methylcellulose inokwandisa ixesha lokumisela, ivumela ukuguquguquka ngakumbi kwisicelo kunye nokulungiswa ngexesha lokwakha. Oku kuluncedo ngakumbi apho kufuneka amaxesha amisiweyo amade, njengakwiiprojekthi ezinkulu zokwakha okanye kwiimeko ezishushu apho ukucwangciswa ngokukhawuleza kunokubangela iingxaki.
4. I-Methylcellulose inceda ukuphucula amandla oxinzelelo lwesamente. Amandla acinezelayo yipropathi ephambili yomatshini elinganisa ukukwazi kwesixhobo ukumelana nemithwalo ye-axial ngaphandle kokuwa. Uphononongo lubonise ukuba ukongeza i-methylcellulose kunokuphucula amandla oxinzelelo lwezixhobo zesamente. Olu phuculo lubangelwa ukuphuculwa kwe-samente ye-particle dispersion kunye nokunciphisa i-voids ngaphakathi kwesakhiwo.
5. Ukongeza kumandla oxinzelelo, ukongezwa kwe-methylcellulose kuya kuba nefuthe elihle kumandla we-flexural yesamente. Amandla e-Flexural abalulekile kwizicelo apho izixhobo ziphantsi kokugoba okanye ukunyanzeliswa kwamandla. I-Methylcellulose inceda ukufezekisa ukusabalalisa okufanayo kweengqungquthela kunye nokuqinisa i-matrix ye-cementitious, ngaloo ndlela inyusa amandla e-flexural.
6. Ukuqina kwezinto zesamente yenye into echaphazelekayo ngokongezwa kwe-methylcellulose. Ukomelela kubandakanya ukumelana nezinto ezahlukeneyo zokusingqongileyo, ezinje ngemijikelo yokunyibilika komkhenkce, uhlaselo lweekhemikhali, kunye nokunxiba. I-Methylcellulose inokunyusa ukuqina kwe-samente ngokuphucula i-microstructure yonke kunye nokunciphisa ukunyanzeliswa kwezinto eziphathekayo, ngaloo ndlela ukunciphisa ukungena kwezinto ezinobungozi.
7. Kubalulekile ukuba uqaphele ukuba ukusebenza kwe-methylcellulose njenge-sement admixture kuxhomekeke kwizinto ezahlukeneyo, kubandakanywa uhlobo kunye nobungakanani be-methylcellulose, ukuqulunqwa kwe-cement ethile, kunye nesicelo esijoliswe kuyo. Ngoko ke, ukuqwalaselwa ngenyameko kunye novavanyo kufuneka kwenziwe ukwandisa umthamo kunye nokuqinisekisa ukuhambelana namanye amacandelo omxube we-samente.
Ukongezwa kwe-methylcellulose kwi-samente kunokuba nemiphumo eyahlukeneyo enenzuzo kwiimpawu zayo zemishini, kubandakanywa ukuphuculwa kokusebenza, ukunyuswa kwexesha lokumisela, ukunyanzeliswa okuphuculweyo kunye namandla okuguquguquka, kunye nokwandisa ixesha elide. Ezi zongezelelo zenza i-methylcellulose ibe ngumxube oxabisekileyo kushishino lokwakha, ukubonelela iinjineli kunye nabakhi ngokuguquguquka okukhulu kunye nokulawula iipropati zemathiriyeli yesamente.
