I-Methyl Hydroxyethyl Cellulose (MHEC) iwugqinsi nokunamathelisa okuvame ukusetshenziswa ezintweni zokwakha. Ukwethulwa kwayo kunomthelela omkhulu ezimpahleni zikasimende matrix.
1. Thuthukisa uketshezi nokusebenza
I-Methyl hydroxyethyl cellulose, njenge-thickener, ingathuthukisa kakhulu uketshezi lwe-matrix kasimende. Kwenza udaka lukasimende luzinze futhi lube noketshezi ngesikhathi sokwakha ngokwandisa i-viscosity yengxube. Lokhu kusiza ukugcwalisa isikhunta esiyinkimbinkimbi futhi kunciphise i-spatter ngesikhathi sokwakhiwa. Ngaphezu kwalokho, i-methyl hydroxyethyl cellulose ingaphinde ithuthukise ukugcinwa kwamanzi kwe-matrix kasimende futhi inciphise isenzakalo sokopha kwe-slurry kasimende, ngaleyo ndlela ithuthukise ikhwalithi yokwakha.
2. Thuthukisa ukunamathela
I-Methyl hydroxyethyl cellulose ingathuthukisa kakhulu izakhiwo zokubopha ze-matrix kasimende. Lokhu kungenxa yokuthi inezinto ezinhle kakhulu zokunamathela futhi ingahlangana nomswakama kusimende ukwenza i-colloid ene-adhesion eqinile. Lo mphumela wokuguqula ubaluleke kakhulu ekuthuthukiseni ukunamathela phakathi kwe-matrix kasimende ne-substrate, ikakhulukazi ekukhoneni odongeni, ukunamathisela kwe-ceramic tile nezinye izinhlelo zokusebenza.
3. Kuthinta amandla nokuqina
Ukwengezwa kwe-methylhydroxyethylcellulose kunomthelela othile emandleni e-matrix kasimende. Ngaphakathi kwebanga elithile lomthamo, i-methylhydroxyethyl cellulose ingathuthukisa amandla okucindezela namandla okuguquguquka kwe-matrix kasimende. Ngokwenza ngcono ukufana nokuzinza kokunamathisela usimende, kunciphisa ama-pores kanye nokuqhekeka ku-matrix ye-cement, ngaleyo ndlela kuthuthukise amandla onke nokuqina kwempahla. Kodwa-ke, uma kungeziwe kakhulu, kungase kubangele ukuncipha kwesibopho phakathi kukasimende nokuhlanganisa ku-matrix kasimende, ngaleyo ndlela kuthinte amandla ayo okugcina.
4. Thuthukisa ukumelana nokuqhekeka kwe-matrix kasimende
Njengoba i-methylhydroxyethylcellulose ingathuthukisa ukugcinwa kwamanzi kwe-matrix kasimende, inganciphisa imifantu ebangelwa ukomiswa ngezinga elithile. Ukomisa ukuncipha kwe-matrix kasimende kungenye yezimbangela eziyinhloko zokuqhekeka, futhi i-methylhydroxyethyl cellulose isiza ukunciphisa ingozi yokuqhekeka okubangelwa ukomisa ukuncipha ngokunciphisa ukuhwamuka kwamanzi ngokushesha.
5. Ukulawulwa kwebhamuza kusimende matrix
I-Methyl hydroxyethyl cellulose ingakha isakhiwo segwebu esizinzile ku-matrix kasimende, esiza ukuthuthukisa ukugoqa komoya kwe-matrix kasimende. Lesi sici sokulawula amabhamuza omoya sidlala indima ekuthuthukiseni izakhiwo zokushisisa okushisayo kwe-matrix kasimende kanye nokunciphisa ukuminyana kwe-matrix kasimende. Nokho, amabhamuza amaningi kakhulu angabangela okokusebenza ukuthi kuphelelwe amandla, ngakho-ke inani elifanele lidinga ukungezwa ngokusekelwe kuhlelo lokusebenza oluthile.
6. Thuthukisa ukungaboli
Ngokwenza ngcono ukugcinwa kwamanzi kwe-matrix kasimende, i-methylhydroxyethylcellulose inganciphisa ngempumelelo ukufinyeleleka kwe-matrix kasimende. Lokhu kubaluleke kakhulu ukuze kuthuthukiswe ukungakwazi ukungena kwamanzi nokusebenza okungangeni kwamanzi kwe-matrix ye-samente, ikakhulukazi ezinhlelweni ezidinga ukuvinjelwa kwamanzi, njengezindlu zangaphansi, izindonga zangaphandle, njll.
Ukusetshenziswa kwe-methylhydroxyethyl cellulose ku-matrix kasimende kungaletha ukuthuthukiswa okuhlukahlukene kokusebenza, okuhlanganisa ukuthuthukiswa kwe-fluidity, ukuthuthukisa ukunamathela, ukuqinisa amandla, ukuthuthukisa ukumelana nokuqhekeka, ukulawula amabhamuza kanye nokwenza ngcono ukungakwazi ukungena emanzini. Kodwa-ke, ukusetshenziswa kwayo nengxenye kudinga ukulungiswa ngokunengqondo ngokuya ngezidingo ezithile zohlelo lokusebenza kanye nezidingo zezinto ezibonakalayo ukuze kutholwe imiphumela yokusebenza engcono kakhulu. Ngokuhlanganisa nokulungiselela okungokwesayensi nokunengqondo, i-methyl hydroxyethyl cellulose ingathuthukisa ngempumelelo ukusebenza kwayo yonke i-matrix kasimende futhi ihlangabezane nezidingo ezahlukene zobunjiniyela.
