Uma kukhulunywa ngezicelo zodaka, ukuzuza ukusebenza kahle kubalulekile kumaphrojekthi wokwakha ayimpumelelo.Isithako esisodwa esibalulekile esingathuthukisa kakhulu ukusebenza i-MHEC (Methyl Hydroxyethyl Cellulose).Kulesi sihloko, sizocubungula izici ezingokoqobo zokusebenzisa i-MHEC ukwenza kahle izinhlelo zokusebenza zodaka futhi sivule amandla ayo aphelele.
Ukuqonda i-MHEC:
I-MHEC iyisengezo esisekelwe ku-cellulose esisebenza njenge-ejenti egcina amanzi odakeni.Izici zayo eziyingqayizivele ziyenza ikwazi ukuvimbela ukuhwamuka ngaphambi kwesikhathi kanye nokumuncwa komswakama odakeni olumanzi.Ngokugcina amanzi, i-MHEC yandisa inqubo ye-hydration kasimende, yandisa isikhathi sokusebenza sodaka.
Izinzuzo ze-MHEC ku-Mortar Applications:
a.Isikhathi Esandisiwe Somsebenzi: I-MHEC ivumela isikhathi eside sokusebenza, ivumela ukusetshenziswa kodaka olunongqimba oluncane, ukuplasta okushelelayo, nokuqeda isidingo sokumanzisa ngaphambili kwama-substrates amunca.
b.I-Plasticity Ethuthukisiwe: Ukwengezwa kwe-MHEC odakeni kuthuthukisa ipulasitiki yayo, okwenza kube lula ukuxuba, ukusabalalisa, nokuma.Lokhu kuthuthukisa ukusebenza jikelele kanye nolwazi lohlelo lokusebenza.
c.Isikhathi Sokumisa Esilawulwayo: I-MHEC isebenza njenge-retarder, ilungisa isikhathi sokusetha sodaka olusha.Lokhu kulawula kuvumela ukuguquguquka okungcono nokuvumelana nezimo ngesikhathi sokwakha, ukuqinisekisa imiphumela emihle.
Izindlela Zokusebenza Ezisebenzayo:
a.Umthamo Ofanele: Kubalulekile ukunquma umthamo ofanele we-MHEC ngokusekelwe ekusebenzeni okufunayo kanye nezidingo ezithile zephrojekthi.Landela izinkombandlela zomkhiqizi futhi wenze izivivinyo ezincane ukuze ulungise umthamo.
b.Inqubo Yokuxuba: Engeza i-MHEC kumxube wodaka olomile kancane kancane ngenkathi uhlanganisa, uqinisekisa ukuhlakazeka okufanele.Kunconywa ukusebenzisa imishini yokuxuba yekhwalithi ephezulu ukuze kuzuzwe ingxube ye-homogeneous.
c.Ukwengezwa Kwamanzi: Lungisa okuqukethwe kwamanzi ngokwezincomo zomenzi kanye nokuvumelana okufunayo.Izakhiwo ezigcina amanzi ze-MHEC zisiza ukugcina umswakama wodaka, ukunciphisa ingozi yokomisa ngaphambi kwesikhathi.
d.Izindlela Zokufaka Isicelo: Sebenzisa isikhathi esengeziwe somsebenzi esinikezwe i-MHEC ukuze usebenzise ngokucophelela udaka.Bushelelezi futhi ulolonge udaka njengoba kudingeka, uqinisekise ukumbozwa nokunamathela okufanele.
I-MHEC kumaphrojekthi we-Real-Life:
Gqamisa amaphrojekthi aphumelele lapho i-MHEC isetshenziswe khona ukuze kufezwe ukusebenza kahle, ukukhombisa ukusebenza kahle okuthuthukisiwe, ukunciphisa ukusebenza kabusha, kanye nekhwalithi yokwakhiwa ethuthukisiwe iyonke.Xoxa ngezinselele ezithile okubhekane nazo nokuthi i-MHEC isize kanjani ukuzinqoba.
Ukwenza ukwakheka kodaka kudinga ukuqonda okuphelele kwezithako ezisetshenzisiwe.Ngokuhlanganisa i-MHEC ezixubeni zodaka, osonkontileka bangafinyelela ukusebenza kahle, ipulasitiki ethuthukisiwe, nokulawula okungcono isikhathi sokusetha.Njengoba izimfuno zokwakha ziqhubeka nokukhuphuka, ukusebenzisa amandla e-MHEC kuba yisidingo ukuze kube nemiphumela eyimpumelelo yephrojekthi.Yamukela izindawo zokugcina amanzi ze-MHEC, futhi uvule amandla ayo okuyisa izinhlelo zakho zokusebenza zodaka ezingeni elilandelayo lobuhle.
