Njengoba isidingo sezinto zokwakha sikhula, nesidingo sezithasiselo ezithuthukisa ukusebenza nokuqina. I-high viscosity methylcellulose (HPMC) ingenye yezithasiselo ezinjalo futhi isetshenziswa kabanzi ekusetshenzisweni kodaka olomile. I-HPMC iyinhlanganisela yezinto eziphilayo eguquguqukayo enezakhiwo ezinhle kakhulu zokubopha nokuqina, okwenza ibe yindawo ekahle kumaphrojekthi okwakha.
Udaka olomile luyinto ethandwayo esetshenziselwa ukwenza izitini, amabhlogo nezinye izakhiwo zokwakha. Lwenziwa ngokuxuba amanzi, usimende nesihlabathi (futhi ngezinye izikhathi ezinye izithasiselo) ukuze kwakheke unamathisela obushelelezi nongaguquguquki. Kuye ngokusetshenziswa nendawo, udaka lomile ngezigaba ezahlukene, futhi isigaba ngasinye sidinga izakhiwo ezahlukene. I-HPMC inganikeza lezi zakhiwo kuzo zonke izigaba, okwenza kube yinto enhle kakhulu kudaka olomile.
Phakathi nezigaba zokuqala zokuxuba, i-HPMC isebenza njengesihlanganisi, isiza ekubambeni ingxube ndawonye. Ukuqina okuphezulu kwe-HPMC kuqinisekisa futhi ingxube ebushelelezi nehambisanayo, kuthuthukisa ukucutshungulwa kwayo futhi kunciphisa ingozi yokuqhekeka. Njengoba ingxube yoma futhi iqina, i-HPMC yakha ifilimu evikelayo esiza ekuvimbeleni ukushwabana nokuqhekeka okungenza isakhiwo sibe buthaka.
Ngaphezu kwezakhiwo zayo zokunamathela kanye nokuvikela, i-HPMC inekhono elihle kakhulu lokugcina amanzi kanye nokuhlakazeka. Lokhu kusho ukuthi udoti uhlala usetshenziswa isikhathi eside, okuvumela isikhathi esengeziwe sokulungisa nokuthuthukisa umkhiqizo oqediwe. Ukugcinwa kwamanzi kuqinisekisa nokuthi udoti awomi ngokushesha kakhulu, okungabangela ukuqhekeka futhi kunciphise ikhwalithi iyonke yephrojekthi.
Okokugcina, i-HPMC iphinde ibe yinto yokujiyisa enhle kakhulu ethuthukisa ikhwalithi iyonke yengxube. Izakhiwo zokujiyisa ze-HPMC zisiza ekunciphiseni ukujiya noma ukujiya, okungenzeka uma ingxube ingajiyi ngokwanele. Lokhu kusho ukuthi umkhiqizo oqediwe uzoba ohambisanayo futhi osezingeni eliphezulu, okuqinisekisa ukuthi uhlangabezana nezidingo zokusebenza zephrojekthi.
Sekukonke, i-methylcellulose ene-viscosity ephezulu iyisengezo esibalulekile ekusetshenzisweni kwe-dry mortar. Izakhiwo zayo zokubopha, ukuvikela, ukugcina amanzi kanye nokuqina ziqinisekisa ukuthi i-dry mortar isezingeni eliphezulu, okubalulekile ekuqineni nasekusebenzeni kwamaphrojekthi okwakha. Ukusebenzisa i-HPMC ekusetshenzisweni kwe-dry mortar kungandisa nokuphila kwesakhiwo, kunciphise izindleko zokulungisa, futhi kuthuthukise ukuphepha kwesakhiwo.
Ngamafuphi, isidingo sezinto zokwakha ezisebenza kahle siyakhula futhi ukusetshenziswa kwe-methylcellulose (HPMC) ene-viscosity ephezulu ekusetshenzisweni kodaka olomile kuyanda. I-HPMC inezindawo ezinhle kakhulu zokunamathela, ukuvikela, ukugcina amanzi kanye nokuqina, okwenza ibe yisithasiselo esibalulekile kumaphrojekthi okwakha. Ukusebenzisa i-HPMC ekusetshenzisweni kodaka olomile akugcini nje ngokuthuthukisa ukusebenza nokuqina kwesakhiwo, kodwa futhi kuthuthukisa impilo yaso yesevisi kanye nekhwalithi iyonke.
