I-Cellulose ether, ikakhulukazi i-Hydroxypropyl Methylcellulose (HPMC), iyisengezo esisetshenziswa kakhulu ekwenzeni amatshe nodaka lokuplasta.Izakhiwo zayo eziyingqayizivele ziyenza ibe isithako esibalulekile embonini yezokwakha.Kulesi sihloko, sizohlola indima ye-cellulose ether ekuthuthukiseni ukusebenza nokusebenza kodaka.
Umsebenzi oyinhloko we-cellulose ether ku-masonry kanye nodaka lokuplasta ukuthuthukisa ukusebenza.I-HPMC isebenza njenge-ejenti egcina amanzi, iqinisekisa ukuthi udaka lugcina ukufana kwalo phakathi nokufakwa.Ngaphandle kwe-cellulose ether, ingxube iyoma ngokushesha, okwenza kube inselele ngezisebenzi ukuba zisakaze futhi zigcobe udaka ngokulinganayo.I-HPMC isiza ukunweba isikhathi sokusebenza sodaka, okuvumela ukubambelela okungcono nokunciphisa isidingo sokuxutshwa kabusha njalo.
Enye indima ebalulekile ye-cellulose ether odakeni amandla ayo okuthuthukisa amandla ebhondi.Uma yengezwe kumxube, i-HPMC idala ifilimu elincanyana elizungeze izinhlayiya zikasimende, okuthuthukisa ukunamathela phakathi kodaka ne-substrate.Le filimu iphinde isebenze njenge-lubricant, inciphisa ukungqubuzana phakathi kwezinhlayiya, futhi ivimbele ukuhlukaniswa ngesikhathi sokuhamba nokusetshenziswa.Amandla ebhondi athuthukisiwe ahlinzekwa i-cellulose ether aqinisekisa umkhiqizo oqediwe ohlala isikhathi eside futhi oqinile.
I-Cellulose ether iphinde ibe nomthelela ekuphikisweni okuphelele kwamanzi kwe-masonry ne-plastering mortar.Ukuba khona kwe-HPMC kusiza ukwakha ifilimu ye-hydrophobic ebusweni bodaka, ukuvimbela ukungena kwamanzi kanye nokulimala okulandelayo.Lokhu kumelana namanzi kubaluleke kakhulu ezindaweni zangaphandle lapho udaka luchayeka ngaphansi kwezimo zezulu ezinzima.Ngokunciphisa ukumuncwa kwamanzi, i-cellulose ether isiza ukuvimbela imifantu, i-efflorescence, nezinye izinkinga ezihlobene nomswakama, okuholela ekuphileni isikhathi eside kokwakhiwa.
I-Cellulose ether idlala indima ebalulekile ekulawuleni ukuncipha kanye nokuqhekeka kodaka.Ukwengezwa kwe-HPMC kusiza ukunciphisa ukuncipha kokuqina kodaka, okuyimbangela evamile yokuqhekeka.Ngokunciphisa ukuncipha, i-cellulose ether iqinisekisa ukuthi umkhiqizo ophelile uhlala uphilile ngokwesakhiwo.Ngaphezu kwalokho, ukumelana nokuqhekeka okuhlinzekwa yi-HPMC kukhuthaza ukuqina okungcono nobuhle, kugweme isidingo sokulungisa okubizayo noma ukusetshenzwa kabusha ngokuhamba kwesikhathi.
Sengiphetha, i-cellulose ether, ikakhulukazi i-Hydroxypropyl Methylcellulose (HPMC), idlala indima ebalulekile ekwenzeni amatshe kanye nodaka lokuplasta.Ikhono layo lokuthuthukisa ukusebenza, ukuqinisa amandla ebhondi, ukuhlinzeka ukumelana namanzi, nokuncipha kokulawula kuyenza ibe isengezo esibalulekile embonini yezokwakha.Ngezinzuzo zayo eziningi, i-cellulose ether iqinisekisa ukuthi udaka kulula ukusebenza ngalo, luhlala isikhathi eside, futhi luhlala isikhathi eside.Abakhi nosonkontileka bangathembela ku-cellulose ether ukuze balethe ukusebenza okuphakeme futhi bathole imiphumela yekhwalithi ephezulu kumaphrojekthi wabo wokwakha namaphrojekthi wokuplasta.
