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 amatshe nawokuplasta.
