I-MC esetshenziselwa udaka lwempushana eyomile iyadingeka ukuthi ibe yimpushana, enokuqukethwe kwamanzi aphansi, kanti ukucoleka kudinga u-20% ~ 60% wesayizi wezinhlayiyana ukuba ube ngaphansi kuka-63um. Ukucoleka kuthinta ukunyibilika kwe-methyl cellulose ether. I-coarse MC imvamisa isesimweni sama-granules, futhi kulula ukuncibilika emanzini ngaphandle kokuhlanganiswa, kodwa izinga lokuhlakazeka lihamba kancane, ngakho-ke alifanelekile ukusetshenziswa kudaka olomile lwempuphu.
Odakeni lwempushana olomile, i-MC ihlakazwa phakathi kwama-aggregates, izigcwalisi ezinhle nosimende nezinye izinto zikasimende. Impushana enhle ngokwanele kuphela engagwema i-methyl cellulose ether agglomeration lapho ixutshwa namanzi. Lapho i-MC yengezwe ngamanzi ukuze ihlakaze ama-agglomerate, kunzima kakhulu ukuhlakazeka nokuhlakazeka. I-coarse MC ayigcini nje ngokumosha, kodwa futhi inciphisa amandla endawo odaka. Uma i-powder mortar enjalo eyomile isetshenziswa endaweni enkulu, ijubane lokuphulukisa le-powder eyomile yendawo lizoncishiswa kakhulu, futhi imifantu izovela ngenxa yezikhathi ezahlukene zokuphulukisa. Ngodaka olufuthwe ngomshini ngokwakhiwa kwemishini, ngenxa yesikhathi esifushane sokuxuba, imfuneko yokucwenga iphakeme.
Ukucoleka kwe-MC kuphinde kuthinte ukugcinwa kwayo kwamanzi. Ngokuvamile, kuma-methyl cellulose ether ane-viscosity efanayo kodwa ukucoleka okuhlukile, ngaphansi kwesamba esifanayo sokwengezwa, ukucoleka kuya kuba ngcono umphumela wokugcina amanzi.
Ukugcinwa kwamanzi kwe-MC nakho kuhlobene nezinga lokushisa elisetshenzisiwe, futhi ukugcinwa kwamanzi kwe-methyl cellulose ether kuncipha ngokunyuka kwezinga lokushisa. Kusetshenziswa kuma-substrates ashisayo ngaphansi kwezimo zokushisa okuphezulu ukuze kusheshiswe ukuphulukiswa kukasimende kanye nokuqina kodaka olomile lwempuphu. Ukwehla kwezinga lokugcinwa kwamanzi kuholela ethonyeni lokusebenza kanye nokumelana nokuqhekeka, futhi kubaluleka ukunciphisa umthelela wesici sokushisa ngaphansi kwalesi simo.
Nakuba izithasiselo ze-methyl hydroxyethyl cellulose ether njengamanje zibhekwa njengezihamba phambili ekuthuthukisweni kwezobuchwepheshe, ukuncika kwazo ekushiseni kusazoholela ekwenzeni buthaka ukusebenza kwe-powder mortar. Ngokuphathwa okuthile okukhethekile ku-MC, njengokwandisa izinga le-etherification, njll., umphumela wokugcina amanzi ungagcinwa ezingeni lokushisa eliphezulu, ukuze ukwazi ukunikeza ukusebenza okungcono ngaphansi kwezimo ezinzima.
