Ma cellulose ethers, makamaka hypromellose ethers, ndi zigawo zofunika za matope a malonda. Kwa cellulose ether, mamasukidwe ake ndi index yofunikira yamabizinesi opangira matope, kukhuthala kwakukulu kwakhala kofunikira kwambiri pamakampani amatope. Chifukwa cha mphamvu yaukadaulo, njira ndi zida, ndizovuta kutsimikizira kukhuthala kwakukulu kwapakhomocellulose ethermankhwala kwa nthawi yaitali. Ma cellulose ether amagwiritsidwa ntchito ngati chosungira madzi, thickener ndi binder muzinthu zamatope, zomwe zimakhudza kwambiri magwiridwe antchito, kukhathamiritsa konyowa, nthawi yogwirira ntchito komanso njira yomanga yamatope. ntchito zimenezi makamaka anakwaniritsa ndi hydrogen chomangira pakati pa mapalo etere molekyulu ndi madzi molekyulu ndi mapindikidwe zochita za mapalo etere molekyulu, kwenikweni, izo zimatenga mbali ya chomangira haidrojeni mu mapadi etero maselo unyolo ndi kufooketsa entanglement wa mapadi efa, amene amafooketsa posungira madzi ndi kunyowetsa mphamvu ya cellulose etha. Opanga matope ambiri samamva mfundo iyi, pa dzanja limodzi, zoweta matope mankhwala akadali ndi akhakula, sanayambebe kusamala kulabadira siteji ya ntchito ntchito, Komano, ife kusankha mamasukidwe akayendedwe ndi apamwamba kwambiri kuposa luso mamasukidwe akayendedwe chofunika, mbali iyi komanso chipukuta misozi imfa ya posungira madzi, koma mu wettability ndi kuonongeka.
Kuchita kwa matope kumakhudzidwa ndi mapadi a cellulose omwe ali ndi zomatira popangira, mu pepalali, kusiyana kwa mphamvu zomatira zomata pakati pa mankhwala a cellulose ndi mankhwala a cellulose ether omwe adawonjezeredwa ndi tackifier mu zomatira matailosi a ceramic zidatsimikiziridwa ndi zoyeserera. Tackifier ndi mtundu wazinthu zomwe zimawonjezeredwa ndi ena opanga ma cellulose ether kuti athandizire kuchepa kwaukadaulo wopanga, ukadaulo ndi zida. Kukhalapo kwa tackifier kumapangitsa kuti ma molekyulu a unyolo atali a cellulose ether cross-link ndi kukhala ngati ukonde, zomwe zimakhudza liwiro la cellulose ether filimu mapangidwe ndi dziko la filimuyo, motero zimakhudza ntchito ya cellulose ether mumatope, chikoka choyang'ana molunjika ndi: mphamvu zomatira zomata zasintha pansi pa chikhalidwe chilichonse chochiritsa; nthawi yoyika matope ikutalika.
1.Pansi pa chikhalidwe chochiritsira, kuwonjezera kwa tackifier ndi cellulose ether popanda tackifier popanga kumapangitsa kuti pakhale mphamvu zomatira zomata za matailosi a ceramic, zinthu zomwe zimaphatikizidwa ndi tackifier popanga zimakhala ndi mphamvu zomatira zolimba kwambiri.
2.Pankhani ya kukana madzi, mphamvu yomatira yolimba ya matailosi a ceramic okhala ndi cellulose ether wowonjezera tackifier munjira yopangira ndi yoyipa kuposa ya chinthucho popanda tackifier munjira yodziwika bwino yopanga, cellulose ether yokhala ndi tackifier imakhudza kukana kwamadzi kwa zomatira matailosi.
3.Kutengera nthawi yoyika mpweya,cellulose etheryokhala ndi tackifier idagwiritsidwa ntchito pomatira matailosi, mphamvu yake yomata yolimba inali yotsika kuposa ya chinthucho popanda tackifier, ndipo nthawi yotsegulira idafupikitsidwa.
4.Ponena za nthawi yoyika, kuthamanga kwa machiritso a cellulose ether ceramic matailosi omatira popanda kuwonjezera tackifier pansi pa ndondomeko yachibadwa yopangira mofulumira. Mwachidule, kukhalapo kwa tackifier, cholumikizira cholumikizira chomwe chimapangitsa kuti cellulose etha amadzimadzi azitha kukhala ndi chopinga chapamwamba kwambiri, chomwe chikuwoneka kuti ndi chapamwamba pakuyesa, koma kukhalapo kwa tackifier kumakhudza zinthu zambiri zofunika kugwiritsa ntchito cellulose ether, monga kukana madzi, nthawi yotsegulira, kunyowa ndi zina zotero. M'malo mwake, mamasukidwe akayendedwe ndi chimodzi mwazowonetsa magwiridwe antchito a cellulose ether, mamasukidwe akayendedwe sicholozera chofunikira cha magwiridwe antchito a cellulose ether, koma mtundu ndi zomwe zili m'magulu ziyenera kukhala cholinga cha opanga matope.
5.Ilinso chifukwa opanga matope kulabadira kwambiri mamasukidwe akayendedwe, zikupangitsa ena mabizinezi kupanga mapadi etere kuonjezera mamasukidwe akayendedwe kudzera zipangizo zina kuti akwaniritse zofunika za opanga matope, ndipo mtundu uwu wa mankhwala okha ndi mkulu kukhuthala zikuoneka, ntchito zake mabuku ndi woyenera chidwi owerenga ', ndi zikuoneka mkulu mamasukidwe akayendedwe kukhuthala otsika "kuchuluka mamasukidwe akayendedwe otsika" kukweza kukhuthala otsika kutheka zomwe opanga matope amayembekezera, koma kulibe kwenikweni. Pofuna kusankha cellulose ether, yomwe ndi yofunika yaiwisi mu matope, mabizinesi matope kutsata apamwamba ndi khola khalidwe ayenera kudziwa zina kumbuyo, izi zidzathandiza kuti opanga kupanga mankhwala mkulu-ntchito, kuonetsetsa kuti mankhwala bata.
