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, kukhuthala konyowa, nthawi yogwirira ntchito komanso njira yomanga yamatope.Ntchitozi makamaka zimakwaniritsidwa ndi mgwirizano wa haidrojeni pakati pa cellulose etha molekyulu ndi molekyulu yamadzi ndi mafunde a cellulose ether molekyulu, kwenikweni, zimatengera gawo la chomangira cha haidrojeni mu unyolo wa cellulose ether cell ndikufooketsa kuphatikizika kwa cellulose ether, zomwe zimafooketsa kasungidwe ka madzi komanso kunyowetsa mphamvu ya cellulose ether.Opanga matope ambiri samamva mfundo imeneyi, Komano, zoweta matope mankhwala akadali ndi akhakula, sanayambebe kusamala kulabadira siteji ya ntchito ntchito, Komano, timasankha mamasukidwe akayendedwe ndi apamwamba kwambiri. kuposa luso lofunika mamasukidwe akayendedwe, gawo ilinso chipukuta misozi kutayika kwa madzi posungira, koma wettability 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 aatali a cellulose ether cross-link ndikukhala ngati ukonde, zomwe zimakhudza liwiro la mapangidwe a filimu ya cellulose ether komanso mawonekedwe a filimuyo, motero zimakhudza gawo la cellulose ether mumatope, mwachindunji- kuyang'ana chikoka 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 zomatira za matailosi a ceramic, zinthu zomwe zimawonjezeredwa ndi tackifier popanga zimakhala ndi mphamvu zomatira zolimba kwambiri. .
2. Pankhani ya kukana madzi, mphamvu zomatira zomatira zomatira za matailosi a ceramic okhala ndi cellulose ether wowonjezera tackifier popanga ndizoyipa kwambiri kuposa zomwe zimapangidwa popanda tackifier munjira yabwinobwino yopanga, cellulose ether yokhala ndi tackifier imakhudza madzi. kukana 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, ntchito yolumikizirana yomwe imapangitsa kuti cellulose ether amadzimadzi amadzimadzi azikhala ndi chotchinga chapamwamba kwambiri, chomwe chikuwoneka kuti ndichokwera pamayeso, koma kukhalapo kwa tackifier kumakhudza zinthu zambiri zofunika za cellulose. ether, monga kukana madzi, nthawi yotsegula, kunyowa ndi zina zotero.M'malo mwake, mamasukidwe akayendedwe ndi chimodzi mwazowonetsa magwiridwe antchito a cellulose ether, mamasukidwe akayendedwe sicholozera chofunikira pakuchita bwino kwa mapadi a cellulose, koma mtundu ndi zomwe zili m'magulu ziyenera kukhala zomwe opanga matope amayang'ana.
5.Zilinso chifukwa opanga matope amalabadira kwambiri kukhuthala, zomwe zimapangitsa mabizinesi ena kupanga ma cellulose ether kuti awonjezere kukhuthala kudzera muzinthu zowonjezera kuti akwaniritse zofunikira za opanga matope, ndipo mtundu uwu wazinthu umangokhala ndi kukhuthala kowoneka bwino, kokwanira. magwiridwe antchito ndi oyenera chidwi cha ogwiritsa ntchito, ndipo mawonekedwe owoneka bwino amawonekedwe opangidwa ndi kukhuthala kowonjezereka sikungakwaniritse chiphunzitso cha "High viscosity low content" chomwe 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.
