Ma cellulose ethers ndi ma polima osunthika komanso osunthika omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza kupanga zisa za ceramic ndi zinthu zina.
1. Chiyambi cha cellulose ether:
Ma cellulose ethers amachokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cellulose.Amapezeka ndi kusintha kwa mankhwala a cellulose, zomwe zimapangitsa ma polima osungunuka m'madzi kapena omwazika madzi.Magwero ambiri a cellulose amaphatikizapo zamkati zamatabwa, thonje, ndi zida zina zamamera.
2. Mitundu ya ma cellulose ethers:
Pali mitundu yambiri ya ma cellulose ethers, iliyonse ili ndi zinthu zapadera zomwe zimayenera kugwiritsidwa ntchito mwapadera.Mitundu ina yodziwika bwino ndi monga methylcellulose (MC), ethylcellulose (EC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), ndi carboxymethylcellulose (CMC).Kusankhidwa kwa cellulose ether kumadalira zinthu zomwe zimafunidwa pomaliza.
3. Njira yopanga:
Kupanga ma cellulose ethers kumaphatikizapo njira zingapo, kuphatikizapo kuchotsa cellulose, kusintha mankhwala, ndi kuyeretsa.Ma cellulose amayamba kuchotsedwa muzomera ndiyeno zochita za mankhwala zimagwiritsidwa ntchito poyambitsa magulu ogwira ntchito monga methyl, ethyl, hydroxyethyl kapena carboxymethyl.Zotsatira za cellulose ether zimayeretsedwa kuti zichotse zonyansa ndikukwaniritsa zomwe mukufuna.
4. Makhalidwe a cellulose ether:
Ma cellulose ethers ali ndi zinthu zosiyanasiyana zofunika, zomwe zimawapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana.Zinthuzi zimaphatikizapo kusungunuka kwamadzi, luso lopanga filimu, kukhuthala, komanso kukhazikika pa kutentha kwakukulu ndi pH.Zinthu izi zimathandizira kusinthasintha kwa ma cellulose ethers m'mafakitale osiyanasiyana.
5. Kugwiritsa ntchito cellulose ether:
Ma cellulose ethers amagwiritsidwa ntchito m'mafakitale ambiri, kuphatikiza mankhwala, chakudya, zomangamanga, nsalu ndi zoumba.Ntchito zake zimachokera ku kugwiritsidwa ntchito ngati chowonjezera muzakudya mpaka kukulitsa zida zomangira.Pankhani ya zoumba, ma cellulose ether amagwira ntchito yofunika kwambiri popanga zisa.
6. Selulosi etha mu zisa zadothi:
Zisa zisa za ceramic ndi zida zomangika zomwe zimakhala ndi ma cell omwe amapangidwa motsatizana ndi hexagonal kapena zisa.Ma Ceramics awa amadziwika chifukwa cha malo awo okwera kwambiri, kuwonjezereka kwamafuta ochepa, komanso kutentha kwambiri komanso kusamutsa katundu wambiri.Ma cellulose ethers amagwiritsidwa ntchito popanga zisa za ceramic pazifukwa izi:
Binders ndi Rheology Modifiers: Ma cellulose ethers amakhala ngati omangira, akugwira tinthu tating'onoting'ono ta ceramic panthawi yakuumba.Kuphatikiza apo, imagwira ntchito ngati rheology modifier, yomwe imakhudza kuyenda ndi kusinthika kwa ma ceramic slurries.
Maonekedwe a thupi lobiriwira: Miyala ya ceramic yokhala ndi ma cellulose ethers amagwiritsidwa ntchito kupanga matupi obiriwira a zisa za zisa.Matupi obiriwira ndi nyumba za ceramic zomwe sizimawotchedwa zomwe zimawumbidwa ndikuwumitsidwa musanapitilize kukonzanso.
Kuphatikiza ndi kuyanika: Ma cellulose ether amathandiza tinthu tating'onoting'ono ting'onoting'ono ting'onoting'ono poyanika.Zimalepheretsa kusweka ndi kusinthika, kuonetsetsa kuti thupi lobiriwira limasunga umphumphu wake.
Kupsa ndi kutentha: M'magawo otsatirawa a kupanga zisa za zisa, ma cellulose ether amayaka, ndikusiya zing'onozing'ono zomwe zimathandiza kupanga zisa.Njira yopangira sintering kenako imapitilira kupeza chomaliza cha ceramic.
7. Ntchito zina zama cellulose ethers:
Kuphatikiza pa zoumba za zisa, ma cellulose ethers amagwiritsidwa ntchito pazinthu zina zosiyanasiyana komanso m'mafakitale:
Mankhwala: Amagwiritsidwa ntchito ngati chomangira komanso chophatikizira pakupanga mapiritsi.
Makampani azakudya: Ma cellulose ethers amagwiritsidwa ntchito ngati zolimbitsa thupi, zolimbitsa thupi komanso zopangira ma emulsifiers muzakudya.
Zida Zomangamanga: Zimawonjezera mphamvu zamatope, zomatira ndi zokutira.
Zovala: Ma cellulose ethers amagwiritsidwa ntchito posindikiza nsalu ndi kupanga makulidwe.
8. Mavuto ndi malingaliro:
Ngakhale ma cellulose ether amapereka zabwino zambiri, kugwiritsa ntchito kwawo kumakhalanso ndi zovuta zina.Izi zitha kuphatikizirapo zovuta zomwe zingachitike pazachilengedwe zokhudzana ndi kapangidwe kake komanso kufunikira kopeza zinthu zopangira moyenera.Ntchito yofufuza ndi chitukuko ikupitilira kuthana ndi zovutazi ndikuwongolera kukhazikika kwazinthu zonse za cellulose ether.
9. Zomwe zidzachitike m'tsogolo:
Pamene teknoloji ikupita patsogolo ndi kukhazikika kumakhala nkhani yofunika kwambiri, tsogolo la cellulose ethers lingaphatikizepo luso lazopangapanga, kuwonjezereka kwa kugwiritsidwa ntchito kwa zopangira zamoyo, ndi chitukuko cha ntchito zatsopano.Kusinthasintha kwa ma cellulose ethers kumapangitsa kukhala chinthu chodalirika m'mafakitale osiyanasiyana, ndipo kafukufuku wopitilira akhoza kuwulula zotheka zatsopano.
10. Mapeto:
Ma cellulose ethers ndi ma polima osunthika omwe amagwiritsidwa ntchito zambiri m'mafakitale angapo.Kugwiritsiridwa ntchito kwake muzoumba zama cell kumawunikira kufunikira kwake popanga zida zapamwamba zokhala ndi zinthu zapadera.Pamene mafakitale akupitiriza kufunafuna zipangizo zokhazikika komanso zogwira ntchito, ma cellulose ethers akuyembekezeka kugwira ntchito yofunika kwambiri pokwaniritsa zosowazi.Kafukufuku ndi chitukuko chomwe chikupitilira chidzakulitsa ntchito zama cellulose ether ndikukulitsa kukhazikika kwawo konse.
