Pamwamba pa ceramization - kupopera mbewu mankhwalawa ndi plasma ndikudzifalitsa pawokha kutentha kwakukulu
Kupopera kwa plasma kumapanga DC arc pakati pa cathode ndi anode. Arc imapangitsa mpweya wogwira ntchito kukhala plasma yotentha kwambiri. Lawi la plasma limapangidwa kuti lisungunuke ufawo kupanga madontho. Mtsinje wothamanga kwambiri wa gasi umapangitsa kuti madonthowo akhale atomize ndipo kenako amawatulutsa ku gawo lapansi. Pamwambapo amapanga zokutira. Ubwino wa kupopera mbewu mankhwalawa ndi plasma kutentha ndi okwera kwambiri, kutentha pakati akhoza kufika pamwamba pa 10 000 K, ndipo aliyense mkulu kusungunuka mfundo ceramic ❖ kuyanika akhoza kukonzekera, ndi ❖ kuyanika ali kachulukidwe wabwino ndi mkulu kugwirizana mphamvu. Choyipa chake ndikuti kupopera mbewu mankhwalawa moyenera ndikwambiri. Zida zotsika, komanso zokwera mtengo, ndalama zogulira kamodzi ndizokwera.
Self-propagating high-temperature synthesis (SHS) ndi ukadaulo wopangira zida zatsopano podziyendetsa pawokha kutentha kwamphamvu kwamankhwala pakati pa ma reactants. Zili ndi ubwino wa zipangizo zosavuta, njira yosavuta, yopangira zinthu zambiri, kugwiritsa ntchito mphamvu zochepa komanso kusaipitsa. Ndiukadaulo wapamwamba waukadaulo womwe uli woyenera kwambiri kuteteza khoma lamkati la mipope. Chingwe cha ceramic chokonzedwa ndi SHS chimakhala ndi mphamvu zomangirira kwambiri, kuuma kwakukulu komanso kukana dzimbiri, zomwe zimatha kukulitsa moyo wapaipi. Chigawo chachikulu cha liner ya ceramic yomwe imagwiritsidwa ntchito pamapaipi a petroleum ndi Fe + Al2O3. Njirayi ndi kusakaniza mofanana chitsulo okusayidi ufa ndi aluminiyamu ufa mu chitoliro zitsulo, ndiyeno atembenuza pa liwiro lalikulu pa centrifuge, ndiye kuyatsa ndi spark magetsi, ndi ufa ukuyaka. Kusamukako kumachitika kuti apange wosanjikiza wosungunuka wa Fe + Al2O3. Chosanjikiza chosungunuka chimayikidwa pansi pa mphamvu ya centrifugal. Fe ili pafupi ndi khoma lamkati la chitoliro chachitsulo, ndipo Al2O3 imapanga chingwe chamkati cha ceramic kutali ndi khoma la chitoliro.
