Kupaka pamwamba

Kupaka pamwamba pa pulasitiki - kupopera kwa plasma ndi kudzipangira kutentha kwakukulu
Kupopera kwa plasma kumapanga DC arc pakati pa cathode ndi anode. Arc imapangitsa mpweya wogwirira ntchito kukhala plasma yotentha kwambiri. Lawi la plasma limapangidwa kuti lisungunuke ufawo kuti upange madontho. Mpweya wothamanga kwambiri umapangitsa madonthowo kukhala atomu kenako nkuwatulutsa ku substrate. Pamwamba pake pamapanga chophimba. Ubwino wa kupopera kwa plasma ndikuti kutentha kwa kupopera kumakhala kwakukulu kwambiri, kutentha kwapakati kumatha kufika pamwamba pa 10 000 K, ndipo chophimba chilichonse cha ceramic chomwe chimasungunuka kwambiri chikhoza kukonzedwa, ndipo chophimbacho chili ndi kuchuluka kwabwino komanso mphamvu yayikulu yolumikizirana. Choyipa chake ndichakuti mphamvu yopopera ndi yayikulu. Zipangizo zochepa, komanso zodula, komanso ndalama zogulira kamodzi ndizokwera.

Kupanga zinthu zatsopano pogwiritsa ntchito makina oyeretsera kutentha kwambiri (SHS) ndi ukadaulo wopanga zinthu zatsopano mwa kudzipangira kutentha kwamphamvu kwa mankhwala pakati pa zinthu zomwe zimayambitsa kutentha. Uli ndi ubwino wa zida zosavuta, njira yosavuta, kupanga bwino kwambiri, kugwiritsa ntchito mphamvu zochepa komanso kusakhala ndi kuipitsidwa. Ndi ukadaulo waukadaulo wa pamwamba womwe ndi woyenera kwambiri kuteteza khoma lamkati la mapaipi. Chipinda cha ceramic chomwe chimakonzedwa ndi SHS chili ndi mphamvu yolimba kwambiri, kuuma kwambiri komanso kukana dzimbiri, zomwe zimatha kukulitsa moyo wa mapaipi. Gawo lalikulu la chitoliro cha ceramic chomwe chimagwiritsidwa ntchito m'mapaipi amafuta ndi Fe+Al2O3. Njirayi ndikusakaniza ufa wa iron oxide ndi ufa wa aluminiyamu mu chitoliro chachitsulo, kenako nkuzungulira mwachangu pa centrifuge, kenako nkuyaka ndi mphamvu yamagetsi, ndipo ufawo ukuyaka. Kusintha kwa zinthu kumachitika kuti pakhale wosanjikiza wosungunuka wa Fe+Al2O3. Chigawo chosungunukacho chimayikidwa pansi pa mphamvu ya centrifugal. Fe ili pafupi ndi khoma lamkati la chitoliro chachitsulo, ndipo Al2O3 imapanga chitoliro chamkati cha ceramic kutali ndi khoma la chitoliro.
