N’chifukwa chiyani ziwiya za alumina zokhala ndi aluminiyamu yambiri zingagwiritsidwe ntchito popanga zipolopolo?

99% alumina ceramics, yokhala ndi mphamvu zambiri, kuuma kwambiri komanso kusagwira ntchito kwa mankhwala m'malo ambiri, ingagwiritsidwe ntchito bwino pantchito yoteteza zipolopolo. Zipolopolo za zipolopolo ndi mbale za ulusi wolimba komanso wa modulus pamodzi zimapanga gawo loteteza zipolopolo. Chipolopolo cha liwiro lalikulu chikagundana ndi gawo la ceramic, gawo la ceramic limasweka kapena kupanga ming'alu yomwe imafalikira kunja kuchokera pakati, zomwe zimadya mphamvu zambiri za chipolopolocho. Pambuyo pake, mbale ya ulusi wapamwamba imadyanso mphamvu yotsala ya chipolopolocho.

Njira yopezera mphamvuzoumbaumba zosagwira zipolopolopafupifupi akhoza kugawidwa m'magawo atatu:
① Gawo loyamba la kugwedezeka: Chipolopolo chimagunda pamwamba pa ceramic, kupangitsa mutu wa chipolopolo kukhala wofooka ndikusweka zidutswa zazing'ono komanso zolimba pamwamba pa ceramic.
② Gawo la kukokoloka: Chipolopolo chophwanyika chikupitirira kukokoloka malo a chidutswacho, ndikupanga chidutswa chopitirira cha zidutswa za ceramic.
③ Kusintha, kusweka ndi kusweka: Pomaliza, mphamvu yokoka imapangidwa mu ceramic, zomwe zimapangitsa kuti isweke. Panthawi yomwe chipolopolo chikugunda ceramic, chipolopolo ndi ceramic zonse zinawonongeka.

Ubwino umodzi wa zoumba zoteteza zipolopolo kuposa zitsulo ndikuti zitsulo zimasinthasintha pulasitiki ndipo zimayamwa mphamvu zikamalimbana ndi kukhudzidwa ndi mitu ya zipolopolo. Ngati zitavalidwa pa thupi la munthu, kusinthaku kwa pulasitiki kungawononge thupi la munthu. Zoumba zoteteza zipolopolo sizimasintha pulasitiki nthawi zambiri.

Chifukwa chake, kugwiritsa ntchito zida zapamwamba zadothi m'makina oteteza zida ndikokongola kwambiri ndipo kwakhala chida chodzitetezera chomwe chimagwiritsidwa ntchito kwambiri pazida monga ma vesti osawombera zipolopolo, magalimoto, ndi ndege.
