Zida za alumina: zinthu zosatha ntchito komanso mankhwala okhazikika

Mu sayansi ya zinthu, nthawi zonse timafunafuna zinthu zatsopano zokhala ndi makhalidwe abwino komanso kukhazikika. Pakati pa izi, alumina ceramics imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana chifukwa cha makhalidwe awo abwino kwambiri akuthupi ndi a mankhwala, komanso kukana kutentha kwambiri komanso kukana dzimbiri. Lero, tiyeni tiwone bwino kukhazikika kwa mankhwala a alumina ceramics.

Choyamba, kukhazikika kwa mankhwala azoumbaumba za aluminaimaonekera makamaka mu kukana kwake ku ma acid ambiri, maziko ndi ma oxidants. Izi zili choncho chifukwa kapangidwe ka alumina ceramics ndi kolimba ndipo mgwirizano pakati pa mamolekyu ndi wolimba, zomwe zimapangitsa kuti ikhale yokhoza kusunga mawonekedwe ake oyambirira komanso makhalidwe ake m'malo ovuta kwambiri. Kukhazikika kumeneku kumapangitsa alumina ceramics kugwiritsidwa ntchito kwambiri m'mafakitale a mankhwala, mafuta, zitsulo ndi mafakitale ena.

Kachiwiri, kukhazikika kwa mankhwala a alumina ceramics kumaonekeranso mu mphamvu zake zotsutsana ndi ma antioxidants. Pa kutentha kwambiri, zinthu zambiri zimayankha ndi mpweya, zomwe zimapangitsa kuti kapangidwe kake ndi mawonekedwe ake zisinthe. Komabe, alumina ceramics imakhalabe yokhazikika m'malo awa ndipo sichitanso ndi mpweya. Kukana kwa okosijeni kumeneku kumapangitsa alumina ceramics kukhala ndi gawo lofunika kwambiri mumlengalenga, usilikali ndi madera ena.

Kuphatikiza apo, kukhazikika kwa mankhwala a alumina ceramics kumaonekeranso mu kukana kwake dzimbiri ndi asidi. M'moyo wathu watsiku ndi tsiku, ma acid ndi maziko ndi zinthu zofala, ndipo zimakhala ndi zotsatirapo zowononga pa zinthu zambiri. Komabe, ma alumina ceramics amatha kukana dzimbiri ndi asidi ndikusunga mawonekedwe awo oyambirira. Kukana uku ku asidi ndi madzi a alkali kumapangitsa kuti ma alumina ceramics azigwiritsidwa ntchito kwambiri pokonza chakudya, chemistry, zamankhwala ndi zina.

Kawirikawiri, mphamvu za mankhwala a alumina ceramics ndi zokhazikika, kotero kuti zimatha kugwira ntchito bwino komanso mawonekedwe abwino m'malo osiyanasiyana ovuta. Kukhazikika kumeneku kumapangitsa kuti alumina ceramics igwiritsidwe ntchito kwambiri m'magawo ambiri.
