Indlela iiThayile ze-Alumina zisebenza ngayo iSikhokelo soMgangatho weNgcali yeeCeramics

Iiseramikhi ze-alumina zizixhobo zobugcisa ezisebenza kakhulu ezinokuqina okukhethekileyo kunye nokuguquguquka, ukunika iingcali, abaphandi kunye nabathanda ngokufanayo inkqubo yokuvelisa eqinileyo yemveliso ye-alumina ye-ceramic ephezulu. Esi sikhokelo sihlalutya kuzo zonke izigaba zale nkqubo yokuvelisa ukubanika lonke ulwazi olufunekayo ukwenza i-alumina ceramics yodidi oluphezulu..

Ithayile ye-alumina ye-ceramic ye-ceramic ibonelela ngokhuseleko ekunxibeni okutshabalalisayo kwizixhobo zokuhambisa izixhobo ezisetyenziswa emigodini nasekuqhubeni amalahle., ngoko ke kwandisa ubomi besixhobo ngelixa kucuthwa iindleko zokulondolozwa. I-alumina ecinezelekileyo ye-ISO inxiba iithayile ze-ceramic ezikwaziyo ukudityaniswa zikwabonisa ukumelana nomhlwa kunye nokunyamezela ubushushu obuphezulu..

Ukuqina

Ithayile ye-alumina yenye yezona zinto zinzima kwi-ceramic kwimarike, enikezela ukuxhathisa okungaqhelekanga kunye nokuzinza kwe-thermal. Ngenxa yobunzima bayo obuphezulu kunye namandla, I-alumina yenza ukhetho oluhle kakhulu lokusetyenziswa kwindawo enzima.

Ngokuchaseneyo neentsimbi ezisengozini yokukhukuliseka, I-alumina ceramic inamanqanaba obunzulu obuqinileyo kunye nomphezulu ogudileyo kakhulu onciphisa ukukhuhlana – iimpawu ezivumela ukuba ikwazi ukunyamezela iimeko ezinzima zokucwangcisa kunye nexesha elincitshisiweyo kunye neendleko zokulondoloza.

I-Ceramic lining inokunceda ukukhusela izixhobo ezisetyenziselwa ukuhambisa, ukusetyenzwa kunye nokugcinwa kwezicelo ukusuka ekuwohlokeni ngokuyikhusela kwi-abrasions kunye nokhukuliseko kunye ne-asidi, ityuwa kunye neendawo zealkali; ukongezelela banikezela ngezakhono zokuthintela ukubola kwe-electrochemical.

Ukwandisa ukusebenza kwabo, kubalulekile ukuba ezi mathiriyeli zivela kubavelisi abasele bekhulile nabahlonitshwayo. Oku kuqinisekisa ukuba imathiriyeli ekrwada esetyenziswayo iyahlangabezana nemigangatho yoshishino ngelixa ihlangabezana nazo naziphi na iimfuno ezithile zesicelo.

Ukuxhathisa kwi-abrasion

Nokuba ufuna isicelo sakho – ukusuka kwizinto ezinzima ezixhathisa ukuguga kunye nokugqwala ukuya kwi-insulation yombane – Iiseramikhi ze-alumina zibonelela ngezisombululo ezikumgangatho ophezulu. Yenziwe kusetyenziswa iindlela ezahlukeneyo ezibandakanya ukubumba inaliti, ukucinezela kwe-isostatic kunye nokuphosa ukuphosa; amandla abo adlula uninzi lwesinyithi ngelixa zinika uzinzo lwe-thermal.

I-alumina ye-ceramic imathiriyeli inika ukuchasana okubalaseleyo kwi-sliding kunye ne-abrasion yempembelelo, ukwenza ukuba ibe yimathiriyeli efanelekileyo yokucwangcisa izixhobo ezivezwe kukunxitywa okukhulu. Ngaphaya koko, ubume bayo obungangeni kwiikhemikhali kuthetha ukuba inokunyamezela iiasidi, i-alkalis kunye neetyuwa ngaphandle kwengxaki.

Xa ukhetha umenzi we-alumina ceramic, khangela abo bazimiseleyo. Abavelisi abanjalo kufuneka babonelele ngeesampulu zebhloko kunye neziqwenga ezenzelwe wena ngokukodwa kunye nenkxaso yobuchwephesha eyimfuneko kwiziphumo ezizezona zesicelo kunye noncedo lwemathiriyeli ekrwada..

Ukumelana nokubola

I-alumina ceramics inamandla okumelana nokugqwala kwezinye iindidi ezininzi zezixhobo ngenxa yezinto ezikhuselayo – ukukhusela kwiikhemikhali ezinobungozi kunye neeminerali eziguga ezinye izinto ngokuhamba kwexesha.

I-alumina yinto yokuya kwizinto zokuchasa ukubola kunye nezixhobo ezinganxiliyo kunye neelinen kwiindawo ezithanda ukurhuqeka ngokutyibilika., njengama-chute kunye neehoppers.

Inkqubo ye-Sintering esetyenziselwa ukuvelisa i-alumina ceramics iphucula i-microstructure yabo kunye namandla omatshini, ukudala imathiriyeli yexesha elide efanelekileyo yokusetyenziswa kwamashishini ahlukeneyo.

I-Thermal conductivity

Iiseramikhi zealumina ziqhayisa ngokuxinana okuphezulu, ubulukhuni bedayimani kunye namandla omatshini aphezulu kunye nokumelana nokugqwesa okugqwesileyo kunye neempawu zokuqhuba ubushushu, ukuzenza zibe zizixhobo ezifanelekileyo zokukhusela izixhobo zemizi-mveliso kwiindawo ezifunayo.

Nangona kunjalo, Ulwakhiwo lwazo olu-brittle luthetha ukuba abanaso isakhono sokufunxa amandla othuso njengeentsimbi – oku kunciphisa ukuxhathisa kwabo kwempembelelo kwaye kunokubangela ukuba baphuke okanye baqhekeke ekubetheni okukhawulezileyo okanye okugxile. Iithayile ze-alumina zibonakalisa umphezulu ogudileyo wokugqiba ukunciphisa ukukhuhlana ngezinto ezirhawukayo kunye nokwandisa ubomi bazo, okunciphisa izinga lokunxiba.
