(WintrustekUkuvelisa zombiniI-aluminakwayeMullite)

I-Alomina Ceramic, ngamanye amaxesha kubhekiswa kwiI-Aluminium Oxide (Al23) or i-alumina, yindawo ye-oxide ye-oxide ye-oxide enobunkunkqele kakhulu kwaye iqinile kakhulu. Ngenxa yeempawu zabo,I-Aluminii Ceramicsziphakathi kweyona ceramics edumileyo yokuthambisa, inxibe, kunye noseto lolwakhiwo. Ihlala ivela eBauxite, i-ceramics ye-Aluminii inokubunjwa kukupheliswa, inaliti yokubumba, ukucinezelwa, ukucinezela i-isostatic, ukuphosa amacwecwe, kunye nokuphosa i-slip, kunye nedayimane.

Mulliteiveliswa ngokufanisa i-silica kunye ne-alumina kwindibaniselwano eyahlukileyo ngexesha lenkqubo yokutya, ukudala izinto ezahlukeneyo. Ngenxa yezinyibilikisi, kuthiwa ngu-mullite; Amabanga aphambili, oko kubizwa ngokuba yimorous mullite okanye icumba.

Zimbini iintlobo ze-Synthetic Maillite (Al2o3-Sio2) iimveliso: iifom zepiroung kunye nentshukumo. Amandla aphezulu kunye nokungaxhathisi okhethekileyo kwi-Furw Shock zidityaniswe kwi-mullite e-mullite. Ukwanda kwe-porous therm therm kunye namandla aphezulu ngokuthelekisayo kubonelela ngamanqanaba aphuculweyo wothuso lwe-thermal.

Mullite ceramicsbaqeshiwe kwi-insullical interfayili, iziko, izitshisi, kunye nezicelo zokungaziphathi kakuhle ngenxa yokothusa okuphezulu kunye nokusebenza kwamaqondo obushushu aphezulu ukuya kuthi ga kwi-2910f (1600 ° C).

Ipropathi ephambili yeI-alumina:

• Uzinzo lobushushu

• Amandla aphezulu kunye nobunzima

• Ukufakelwa kombane

• Ukuxhathisa ngokugcobayo ukunxiba kunye nokuxabana

• Ukukwazi ukumelana nokungabikho kwamaqondo obushushu aphakamileyo

Ipropathi ephambili yeMullite:

• Uzinzo kumaqondo obushushu aphezulu

• Ukuxhathisa kwiikhemikhali

• Ukwandiswa okuncinci kobushushu

• Amandla omatshini

• Ukufakelwa kweenkqubo zombane

Ulwakhiwo kunye nokuqulunqwa

I-Aluminium Oxide (Al23)Amanqanaba acocekileyo asusela kwi-75% ukuya ngaphezulu kwe-99% yeyona nto iphambili kwisithako esisetyenziselwa ukwenza i-Alomina Ceramics. Ubunzima kwaye banxibe ukunyuka kokunyuka kwe-Aluminii Uniction. Isakhiwo se-crystalline sibonelela ngokutya kunye namandla omatshini.

Umxholo owenzayomullite ceramicsNgaba i-aluminium Silicate (3alo3·2SiO2). Zihlala zidalwa ngokuhla kweqondo lobushushu eliphezulu le-silica kunye ne-alumina, evelisa isakhiwo esilula sokuzinza okuphakathi. Ukomelela kuka-Mullite kwi-Shock Shock kunye nokwandiswa komgangatho omncinci kwenza ukuba kubaluleke kakhulu.

Iipropathi zomzimba

I-aluminaUkuxhaphaza okuphezulu kwe-abrasion kwenza ukuba igqibelele kwizixhobo zokusika kunye neengubo ezikhuselayo.

MulliteIimpawu ezizodwa kunye namandla (7-7 mohs ubunzima) zenza ukhetho olufanelekileyo kubuchwephesha beenqwelomoya kunye ne-linestory.

Iipropathi zoomatshini

I-aluminaWaziwa kakhulu ngenxa yobunzima obumangalisayo obumangalisayo, amandla aphezulu ecinezelayo, kunye nokunxiba okuphezulu. Ezi mpawu zikwenza ukuba ukhetho olufanelekileyo lokunxiba ii-liners, ukugaya imithombo yeendaba, kunye nezicelo eziphezulu apho i-abrasion yeyona nto iphambili.

MulliteIngaphantsi kune-Aluminii, ukanti ibonelela ngamandla afanelekileyo ngomatshini ngelixa iphantsi nobunzima. Iimpawu zayo zoomatshini zilungelelana ngokuxhathisa amandla amakhulu amaqondo obushushu.

Ukuxhathisa i-themikhali kunye nemichiza

I-Aluminii Ceramicsinokumelana neqondo lobushushu eliphezulu kakhulu ngelixa usalela ngokwaselwe ngolwakhiwo. Baye baxhathisa kakhulu kwii-Asids kunye ne-alkalis, besenza ukuba bagqibelele kwiimeko ezinentiyo.

MulliteI-ceramics imele ukuba ilungelelene kakhulu i-surry ephezulu yokunganyangeki kunye nokuphumelela okuphantsi kwengqondo. Basebenza ngempumelelo kwiziko eliphezulu lamaqondo, amathanga eKiln, kunye nezicelo zokutshaja apho kwenziwe ngebhayisekile ye-thermal kwenzeka rhoqo.

Isicelo:

I-aluminaIimpawu zombane zefayila zenza zilungele izixhobo ze-elektroniki kunye nezixhobo zebhayoloji. Ngenxa yelowo inxibe ngokuchasene ne-geramics ebalaseleyo, i-ceramics ye-Aluminii ihlala isetyenziswa kwiibhola ezigayayo, zinxibe ii-liners, kunye nemibhobho apho ubomi benkonzo kude.

MulliteUzinzo oluneqondo lobushushu oluphezulu lubalulekile kwi-linescyrings kunye nezinto zenqwelomoya.

Ukushwankathela,I-Aluminii Ceramicszizinto ezikhethiweyo kwiimeko ezinobutshaba ezinokunxiba kwaye zinemichiza ngenxa yobunzima obukhulu, benxila, kunye nokulimala kwemichiza.Mullite ceramicsKwelinye icala, banozinzo oluqaqambileyo kunye nokuzinza okuphezulu kunye nokomelela kubushushu obuziimitha ezikhawulezayo, bebenza bafaneleke ngakumbi kwizicelo zeqondo lobushushu obuphezulu.
