Waa maxay sifooyinka waxqabadka ee ceramics alumina?

Alumina ceramicswaa nooc ka mid ah Al2O3 oo ah alaabta ceeriin ee ugu weyn, corundum (α-al2o3) oo ah wejiga ugu weyn ee crystalline ee walxaha dhoobada ah, wakhtigan xaadirka ah aduunka oo dhan oo aad u badan oo ah alaabta dhoobada oksaydhka. Iyo sababtaalumina dhoobadawaa shay dhoobo sax ah oo aad u xidhan u adkaysta, waxa si balaadhan looga isticmaalaa dhammaan qaybaha nolosha.

Alumina ceramicswaxay leeyihiin sifooyinka soo socda:

1. Xiro iska caabin

daahirnimo sarealuminium ceramicsleeyihiin iska caabin aad u wanaagsan oo xirashada, taas oo ku habboon qaybaha loo isticmaalo waqti dheer.

2, aan qalloocin

daahirnimo sarealuminium ceramicswaa maaddooyin aad u fiican oo loogu talagalay qaybaha saxda ah sababtoo ah waxay leeyihiin xoog foorarsi iyo xoog cadaadis ah mana fududa in la dhaawaco.

3, fududahay in la nadiifiyo

Dusha sare eealuminium ceramicswaa siman yahay, ma fududa in lagu dhejiyo wasakhda, wayna fududahay in la nadiifiyo. Sidaa darteed, waxay ku habboon tahay dib-u-isticmaalka iyo baahida loo qabo ilaalinta nadaafadda goobta caafimaadka.

4, caabbinta kiimikada

Alumina ceramicswaxay leeyihiin caabbinta aashitada iyo alkali adag ee daxalka kiimikada, mana jirto baahi loo qabo in laga walwalo falcelinta kiimikada daawooyinka kale inta lagu jiro isticmaalka.

5, dahaarka wanaagsan

Nadiifinta sare ee alumina ceramic waa qalab aad u wanaagsan oo nadiif ah oo ay ugu wacan tahay wasakhda hoose, waxay awood u leedahay in ay u adkeysato danab ahaan sida walaxda, waxtarka mugga hooseeya, xitaa heerkulka sare si loo ilaaliyo xakamaynta, iyo caabbinta kulaylka aad u fiican.

6, caabbinta balaasmaha

Sababtoo ah nadiifnimada sare ee ceramics alumina (Al 2 O 3> 99.9%) oo aan lahayn ku dhawaad ​​kala soocida intergranular iyo, sidaas darteed, waxaa loo isticmaalaa sida walxaha ka hortagga balasmaha.

Marka la soo koobo, waxaa jira qaar ka mid ah sifooyinka waxqabadka ee ceramics alumina. Alumina ceramics waxay ku leeyihiin meel sare oo ka mid ah alaabta dhoobada ah, waxaana si weyn loogu isticmaalaa qalabka elektiroonigga ah, qalabka korontada, mishiinada, dunta, hawada hawada iyo meelo kale.
