Imiyoboro ya Ceramic nibice byihariye

Ibisobanuro bigufi:

Kwambara ceramic idashobora kwihanganira igizwe nibura 90% Al2O3 niyo ikoreshwa cyane kwisi muri iki gihe.

Ibicuruzwa byacu bikozwe mu ifu ya alumina yatoranijwe neza ifite ubunini buke hamwe nubunini bwa CaO. Kwambara ceramique idashobora kwihanganira irashobora gukorwa hifashishijwe imashini isanzwe yumye cyangwa uburyo bwo gukanda isostatike hanyuma ukayicumura ku bushyuhe bwinshi mu itanura.Nibikoresho byifuzwa byifashishwa mubikoresho byo kwambara cyane bitewe nubunini busobanutse, ubwinshi bwinshi, ibirimo alumina nyinshi, uburinganire bwiza nubwiza buhamye.

Ingero zo Gukoresha

Inyandiko: Turashobora gutuma alumina yambara tile dukurikije ibyo usabwa.

Ibiranga

Gukomera cyane

Ubukomezi bwa Rockwell bwibumba bya alumina bigera kuri HRA80-90 ikaba iya kabiri nyuma ya diyama kandi irenze kure ibyuma bidashobora kwangirika.

Kurwanya kwambara neza

Kurwanya kwambara kumabumbe mwinshi ya alumina yikubye inshuro 266 icyuma cya manganese hamwe ninshuro 171.5 zicyuma cya chromium cyinshi. Dukurikije iperereza ryacu & dukurikirana kubakiriya, ubuzima bwibikorwa bwibikoresho bushobora kongerwa inshuro 10 mugihe kimwe imiterere y'akazi.

Kurwanya ruswa

Ceramics nyinshi ya alumina ni okiside ya organic organique ifite imiterere ya molekile ihamye cyane kandi nta ruswa ishobora kwangirika, bityo irashobora kurwanya isuri ya aside, alkali, ibisubizo byumunyu hamwe na Solvents organic.

Ubushuhe

Ubushyuhe bwo gukora bwa alumina ceramics irashobora kuba hejuru ya 1400 ℃.

Kwisiga neza

Ceramics yo hejuru ya alumina ifite imiterere yo kwikenura no kudashyira mu gaciro, ubukana ni 1/6 gusa cy'imiyoboro y'ibyuma bityo kugabanuka gake Kurwanya.

Uburemere bworoshye

Ubucucike bwibumba byinshi bya alumina ni 3.6g / cm3, ni kimwe cya kabiri cyibyuma, bityo byoroshye kubaka no gushiraho

Kwambara ibisubizo dutanga
