Ibipimo by'imikorere n'ikoreshwa ry'amatafari ya Alumina Ceramic adashira

Amatafari ya alumina adashobora kwangirikani ibikoresho by'ibumba bikora neza bikozwe muri okiside ya aluminiyumu ifite isuku nyinshi (Al₂O₃) binyuze mu gukanda no gushyushya cyane. Ubusanzwe Al₂O₃ ifite ubunini bwa 92%, 95%, cyangwa 99%, hamwe n'ubucucike buri hagati ya 3.60 g/cm³ na 3.90 g/cm³ kandi amazi anyurwa munsi ya 0.01%. Ibikoresho bigaragaza ubukana bwinshi n'ubudahangarwa bwiza bwa shimi, bikwiranye n'inganda zirimo ingaruka, guhindagurika kw'ibintu, n'ibintu bihumanya.

Ibipimo bisanzwe by'imikorere: Ubukana bwa Mohs bwa 9, Ubukana bwa Rockwell HRA 85-90, no kudashira inshuro 20-30 z'icyuma gisanzwe cya karuboni (ingano y'ubusa ≤0.05 cm³ kuri ASTM G65 yumye umusenyi w'umuzunguruko w'umucanga). Ubukana bwo kuzunguruka bugera kuri 250-350 MPa, ubushyuhe bugera kuri 25-30 W/(m·K), kandi ubushyuhe bwo gukora buri hagati ya -50 °C na 1200 °C (bitewe n'urwego runaka). Aya makuru ahamya ko ari ingirakamaro mu gihe kirekire mu gihe cy'ubushyuhe bwinshi n'ubushyuhe bwinshi.

Iki gicuruzwa gikoreshwa cyane mu kurinda ubusaza bw'ibikoresho by'ingenzi mu nganda za sima, ibyuma, ingufu, ubucukuzi bw'amabuye y'agaciro, n'amakara, nk'ibyuma bigabanya ubushyuhe, imiyoboro y'amazi, imiyoboro y'amazi, imiyaga n'imigozi. Uburyo bwo gushyiraho burimo epoxy resin bonding, bolting, cyangwa gusudira (hakoreshejwe amatafari ya keramike yakozwe mbere hamwe n'amasahani ya rubber/icyuma). Ubunini busanzwe buri hagati ya mm 5 na mm 25; ingano zisanzwe z'amatafari zirimo 10 mm × 10 mm, 20 mm × 20 mm, na mm 50 × 50 mm kare cyangwa hexagonal kugira ngo byoroshye gukata no gushyiraho aho hantu.

Gukoresha amatafari ya alumina adashaje byongerera cyane igihe cyo gukoresha ibikoresho kandi bigabanya igihe cyo kubikora. Amakuru y’aho bikorera agaragaza ko mu gihe kimwe, amatafari ya ceramic amara igihe kingana n’inshuro 3-8 ugereranyije n’amatafari y’icyuma afite manganese nyinshi cyangwa amatafari ashaje adashaje. Iki gikoresho ntigikoresha ingufu za rukuruzi, kirwanya aside/alkali (usibye aside hydrofluoric na alkali ishyushye cyane), kandi nticyanduza ibikoresho. Guhitamo bigomba kugena ingano ya Al₂O₃ n’ubugari bw’amatafari hashingiwe ku nguni nyayo y’ingaruka, ingano y’uduce, n’ubushyuhe kugira ngo habeho uburinganire hagati y’imikorere n’ikiguzi.
