Imiyoboro ya Alumina Ceramic Liner Idashira: Igisubizo cyizewe ku bidukikije byo mu nganda

Imiyoboro y'icyuma cya alumina idashirani igice cy'ingenzi cy'uburinzi gikoreshwa cyane mu miyoboro y'inganda ishobora kwangirika cyane. Ibigize byayo by'ibanze ni alpha-alumina (Al₂O₃), aho ubusanzwe ingano yayo iri hagati ya 92% na 99.5%. Iki gikoresho gikorwa binyuze mu buryo bwo gushyushya cyane, bigatuma habaho ubukana budasanzwe, hamwe n'ubukana bwa Rockwell (HRA) bwa ≥85 n'ubukana bwa Mohs bwa 9, bukurikira diyama gusa. Iyi miyoboro ifatanye neza cyangwa ishyirwa mu buryo bwa mashini ku rukuta rw'imbere rw'imiyoboro y'icyuma, igakora uruzitiro rukomeye rurinda rutandukanya neza icyuma gitemba n'ingufu ku mubiri w'umuyoboro w'icyuma.

Imikorere yazo ihebuje ikomoka ku miterere y’ibikoresho bya alumina ceramics. Uretse ubukana bwinshi, ubucucike bwazo busanzwe buri >3.6 g/cm³, kandi imbaraga zo gukanda zirenga 850 MPa. Ubudahangarwa bw’ibi bikoresho bya ceramic bungana n’inshuro 266 z’icyuma cya manganese n’inshuro 171.5 z’icyuma cya chromium cast steel, bikongera igihe cyo gukoresha ibikoresho inshuro 5 kugeza ku 10 mu gihe cy’imikorere nk’iyo. Ubuso bwazo bworoshye n’ubushobozi buke bwo gukanda bigabanya ubushobozi bwo gutwara ibintu. Bifite kandi ubushobozi bwo kudahangarwa neza n’ubukana, bihangana n’ibintu byinshi bya chemical uretse aside hydrofluoric na alkali nyinshi zishyushye.

Iki gicuruzwa gikoreshwa cyane cyane mu nganda zifite ibisabwa bikomeye byo kudashira. Ikoreshwa risanzwe ririmo gutwara amakara, gutanga lisansi ivanze, n'uburyo bwo gukuraho ivu mu nganda zikoresha ubushyuhe; imiyoboro yo gutwara ifu y'amakara n'amabuye y'agaciro ivanze mu nganda z'ibyuma; imiyoboro yo kohereza ifu y'amakara, ifu ya clinker, n'iy'amakara mu nganda za sima; hamwe n'uburyo bwo gutwara ifu y'amakara mu bucukuzi bw'amabuye y'agaciro. Kinakoreshwa cyane mu miyoboro itwara amazi n'amazi mu nganda zikora ibyuma, imiti n'izindi, bityo bigakemura ibibazo byihuse byo kwangirika kw'imiyoboro, gutobora no gusohoka kw'amazi guterwa no gusya ibikoresho igihe kirekire.

Muri make, imiyoboro ya alumina ceramic idashobora kwangirika itanga uburinzi bw'igihe kirekire ku miyoboro itwara amashanyarazi mu nganda bitewe n'ubukana bwayo bukabije, kwangirika kwayo kudasanzwe, no kudatwarwa n'ingufu. Bigabanya cyane inshuro zo gufunga ikiguzi cyo kubungabunga no gusimbuza imiyoboro, bikongera imikorere myiza n'umutekano w'imikorere ya sisitemu. Ni igisubizo cy'uburinzi cyagaragaye kandi gihendutse.
