Umuyoboro wa Alumina Ceramic Rubber Udashira: Imiterere, Imiterere, n'Imikoreshereze

Umuyoboro wa alumina ceramic rubber udashobora kwangirika ni umuyoboro w’inganda ukorwa hifashishijwe uburyo bwo guhuza amatafari ya alumina ceramic akomeye cyane hamwe n’umuyoboro wa rubber woroshye binyuze mu buryo bwo gukurura. Umuyoboro wa alumina ceramic urimo ubukana bwinshi cyane (ubusanzwe ufite ibipimo bya Al₂O₃ bya ≥92%) ufite ubukana bwinshi cyane (ubukana bwa Rockwell HRA ≥88), ugaragaza ubukana bwinshi inshuro zirenga icumi z’icyuma gifite chromium nyinshi. Urupapuro rw’inyuma rwa rubber rutanga ubukana bwiza bworoshye no gufunga, bigatuma rushobora kunama no kwakira imitingito mu gihe cy’imikorere igoye. Iyi miterere y’imiterere ihuza neza ubukana bwa rubber n’ubukana bwa rubber, bigatuma ikoreshwa cyane cyane mu gutwara ibikoresho bikoresha ubukana bwinshi mu nganda nko mu bucukuzi bw’amabuye y’agaciro, mu gutanga amashanyarazi, no muri sima.

Ku bijyanye n'ibipimo by'imikorere, ibipimo bya tekiniki by'iki gicuruzwa biratandukanye bitewe n'ibisabwa mu ikoreshwa. Ubusanzwe urwego rwa ceramic rufite ubucucike bwa ≥3.6 g/cm³ n'imbaraga zo kugonda zirenga 290MPa. Nubwo rushobora kwihanganira ubushyuhe bwinshi kugeza kuri 1400°C, ubushyuhe bw'igihe kirekire bukoreshwa muri rusange bugenzurwa hagati ya -30°C na 150°C mu gihe gihoraho bitewe n'ubushyuhe buke bw'urwego rwa raba. Ibipimo by'imiyoboro birahindagurika, bifite uburebure buri hagati ya 25mm na 1200mm, uburebure bumwe kugeza kuri metero 20, n'igipimo cy'umuvuduko w'akazi kiri hagati ya 1MPa na 4MPa. Byongeye kandi, amatafari ya ceramic akenshi akozwe mu miterere ya hexagonal cyangwa uruziga kandi atunganyijwe neza kandi agashyirwa mu buryo bunoze kugira ngo urukuta rw'imbere rube rworoshye kandi rufite ubushobozi buke bwo kwirinda amazi.

Imiyoboro ya alumina ceramic irinda kwangirikazikoreshwa cyane mu buryo bwo gutwara ibikoresho by’amazi n’imyuka myinshi. Mu nganda zikoresha amakara, zikoreshwa mu gutwara ivu ry’umukungugu n’amakara yakuwemo umwuka. Mu nganda z’ibyuma, zikoreshwa mu gutera amakara yakuwemo umwuka no gutwara icyuma cy’ubutare. Mu rwego rw’imiti, hifashishijwe uburyo bwo kurwanya ingese bw’ibumba, izi myobo zishobora gutwara ibintu birimo aside, alkali, n’umunyu. Byongeye kandi, mu bikorwa byo gucukura imyanda no gupompa beto, uyu muyoboro, ufite ibyiza bibiri byo kudakora neza no kudakora neza, wongera cyane ukwezi kw’imiyoboro no kuyikoresha, bityo bikagabanya ikiguzi rusange cyo kuyikoresha no kuyitunganya.
