Amatafari yoroheje ya Mullite: Ibisobanuro, Imikoreshereze n'Ibyiza by'ingenzi

Nk'igikoresho gikonjesha kandi gikora neza,amatafari yoroheje ya mulliteBikunzwe cyane mu nganda ku isi kubera ubushobozi bwazo bwo gukingira ubushyuhe, kurwanya ubushyuhe bwinshi, ndetse n’imiterere yoroheje. Ayo matafari yagenewe kuzuza ibisabwa cyane by’ibikoresho bikoresha ubushyuhe bwinshi, ntabwo agabanya gusa ikoreshwa ry’ingufu ahubwo ananongera igihe cyo gukoresha amatanura y’inganda, bigatuma aba amahitamo meza ku bigo biharanira imikorere myiza n’iterambere rirambye.

Ibipimo by'amatafari yoroheje ya mullite birasanzwe kandi bihindurwa kugira ngo bihuzwe n'imiterere itandukanye y'inganda. Imiterere y'ingenzi irimo JM23, JM25, JM26, JM27, JM28, JM30, na JM32, ifite alumina iri hagati ya 40% na 77% kandi ingano ya oxide y'icyuma ntirenze 1.0% (kugeza kuri 0.5% ku miterere ifite isuku nyinshi). Ubucucike bwazo ni 0.55g/cm³ kugeza 1.35g/cm³, kandi imbaraga zo gusya ubukonje ni 1.0MPa kugeza 3.5MPa, bitanga umusaruro uhamye mu bihe bitandukanye by'imitwaro. Ubushyuhe bwo gushyira mu byiciro ni 1260℃ kugeza 1760℃, ubushyuhe bwo gutangira koroshya imitwaro ni 1080℃ kugeza 1570℃, kandi igipimo gihoraho cyo guhindura umurongo nyuma yo gushyushya ubushyuhe bwinshi ni -1.5% kugeza 0.5%. Ingano isanzwe ni 230x114x65mm, kandi ingano zihariye ziraboneka hakurikijwe ibyo abakiriya bakeneye ku bw'amabuye y'agaciro adatekanye.

Ubushyuhe bw'amatafari yoroheje ya mullite buri hasi ya 0.18W/(m·K) kuri 200°C, bishobora kugabanya ubushyuhe no kunoza ikoreshwa ry'ingufu—akamaro k'ingenzi mu nganda. Akozwe muri alumina na silica ifite pure nyinshi, aya matafari akora imiterere ya mullite ihamye, irimo ingano nto y'ikirahure, cristobalite, cyangwa corundum, byongerera cyane ubushyuhe bwayo no kurwanya ingese. Ashobora guhura n'inkongi z'umuriro, bigatuma hadakenerwa izindi nganda zirinda ubushyuhe kandi byoroshya inzira yo kubaka.

Amatafari yoroheje ya mullite afite akamaro kanini, akoreshwa mu byuma, ibumba, ibirahure, peteroli n'izindi nganda. Mu nganda zikora ibyuma, akoreshwa mu gushyiramo amatafari ashyushye, imiyoboro n'ibice byo hasi by'amatafari, ndetse no mu gukora ibyuma hejuru y'amatafari akoresha amashanyarazi, ibyo bikaba bidafasha gusa mu kubungabunga ubushyuhe buhamye ahubwo binagabanya ikoreshwa ry'ingufu. Mu nganda zikora ibyuma, ni ibikoresho byiza ku matafari akoresha amatafari, amatafari akoresha amatafari, n'amatafari akoresha amatafari, bigatuma habaho gushyuha no gukonjesha vuba kandi bikanoza umusaruro.

Mu nganda z'ibirahuri, zikoreshwa mu byuma bihindura ifuru bishongesha ibirahuri n'imiyoboro y'ibiryo, bishobora kurwanya ubushyuhe bwinshi n'isuri kugira ngo bigerweho neza. Mu nganda zikora ibikomoka kuri peteroli, zikoreshwa mu gushyira mu nganda amatanura acukurwamo peteroli, amatanura ahindura ammonia, n'amatanura ahindura ibisigazwa by'amavuta, ashobora kwihanganira ibidukikije bikomeye. Byongeye kandi, zikoreshwa cyane mu matanura atandukanye y'amashanyarazi, amatanura, n'ibikoresho bikoresha ubushyuhe bwinshi, bitanga ubushyuhe bwizewe kandi bishyigikira imiterere y'ibirahuri.

Ugereranyije n'amatafari asanzwe akoreshwa mu kugabanya ubushyuhe, amatafari yoroheje afite ibyiza bifatika: ubucucike buke bushobora kugabanya uburemere bw'itanura n'umutwaro w'inyubako, ubushyuhe buke bushobora kuzigama 15%-20% bya lisansi, kandi isuku nyinshi ituma habaho imikorere ihamye mu kirere kigoye. Byaba ari ibipimo bisanzwe cyangwa ibipimo byihariye, bishobora guhaza ibyifuzo bitandukanye by'inganda zitandukanye. Hitamo amatafari yacu meza yoroshye kugira ngo agufashe kugabanya ikiguzi cy'imikorere, kunoza imikorere, no kugera ku iterambere rirambye.
