Iifiber ze-ceramic refractory luhlobo lwezinto ezingaqhelekanga ze-porous kunye ne-complex micro spatial structure. Ukupakishwa kweefiber ku-random kwaye kuphazamisekile, kwaye le sakhiwo sejometri esingaqhelekanga sikhokelela ekuhlukeni kweempawu zabo zomzimba.
Ukuxinana kweFayibha
Iifiber ze-ceramic refractory ze-ceramic eziveliswa yindlela yokunyibilika kweglasi, ukuxinana kweentsinga kunokuthathwa njengokufana nokuxinana kokwenyani. Xa ubushushu bokuhlelwa buyi-1260 ℃, ubuninzi bemicu ye-refractory yi-2.5-2.6g/cm3, kwaye xa ubushushu bokuhlelwa buyi-1400 ℃, ubuninzi bemicu ye-ceramic refractory yi-2.8g/cm3. Iifiber ze-polycrystalline ezenziwe nge-aluminium oxide zinobunzima obuhlukeneyo bokwenyani ngenxa yobukho be-micro pores phakathi kweengqungquthela ze-microcrystalline ngaphakathi kwimicu.
Idayimitha yeFayibha
Idayimitha yefiber yeiifiber zeceramic ezichasayoeveliswa yindlela yokubumba yokubumba yobushushu obuphezulu benyibilika ukusuka kwi-2.5 ukuya kwi-3.5 μm. I-fiber diameter ye-refractory ceramic fibers eveliswa yindlela yokujikeleza ngokukhawuleza kweqondo eliphezulu lobushushu yi-3-5 μ m. Ububanzi bemicu ye-refractory ayihlali ngaphakathi kolu luhlu, kwaye ezininzi iifayili ziphakathi kwe-1-8 μm. Ububanzi beefiber ze-ceramic ezichasayo zichaphazela ngokuthe ngqo amandla kunye ne-thermal conductivity yeemveliso zefiber refractory. Xa i-diameter yefayibha imkhulu ngokwentelekiso, iimveliso zefiber refractory ziva nzima xa ziphathwa, kodwa ukonyuka kwamandla nako konyusa ukuhanjiswa kwe-thermal. Kwiimveliso zefiber refractory, i-thermal conductivity kunye namandla eentsinga zilingana ngokungafaniyo. Umyinge wedayamitha ye-alumina polycrystalline ngokubanzi yi-3 μ m. Idayamitha yobuninzi bemicu ye-ceramic echasayo iphakathi kwe-1-8 μ.
