Kulolu daba sizoqhubeka nokwethula izinto zokuvimbela i-fibre ezingasetshenziswa ekwakheni isithando somlilo
1) I-fibre evuselelayo
I-fibre ephikisayo, eyaziwa nangokuthi i-ceramic fiber, uhlobo lwezinto ezingezona ezensimbi ezenziwe ngumuntu, okuyi-binary compound yesigaba seglasi noma sekristalu eyakhiwe yi-Al2O3 kanye ne-SiO2 njengezingxenye eziyinhloko. Njengezinto zokuvikela eziphikisayo ezilula, ingonga amandla ngo-15-30% uma isetshenziswa ezithandweni zezimboni. I-fibre ephikisayo inezici ezinhle ezilandelayo:
(1) Ukumelana nokushisa okuphezulu. Izinga lokushisa lokusebenza le-fiber ejwayelekile ye-aluminium silicate refractory lingu-1200°C, kanti izinga lokushisa lokusebenza le-fiber ekhethekile refractory njenge-alumina fiber kanye ne-mullite liphakeme njengo-1600-2000°C, kanti izinga lokushisa eliphikisayo lezinto ezijwayelekile ze-fiber njenge-asbestos kanye noboya bedwala licishe libe ngu-650°C kuphela.
(2) Ukushisa okushisayo. Ukushisa okushisayo kwefayibha ephikisayo kuphansi kakhulu ekushiseni okuphezulu, kanti ukushisa okushisayo kwefayibha evamile ephikisayo ye-aluminium silicate ku-1000 °C kuyi-1/3 yezitini zobumba ezilula, futhi amandla ayo okushisa mancane, ukusebenza kahle kokushisa okushisayo kuphezulu. Ubukhulu bendwangu yesithando eklanyelwe bungancishiswa cishe ngesigamu uma kuqhathaniswa nokusetshenziswa kwezitini eziphikisayo ezilula.
Udaba olulandelayo sizoqhubeka nolwethulaizinto zokuvimbela i-fibre eziphikisayoisetshenziswa ekwakheni isithando somlilo. Sicela uhlale ubukele!
