Imikhiqizo
i-silicon nitride Riser3
Izici
● Enqubweni yokukhiqiza yemboni yokucubungula i-aluminium, kuvame ukuba nezigcawu ezidinga ukuvala uketshezi lwe-aluminium.I-Silicon nitride ceramics iyisinqumo esingcono kakhulu samapayipi okuvala ahlukahlukene (ama-valve) ngenxa yokuminyana kwawo okuphezulu, amandla amahle okushisa aphezulu, nokumelana nokushaqeka okuhle kakhulu okushisayo.
● Uma kuqhathaniswa ne-aluminiyamu titanate nezitsha zobumba ze-alumina, izitsha zobumba ze-silicon nitride zinokungagugi kangcono, okuqinisekisa ukuvalwa kwesikhathi eside kwamashubhu okuvala (amavalvu).
● Izitsha zobumba ze-silicon nitride zinamandla amahle kakhulu okushisa okuphezulu, okuqinisekisa ukuthi ipayipi elivaliwe (i-valve) lingasebenza ngokuzinza isikhathi eside ngaphansi kwezimo zokusebenza ezivamile.
● Ukumanzisa okuphansi nge-aluminium, kunciphisa i-slagging nokugwema ukungcoliswa kwe-aluminium.
● Uma ufaka okokuqala, sicela ulungise ngesineke idigri yokufanisa phakathi kwenduku yomkhawulo kanye nesihlalo se-valve.
● Ngezizathu zokuphepha, umkhiqizo kufanele ufudumale ngaphezu kuka-400°C ngaphambi kokusetshenziswa.
● Njengoba i-ceramic material ishwabana, umthelela onzima wokusebenza kufanele ugwenywe.Ngakho-ke, qaphela futhi uqaphele lapho uklama futhi ulungisa ukuhanjiswa kokuphakamisa.
