Isitini se-Corundum mullite

Izinzuzo zomkhiqizo: ukumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana ne-oxidation, ukuzinza okuhle kokushisa, kanye nezinga eliphansi lokushintsha komugqa.

Isicelo somkhiqizo: Isetshenziswa kakhulu embonini ye-petrochemical, i-ammonia gasifier enkulu kanye naphakathi nendawo yokwenziwa kwezinto zomlilo zegesi, okokushisa okuphezulu kwezimboni ezisekela izinto zokwakha, njll.

incazelo yomkhiqizo

Izitini zeCorundum ne-mullite zenziwe nge-high-purity corundum kanye ne-mullite njengezinto zokusetshenziswa, ezakhiwe ngcindezi ephezulu futhi zaqhuma emazingeni aphezulu okushisa. Umkhiqizo unezici zokumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana ne-oxidation, ukuzinza okuhle kokushisa, kanye nezinga eliphansi lokushintsha komugqa.

Incazelo yezitini ze-corundum mullite:

1. Izinto ezisindayo zinokuxinana okuhle, amandla acindezelayo aphezulu, ukumelana namagesi ahlukahlukene abhubhisayo, ukuzinza okuhle kokushisa okushisayo, ukuqhuba kahle kokushisa okushisayo, kanye nokumelana nokugqoka.

2. Izinto ezingasindi zinokwakheka okufanayo ngaphakathi, amandla acindezelayo aphezulu, ukumelana nokugqwala, ukumelana nokushaqeka kokushisa, ukumelana ne-oxidation, izinga lokushisa kwensizakalo ephezulu kanye nokuqhuba okuphansi kokushisa.
