Zingakanani izitini zokwakha izinsimbi ezingasindi ezingamelana mullite?

Isitini se-Mullite se-insulation siwuhlobo olusha lwezinto ezakhayo, ezingathinta ngqo ilangabi. Inezici zokumelana nokushisa okuphezulu, ukukhanya okuphezulu, ukuqhuba okuphansi kokushisa, nomphumela omkhulu wokonga amandla. Izitini ze-Mullite ezingasindi kakhulu zinokusebenza okuhle okushisa okuphezulu nezindleko eziphansi. Zingasetshenziselwa ukugoqwa komlilo, okunganciphisi kuphela ikhwalithi yomzimba wesithando somlilo, ukusindisa ukuthungela, kepha futhi kunwebe impilo yenkonzo yesakhiwo sesithando somlilo nokunciphisa izindleko zesondlo.

Izitini ze-Mullite lightweight light insulation ikakhulukazi zenziwe nge-bauxite, ubumba, “amatshe amathathu”, njll., Ngokwakhiwa kwenani elikhulu lama-pores axhunyiwe noma avaliwe ekwakhiweni kokubumba kwempahla noma inqubo yokushisa okushisa okuphezulu.

Izici ze-mullite lightweight light izitini:

Zingakanani izitini zokwakha izinsimbi ezingasindi ezingamelana mullite? Ukumelana nokushisa okuphezulu kwesitini se-mullite light insulation kungafinyelela ngenhla kwe-1790 ℃. Ukushisa kokuqala kokulayisha kungu-1600-1700 ℃, amandla okushisa ajwayelekile okucindezela angama-70-260MPa, ukumelana nokushaqeka okushisayo kuhle, amandla aphakeme, izinga lokushisa eliphakeme lokushisa liphansi, i-coefficient yokwandisa iphansi, i-coefficient yokushisa incane, futhi i-acid slag ayizweli. Futhi inganciphisa kakhulu isisindo somzimba oshisa kakhulu esithandweni somlilo, iguqule isakhiwo, yonge izinto, yonge amandla, futhi ithuthukise ukusebenza kahle kokukhiqiza.

Isicelo uhla mullite engasindi izitini ukwahlukanisa:

Izitini ze-Mullite ezisindayo ezingasetshenziswanga ikakhulukazi zisetshenziselwa ukubasa okushisa okuphezulu ngaphezu kwe-1400 ℃, uphahla lwesithando esisezingeni eliphakeme kakhulu, imingcele yangaphambilini, imengamo yokuvuselela kabusha, izakhiwo zezingilazi ezincibilikisa ingilazi, izikhuni zokubumba zobumba, ama-ceramic roller kilns, ama-tunnel kilns, Ingaphakathi le-porcelain kagesi ikhabethe ledilowa, ikona elifile lesithando somlilo ulwelwesi lohlelo lokuqhekeka kukaphethiloli, ingilazi ebethelwa ingilazi namahhavini ahlukahlukene kagesi angaxhumana ngqo nelangabi.

Izinkomba zomzimba nezamakhemikhali zesitini semullite light insulation:
