Whakaahuatanga Castable Corundum Mullite
Corundum mullite refractory castable ko te ahua o te kaha teitei rauemi refractory unshaped mo te hoko i roto i te Kamupene RS, e taea te whakamahi i roto i te umu sima. Ka taea e Corundum mullite castables te mahi i nga taonga teitei penei i te kaha kuru nui, te pumau o te pāmahana teitei, te parenga waiariki, te kakahu me te aukati matū i roto i te raima o te teihana hiko nui me etahi atu taputapu pāmahana teitei. Ka taea te whakamahi i te corundum mullite castable i roto i te oumu maitai, te umu sima, te oumu karaihe, te oumu hanga rino, te oumu tunnel ceramic me etahi atu.
Nga Taonga o Corundum Mullite Castable
- Te kaha teitei,
- He kaha te whakakakahu,
- He pai te aukati i te horo,
- He pai te pumau o te ru werawera,
- Te ātete pāmahana teitei.
Tukanga Hangahanga o Corundum Mullite Castable
Ko nga mea matua o te corundum mullite castable he konumohe konumohe waikura aggregate, te kounga teitei parakore mullite ore taiao, me te konupūmā aluminate sima hei kaihoko hononga. Ka hangaia te corundum mullite refractory castable na roto i te wera wera nui e te oumu ahumahi matatau. Ko te kaha flexural corundum mullite me te kaha compressive ka piki i te tuatahi ka heke katahi ka piki ake te pāmahana maimoatanga wera. A, ki te 5% te ihirangi hiko moroiti alumina, ka eke te kaha flexible ki runga.
Tito o Corundum Mullite Castable
Ko te ihirangi o Al2O3 he neke atu i te 90%, me te corundum mullite insulation castable ki corundum rite te wāhanga karaihe matua i konatunatua ki dispersants tika, coagulants, muka kowiri tira, e kua pūhui rite ki te tātai tino. He maha nga ahuatanga o te corundum mullite castable he maha nga ahuatanga, penei i te kaha o te wera nui, te whakakakahu me te anti-scour, te wera nui o te wera, te awangawanga wera, te aukati waikura, te pai o te hiri me te tohe moata.

Te tono mo te Corundum Mullite Castable
Ko te corundum mullite refractory castable he ahuatanga o te roha orite, he pai te awangawanga o te waiariki, te teitei o te pāmahana teitei, te kaha teitei o te pāmahana, te kaha o te kaha ki raro i te kawenga, te tere o te ngokingoki o te pāmahana teitei, te kaha o te kuru, te iti o te reeti huringa ahu, te pakeke teitei, te pai. te ātete ki te waikura matū, te pakaru me te mau kakahu. Na te ahua o enei ahuatanga, me te corundum mullite insulation castable he roa ki te whakamahi me te whanui e whakamahia ana i roto i nga umanga rereke rereke, oumu teitei teitei me etahi atu waahanga nui o te pāmahana teitei, penei:
- Kohua, oumu pupuhi, umu wera wera, oumu whakamahana,
- Umu tunnel Ceramic, umu sima, tahu waro,
- Te tatau umu, te whakatuwhera kai, te oumu rino, te oumu hanga rino,
- ruma ngingiha, rere anga,
- Kohuatanga teihana hiko nui, umu karaihe.
