Mtengenezaji wa Mpira wa Kauri wa Porous na ukubwa tofauti
Maombi
Mpira wa kauri wa porous ni bidhaa mpya iliyotengenezwa kwa msingi wa mpira wa kauri wa alumina isiyo na nguvu.Inachukua kipenyo cha mpira kama mhimili kufungua shimo.Sio tu kuwa na nguvu fulani za mitambo, utulivu wa kemikali na utulivu wa joto, lakini pia huongeza eneo maalum la uso.Na uwiano wa utupu, na hivyo kuongeza utawanyiko na flux ya nyenzo, na kupunguza upinzani wa mfumo.Inaweza kutumika sana katika tasnia ya petroli, kemikali na gesi asilia kuchukua nafasi ya mipira ya kauri ya alumini ajizi kama vijazaji vya vichocheo vya kufunika.
