Kodi Chosefera cha Ceramic Foam ndi Chiyani?

Mafotokozedwe Akatundu

Fyuluta ya thovu la ceramicYapangidwa kumene ngati mtundu watsopano wa zosefera zachitsulo chosungunuka kuti muchepetse vuto la kuponyera m'zaka zaposachedwa. Yapangidwa kuchokera ku zipangizo zapamwamba zadothi, zomwe zigawo zake zazikulu ndi Al2O3, Sic, ZrO2. Ceramic Foam Filter ili ndi kulemera kopepuka, mphamvu yayikulu yamakina, malo akuluakulu apadera, porosity yayikulu, kukana kutentha kwambiri, kukana dzimbiri ndi kutentha kwambiri mu chitsulo chosungunuka. Ndi kapangidwe kake ka ma pores ogawa, amatha kuwonjezera malo pamwamba, ndikuyamwa sinter, chitsulo chamadzimadzi chimakhala choyera kwambiri, mavuto amtundu wa zinthu monga mchenga ndi pores wa mpweya amachepa kwambiri ndipo mtundu wa cast umakhala wabwino kwambiri.

Zinthu zazikulu

1. Aluminiyamu

2. Slica carbide

3. Zirconia

Fyuluta ya thovu ya Alumina ceramic ndi mtundu watsopano wa kachulukidwe kochepa, ma porosity apamwamba komanso kapangidwe ka mafupa a fyuluta yokhala ndi magawo atatu. Ndipo imagwiritsidwa ntchito kwambiri mumakampani opanga aluminiyamu popangira zosefera za aluminiyamu yosungunuka, kuti iwonjezere ubwino wa aluminiyamu. Fyuluta ya thovu ya Alumina ceramic imatha kuchotsa bwino chisakanizo cholimba chosakhala chachitsulo kuchokera ku aluminiyamu ndi aluminiyamu alloy fusant, kuchepetsa mpweya wotsekeka ndikupereka kuyenda kwa laminar kenako chitsulo chosefedwa chimakhala choyera kwambiri. Chitsulo chotsukira chimapangitsa kuti zinthu zikhale zapamwamba kwambiri, zinyalala zochepa, komanso zolakwika zochepa zophatikizidwa, kuti chiwongolere mtundu wa aluminiyamu alloy ndi zina zopanda ferrous alloy casting, zonse zomwe zimathandiza kuchepetsa mtengo wopangira, kutentha kwake kwakukulu kwa ntchito 1200°C.

Kugwiritsa Ntchito Mankhwala

Amagwiritsidwa ntchito kwambiri posefa zitsulo zosiyanasiyana zoponyera ndi chitsulo chachikulu choponyedwa, zida zoponyera za master alloy ndi ndege zoponyedwa, zida zamaginito, ndi minda yoponyera yachitsulo yopanda chitsulo chopanda mphamvu.

Ubwino wa Zamalonda

1. Kapangidwe: kapangidwe ka netiweki ya magawo atatu, kukonza bwino ndi kudzaza. Netiweki ya magawo atatu yapamwamba, yapakati ndi yapansi ilibe mabowo otsekedwa, mabowo osawona, kuchepetsa mphamvu ya eddy, kuyenda kwa laminar, ndi kudzaza kokhazikika.
2. Kusefa: Njira yodutsa, kutsekereza bwino kwa slag yamakina Pali mipata yaying'ono kwambiri, kulowetsedwa kwamphamvu kwa slag, kusefa kogwira mtima, kuphatikiza kwa oxide, slag ndi zinyalala zina zazikulu.
3. Kagwiridwe ka ntchito: Malo akuluakulu amkati mwa fyuluta. Grout ndi yokwanira komanso yopanda mabowo akhungu, imapanga njira yonse yolimbikitsira ma pore yokhala ndi magawo atatu, yomwe imayamwa ma micro-inclusions.
