Intshayelelo yemveliso:

I-Honeycomb Ceramics luhlobo olutsha lwemveliso ye-ceramic kunye nesakhiwo esifana ne-honeycomb. Yenziwe ngezinto ezikrwada ezifana ne-kaolin, i-talc, umgubo we-aluminiyam, kunye nodongwe. Inemilo eyahlukahlukeneyo eyenziwe yimingxuma elinganayo. Inani eliphezulu lemingxuma lifikelele kwi-120-140 nge-square centimeter, ubuninzi be-0.3-0.6 grams nge-cubic centimeter, kwaye izinga lokufunxa amanzi liphezulu kwi-20%. Esi sakhiwo esinemingxuma esincinci esincinci sandisa kakhulu indawo yejometri yomphezulu womphathi kwaye siphucula ukuxhathisa ukothuka kwe-thermal. Imingxunya yemesh yekeramics ye-honeycomb ikakhulu inonxantathu kunye nesikweri, phakathi kwayo imingxuma engunxantathu inomthamo ongcono wokuthwala kunemingxuma esisikwere kunye nemingxuma engaphezulu, ebaluleke kakhulu njengesixhobo esithwala i-catalytic. Ngokunyuka kwenani lemingxuma kwindawo nganye yeyunithi kunye nokuncipha kobukhulu bodonga lwe-pore ye-carrier carrier, ukuxhathisa ukutshatyalaliswa kwe-thermal ye-ceramic carrier kuphuculwe, kwaye iqondo lokushisa lokutshatyalaliswa kokutshatyalaliswa kwe-thermal nalo linyuka. Ngoko ke, ii-ceramics ze-honeycomb kufuneka zinciphise i-coefficient yokwandisa kunye nokwandisa inani lemingxuma kwindawo yeyunithi.

Izixhobo eziphambili:

I-Cordierite, i-mullite, i-aluminium porcelain, i-alumina ephezulu, i-corundum, njl.

Ukusetyenziswa kwemveliso:

I-1) Njengomzimba wokugcina ubushushu: Umthamo wokushisa we-honeycomb ye-ceramic yokugcina ubushushu umzimba ungaphezulu kwe-1000kJ / kg, kwaye ubushushu obuphezulu bokusebenza kwemveliso ≥1700℃. Inokonga ngaphezu kwe-40% yepetroli kwiziko lokufudumeza, ii-roasters, iziko lokuntywila, iitofu eziqhekekileyo kunye nezinye iikloni, inyuse imveliso ngaphezulu kwe-15%, kwaye ubushushu berhasi yokuphuma bungaphantsi kwe-150 ℃.

2) Njengomhluzi: Izihluzi ze-ceramic ze-honeycomb zineenzuzo ezinjengendawo enkulu yendawo ethile kunye namandla angcono kunezinye iimilo zokuzalisa. Banokwenza ukuhanjiswa kwe-gas-liquid ngaphezulu ngokufanayo, ukunciphisa ukuxhatshazwa kwebhedi, kube nemiphumo engcono, kunye nokwandisa ubomi benkonzo. Zisebenza kakhulu njengezizalisi kwi-petrochemical, amayeza kunye namashishini amachiza afanelekileyo.

3) Njengomthwali we-catalyst: Iiceramics ze-honeycomb zineenzuzo ezininzi kwii-catalysts. Ukusebenzisa izinto ze-ceramic ze-honeycomb njengabathwali, besebenzisa izinto zokugquma ezikhethekileyo, kwaye zilungiswe ngeentsimbi ezixabisekileyo, isinyithi esinqabileyo somhlaba kunye neentsimbi zenguqu, zineenzuzo zomsebenzi ophezulu we-catalytic, ukuzinza okulungileyo kwe-thermal, ubomi benkonzo ende, amandla aphezulu, njl.

4) Njengezinto zokucoca: ukuzinza okulungileyo kweekhemikhali, ukumelana ne-asidi, i-alkali kunye ne-solvents eziphilayo; ukumelana okugqwesileyo kubushushu obukhawulezayo kunye nokupholisa, ubushushu bokusebenza bunokuba phezulu njenge-1000 ℃; iipropathi ezilungileyo ze-antibacterial, ezingonakaliswa lula yibhaktheriya, akulula ukuvalelwa kwaye kulula ukuyivuselela; uzinzo olomeleleyo lwesakhiwo, ukuhanjiswa kobungakanani bepore emxinwa, ukungeneka okuphezulu; non-toxic, ingakumbi ilungele ukutya kunye nokulungiswa kweziyobisi.
