Sib tham txog Honeycomb ceramics

Khoom taw qhia:

Honeycomb ceramics yog hom tshiab ntawm cov khoom siv ceramic nrog cov qauv zoo li honeycomb. Nws yog tsim los ntawm cov khoom siv raw xws li kaolin, talc, aluminium hmoov, thiab av nplaum. Nws muaj ntau yam duab uas suav tsis txheeb qhov sib npaug. Qhov siab tshaj plaws ntawm qhov tau mus txog 120-140 ib square centimeter, qhov ceev yog 0.3-0.6 grams ib cubic centimeter, thiab tus nqi nqus dej yog siab li 20%. Qhov no ntxeem tau nyias-walled qauv zoo heev tsub kom lub geometric nto cheeb tsam ntawm cov cab kuj thiab txhim kho lub thermal shock kuj. Lub mesh qhov ntawm honeycomb ceramics feem ntau yog daim duab peb sab thiab square, ntawm cov duab peb sab qhov muaj peev xwm ua tau zoo dua li cov square qhov thiab ntau qhov, uas yog qhov tseem ceeb tshwj xeeb tshaj yog cov cab kuj catalytic. Nrog rau qhov nce ntawm tus naj npawb ntawm qhov ib cheeb tsam thiab qhov txo qis ntawm lub thickness ntawm cov cab kuj pore phab ntsa, thermal poob siab kuj ntawm cov cab kuj ceramic yog txhim kho, thiab qhov kub ntawm thermal shock puas kuj nce. Yog li ntawd, honeycomb ceramics yuav tsum txo cov expansion coefficient thiab ua rau kom tus naj npawb ntawm qhov ib cheeb tsam.

Cov ntaub ntawv tseem ceeb:

Cordierite, mullite, aluminium porcelain, siab alumina, corundum, thiab lwm yam.

Khoom siv:

1) Raws li lub cev kub cia: Lub peev xwm kub ntawm honeycomb ceramic kub cia lub cev yog ntau tshaj 1000kJ / kg, thiab qhov siab tshaj plaws ua haujlwm kub ntawm cov khoom yog ≥1700 ℃. Nws tuaj yeem txuag tau ntau dua 40% ntawm cov roj hauv cov cua kub cua sov, cov roasters, cov cua sov so, tawg rauv thiab lwm yam kiln, nce ntau lawm ntau dua 15%, thiab cov pa cua kub qis dua 150 ℃.

2) Raws li kev muab tub lim: Honeycomb ceramic fillers muaj qhov zoo xws li qhov loj dua qhov chaw thiab lub zog zoo dua li lwm cov duab ntawm cov khoom siv. Lawv tuaj yeem ua rau cov roj-kua faib ua kom zoo dua qub, txo lub txaj tiv thaiv, muaj kev cuam tshuam zoo dua, thiab txuas ntxiv lub neej kev pab cuam. Lawv ua tau zoo heev li fillers nyob rau hauv petrochemical, tshuaj thiab zoo tshuaj industries.

3) Raws li cov cab kuj catalyst: Honeycomb ceramics muaj ntau qhov zoo hauv catalysts. Siv cov khoom siv honeycomb ceramic ua cov nqa khoom, siv cov khoom siv tshwj xeeb txheej, thiab npaj nrog cov hlau muaj txiaj ntsig, cov hlau tsis tshua muaj hauv ntiaj teb thiab cov hlau hloov pauv, lawv muaj qhov zoo ntawm kev ua haujlwm siab catalytic, zoo thermal stability, ntev kev pab cuam lub neej, siab zog, thiab lwm yam.

4) Raws li cov khoom siv lim dej: tshuaj lom neeg ruaj khov, tiv taus cov kua qaub, alkali thiab cov kuab tshuaj organic; zoo heev tiv taus cua kub ceev thiab txias, ua hauj lwm kub yuav siab li 1000 ℃; zoo antibacterial zog, tsis yooj yim degraded los ntawm cov kab mob, tsis yooj yim rau raug thaiv thiab yooj yim rau regenerate; muaj zog structural stability, nqaim pore loj faib, siab permeability; non-toxic, tshwj xeeb tshaj yog haum rau kev ua zaub mov thiab tshuaj.
