200 tons ntawm tsawg porosity av nplaum cib tau ntim rau xa mus rau peb cov neeg siv khoom hauv Saudi.
Cov av nplaum uas muaj porosity tsawg dua 18 feem pua yog cov av nplaum uas tsis muaj porosity. Muaj 16 feem pua, 12 feem pua, 15 feem pua, thiab 10 feem pua hom. Qhov qis qhov pores, tus nqi kim dua.
Nws cov yam ntxwv yog dab tsi? Lub zog siab, siab refractoriness, muaj zog compactness, tsawg pores, thiab zoo thermal shock stability. Feem ntau siv nyob rau hauv corrosive qhov chaw, vim hais tias ntawm nws anti-stripping yam ntxwv, ntau siv nyob rau hauv lub regenerator ntawm lub khob rauv.
Nws cov txheej txheem ntau lawm tsis nyuaj. Nyob rau hauv lub hauv paus ntawm ib txwm av nplaum cib tshuab, nws yog tsim los ntawm kev ntxiv scorched gemstones, sintered av nplaum thiab lwm yam khoom xyaw rau hauv raw cov ntaub ntawv nyob rau hauv ib tug tsim nyog piv los ntawm high-pressure molding thiab high-temperature sintering, tab sis sintering kub yog siab tshaj qhov ntawd. ntawm av nplaum cib. Nws yuav tsum yog li 30 degree siab dua.
Lub thermal zog ntawm av nplaum cib yog resistant rau ceev ceev txias thiab cua sov, tab sis tsawg-porosity av nplaum cib yog resistant rau ceev ceev txias thiab cua sov, raws li zoo raws li corrosion, tshwj xeeb tshaj yog acid corrosion. Lub zog thiab slag tsis kam ntawm cov av nplaum cib tsis zoo li cov av nplaum uas tsis muaj porosity, thiab lawv cov nqi khoom kuj tseem ntau dua li cov av nplaum zoo tib yam.
Qhov porosity ntawm cov av nplaum hloov dua siab tshiab yog feem ntau yog 24-26 feem pua , thaum cov av nplaum uas tsis muaj porosity feem ntau yog siv ntawm 12-16 feem pua , thiab cov porosity yog -10 feem pua . Txawm li cas los xij, vim yog tus nqi siab, nws tseem ceeb heev hauv cov xwm txheej tshwj xeeb. Tsuas yog siv 10 feem pua porosity rau ib feem.
Nws qhov porosity tsawg yog tsuas yog kho los ntawm scorched gemstone. Tom qab ntxiv cov scorched gemstone, nws yog ntom, thiab nws lub zog thiab corrosion kuj yog ob peb zaug ntawm cov av nplaum zoo tib yam. Nws cov firing thiab ntau lawm txheej txheem yog tib yam li cov av nplaum cib, tab sis sintering kub yog siab, cov raw khoom matrix hloov zoo heev, thiab corrosion kuj, thermal shock kuj thiab lub zog muaj zog tshaj av nplaum cib.
