Ua npuas ncauj ceramic lim muaj qhov zoo ntawm qhov zoo thermal poob siab tsis kam, siab porosity, siab zog, zoo kub poob siab tsis kam, thiab tuaj yeem tiv taus qhov loj ntawm cov hlau kub pom. Yuav siv tau rau casting steel, tuaj yeem txo cov xuab zeb qhov, slag qhov, pores, inclusions thiab lwm yam tsis xws luag, txhim kho nto zoo ntawm castings, txhim kho machining kev ua tau zoo, txhim kho txhua yam khoom.
Ua npuas ncauj ceramic lim PPI, tus qauv yog qhia los ntawm P, thiab thoob ntiaj teb PPI yog qhia, uas yog hais, qhov pore ntom thiab pore uniformity ntawm cov khoom. Qhov nruab nrab tus naj npawb ntawm qhov nyob rau hauv ib chav tsev ntawm square inch ntev. Lub ppi ntawm no yog ib qho tshwj xeeb sawv cev ntawm lub mesh ntawm cov npuas dej ceramic lim, zoo ib yam li peb feem ntau hu ua "mesh". Ceramic lim 10ppi thiab 20ppi piv rau 10ppi, 10ppi aperture loj dua. 10ppi txhais tau tias muaj 10 mesh qhov ntawm qhov deb ntawm ib nti, thiab 20ppi txhais tau tias muaj 20 mesh qhov ntawm qhov deb ntawm ib nti. Qhov loj dua tus nqi PPI, lub qhov me me, thiab qhov loj dua tus nqi, qhov loj dua qhov.
