Yuav Ua Li Cas Xaiv Foam Ceramic Lim?

I. Cov Qhov Tseem Ceeb Tom Qab Tus Qauv Zauv

Qhov sib txawv ntawm foam ceramic lim qauv feem ntau txhais los ntawm peb qhov ntev:

● Pore Density: Feem ntau ntawm 10 mus rau 60 PPI (pores ib nti). Tus nqi siab dua qhia pom qhov tseeb dua, txawm tias nws ua rau txo qis qis.

● Cov Khoom Siv: Alumina-raws li cov ntaub ntawv tsim nyog rau siab- cov ntawv thov kub hnyiab, thaum silicon carbide- cov ntaub ntawv raws li muaj kev tiv thaiv zoo rau cov kua qaub thiab alkalis.

● Dimensions: Lub voj voog lim feem ntau yog nyob ntawm 50 mus rau 300 mm nyob rau hauv txoj kab uas hla, thaum cov lim square tuaj yeem ncav cuag 600 mm.

 

II. Sib piv cov lim rau cov ntawv thov tshwj xeeb

Xaiv cov lim txoj cai raws li kev khiav hauj lwm ib puag ncig kom ua tau zoo tshaj plaws:

● Molten Hlau Lim: Xaiv 30–40 PPI alumina-raws li cov ntxaij lim dej, muaj peev xwm tiv taus qhov kub siab tshaj 1300 degree.

● Kev kho cov dej khib nyiab: Xaiv 20–30 PPI silicon carbide- raws li cov lim dej, uas muaj kev tiv thaiv corrosion zoo heev.

● Khoom noj khoom haus-Qib lim: Yuav tsum tsis muaj coated, ntshiab-alumina lim, xav tau ntau dua ntawm pore uniformity.

 

III. Zam Txim Peb Qhov Tseem Ceeb

Cov kev xav tsis zoo no tuaj yeem cuam tshuam qhov ua tau zoo ntawm koj cov txheej txheem pom:

● Qhov muag tsis pom kev Pursuing High Precision: Siv 50 PPI lim rau molten aluminium filtration yuav ua rau tus nqi qis heev.

● Tsis quav ntsej Thermal Expansion Coefficients: Hauv qhov chaw siab - qhov kub thiab txias, qhov sib txawv ntawm qhov sib txawv los ntawm thermal expansion tuaj yeem ncav cuag li 2%.

● Tshaj Tawm Rov Siv Dua: Feem ntau, tom qab 3 mus rau 5 lub voj voog lim, cov pores yuav raug deformation mus tas li.
