Core Performance Thiab Technical Specifications Ntawm Zirconia Ceramic Foam Lim

1. Thermal Resistance: Zirconia ceramic ua npuas ncauj lim qhia tshwj xeeb siab - kub stability. Lawv qhov kev pabcuam kub siab tshaj plaws yog li ntawm 1700℃txog 1760 degree, nrog rau qee qhov siab - qib purity muaj peev xwm tiv taus qhov kub thiab txias li 1780 degree, ua rau lawv zoo tagnrho rau qhov kub ntawm -kub molten steel ib puag ncig.

2. Cov Khoom Siv: Feem ntau yog tsim los ntawm kev sib xyaw ntawm ZrO2-raws li ceramic hais thiab additives (xws li alumina hmoov thiab yttria hmoov), cov ntxaij lim dej no yog tsim los ntawm cov txheej txheem organic foam impregnation los tsim peb-dimensional, interconnected porous network qauv.

3. Specifications thiab Models: Pore density feem ntau qhia hauv PPI (Pores Ib Nti). Common specifications muaj xws li:

* 10 PPI: Haum rau cov khoom siv hlau, cov hlau loj loj, thiab cov hlau castings; lim impurities nrog txoj kab uas hla ntawm kwv yees li 80 μm.

* 20 PPI: Siv rau malleable hlau castings, me me grey hlau castings, thiab tsis yog -ferrous alloy castings; lim impurities nrog txoj kab uas hla ntawm kwv yees li 40 μm.

* 30 PPI thiab Saum toj no: Ua haujlwm rau tooj liab alloy thiab aluminium alloy castings, nrog rau kev siv precision casting; muaj peev xwm lim txawm finer impurities nrog diameters tsawg tshaj li 20 μm.
