Cov Qws Ceramic Zirconia Muaj Zog Siab - rau Cov Qws Precision & Punches
St.Cera tus pas nrig zirconia ceramic yog ua los ntawm yttria-stabilized ZrO₂. Nws muaj lub zog flexural zoo heev (1000 MPa), qhov tawg toughness (5–8 MPa·m¹/²), thiab Vickers hardness (13 GPa). Tus pas nrig muaj xim dub lossis dawb, qhov ceev 6.03 g/cm³, thiab xoom porosity. Txoj kab uas hla ntawm 1 hli txog 50 hli, ntev txog 200 hli, nrog rau kev kam rau siab li ±0.005 hli. Qhov tiav ntawm qhov chaw lapped rau Ra ≤0.2 μm. Zoo tagnrho rau cov ntawv thov hnav siab xws li plungers, shafts, dowel pins, thiab cov cuab yeej txiav blanks.

Cov ntawv thov:
- · Cov plungers thiab pistons precision
- · Cov pins rau kev sib dhos
- · Cov cuab yeej txiav (riam, slitters)
- · Cov menyuam kabmob hauv cov chaw muaj kuab paug
Cov txiaj ntsig:
- · Tsis yog hlau nplaum, hluav taws xob rwb thaiv tsev (>10¹³ Ω·mm²/m)
- · Tiv taus cov tshuaj lom neeg hnyav (acids, alkalis tshwj tsis yog HF)
- · Tsis muaj xeb los yog galling
Kev Tsim Khoom:
Cov pas nrig sintered → sib tsoo tsis muaj qhov chaw nruab nrab mus rau qhov txoj kab uas hla tseeb → lapping/polishing → ntxuav ultrasonic. Kev tshuaj xyuas 100% txoj kab uas hla nrog laser micrometer.
