High-Precision Zirconia Ceramic Scraper
Manufactured from premium yttria-stabilized zirconia (YSZ) ceramic using advanced pressing, sintering, and precision edge grinding/polishing processes, Meetcera zirconia scraper blades offer unmatched durability, clean wiping performance, and zero contamination in demanding applications.
Key Performance Highlights
- Exceptional hardness & abrasion resistance: Far superior to steel or alumina blades, especially against abrasive inks, slurries, or coatings
- Superior chemical inertness: Non-reactive with acids, alkalis, solvents, water-based/UV inks — no corrosion, no metal ion leaching
- High edge sharpness & retention: Maintains consistent, clean metering/wiping over extended runs; minimal streaking or buildup
- Excellent thermal & dimensional stability: Low expansion, good thermal shock resistance, suitable for high-speed or heated processes
Typical Application Scenarios
- Doctor blades for flexographic printing: Precise ink metering on ceramic anilox rolls, especially with abrasive or high-pigment inks
- Coating & film application: Uniform thin-film deposition in battery slurries, solar cells, functional coatings, lab-scale tape casting
- Precision scraping in electronics & semiconductor: Slurry/ paste removal, wafer processing, or cleanroom-compatible tools
- Laboratory & R&D: Scratch-free scraping of viscous materials, adhesives, paints, or nanomaterials without contamination

FAQ
Q1: Why choose zirconia ceramic scraper blades over steel or coated metal doctor blades?
A: Zirconia provides dramatically longer life (often 5–20×) in abrasive conditions, complete non-metallic/non-contaminating performance, superior edge retention, and no risk of scoring delicate anilox rolls or substrates.
Q2: What handling precautions are recommended?
A: Avoid mechanical impacts or dropping (ceramic is hard but brittle); use gentle cleaning (ultrasonic or solvent wipe); control thermal gradients (ramp ≤10°C/min if heated); ensure proper blade angle/pressure setup to prevent chipping.
Q3: Can Meetcera customize blade dimensions and edge profiles?
A: Yes — full customization: lengths 10–500+ mm, widths 10–50 mm, thicknesses 0.1–2 mm, various edge geometries (square, beveled, rounded tip), tolerances ±0.01 mm, and special coatings/polishing. Provide drawings for quick quoting.
