ジルコニアセラミック射出ポンプの利点とは？

---

Zirconia ceramic injection pump is a high-performance fluid transport equipment, with its core components made of zirconia (ZrO ₂) ceramic material. This material is processed through advanced powder metallurgy and sintering processes, possessing excellent physical and chemical properties, and is widely used in fields such as chemical engineering, pharmaceuticals, food processing, semiconductors, and new energy.

製品応用分野
Zirconia ceramic injection pumps play a key role in multiple industrial fields, and their application scenarios include:

1. 化学産業： used for transporting corrosive media (such as acids, bases, organic solvents), replacing traditional metal pumps in chlor alkali production or pesticide synthesis.
2. Pharmaceutical and Bioengineering: To avoid contamination risks in aseptic filling, vaccine production, or high-purity drug delivery.
3. 食品加工： Transport highly acidic or high-temperature liquids (such as juices and sauces) that comply with food safety standards.
4. Semiconductors and Electronics: Prevent ion contamination during the transportation of ultrapure water or chemical mechanical polishing (CMP) slurries.
5. 新エネルギー used for lithium battery electrolyte injection to ensure high precision and safety.
   These applications fully demonstrate the reliability and adaptability of zirconia ceramic injection pumps.

Core advantages of the product
The advantages of zirconia ceramic injection pumps stem from their material properties and engineering design, which are reflected in the following aspects:

1. 優れた耐食性
   -Principle: Zirconia is an inert ceramic with a stable crystal structure that can resist strong acids (such as hydrochloric acid, sulfuric acid), strong bases, and organic solvents.
   -Data support: According to ASTM G31 standard testing, in a hydrochloric acid environment with pH=1, the annual corrosion rate is less than 0.01mm, which is much better than 316 stainless steel (annual corrosion rate>0.5mm).
   -Problem solved: Extend the lifespan of the pump body, reduce equipment failures and medium pollution caused by corrosion.
2. Extremely high wear resistance
   -Principle: Zirconia ceramics have a Vickers hardness of 12-13 GPa and a low friction coefficient (approximately 0.1-0.15).
   -Data support: In the slurry transportation test, the wear amount is only one-third of that of silicon carbide ceramics, and the service life can be increased to more than 5 times that of metal pumps.
   -Problem solved: Suitable for media containing particulate matter (such as CMP slurry), reducing maintenance frequency and cost.
3. 優れた高温耐性と熱安定性
   -Principle: Zirconia has a melting point of 2700 ° C, a low coefficient of thermal expansion (~10 × 10 ⁻⁶/K), and can maintain structural integrity at high temperatures.
   -Data support: The long-term working temperature can reach 400 ° C, and the short-term tolerance is 800 ° C (refer to the Advanced Ceramic Materials Manual).
   -Problem solved: Suitable for high-temperature reaction processes, such as chemical distillation or high-temperature liquid injection processes.
4. Biocompatibility and Sanitary Design
   -Principle: Zirconia is non-toxic, with a surface finish of Ra ≤ 0.2 μ m, easy to clean, and does not adsorb microorganisms.
   -Data support: Certified by FDA (US Food and Drug Administration) and EU 10/2011 for food contact materials.
   -Problem solved: Meet the hygiene standards of the pharmaceutical and food industries and prevent cross contamination.
5. High precision and stability
   -Principle: Ceramic components have high dimensional stability and negligible deformation under high pressure (elastic modulus ≥ 200GPa).
   -Data support: Flow control accuracy error<± 0.5%, suitable for precision scenarios such as lithium battery electrolyte injection.
   -Problem solved: Improve production process consistency and reduce scrap rate.

Problem solved and economic benefits
Zirconia ceramic injection pump directly addresses the core challenges in industry through its performance advantages:
-Extend equipment lifespan: In corrosive environments, the lifespan of the pump body can be increased from 6-12 months for metal pumps to over 5 years, reducing replacement costs.
-Reduce pollution risks: In the semiconductor or pharmaceutical fields, avoid the precipitation of metal ions and ensure product purity (such as maintaining a resistivity of 18.2M Ω· cm for ultrapure water).
-Energy saving and consumption reducing: The low friction design reduces energy consumption by 15% -20% compared to traditional pumps (based on ISO 9905 energy efficiency testing).
-Maintenance cost optimization: Wear resistance reduces downtime, and annual maintenance costs decrease by 30% -50%.

Authoritative verification and industry recognition
The performance of zirconia ceramic injection pump has been verified by multiple international standards:
-Material testing: Complies with ISO 6474 (Ceramic Implants for Surgery) and ASTM F2393 (Ceramic Corrosion Resistance Standard).
-Industry application cases:
-In Tesla’s lithium battery production line, the zirconia injection pump controls the electrolyte filling error within 0.1%.
-BASF Chemical Group has adopted this pump as a replacement for Hastelloy pumps, reducing annual equipment costs by 40%.

Zirconia ceramic injection pump has become an ideal choice in the high-end fluid transmission field due to its characteristics of corrosion resistance, wear resistance, high temperature resistance, and high precision. It not only solves the reliability problem of traditional pump equipment in harsh environments, but also brings significant economic benefits through long-life and low maintenance design.
