1.1 Medical field
The pharmaceutical industry has extremely high requirements for the purity and sealing of the drug production process. Zirconia ceramic plungers are used in pharmaceutical equipment, such as injection production equipment. Its high hardness and wear resistance enable the plunger to maintain dimensional accuracy during frequent reciprocating motion, ensuring a close fit with the pump body to prevent drug leakage and contamination. At the same time, it has good biocompatibility, will not react chemically with drugs, and will not release harmful substances into drugs, which is essential to ensure the quality and safety of drugs, especially when producing some high-value, purity-sensitive biopharmaceutical products.
The compatibility of ceramics with the human body has made it indispensable in the replacement of human teeth, bones, and joints. At the same time, because of the self-lubricating characteristics of the material, good surface density, easy polishing, and the presence of pure white color, it is also widely used in fine grinding medical parts such as plungers and seals.
1.2 Food and beverage field
In the processing and packaging of food and beverages, various liquids such as syrups, juices, and milk need to be transported. Zirconia ceramic plungers can be used as sealing components in food-grade equipment. Due to its stable chemical properties, it will not release harmful ingredients into food and meets food safety standards. In addition, it can effectively seal under high pressure to prevent liquid leakage, ensuring the efficiency and hygiene of food and beverage production and packaging processes. For example, in the canning production line of beverages, zirconia ceramic plungers can ensure that additives such as syrups are accurately injected into beverage bottles while maintaining the cleanliness of the production line and product quality.
1.3 Chemical Industry
Zirconia ceramic plungers are widely used in liquid delivery and metering systems in the chemical industry. Many chemical raw materials are corrosive, such as strong acid and strong alkali solutions. Zirconia ceramics have excellent corrosion resistance and can resist the erosion of these chemicals, ensuring that the plunger can still maintain good sealing when in long-term contact with corrosive liquids. For example, in the production process of pesticides, various chemical reagents need to be accurately delivered and metered. Zirconia ceramic plungers can effectively prevent reagent leakage and ensure the safety and accuracy of the production process.
