High Temperature Resistant 99.5% Al2O3 Alumina Ceramic Strips with Porous Holes
Key words : Alumina Ceramic Strips
Mingrui 's Alumina Ceramic Strip provides the ability to withstand higher temperatures (typically limited to 40 to 45 watts per square inch, depending on the application). The heater consists of a stainless steel sheath containing a high-temperature ceramic insulating a nickel chrome wire coil. Magnesium oxide (MgO) is used to fill any air pockets, thus providing the best heat transfer possible.
The terminals are also constructed of stainless steel and are securely anchored to prevent twisting out under normal conditions. Several terminations are available, including water-resistance.
High-quality Alumina Ceramic Strips (aluminum oxide Al2O3 99.9%, 99.7% and 96% and zirconia ZrO2) are present in low and high pressure injection valves. These components are equally vital in any other switching valve systems where inert materials resistant to the harshest solvents are required.
Mingrui manufactures high quality Alumina Ceramic Strips, made out of High Purity Alumina (97%, 99,7% or 99,9%) and TZP Zirconia ceramics for high and low pressure injection and selection valves. Rotors and Stators are subject to intensive mechanical stress and chemical aggression while having to maintain a perfectly leak free adjustment between the two components. No leak, limited stiction and low wear are the most important parameters to guarantee long life and reliability to your valve. These can be achieved by an adequate surface finish, a perfect flatness of the surfaces in contact and a proper selection of the material. Every application is different and Ceramaret will help you define the parameters required for your particular valve. Ceramic Rotors and Stators are used in valves for many high-tech applications, such as HPLC, micro-HPLC, Medical, Industrial, etc.

Advantages of Alumina Ceramic Strips:
1. Isostatic pressed.
2. Fire resistance.
3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. Zirconia and alumina ceramic material.
They are high corrosion and wear resistance and strong impact resistance and delivers 10 times longer working life than metal plunger. They give a longer life to the sealed packing material.
Our Ceramic Strip heaters provide a dependable, versatile and efficient heat source for a wide range of applications, such as:
They are available in many lengths. Whenever possible, please provide a dimensional sketch of your requirements with your order.
