What should be paid attention to during the use of zirconium plate?
The following matters need to be paid attention to during the use of zirconium plate:
Ambient temperature: The mechanical properties and corrosion resistance of zirconium and zirconium alloys decrease with increasing temperature. When the temperature is above 500℃, the corrosion resistance will be lost and the mechanical properties will also decrease. Therefore, zirconium plate can only be used in an environment below 500℃.
Gas contamination: Zirconium is an element with extremely active chemical properties and is easily contaminated by gases, especially in nitrogen and hydrogen atmospheres. At temperatures below 400-500℃, the reaction between zirconium and nitrogen is very weak; at 800-900℃, the reaction between zirconium and nitrogen is very strong, forming zirconium nitride; at 900-1000℃, zirconium can strongly absorb hydrogen to form ZrH₂, and it is very easy to produce hydrogen pores. Therefore, when storing, processing and using zirconium plates, avoid exposing them to atmospheres containing nitrogen and hydrogen.
Avoid scratches and collisions: The surface of the zirconium plate should be kept intact to avoid scratches, collisions and other damage, so as not to affect its corrosion resistance and appearance quality. During transportation and installation, use appropriate tools and methods to prevent damage to the surface of the plate.
Cleaning and maintenance: Clean the zirconium plate regularly to remove dirt, dust and impurities on the surface to maintain its good performance. Use appropriate cleaning agents and tools when cleaning, and avoid using substances that are corrosive to the zirconium plate.
Welding precautions: If it is necessary to weld the zirconium plate, choose the appropriate welding method and welding materials, and operate in strict accordance with the welding process requirements to ensure the welding quality. During the welding process, pay attention to the protection of the weld to prevent oxidation and contamination.
Contact with other materials: When the zirconium plate is in contact with other metals or materials, the electrochemical compatibility between them should be considered to avoid galvanic corrosion. If necessary, isolation measures can be taken or suitable intermediate materials can be used.
Processing technology: The processing of zirconium plates is difficult and requires appropriate processing technology and equipment. During the processing, pay attention to controlling the processing parameters to avoid excessive stress and deformation, which will affect the performance of the plate.
Quality inspection: Before using the zirconium plate, it should be quality inspected, including chemical composition, mechanical properties, corrosion resistance and other aspects, to ensure that the plate meets the use requirements.
Advantages of zirconium plate
Zirconium plate has the following advantages:
Excellent corrosion resistance: Zirconium plate shows amazing corrosion resistance in many corrosive media, and can resist the erosion of strong acids (such as hydrochloric acid, sulfuric acid, etc.), strong alkalis and salt solutions.
