X-ray porosity analyzerIt is a non-destructive testing equipment based on X-ray imaging technology, which analyzes the absorption characteristics of materials to X-rays, accurately quantifies the internal pore structure, and is widely used in quality control and scientific research analysis in fields such as glass ceramics, metal materials, composite materials, and geological rock cores. The equipment uses a microfocus X-ray source to emit high-energy radiation, which penetrates the sample and is then attenuated by a high-resolution detector. There are differences in the absorption of X-rays by materials with different densities. The lower density in the pore area leads to an increase in the transmitted radiation intensity. The system calculates the attenuation coefficient of each area and generates a high-resolution digital model using a three-dimensional reconstruction algorithm to visually present the size, shape, distribution, and connectivity of the pores. For example, in glass container inspection, small holes with a diameter of 0.1mm or more can be clearly identified.
X-ray porosity analyzerThe main maintenance points are:
1、 Daily maintenance
1. Environmental control
Temperature and humidity: Maintain a constant temperature in the laboratory (usually 20-25 ° C) and a relative humidity of 40-60% to avoid condensation and static electricity.
Cleanliness: Prevent dust from entering the interior of the equipment, especially in the X-ray source window, detector, and sample stage areas.
Shock resistant: Installed on a stable and vibration free platform, away from large machinery or high-frequency vibration sources.
2. Power on/off specifications
Start/shut down the system in accordance with the manufacturer's operating manual to avoid sudden power outages.
Preheat the X-ray tube after startup (usually 10-30 minutes) to ensure stable output.
3. Sample management
Clean the surface of the sample to avoid oil and dust contamination of the sample stage or optical path.
Do not place samples that exceed size, weight, or density limits to prevent damage to the rotating table or obstruction of radiation.
2、 Regular maintenance (recommended to be carried out monthly/quarterly)
1. X-ray source maintenance
Check the working status of the X-ray tube (current, voltage stability, output intensity).
Monitor the lifespan of the anode target material to avoid overloading and causing "ignition" or vacuum failure.
Regularly conduct insulation checks on high-voltage cables and interfaces.
2. Detector maintenance
Clean the detector window (using a dust-free cloth and anhydrous ethanol, gently operate).
Check if the cooling system of the detector (such as Peltier or water cooling) is working properly to prevent overheating noise from increasing.
Calibration detector response consistency (can be verified through standard reference samples).
3. Mechanical system inspection
Check the motion accuracy and lubrication status of the sample rotary table and translation table.
Calibrate the Center of Rotation (COR) to ensure that the reconstructed image is free of artifacts.
Tighten screws and guide rails to prevent mechanical looseness from affecting resolution.
4. Software and Data Systems
Regularly backup system parameters, calibration files, and user data.
Update drivers and analysis software (pay attention to compatibility).
Clean up computer cache to prevent image reconstruction from lagging or failing.
