Iron oxide red is stable in the atmosphere and sunlight, resistant to polluted gases, high temperatures, and alkalis. It is often used to color bricks and paint walls. However, sometimes uneven colors may appear. But sometimes there may be uneven coloring, how should we deal with this situation?
1. We need to strengthen the quality control of raw materials, especially the control of sand and gravel mud content. Through practical comparison, selecting the appropriate concrete mix proportion while meeting the requirements of sand and gravel grading and concrete workability can prolong the mixing and vibration time of raw materials as much as possible.
2. Regularly maintain and prepare equipment, calibrate measuring equipment, reduce measurement errors, and ensure that the measurement standards for pigments and cement are close to a stable state.
3. Different batches of iron oxide red pigment will have different pigment colors. Suitable pigments need to be selected according to the requirements of building bricks, ensuring consistent color while maintaining stable quality and minimal color difference.
Therefore, when using iron oxide red, workers must strictly control the construction environment conditions, follow the preparation standards, and follow the required standards in all aspects to avoid uneven coloring caused by external factors to a greater extent.
The above are the problems that may occur when coloring bricks with iron oxide red, which can be used as a reference when using it. It has a wide range of applications, and it is still necessary to follow the standard operation when using it to avoid accidents caused by improper operation.
