Zirocnia Ceramics:
Zirconia Whiteness: The reflectance of a white or nearly white paper surface to blue light, expressed as a percentage relative to the reflectance of a standard magnesia plate. Opacity: expressed as a percentage ratio of the reflectivity of a single sample on a "totally absorbing" black liner to the reflectivity of several samples that are completely opaque. Our Zirconia Ceramic Standard Parts are specifically designed to withstand the rigors of daily operations, ensuring that your machine runs smoothly and efficiently. With our Zirconia Ceramic Parts and Bars, you can rest assured that your milling machine is equipped with the best components for long-term reliability.
Transparency: The degree to which light penetrates through the paper. It is expressed by the maximum number of layers that the sample can see the ink lines clearly. Optical performance indicators are more important for printing paper and tracing. ① Moisture: The weight of water that can be evaporated in the paper at 100～105℃ is expressed as a percentage to the weight of the paper. Ash content: expressed as a percentage of the weight of the residue after burning of the paper to the weight of the absolute dry sample of the paper. pH value: The pH value of the water extract after the paper sample is soaked in distilled water at 95-100°C for 1 hour. These chemical properties are particularly important for electrical and technical papers. Zirconia surface properties Sizing degree (water resistance): the performance of the paper surface to prevent the penetration and diffusion of ink during writing, which is very important for writing paper. Use a duckbill pen dipped in special ink to draw a line on the paper, expressed as the maximum width (mm) of the non-diffusion and non-penetrating line. Smoothness: Under a certain degree of vacuum, the time required for a certain volume of air to pass through the gap between the sample surface and the glass surface under a certain pressure, expressed in seconds.
