传统的陶瓷卫生洁具是经过高温,一次烧制出来的。首次烧成的产品中有25％～60％的有缺陷,于是将它们处理一下再次烧成,其间原先产生的釉会失透。这样便会使产品的色泽变差,B_2O_3常用于防止玻璃失透,但是它还是没有用于原始釉料中。本文在卫生洁具釉中引入了B_2O_3,它将带来两点好处:提高了抗失透能力,再加热含B_2O_3的釉,其色泽不发生变化,由于一次烧成和二次烧成产品的外观相同,因此能显著提高高质釉的产量,釉的化学稳定性提高,且当经过清洁剂清洗后,其表面更加平滑。由于失透降低,化学稳定性提高,均使烧成后的釉面更光滑。所有这些优点使釉面更易于清洗,同时也能抑制细菌的滋生。B_2O_3用
Traditional ceramic sanitary ware is a high temperature, a firing out. First-baked products have 25% to 60% of defects, so they deal with once again firing, during which the original glaze will be devitrified. This will make the product color deterioration, B_2O_3 commonly used to prevent the glass from devitrification, but it is not used in the original glaze. In this paper, B_2O_3 is introduced into sanitary ware glaze, which will bring two advantages: anti-devitrification ability is improved, glaze containing B_2O_3 is heated, the color of B_2O_3 is not changed, the appearance of products due to primary firing and secondary firing The result is a significantly higher yield of high-quality glaze, improved chemical stability of the glaze, and a smoother surface when cleaned with detergent. As a result of reduced devitrification, increased chemical stability, the finished glaze is smoother. All of these advantages make the glaze easier to clean and at the same time inhibit the growth of bacteria. B_2O_3 use
