High-whiteness porcelain blank and manufacturing method thereof
According to the high-whiteness porcelain blank and the manufacturing method thereof, the kaolin and the bentonite are mixed to prepare the premix, the premix is purified to remove heavy gravel and large-particle substances in the premix, the fineness of slurry is improved, and the content of iron and titanium in the slurry is reduced; and mixing the purified premix with quartz, talc, feldspar and industrial alumina powder, carrying out fine grinding to improve the compatibility among the components so as to prepare a basic blank, and carrying out impurity removal on the basic blank so as to prepare the high-whiteness porcelain blank. The high-whiteness porcelain blank prepared by the method provided by the invention is low in iron and titanium content, has good lubricity and plasticity, and has the advantages of high firing stability, good semi-finished product strength and good finished product transparency. In addition, the method also has the characteristic of high whiteness of a fired finished product.
本申请提供一种高白瓷坯料及其制作方法，通过将高岭土和膨润土混合制成预混料，将预混料通过提纯除去预混料中的重质沙石以及大颗粒物质，提升浆料的细腻度，并降低其中的铁、钛含量，再将提纯预混料与石英、滑石、长石和工业氧化铝粉混合，并进行细磨，提高各组分之间的相融性，制得基础坯料，将基础坯料进行除杂，从而制得高白瓷坯料。通过本申请的方法制得的高白瓷坯料，铁、钛含量低，具有良好的润滑性和可塑性，且具有烧成稳定性高、半成品强度佳、成品透明度好的优点。此外还具有烧成成品白度高的特点。
