Description

日用细瓷及其制备方法
技术领域
本发明涉及一种日用细瓷及其制备方法，属于无机非金属材料(陶瓷)领域。
背景技术
目前，日用细瓷长期以来一直是各国贵族用瓷，是目前世界上公认的高档瓷种。因其“薄如纸、透如镜、声如磬、白如玉”，瓷质细腻通透，器型美观典雅，彩面润泽光亮，花面多姿多彩的特点，成就了它洁白的质地和华贵的造型，兼有使用和艺术的双重价值，历史上是宫廷专用品和贵族收藏之珍品，是权力和地位的象征，号称“瓷器之王”。日用细瓷以其高质量、高格调、高品位成为各大星级宾馆、百货超市、豪富家庭的必选用瓷，更是馈赠亲友的最佳礼品。但日用细瓷与传统的高温瓷相比也有他的缺点，一是胎体硬度相对较差，产品长时期使用时瓷口容易生产缺口；二是热稳定性相对较差，骤冷骤热使用时，产品容易发生炸裂。因此研究发明一种具有日用细瓷优点，而且胎体硬度大、热稳定性好的日用细瓷就具有非常大的现实意义。
发明内容
本发明所要解决的技术问题是克服现有技术的缺陷，提供一种日用细瓷，它绿色低碳、产品硬度高、热稳定性能好。
为了解决以上技术问题，本发明的技术方案是：一种日用细瓷，它的原料的各组分及各组分质量百分比如下：
骨碳50～55％、高岭土20～30％、长石10～20％、石英5～15％，以上组分之和总计100％；然后在原料中外加原料总质量的5～10％的纳米纤维添加剂。
所述纳米纤维添加剂为硫酸钙纳米纤维。
本发明还提供了一种日用细瓷的制备方法，方法的步骤中含有：
按原料的各组分及各组分质量百分比依次经过精选、粉碎、配料、干粉球磨、添加纳米纤维添加剂、细度检测、调浆、放浆、过筛除铁、压滤榨泥、练泥、成型、干燥工序后，经8小时，素烧至1250℃，保温30min，冷却后即获得日用细瓷素胎。
进一步，干粉球磨工序的时间为18小时。
进一步，细度检测工序中，细度检测成型过250目筛，筛余为0.08％。
进一步，成型工序采用压制成型。
进一步，干燥工序的温度为45℃。
采用了上述技术方案后，本发明通过在原料中添加硫酸钙纳米纤维，利用其在坯体中形成的网状包裹结构，不仅可以增加坯体的可塑性和强度及胎体的白度和热稳定性能，解决了传统中低温日用细瓷的胎体硬度较差、热稳定性较差的缺点。并且其生产方法科学合理，工艺技术先进，易于实施，成品率高，产品质量好，并且能够大幅缩短了烧成周期、降低了烧成温度，显著降低了生产成本，因此具有广阔的市场前景。
具体实施方式
为了使本发明的内容更容易被清楚地理解，下面根据具体实施例，对本发明作进一步详细的说明。
