3D printing quartz sand preparation process
The invention discloses a 3D printing quartz sand preparation process, belongs to the technical field of photocuring 3D printing, and aims to solve the problem that existing 3D printing quartz sand is poor in performance. The 3D printing quartz sand is composed of natural quartz sand, nano cristobalite powder and fused quartz powder. After the natural quartz sand is cleaned and deslimed, the mud content of the natural quartz sand is greatly reduced, and then natural quartz sand with an appropriate particle size proportion is obtained after multiple times of ball milling, screening and mixing. Part of components in the natural quartz sand can play a role in assisting melting in the sintering process to reduce the temperature of a ceramic sintering liquid phase and widen the ceramic sintering temperature range. Heating of the nano cristobalite powder can effectively improve the final sintering temperature and the high-temperature thermal deformation resistance of quartz ceramic. The nano effect of the nano cristobalite can effectively increase the strength of the ceramic at room temperature. The dispersity of quartz sand powder in resin can be improved by pouring the mixed quartz powder into boiling water and carrying out boiling water bath for 30 minutes. The method is suitable for preparing 3D printing quartz sand.
本发明公开了一种3D打印石英砂制备工艺，属于光固化3D打印技术领域，目的在于解决现有3D打印石英砂性能较差的问题。其通过天然石英砂、纳米方石英粉、熔融石英粉组成，天然石英砂清洗脱泥后，大大降低其含泥量，再经过多次球磨、筛分、混合后得到适宜粒径大小比例的天然石英砂。天然石英砂中的部分成分可以在烧结过程中起到助融作用，降低陶瓷烧结液相出现的温度，增加陶瓷烧结温度范围，纳米方石英粉的加热可有效提高终烧温度和石英陶瓷抗高温热变形能力，纳米方石英的纳米效应可有效增加陶瓷室温强度，将混合后的石英粉倒入沸水中，沸水浴30分钟，可改善石英砂粉体在树脂中的分散性。本发明适用于3D打印石英砂制备。
