技术领域
本发明属于陶瓷岩板技术领域,特别涉及一种具有透光性能的耐热陶瓷岩板产品、耐热陶瓷岩板产品制造方法及其废玻璃清洁再利用系统处理方法。
背景技术
现有透光砖(板)一般采用降低配方中的铝含量来增加玻璃相,或以高石英质,或以“钾钠”、“高钙、钠”形成折射率较低的钙长石晶相来实现透光效果,均是通过增加玻璃相和溶剂性原料降低粘土的用量和添加白云石的方式引入Na2O和CaO来实现透光效果,但这些透光砖(板)的透光率较低,且产品脆性较大,耐热性能不佳,尤其是后期进行水刀或桥切等切割加工时容易产生炸裂、崩边和崩角缺陷。
例如CN101898891B所公开的一种半透光性陶瓷材料、陶瓷薄板及其制备方法,CN201911182617.9所公开的一种定位晶花透光陶瓷砖及其制备方法,两个技术方案均是采用“钾钠”配方体系,所形成的产品虽然具有透光性能,但是耐热性能不佳,产品脆性大,后期加工成活率低。

⑵清洗干净后的锂铝硅废玻璃经4目过筛,粒径小于4目的直接收集到吨袋滴水晾干,粒径大于4目的输送至破碎设备中进行破碎,再过4目筛吨袋收集,滴水自然晾干,保证锂铝硅废玻璃粉的清洁度好、粒径均匀。
与现有技术相比,本发明的有益效果:
⑴本发明所采用的岩晶石为大自然花岗岩开采的尾料,其在配方的其他原料多元成分共熔作用下,增强了一致熔融性,进而使产品得到较高的白度。

⑶根据本发明方法所制得的产品,具有透光性强,抗热震性能良好的特点,产品热膨胀系数低,耐热性能佳,可以随意进行二次加工。
