Description
技术领域
本发明涉及建筑用砖技术领域,具体为莫来石隔热砖及其生产工艺。
背景技术
隔热砖是一种具有规则外形的隔热保温制品。属于轻质保温耐火材料。这类材料的共同特点是体积密度小,容重轻,导热系数低。但强度较低,高温重烧收缩较大,隔热、保湿效果好。
隔热性能优良,用于建筑物天面、内外墙面、坡顶建筑建基内外屋面的隔热保温工程。夏天能有效阻止太阳的热辐射,冬天能防止室内热量外传,改善顶层和建筑物室内的工作居住环境。使用建基隔热砖材料后,通常在盛夏炎热时,屋面内外表面温差最大达20℃以上,凡使用过该产品的用户都能感受到明显的隔热和节省空调电能的效果。该产品同时具有美化环境的装饰功效,表面洁净光亮,可拼装出不同图案色彩。由于楼面附有这种抗折抗压隔热防水性能优越的隔热保护层,楼板避免了因太阳暴晒而产生裂缝,可有效解决楼面隔热漏水等问题,建基隔热砖在这方面有了很大的突破,改善了这些问题所在。
目前隔热砖在生产的过程中需要消耗资源,不能利用废料进行加工使用,而在陶瓷产品的生产过程中,每一道的制备工艺都会产生废料,在经济飞速发展的背景下陶瓷产业也迅速壮大,从而导致陶瓷工业所产出的废料日益增多,并且浪费资源不利于陶瓷产业的循环发展,本申请文件采用将废料陶瓷破碎后融合其他物质进行生产莫来石隔热砖,由此提出了莫来石隔热砖及其生产工艺。
发明内容
针对现有技术的不足,本发明提供了莫来石隔热砖及其生产工艺,解决了目前隔热砖在生产的过程中需要消耗资源,不能利用废料进行加工使用,而在陶瓷产品的生产过程中,每一道的制备工艺都会产生废料,在经济飞速发展的背景下陶瓷产业也迅速壮大,从而导致陶瓷工业所产出的废料日益增多,并且浪费资源不利于陶瓷产业的循环发展,本申请文件采用将废料陶瓷破碎后融合其他物质进行生产莫来石隔热砖的问题。
