超级低气孔砖
技术领域
本发明涉及一种耐火砖,尤其涉及一种超级低气孔砖。
背景技术
玻璃窑,是玻璃制造中用于熔制玻璃配合料的热工设备。玻璃窑与其他窑不同,其对显气孔率要求更高否则,将严重影响玻璃制品的质量,例如结石、气泡、波筋等缺陷。耐火砖的气孔率直接影响到耐火砖的性能的各项指标,所以降低气孔率成为目前耐火砖生产企业亟待解决的首要问题。

为解决上述技术问题,本发明提供了一种超级低气孔砖,具体而言通过以下技术方案实现:
本发明所述的一种超级低气孔砖,含有以重量份为单位的下列各原料,焦宝石大颗粒10~20份,焦宝石细颗粒40~45份,硅线石小颗粒5~10份,莫来石细粉3-5份,铝矾土细粉0-5份,结合剂8~10份,外加剂8~10份;所述焦宝石大颗粒、焦宝石细颗粒无铁焦宝石颗粒。
优先的,所述焦宝石大颗粒20份,焦宝石细颗粒45份,硅线石小颗粒10 份,莫来石细粉5份,铝矾土细粉5份,外加剂10份,结合剂10份。
优先的,所述焦宝石大颗粒30份,焦宝石细颗粒40份,硅线石小颗粒6 份,莫来石细粉3份,铝矾土细粉3份,外加剂8份,结合剂8份。
优先的,所述焦宝石大颗粒30份颗粒度为3mm-0,焦宝石细颗粒40份颗粒度≤0.08mm,莫来石细粉3份≤0.076mm,铝矾土细粉5份≤0.088mm。
优先的,所述外加剂为纸浆水。
优先的,所述结合剂为高铝泥。
本发明的有益效果:本发明以焦宝石为主料,保持现在市面上耐火砖的性能,并通过调整莫来石细粉颗粒度,并通过增设铝矾土细粉来改变组成耐火砖原料的配制。使制品的高温使用性能得到显著提高,解决了降低气孔率这一关键技术,显著降低了气孔率。
具体实施方式
本发明所述的本发明所述的一种超级低气孔砖,含有以重量份为单位的下列各原料,焦宝石大颗粒10~20份,焦宝石细颗粒40~45份,硅线石小颗粒5~ 10份,莫来石细粉3-5份,铝矾土细粉0-5份,结合剂8~10份,外加剂8~10 份;所述焦宝石大颗粒、焦宝石细颗粒无铁焦宝石颗粒。所述焦宝石大颗粒30 份颗粒度为3mm-0,焦宝石细颗粒40份颗粒度≤0.08mm,莫来石细粉3份≤ 0.076mm,铝矾土细粉5份≤0.088mm。优先的,所述外加剂为纸浆水。所述结合剂为高铝泥。所述纸浆水、高铝泥为现有技术在此不再赘述。

Figure RE-GDA0002402939160000021
实施例1,所述焦宝石大颗粒20份,焦宝石细颗粒45份,硅线石小颗粒 10份,莫来石细粉5份,铝矾土细粉5份,外加剂10份,结合剂10份。
实施例2,所述焦宝石大颗粒30份,焦宝石细颗粒40份,硅线石小颗粒6 份,莫来石细粉3份,铝矾土细粉3份,外加剂8份,结合剂8份。
上述两实施例的实施例1,实施例2所述超级低气孔砖理化指标如表2所示:
Figure RE-GDA0002402939160000031
总上所述,通过多次人工挑出密度高、纯度高、磁化好的焦宝石,然后加工成符合工艺要求的各种粒度和粉剂,再通过高强电磁除铁器除铁,由全自动精密的电子配料,通过强力混碾、高压成型、高温烧成而成,并通过莫来石细粉、铝矾土细粉进行改性。荷重软化温度大于1500℃,远高于一般低气孔黏土砖,体积密度大显气孔率低,并且铁”即铁的含量低,不会产生任何有害物质,也不会污染玻璃,使玻璃更洁净更纯真。
最后说明的是,以上实施例仅用以说明本发明的技术方案而非限制,尽管参照较佳实施例对本发明进行了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或者等同替换,而不脱离本发明技术方案的宗旨和范围,其均应涵盖在本发明的权利要求范围当中。
