Description

一种电梯井道上梁结构用的粉煤灰
技术领域
本发明涉及一种粉煤灰，特别是一种制造电梯井道上梁的粉煤灰，属于电梯制造领域。
背景技术
粉煤灰，是从煤燃烧后的烟气中收捕下来的细灰，粉煤灰是燃煤电厂排出的主要固体废物。我国火电厂粉煤灰的主要氧化物组成有些为：SiO2、Al2O3、FeO、Fe2O3、CaO、TiO2等。随着电力工业的发展，燃煤电厂的粉煤灰排放量逐年增加，成为我国当前排量较大的工业废渣之一。大量的粉煤灰不加处理，就会产生扬尘，污染大气；若排入水系会造成河流淤塞，而其中的有毒化学物质还会对人体和生物造成危害。因此，申请人经过反复试验，将粉煤灰与水泥、矿渣、砂等材料进行混合制造生成电梯井道上梁，但是因为常规的粉煤灰配比较不合理，导致产品的强度和使用寿命并不理想。
发明内容
本发明的目的在于，提供一种电梯井道上梁结构用的粉煤灰。本发明显著提高了产品的力学性能，解决了安全隐患，同时也提高了使用寿命。
本发明的技术方案：一种电梯井道上梁结构用的粉煤灰，按重量份包括二氧化硅粉未50-100份、氧化钙粉未5-15份、电石渣5-15份、三氧化二铝粉未30-60份、三氧化二铁粉未5-15份、氧化镁粉未2-8份、三氧化硫粉未1-3份。
上述的电梯井道上梁结构用的粉煤灰中，所述的粉煤灰按重量份包括二氧化硅粉未72份、氧化钙粉未10份、电石渣10份、三氧化二铝粉未40份、三氧化二铁粉未8份、氧化镁粉未5份、三氧化硫粉未1.5份。
与现有技术相比，本发明对电梯井道上梁结构用的粉煤灰进行了优选，与常规的粉煤灰相比，本发明制得的混石土电梯上梁具有更好的承重性能，经试验该加强筋从1米高度处颠落无明显开裂现象，经试验，本发明制得的上梁的强度可达到C30的标注，静耐载压力4500kg，经模拟测试十年后强度大于原设计强度的90％，效果非常明显。
