Coal gasification slag composite ceramsite and preparation method thereof
The invention belongs to the technical field of solid waste utilization, and provides coal gasification slag composite ceramsite and a preparation method thereof. The product is prepared from the following raw materials in parts by mass: 50-70 parts of coal gasification slag, 8-16 parts of red soil, 1-15 parts of oily sludge and 3-7 parts of auxiliaries. The coal gasification slag can reduce the density of the ceramsite, and after the coal gasification slag is mixed with the sodium hydroxide solution, the cylinder compressive strength of the ceramsite can be improved; the red clay can further improve the strength of the ceramsite; hydrocarbon substances in the oily sludge can react at high temperature to generate gas, and a gas cavity is formed; the bonding characteristic of the red soil and the oily sludge can promote the smooth proceeding of the granulation process; and the auxiliary agent can overcome the brittleness characteristic of the coal gasification slag. The ceramsite prepared by the invention has excellent comprehensive performance, meets the requirements of relevant national standards' Lightweight Aggregate (GB/T 17431.1-2010) ', and can be applied to the industries of building materials, gardening, fire-resistant and heat-insulating materials and the like.
本发明属于固废利用技术领域，提供了一种煤气化渣复合陶粒及其制备方法。该产品由包含下列质量份数的原料制备得到：煤气化渣50～70份、红土8～16份、含油污泥1～15份和助剂3～7份。煤气化渣可以降低陶粒的密度，将其与氢氧化钠溶液混合后，还能提高陶粒筒压强度；红土能进一步提高陶粒的强度；含油污泥中的烃类物质在高温下会反应生成气体，形成气体空腔；红土和含油污泥的粘结特性会促进造粒过程的顺利进行；助剂能克服煤气化渣本身较脆的特性。本发明制备得到的陶粒具有优异的综合性能，符合国家相关标准“轻集料(GB/T 17431.1‑2010)”的要求，可以在建筑建材、园艺和耐火保温材料等行业应用。
