Processing technology for improving strength of coal gangue hollow brick
The invention discloses a processing technology for improving the strength of a coal gangue hollow brick, and relates to the technical field of hollow bricks, and the processing technology specifically comprises the following steps: 1) putting tellurium powder and silicon powder into a high-temperature furnace, spin-coating a silicon dioxide/silicon substrate with a gold solution, putting the substrate at the downstream position of the high-temperature furnace, and carrying out high-temperature calcination to obtain modified silicon telluride particles; 2) crushing coal gangue, industrial waste soil, shell powder, ceramic powder, furnace slag, bentonite and granite tailings, injecting a water source, and conducting uniform mixing for later use; 3) adding the modified silicon telluride particles into the standby material, conducting uniform mixing, carrying out sealed aging, and conducting extruding through a brick extruder to obtain a molded hollow brick blank; and 4) sending the air-dried hollow brick blank into a sintering kiln for sintering to obtain the required high-strength coal gangue hollow brick. The hollow brick prepared by the invention has excellent mechanical properties, and is low in raw material cost, simple in process and suitable for large-scale production.
本发明公开了一种提高煤矸石空心砖强度的加工工艺，涉及空心砖技术领域，具体工艺如下：1）将碲粉和硅粉放入高温炉中，将金溶液旋涂到二氧化硅/硅衬底上，并将衬底放置在高温炉的下游位置处，经过高温煅烧得到改性碲化硅颗粒；2)将煤矸石、工业废土、贝壳粉、陶瓷粉末、炉渣、膨润土和花岗岩尾料粉碎后注入水源，混匀后备用；3)将改性碲化硅颗粒加入到备用的物料中，混匀后进行密封陈化，再通过挤砖机挤压出成型空心砖坯；4)将晾干的空心砖坯送入烧结窑中进行烧结，即可得到所需的高强度煤矸石空心砖。本发明制备的空心砖，具有优异的力学性能，并且原材料成本低，工艺简单，适用于大规模生产。
