Lightweight porous ceramsite foamed by cooperation of electrolytic manganese residues and hydrogen peroxide and preparation method of lightweight porous ceramsite
The invention discloses a lightweight porous ceramsite foamed by electrolytic manganese residues and hydrogen peroxide and a preparation method thereof. The environment-friendly concrete is prepared from the following raw materials in parts by weight: 40 to 45 parts of electrolytic manganese residue, 18 to 20 parts of muck, 1 to 6 parts of hydrogen peroxide, 0.04 to 0.07 part of foam stabilizer, 0.2 to 0.5 part of coagulant and 30 to 32 parts of water. The MnO2 component in the electrolytic manganese residue is utilized to catalyze decomposition of hydrogen peroxide in hydrogen peroxide, O2 generated by reaction of the MnO2 component and the electrolytic manganese residue can provide enough pores for ceramsite so as to achieve the purpose of light weight and porosity, and a new direction is provided for resource utilization of the electrolytic manganese residue. The solid waste residue soil and the heavy metal pollutant electrolytic manganese residue are adopted as the gelling components to prepare the unfired light porous ceramsite, and the problems that the porous ceramsite is high in preparation cost, complex in process, unstable in product performance and the like are greatly solved.
本发明公开了一种电解锰渣协同双氧水发泡的轻质多孔陶粒及制备方法。本发明的按重量份计，包括如下原材料：电解锰渣：40‑45份，渣土：18‑20份，双氧水：1‑6份，稳泡剂：0.04‑0.07份，促凝剂：0.2‑0.5份，水：30‑32份。本发明利用电解锰渣中的MnO2组分催化双氧水中过氧化氢的分解，二者反应所产生的O2可为陶粒提供足够的气孔以达到轻质多孔的目的，为电解锰渣的资源化利用提供了一种新方向。而且本发明采用固体废弃物渣土以及重金属污染物电解锰渣作为胶凝组分制备免烧轻质多孔陶粒，大大解决了多孔陶粒制备成本高、工艺复杂、产品性能不稳定等问题。
