Burning-free technology of ecological stone for road
The invention discloses a non-burning process of ecological stone for roads, which comprises ten process steps of raw material crushing, raw material mixing, injection molding, compression molding, demolding, steam curing, drying, coating, cooling and polishing. The preparation method comprises the following specific steps: S1, crushing raw materials: pouring slag, ore tailings, coal ash and waste ceramic tile slag for producing the ecological stone for the road into a crusher, and crushing into the raw materials meeting the particle size requirement; the ecological stone for the road is prepared in a mode of replacing kiln sintering with steam curing, harmful substances generated by chemical reaction caused by high-temperature sintering are avoided, emission of sulfur, nitrogen and dust is reduced, meanwhile, the condensation effect between the raw materials of the ecological stone for the road is good, the surface of the ecological stone for the road is more attractive, and the service life of the ecological stone is prolonged. And protection is formed to prevent the surface of the ecological stone for the road from being directly rubbed to generate disintegrating slag, and meanwhile, the residual quantity of harmful substances is reduced by adopting a physical means.
本发明公开了一种道路用生态石免烧工艺,包括原料粉碎——原料混合——注模——压制成型——脱模——蒸汽养护——干燥——镀膜——冷却——抛光十个工艺步骤,具体步骤如下:S1原料粉碎:将用于生产道路用生态石的矿渣、矿石尾料、煤灰、废瓷砖渣倒入粉碎机中,粉碎成符合粒径要求的原料;本发明采用蒸汽养护代替窑炉烧结的方式制备道路用生态石,避免了因高温烧结发生化学反应而产生有害物质,降低了硫氮尘的排放,同时道路用生态石原料之间的凝结效果好,道路用生态石的表面更加美观,形成防护避免道路用生态石表面直接受到摩擦后产生碎渣,同时采用物理手段降低了有害物质的残留量。
