Preparation method of composite titanium extraction tailing-based calcium silicate board and calcium silicate board
The invention relates to a preparation method of a composite titanium extraction tailing-based calcium silicate board and the calcium silicate board. The preparation method specifically comprises the following steps: obtaining composite titanium extraction tailings, Portland cement, a siliceous raw material, a calcium raw material and wood fibers; the obtained raw materials are subjected to wet mixing, the ratio of liquid to the raw materials is controlled to be 0.5-0.8, the wet mixing time is controlled to be 5-15 min, and slurry is obtained; preparing the obtained slurry into a wet blank by adopting a flow slurry forming process; the wet blank is placed in a shady place to be cured for 6-36 h at the normal temperature, and a sample blank is obtained; the sample blank is put into a cement autoclave for autoclaved curing, the autoclaved curing temperature is controlled to be 120-200 DEG C, the autoclaved curing time is controlled to be 4-12 h, and the composite titanium extraction tailing-based calcium silicate board is obtained. The using amount of the composite titanium extraction tailings is higher than 40%, the problem that a large amount of titanium extraction tailings are piled up can be solved, meanwhile, the raw material cost can be remarkably reduced, and the enterprise profit can be increased.
本发明涉及一种复合提钛尾渣基硅酸钙板的制备方法及硅酸钙板，具体包括：获取复合提钛尾渣、硅酸盐水泥、硅质原料、钙质原料和木纤维；将获取到的原料进行湿混，控制液体与原料的配比为0.5～0.8，控制湿混时间为5～15min，得到料浆；将获取到的料浆采用流浆成型工艺制成湿坯；将湿坯放置于背阴处常温养护6～36h，获取样坯；将样坯放入水泥压蒸釜中蒸压养护，控制蒸压养护温度为120～200℃，控制蒸压养护时间为4～12h，得到复合提钛尾渣基硅酸钙板。本发明中复合提钛尾渣用量高于40％，不仅能够解决提钛尾渣大量堆存问题，同时可显著降低原料成本，提高企业利润。
