Description

一种水磨石废浆利用方法
本发明涉及一种水磨石板磨制过程中产生的废浆利用方法。
水磨石废浆混合物是水磨石板磨制过程中产生的，它的数量大，每生产一平方米水磨石板，就产生废浆混合物0.4m3，这种废浆混合物含有微量汞、铅、镉等多种有害物，它能导致土地碱化，农作物有害金属蓄积，能否处理好水磨石废浆混合物，是众多厂家迫切解决的问题，过去，人们一般采用两种形式，一是将废浆混合物直接排向溪沟、河流，造成环境污染；二是把废浆混合物排入修建的沉淀池，沉淀后，废水排出，剩余的废浆用车运输抛至野外，同样造成环境污染，同时增加运输费用和征地费。
本发明的目的是提供一种水磨石废浆利用方法，采取此力法，将废浆与水泥、沙石、水混合制成非承重水泥制品，比如城市人行道板、屋面隔热板，从而达到废物利用，避免因排放造成的环境污染。
本发明采用的方案是：将排入沉淀池的废浆混合物沉淀后，排去废水，剩余的废浆自然凉干，凉干的废浆就可以取代一部分沙石，再将它与水泥、沙石、水混合拌匀，倒入带钢筋骨架模具内，按普通水泥制品的方法制造。值得注意的是，掺入凉干的废浆与沙石的比值最大不能超过3.5∶6.5，因为过多掺入废浆，影响水泥制品的强度和粘接度，易损坏，根据实践证明，最佳值是2∶8～2.5∶7.5，这种配比，既保证了水泥制品的质量，又加快了废浆消耗。其次，该水泥制品不能用作承载较重的物质。
采用本方法，避免了因排放废浆混合物造成的环境污染，同时，废物利用，可制成非承重水泥制品，该方法工艺简单，实用性强，社会经济效益好。
实施例：
将废浆混合物排入沉淀池，排走上面的废水，剩余废浆自然凉干，再将凉干的废浆与水泥、沙石、水混合拌匀，倒入带钢筋骨架的模具内，加振、压实形成后按一般水泥制品养护，凉干废浆与沙石的比值2.2∶7.8。
