Abstract

本发明提供了一种处理废岩棉的方法。该方法将废岩棉通过挤压、剪切的方式制成颗粒状，而后再将这些颗粒与水泥或者石膏粉等胶结料进行干拌，和再让这些颗粒吸附一定量的水份以使这种颗粒的表面形成一层封闭膜。这种岩棉颗粒可以再作建筑材料使用。本发明解决了已往废岩棉难以利用从而丢弃所造成的占用大量场地，严重污染环境的问题。

Description

一种处理废岩棉的方法
本发明涉及废岩棉的处理方法。
岩棉制品是将岩石经高温熔化成岩浆、又经高速离心加工形成膨松的棉花状、而后再喷以酚醛树脂等胶结料定形而制成的一种工业产品。它是建筑工业中重要的建筑材料之一。岩棉制品被加工成各种尺寸规格的板材后会余下大量的边脚料，也即废岩棉，由于它们没有了什么利用价值，因而被人们废弃在一边，此举，不仅占用了大量的场地，而且还造成了严重的环境污染。
本发明的目的是提供一种处理废岩棉的方法，利用该方法人们可以将这些废岩棉再加以利用，一方面解决由于废岩棉被丢弃而造成的场地被大量占用和环境污染的问题，另一面还可变废为宝，进一步提高经济效益。
本发明所说的方法是这样的。使用通用的螺旋挤压剪切机，所说的该剪切机其结构其实类似铰肉机，它里面带螺杆、孔板和切刀。将所说的废岩棉放入到螺旋挤压剪切机内，在螺杆的挤压下，废岩棉从孔板中被挤出并被剪切成颗粒状，接着，将这些颗粒与水泥或者石膏粉等胶结料进行干扮，然后，再让这些颗粒吸附一定量的水份以使这些颗粒的表面形成一层封闭膜，做成岩棉颗粒。这些岩棉颗粒可以作多种建材料使用，如混以水泥、沙、经挤压成型后可作轻质墙砖或者屋面隔热板，混以石膏等胶结料挤压成型后可做天花板等。
本发明提供的加工废岩棉的方法，可以把废岩棉加工成有用的建筑材料，它不但可解决废岩棉被废弃占用大量场地、严重污染环境的问题，而且它还可进一步地提高企业的经济效益。另外，该方法也简单、投资省、方便推广。
