Abstract

一种切割混合气，是由液化石油气添加浓度为99.5%的甲醇而成，用于金属切割，成本低，工艺简单而且切割效果好，无污染。

Description

切割混合气
本发明涉及燃气气体，特别适用于金属切割用混合气体。
目前金属切割用乙炔，切割时废渣多，被切工件表面光洁度差，而且乙炔提炼成本高，环境污染严重。
本发明的目的是克服上述缺陷，提供一种混合气体替代乙炔用于切割金属。
本发明的方案是这样的：用丙烷钢瓶充装10公斤液化石油气，添加浓度为99.5％的甲醇20毫升。
本发明的优点在于节约能源，无污染，成本低，而且切割时工件上缘不易烧塌，下缘不易挂渣，切割精度高。
本发明是这样实施的，用丙烷钢瓶充装10公斤液化石油气时添加浓度为99.5％的甲醇20毫升，生产充装设备，工艺流程与现有民用液化气充装类同。使用时只需将气割枪与钢瓶用软管连接好，就可按常规进行金属切割。
其化学反应式为：
