glass sand

HSP series glass sand blasting machine automatic system is made of touch screen and PLC.

HSP系列玻璃喷砂机自动控制系统由触摸屏和可编程逻辑控制器（PLC）组成。

The experiments of measuring permeability are carried out with BZ-01 and BZ-02 glass sand as porous media. Methane hydrate is generated using constant volume method. And the permeability changes of porous media are tested under different saturation of methane hydrate with distilled water as the medium.

用BZ-01、BZ-02玻璃砂模拟多孔介质进行了渗透率测量实验，采用定容法合成甲烷水合物，以蒸馏水为介质测试了不同甲烷水合物饱和度下多孔介质渗透率的变化情况。
