煤分析
Reply #42019-04-18
求助下海川网友,我是做煤分析的。昨天朋友拿来了一制好的煤样品,我正常分析称内水。称挥发份时候称一次天平结果变一次《小数点后第三位变化。基本都有 d位数的变化。煤烧好后,变化较小,有 d位数的变化》?我的天平是正常的,也校正了。我把以前我做煤的样品拿来称,也是正常的。请问下群友这是什么煤?有好的称量方法吗?

运这个与什么煤没有直接的关系!看问题应该是制备的煤样条件可能与你不同。主要还有你环境湿度过大!称量速度要快!个人认为没有必要改变称量方法!

谢谢!我把我以前做过的煤样品,拿来秤就没这种现象。我也换了台天平秤也是出现同样问题。这是什么问题?

既然是煤样品,在常温下称量只有水分的蒸发或吸收造成主要的影响!

你好!我的地理坐标在凉山州【就是在木里火灾附近】环境很干燥的。称量速度是正常速度,以前是怎么称的现在也是怎么称。我不太懂的是我以前做过的煤样品,拿来秤就没这种现象。我也换了台天平秤也是出现同样问题。我想知道是煤的原因吗?同行的遇到过这样的问题吗?
