0);">以下谈谈煤质活性炭主要指标的测定方法：<br /> 1、针对水分的试验测量方法<br /> 煤质活性炭的试验方法以水分的测定为基础，比较简单。采用试验科学严谨性原则，尽量蒸发试验样品中的水分，减去试验样品后样品的质量和实验前样品的质量，得到煤质颗?；钚蕴垦分兴值闹柿?，其主要过程是对一定量的煤质颗?；钚蕴渴匝椴牧辖懈稍锎?。得到煤质颗粒活性炭样品中水分的比例，完成水分的测定。煤质粒子活性炭试验的水分测定方法中，有水分充分蒸发的非常重要的注意事项。由于试验样品的水分不充分挥发，水分测定结果变小，样品中还会残留少量水分，因此进行比例研究时，水分质量小于实际值，从而影响试验结果。<br /> 2、碘吸附值试验的测定方法<br /> 煤质活性炭的主要性质是吸附性的，进行试验时一般使用碘进行吸附。试验方法也比较简单，将碘和煤质活性炭的试验样品按一定比例放入同一容器中，充分吸附后，用硫代硫酸钠测定碘的剩余浓度，从而将碘吸附的质量与初始质量进行比较，得出单个煤质颗?；钚蕴课父龅ノ坏钠渲校枰糠种邮褂枚傥迨握穸Ｖな匝檠泛偷獾某浞址从?，保证试验符合科学合理性原则。<br /> 3、强度的试验测量方法<br /> 煤质活性炭的强度对该物质来说是非常重要的性质，一般来说煤质活性炭是充分研磨煤炭，提高吸附能力得到的，所以他的强度和煤炭的硬度差不多，但必须比煤炭的强度稍好一些。在试验过程中，采用了比煤的强度大很多的材料，一般是钢球，测量煤质活性炭样品的强度，一方面保证试验过程不会损坏，降低了试验成本，高强度的试验材料磨损到煤质颗?；钚蕴垦飞?，选择试验材料后，需要进行试验。将钢球和煤炭粒子活性炭试验样品放在一起，进行旋转研磨，记录数据，测量煤炭粒子活性炭样品的强度。煤质颗?；钚蕴康氖匝榉椒ㄓ?0多种，试验者需要对影响试验结果的每一个因素进行充分的研究和分析，其中非常重要的项目是水分、碘吸附值和强度的测定，通过对其进行浅析，可以找出煤质活性炭试验的主要关键试验时，必须注意煤炭活性炭试验应遵守的基本原则。试验者通过对原则的掌握和方法的正确引用，保证整个煤炭活性炭试验顺利进行，取得科学的实验结果。<br
