型号：ZK660931

 

标准:

GB/T-6609.31-2009 Chemical analysis methods ａnd determination of physical performance of alumina - Part 31: Determination of angle of flo

 

适用范围:

本部分适用于氧化铝流动角测定，测定范围：30°-50°.

 

流动角：

试料在测试瓶中停止流动后，试料形成的椎形面与测试瓶底间形成的角度。

 

原理：

将氧化铝通过一系列漏斗倒入平底容器中。允许通过漏口下漏的氧化铝流出平底容器，根据用于填充容器的试料质量和试验后容器内存在试料的质量计算流动角度.

 

技术参数:

1.漏斗：直径为110mm±10mm，内部瓶颈的直径为10mm±2mm

2.不锈钢可调节流速漏斗：壁内光滑的金属漏斗，直径为65mm±5mm；内部瓶颈的直径为5.5mm±0.5mm，长度为110mm±20mm。漏斗瓶颈的长度为50mm±5mm，瓶颈底部终止处为正方形.

3.平底容器：内径为72.5mm±0.1mm，内高为72.5mm±0.1mm，漏口的直径是4mm±0.1mm，漏口的壁和根部的厚度为4.5mm±0.1mm，容器的理论容积为300mL，此容器为铝质，内壁光滑，表面平坦.

4.孔塞：孔塞的尺寸能够塞紧平底容器底部漏口

5.塑料杯：容积约为400ml

6.称重天平客户自备

7.钢尺,毛刷.溢出接料盘.
