GB 13173 ISO1064 Apparent Density Tester

标准:

  GB/T 13173-2009  ISO1064：1974 

standard: GB/T 13173-2009 ISO1064: 1974

原理：

在规定条件下，将试样从一个具有规定形状的漏斗中漏下，装满一个已知容积的受容器后，测定此粉体的质量。

principle: Under specified conditions, the sample is leaked from a funnel with a specified shape, and after filling a receiving container with a known volume, the quality of the powder is measured.

概述：

适用于自由流动的粉体,当使用合适的漏斗时,也适用于有结块趋势的粉体.若粉体中带有团块,则只有当这团块易于松散,且有不致使粉体的颗粒破碎的情况下,本设备才是适用的

Overview:

 It is suitable for free-flowing powders. When using a suitable funnel, it is also suitable for powders with a tendency to agglomerate. If there are clumps in the powder, only if the clumps are easy to loosen and do not cause the powder This equipment is suitable when the particles are broken

粉体的表观密度可用占有一定体积的粉体质量,或一定质量粉体所占的体积来评价。在这两种形式中,都包括把分内铜原容器转移到测量容器这一过程。由于产品易碎,其流动性或结块性,其粒子的几何形状的变化,加之测定时,由于倾注至测量容器而造成的不可避免的压缩,硬质一般所测得的表观不同于产品在原容器或包装中的密度.所以,测定的结果仅是一个与所用方法有关的惯用值.

The apparent density of powder can be evaluated by the mass of powder occupying a certain volume, or the volume occupied by a certain mass of powder. In both forms, the process of transferring the original copper container to the measuring container is included. Due to the fragility of the product, its fluidity or agglomeration, the change in the geometric shape of its particles, and the inevitable compression caused by pouring into the measuring container during the measurement, the appearance of the hardness is generally different from that of the product. The density in the original container or packaging. Therefore, the measured result is only a customary value related to the method used.

技术要求：

1、整体个漏斗材料为不锈钢制作,确保粉体所接触的表面是光滑的,且不允许产生静电

2、测定自由流动粉体时,漏斗下口径40mm,上口径108mm,高度130mm

3、测定有结块趋势的粉体时, 漏斗下口径60mm,上口径112mm,高度100mm

4、受料器容积：500ML±0.5ML,取样量：510-550ML

5、支架,能使漏斗和受料器对应定位

6、漏斗出口自带截止板/挡板,方便放置粉末

skills requirement:

1. The overall material of the funnel is made of stainless steel to ensure that the surface contacted by the powder is smooth and does not allow static electricity.

2. When measuring free-flowing powder, the lower diameter of the funnel is 40mm, the upper diameter is 108mm, and the height is 130mm.

3. When measuring powders with a tendency to agglomerate, the lower diameter of the funnel is 60mm, the upper diameter is 112mm, and the height is 100mm.

4. Volume of receiver: 500ML±0.5ML, sampling volume: 510-550ML

5. The bracket can position the funnel and the receiver correspondingly

6. The exit of the funnel comes with a cut-off plate/baffle for easy powder placement

测试步骤:

1. 将漏斗放到支架上面,称量过的容器放在下地板的位置。

2. 用截止板遮住漏斗的下口,将试样倒入漏斗,直至其上边缘,然后迅速移去截止板,让漏斗中的粉末随即流入收料器并完全溢出

3. 用不锈钢尺子沿着受料器的上口边缘,小心地粉体刮平,然后去称重m2.天平精度到0.01g

4. 根据计算公式密度=(M2-M1)/V算出粉体的表观密度
