FT-104E Fluorinated Aluminum Oxide Flow Angle Tester

FT-104EAluminum oxide flow angle tester

One Reference standard:GB-T-6609.31-2009 Chemical analysis methods and determination of physical properties of alumina - Part 31 Determination of flow angle; Replace AS2879.5-2004 "Determination of Flow Angle for Alumina Part";

II Scope of application:This section is applicable for determining the flow angle of alumina, with a measurement range of 30 ° -50 °

III definition:Angle of flow:

The angle formed between the conical surface formed by the sample and the bottom of the test bottle after it stops flowing in the test bottle. For ease of calculation, it is assumed that the vertebral body has a vertical lateral surface

4 Method principle:

Pour alumina into a flat bottomed container through a series of funnels. Allow the aluminum oxide leaked through the leak to flow out of the flat bottomed container, and calculate the flow angle based on the mass of the sample used to fill the container and the mass of the sample present in the container after the test

Five Parameter information:

1. Glass funnel: diameter 110mm ± 10mm, diameter of internal bottleneck 10mm ± 2mm

2. Stainless steel adjustable flow funnel: a smooth metal funnel with a diameter of 65mm ± 5mm; the diameter of the internal bottleneck is 5.5mm ± 0.5mm, and the length is 110mm ± 20mm. The length of the funnel bottleneck is 50mm ± 5mm, and the bottom of the bottleneck terminates in a square shape

3. Flat bottomed container: The inner diameter is 72.5mm ± 0.1mm, the inner height is 72.5mm ± 0.1mm, the diameter of the leak is 4mm ± 0.1mm, the thickness of the wall and root of the leak is 4.5mm ± 0.1mm, the theoretical volume of the container is 300mL, this container is made of aluminum, the inner wall is smooth, and the surface is flat

4. Hole plug: The size of the hole plug can tightly seal the bottom leak of the flat bottomed container

5. Plastic cup: with a capacity of approximately 400ml

6. The weighing scale should be provided by the customer themselves

7. Steel ruler, brush Overflow receiving tray
