3.Technical Parameter(Testing program) 3.1. Tap density DF-1001 multi-functional powder physical property tester provides the tap density determination method specified in American ASTM D6393-99 standard (Carl index) and national standard (measurement of metal powder tap density) GB/T 5162-2006 / ISO 3953:1993. The amplitudes 1-15 are arbitrarily adjustable. 3.2. Bulk Density The DF-1001 Multi-Function Powder Physical Property Tester provides three different standards for measurement: A) The method for determining the bulk density specified in the ASTM D6393-99 standard (Carl Index); B) National Standard GB 1479-2010 (metal powder bulk density - funnel method); C) Method for measuring bulk density specified in GB/T 16913.3-2008 (Determination of bulk density of natural packing method). 3.3 Angle of repose The DF-1001 Multi-Function Powder Physical Property Tester provides the measurement method specified in the American ASTM D6393-99 standard (Carl Index). 3.4 Collapse angle The HYL-1001 Multi-Function Powder Physical Property Tester provides the measurement method specified in the American ASTM D6393-99 standard (Carl Index). 3.5 Flat angle (scraper angle) The DF-1001 Multi-Function Powder Physical Property Tester provides the measurement method specified in the American ASTM D6393-99 standard (Carl Index). 3.6 Dispersion The DF-1001 Multi-Function Powder Physical Property Tester provides the measurement method specified in the American ASTM D6393-99 standard (Carl Index). 3.7 Hall flow meter DF-1001 multifunctional powder physical property tester is designed and manufactured according to the national standard GB 1482-84. This device is suitable for measuring the fluidity of metal powders by a standard funnel method. This device can be used for any powder that can flow freely through a standard funnel with a pore size of 2.5 mm. 3.8 Difference angle The difference between the angle of repose and the angle of collapse is called the difference angle. The larger the difference angle, the stronger the fluidity and jet flowability of the powder. 3.9 Compression The ratio of the difference between the tap density and the bulk density of the same sample to the tap density is the degree of compression. The degree of compression is also known as the compression ratio. The smaller the degree of compression, the better the fluidity of the powder. 3.10 Void ratio The void ratio refers to the percentage of voids in the powder as a percentage of the entire volume of the powder. The void ratio varies depending on factors such as the particle shape, the arrangement structure, and the particle diameter of the powder. When the particles are spherical, the powder void ratio is about 40%; when the particles are ultrafine or irregular, the powder void ratio is 70-80% or higher. 3.11 Agglutination degree The degree of agglutination is the amount of mutual cohesion exhibited by the surface of the powder particles. Generally, the dry powder has a small degree of agglutination. 3.12 Uniformity It is another form of expression of powder agglutination. When the powder cannot measure the degree of agglutination, the uniformity is used to indicate the amount of cohesive force of the powder. 3.13 Liquidity index The calculation of the liquidity index was determined by the British Carr in the 1960s. After measuring a large number of powders, he quantified the qualitative concept using a method similar to the integrated grading in fuzzy mathematics. Briefly, the fluidity index is a weighted sum of the term indices of angle of repose, compression, plate angle, uniformity, and agglutination. 3.14 Jet index It is an indicator to measure the difficulty of dust generation in powder materials, and is also a method to measure the difficulty of liquefaction of powders. The powder with strong jet flow is easy to generate dust and is also easily liquefied. The jet index is a physical index after the four indexes of fluidity index, collapse angle, difference angle and dispersion. 4.Packing List | Name | Model and Specification | Quantity | 1 | Host | DF—1001 | 1 | 2 | Instruction manual | DF—1001 | 1 | 3 | Angle of repose, crash angle sample table washer | Polyurethane | 4 | 4 | Measuring cylinder | 25ml | 1 | 50ml | 1 | 100ml | 2 | 5 | Damping pad (stainless steel Ф 12mm) | Thickness | 1mm | 1 | 2mm | 2 | 5mm | 2 | 6 | power cable | 250V 10A | 1 | 7 | fuse | 5 X 20mm,1A | 5 | 8 | brush | | 3 | 9 | Silicone pad | Ф70mmX2mm | 1 | 10 | Angle of repose sample table | stainless steel | 1 | 11 | Angle of repose funnel | stainless steel | 1 | 12 | Naturally stacked bulk density output funnel | stainless steel | 1 | 13 | Metal powder bulk density output funnel | stainless steel | 2 | 14 | Bulk density positioning table | stainless steel | 1 | 15 | Tap density vibration component | | 1 | 16 | Vibrating screen (one on the instrument) | | 4 | 17 | Overflow tray | stainless steel | 1 | 18 | Dispersion tray | | 1 | 19 | Blocking rod | stainless steel | 1 | 20 | Bulk density measuring cup (2 for 100ml, 1 for 25ml) | stainless steel | 3 | 21 | Heavy hammer | stainless steel | 1 | 22 | Sample spoon | stainless steel | 2 |
