Fiber Micro Diffal Tester

This instrument is designed and manufactured in accordance with the relevant requirements of "Appendix P Test Methods for High Temperature and Abrasion Resistance of Flocculent Mineral Fibers" in the transportation industry standard JT/T 533-2020 "Fibers for Asphalt Pavements". This instrument adopts the micro Diffal test tube method, collects the ground sample according to the specified temperature, steel tube speed and time, and uses the HW-SYD-XW1 fiber aeration sieve analyzer to screen and calculate to obtain the high temperature resistance of the sample, Test results of anti-wear performance.

Note: For the test in Appendix P, the SYD-XW1 fiber aeration sieve analyzer is also required to complete the high temperature resistance and abrasion resistance test of the flocculent mineral fiber together with this instrument.

Main technical features

1. It adopts color touch screen control, real-time display of test information, human-computer interaction, and convenient operation.

2. The rotating speed of the test tube is adjustable, and it can be set according to the needs of the test during use.

3. The test tube can be rotated according to the set number of rotations or rotation time, and it will stop automatically after the test is completed.

4. The instrument has its own safety protection device, which makes it safer for operators to use.

5. Silent cotton is installed inside the shield to reduce the noise during the test.

6. The test tube is made of high-quality 304 stainless steel, with excellent texture and easy cleaning.

7. It is driven by a servo motor, and the drive shaft and two supporting shafts are driven by a synchronous belt to drive the test tube to roll.

8. Two samples can be made at the same time in one test, and the test efficiency is high.
