Fiber Micro Defal Tester

This instrumentFiber Micro Defal TesterAccording to transportation industry standardsAppendix P of JT/T 533-2020 "Fibers for Asphalt Pavement"Test method for high temperature resistance and abrasion resistance of flocculent mineral fibers”The relevant requirements are designed and manufactured.

Fiber Micro Defal TesterAdopting a miniature Difal test tube squareAccording to the specified temperature, steel cylinder speed, and time, collect the ground sample and use itScreening and calculation of SYD-XW1 fiber impact gas sieve analyzer to obtain test results of high temperature resistance and wear resistance of the sample.

Note: AppendixThe experiment of P also requires the use of SYD-XW1 fiber jet sieve analyzer, which should be completed together with this instrumentHigh temperature resistance and abrasion resistance test of flocculent mineral fibers.

1、 Main technical features

1. Adopting color touch screen control, real-time display of experimental information, human-computer interaction, and convenient operation.

2. The rotational speed of the test tube can be adjusted and set according to the needs of the test during use.

3. The test tube can rotate according to the set number of rotations or rotation time, and automatically stops after completing the test.

4. The instrument comes with a safety protection device, making it safer for operators to use.

5. Install silent cotton inside the shield to reduce noise during testing.
