Dry state flocculation performance tester

Dry state flocculation performance tester

Applicable scope:

The dry state fluff tester, also known as the twist tester, is a specialized equipment used to evaluate the fluff shedding performance of non-woven fabrics under dry conditions. It is mainly suitable for evaluating the shedding performance of non-woven fabrics and other textile materials used in medical protective materials (surgical sheets, surgical gowns, clean clothes, etc.). When testing, the testing principle is that the sample is subjected to a combined effect of torsion and compression in the test chamber. During this twisting process, air is extracted from the test chamber and the test results are evaluated by counting and classifying the particles in the air using a laser dust particle counter.

Principle:

The sample undergoes a combined effect of torsion and compression in the test chamber. During this twisting process, air is extracted from the test chamber, and particles in the air are counted and classified using a laser dust particle counter.

Meets standards:

YY/T 0506.4, ISO 09073.10

1. Sealed torsion chamber and air mobile phone

2. Twisting speed: 60 times/minute

3. Twisting angle/stroke: 180 °/120mm

4. Sample fixture: 82.8mm

5. Laser particle counter testing range: Collect samples ranging from 0.3 to 25.0um

6. Laser particle counter flow rate: 28.3L/min, ± 5%

7. Sample testing data storage: 3000 pieces

8. Timer: 1-9999 times

Test environment:

Level 5 cleanroom (i.e. level 100 purification environment)

Main components

1. Dry state floc generator

1) Twisting device: a device that exerts a comprehensive effect on the specimen, including twisting, compression, and resetting

2) Twisted box (anti-static): An organic glass box that can resist static electricity and cover the twisting device for testing

3) Air collector: a sampling port with a certain shape fixed in a specific position in a twisted box

2. Laser dust particle counter

Count and classify the particles in the collected air
