MODERNER JTX-V automatic digitalization scrubber

product description

  JTX-V Scrub Tester (Multi-purpose Scrub Resistance, Stain Resistance, and Wet Scrub Resistance) is based on GB/T 9266 "Determination of Scrub Resistance of Architectural Coatings" and GB/T 9755 "Synthetic Resin Emulsion Exterior Wall Coatings" Standard appendix C requirements on scrubbing test, GB/T 9780 "Test method for stain resistance of architectural coatings" standard on stain resistance test requirements, GB/T 31410 "Paint and varnish coatings are scrub resistance and Cleanliness Evaluation" is designed and manufactured for the requirements of wet scrub resistance, and is used to evaluate the scrub resistance, stain resistance and wet scrub resistance of coatings. , overlay, wood density, etc.) properties. The device performs a scrubbing test on the paint painted on the standard test plate, and the scrubbing times can be controlled and read out by the touch screen. The scrub resistance of the coating is evaluated according to the number of times of scrubbing resistance, and the stain resistance and wet scrub resistance of the coating are evaluated according to the comparison before and after scrubbing.

Instructions for use

Scrub resistance test:

1. Soak the brush in 20°C water for 30 minutes in advance, the soaking depth is 12mm, then take out the brush and press it dry, and then soak it in 0.5% soap solution for 10 minutes.

2. Put the test plate in the working tray, and then clamp the test plate with the quick clamps on both sides, and the test plate must not have any serial movement during work.

3. Put the brush into the brush holder, tighten the fixing bolts to fix the brush from loosening, and then put it into the beam brush holder to confirm that the brush moves freely.

4. Put the water inlet pipe of the peristaltic pump into the scrubbing medium container.

5. Turn on the power and select the language.

6. The default interface is the washable interface, set the number of tests, select the test schedule and test frequency.

7. Turn on the automatic liquid filling switch during the scrubbing process, and the peristaltic pump will automatically drip into the scrubbing medium. If you need to wet first, you can click the manual mode. After the test plate is wet, turn off the manual mode.

8. Observe whether there is any wear and tear at the middle 10 cm of the test plate. If you want to stop halfway (not reaching the preset value), press the stop switch to stop washing. If you want to continue washing, just press the start switch.

9. When the test piece is not exposed to the bottom and the actual counting value has reached the predetermined value and the machine is shut down, if you want to continue the test, press the reset button and the counter will return to zero, otherwise it will not start, then press the start switch again, the counter will start counting again, and the accumulated washing times .

10. If it is used to test the product, just set the preset value to the qualified value, start the machine, and stop automatically when the predetermined value is reached, and check whether the test plate is exposed to judge whether the product is qualified.
Stain resistance test:

(1) Put the test plate in the work plate, and then clamp the test plate with the quick clamps on both sides, and the test plate must not have any serial movement during the work.

(2) Fix the gauze on the scrubbing jig, put it into the beam of the brush holder, and put a suitable counterweight on it.

(3) The following steps are the same as the previous "washing resistance test".
