Wet Abrasion Scrub Tester

The Wet Abrasion Scrub Tester is designed to evaluate the resistance of painted, coated, or uncoated surfaces to wet scrubbing and friction. It simulates cleaning, wear, and abrasion processes using brushes, sponges, scouring pads, or sandpaper, with optional cleaning agents or friction media. The instrument is widely used in coatings, construction, furniture, ceramic, and material research industries to ensure surface durability and quality.

Application

(1) Construction & Interior Finishes: Testing the scrub resistance of interior wall coatings, emulsion paints, varnishes, wallpapers, and ceramic or floor tiles.

(2) Furniture Manufacturing: Evaluating the durability of wood, composite board, and coated furniture surfaces against wet abrasion.

(3) Sanitary Ware & Ceramics: Assessing the resistance of bathtubs, sinks, and ceramic decorative items to repeated cleaning and surface wear.

(4) Automotive & Transportation: Testing automotive interiors, dashboards, and seat coatings for cleanability and wear resistance.

(5) Coatings & Surface Treatment R&D: Supporting formulation development for anti-stain, anti-wear, and protective coatings.

(6) Protective Films & Functional Layers: Evaluating the durability of protective films, optical films, and functional coatings.

(7) Quality Control & Production Monitoring: Ensuring consistent abrasion resistance and cleanability across production batches.

(8) Education & Research: Applied in material science research and teaching to study surface abrasion behavior.

Parameters

Accessories

(1) Three interchangeable scrub brushes or sponge pads

(2) Friction agent or cleaning agent reservoirs

(3) Pump assembly for wet scrubbing tests

(4) Power cable

(5) User manual and calibration guide

Test Procedures

(1) Install the desired brushes, sponges, or pads on the scrub test arm.

(2) Adjust stroke length, speed, and number of reciprocating cycles according to the test standard.

(3) Place the sample panel securely on the test platform.

(4) Add cleaning or friction agents if required.

(5) Start the machine and monitor the test via the touch screen.

(6) Record or print the test results after completion.

Maintenance Information

(1) Regularly check and lubricate the chain drive and moving parts.

(2) Inspect brushes or pads for wear and replace when necessary.

(3) Clean the pump and reservoirs after each test to prevent residue build-up.

(4) Calibrate stroke length and speed periodically for consistent performance.

(5) Ensure electrical components and display panel are free from moisture and dust.
