First, mortar self-leveling wear testing machine

Principle

Reference to this instrument

GB 1768

When the surface of the product is rubbed against the sanding wheel to a specified number of revolutions, the amount of wear on the surface of the product is measured.

Second, mortar self-leveling wear testing machine

Test piece preparation

Pour the prepared sample into the wear-resistant test mold without vibration.

24h

After demolding, continue to place under standard conditions

27d

After the measurement.

Third, mortar self-leveling wear testing machine

Grinding wheel production

a)

Will be brown corundum

P60

Dry matte cloth cut with rubber wheel thickness specifications;

b)

Applying the cut abrasive cloth to the rubber wheel with a polyvinyl acetate emulsion, and directly bonding if it is a self-adhesive abrasive cloth;

c)

Ensure that the joints of the abrasive cloth should not overlap or sew, and each abrasive cloth can only be used once. The replacement of the test pieces must be replaced;

d)

Place the grinding wheel after the abrasive cloth is placed under standard test conditions for 24 hours above spare.

Fourth, mortar self-leveling wear testing machine

Experiment procedure

a)

Wipe the surface of the test piece with a gauze and weigh it to the nearest 10mg.

b)

The surface of the test piece that is in contact with the air is mounted upward on the abrasion tester, and the grinding wheel is mounted on the bracket, and a weight is added to each grinding wheel. 500g Condition wants to wear out 100r Remove the test piece, remove the surface ash and weigh it.

c)

Each test piece is tested once, and the average value of the two test pieces is taken as the test result, accurate to 10mg. The relative error of the two test pieces shall not be greater than 5%. Otherwise, it should be retested.

Wear resistance calculation

Wear resistance calculation by type (2) Calculation:

F = G₀ - G₁

(2)

In the formula:

F---- Wear value in grams (g)

Gâ‚€--- The quality of the specimen before grinding, the unit is gram (g)

G₁--- The quality of the specimen after grinding, the unit is gram (g)

This testing machine is widely used in construction materials to evaluate the durability and wear resistance of surfaces. It ensures that products meet industry standards and can withstand long-term use under various conditions. Proper calibration and maintenance are essential to guarantee accurate results and consistent performance during testing. Operators should follow the guidelines carefully to avoid errors and ensure reliable data collection. The process is both precise and systematic, making it an essential tool in quality control and material development.
