I. Overview of ceramic tile recovery coefficient tester
TD3810-5A Impact resistance tester for ceramic bricks (also known as recovery coefficient tester) is used to determine the impact resistance of various bricks by measuring the recovery coefficient. It is mainly used to determine the recovery coefficient of various ceramic wall tiles to determine the impact resistance of ceramic tiles. the tester is manufactured according to Q/JYY033-2001 "CHY type Ceramic Tile Recovery Coefficient Tester" and conforms to GB/T3810.5-1999 "Test Method for Ceramic tiles - Part 5: Determine the impact resistance of brick by measuring the coefficient of recovery "and ISO10545-5:1996" Ceramic tiles - Part 5: Determine the impact resistance of brick by measuring the coefficient of recovery "requirements, the tester is simple to operate, intuitive reading, a sample placed without calculation can be read back height and recovery coefficient.
Criteria:
GB/T3810.5-1999 "Ceramic tile test methods - Part 5: Determination of brick impact resistance by measuring the coefficient of recovery"
ISO 10545-5:1996 "Ceramic tile - Determine the impact resistance of brick by measuring the coefficient of recovery"

Iii. Principle of TD3810-5A Impact resistance tester (also known as recovery coefficient tester) for ceramic bricks
the steel ball of φ19 is dropped on the sample from 1m height and its bounce height is measured to determine the recovery coefficient.
IV. Installation and leveling of TD3810-5A impact resistance tester (also known as recovery coefficient tester) for ceramic bricks
after the measuring instrument is unpacked and accepted according to the packing list, first check whether there is any loosening, then install the footing on a solid platform, observe the horizontal bubble on the base, adjust the footing to make the instrument level, lock the locking nut of the footing, then put a steel ball into the ball socket on the top surface of the plunger, and then put the supporting ball socket down on the steel ball, and then connect the signal connection line according to the instructions:
V. Application method of TD3810-5A Impact resistance tester (also known as recovery coefficient tester) for ceramic bricks
the first step is to prepare the sample according to GB/T 3810.5-1999:
in the second step, rotate the handwheel to lower the supporting plate to the appropriate position, put the sample into the back of the fixture, and then reverse rotate the handwheel to tighten the sample:
the third step, plug in the power supply, put another steel ball into the ball socket of the nose, the steel ball will be automatically sucked.
the fourth step is to press the "drop" button and the steel ball falls down. after the ball bounces for the second time, the wrench is lifted upward with the hand, the ball catching board bounces back to catch the ball, and the steel ball is recovered from the front exit with the hand. At this time, the instrument has automatically measured the recovery coefficient of the sample and the bouncing height of the steel ball.
the fifth step, press the reading keyboard, the instrument displays the sample recovery coefficient, press the conversion key, the instrument displays the steel ball bounce height.
the sixth step is to take out the sample and prepare for the next test. after the test is finished, turn off the power and clean the instrument.

Vi. Precautions for TD3810-5A Impact resistance tester (also known as recovery coefficient tester) for ceramic bricks
1. Due to the micro-uneven surface of the ceramic tile, the steel ball may bounce back and hit the inner wall of the collection tube. at this moment, you can adjust the impact position by turning the spanner, gently turning the motor head, and then press the clear key to clear the last invalid impact. Then install the steel ball and press the landing key to do it again.
2. Give the guide plug butter (through the butter nozzle) periodically.
3. the laboratory must conform to the national standards.
