two、Ceramic tile comprehensive testerPrinciple and Structure

This instrument consists of a supporting plate, a movable left support, and a right support, forming a Cartesian coordinate system. First, probe the three equally high support pins on the flat plate to support the standard plate (with the same external dimensions as the ceramic tiles), adjust the dial gauge value to the appropriate position, and record the reading. Then, replacing the standard board with the tested ceramic tiles, six indicator parameters were measured separately without moving the measurement points. The left and right supports, as well as the center measuring support, can move parallel on a flat plate to form spatial coordinates at different positions, in order to adapt to the measurement of ceramic tiles of different specifications and sizes.

Measurement parameters and their definitions

1. Edge straightness: The deviation of the center of an edge from a straight line in the plane of a brick (see Figure-9), expressed as a percentage, calculated using the following formula:

C

——×100%

L

In the formula: C - the deviation of the center of the measuring edge from the straight line.

L - Measure edge length.

2. Right angle: Place the corners of the brick tightly against a right angle calibrated with a standard plate, measure its deviation from the standard right angle (see Figure-4), and express the right angle as a percentage using the following formula:

δ

——×100%

L

In the formula, the deviation value measured at a distance of 5mm from the corner between the measuring edge of the δ - brick and the corresponding edge of the standard plate.

Measure the edge length of L-brick.

3. Edge curvature: The distance between the midpoint of the brick edge and the straight line formed by the two top corners of the edge (see schematic diagram -2). The curvature of the edge is expressed as a percentage and calculated using the following formula:

△S

­­­ ———×100%

L

In the formula: △ S - the midpoint of the brick edge, the distance from the straight line formed by the two vertices of that edge.

L - Measure edge length.

4. Warping degree: The three corners of the brick determine a plane, and the fourth corner deviates from that plane by a distance (see schematic diagram -1). The curvature is expressed as a percentage and calculated using the following formula:

△W

­­ ———×100%

D

In the formula: △ W - the distance of the measured angle from the plane determined by the other three angles.

The diagonal length of D-brick.

5. Center curvature: The distance that the midpoint of a brick deviates from the plane determined by three of the four corners of the brick (see Figure-8).

The central curvature is expressed as a percentage and calculated using the following formula:

△C

­­­­ ———×100%

D

In the formula: △ C - the distance that the midpoint of the brick deviates from the plane.

The diagonal length of D-brick.

6. Edge length: Place the corners of the brick tightly against the right angle of the calibration angle of the standard plate, and measure its deviation from the standard (see Figure-3). Calculate using the following formula:

L+δ

In the formula, the deviation value measured at a distance of 5mm from the corner between the measuring edge of the δ - brick and the corresponding edge of the standard plate.

L - The length of the corresponding edge of the standard plate.
