Ground stone anti-skid performance and anti-skid coefficient tester

TMYGround stone anti slip performance tester, anti slip coefficient tester

1、 Overview:

The instrument adopts a CT-008 microcomputer force control instrument and a high-precision tension sensor to form a force measurement system, which has the characteristics of high force measurement accuracy, stable performance, automatic display of test results, and cyclic display of tension and anti-skid coefficient values. It meets the requirements of JC/T1050-2007 Classification and Test Methods for Anti slip Performance of Ground Stone, and is an ideal equipment for determining the anti slip coefficient of ground stone.

5Automatically calculate various parameters

6、220V,100W

IIIThe instrument consists of a CT-008 microcomputer force control device, an electric uniform force application mechanism, a pressure sensor, a working platform, and weight application weights.

four、Working Principle:

The electric force application mechanism applies horizontal tension to the tested object, generates electrical signals through pressure sensors, and sends them to the CT-008 microcomputer force control instrument for data processing and display of test results.

1Definition of slip resistance coefficient: The ratio of tangential force to vertical force when an object overcomes large static friction and just experiences sliding.

2Classification of levels

According to the different anti slip coefficients, the anti slip performance is divided into three levels.

3Working method:

Apply horizontal tension to the tested object through an electric uniform force mechanism, generate electrical signals through a pressure sensor, and send them to the CT-008 microcomputer force control instrument for data processing and display of test results.

Test area and sample: The test area or sample should not be less than 100 × 100mm. The surface of the sample should be kept clean before each test.

The test samples or areas should undergo wet and dry state tests separately, with at least 3 test samples tested for each group of tests. During on-site inspection, a set of tests will be conducted on the same ground, with the same type of stone and the same type of stone processing finish.
