China Fabric Inductive Electrostatic Tester for Medical protective clothing

Product Description

Uses:

1.The instrument is suitable for measuring the electrostatic performance of fabrics or plate-like products of various non-metallic materials under specified laboratory environmental conditions. Using a given high-voltage electric field, the fabric is regularly discharged to induce static electricity on the fabric. In order to detect the magnitude of static voltage, the half-life of static voltage attenuation, and the residual amount of static electricity, it shows the electrostatic performance of the tested fabric, and guides the selection and application of professional textiles.

2. Because the instrument adopts single-chip test control technology combined with high-tech indicator programs, the test is accurate and reliable, the test operation is fully automatic, the operation is convenient and safe, and it is equipped with a printer; the large-screen liquid crystal displays the voltage of the DC high-voltage generator and the instantaneous static electricity during high-voltage discharge Voltage peak and half-life.

3. Microcomputer control, intelligent test, intuitive interface, color touch, clear and easy to use.

4. The operation is divided into automatic gear and manual gear: automatic gear, full automatic operation of the instrument. This method is suitable for most testing. The operator does not need to perform too many operations to complete the test task. The manual gear is a specialty for its professional research. A dedicated mode for operations such as personnel or factory settings.

5. Whether the fabric is electrified depends on the static voltage holding time of the sample after the high voltage discharge of the instrument. The static dissipating speed on the sample is expressed by the electrostatic half-life. It is an important assessment index for testing the electrostatic performance of fabrics. The test mechanism is as follows: After the sample is charged to a stable state in a high-voltage electrostatic field, disconnect the high-voltage power supply and let its voltage pass through ground The metal table is naturally attenuated, and the time required for the voltage attenuation to be half of the initial value is measured.

6. Fabric electrostaticity refers to the degree of fabric static electricity generation and accumulation. As chemical fiber products are more used in the field of clothing, the static phenomenon of their synthetic fiber fabrics will bring a lot of inconvenience to users, and will also guide the clothing direction for some workers in special industries to avoid accidents. The indicators of fabric static electricity are: electricity, electrostatic voltage, specific resistance and half-life of static electricity. There are three methods for testing the static electricity of fabrics: half-life method, triboelectric voltage method, and charge surface density method. This manual mainly introduces the induction static tester of the half-life method.
