How to check the static electricity performance of fabrics in anti-static overalls
Core Tip: The anti-static overalls detector is suitable for measuring the electrostatic properties of various fabrics or various plate-like products such as fibers and yarns. The instrument host consists of a corona discharge device and a probe detector.
The anti-static overalls detector is suitable for measuring the electrostatic properties of various fabrics or various plate-like products such as fibers and yarns. The instrument host consists of a corona discharge device and a probe detector. With a given high-voltage electric field, the fabric is discharged for a certain period of time, so that the fabric induces static electricity, thereby detecting the electrostatic charge amount, the half-life of the static voltage decay, and the electrostatic residual amount to show the electrostatic charging property of the fabric to be inspected.

Fourth, the operating instructions
1. Test preparation
The test is required to be carried out in an atmosphere having a relative humidity of 30% to 40% and a temperature of 20 ± 2 ° C. The sample is pre-baked at a temperature of 50 ° C for 30 minutes, and then equilibrated under a test atmosphere for 5 hours. Plug in the power socket, turn on the power switch of the main unit, and turn the high-voltage adjustment knob to make the high-voltage display display 10KV. Turn on the power switch of the control box and press the “clear” button to make the attenuation voltage on the display of the static meter display zero. The preset pressurization time is 30 seconds on the "pressurization time" timer.
The anti-static clothing testing instrument is suitable for measuring the electrostatic properties of various kinds of fabrics or various plate-shaped products such as fibers and yarns. The instrument host consists of a corona discharge device and a probe detector. With a given high-voltage electric field, the fabric is discharged for a certain period of time, so that the fabric induces static electricity, thereby detecting the electrostatic charge amount, the half-life of the static voltage decay, and the electrostatic residual amount to show the electrostatic charging property of the fabric to be inspected.
Anti-static overalls test instrument, roller friction machine, frictional charged charge tester
The antistatic overalls test apparatus is used to evaluate the electrostatic properties of the fabric after being charged in a frictional form under laboratory conditions. Anti-static overalls test equipment is an essential instrument for "Special Labor Protection Products Safety Certification" (LA certification) and "Special Labor Protection Products Production License"
Anti-static overalls test equipment (Faraday cylinder method) (A101)
The antistatic overalls test apparatus is used to evaluate the electrostatic properties of the fabric after being charged in a frictional form under laboratory conditions. This instrument is an indispensable instrument for "Special Labor Protection Products Safety Certification" (LA certification) and "Special Labor Protection Products Production License". At present, anti-static overalls test equipment has provided over-inspection services for hundreds of domestic special protective clothing companies such as Shanghai Garment Group, Shida Tools (Shanghai) Co., Ltd., Shantou Aoshan Clothing, Jiangsu Hubao Group, etc. Dozens of testing organizations, including Wuhan Environmental Protection Research Institute Co., Ltd., Taizhou Fiber Inspection Institute and Xinjiang Uygur Autonomous Region Safety Production Science Research Institute, cooperated to assist them in completing the qualification review. With the increase of sales volume and more and more professional R&D and production, the anti-static overalls test instrument not only has reliable data and stable quality, but also has become the most cost-effective personal protection detection instrument in China.
