Workshop static control reference materials
(1) Control the static electricity generation environment:
a. Humidity control. Increase the humidity as much as possible without causing corrosion, rust, or other hazards to equipment or products;
b. Temperature control. Try to reduce the temperature when possible, including ambient temperature and object contact temperature;
c. Dust control. This is an important measure to prevent adhesion (adsorption) charging;
d. Floors, table and chair fabrics and workbench pads should be made of anti-static materials and properly grounded;
e. The transportation, storage, packaging and unpacking of electrostatic sensitive products should take electrostatic protection measures;
f. The speed of spraying, flowing, conveying, winding and separating should be controlled, and the moderator should be used in the conveying pipeline of liquid, powder and other materials.
(2) Prevent the human body from being charged:
a. Wear an anti-static wrist strap;
b. Wear anti-static clothing, clothes and hats;
c. Wear anti-static footwear and anklets;
d. Wear anti-static gloves and finger cots;
e. Strictly prohibit human activities not related to work (such as doing exercises, playing around, combing hair, eating, etc.);
f. Perform ion wind bath.
(3) Process control measures:
a. Develop and implement anti-static operating procedures;
b. Use anti-static turnover, transport trays, boxes, boxes and other containers, trolleys;
c. Use anti-static tools (soldering iron, tin suction device, etc.);
d. Use anti-static packaging;
e. Set the necessary standing time for liquid materials with the possibility of electrostatic combustion and explosion;
f. Minimize the contact pressure, time and area between objects (such as the transportation of cloth, paper, wire, film material, tape, etc., transfer rollers, reels, spools and products) and limit the running speed not to be too fast.
