The anti-static equipment industry is already showing a situation where hundreds of companies are in full bloom. Although the country invests relatively little in public anti-static research and development, enterprises in the anti-static equipment industry have developed their own research and development for innovation, which has made the anti-static product industry achieved remarkable results. The international market has also achieved proud results.
Method/Step
1. Electrostatic human body protection
Human body electrostatic protection products have become a series, and domestic needs can be completely independent. However, the quality of conductive threads in anti-static work clothes still has a certain gap with advanced technology, and the overall comfort of the wearability of clothing is not very high. Domestic standards do not yet have indicators for human body electrostatic protection products, but judging from national policies, such standards are just around the corner.
2. Anti-static operating system and anti-static turnover equipment
There are anti-static turnover boxes, turnover racks, workbenches, anti-static chairs, electric soldering irons, tin suction devices, storage cabinets, belts, etc. Due to the relatively simple process of this kind of product, there are a large number of domestic supplies, but some product processes need to be reformed
3. Anti-static packaging
There are various types of anti-static packaging bags, and domestic supply basically meets the demand. The anti-static performance of the product can meet the requirements of domestic and international standards, but the dimensional accuracy of rigid plastic containers. Domestic Sanwei Anti-static produces anti-static packaging products that are resistant to high temperatures of two Baidu's, and realizes commercialization for export abroad, and provides them to Intel and other companies.
4. Anti-static products
Ion static eliminators are abundant in domestic supply, including desktop, rod, air curtain, gun-type with compressed air, etc. However, there are currently no product standards in China. The domestic ion static eliminator may need to be improved in terms of reliability and the service life of the discharge needle.
5. PVC anti-static floor materials
Companies that undertake domestic engineering anti-static flooring, such as Sanwei Anti-static, use high-quality PVC anti-static flooring. Anti-static PVC floor tiles were developed earlier. Because of their low cost, good anti-static performance, and simple construction, they are used in large quantities at home and abroad. Domestically produced products need to be improved in terms of stain resistance, aging resistance, and non-linear resistance testing. The former domestic production varieties mainly include elevated anti-static raised floors, epoxy resin and polyurethane floors, PVC floor tiles, rubber plates, ceramic tiles, etc. Most of them are industrialized except for ceramic tiles. The steel and high-pressure cast aluminum floor technology in the floor has been in line with international standards and exported in large quantities abroad.
6. Test equipment
Domestic research on static detection technology is relatively backward. Anti-static attenuation tester, ion balance analyzer, electrostatic shielding tester, and other important instruments, there is no technology and no production in China. The non-contact electrostatic voltmeter has some problems in its use due to its large test error.
7. Purification products
Anti-static dust-free paper and anti-static dust-free cloth have also been serialized, and domestic demand can be completely independent. The purification grade of SW's purification paper can reach more than 10,000 grades. The domestic purification paper has reached the international level.
In addition to using the above-mentioned products to eliminate static electricity, what are the feasible methods for anti-static safety management? The manufacturer of the anti-static component box introduces to us as follows:
1. Corresponding safety measures must be taken in all processes and equipment locations that are hazardous to static electricity.
2. In areas where explosive gases may occur, ventilation measures must be strengthened to control the concentration below the lower explosive limit.
3. Workers in hazardous locations should wear anti-static shoes and overalls as needed, or set up facilities that can easily remove static electricity from the human body, such as installing grounding railings; it is strictly forbidden to wear or take off clothes and wear classic clothing in the above areas. This area: It is strictly forbidden to wipe clothes with flammable solvents (xylene, etc.) in the above-mentioned area. The conductive ground should be laid on the floor of the operation area and its conductivity should be guaranteed.
4. Operate and inspect in places where classics are produced and do not carry metal objects that are not related to work, such as keys, watches, rings, etc.
5. It is strictly forbidden to store flammable and explosive liquids that are prone to static electricity in plastic containers.
6. It is forbidden to take samples, gauge gauges or put metal objects into tanks (tank trucks) during the process of filling flammable and explosive liquids. Gauge sampling should be carried out after filling the material and leaving it still.
7. It is forbidden to use jet steam to heat flammable liquids.
8. It is forbidden to use insulated hoses to insert flammable liquid tanks for pipetting operations.
9. In the case of machine failure, liquid leakage, changing process conditions, or changing material usage, precautions must be taken to avoid electrostatic hazards.
10. It is forbidden to spray the solvent directly into the tank with a pump, and the self-flow method must be adopted.
11. For conveying flammable liquids, an appropriate safe flow rate should be selected according to the inner diameter of the pipe and the resistivity of the medium, and generally should not exceed 1 m/s.
12. The metal accessories arranged on the insulated pipe should be specially grounded.
13. Equipment, pipelines, storage tanks, and units for the production, storage, and loading, and unloading of combustible gas and flammable liquids should be equipped with grounding devices to conduct static electricity.
14. All anti-static grounding wires must be sturdy and reliable. The cross-sectional area of the grounding wire should not be less than ten square millimeters. The individual anti-static grounding resistance should not be greater than 100 ohms. When sharing with other purpose grounding electrodes, other grounding and technologies should be met. Require.
