Is it necessary for pharmaceutical clean protective clothing to have anti-static properties?
In a pharmaceutical factory, anyone entering the production area should change clothes as required. This is because the human body is the largest source of contamination in a cleanroom. According to statistics, the proportion of dust generation in the air in the clean room is 5%-10%, the proportion of dust generation by decoration is 20%-30%, the proportion of dust generation by gas and liquid is 5%-10%, and the proportion of dust generation by machinery is 20%-30%. The proportion of dust generated by personnel accounts for 30%-40%. In order to ensure human safety and ensure the quality of drugs, personnel entering the production workshop of the pharmaceutical factory will wear clean clothes.
Clean clothing, also known as sterile clothing, dust-free clothing, and purification clothing, as the name suggests, clean clothing needs to have dust-proof performance. In addition to dust-proof function, is it necessary to have anti-static performance for pharmaceutical clean protective clothing?
The clean clothes in the pharmaceutical industry need to have anti-static function, but the static index of anti-static function is not as high as that of electronics and chemical industry.
Most clean rooms require the environment to be under constant temperature and humidity conditions for a long time, and the static electricity generated in the clean room is more difficult to eliminate. Static electricity may cause production equipment to fail, product quality to decline, and powder adsorption to harm the health of producers. Sparks generated by frictional static electricity may also cause explosions. the occurrence of the accident.
Therefore, clean clothes must not only have dust-proof function but also have anti-static function.
