Antistatic devices

Polonium is a radioactive, low-melting metalloid. It is a useful source of a particles (helium-4 nuclei they are described in more detail in Section 15.11) and is used in antistatic devices in textile mills the a particles reduce static by counteracting the negative charges that tend to build up on the fast-moving fabric. 

Polonium decays by emission of an alpha particle, He. It is used in antistatic devices in textile mills to counteract the buildup of negative charges on fast moving fabric. 

Polonium is a strong emitter of a-particles approximately 1 gram of °Po emits 140 watts of heat energy. For this reason, it is used as a source of thermoelectric power in satellites. It is also utilized as a source of neutrons (when mixed with beryllium), as an antistatic device in industrial equipment, and in brushes that remove dust from photographic film, see also Curie, Marie Sklodowska Halogens Radioactivity Radium Uranium.

Trimming for thin sections produces a very small square block and is eased considerably by the use of a diamond trimming tool. Thin sections are cut at around -100 °C and this stage requires a little patience. Both diamond and glass knives can be used, but for ease (making high quality glass knives is not easy) diamond knives are to be preferred. Static electricity can be a problem, particularly with diamond knives and this can be alleviated with an antistatic device (Diatome).

Another source of radioactive material sometimes used in the semiconductor industry are antistatic devices containing polonium-210, an alpha emitter. While used extensively in the past, currently, the use of these sources is primarily limited to certain mask-making operations. T q)ically the antistatic devices are leased from the manufacturer for a specific period of time (e.g., 12 months). The supplier of the antistatic device normally performs a periodic wipe test of the source, but the users should maintain...

Mixing cellulose esters in nonpolar hydrocarbons, such as toluene or xylene, may result in static electricity buildup that can cause a flash fire or explosion. When adding cellulose esters to any flammable Hquid, an inert gas atmosphere should be maintained within the vessel (132). This risk may be reduced by the use of conductive solvents in combination with the hydrocarbon or by use of an antistatic additive. Protective clothing and devices should be provided. 

Even if the device has been properly calibrated for the particular gas in air, some analyzers such as catalytic bead types will not function in oxygen deficient atmospheres containing less than about 10 vol% oxygen. Some portable analyzers are supplied with antistatic tubing but others are supplied with nonconductive tubing such as Tygon. 

PEN has antistatic protective properties and has been used in optical devices. Compared with PET, PEN-based antistatic films show better mechanical properties, higher surface resistivity and less peeling from a polarizing plate [84],...

BXL Plastics ERP Division is to introduce new grades of antistatic and conductive closed-cell crosslinked PE and ethylene copolymer foam at the Internepcon Exhibition to meet a growing demand from the electronics industry, for ways of minimising the effect of static electricity on circuits embodying static-sensitive devices, particularly using metal oxide/silicone technology. Very brief details are noted of Evazote C conductive closedcell, crosslinked ethylene-vinyl acetate copolymer foam.
