Electrostatic elimination

An interesting feature noted in the washed cotton studies was that cottons from each of the washed treatments were divided into two parts. One part was processed using an electrostatic eliminator bar on the doffer of the card and the other part without. In general, much more fine dust was separated from the...

Because of its high strength, high modulus, low extend, high wearabihty and conductivity, carhon fiber is used as filter materials for gas and liquid, insulatuig material for high temperature, catal5 er carrier and electrostatic eliminator (Zhao, 2002), and it is applied in oil gas field to a certain extent. 

In reduced electrostatic units, the factor is eliminated and the Poisson equatic becomes ... 

Static eliminating devices that ionize the atmosphere around the device are available. Static eliminators are divided into two main groups silent (corona) discharge eliminators, such as inductive eliminators, or high voltage eliminators which initiate an impact ionization of the air by applying strong electrostatic fields, and radioactive eliminators that provide a multitude of ions from independent ion sources (9). 

Electrostatic shocks Eliminated at high moisture conrenr. Increased at low moisture contciu, causing discomfort to occupants and damage to electronic components. High explosion risk. 

Although the nature of the general polar effect suggested by Kamernitzsky and Akhrem " to account for axial attack in unhindered ketones is not clear, several groups have reported electrostatic interactions affect the course of borohydride reductions. Thus the keto acid (5a) is not reduced by boro-hydride but its ester (5b) is reduced rapidly further, the reduction of the ester (6b) takes place much more rapidly than that of the acid (6a). Spectroscopic data eliminate the possibility that in (5a) there is an interaction between the acid and ketone groups (e.g. formation of a lactol). The results have been attributed to a direct repulsion by the carboxylate ion as the borohydride ion approaches. " By contrast, House and co-workers observed no electrostatic effect on the stereochemistry of reduction of the keto acid (7). However, in this compound the acid group may occupy conformations in which it does not shield the ketone. Henbest reported that substituting chlorine...
