About a possibility of increasing the adhesion strength between mineral glass and polymeric binder under radio-frequency induction plasma treatment

The effect of pretreatment technologies of carbon fibers by different electromagnetic methods on their mechanical characteristics has been examined. The methods of cold plasma and ultraviolet radiation were used. Such a treatment improves adhesion strength of a metal coating with fibers for production of carbon-filled plastics with high interfacial shear durability. By experiments it has been found out that the plasma treatment method is the most effective. The study and experiment results are presented.

Before And After

The manufacture technology of spherical WC powder has been studied by using of induction plasma. We can get spherical powder above 85% in the powder through changing several parameters. And the hall flow-ability, the oxygen content , particle size of powder before and after plasma treatment have been compared. The results were shown that oxygen contents was deduced markedly, and the plasma method can control the particle size easily.

Frequency Plasma

A radio-frequency plasma system (RF) was used to investigate the removal of microorganisms from water.Plasma generated by RF radiation can produce active compounds (H•, •OH, H2O2, O3, etc.) that have a highoxidation potential and can kill microorganisms present in water (fecal coliforms and total coliforms). Thefrequency of the plasma system was set to 3.0, 3.3 and 3.7 MHz and applied to river water for 60 minutes. Theresults show that in all runs, the pH of the water produced was in the range from 7.4 to 7.9. The removalefficiencies of fecal coliforms achieved were between 83.75 and 95% and were higher than the removalefficiencies of total coliforms, which were between 82.61 and 93.48%. Meanwhile, the death rate (kD) of fecalcoliforms wasfaster than that of total coliforms. Therefore, the removal of total coliforms is the key to removingmicroorganisms fromwater. RF plasma treatment can be used for treatment of drinking water to decreasemicroorganisms.
