Effect of nonionic and ionic surfactants on zeta potential ...

The effect of multifunctional additive (MFA) on filler dispersion in carbon-black- (CB) and silica-filled natural rubber (NR) compounds has been studied. Silica dispersion, measured by computer-aided image analysis and scanning electron microscopy (SEM), showed a substantial improvement when MFA concentration is increased from 1 to 3 phr.

Effect of Carbon Black Dispersion on the Mechanical ...

Abstract The effect of surface modifications of carbon black (CB) on its dispersion in polyether polyol and CB/ polyurethane (PU) foams and the properties of the CB/PU composite foams was investigated. Pristine CB (p-CB) was oxidized in nitric acid

Effect of carbon black dispersion on carbon black and ...

Jun 05, 2009· 1. Introduction. Carbon black, obtained from the incomplete combustion of organic materials, like petroleum and coal, is a fine-pigment powder. It has a widespread use in several industries from electrochemistry to waste water treatment and paintings,, .Its application requires fine and homogenous dispersion of the powder into liquid which is usually water due to environmental issues …

Effect of Multifunctional Additive on Filler Dispersion in ...

A study has been made of the mechanics of mixing of carbon black in rubber by determining the influence of agglomerates in the mix on the final properties of the vulcanizate. It is suggested that the mixing starts with the forming of soft agglomerates which contain polymer and black in about the proportion of the void ratio aa determined by oil ...

Abstract The effect of surface modifications of carbon black (CB) on its dispersion in polyether polyol and CB/ polyurethane (PU) foams and the properties of the CB/PU composite foams was investigated. Pristine CB (p-CB) was oxidized in nitric acid

Effect of reynolds number on the dispersion of carbon ...

The effect of the filler dispersion on the electrical conductivity and mechanical properties has been studied. Keeping the graphite content constant and increasing the ratio of carbon black to nanotubes, the conductivity and the flexural modulus increased linearly at different graphite contents.

Improve dispersion of carbon black? / Optimized ...

The effect of carbon black surface area on dispersion was considerably less in SBR-1712 with no loose oil addition. In EPDM, upside-down mixes of different grades of black at varied black/oil loadings produced some notable changes in the dispersion response to carbon black DBPA. At some of the high black/oil ratios, low DBPA was actually ...
