The mechanism of carbon black enhancement The mechanism of carbon black enhancement are presently Perturbed hard-chain theory , crystal colloid theory, filler network theory and Van Der Waals network theory. 1??·??????????í??van der Waals theory Abstract Generalized van der Waals theory is used to establish a partition function that considers the effect of density on rotational and vibrational motions in addition to translational degrees of freedom. A three-parameter equation of state is derived from this partition function. The equation of state is applicable to small, spherical (argon-like) molecules and also to large, structurally complex molecules, including polymers. Parameters are presented for three polymers and twenty-two common fluids including light hydrocarbons, heavy hydrocarbons, nitrogen, carbon dioxide, hydrogen, carbon monoxide, hydrogen sulfide, sulfur dioxide, and water. The equation of state gives good liquid densities, and vapor pressures, and fair second virial coefficients. 2??Perturbed hard-chain theory ·?×????????í??

By allowing the junction?\creation rate and the probability of loss of junctions to depend on the second invariant of the rate?\of?\strain tensor, more realistic constitutive equations were obtained. Two rheological models are proposed by assuming two different mechanisms for the effect of the rate of strain on the kinetics of the network. The experimental data on three fluids (representative of eight viscoelastic fluids) are used to test the models in various flow situations. For steady simple shearing and small?\amplitude, sinusoidal simple shearing, both model A and model B are capable of fitting the four functions ??,−(?? 11 −?? 22 ), ????, andG' rather well over many decades of shear rate or frequency. For suddenly changing flow experiments model A is inadequate. Model B however appears to be the only rheological equation which can fit simultaneously the steady shear, complex viscosity, stress growth, and stress relaxation functions. For stress growth, the agreement with the experimental data is remarkable, especially after the other models were shown to fail drastically. Finally, an interpretation of the stress growth and relaxation phenomena is given in the light of the modified theory. |
