Precipitated silica tread compound in the truck's role
℃, the spring rate will increase, while its at 0 ℃ Dissipation factor would decrease, but the loss tangent value in the 0 \traction and rolling resistance performance between both get a better comparison with the whole black plastic than the blue kind of silica that can greatly reduce the 60 \Two kinds of surface area larger than the reduction of silica in the 60 \4 Conclusion of all natural rubber truck tires with low rolling resistance rubber formulations in terms of surface, when the promotion of the same dosage,[link widoczny dla zalogowanych], an increase in surface area silica or increase the dosage, you can significantly reduce the associated physical properties of vulcanized rubber. When the silica surface area increases, the effect gradually become more prominent. These effects may be through the use of bis (3 thirteen silyl oxy-propyl) tetrasulfide coupling agent can be balanced. When increasing the amount of accelerator,[link widoczny dla zalogowanych], if the silica was the interference of the curing system by increasing the surface area of silica or increase the amount of full compensation, then. The role of silane coupling agent in the dosage of silica from the equivalent weight of the weight range of 6 to l0 is greatly reduced. In terms of scope in respect of coupling agent,[link widoczny dla zalogowanych], silane coupling agent when the increase in time. Only the difference between the increase in torque rheometer is significant. As compensation for the role of agents, heat is 100 ℃, the reduction and increase in no doubt by the resilience of the increased use of silica. Therefore, to compensate for the amount of silica and its surface area, in the promotion of appropriate dosage. Since the activity of silica and carbon black rather, it prevents the curing system damage. This allows reduced to achieve an ideal balance of performance related vulcanizate of silane coupling agent in need. Take the natural rubber-based formulations in terms of deck cavity, has found that,[link widoczny dla zalogowanych], whether silica or silane coupling agent, to rate in terms of the amount involved, all door Mooney viscosity of no more too. Replacing carbon black with silica can significantly reduce the 6O ℃ when the loss tangent,[link widoczny dla zalogowanych], which has nothing to do with the promotion of dosage. In all three types of silica (when they 6O ℃ decreased loss tangent values are the same speed), the loss tangent decrease in direct proportion with the amount of silica. This shows that replacing carbon black with silica would lead to all-natural rubber-based truck tire tread compound reduces rolling resistance.
