Heavy abrasion resistant conveyor belt material refers to carbon black carbon black particles in the formation process on the surface roughness is mainly due to cracking of hydrocarbon combustion at high temperature, the carbon black particle formation process with severe oxidation, the oxidation of carbon black particle erosion phenomenon, forming a hole zero point several nanometers to several nanometers in diameter, so the rough surface of carbon black particles, roughness on reinforcing bad channel black roughness than carbon black, the new technology of carbon black surface is relatively smooth, in addition to other properties of carbon black and optical properties, density and conductivity etc.;

Effect of conveying black carbon on the performance of high quality rubber belt processing: have important influence on processing properties of carbon black particle size, structure and surface properties on the properties of rubber, in the industrial belt in mixing, calendering, extrusion and vulcanization process and rheological properties of blends can:

Inclusive glue is part of the rubber shield in the carbon black aggregates chain dendritic structure, also known as absorbing rubber, adhesive quantity tolerance decided by carbon black structure, containing gum and its activity, have been restricted, so in dealing with some problems often regard it as a part of the carbon black of course, this view is not accurate enough, the activity when the shear stress increases or temperature when this part of rubber and a certain rubber molecule, according to the SEM observation, the calculation model of carbon black aggregates, a lot of research work is also put forward the empirical formula of carbon black aggregates structure is higher, i.e.aggregates chain branches more developed it contained more stress in the adhesive, but the calculation of carbon black filled rubber, found that the calculation result is higher than that in the measured value, the tensile conditions of inclusion rubber molecules in gel also There is a certain activity;

Carbon black properties of the mixing process and the effect of mixing: the carbon black particle size, structure and surface properties of the mixing process and the effect of mixing of colloidal matter:

Nylon conveyor belt with black nature of the mixing and feeding effect of dispersing the carbon black particle size becomes finer, more difficult mixing, slow feeding, high energy consumption, high heat dispersion, more difficult, this is mainly because of the small particle size, large surface area, need humid area, carbon black the structure of the dispersion effect is also very obvious, high structure than the low structure of feed is slow, but dispersed quickly, this is because the structure of the high void volume is relatively large, which excluded the air need more time, and once when eaten, high carbon black structure easily dispersed;

The influence on the properties of carbon black belt heat vulcanized rubber on the technical performance: the decisive role of carbon black particle size of vulcanizate tensile strength, tear strength, abrasion resistance, small particle size, tear strength, tensile stress and hardness are improved, and the elasticity and elongation decreased, changes of compression deformation because of the very small, small particle size, large surface area, so that the rubber and carbon black industry area, combined with the gum produced by the interaction between the two;

Carbon black structure on elongation greater impact force and hardness are reduced because of the existence of filling volume fraction of elastic rubber molecules in vulcanizate, carbon black structure high gum is more inclusive, reduce the volume fraction of rubber molecules, only under harsh conditions in wear performance a certain role in the improvement of structure resistance, the structure also has some influence on other performance.
