The abrasion-resistant\u00a0of the professional\u00a0industrial and mining conveyor belt is the ability of vulcanized rubber to abrasion\u00a0material as surface abrasion\u00a0while resisting force of friction, which is a mechanical property that is closely related to the service life of the industrial rubber conveyor belt, it is related to not only the use conditions, surface state of the friction and the structure of the product, but also other mechanical properties and physical-chemical properties such as viscoelastic property, there are many influencing factors for it, which is more complex than the metal abrasion.<\/span><\/p>\n

There are three types of abrasion for conveyor belt including wear abrasion, fatigue abrasion, and reeling abrasion, all of which are related to the main mechanical property of vulcanized rubber, therefore, in formulation design, it is necessary to gain the comprehensive balance for all properties.<\/span><\/p>\n

1.Effect of rubber types:<\/span><\/strong><\/p>\n

in the universal diene rubber, its molecular chain presents a good flexibility, high elasticity, and the abrasion-resistant\u00a0increases with molecular mass, when the abrasion-resistant\u00a0of vulcanized rubber raises to 100\u2103 in temperature, it decreases rapidly; polyester (EP)conveyor belt presents the best abrasion\u00a0resistant\u00a0in all conveyor belts and shows an outstanding abrasive resistant\u00a0under normal temperature, but in high temperature, its abrasive resistant\u00a0decreases rapidly; <\/span><\/p>\n

2.Effect of vulcanization system:<\/span><\/strong><\/p>\n

there is an optimum value for the abrasion-resistant\u00a0of vulcanized rubber with the increase of crosslinking density, which depends on not only vulcanization system but also dosage and structure of carbon black, this issues can be explained with the concept of optimum rigidity of abrasion-resistant when the dosage and structure of carbon black is increased, the rigidity provided by carbon black will increase. <\/span>To keep the optimum value of rigidity of vulcanized rubber, it is necessary to reduce the rigidity provided by vulcanization system, that is, reduce the cross-linking density properly, on the contrary, improve the cross-linking density of vulcanized rubber, the test shows that the more the content of single sulfur bond is, the better the abrasion-resistant\u00a0of vulcanized rubber is.<\/span><\/p>\n

3.Effect of the mixed system: <\/span><\/strong><\/p>\n

generally, the abrasion-resistant\u00a0of vulcanized rubber decreases with the particle size of carbon black, and then increases with the increase of surface activity and\u00a0dispersibility. The vulcanized rubber mixed with carbon black in the nylon conveyor belt, its abrasion-resistant\u00a0increases by double comparing with the abrasive resistant\u00a0with equivalent carbon black filled, there are multiple views on the effect of the structure of carbon black on abrasion\u00a0resistant\u00a0of vulcanized rubber, which shall be further studied. <\/span><\/p>\n

There is also an optimum value for the dosage of carbon black and abrasion-resistant\u00a0of vulcanized rubber, generally, the optimum volume of carbon black used as belt cover rubber with high abrasiveness increases with the increase of rigor level of service conditions, the new technology carbon black and white carbon black processed with silane coupling agent can improve the abrasion-resistant\u00a0of vulcanized rubber of high-strength heat-resisting conveyor belt.<\/span><\/p>\n
