The amount of carbon black in the rubber can significantly affect the physical and mechanical properties of the vulcanized rubber. Practice has shown that hardness, tensile strength and heat build-up increase monotonically with the increase of carbon black. The rebound rate, elongation, and the like appear to decrease monotonously. Tensile strength, tear strength, and wear resistance are maximized with the increase of carbon black, and the better the reinforcement, the more obvious the maximum value appears. With the increase of the amount of carbon black, the wear resistance of vulcanized rubber is significantly enhanced at the beginning. After increasing to the maximum value, the carbon black is increased again, and the wear resistance is no longer changed significantly. When the total specific surface area of the carbon black in the rubber is equal, the carbon black of the larger particles has better wear resistance, and the smaller particles have less wear resistance, which is related to the dispersion of the carbon black Mu kapiira. obunene bw’obutundutundu bwa kaboni omuddugavu gye bukoma okuba obutono, okusaasaana gye kukoma okukendeera, bwe kityo ne kikendeeza ku buziyiza bw’okwambala.

The basic properties of carbon black and the effect on the mixing of carbon black rubber are very significant. Due to the different properties of carbon black, the mixing speed and dispersion effect of carbon black are different, and various carbon blacks have different Mooney viscosities. . The powder feeding rate of carbon black in rubber is closely related to the particle size and structure. The smaller the particle size and the higher the structure, the longer the mixing time required. Carbon Omuddugavu alina obunene bw’obutundutundu obutono n’ensengekera entono alina okusaasaana okubi n’obudde obw’okutabula obuwanvu. akaboni kaboni omuddugavu alina ekikolwa ekibi eky’okusaasaana bw’ogeraageranya n’omuddugavu agumikiriza okwambala okungi, era obunene bw’obutundutundu bw’ebintu bino byombi si bwa njawulo nnyo kubanga ensengekera y’omukutu omuddugavu eri wansi.
The carbon black kneading glue is placed in a solvent, and there is a partially insoluble gel particle, which is a combination of carbon black and rubber called a carbon black gel or a bonding rubber. The amount of carbon black gel produced is related to the type and amount of carbon black, the type of rubber, and the conditions of the mixing. The amount of carbon black gel produced is an important measure of the effect of carbon black on rubber Okunyweza. Gel ye macromolecule ya kapiira egattibwa ne kaboni omuddugavu oluvannyuma lw’okumenya, era ekwata atomu ya haidrojeni eya kaboni omuddugavu okukola ekiyungo kya kemiko eky’okugatta kwa kapiira ne kaboni omuddugavu n’enkolagana ey’omubiri ey’okuyungibwa kw’omubiri. Omugatte gw’omukutu ogufaananako bwe gutyo gukolebwa okugatta kwa kemiko n’omubiri {4} n’obutundutundu bw’obutundu structure. The smaller the particle size and the higher the℃of structure, the easier it is to form a gel. Carbon black is more likely to be produced than carbon black having a high wear resistance particle size. It is more remarkable in rubber with low unsaturation. The amount of gel produced varies with the type of rubber. Natural gel, styrene butadiene rubber, butadiene and neoprene produce much more gel than butylbenzene and butadiene rubber. The low℃of unsaturation of butyl and ethylene propylene is almost impossible to form a carbon black gel. The temperature of the rubber is also closely related to the amount of carbon black gel. At high temperatures, the gel is promoted. During the mixing process, the carbon black gel can continue to form in the rubber. The higher the temperature is. The faster the gel content increases. The Mooney viscosity of the rubber compound has a great relationship with the rubber processing technology, and the high Mooney viscosity rubber compound often causes difficulties in the processing. The viscosity change of the carbon black rubber compound has a direct relationship with the carbon black gel. The larger the gel in the carbon black rubber Compound, mooney viscosity gyekoma okuba waggulu ekirungo kya kapiira. gye kikoma okuba ekirungi carbon black particle size, ensengekera gyekoma okuba waggulu ate dose gyekoma okuba waggulu, viscosity ya rubber compound gyekoma okuba waggulu. ensonga eri nti ensonga zino zitumbula gel formation.
