重型耐磨保送带组成原料中的碳黑在其外表的粗糙度主要是指炭黑粒子在构成过程中,由于碳氢化合物高温熄灭裂解时,炭黑成粒过程随同有猛烈氧化,使炭黑粒子发作氧化腐蚀现象,构成了零点几纳米至几纳米直径的孔洞,于是产生了炭黑粒子的外表粗糙现象,粗糙对补强不利,槽法炭黑粗糙度比炉法炭黑的大,新工艺炭黑外表比拟润滑,此外炭黑的其他性质还有光学性质、密度和导电性等;
The roughness of carbon black in the raw material of heavy duty wear-resistant belts mainly refers to the roughness of carbon black particles in the process of composition. Because of the fierce oxidation of carbon black particles during the high temperature quenching and cracking of hydrocarbons, the carbon black particles are oxidized and corroded, forming holes with a diameter of several nanometers to several nanometers at zero point, resulting in the roughness of carbon black particles. Roughness is disadvantageous to reinforcing. The roughness of carbon black in tank process is larger than that in furnace process. The appearance of carbon black in new process is comparable to lubrication. In addition, other properties of carbon black include optical properties, density and conductivity.
炭黑对优质橡胶保送带加工性能的影响:炭黑的粒径、构造和外表性质等性能对橡胶的加工性能有重要的影响,表如今工业保送带在停止混炼、压延、挤出和硫化各工艺过程中及混炼胶的流变性能上:
Carbon black has an important influence on the processing properties of high quality rubber belts. The particle size, structure and appearance properties of carbon black have an important influence on the processing properties of rubber. It is shown that the industrial belts have the rheological properties in stopping mixing, calendering, extrusion and vulcanization and in the process of mixing.
容纳胶是在炭黑汇集体链枝状构造中屏蔽的那局部橡胶,又称为吸留橡胶,容纳胶的数量由炭黑的构造决议,构造高,容纳胶多,其活动性遭到极大的限制,所以在一些问题的处置中常把它看成是炭黑的一局部,当然这种见地不够精确,当剪切力增大或温度升高时这局部橡胶还有一定的橡胶大分子的活动性,依据炭黑汇集体的电镜观测、模型、计算等大量研讨工作提出了经历公式也就是炭黑汇集体构造度越高,即汇集体链枝越兴旺,则容纳胶越多,但在计算填充炭黑胶的应力时,发现计算的结果比实测值高,阐明在这样的拉伸条件下,容纳胶中的橡胶大分子还是有一定的活动性;

Containing rubber is the part of rubber that is shielded in the dendritic structure of carbon black sink collective chain. It is also called absorbing rubber. The quantity of containing rubber is determined by the structure of carbon black. Its structure is high and it contains more rubber. Its activity is greatly limited. So it is often regarded as a part of carbon black in the treatment of some problems. Of course, this view is not accurate enough. When the shearing force increases or the temperature increases, it will be regarded as a part of carbon black. This part of rubber has certain activity of rubber macromolecule. According to a lot of research work on the observation, model and calculation of carbon black sink, the empirical formula is put forward, that is, the higher the structure degree of carbon black sink is, that is, the more prosperous the chain branches of carbon black sink are, the more rubber is contained. But when calculating the stress of carbon black rubber filling, it is found that the calculated result is higher than the measured value. The rubber macromolecule contained in the rubber still has certain activity under tensile condition.
炭黑性质对混炼过程及混炼胶的影响:炭黑的粒径、构造和外表性质对混炼过程和混炼胶性质均有影响:
The effects of carbon black properties on mixing process and rubber properties: particle size, structure and surface properties of carbon black have effects on mixing process and rubber properties.
尼龙保送带带炭黑本身性质对混炼吃料及分散上的影响:炭黑的粒径越细混炼则越艰难,吃料慢,耗能高,生热高,分散越艰难,这主要是由于粒径小,比外表积大,需求潮湿的面积大,炭黑构造对分散的影响也很明显,高构造比低构造的吃料慢,但分散快,这是由于构造高,其中空隙的体积比拟大,扫除其中的空气需求较多的时间,而一旦吃入后,构造高的炭黑易分散开;
The influence of the properties of carbon black in nylon belts on mixing feeding and dispersion: the finer the particle size of carbon black, the harder it is to mix, the slower it is to eat, the higher the energy consumption, the higher the heat generation and the harder it is to disperse. This is mainly due to the smaller particle size, the larger the surface area, the larger the area of wet demand, and the obvious influence of carbon black structure on the dispersion. The high structure is slower than the low structure, but faster to disperse. Because of the high structure, the volume of the voids is comparatively large, which requires more time to clean up the air. Once eaten, the carbon black with high structure is easy to disperse.
炭黑本身的性质对保送带热硫化橡胶在技术性能上的影响:炭黑粒径对硫化胶的拉伸强度、撕裂强度、耐磨性都具有决议性作用,粒径小,撕裂强度、定伸应力、硬度均进步,而弹性和伸长率降落,紧缩永世变形的变化很小,是由于粒径小,比外表积大,使橡胶与炭黑间的界面积大,两者间互相作用产生的分离胶多;
The influence of the properties of carbon black on the technical properties of heat vulcanized rubber for conveyor belts: the particle size of carbon black has decisive effect on the tensile strength, tear strength and wear resistance of vulcanizates. The particle size of carbon black is small, the tear strength, fixed stretch stress and hardness are improved, while the elasticity and elongation decrease, and the change of shrinkage and permanent deformation is very small, because the particle size is small and the specific surface area is large, which makes the rubber and rubber and the rubber have better mechanical properties. The interface area between carbon black and carbon black is large, and the separation gel produced by the interaction between carbon black and carbon black is large.
炭黑的构造对定伸应力和硬度均有较大的影响由于填料的存在就减少了硫化胶中弹性橡胶大分子的体积分数,构造高的炭黑容纳胶多,就更大水平地减少了橡胶大分子的体积分数,构造对耐磨耗性只要在苛刻的磨耗条件下才表现出一定的改善作用,其构造对其他性能也有一定的影响。
The structure of carbon black has a great influence on the constant elongation stress and hardness. The volume fraction of elastic rubber macromolecule in vulcanizate decreases because of the existence of filler, and the volume fraction of rubber macromolecule decreases more horizontally when the carbon black with high structure contains more rubber. The structure can improve the wear resistance of rubber macromolecule only under severe wear conditions, and its structure can improve other properties. Can also have a certain impact.
