China Carbon Black Supplier - Beilum Carbon - www.beilum.com

  The main use of carbon black is in tires and rubber industry. The amount of Rubber carbon black used in tires accounts for more than 80% of the entire rubber industry. Carbon black used in rubber products other than tires accounts for 20% of the carbon black used in rubber.  Carbon Black N330 Tire rubber | The role of carbon black in rubber: 1. Play a reinforcing role to increase the wear resistance and service life of rubber products. 2. Use filler to save costs. Tire rubber | Classification of carbon black for rubber Carbon black for rubber mainly depends on the physical properties, wear resistance and tensile properties of carbon black. Currently, the common carbon black for rubber is Carbon Black N220,  Carbon Black N330 , Carbon Black N550, Carbon Black N660, Carbon Black N774 and other series. Tire rubber | The role of different types of carbon black in rubber: High wear resistance: Carbon Black N110, Carbon Black N220,  Carbon Black N330 , N339, etc. Reinforced types: Carbon B

  The particles of carbon black itself are very easy to aggregate into larger particles, which are difficult to stably disperse in the water-based system. According to the characteristics of carbon black, it is poorly dispersed and difficult to disperse.  Conductive Carbon Black  supplier in China. Therefore, the solution to the dispersion problem of carbon black is to use carbon black The premise of black, especially when using carbon black, more attention should be paid to the dispersion problem. What are the factors affecting the dispersion of conductive speciality carbon black? The physical properties of carbon black itself, dispersants, and dispersing equipment, especially when using carbon black for coloring, uneven dispersion of carbon black powder will lead to serious consequences, directly affecting the hue, blackness and hiding power of the product. Of course, when using carbon black, it is also necessary to pay attention to the dispersion of  conductive carbon black . Influe

  The reinforcing effect of carbon black is mainly that the addition of carbon black changes the structure of the rubber and produces a C-phase structure. In vulcanized rubber, if the carbon black is well dispersed, and a C-phase structure is formed on the surface of each carbon black particle , Phase C plays a skeleton role to connect phase A and phase B. Forming an overall network of rubber macromolecules and fillers, changing the structure of the vulcanized rubber, thus improving the physical and mechanical properties of the vulcanized rubber. Reinforcement mechanism of  carbon black  Surface adsorption layer theory This theory believes that Black carbon and rubber generate a microscopic multi-phase inhomogeneous structure, which is a reinforcing mechanism of composite materials. Nuclear magnetic resonance studies have confirmed that there is an adsorption layer composed of two types of rubber macromolecules on the surface of carbon black. The inner layer of about 0.5nm close to the

  Usually the amount of  carbon black pigment  added to black paint is more than 6%, and the amount of carbon black added to some black paints reaches 15%. Of course, this also depends on what kind of paint is produced and what kind of carbon black product is selected. Generally speaking, if you choose ordinary  pigment carbon black , you need to add more black carbon , but if you choose high blackness carbon black pigment, you need to add much less. In some paints, the amount of carbon black added can be as low as less than 5%. This is also the reason why many friends cannot get an accurate amount of carbon black added to the paint. When choosing  carbon black pigment  for paint, you must pay attention to the blackness and tinting strength of the pigment black. These two carbon black indicators greatly affect the addition ratio of paint carbon black. Blackness is the main indicator of carbon black for paint. When coloring carbon black with black paint, the blackness of carbon black wi

  Carbon black Powder  in the application process must be dispersed to the composite optical properties of the microparticle state, so the dispersion of carbon black will affect some other indicators of carbon black, such as colour, blackness, etc., which may affect the user’s experience. Carbon Black Powder is better dispersed and finer than  granular carbon black . This results in more contact points between the carbon black aggregates, which does more work for the dispersion to separate the carbon black particles and ultimately achieve the highest blackness and colouration. The dispersion of carbon black is affected by the degree of structure, the better the dispersion the better the colouring strength.   Carbon Black Powder  is easy to disperse in paint, so the colouring effect is a little better.

  Judging the conductivity of  conductive carbon black  through the oil absorption value index Oil absorption value (DBP) is commonly used to express structural properties. The greater the DBP value, the higher the structural properties. The physical properties and conductivity of conductive carbon black depend on the volume and microporosity of these aggregates. The greater the oil absorption value of  conductive carbon black  DBP, the easier it is to form aggregates with a large number of particles and complex structures, and the more aggregates there are per unit mass. Therefore, under certain conditions, the greater the DBP oil absorption of carbon black, the stronger its conductivity. Based on the particles that make up the basic aggregates and morphology of carbon black, high-structured carbon black aggregates have large, polymeric particles. This branching increases the contact between aggregates, which can lead to high conductive properties. Judging the conductivity of carbon b
