White carbon black technology is relatively developed in our country, and there are various ways to use white carbon black. Nowadays, this chemical raw material is widely used in plastic raw materials. Generally, it is related to our daily life to fill it on the tread of tires, as long as it can reduce the resistance caused by rolling and maintain good anti-skid ability.
However, at the same time, due to the adsorption of water on the surface of this substance, it is sometimes difficult to disperse and maintain moisture, which greatly affects the application effect of the product. So, how can effective measures be taken to change this usage method?
The most fundamental way to improve the use of white carbon black is to address its shortcomings in material composition. Since it contains silanol based substances with water absorbing properties, the first step should be to improve its hydrophilicity from the structure of white carbon black. If this structural change is to be designed based on the molecular composition of the substance, it can be changed to hydrophobic or amphiphilic properties. Recently, there is a technology abroad that can narrow the particle distribution, increase the surface area, and present hydrophobic properties.
Secondly, the improvement in the use of white carbon black lies in its contact area with rubber. This can be achieved through the reaction processing of certain chemical substances to change the quantity of hydroxyl groups on its surface, or by adding other chemical substances to change its surface properties. Generally, substances that can undergo chemical reactions with it can be used as substances that change their properties.
