What is Heat Shrinkable Tube structuring, and how to solve structuring?

What will be the consequences of the structuralization of Heat Shrinkable Tube? The production process of Heat Shrinkable Tube is a process that will change. Now the society is developing faster and faster, and the further progress of the times has also resulted in the development of a market-oriented economy. More and more people are engaged in the pipe business, but if the pipe business is not perfect, there will be many problems, among which the pipe structure is an important problem. So, why does the structure appear in the production process, what is the structure of the Heat Shrinkable Tube, and how to solve it after it occurs.

Generally speaking, the production structure of Heat Shrinkable Tube is to process natural Cable Sleeve, process them according to the required formula, and finally add synthetic agents and other materials through the synthesis of rubber mixers and abrasive tools, and finally form one by one. tubing. However, pipe structure may appear when the general factory produces pipes. The structuralization of the pipe is that the Cable Sleeve with weak white carbon black will harden during the storage process during the production process, which will reduce the plasticity of the rubber and thus lose the processing performance. This phenomenon is called Structuring for tubing.
One is to add structural control agent, silicone oil or silane, silicone resin, etc. with active groups, which is the most commonly used method in production. For example, adding a certain amount of hydroxyl silicone oil, silazane,can have a good structural control effect; the mechanism is that substances such as silicone oil with active groups undergo condensation reactions with active hydroxyl groups on the surface of silica, thereby Interaction between silica and raw rubber is prevented.
2. Surface treatment of silica, such as silane coupling agent, hexamethyldisilazane, etc., can also prevent the structuring of silica gel rubber. The mechanism is that the surface of silica has been wrapped by coupling agent or silazane, and the surface active groups of silica have been shielded, thus preventing the interaction between silica and raw rubber.
