1.What can solve certain problems during TPU granulation process?
During the TPU granulation process, various quality issues may be encountered. As a functional additive, silicone masterbatch on TPU can be helpful in solving certain problems.
Firstly, silicone masterbatch on TPU can improve the flowability of thermoplastic resin in the molten state, improve the dispersion of fillers, and reduce the energy consumption of extrusion injection molding, thereby improving production efficiency.
If the quality issues that occur during the TPU granulation process are caused by poor fluidity or uneven dispersion of fillers, the addition of silicone masterbatch on TPU may help improve these issues.
Secondly, silicone masterbatch on TPU can also improve the surface smoothness of final plastic products, reduce surface friction coefficient, and improve wear and scratch resistance. If there are problems with TPU granulation products in these aspects, the addition of silicone masterbatch may be helpful.
2. The production process of Xiangxi silicone masterbatch on TPU includes the following steps:
Raw material preparation:
The production of silicone masterbatch on TPU requires the use of various raw materials such as organosilicon monomers, diluents, catalysts, and additives. The selection and quality of these raw materials play a crucial role in the quality of products, therefore, high-quality raw materials should be selected and subjected to strict quality testing.
Proportioning:
Scientifically and reasonably proportioning different raw materials to ensure that the produced silicone masterbatch on TPU achieves the best performance parameters.
Mixing:
Put different types of raw materials into a mixer for mixing, stirring, and continuous constant temperature to achieve better reaction results.
Synthesis reaction:
The synthesis of silicone masterbatch on TPU is mainly achieved through hydrolysis condensation reaction. In the reaction, raw materials such as silane and methacrylate first undergo efficient condensation reactions with polyol molecules, producing a siloxane skeleton. Then, an organic acid catalyst is added for hydrolysis reaction, generating organic groups and enabling polymerization reaction to proceed.
Post treatment:
Remove residual water and impurities from the product to achieve purity and required degree. Post processing includes steps such as ion exchange, washing, filtration, as well as testing and analyzing components.
Tablet pressing:
Place the mixture into a tablet press for tablet pressing treatment. Appropriate parameters such as temperature, pressure, and time need to be set in the tablet press to ensure the stability and controllability of the quality of the prepared silicone masterbatch on TPU.
After completing the above steps, the production of silicone masterbatch on TPU is completed. Silicone masterbatch has excellent properties such as heat resistance, low temperature resistance, chemical resistance, and weather resistance, and is widely used in various fields such as aerospace, aviation, electronics, and machinery.
3. Silicone masterbatch plays an important role in the TPU granulation process:
Enhanced anti-abrasion:
Silicone masterbatch can effectively improve the wear resistance of TPU materials, increase surface hardness, and make the final product have better durability during use.
Improving surface properties:
Silicone masterbatch can improve the surface properties of TPU materials, making the surface smoother, reducing friction coefficient, and improving the appearance quality of products.
Improving processing performance:
The addition of silicone masterbatch on TPU helps to improve the flowability of TPU materials in the molten state, promote the dispersion of fillers, reduce energy consumption in extrusion and injection molding, and improve production efficiency.
Increasing material rigidity:
Silicone masterbatch can enhance the rigidity of TPU materials, improve the structural stability and load-bearing capacity of products.
Improving chemical corrosion resistance: The addition of silicone masterbatch on TPU can also enhance the chemical corrosion resistance of TPU materials, making them more stable in specific chemical environments.
In summary, silicone masterbatch plays a multiple role in improving performance, quality, and processing efficiency in TPU granulation, which is of great significance for optimizing the comprehensive performance of TPU products.
It should be noted that the amount and usage method of silicone masterbatch on TPU should be determined based on specific product performance requirements and process parameters to ensure the quality of the final product.
