1. The production process of Xiangxi silicone masterbatch on TPR polymer used typically includes:
Vorbereitung des Rohmaterials:
The main raw materials for silicone masterbatch on TPR polymer include chemicals such as silane and methacrylate, as well as auxiliary agents such as solvents, catalysts, and stabilizers. The selection and quality of these raw materials play a crucial role in the quality of the product.
Synthesereaktion:
The synthesis of silicone masterbatch on TPR polymer 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, allowing the polymerization reaction to proceed and generating organic groups.
Nachbehandlung:
The post-treatment of silicone masterbatch on TPR polymer includes removing residual water and impurities from the product to achieve product purity and required degree. The specific steps of post-processing include ion exchange, washing, filtration, as well as testing and analyzing the components.
Verpackung des Fertigerzeugnisses:
After the production of silicone masterbatch on TPR polymer is completed, it needs to be packaged and stored. Common packaging methods include plastic bags, barrels, etc. Different packaging methods should be selected based on factors such as product size, quantity, and purpose. When storing, it is necessary to avoid direct sunlight and humid environments to ensure product quality and stability.
Overall, the production process of Xiangxi silicone masterbatch on TPR polymer is strictly controlled over the selection and quality control of raw materials, as well as the operating conditions of condensation and hydrolysis reactions, to ensure the quality and performance of the product. Meanwhile, post-processing and finished product packaging are also important steps to ensure the quality.
2.How Xiangxi inspect Silicon-Masterbatch on TPR polymer:
The quality inspection of Xiangxi silicone masterbatch used on modified TPR is an important step, which ensures that the performance of the silicone masterbatch meets production requirements and ensures the quality and reliability of the final product. Quality inspection usually includes the following aspects:
Prüfung der körperlichen Leistungsfähigkeit:
This includes checking the physical properties of silicone masterbatch on TPR, such as color, particle size distribution, density, etc. These tests can help determine the uniformity and processing performance of silicone masterbatch.
Chemical composition analysis:
By analyzing the chemical composition of silicone masterbatch on TPR, it is possible to verify whether its chemical composition meets expectations and ensure that there are no residues of harmful substances.
Thermal stability test:
The stability of silicone masterbatch on TPR at high temperatures is an important indicator. By conducting thermal stability tests, the performance of silicone masterbatch during high-temperature processing can be evaluated.
Dispersion test:
Test the dispersibility of silicone masterbatch on TPR material to ensure that it can be uniformly dispersed in the matrix, thereby improving the performance of the final product.
Mechanical performance testing:
Conduct mechanical performance tests on TPR materials with added silicone masterbatch, such as tensile strength, elongation at break, etc., to evaluate the impact of silicone masterbatch on the mechanical properties of the materials.
Aging test:
simulate the aging of the product during use, and check the anti-aging performance of silicone masterbatch to ensure the long-term stability of the product.
Safety performance testing:
For silicone masterbatches that may be used for sensitive applications such as food packaging or children’s toys, safety performance testing is also required, such as migration testing, toxicity testing, etc.
In addition, strict quality control has been carried out for the production process of silicone masterbatch, including quality control of raw materials, monitoring of the production process, and sampling of finished products, to ensure that the quality of silicone masterbatch always meets the requirements.
3.Storage and expiration date:
Lagern Sie das Silicon-Masterbatch ungeöffnet bei Raumtemperatur an einem kühlen und trockenen Ort, die Haltbarkeit beträgt 24 Monate.
