1. Why choose Xiangxi silicone lubricant for PP engineering plastic?
The main functions of silicone masterbatch lubricants include improving plastic processing fluidity, reducing torque, and reducing equipment wear, making mold filling easier and reducing product defect rates. In addition, it can significantly reduce the coefficient of friction, improve smoothness, improve surface gloss, and enhance the silky texture of the surface. Meanwhile, silicone masterbatch lubricants can also improve wear resistance and scratch resistance.
Compared with traditional silicone oil lubricants, Xiangxi silicone lubricant for PP engineering plastic overcomes the weakness of easy precipitation and has more stable performance. In the processing of PP products, using silicone masterbatch as a lubricant can reduce the injection pressure, shorten the holding time, and lower the mold temperature, thereby optimizing production efficiency.
It should be noted that the amount of silicone masterbatch added needs to be controlled within a certain range. Usually, adding 0.5% can basically solve the problem of difficult demolding of modified PP injection molded products. Excessive addition may affect the performance and quality of the product.
Xiangxi silicone masterbatch,the silicone lubricant for PP engineering plastic have significant advantages in improving production efficiency, optimizing product performance, and reducing production costs, and are indispensable additives in PP product processing.
2.Xiangxi follow strictly the inspection process of silicone lubriant for PP engineering plastic:
Raw material inspection:
Check the purity, moisture content, impurities, etc. of silicone and other additives to ensure that the raw materials meet production requirements.
Conduct performance tests on raw materials, such as melting point, viscosity, stability, etc., to ensure stable raw material performance.
Mixing and preparation:
Monitor the temperature, stirring speed, and time during the mixing process to ensure that silicone lubricant for PP and other additives are evenly dispersed in the PP matrix.
Check the color, odor, and uniformity of the mixture to preliminarily determine its quality.
Particle size inspection:
Use a particle size analyzer to detect the particle size distribution of silicone luubricant for PP and ensure that the particle size meets the product specifications.
Check for particles that are too large or too small, as this may affect subsequent production and use.
Component analysis:
By using chemical analysis, spectroscopic analysis, and other methods, the content of silicone and other additives in silicone lubricant PP is detected to ensure accurate composition.
Check for harmful substances or excessive ingredients.
Test di stabilità termica:
Heat the silicone lubricant PP at a certain temperature, observe its color, morphology, and other changes, and evaluate its thermal stability.
Ensure that silicone lubricant PP is not easily decomposed or produces harmful substances at high temperatures.
Melt Index Test:
Measure the melt index of silicone lubriant PP to evaluate its flowability during processing.
Excessive or insufficient melt index may affect production efficiency and product quality.
Test delle prestazioni meccaniche:
Conduct mechanical performance tests on silicone lubricant PP, including tensile strength, bending strength, impact strength, etc., to ensure that it meets the requirements for use.
Compare the mechanical properties of different batches of products to ensure consistency.
Storage stability test:
Store silicone masterbatch under specific conditions for a period of time, observe its performance changes, and evaluate its storage stability.
Silicone masterbatch with good storage stability can ensure long-term use.
Packaging and labeling inspection:
Check if the packaging of the silicone masterbatch is intact and free from damage, contamination, and other issues.
Check if the product identification is clear and accurate, including product name, specifications, production date, shelf life, and other information.
Recording and reporting:
Record the data and results during the inspection process in detail to form an inspection report.
Determine whether the silicone lubricant PP is qualified based on the inspection results, and propose improvement suggestions or opinions.
Through the above inspection process, it can be ensured that the produced silicone lubriant PP has stable quality and excellent performance, meeting customer needs. Meanwhile, regular inspections and records can also help identify potential issues in a timely manner and make improvements.
