Unstable Impact Strength Between Batches of acrylonitrile-butadiene-styrene copolymer Products
Fenómeno del problema
The impact strength test results of different batches of products fluctuate greatly, sometimes qualified and sometimes unqualified.
Análisis de la causa
（1）Raw material batch differences, different molecular weights or rubber contents
（2）Processing temperature fluctuations, different degrees of material degradation
（3）Inconsistent regrind ratios, performance fluctuations
（4）Different internal stresses of products, impact strength differences
（5）Inconsistent test conditions
Solución
（1）Establish incoming raw material inspection standards
（2）Strictly control the processing temperature within the 220-260°C range
（3）Unify the regrind ratio
（4）Optimize the process parameters to reduce internal stress
（5）Unify the test conditions and sample preparation methods
Conclusión clave
Impact strength stability depends on raw material consistency and process stability.
