Creep Deformation of acrylonitrile-styrene-acrylate copolymer Products
문제 현상
The product slowly deforms under long-term continuous load, affecting long-term service performance and dimensional stability.
원인 분석
（1）acrylonitrile-styrene-acrylate copolymer is an amorphous material, and slow creep still occurs below the glass transition temperature
（2）The product is subjected to continuous load, and the longer the time, the greater the deformation
（3）The service environment temperature is high, accelerating creep
（4）The product wall thickness is insufficient, and the stress per unit area is large
（5）The material molecular weight is low, and the creep resistance is poor
해결 방법
（1）Increase the product wall thickness or reinforcing ribs to reduce the stress per unit area
（2）Select a high-molecular-weight grade to improve the creep resistance
（3）Reduce the service temperature, away from the glass transition temperature
（4）Consider the creep amount in the design, and reserve deformation allowance
（5）Add glass fiber reinforcement when necessary
핵심 요약
Creep is the slow deformation of amorphous materials under continuous load.
