Hazy whitening appears on the surface of CAB transparent products
문제 현상
Hazy whitening appears on the surface of CAB transparent products, transparency significantly decreased
원인 분석
CAB moisture content exceeds standard, vaporizing during processing causing micro-bubbles
Processing temperature low, melt fluidity insufficient, poor surface replication
Mold surface polishing insufficient
Cooling too fast, surface condensation fogging
CAB degradation produces low-molecular substances that volatilize and condense
해결 방법
Fully dry CAB, moisture ≤0.02%
Appropriately increase the processing temperature to the higher value of 170-230°C
Polish the mold to mirror level
Adjust the cooling rate
Control temperature to avoid degradation
핵심 요약
CAB whitening needs to be addressed from drying and temperature
