PC Electrical Insulation Applications
문제 현상
[Problem Phenomenon] Electrical insulation parts require high CTI and heat resistance
원인 분석
PC has good electrical insulation and relatively high CTI, used for electrical insulation parts and connectors; flame retardant grades are superimposed; heat resistance adapts to temperature rise; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
해결 방법
Select PC for insulation parts; CTI according to voltage level; select flame retardant grades for flame retardant requirements; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
핵심 요약
PC has good electrical insulation; CTI and flame retardancy are selected as needed; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
