*以下為我司常規規格,可根據客戶要求生產。
儲存條件
■在溫度小于20℃,濕度小于50%可存放90天;小于5℃條件下可存放180天。
■20℃, 50%RH for 90 days ;max 5℃ for 180 days.
■PP應在堆疊室內進行,避免吸濕。
■疊合好的PP與芯板壓合開始時建議最小保持60分鐘的抽真空狀態。
■Stacks must be prepared in lay-up room to avoid moisture absorption.
■Stacks with the core and prepreg is recommended to use the vacuum process for 60min when being heated
■升溫過程
a. 溫度范圍為80-120℃ b. 升溫速率為1.2-2.0℃/分鐘
注意:這些數值僅供參考,當機器和材料結構不同時這些值可能做調整
■為使樹脂固化完全,料溫在180-190度最小保持45分鐘
■為避免板彎翹,冷壓時材料冷卻速率在100℃以上時保持在2.5℃/min以下。
■ Heating
a.Temperature Range=80-120℃ b. Rate:1.2—2.0℃/min
■Note: these values are reference only they may change depending on machine and material structure.
■Temperature of material in 180-190℃ must be held for at least 60mins to make the epoxy solidify completely.
■Cooling rate of material should be kept under 2.5℃/min when the temperature of material is over 100℃,in order to avoid introducing twist.
