介绍:
PFA结晶料,吸湿小。可采用通常得热塑性塑料得加工方法加工成制品。
PFA流动性差,极易分解,分解时产生腐蚀气体。宜严格控制成型温度不要超过475度,模具应加热至度,浇注系统对料流阻力应小。
PFA是半透明粒料,注塑、挤出成型。成型温度度,475度以上容易引起变色或发生气泡。并注意脱模会较困难。
详解:
, Madame de Villefort came to her assistance. "Retire, Valentine," said she; "you are really suffering, and these ladies will excuse you; drink a glass of pure water, it will restore you." Valentine kissed Eugenie, bowed to Madame Danglars, who had already risen to take her leave, and went out.

Meanwhile, Valentine, in a sort of excitement which she could not quite understand, had crossed Edward's room without noticing some trick of the child, and through her own had reached the little staircase. She was within three steps of the bottom; she already heard Morrel's voice, when suddenly a cloud passed over her eyes, her stiffened foot missed the step, her hands had no power to hold the baluster, and falling against the wall she lost her balance wholly and to
