polytetrafluorethylene

Made of shaping Polytetrafluorethylene Resin by moulding in ordinary temperature then through high heat sintering.

将聚四氟乙烯树脂在常温下用模压法成型高温烧结制成。

Sample was digested in polytetrafluorethylene sealed vesssle by nitric acid-perhydrol or high chloric acid-perhydrol, Hg As Pb were simultaneously determinated by ICP-AES.

采用高压溶样弹，将样品用硝-过氧化氢或高氯-过氧化氢溶解，用ICP-AES法对连续测定。
