细节与部件
介绍
- 气密性：阀门内置密封圈，确保阀门的气密性和完好性
- 聚丙烯多功能阀门：阀门设计合理，气密性好
- 与铝箔、聚四氟乙烯、Tedla、PVDF 采样袋兼容。耐酸碱
- 聚丙烯特性：化学稳定性非常好，除被浓硫酸和浓硝酸腐蚀外，对其他各种化学试剂也比较稳定，但低分子量的脂肪烃、芳香烃和氯化烃会使聚丙烯软化、溶胀、
- 适用温度范围：-30 摄氏度至 +100 摄氏度
使用方法
- 阀门关闭：顺时针旋转到底；
- 阀门开启：从关闭到开启，流量可根据需要调节一圈半；
- 顶盖上有取样孔，内置硅胶垫，用于针式取样，取样精度高。建议更换硅胶垫 15 次左右。
- 特氟龙 fep 薄膜的厚度一般在 0.075mm-0.1mm 左右。根据每批仓库的库存情况，聚四氟乙烯的厚度不同，不同厚度的价格也不同。
- pvf 气体采样袋是 Tedlar 气体采样袋的薄膜，厚度在 0.05mm 左右，耐温在 150 度左右。
- PVDF 薄膜的厚度为 0.05mm-0.075mm，耐温性约为 150 度。交货期取决于仓库中的存货，价格随厚度变化。
配备聚四氟乙烯阀门
使用聚四氟乙烯阀门时，旋钮越过出口时关闭，旋钮打开时与出口平行。聚四氟乙烯阀的耐温性约为 200 度。使用聚四氟乙烯阀门，整个袋子的耐温性与薄膜的耐温性一致。
