适用于搪玻璃、衬氟塔器内件支撑用途。支撑环接触物料平面均为PTFE材质，通过对聚四氟乙烯板材表面进行奈钠处理工艺并将其加热后通过工装设备使其聚四氟乙烯板材均匀包覆、紧密粘合于钢还外表面， 耐腐蚀性完全由PTFE材质固有特性保证，同时采用足够的钢坯厚度保证其使用的刚度支撑性和使用寿命。产品成型后外表面平整、棱角处圆角过渡，光滑不易粘料，保证了装配于设备后的密封可靠性和易清洁性。衬层厚度通过国家标准高电压电火花试验检测，保证安全性、耐用度。

     It is suitable for supporting the internals of glass lined / Teflon lined column. The plane surface of the support nngcontacting with the medium is made of PTFE. After its surface is treated with Natrium treatment process and heated, thePTFE plate is evenly coated and tightly bonded to the outer surface of billet through tooling equipment. The corrosionresistance is completely guaranteed by the inherent characteristics of PTFE material. At the same time, sufficient billetthickness is adopted to ensure its stiffness, supportiveness and service life. After the product is formed, its outer surfaceis flat, the corners are rounded, smooth and not easy to stick, which ensures the sealing reliability and easy clean ling afterassembly in the equipment. The thickness of the lining layer is tested by the national standard high voltage spark test to ensure safety and durability.
