適用于搪玻璃、襯氟塔器內件支撐用途。支撐環接觸物料平面均為PTFE材質，通過對聚四氟乙烯板材表面進行奈鈉處理工藝并將其加熱后通過工裝設備使其聚四氟乙烯板材均勻包覆、緊密粘合于鋼還外表面， 耐腐蝕性完全由PTFE材質固有特性保證，同時采用足夠的鋼坯厚度保證其使用的剛度支撐性和使用壽命。產品成型后外表面平整、棱角處圓角過渡，光滑不易粘料，保證了裝配于設備后的密封可靠性和易清潔性。襯層厚度通過國家標準高電壓電火花試驗檢測，保證安全性、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.
