Stainless Steel Lined PTFE Storage Tanks, Plate Lined PTFE Storage Tanks, and Tight Lined PTFE Storage Tanks

Pre-activated or adhesive glass fiber cloth-coated PTFE boards are coated with an adhesive, while the steel shell of the equipment undergoes Sa2-grade sandblasting and cleaning with a detergent. The adhesive is then applied, and the PTFE boards are bonded to the steel body using vacuum lining technology, capable of withstanding negative pressure up to -0.095MPa. The thickness of the lining material is selected based on the specific application requirements of the user. This technology is not limited by the size of the manufacturing equipment and also addresses the challenges of cleanliness and temperature in the chemical and electronic chemicals industries. It features excellent resistance to penetration, a smooth and shiny surface, low friction coefficient, non-adhesiveness, and a long service life.

Board Filler Materials and Characteristics
PTFE and PFA imported sheets are produced by the European Fluoroplastic Company using extrusion technology, with a standard thickness of 3mm. The sheets feature a smooth and even surface, high density, consistent thickness, and widths up to 1.2 meters, lengths of 25 meters. Compared to traditional panel-style sheets, they can reduce weld seams.

Differences Between Imported and Domestic PTFE Sheets
Imported PTFE sheets are manufactured in high-grade cleanrooms, with cleaner levels than domestic sheets and thicker corrosion resistance than domestic PTFE sheets.
The EU's PTFE has developed over nearly half a century, with its production processes and techniques being more reasonable and its experience richer than domestic boards. This is mainly reflected in the well-balanced density (2.15-2.2g/cm³) and thickness of the boards, which, while effectively implementing corrosion prevention, does not unnecessarily increase the board thickness, thereby affecting the difficulty of the lining.
The back activation processing technology for PTFE sheets in the EU is among the best globally. The quality of the activation directly impacts the bonding strength of the sheets. The bonding strength of imported PTFE sheets reaches -0.05 Mpa, which is unattainable by domestic sheets.
