Introduction: With the continuous progress of society and the shortage of product resources, more and more companies are beginning to recycle and use resources. In the recycling and utilization of equipment, they will be applied to the chemistry of strong acids and alkalis. Products, some recycled products can only be extracted at high temperatures. We recommend 10 tons of steel-lined PTFE high-temperature storage tanks with steel-lined PTFE tanks and steel-lined F4 tanks. With the continuous progress of society and the shortage of product resources, more and more companies are beginning to reclaim and utilize resources. In the recycling and utilization of equipment, they will be used in a large number of chemical products with strong acids and alkalis. Some recycled products can only be extracted at high temperatures. This has caused great problems for material selection. On the one hand, it is strong acid, it is highly corrosive, and on the other hand it is high temperature. How to choose the better product in mind? Here I introduce in detail the steel lining PTFE storage tank and steel lining F4 tank product of our company's steel lining PTFE high temperature storage tank, hoping to help you solve the problem of material selection.

First of all, to understand the use of PTFE in steel-lined PTFE high-temperature storage tanks lined with PTFE tanks and F4 tanks lined with steel. The full name of tetrafluoroethylene is PTFE. Polytetrafluoroethylene (abbreviated as F or PTFE), commonly known as plastic king, is one of the most corrosion-resistant substances in the world today. It is an ideal material for manufacturing chemical anti-corrosion equipment. The steel-lined PTFE storage tank processed by our company is a process in which PTFE powder is processed and cut. The PTFE powder is processed into 3mm PTFE plates. The temperature range of this material itself is -30-250°C. However, when the PTFE plate is covered in the tank, glue is needed. We know that the glue is not resistant to the high temperature. The maximum is 120°C. Above this temperature, the PTFE plate will not be damaged, but The PTFE plate will fall off from the tank and will affect its use.
Simply put, the construction process of steel-lined PTFE high-temperature storage tank steel lining PTFE tank products:
1. Tanks are shaped according to drawings;
2. Sand blasting and derusting treatment according to Sa2.5 grade requirements in the storage tank;
3. Sodium treatment of PTFE plates;
4. Brush the glue twice on the surface of the PTFE plate and the tank and make sure to brush evenly;
5. Apply a naturally air-dried PTFE plate over the surface of the tank;
6. V-shaped groove on the straight seam and the annular seam between the PTFE plate and the plate;
7. First welding with a 5mm PFA electrode in the V groove;
8. Flatten the welded round belt with the PTFE plate;
9. Then use 14mm PFA electrode to weld it again.
10. Use 15Kv electric spark detector to check the equipment as a whole;
11. Finished product storage.
