Manufacturing process of polytetrafluoroethylene gasket
- 2019-11-21-

Today, I would like to introduce you to the PTFE gasket . This product may seem strange to you by its name, but it is right by our side.

We take you through a variety of aspects to understand this product.

First, the production process is divided into seven steps:

1. Raw material preparation; ingredients: pure F4 products, raw resin F4 fine resin, mashed, sieved

2, mold preparation: wipe clean with alcohol, no rust, no attachments in the mold

3.Weighing, according to the formula G = PV

4. Feeding: F4 resin is evenly distributed on the entire pressing surface.

5. Pressing: Calculate the gauge pressure of the press according to the formula, and set the gauge pressure of the press. To suppress

6. Stripping and trimming: take the semi-finished product out of the mold, trim its surface to make the surface flat and the edges neat. Ready to shape.

7. Sintering: Put the semi-finished product into the sintering furnace slowly, put in the appropriate amount, heat up to about 390 degrees for one hour, and then maintain the temperature for one hour. After the molding, the temperature will begin to decrease. After about four hours, the temperature will reach the indoor temperature for the finished product Out of the oven, and finally finalized.

It can be seen that the processing technology is complicated. In fact, there are many applications of polytetrafluoroethylene as a sealing material. Because of its high corrosion resistance, stable physical properties, and high and low temperature resistance, it has achieved its good sealing performance and has been widely used in the petroleum, chemical, pharmaceutical, power, and steel industries. Suitable media include water, oil, acid solution, alkali solution and almost all chemical components.

This product is durable and reliable, making it the most popular product in the industry. In fact, the raw materials of this product are not limited to gaskets, but can also be used in packing and soft packing, which are very practical.
