Dynamic seal mainly refers to the valve stem seal. Polytetrafluoroethylene braided packing: woven thin PTFE tape into packing, which has excellent corrosion resistance and can be used in cryogenic media. For example, in terms of compression bolts, it can be divided into T-bolts (used for low pressure valves with a pres...

Gate valve: A gate valve is a valve whose closing member (gate) moves along the vertical direction of the channel axis. The sealing performance is worse than that of ball valves and globe valves, so it is used in places where the sealing requirements are not very high. The ball valve is mainly used for cutting off, dis...

The mold temperature and the length of the cooling time affect the sticking of the finished product, shrinkage, dimensional tolerance, surface brightness, cycle, etc. The cycle is long and the screw will not retreat. Its function makes the raw material more compact in the transportation and compression. The pressure an...

At the beginning of its investment, pollution control was the top priority. The test results showed that the strength and air permeability of the filter bag were still good after 4 years of use, and its strength was around 300 psi. Reduce user maintenance and operating costs in many ways. The company has advanced equip...

Solvent resistance test: Take 95% medical alcohol cotton and wipe it back and forth 100 times (50 back and forth) with 1 kg of strength on the product coating. There should be no oil stains after wiping.　　 Impact resistance test: Take the sprayed workpiece on the impact resistance test instrument, with a 1kg hamme...

 Reinforcing steel bars should be arranged in the supporting cushions.1.1 When the plate rubber bearing is selected, the maximum bearing capacity of the bearing should be consistent with the reaction force of the bridge fulcrum, and the allowable deviation range should be 10%. The top elevation of the cushion sto...

Take mixing uniformity as the standard. The pressure is 1. The PTFE resin powder should be taken as needed.3 Process three: maturation In order to disperse the extrusion aid to the surface of the powder particles more fully, the mixture must be sealed and allowed to stand at room temperature (23°C or higher) for 5-15 h...

These applications all use the low friction coefficient and non-stick characteristics of the PTFE material, which shows that the tension of the product is reduced to the lowest when the product passes, and the attached dirt is also easy to clean. In addition, if the PTFE material is applied to rollers PTFE coated adhes...
