What is the maximum temperature that Teflon tape can withstand?

Using glass fiber as the base cloth, coated with Teflon emulsion and dried by mechanical equipment, a new type of composite Teflon glass fiber cloth is made. On the basis of Teflon glass fiber cloth, it is processed and coated with silicone adhesive to make Teflon high temperature resistant tape. Adding other processes in the production process can be made into special-purpose high-temperature resistant Teflon tape, such as Teflon tape with anti-static properties.

Due to different production processes and raw materials, the acceptable Teflon tape max temp is different. The film and glue on the Teflon tape directly affect the temperature effect of the Teflon tape.

The common Teflon high temperature tape can work normally in an environment of 260 degrees and can withstand an instantaneous high temperature of 300 degrees. Some customized Teflon high temperature tapes can work in a high temperature environment of 320 degrees.

Teflon tape is a new type of composite material, which has a wide range of uses. It not only has the strength of glass cloth, but also has the safety of Teflon food grade. At the same time, it has the conditions for working in high temperature environments. More and more industries are in use. Common ones include: packaging, thermoplastics, compounding, sealing heat sealing, electrical and electronic industries. In addition, Teflon high temperature tape can be reused in some special environments, such as in the drum of sizing machine and thermoplastic demoulding field. Teflon tape can be used repeatedly, and it is very convenient to replace.

Description of the tension problem of Teflon mesh conveyor belt

Teflon mesh conveyor belt has been widely used in various transportation industries. It has become a more common conveyor belt. Many users are very comfortable in adjusting the tension of Teflon mesh conveyor belt during use. It is the wrong behavior.

Some users in the daily maintenance, in order to save trouble, directly adjust the tension of the Teflon mesh conveyor belt, which is convenient and easy. However, the situation in which the tension of the Teflon mesh belt is large will greatly reduce the service life of the Teflon mesh belt and the machine equipment, because the tension is too large, resulting in the Teflon grid. The pressure between the conveyor belt and the machine increases, and the degree of wear increases, which is not conducive to daily maintenance and maintenance, and will also affect the quality of the product to some extent.

Some Teflon mesh conveyor belts are used to adjust the conveyor belt very loosely (small tension), which is also wrong, we need to adjust the tension a little, so as to prevent slipping or loosening, but like the above said, and the tension cannot be made too big.

The specific tension control needs to be determined according to the specific environment of the Teflon mesh conveyor belt.

Why some high temperature Teflon adhesive tapes will Degum ?

Because of the price , it is easy for the factory to purchase unqualified Teflon tape, some because of the low requirements for Teflon tape, no abnormalities were found during use. However, some unqualified Teflon tapes may cause residual glue or even overflow glue.

In order to make it clear that these problems occur, we need to understand three points of knowledge about the manufacture of Teflon tape

First, high-temperature Teflon tape is different from Teflon raw tape. The production process of high-temperature Teflon tape is relatively complicated. The raw material emulsion for the production of high-temperature Teflon tape contains chemical components. During production, the staff must strictly control the speed and temperature of the equipment, and the quality of the Teflon tape will be directly affected by the fluctuation.

For example, when the temperature is too high, the produced Teflon tape is prone to overflowing.

Second, the sensitive adhesive used in the production of high-temperature Teflon adhesive tape is cured by baking and heating. If the equipment runs too fast during production, the actual curing of the sensitive adhesive will be insufficient, resulting in the production of special adhesives. It is common to find that some unqualified Teflon tapes are not sufficiently viscous, which is probably due to this problem.

Third, the Teflon tape produced from the coating machine is only a semi-finished product. In order to fully combine the glue and the high-temperature Teflon cloth, it needs to be left alone for 2 to 3 days to let the glue fully cure in a natural state. After curing, the high temperature Teflon adhesive tape will be cut through the equipment.

If the factory floor management of high-temperature Teflon tape is not standardized, or if unqualified raw materials are purchased in order to save costs, the resulting of high-temperature Teflon tape is likely to have insufficient viscosity .

As a factory specializing in the production of high-temperature Teflon adhesive tape, we believe that “there are no cheapest products, only the most suitable products.” The temperature that high temperature Teflon adhesive tape withstands when using is different, the corresponding production cost is also different. When purchasing high-temperature Teflon tape, you must understand your needs. Don’t blindly choose the cheapest Teflon tape, but choose the most suitable Teflon tape.

For all questions about high temperature Teflon adhesive tape, please contact us at info@jiujiangptfe.com , our engineers will reply to you within 24 hours.

Reasons for Teflon mesh conveyor belt slippage

Teflon mesh conveyor belt has been gradually applied to a wide range of applications, and its ultra-high performance has been highly praised by users. However, the Teflon mesh belt will also have some slippage during operation, so these slips will occur. What are the main reasons for the phenomenon? Let’s take a closer look:

The initial tension is too small: the tension of the Teflon mesh conveyor belt leaving the drum is insufficient to cause the conveyor belt to slip. This situation usually occurs at the start-up. The solution is to adjust the tensioning device and increase the initial tension.

The tail roller bearing is not damaged or the upper and lower roller bearings are not damaged. The cause of the damage is that there is too much floating in the tail, and there is no timely repair and replacement of parts that have been damaged or inflexible, causing the resistance to increase and causing slippage.

The start speed is too fast and can form a slip: at this time, it can be started slowly. Or after jogging twice and then starting, it can also effectively overcome the slip phenomenon.

The friction between the drive roller and the Teflon conveyor belt is insufficient to cause slippage. Most of the reasons for slippage are water on the conveyor belt or wet environment.

Teflon products is waterproof but can not be soaked in water for a long time

Teflon coated fiberglass fabric and Teflon adhesive tape are both waterproof. However, is it possible to soak the Teflon product in water for a long time?

Jiujiang PTFE reminds everyone that when using Teflon products, it is important to note that Teflon series products are not suitable for long-term immersion in water. Otherwise, its service life will be greatly reduced.

First of all, Teflon coated fiberglass fabric is made of glass fiber fabric impregnated with Teflon emulsion. Glass fiber fabric will be soft in water and its strength will decrease. This requires us to pay attention to the fact that Teflon tape and Teflon coated glass fabric are waterproof, but not suitable for long time in the water. The Teflon mesh belt product is also the same, because the Teflon mesh belt is also made of fiberglass mesh impregnated with Teflon emulsion and then dried. The silicone pressure sensitive adhesive on the back of the Teflon tape is also weakened by the long-term action of water. Silicone pressure sensitive adhesive contains organic solvent toluene, which will also reduce the viscosity of silicone pressure sensitive adhesive under the action of water, and finally have a great impact on the quality of Teflon tape products.

Therefore, waterproofing is not necessarily suitable for long-term soaking in water. Customers must be aware that the service life in water is very different from the service life not in water. Before choosing Teflon products, we must consult the manufacturer, carefully understand your own use environment, accurately select and grasp the replacement cycle of the product.

The same and the difference between Teflon and PTFE

PVDF is polyvinylidene fluoride, which is a little worse than F4 and F46. It has low temperature resistance and poor corrosion resistance (price is much cheaper than F4 and F46).

PTFE (F4) is polytetrafluoroethylene, which has good temperature resistance and corrosion resistance. It can withstand the corrosion of any medium. The color is absolutely white. It is generally used for lining fluorine pipes, valves, seals, bars, etc.

FEP (F46) is polytetrafluoroethylene propylene, the color is transparent, corrosion resistance is equivalent to PTFE, generally used for lining fluorine pump or perfluorinated pump.

PFA tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer (also known as: perfluoroalkylated, soluble polytetrafluoroethylene)

F4+F46=F50 is a fluoroplastic alloy. This material is also often used in fluoroplastic pumps. They are used together to increase wear resistance.

The chemical properties of PFA FEP PTFE are similar, but FEP can only be used below 200 degrees, and PTFE cannot be injection molded.

Teflon English full name Polytetrafluoroethylene, referred to as Teflon, PTFE, F4

Teflon is divided into PTFE, FEP, PFA, ETFE basic types:

Teflon PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260 ° C, with a maximum operating temperature of 290-300 ° C, very low friction coefficient, good wear resistance and excellent chemical stability.

Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a non-porous film. It has excellent chemical stability and excellent non-stick properties. The maximum operating temperature is 200 °C.

Teflon PFA: PFA (perfluoroalkylated) non-stick coating melts and forms a non-porous film during baking, just like FEP. The advantage of PFA is that it has a higher continuous use temperature of 260 ° C and stronger toughness. It is especially suitable for use in the field of anti-adhesion and chemical resistance under high temperature conditions.

Teflon ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene. It is the toughest fluoropolymer and can form a highly durable coating with excellent chemical resistance and can be used at 150 ° C. Work continuously.

How does the Teflon mesh conveyor belt run on the dryer?

The principle of drying the material on the dryer

1.The staff puts the material into the inner layer of the rotary drum, the material is continuously picked up and scattered under the inner propeller to complete the heat exchange.

2.The material moves to the other end of the inner layer and enters the middle layer, In the middle layer, the material will be continuously pushed in continuously, which absorbs the heat of the inner roller and absorbs the heat of the middle roller while extending the drying time, the material arrives in the best dry form here.

3. Drying the material to the other end of the middle layer and falling into the outer layer. When the material is in the outer layer of the drum, the material that has achieved the drying effect will quickly travel out of the drum under the action of hot air. The wet material that has not reached the drying effect cannot travel fast due to its own weight, and the material that cannot be quickly traveled is sufficiently dried in the rectangular copy board, thereby completing the purpose of drying.

The heating plates for drying by the dryer are generally three groups, and each group consists of four, five, and six heating plates.

In order to achieve the best temperature for the drying effect, we must do the following in its settings:

  • To ensure the solidification of the paste, and at the same time adjust the moisture content of the corrugated board, the two can not be neglected.
  • According to the water content of the single-faced corrugated board, the pressure reducing valve can be adjusted at any time to make the dryer reach the appropriate temperature, which not only ensures the solidification of the paste, but also ensures that the moisture content of the final formed corrugated board is moderate.
  • The length of the dryer cooling section also has an inevitable effect on the moisture content of the board. When the cooling section is too short, the water cannot be volatilized in real time. At this time, it is necessary to increase the amount of air supplied by the department to achieve the purpose of drying.
  • In the setting adjustment, it is guaranteed that the dryer does not stop working. When the water content is too high, the speed is slowed down, and when the water content is too low, the vehicle speed is increased, thereby ensuring the use of the industrial food conveyor belt dryer.
