Teflon high temperature tape is made of high-quality glass fiber cloth, coated with PTFE resin on the surface, and coated with organic pressure-sensitive silica gel on one side to make high-quality Teflon high-temperature resistant tape.In order to avoid this phenomenon, it is necessary to operate correctly and import raw materials in production.

But glue residue phenomenon is a common phenomenon.

After the Teflon tape is subjected to high temperature, there will be residual glue, glue overflow, degumming and other phenomena. Through close observation, it will be found that there are tiny residues, which have a great impact on production.If the temperature is too high and it is not within the scope of the process requirements, there will also be residual glue phenomenon, and you should check whether the temperature sensor is normal; however, the Teflon high temperature tape product itself has quality problems, and the pressure is not strictly followed in the coating production process. The baking data of the sensitive adhesive is heated and cured, and the curing time is not enough or the coating line speed is too fast, which will cause the glue, the primer glue, and the substrate to be unable to combine the components;When the Teflon tape is formed, the semi-finished roll material needs to stand for 2-3 days before the tape can be re-rolled, and then cut and used, mainly to fully combine the glue and the substrate, so that the glue can be in a natural state Fully cured, if the rewind tape is slit without complete curing, residual adhesive will appear.

If there is residual glue phenomena in the production process, the problematic workpiece should be taken out and placed separately. In order to avoid such phenomenon, the online products should be checked more intensively, and analyzed through a period of time or a certain number of bad statistics. The percentage of residual glue rate should also be checked according to the actual situation of this batch of tapes to find out the root cause of the problem, so that similar phenomena will not occur in the production process.

Teflon High-temperature Tape

Therefore, the production process of Teflon tape should also be strictly carried out. Once a problem occurs, it will cause waste of resources and delay production.

It can be seen that the phenomenon of residual glue in Teflon tape is very common. The reason may be the problem of raw materials, or it may be a problem in production. In addition, it may be that the temperature is too high during use, which exceeds the high temperature Teflon tape can withstand.

If there is a problem with the quality of the tape, the customer should not panic and contact the manufacturer to solve this problem.

  • First, confirm whether the high temperature resistance data of the Teflon tape in use meets the production requirements, usually requiring a temperature resistance of 210 degrees to 260 degrees.
  • Whether the temperature data of the production line is within the range of process requirements, whether the temperature is too high, check whether the temperature sensor is normal.
  • In view of the quality problems of the Teflon tape product itself, whether the Teflon tape is heated and cured in strict accordance with the pressure-sensitive adhesive baking data during the coating production process, the curing time is not enough or the coating line speed is too fast, it will As a result, the glue, primer glue and substrate cannot be combined.
  • After the Teflon tape is coated, the semi-finished product should be left for 2-3 days before rewinding and slitting. The purpose is to fully combine the glue with the substrate, and the glue will be completely cured in a natural state;

As a factory specializing in R&D and production of Teflon coated fiberglass fabric, our engineers often receive inquiries from customers and colleagues as to why some Teflon coated fiberglass fabric has insufficient strength.

The use of Teflon coated fiberglass fabric with insufficient strength may tear, which directly affects the use of the product. We have sorted out the following aspects about the reasons that affect the strength of Teflon coated fiberglass cloth. You can refer to these reasons for improvement and avoid the production of insufficient strength Teflon coated fiberglass fabric in the process of producing Teflon coated fiberglass fabric.

Reasons that affect the strength of Teflon coated fiberglass fabric

1.The strength of glass fiber yarn directly affect the strength of Teflon coated fiberglass cloth.

Teflon coated fiberglass fabric is based on glass fiber cloth. The strength of glass fiber cloth directly determines the strength of Teflon coated fiberglass fabric, and the strength of glass fiber yarn determines the strength of glass fiber cloth.

Before the glass fiber yarn is woven into the glass fiber cloth, there will be a desizing process. This process will affect the combination of the finished glass fiber cloth and the Teflon emulsion. If the desizing is abnormal, it will affect the adhesion of the Teflon coating.

In the selection of raw materials, we must buy qualified glass fiber cloth.

2. Quality control in the production process of Teflon coated fiberglass fabric affects the strength of the coated fiberglass fabric.

In the process of combining glass fiber cloth and Teflon emulsion, the glass fiber cloth is in a high temperature environment. It is necessary to have enough temperature to ensure the full combination of Teflon emulsion and glass fiber cloth. It is also necessary to prevent damage to the glass fiber cloth caused by excessive temperature.

If abnormal production equipment or improper operation by personnel causes the high temperature to last too long, it may affect the hardness and strength of the glass fiber cloth, and the strength of the produced Teflon coated fiberglass fabric will be unqualified.

The temperature change adjustment and time control of the drying process are very important.

3.The packaging, transportation and storage of the finished Teflon coated fiberglass fabric will affect the strength of the Teflon coated fiberglass fabric.

Whether it is packing, transportation, or storage, the operator must handle it carefully to prevent creases on the surface of the Teflon coated fiberglass fabric. Once there are creases, the abnormal quality of the Teflon coated fiberglass fabric during repeated use is almost all due to the existence of the crease, and the Teflon coated fiberglass fabric tears from the crease.

The above is a summary of our engineers from the insufficient strength of Teflon coated fiberglass fabric in the market. If you have any abnormalities in the process of using Teflon coated fiberglass fabric, please contact us at infocorefrp@gmail.com, and we also provide Free samples of Teflon coated fiberglass fabric, Teflon conveyor belt, Teflon tape and other products.

Preparation method of PTFE modified film suitable for solar cell protective film, adding surfactant, epoxy resin and polytetrafluoroethylene resin powder to kerosene in sequence to obtain a mixture; stirring the mixture at constant temperature to obtain the second mixture; Then sequentially matured, formed, heat treated, cold treated, sliced, modified. The formed PTFE modified film suitable for solar cell protective film has a light transmittance of more than 90% at 400nm to 750nm, which can fully meet the performance requirements of photovoltaic vehicles for the film before packaging. It has a long service life and is resistant to friction and wear, which aso has excellent mechanical properties.

In the context of global warming and the deterioration of the ecological environment, looking for alternatives to fossil energy and improving the energy structure have become the focus of attention of all countries. Among the many clean energy alternatives, solar energy is considered to be one of the most promising energy sources in the future for its clean, safe, and abundant resources, and it has received great attention and support from countries all over the world.

At present, the most representative of the development and utilization of solar energy is the solar cell, which is a self-produced and environmentally friendly clean energy source. It generates negatively charged electrons and positively charged holes correspondingly through the sensitivity of semiconductor materials to incident light. Then, due to the potential difference or charge concentration difference, the electrons move to the negative electrode and the holes move to the positive electrode, and then generate electricity. Generally speaking, solar cells are placed outside, the outer wall or roof of the object is directly exposed to sunlight to maximize its efficiency. Since solar cells are exposed to the external environment for a long time, strict requirements are put forward as a protective film for protecting solar cell modules, such as low linear expansion coefficient, excellent air tightness, high light transmittance, and excellent surface smoothness resistance and excellent heat resistance and chemical resistance.

Traditional solar cell protective films such as glass substrates are easily broken due to their low shock resistance, high density and heavy weight, and are not suitable for use as protective films for solar cells in photovoltaic vehicles. The main use of ethylene tetrafluoroethylene copolymer (ETFE) , due to the high molecular polymer has vinyl, its chemical activity is relatively high, and its weather resistance and scratch resistance are relatively poor.

A composite film for the backplane of solar photovoltaic cell modules and its preparation method is widely used in the industry. It is composed of seven layers of materials. Among them, the polytetrafluoroethylene film is subjected to low-temperature plasma surface treatment to generate hydrophilicity on the upper and lower surfaces of the film. Therefore, the tackiness of the surface of the PTFE film is greatly enhanced, which makes it have good bonding performance with the PET film layer, and also enables the backplane composite film to be more stably fixed to the solar photovoltaic cell film, improve the overall stability of solar photovoltaic cells.

The above research provides a cheaper and easily available material for solar cell protective film-polytetrafluoroethylene, but the processing method for PTFE film is only applicable to the back sheet composite film, because the back sheet does not need sunlight, so the transparency is not The high PTFE film can meet the needs of the back sheet film, but it is not suitable for the front film of the solar cell. The reason is that the solar cell uses the sunlight to generate electricity, and the intensity and amount of the incident light directly affects the solar energy. The performance of the battery, the PTFE film used in the above scheme is poor in light transmission, its sunlight is less, and the solar energy conversion utilization rate is too low.

Polytetrafluoroethylene is used as the raw material for preparing solar cell protective film. Polytetrafluoroethylene (PTFE) is a white wax-like linear crystalline thermoplastic. Since the fluorine atom linked by each carbon atom in the molecular structure is completely symmetrical in conformation, there is no hydrophilic group and photosensitive group in the molecule, and its moisture resistance and weather resistance are good. The bond energy of the CF bond is high and stable, and the fluorine atom is more stable than hydrogen. The van der Waals radius of the fluorine atom is larger than that of the hydrogen atom, so the complete substitution of the fluorine atom makes the PTFE form a spiral structure. The inert spiral-shaped perfluorinated “cylindrical shell” combined with the non-polar and crystalline structure of the polymer, PTFE has excellent chemical resistance, most non-fluorinated strong acids, strong bases, strong oxidants and salts have no effect on them .

Using kerosene as the solvent of the second mixture is conducive to the optimal arrangement of polytetrafluoroethylene molecules and improving the film-forming effect. Using epoxy resin as the bisphenol epoxy resin is conducive to the curing of the film after film formation. And after the raw materials are evenly mixed, the slow stirring is carried out again, during which there is a transformation of cold and hot states, which promotes the optimization of the molecular chain structure. The transparent front film made of polytetrafluoroethylene as the main material obtained by curing, isostatic molding, high temperature heat treatment, low temperature heat treatment and other modification methods has good light transmittance, and the light transmittance can reach 400nm to 750nm reaches more than 90%, it can fully meet the performance requirements of photovoltaic vehicles for the front film of the packaging, with long service life, resistance to friction and wear and scratches, and excellent mechanical properties.

By adopting a specific temperature program method, it is more helpful to improve the setting performance of the molecular structure and improve the molecular structure. Plasma is used to modify the slices, and its effect is to increase the surface activity of the slices to enhance their bonding strength and achieve strong adhesion between the PTFE film and the photovoltaic cell.

In many places in life, conveyor belts are used for cargo transportation, common minerals, cement, metallurgy, conveyor belts are also used on various logistics workbenches, Some special fields such as food, medicine, and some high-temperature environments have special requirements for conveyor belts.

Safety is at the core of the food industry, and many companies are using stainless steel conveyor belts. In the working environment of some food conveyor belts, stainless steel conveyor belts are not the best choice. Relatively speaking, Teflon conveyor belts are better.

The difference between Teflon conveyor belt and stainless steel conveyor belt

Teflon conveyor belt is a new type of composite material made of glass fiber cloth coated with Teflon resin and processed by mechanical processing. Teflon conveyor belts are divided into two categories with mesh and no mesh. The specific model is generally defined according to the size of the mesh and the thickness of the conveyor belt.

The stainless steel conveyor belt is made of stainless steel. The stainless steel conveyor belt has mesh holes on it, which has good ventilation effect.

Compared with stainless steel conveyor belts, the biggest advantage of Teflon conveyor belts is that they are non-sticky and resistant to strong acids and bases. The biggest disadvantage is that the load of Teflon conveyor belt is lower than that of stainless steel conveyor belt, and the service life of Teflon conveyor belt is lower than that of stainless steel conveyor belt.

Teflon conveyor belt has anti-corrosion resistance and very excellent non-stick characteristics, especially suitable for food conveyor belt. At the same time, Teflon conveyor belt can also work continuously at 260 degrees Celsius. In the working environment, the Teflon conveyor belt is easy to replace, and the price of food-grade Teflon conveyor belt is far lower than the price of food-grade stainless steel conveyor belt. So the baking industry usually uses Teflon conveyor belts instead of stainless steel conveyor belts.

However, because Teflon conveyor belts are not as strong as stainless steel conveyor belts, stainless steel conveyor belts are usually used when harvesting cereals and vegetables on the farm. When there is no need for the two characteristics of non-stick and food grade, stainless steel conveyor belts or other material conveyor belts will be used.

In general, when the conveyor belt has food grade safety requirements, you can consider using Teflon conveyor belt. If you still need non-stick performance, then Teflon conveyor belt will be your first choice.

As a factory specializing in the production of Teflon conveyor belts, we produce and sell various types of Teflon conveyor belts.
