High Temperature Teflon Tape Is Applied To The Pulp Drum

Many mortar rollers use Teflon spray processing for convenient use, which can reduce friction and make winding more convenient. But when using, the Teflon spray coating on the drum will wear out, causing abnormal production. If the cost of the scrap roller is too great, and the repair roller is sprayed again, the cost is not low, and the operation is very troublesome.

High Temperature Teflon Adhesive Tape

Now, Teflon tape with release paper can be used instead of Teflon spraying, and Teflon tape can be pasted on the pulp drum, and the effect of Bitter Flon spraying is better.

Compared with traditional spray rollers, the use of Teflon tape is convenient, low technical requirements, and durable.

However, in order to make the service life of the Teflon tape sticking roller longer, pay attention to the following technical points:

  • Clean the surface of the yarn pulp drum that needs to be pasted with Teflon tape. The cleaning agent is best to use alcohol and wipe with cotton sliver. The yarn sizing drum must have a smooth surface, no iron filings, and no other impurities, so that the Teflon tape can better stick to the drum.
  • When the rollers are pasted with Teflon tape, they need to be partially overlapped. Use scissors to cut out the Teflon tape that is about 5CM longer than the required length, and take the cut Teflon tape to the side of the roller to be pasted.
  • Take the Teflon tape to the roller, slowly tear off the yellow release paper, and at the same time, attach the exposed part of the rubber surface to the roller, tear off the tape while attaching it. You can use cloth or newspaper during the attaching process The soft objects are rubbed and flattened at the roller where the Teflon tape has been applied. After the application is completed, make sure that the two sides of the Teflon tape overlap
  • After attaching the Teflon tape, carefully check whether there are small bubbles between the tape and the drying cylinder. If so, you can use a pin or other sharp object to remove the small bubbles one by one and flatten them.

Project aims to realize prepreg substrate materials for automotive applications

DIC announced that its project in partnership with the Fukui Seiren and Fujinsi County Industrial Technology Centre had been selected by the new Energy and Industrial Technology Development Organization (NEDO) as the main research project for the Strategic Innovation Plan for fiscal year 2018. Energy-saving technologies (commercial development phase).The project focuses on the commercialization of fast curing prepreg for the manufacture of carbon fiber composites for automotive applications.

The NEDO program seeks to advance the development of technologies that will contribute to create an energy-efficient economy and society and/or improve the competitiveness of Japanese industry. The program selects and subsidizes technological development project with the potential to significantly reduce energy consumption. (Projects selected in fiscal year 2018 will be subsidized from fiscal year 2018 through fiscal year 2020.)

The project brings individual technologies by three specialists together; DIC’s radical-curing resin (cures in less than one minute at 150°C) that leverages its original polymer design technologies; the Industrial Technology Center of Fukui Prefecture’s tow spreading (processes fiber bundles into flat sheets) and high-speed prepreg processing technologies; and Seiren’s high-quality prepreg processing and quality management technologies. The goal is to develop fast-curing prepreg suitable for mass production that achieves both low production costs and high quality within the world’s shortest production time. The prepreg can also be stored at room temperature.

The project also includes the development of a high-speed manufacturing mass production process for commercialization and mass production of the new prepreg, which reduces the energy consumption required for production and molding and improves vehicle fuel economy by reducing vehicle weight. As a result, the project is expected to yield a 90,000 kl (crude oil equivalent) reduction in energy consumption in 2030.

In recent years, automakers have focused on reducing vehicle weight with the aim of boosting fuel economy. While this trend has driven a steady increase in the use of carbon fiber composite materials in vehicle challenges remain such as the final cost arising from expensive materials and slow molding speeds. DIC, the Industrial Technology Center of Fukui Prefecture and Seiren continue working together to achieve mass production of their new prepreg with the aim of overcoming this challenge and encouraging adoption by automakers. In doing so, the three organizations look forward to realizing a product that helps in further advance the popularity of carbon composite materials.

How to judge the quality of Teflon mesh belt from the senses?

How to Judge the Quality of Teflon Mesh Belt?23

There are many kinds of Teflon mesh belt in the market, but the qualities are mixed, since the differences between different fiberglass meshes the factories used, production technologies and market concepts.

We can visually identify the amount of impregnated Teflon emulsion from the degree of surface smoothness. If no gloss shows, this mesh belt uses less emulsion in order to save costs. On the one hand, the amount of emulsion affects the price. On the other hand it affects the service life of the mesh belt.

From the sense of touch, you can hold the sample and fold it at a 30-degree angle. If there is obvious crease after folding 3-5 times, it means that the curvature of mesh belt is not enough. The length of Teflon meshes is generally dozens of meters. If the sample breaks for a little bit folds, it must not be used on the machine. Conversely, if you fold more than 5 times and it maintains the original hardness and curvature, this mesh belt is qualified.

This material is commonly known as Teflon. And its formal name is polytetrafluoroethylene (abbreviated as Teflon, PTFE,and F4), that also known as the “Plastic King”. It is polymerized by tetrafluoroethylene, and its structural formulas is -[-CF2-CF2-]n-.

High Temperature Resistance——its operating temperature up to 250℃, and can be used long-term in 200~260℃.
Low Temperature Resistance——it has good mechanical toughness, which can maintain a 5% elongation even if the temperature drops to 196℃ ,and it is still soft at-100℃.
Corrosion Resistance——it shows inert to most chemicals and solvents, and can resist strong acid, alkali, aqua regia and a variety of organic solvents.
Climate Resistance——it has the best aging life in plastics.
High Lubrication——it has the lowest friction coefficient (0.04) in solid materials, which is smoother than ice.
Non-adhesion——it has the smallest surface tension in a solid material and does not adhere to any substance.
Non-toxic——With physiological inertia, it can used as artificial blood vessels and organs and implanted in body long-term without adverse reactions.
Aging resistance——it has irradiation resistance and low permeability, so it can maintain the surface and performance even if it has exposed to the atmosphere long-term.
Non-flammability——its limited oxygen index is below 90.
Acid and Alkali resistance——it is insoluble in strong acid, strong alkali and organic solvents (including magic acid, i.e. fluorine antimony sulfonic acid).
Antioxidant resistance——it can be resistant to strong oxidizing agents.
Insulation——it has excellent electrical properties, which is the ideal C-class insulation material. For example, the Teflon that is as thick as the newspaper can block 1500V high pressure. Its electrical insulation is not affected by temperature. The dielectric constant and dielectric loss are very low in the wide frequency range, and the breakdown voltage, volume resistivity and arc resistance are relatively high.
Acid-alkaline-it is neutral.

How to classify Teflon tape according to the degree of high temperature resistance?

Specifically, if the working environment is just up to about 100℃ and the company does not pay much attention to the quality and service life to Teflon tape, the choice of Teflon tape that temperature resistance reaches 260℃ is a waste.

How to classify Teflon tape according to the degree of high temperature resistance?

If the working environment requires that its temperature resistance is up to 180-260℃, then you must choose the 260℃ Teflon tape.

Therefore, domestic customers are generally divided into above two types except the customers who uses imported rape. Most customers, especially end-use customers, will choose the 260℃ Teflon tape taking into account the degree of temperature resistance and service life, so this kind Teflon tape is more popular in the market.

Teflon coating is a unique high-performance coating that combines heat resistance, chemical inertia, excellent insulation stability and low friction, which has the combined advantages that other coatings cannot compete with, and the flexibility it applies allows it to be used in almost all shapes and sizes of products.

Teflon is divided into several basic types as PTFE, FEP, PFA, ETFE.

1, Teflon PTFE: non-stick PTFE (polytetrafluoroethylene) coating can be used continuously in 260 ℃, with a 290-300 ℃maximum temperature, very low friction coefficient, good wear resistance and chemical stability.

2, Teflon FEP: non-stick FEP (ethylene fluoride propylene copolymer) coating melts and forms porous film in baking. It has excellent chemical stability and non-stick characteristics, and the maximum operating temperature is 200℃.

3, Teflon PFA: non-stick PFA (over fluorine alkylation) coating melts and forms porous film in baking. The advantage of PFA is that it has a higher continuous temperature ( 260℃) and stronger toughness, which especially suitable for the high temperature conditions of anti-adhesion and chemical resistance.

4, The Teflon ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene. That is the toughest fluorine polymer that can form a highly durable coating with excellent chemical resistance, and it can continuous operate at 150 ℃.

After Teflon coating, it has the following characteristics:
1 Non-adhesion: almost all substances are not bonded with Teflon coating even if the coating is very thin membrane.
2 Heat Resistance: Teflon coating has excellent high and low temperature resistance characteristics. It can withstand high temperature to 300 ℃ in short time. And it can be used continuously between 240℃~260℃ with significant thermal stability. What’s more, it will not embrittle at freezing temperature, and will not melt in the high temperature.
3 Sliding: Teflon coating has a low friction coefficient. The friction coefficient changes when the load is sliding, and the coefficient is 0.05-0.15.
4 Moisture Resistance: Teflon coating surface does can keep free from water, oil and solution when operating. If it is sticky a small amount of dirt, simple wipe can removed it. Short downtime can save working hours and increases productivity.
5 Wear Resistance: Teflon coating has excellent wear resistance under high load. And, it has the dual advantages of wear resistance and non-adhesion under a certain load.
6 Corrosion Resistance: Teflon is almost immune from drug erosion, so that it can protect parts from any kind of chemical corrosion.

How to test the viscosity of Teflon tape?

Because there are many suppliers in current market, Teflon tape’s quality is uneven. Most of customers pay attention to its sticky. For example, customers’ will is to use their own hands to test stickiness once getting a roll of tape. In fact, they certainly cannot test for the moisture, booty on their hands. We use steel to do the test in Teflon production, and the surface of the steel need to be very clean, which is a more formal test method. But many customers cannot do such test for the conditions limits. The best way should be glue itself with the face of adhesion, and then pull open. The greater the intensity of the pull, the greater the viscosity.

How to test the viscosity of Teflon tape?

Teflon tape has many characteristics like anti-adhesion, high temperature resistance, corrosion resistance and so on, so it is widely used in various industries. Teflon tape has a wide variety, different colors, and different price according to different quality. Today, our Taixing, Yong Sheng fluorine Plastic Products Co., Ltd. specializes in the production of Teflon tape. At present, the thickness of Teflon tape is 0.13mm-0.3mm. Their color has coffee, blue, black, and white. And the black is divided into anti-static and non-antistatic. The price is RMB 40 yuan to 60 yuan. Our products are very popular since the listing.

Let us talk about that how long should the Teflon tape to be used, that the problem has been bothering a lot of customers. After testing and technical discussion, we found that the good-quality tape almost will not happen residual glue degumming in half a year. And the slightly low-quality tape that adhesive is not pure will have residual glue when using after half a year. Even in the moment of ripping off, glue has been falling off.

Some customers would like to order the amount of one year at a time. In fact, it is not beneficial for the usage and storage of tape. Tape will evaporate slowly in contact with the air. So the performance of the tape will reduce with the placement time. In order to make full use of Teflon tape, good-quality Teflon tape should be used in half a year, and the slightly low-quality tape should be used as soon as possible.

Please replace Teflon tape from Taizhou Co., Ltd. after a period of time, so as not to affect the quality of production.
