New Functional Materials - Comparison of ETFE and PTFE

ETFE is a fluorine-containing polymer thermoplastic material, is a high-strength fluoropolymer, with good durability, easy cleaning, and stability. PTFE is a chemically inert material. The glass fiber as the substrate to form PTFE membrane. PTFE also has excellent durability, stability, and easy cleaning characteristic. The fire resistance of ETFE film and PTFE film can reach the B1 level, so they can be used for the flame retardant material.

Features of ETFE

1. The pre-tension strength can be applied.

2. Has resistance to temperature changes, can be directly exposed to the temperature of -200 ℃ -150 ℃.

3. The light transmittance can be as high as 95%. The translucency of the material can be further reduced to 50% by surface printing.

4. Has the characteristics of anti-high pollution and easy to clean, the rain can usually remove the main dirt.

5. ETFE is a completely recyclable material. After the separation of impurities, it can produce other ETFE products.

6. Has corrosion resistance, has a unique adhesion characteristic with the metal so that ETFE (F-40) and metal are the ideal composite material.

7. ETFE film life of at least 25 to 35 years.

Features of PTFE

1. PTFE is characterized by high strength. Medium strength PTFE film has the thickness of only 0.8mm, but its tensile strength has reached the level of steel.

2. The use of a wide temperature range of -70 ℃ ~ 230 ℃.

3. Has unique optical performance. At the daytime, incident light will become natural light, to prevent dazzling, no shadow, light evenly distributed, almost no UV transmission, to prevent the internal decoration materials and equipment from fading. At night, high reflection performance makes the room with excellent lighting effects, reducing power consumption. Has a high light transmittance of 13%.

4. Self-cleaning is good, the rain can wash away the surface attachment.

5. The service life of more than 25 years.

As the ETFE film is directly made from the plastic film, so its tensile strength is weaker than the  PTFE, and the one-time investment and maintenance costs are high, so fewer manufacturers has the ability to produce ETFE film. However, PTFE has a very wide range of applications, including all types of sports buildings, exhibition buildings, airport buildings, and facilities, etc.

If you are interested in the PTFE, I will recommend you this Teflon film sheet which is made of PTFE and not expensive at all. It can be used in many ways as it is hardness material of high strength and high/low temperature/corrosion resistant and very durable.

Electronic equipment DIY entry - tool selection

Why play electronic DIY, it is fun?

A: First, you can quickly grow various knowledge in this area. Second, electrical equipment might be out of work and you can fix them by your own as you have known the most principle, and your friends will ask you all questions about electronic equipment so that you no longer need to rely on the maintenance stores. Then there is the development of playing model aircraft, playing car models, but these we will talk about in other chapters.

On the choice of tools, we will first explain the most basic tool - the soldering iron.

Ordinary soldering iron

Common soldering iron is generally divided into two types: internal heat and external heat.

Advantages: cheap, can be found in any ordinary hardware stores.

Disadvantages: temperature control is not allowed, the temperature changing is slow, the tip of poor technique, poor thermal conductivity, easy to oxidize, or even burn the fever core, heat capacity is small, not easy to control and weld.

936 soldering iron

Advantages: you can adjust the temperature, not easy to burn the pad, a variety of soldering iron tips to choose from, use the 936 heating core, affordable.

Disadvantages: temperature changing is slow, tip heat conduction is poor, heat capacity is small, the temperature is not real-time digital display, bulky.

High-end product line

Speaking of high-end products, I have to mention the HAKKO Soldering Iron. The solder iron station is the hot core, tip, temperature sensor integrated design, so the temperature transfer effect is good.

Advantages: temperature rises rapidly, according to the solder joint to automatically adjust the output power, a variety of soldering iron tips to choose from, convenient to use.

Disadvantages: host prices and supplies are relatively expensive.

In this case, after comparing all kinds of the soldering irons, I will definitely recommend the HAKKO FX-951 which is high-quality and high-performance but not high-price. This soldering iron station with tip has all-in-one complex tip design, strong heat recovery for lead-free soldering and temperature control by card avoid random temperature change. And if you need any jumper cables color your DIY process, I will also offer you a smart choice.

Why e-cigarette is so popular now

What is e-cigarette

In fact, e-cigarette and cigarette are completely two different things. In terms of smoke, one is the fog generated by the high-temperature atomization of the liquid, and one is the solid particles produced after combustion, purely two concepts. Therefore, the e-cigarette is an equipment which use electricity to heat the smoke generated by E-liquid, then the user inhales the smoke.

Whether the electronic cigarette is harmful

To determine if the e-cigarette has harm to your health, 90% is determined by the quality of E-liquid level. As for the E-liquid, compared to normal cigarettes, the harm is relatively quite low. Therefore, according to the use of electronic cigarette materials and the composition of the E-liquid, electronic cigarettes are more healthy and safer than the burning type of cigarettes.  Whether electronic cigarettes will harm the human body, the scientific findings have not yet unified. The smoke produced by electronic cigarettes is vapor, without any harmful substances and smoke tar, so the release of smoke is not so smelly and has less harm, so it also has some advantages for the public environment.

Help to quit smoking

Electronic cigarettes lighter taste, after a period of smoking, and then smoking ordinary cigarettes will feel particularly choking. Therefore, for those who are addicted to cigarettes, electronic cigarettes can reduce the physical and psychological dependence on cigarettes, so to help quit smoking.

Benefits compared with smoking

As the e-cigarette does not need to burn, so there is no flame, and soot and cigarette butts, so there is no fire hazard. So e-cigarette is more secure and more environmentally friendly. Good quality e-cigarette tastes good, has multiple flavors to choose, and has no smell after smoking. You can keep fresh breath so that will not cause interpersonal social distress. The e-cigarette is more convenient too. An e-cigarette equivalent to a few packs of ordinary cigarettes which is easy to carry and can be used anytime anywhere you want.

Battery

Regulating rod generally use polymer batteries, and the better one can use 18650 battery and 18350 or other models of lithium batteries(I will definitely recommend the 18650 battery charger and the 18650 battery case which is also practical). Because of the circuit board restrictions, so the pressure of the release of the current flow is about 2,100 to 3.5A, and the voltage is about 3V to 5V and has a low resistance limit, usually 1 ohm below. The mechanical cigarette rod has the current power about 6A, and the mechanical smoke rod does not limit the minimum resistance, full power state voltage of 4.2V, the minimum voltage of 2.75V. So the ego automatic battery might be an excellent choice for you.
