Interactive platform § The sweet power of one square centimeter
When planning the electronic exhibition, I thought about how to show the "pull force", how to show "the substrate with a small adhesion area, but it can show a great pull force". We often do customer service by gluing carbon fiber to aluminum sheets so that customers can send them for pull tests. However, it was a bit of a fuss to deliberately move the tensile machine to the venue to show the audience the tensile force of a steel cable with a length of only ten centimeters. But it was a coincidence that when I turned on the TV one day, I happened to see "Pigs die and look beautiful" - that's Discovery! The content of the program is that under the same diameter, the pulling force of a bundle of iron wires is several times that of a wire. So, two carbon fibers adhered to aluminum sheets, plus two thin steel cables, and then tied to the wooden board, the last basic appearance of the swing came out. In fact, this is not enough, the swing should not only be able to sit, but also be safe! The steel cable of the swing looks very thin, but it is actually very safe. The tensile force of the unilateral steel cable exceeds 120kg, and the bilateral tensile force can reach more than 240kg. During the electronic exhibition, many people paid attention to the swing and wanted to sit on it, but the steel cable was too thin, which was really scary, so they had to sit on their own and show them to the visitors. When everyone saw that we dared to sit, they felt more at ease, and they also tried to sit on it, shake it around. There was also a small episode during the exhibition. On the first day of the exhibition, a gentleman from India saw the swing and was very interested. He hoped that we could send the swing to him after the exhibition. He came back early the next morning to remind us again. On the afternoon of the third day, he came again and said that he was about to go back to India, and I hope we don't forget to send him the swing. This year's swing successfully showed the company's characteristics - "Although it is thin, it can have great power!"

Experiment § Foaming
Foaming technology is a fairly mature technology, and NC198 is different from the previous foaming materials in that not only the viscosity, hardness, and foaming ratio can be adjusted according to the different requirements of customers, but more importantly, it is maintained regardless of the hardness. It has high toughness and will not break when struck at low temperature (-20oC). NC198 can be foamed and cured at 150°C / 10 minutes. It is a single-component foamed rubber, which can avoid the problem of uneven mixing and mixing. This foam material is mainly used as a filler material for composite materials. If you want to form irregular-shaped composite materials, you cannot use ordinary iron molds that can be wrapped or wrapped. However, through the use of foam material, the composite material can maintain its shape and closely adhere to the outer mold before it is cured. Because of the low density, the weight burden caused is not obvious. This styrofoam can also be foamed separately. If there are restrictions on lightweight and weight, or if you want to reduce the weight of the filling material but still maintain the original rigid material, you can try this styrofoam.

Knowledge § Dispersible and melting type one-component epoxy hardeners?
There are two types of single-component epoxy resin curing agents: dispersion type and melt type. How to distinguish?
The curing agent is made into a powder that is insoluble in the resin at room temperature, and dissolves into the resin at high temperature, and is dispersed into the resin by mechanical equipment. Since the curing agent is not actually dissolved in the resin at this time, this curing agent is classified as a dispersion type.
Some curing agents can be completely dissolved in the resin to form a homogeneous and stable system. These curing agents have special temperature sensitivity, and dissociation occurs only when the temperature is above a certain temperature, allowing the resin to undergo a curing reaction. Since these curing agents can actually dissolve in the resin, this curing agent is classified as a melting type.
Living § 2009 International Electronics Show
From October 8th to 11th, it is the best time for the electronics industry to advertise itself. Of course, Everwide Chemical should also sign up. As early as three months before the competition, everyone racked their brains, thinking, what kind of performance will attract the attention of passers-by? So the sand table deduces everything that may happen. Adhering to the concept of innovating the old and bringing forth the new, this year's exhibiting products have gathered the skills of Everwide for nine years, which is very surprising! Seemingly slender but with a tolerance beyond ordinary people's swing, it attracted a lot of attention. In addition, the process of making carbon fiber composite materials in detail makes foreigners and people in jewelry-related industries more interested. Not to be outdone, the encapsulation glue of LEDs and electronic ICs is not to be outdone. Although the sparrow is small, it has all the internal organs, so there are many people asking. Although the thermally conductive plate needs to be "cooled" quickly, it cannot be left in the corner of the cabinet at this time. It is comparable to the thermally conductive plate of the silicon thermal conductive sheet and the aluminum substrate of the same industry. Acrylic boxes filled with various packaging materials form a wall to resist foreign enemies and consolidate internal confidence, which also shows our strong strength and quality assurance. The ancients said, "The eyes are the windows to the soul". Everwide's eyes are large 32-inch LCD screens, which will attract passers-by and make them stand for more than 5 minutes. The guppy with a big belly was performing hard, and also played a special part in giving birth to small fish. Of course, the glass glue is also more important at this time. In order to prevent the 5 kg stone from pressing on the small fish, the glass glue had to work hard to lift such a heavy stone. Brilliant colors are always the most attractive, and the reflected light of the brightness enhancement film and the figure-8 LED lights are projected into the eyes of passers-by. In addition, there are IMD, IMR, and glass ornaments with beautiful patterns, which surprise people even more, as if life is in vain without seeing this treasure. The current trend is ultra-thin mobile phone buttons, but it is also facing difficulties. This beat other very good keys let the traditional keys feel inferior. However, the technology of nameplate perfusion and flat cable reinforcement has made a name in the traditional industry, as well as the guarantee of UL94V-0. Having said so much, the exhibition products of Everwide Chemical this year are varied and dazzling. If you missed this wonderful exhibition, you are welcome to come and guide in person next time.
