Experiment § The birth of neutral dealcoholized silica gel-FX115
Four years ago, the FS series of moisture-curable resins (MS: Modified Silicone) began to be developed, and they have emerged in the market. Then we proceeded to the development of Silicone. Our idea is very simple. Now that we have developed MS products, we can also use silica gel as a sealant and we will soon produce acid and oxime FX series silicone products. These two types of products are very simple, but customers do not like their odor and hope that we can make products with low odor and neutral dealcoholization. A seemingly simple topic, but let us fall into the abyss. R&D personnel who are familiar with acid or oxime systems know that dealcoholization products are unstable because they slow down with time, their viscosity becomes thinner with time, or there are problems with storage stability. Further research found that the key to dealcoholization products is the balance between SiOH and SiOCH3. As long as it is balanced, the storage of the product is stable. But when it needs to be cured, how to break the balance and let the bridge be completed is another key. Finally, the system is stable, but the glue cannot be cured. This may also be due to the unstable system, which caused the entire hose to harden. Between the two is the relationship between time and temperature. After three years of hard thinking, it suddenly became clear one day. The neutral dealcoholized silicone FX115 series was born in the spring of 2016. I will always remember the tears of the past three years and this memorable moment, and I will not forget my original intention for research and development.

Activity § FILMTECH High-Performance Film Exhibition in Japan
Removal Tape is the latest product developed by Everwide Chemical, which is mainly used in the heavy industry market for touch panels. We expect to exhibit this product at FILMTECH High-Performance Film Exhibition in Japan in April this year. To this end, we specially invited professional video experts to shoot a video with removable tape with Japanese subtitles and an introduction. Removal Tape video:https://youtu.be/xWbeKDiUpowIn addition, at the same time, we also appeared at the Taipei Auto Electronics Show. This year we want to make some different attempts to not emphasize exhibits and promotional materials, and focus on the discussion of technical issues, hoping to make everyone have a better harvest. We are all ready and sincerely welcome you to our booth to communicate with us. The relevant information of these two exhibitions is as follows: FILMTECH High-Performance Film Exhibition in Japan,/04/06~08 2016:http://www.ftj.jp/en/Concurrent-Shows/04/06~09 2016：https://www.taipeiampa.com.tw/zh_TW/index.html
Knowledge § What is a semi-crystalline polymer?
Semi-Crystalline polymers generally look like non-crystalline polymers without crystallization, so they are often classified as non-crystalline polymers. However, this type of polymer has conditions for crystallization, but the speed of crystallization is slow, so most of the time it seems that there is no crystallization. If this type of polymer is placed at an appropriate temperature to allow the molecular chain to move easily, it will slowly crystallize, or if this type of polymer is dissolved in a solvent and the solvent is volatilized, these polymers will also Crystallization occurs. This type of polymer is most typical of polycarbonate. After placing it at 190°C for a day or dissolving it in dichloromethane and then volatilizing the solvent, it can be found that the plastic is completely whitened. Its crystals are observed under a polarizing microscope and the heat of fusion was detected in the scanner.
Living § Wangxiang Tribe
The first time I went to stay in the Wangxiang tribe was to climb Junda Mountain the next day. As soon as we enter the tribe, we can see the fields where organic corn is grown, the pheasants walking slowly in the fields, and the vineyards can't smell any pesticides. The aborigines of the Bunun tribe follow the natural farming method and cherish the grace of God. The owner of the hotel is the president of the tribe. He told us that there is no door lock in the room because the people here are content and will not be greedy for other people's things, so we can walk around in peace. After a short rest, we began to roam in the beauty of cherry blossoms and maple leaves. The small stall on the side of the road where no one is watching is full of agricultural products, and the sign says "Please put your money in the tube after you choose." I bought sweet potatoes, passion fruit, and ginger. After coin insertion, you can hear the sound of money falling into the bucket below, which is very interesting. Dinner is an aboriginal meal. Put a few tables and chairs on the grass, the owner and their little black dog entertained us warmly. The most special thing in the hearty dishes is the bamboo rice that I broke the bamboo tube with a mallet. As a delicious flavor meal, please be sure to personally experience it! It is also very important that this is a great platform to overlook the main peak and north peak of Yushan Mountain. Friends who have not climbed Yushan can come here to see it with their own eyes. When I visited this tribe with my family for the second time, I experienced the beauty of this tribe again. The next morning, the family members shouted to Yushan on the high platform, "It's cool!" This situation is truly unforgettable forever. Everyone can come here to enjoy the beauty of Yushan, appreciate the tribe, and make friends.
