Experiment § Silicates Inorganic Adhesive
Inorganic adhesive is mainly composed of inorganic matters, including adhesive, hardner, fillers and water. The main characteristics are heat resistance, low coefficient of thermal expansion and can bond with various materials, such as ceramics, metals, glass, stone, woods, and so on. There are 4 types of inorganic adhesive which are hydraulic, air-drying, hot melting and reactive. Silicates and phosphate are the most representative among reactive type. FH009 is silicates type inorganic adhesive. After burning at 1,200°C for 60 seconds, the appearance only slightly oxidized to light gray, but kept complete inner structure without cracked, melting, burning and smoking (Figure 1, 2). According the data of TGA (air, 10°C/min), when heating to 840°C, rate of weight loss is less than 2% (Figure 3) which offers compelling proof that reactive type can resist heat over 1,000°C. FH009 exhibits extremely low coefficient of thermal expansion. When secondly heating to 840°C, rate of weight loss is only about 7ppm/°C (Figure 4). The adhesion strength to different substrates as followed: 304 stainless steel 23 kg/cm2, 316 stainless steel 33 kg/cm2, copper 11 kg/cm2 and glass 14 kg/cm2. FH009 must heating curing in stages, its curing temperature and time is 80°C for 1 hour and 120°C for 1 hour to avoid too fast water evaporation which leads to bubbles.

Activity § Embrace Healthy Life from Quitting Smoking
Everwide has encouraged colleagues to join outdoor activities to make a balance between working and living. Also, hoping colleagues to quit the habit that will do harm to their health, such as smoking. We had advocated for quitting smoking from 2012 and had praised and awarded colleagues who quitted smoking successfully. So far to 2024, there are 6 colleagues who has successfully quitted smoking for their health. This action is not only good for health but also saves a sum of money. There is a great saying from one of the colleague who quitted smoking successfully: ‘Temporary gratification would rather than leading a healthy life.” (Figure 1~5)
Knowledge § What is Reactive Inorganic Adhesive (3)
Many curing conditions are for controlling water volatility. If temperaure becomes too high fast and water even boiliing will make adhesive have a lot of bubbles, inflate and disorganize structure, increase coefficient of thermal expansion and lower mechanical property. If temperaure becomes too low even room temperaure, water volatility is too low will make curing time longer and lower crosslinking density will increase coefficient of thermal expansion and lower mechanical property. Heating in stages will minimize bubble amount and make compact structure and increase mechanical property, lower coefficient of thermal expansion meanwhile. To reactive inorganic adhesive, curing conditions are as important as formula. Even same formula will make totally different results with different curing conditions.
Living § Everwide in My Eyes
I have learned a lot in during two-month internship Everwide in second manufacturing department. The senior taught me hand by hand at the beginning and actively guided me to work. Let me be familiar with the procedure of the order dealing step by step. The content of internship is not difficult, but there are many tips for practicing, such as how to debubble and use centrifuge. I gained a lot from the experience of seniors. I realize about the distance between theory and practices. It is hard to avoid making mistakes in the process. Once I overthrew the container due to operating mistake, however; the senior did not scold me. She dicussed how to aviod similar mistakes. Besides of learning the skill, interacting with them made me feel Everwide like a big warm family even though the experience and age of eveyone are different, but we just treat each other like friends. We worked, chatted, even shared funny story together. In addition, the audio-visual instruction on every Friday helped me understand more about every department and the operation of Everwide, especially for the considertion of career development. In these two months, I learned several professional knowledge and experienced the human touch of workplace. It is a significant growth for me. Appreciate the internship opportunity that offered by Everwide. I will devote myself to growing. ─Author: Ms. Fang-Ting, Zhu
