Experiment § New instrument: DiscovIR-LC
Recently we introduced Taiwan's first "DiscovIR-LC" (Figure 1). This instrument uses a new generation of infrared spectroscopy analysis technology, combining gel permeation chromatography (GPC) and Fourier-transform infrared spectroscopy (FTIR). The diluted mixture solution is first chromatographically separated using a GPC column, and then used with "Spectra Analysis" company's exclusive patented concentration technology "Hyphen" to remove most of the solvent. Finally, the separated products are sequentially deposited on the continuously rotating zinc selenide disk (Figure 2), and the various components in the mixture are analyzed by scanning the infrared spectrum at different points (Figure 3). Since this instrument is a continuous online analysis, when the sample is too small, the sample can be repeatedly injected to increase the thickness of the deposition and enhance the signal intensity of the infrared spectrum. "DiscovIR-LC" can not only be a tool for our analysis, but may also be helpful in the identification of contaminants. We are still accumulating experience in operating this instrument, and we often have unexpected gains. If you have any related needs, you are welcome to contact us. -Author: Dr. Jia-Ling, Liao
Activity § Work-life balance in 2024
In 2024, we held about 23 employee events. Static activities include plant rubbings, cooking, weaving dream catchers, making massage oil, etc. to help them relax and relieve stress. Dynamic activities include trail exploration, challenging Hehuan East Peak, yoga, Tai Chi, self-defense and weekly badminton activities, etc., allowing everyone to develop exercise habits and maintain a healthy body. Charity activities include beach cleaning, watching charity baseball, and booking theaters to support Taiwanese movies, aiming to raise everyone's attention to society and the environment. Cultural exploration activities include touring Xiluo, visiting different industrial factories, and gaining an in-depth understanding of Taiwan’s history and culture. Through these diversified activities, we hope that everyone can have a fulfilling and meaningful life besides busy work. After several years of hard work, the participation has continued to increase, which is the happiest thing.
Knowledge § What is Reactive Type Inorganic Adhesive? (4)
Water has another very important function: controlling the rate of cure. Since the reactive type can usually start the curing reaction at room temperature, if the amount of water is too little, the storage time in refrigeration (5℃) is often less than a week; inorganic adhesives will clump when frozen and cannot recover when the temperature returns, so they are not suitable Store frozen. Adding additional water at this time can effectively reduce the curing rate, and the refrigerated storage time can be greatly extended to several months. The principle is that water will shorten the distance between the reactants, and its curing rate is often lower than that of water with a lower reactant concentration but a lower proportion. The recipe is even slower. However, the viscosity drops significantly after adding water, which also affects the adhesion force, mechanical properties and thermal expansion coefficient. Therefore, the types and proportions of other contents must also be adjusted.
Living § Exhibition experience
This is my first time to attend the Taipei International Automotive Electronics Exhibition. Before the event started, my partners told me not to be too nervous because the team would support each other, which made me feel relax. After the exhibition officially started, my colleagues took me to visit the booths of various dealers, and listened to their introduction to automobile manufacturers about the application of Varnish and PU infusion. I also received feedback from dealers on KA series products: some products are not suitable for those with thicker thickness. The effect is excellent on thin workpieces, but less effective on thicker workpieces. Whether good or bad, these opinions have value for the development.
When I returned to the company booth, I quickly encountered a challenge: a manufacturer asked about aerogel products. Because I had no exposure to relevant information, I couldn't deal with it immediately. Fortunately, the senior colleagues help me to answer the question immediately. Seeing everyone's strength makes me admire them and reminds me that I need to keep learning. After the event, I set off on my way home. When High Speed Rail arrived at the destination, I saw my son holding a sign and heard him shout "Mom, I love you." Suddenly, the fatigue disappeared. I gained a lot from this exhibition experience. No wonder my senior said before departure: "Participating in an exhibition can help us grow a lot." It is Real! -Author: Mrs. Xiao-Yi, Xie
