Experiment § Abrasion testing machine

Recently, Everwide Chemical has added a lot of new functions to the equipment; this article will introduce the abrasion testing machine for readers. Abrasion testers, pencil hardness testers, and other abrasion machines are all methods used to evaluate coating characteristics.

The difference between the abrasion test and the pencil hardness: the abrasion test is the continuous damage of the surface by the previous covering action, and the scratch resistance of the surface is observed, which is a long-term evaluation; the pencil hardness is a direct evaluation of the relative hardness of the film surface and has no time problem. In the past, when customers asked us to evaluate wear resistance, we used self-made hand tools to simulate (Figure 1 shows steel wool, and the yellow arrow represents repeated friction actions). Although this test method has also helped us complete many customer cases, it will also distort due to human error (the speed and the weight of the pressure are inconsistent each time). On the other hand, the weight of the pressure continues to increase with customers' needs, and such complex tests as repeated rubbing with hands can no longer meet the requirements. We purchase abrasion testing machines, which can be closer to the client's application and assist in developing higher specification products. At present, we can carry out an abrasion test with a load of up to 1kg on both sides and can set the speed of the reciprocating motion (the fastest 60rpm) and the maximum number of tests of 6 digits (Figure 2, 3). If you have any needs in this regard in the future, please feel free to discuss with us.

Activity § 2014 Year-end Meeting

A former colleague once mentioned that the most impressive thing at Everwide was that all colleagues had a meeting at the end of the year. This tradition has been going on for several years. We end the work at hand, review the results of the past work together, and share the latest products developed by each group. In the meeting, everyone will vote for the best employee, and the moment the vote is issued is the climax of the event! In addition, we will also watch a movie with a different theme every year, discussing the future, life, and work. This year's "Everybody's Fine" explored family relationships, and many colleagues have deep feelings! Every year we will make exquisite manuals to record these bits and pieces.

Knowledge § How to decollide and precautions?

Customers often ask us how to decollide the hardened resin (how to remove the hardened resin)? In theory, thermoplastics can melt and flow at high temperatures and can also be dissolved in specific solvents, so there is relatively no problem with decolliding. Due to the cross-linking of thermosetting plastics, it will not melt and flow at high temperatures, nor will it dissolve in solvents, so it is not easy to remove, leading to decolliding. Then again, to remove the hardened resin, it is still nothing more than temperature and solvent. Although thermosetting plastics will not melt at high temperatures, they will soften and lose strength. Some subsequent objects can be unplugged at high temperatures for heavy work, and some parts can be peeled off at high temperatures, using the softening properties of high temperatures. Some applications cannot withstand high temperatures, and at this time, the glue can be soaked to remove the solidified substance. Most of the decolliding agents are solvents of specific polarity; although there is no way to dissolve the cured resin, the resin will swell and swell due to the absorption of the decolliding agent and break into small pieces of glue and fall to achieve the goal of decolliding. This method is sometimes time-consuming, sometimes there are concerns about industrial safety and environmental protection, and sometimes there are other plastic materials nearby that will be destroyed, so it is not completely applicable.

 

Living § "Add yourself" Oil Essence

One day in 1996, a Japanese ran to his uncle and said that he had an oil formula certified by a Japanese car manufacturer. Pour this oil on the engine to repair wear, reduce engine noise and reduce fuel consumption. Wait, the benefits are endless. At the same time, a stack of reports was presented, which included analysis of uphill, downhill, idle, urban areas, and highways. Everyone was happy, saying that this was a gift from the sky. In my impression, the formula includes boron nitride, antioxidants, and recycled salad oil.

The Japanese taught the second uncle to wind a copper wire on an iron pipe and flow the finished oil through the iron pipe when the copper wire was energized. It turns out that this function is like an electromagnet; it must absorb any iron content in the oil to avoid running into the engine. The third uncle was very opposed to this matter and read a lot: The origin of the formula is unknown, the effect cannot be confirmed, whether the manufacturing process is reasonable, and there is no address and telephone number on the jar. If there is a problem with the product, who should be responsible for the vehicle repair? At the end of the story, I went to serve in Kinmen. At the beginning of 2000, my second uncle came to visit us and took a dozen oil essences from the car. I remembered what happened back then and asked him what the end of oil essence was? The second uncle said: After exporting two batches to Japan, that person lost contact without paying. Initially, my eldest uncle wanted to consign it to the gas station for sale, and the name was also named "Add it yourself," but later, it disappeared. A while ago, I found those tins of rusty oils in the basement, and I couldn't help but laugh when I recalled my dreams but it was surprisingly found that the above Japanese written in NASA certification passed? What the hell. This story tells us: 1.Gifts will not fall from the sky; 2. Never produce something that we cannot be responsible for.
