Experimental report § Anti-fog goggles and anti-fog mask
Everwide has been developing anti-fog film for many years and is committed to developing the application of anti-fog adhesive. In the actual product test, the test piece was covered on a beaker of hot water at 80°C, and the surface was free of fog for ten to fifteen minutes; the alcohol resistance test of simulating a user wiped with alcohol, the abrasion tester load 200g, After dripping alcohol on the sheet and wiping it with a dust-free cloth hundreds of times, it still has an excellent anti-fogging effect (Figure 1-3). The advantages of this type of adhesive used in masks (Figure 4) and goggles (Figure 5): 1. Good anti-fogging performance; 2. Good alcohol resistance, can be reused after alcohol disinfection; 3. High transparency It can prevent liquid splashing; 4. It adopts all UV solvent-free environmental protection process, and has sterilization effect after being irradiated by ultraviolet machine; 5. The product has passed CE, FDA, SGS, EN166, ANSI Z87.1... and other certifications. Long-lasting anti-fog goggles can pass high temperature and high humidity at 85°C/85%RH for 500 hours, low temperature resistance at -40°C for more than 250 hours, and wear resistance for more than 5000 times.

Recently, Everwide held a photography competition. The content of the event focused on the company and recorded the beautiful moments through the lens. The purpose of this activity is to promote mutual connection and interaction through soft activities outside of work and increase understanding of the company. After fierce competition, the factory voted for the three most popular excellent works (Figure 1-3). Finally, I would like to thank my partners for participating, as well as creative submissions, winners and coordinators (Figure 4).
Knowledge exchange § Can surface treatment definitely improve the bonding strength?
The adhesive is used to remove the adherend. After the test piece is damaged, it can be roughly divided into two situations. One is that the adhesive and the adherend are separated, and there is no adhesive residue on the surface of the adherend. This situation is called Adhesive failure); Another situation is that the adhesive breaks by itself, and there is adhesive residue on the surface of the adherend. This situation is called Cohesive failure. When it fails, surface treatment should be performed on the bonded object to increase the bond between the two to increase the bonding strength.
Biweekly strike § Return to nature
Not long after I joined the company, I was lucky enough to have a great opportunity to climb the North Peak of Hehuan. My mind awakened in an instant. I was touched by nature after a long absence, so I decided to join this mountain trip. On the day of departure, everyone gathered at the company early in the morning and set off happily on the minibus. The wind was bright and beautiful along the way, and the atmosphere on the car was full of joy. About three hours later, we arrived at the mountain pass of Hehuan North Peak. Being in a high mountain with thin air, feeling the surrounding mountains and forests, the mood gradually became agitated, and after finishing the equipment, he was ready to go and ready to attack the top. At the beginning, it was a stair trail, so it was relatively easy, but when it reached about one-third of the trail, rocks of different sizes appeared, and you had to step on it carefully to climb up. Slowly I felt the energy in my body, which was consumed violently due to the low temperature and strenuous climbing. Fortunately, the beautiful scenery along the way gave me the strength to continue climbing. At this time, the surrounding clouds became thicker, and the vast sea of fog accompanied by the wind blowing on my face made me a little nervous, but in the end, with unremitting efforts, we finally reached the top of the peak. It was a moment of excitement. The road of life is like climbing a mountain. In the process, there are rugged roads and steep peaks. Although people are exhausted physically and mentally, they still look forward to seeing the beautiful and infinite scenery after crossing the mountains. Only by bravely stepping out of the comfort zone and insisting on never giving up can you get a glimpse of nature and try to explore a better version of yourself.
