� 알칼리성인 제2콜로이드 실리카와 각각 반응하여 내산성과 내알칼리성에 모두 강한 성질을 가지게 된다.That is, the water-soluble epoxy resin reacts with the first colloidal silica which is acidic and the second colloidal silica which is alkaline, respectively, as shown in the following reaction formula, so that it has both properties of acid resistance and alkali resistance.
한편, 코팅단계(S40)는 정보표시층(30)의 표면으로 유리와 규사 알갱이를 살포한 이후에 코팅액을 분사하여 보호층(40)을 형성하거나, 보호층(40)을 형성한 이후에 유리와 규사 알갱이를 살포한다. 유리 알갱이는 빛의 반사량을 증가시켜 주고, 규사 알갱이는 표면의 마찰을 증가시켜 준다. 따라서 시인성이 향상되면서 미끄러짐에 의한 각종 안전사고를 방지해 준다. 이러한 유리와 규사 알갱이는 살포 순서에 따라 도 3a처럼 정보표시층(30)과 보호층(40)에 모두 형성할 수가 있고, 도 3b처럼 보호층(40)에 형성할 수가 있다. 전자와 후자는 모두 정보표시층(30)과 보호층(40)이 경화하기 이전에 살포해야 유리와 규사 알갱이가 각 층에 포함할 수가 있다.In the coating step S40, the protective layer 40 is formed by spraying a coating liquid after spraying glass and silica particles onto the surface of the information display layer 30, or after the protective layer 40 is formed, And silica sand. Glass grains increase the reflection of light, and silica grains increase surface friction. Therefore, it improves visibility and prevents various safety accidents caused by slipping. The glass and silica particles may be formed on the information display layer 30 and the protective layer 40 as shown in FIG. 3A according to the spraying order, and may be formed on the protective layer 40 as shown in FIG. 3B. Both the former and latter need to be sprayed before the information display layer 30 and the protective layer 40 are cured, so that glass and silica particles can be contained in each layer.
이 밖에도 도 3c처럼 정보표시층(30)의 표면으로 유리 알갱이만을 살포한 이후에 코팅액을 분사하여 보호층(40)을 형성한 다음, 보호층(40)의 표면으로 규사 알갱이만을 살포할 수도 있다. 이 경우 유리와 규사 알갱이가 각 층마다 분리됨에 따라 강도를 향상할 수가 있다.3C, the protective layer 40 may be formed by spraying only the glass particles onto the surface of the information display layer 30, spraying the coating liquid, and spraying silica particles only onto the surface of the protective layer 40. In this case, the strength can be improved by separating the glass and silica sand particles from each other.
완성된 석재판(100)은 도 4처럼 사람이 다니는 인도에 바닥재로 사용되면서, 각종정보를 전달하는 안내판이나 이정표 역할을 수행할 수가 있다. 따라서 지주기둥과 같은 보조 시설물을 불필요 하므로 주위 환경을 저해하지 않으면서도 설치에 필요한 비용이 감축할 수가 있고 특히, 태풍과 같은 기후의 영향에 의해 파손되거나 낙하 따위로 인한 각종 사고를 예방할 수가 있다.As shown in FIG. 4, the finished stone plate 100 can be used as a flooring material for a person's car, and can serve as a signboard or a milestone for conveying various information. Therefore, it does not need auxiliary facilities such as columns, so it is possible to reduce the installation cost without hindering the surrounding environment. Especially, it is possible to prevent various accidents caused by damage or falling due to the influence of climate such as typhoon.
My name is Kathy Cormier-and I have filed a complaint with you about 1994-against the workout studio. Not only did you not follow your own procedures-You were the first agency I complained too, and you covered up for something that has grown way out of proportion. Your cover-up for this business has started a chain reaction.
Your procedures claim that an unsatisfied customer can file a complaint against a company. YOUR INSTRUCTIONS claim that the business owner must reply or they will not have a good reputation. Not only did Billy Lee not reply-you did not even tell me he refused to respond. My complaint was totally ignored. I found out when I called to check on the reputation of the Workout studio, and the recording said this business has no complaints. I filed a complaint, the owner did not respond- you did not tell me. When I called to talk to the director-he said he could not just put any complaint in there.
At first Workout Studio owner, Billy Lee, said I could use the aerobics room to practice dance in, then suddenly he changed his mind-even hanging up on me when I called him. Then I confronted him, and he said it was cause of insurance. Since someone who is not even a member can walk into the club and sue for tripping over a dumbbell on the floor-that was not legitimate.
World Gym opened up, and I made arrangements with the owner-that I could use the aerobics room to practice dance in. THIS IS WHERE I FOUND OUT IT WAS THE AEROBIC INSTRUCTORS CAUSING THE PROBLEMS-and they were the last ones I ever expected. This problem followed me from one fitness center to the other one.
One day the receptionist told me that the aerobic instructors said I could not use the room cause I was going to get hurt and sue-then I realize where this ridiculous excuse came from-NOW I REALLY HAVE REASON TO SUE. The owner said I could use it just as in our original agreement. NEXT EXCUSE- the aerobic instructors said the buttons were getting messed up on the stereo. Didn't work-I was still allowed to use it. NEXT EXCUSE Alyce said I was interrupting her classes-but the computer said I was in there at 7:00 am and left at 8:00 am. The class started at 9:00am. Then the owner Jody Nolan said
