Nice to meet you. I am Fuji Sava III, chairman of Fujisawa Sei. Fuji Shawar is a construction company that ushered in the 98th anniversary of its start-up in 2021 and carried out time-honored brand "construction, equipment maintenance". Fixing the "failure" of buildings and equipment is not only to restore the original state, but also to help you "do better". To put it bluntly, this is the "professional engineering industry of painting and waterproofing engineering". In order to make it clear that it is a professional company of building maintenance, it dares to "construction and equipment maintenance industry".

　So, Fuji launched the contact infection response package "virus headlines" in July 2020, in this story, starting from the encounter with the photocatalyst used in the virus headlines, summing up the repeated experiments and intentions so far.

　With regard to the contact with the infection countermeasure package "virus top", the two people in the new career promotion department have summed up different stories, please be sure to confirm.

Encounter with photocatalyst

　Do you know "photocatalyst"? With the expansion of novel coronavirus's infection last year, the popularity as an anti-bacterial and anti-virus strategy continues to increase, many people have heard of it. I remember that the encounter between Fujisawa and photocatalyst was the "Building Materials Exhibition" in March 2013. It was eight years ago. In April 2012, Fujisawa made his last job-hopping in his hometown Fujisawa as an executive director, and attended various exhibitions in order to collect information. Although it is a time-honored professional engineering industry, is there anything else to do besides painting? I thought about a lot of things after I joined the company. I also have a lot of ideas now.

　Since the early days of Pingcheng, both "public works" and "private enterprise contracted projects" have become the pillars of the cause, but they have been included in the framework of "painting waterproofing works", which is a pity for Fujisawa. If you change the exterior decoration, you should take "one-stop" and "diversification" as the goal by means of decoration and renovation around the water. In other words, considering the 100th anniversary paragraph and the position of the third generation, it is necessary to change the career content from "painting waterproofing engineering" to the broader "building equipment maintenance industry". At this time, in the building, building materials exhibition is encountered is the "photocatalyst."

Be attracted by the possibility of photocatalyst

　At that time, photocatalysts were introduced outdoors through "self-cleaning" to prevent dirt, and indoors through "oxidative decomposition" of deodorization, antibacterial and antivirus as functions and effects, which are basically unchanged now. Fujisawa took a strong interest in this explanation, arguing that it seemed to work in synergy with existing businesses. The photocatalyst itself has heard the name to some extent, but painting the same spray gun construction and so on, it is very attractive to deal with it without a sense of disharmony in our company. Most importantly, the "feel of everything" of photocatalysts, as "building equipment maintenance", is an important part of further improving the content of diversification proposals. Dirt and mold adhesion on the exterior wall is an eternal theme that is difficult to prevent with paint alone, so if the coating cannot be suppressed, photocatalyst can be chosen. In addition, since it is expected that indoor antibacterial, antiviral and deodorizing functions will be important needs in the future (unfortunately, this has been the case by 2021), it can be said that there is no other substitute for colorless, transparent, odorless photocatalysts that can give antibacterial and antiviral functions.

　Therefore, Fujisawa, who decided to deal with the photocatalyst in our company, first decided to recommend the photocatalyst to his acquaintances. Although it is now quite well-known, but eight years ago, almost all people do not know the photocatalyst itself, Fujisawa himself was only heard of the state, how to do business well, everything is a state of groping. Among them, the hall of the composite facility in Qianqiao City got the news that he was worried about the smell of cigarettes, and put forward a test construction plan on the ceiling of the hall wall. Fortunately, the test construction was forgiven, and the actual construction on the walls and ceilings of the hall, even now, can not be fully thanked by that person. Then, after the actual construction, the photocatalytic coating is indeed colorless and transparent, if we do not look at the construction situation, we do not know whether there is really a coating, but will produce a sense of insecurity, which is a good memory (laughter).

"visualization" photocatalytic effect

　Because what is needed is the deodorization of the smoke, the photocatalyst coating must be used to reduce the smell in the hall, where he suddenly said, "how can I prove that the smell can be reduced?" "I realized. Moreover, other photocatalytic effects such as "reduction of VOC in the air" and "surface antibacterial and antiviral" can not be simply quantified. These are completely unprofessional. Without the help of others, the occasional photocatalyst coating will be said, "I have tried, but I don't know if it has any effect." not only can not sell it, but it has joined the ranks of "fraudulent services" and created a sense of crisis.

　In this sense, in the implementation of the initial test construction of photocatalytic coating, Fujisawa will devote himself to the next major topic-"quantification of photocatalytic effect". In various surveys, I came across a new book called the Home for Asthma and atopic cures. One of the books includes Fujisawa's current mentor (later doctoral program), Associate Professor Huizang Mantiamura (Qianqiao University of Engineering), which studies indoor air quality and warm environment from the point of view of building environmental engineering. Fujisawa learned that there were experts in Qianqiao city and immediately contacted Qianqiao Engineering University to apply for joint research. Once the goal is set, there will only be action. The joint research with Mr. Mitiamura immediately decided that the license for the composite facility in Qianqiao City was also obtained, and the measurement of "air quality improvement effect of photocatalyst coating" began. The joint study was finally carried out at the compound facility in Qianqiao City for two years, and the results were summarized by Fujisawa as a paper. Known as "academic marketing", plasma cluster ions (Sharp Co., Ltd.) and Blu-ray Lens (Jinz, Co., Ltd.) are well known, and Fujisawa also takes into account these for data analysis and business activities. The problem of how to transfer the intangible effects and services of photocatalytic coating to customers is the same as plasma cluster ions.

Repeated experiments led to the development of "virus top".

After that, in the process of facing various customer issues, in the cases that are difficult to solve without photocatalyst, we actively put forward the photocatalyst and accumulated proprietary technology and success stories. The roof and outer wall are coated with photocatalytic coating, although it has been successful in general cases, but there are also failures as a mold countermeasure, and it has become a good opportunity to investigate why it failed. For indoor antibacterial and antiviral, because there is almost no demand, so there are few proposals, after 5 years (wry smile). However, a series of activities that have continued since 2013 are closely related to the "virus first". As a result of the joint study, although "the photocatalyst coating on the wall ceiling does not improve indoor air quality", it has been proved that "the surface of the photocatalyst coating remains beautiful for a long time". The top of the virus defined its status as an "effortless contact infection strategy" from the very beginning.

Take the century-old enterprise as the goal

　This is a little short of the 100th anniversary of the start-up, which is why we think it is necessary to update the business structure through "creating new business" and "diversification". In this case, what you realize is "don't give up". In the case of limited human and financial resources, it is OK to take the time, take the time to realize, and in short, aim to gain unique know-how.

　The cause that can last for more than 100 years is due to the "accumulation of challenges" of the predecessors who have always supported Fujitsu. In the future, Fuji Shawar will not give up various challenges, continue to accumulate, make greater contributions to social issues of enterprises, tasks "to bring happiness to all." Continue to move in the direction of realization.
