In recent years, haze has continuously eroded our living environment. It has been called a healthy "invisible killer." Many people have talked about the changes and tried to reduce the damage caused by haze. The most common protective measure is masks. Someone even went abroad to buy a reassuring mask. The safety of flood prevention masks is a hot spot for all Chinese people. Then, how does a good mask with quality come into being? What kinds of masks can really make our people feel comfortable? “From material selection to R&D, we must always adhere to the quality of our products and innovate continuously to produce only First-class masks for health and environmental protection, said Wang Weifeng, chairman of Zhangjiagang Hongjing Environmental Protection Special Materials Co., Ltd. Recently, the reporter interviewed the craftsman of the mask manufacturing industry. Speaking of the original intention of starting such a company, Wang Dong told reporters that there is still a story behind this.

Due to his busy year-round work, Wang Weifeng neglects his family members, especially the growth of absent daughters is the most guilty thing in his heart. The city where her daughter was going to school was very hazy. In a conversation with her daughter, Wang Weifeng realized the harm of haze to people's health and also saw opportunities in the environmental protection material industry. He decided to rely on his own strength to produce the most environmentally friendly Healthy flood control mask.

From domestic to imported, Wang Weifeng bought masks of all models that can be found on the market and cut them out for analysis. In his view, this thing is like a battlefield. Only by knowing oneself and knowing one another can it be victorious. Every mask purchased is worthy of careful study as a sample.

In the analysis and comparison, Wang Weifeng discovered that all masks are practically a kind of meltblown technology in the market. Contaminants undergo layer-by-layer filtration, which is more efficient, and its melt-blowing is relatively thick; at a lower efficiency, its melt-blowing is relatively thin. The advantage of a relatively thin meltblown is that it has better air permeability. However, once the melt-blowing is thickened, the air permeability will be affected.

In order to solve this thorny issue, the company's team constantly develops new products, but none of them has reached the ideal state of Wang Weifeng. The shortage of funds, the frustration of R&D, and a series of problems before him. Just in desperation, an unexpected harvest made Wang Weifeng once again see hope. A nano-coated mattress at the Shenzhen exhibition opened a new direction for him. While Wang Weifeng was pleased with this new discovery, the problems followed. First, nothing is known about the waterproof formula of the mattress; secondly, the actual application and safety levels of the mattress and the mask are completely different. With no reference to the previous example, Wang Weifeng can only find the key to opening the door through all possible channels and inquiries from friends in the professional field. After several attempts, the pore size of nano-coatings needed for masks has been getting smaller and smaller, eventually reaching 0.7 micron, which is similar to the size under the melt-blowing technique. However, in Wang Weifeng's heart, such achievements are far from reaching his ideal state. If you want to do better than others, you must have the advantage of getting it. With this belief in excellence, this technical problem has finally been broken. Whether to enter the market or not, Wang Weifeng also has its own scale. As long as it is not the perfect state, it will absolutely not allow it to be marketed as a commodity. To this end, he also took the new R&D product to the most authoritative testing center in Beijing for testing.

The success of research and development, the appearance of healthy environmental protection masks is the most proud thing for Wang Weifeng. As a father, he also made a responsible account of his daughter's health. It is this responsibility that Wang Weifeng keeps strict on product quality and persistently pursues innovation in the environmental protection material industry. It is only a healthy mask and only a clean breathing environment. And such a sense of responsibility and ingenuity is our concern.
