Shanghai Wuzhifeng Information Technology Co., Ltd. is a joint-stock high-tech enterprise integrating product R&D and design, marketing and technical services. The company developed and produced the low-light quantum environmentally friendly teaching board that won the national patent technology. It overturned and eliminated the traditional blackboard and white-green board, and changed the history of writing with chalk in the past few decades. It adopts a dust-free, non-toxic, odorless and can Recycle water-based pens that are refilled with ink. Because the beige teaching board is used with a lower reflectivity than the green board, the prevention of myopia has also been greatly improved. At the same time, the projector can be projected directly onto the teaching board, so a screen is not needed. Finally, teachers can also hold a teaching pen and teach multimedia courseware directly on the board, replacing the electronic whiteboard. To sum up, the environmentally friendly teaching board is equivalent to integrating the three functions of a green board, a screen and an electronic whiteboard, allowing the classroom to enter a clean and healthy new teaching environment with environmentally friendly and low-carbon technology, and truly enter a new era of dust-free teaching. Product Features: Non-toxic and healthy. It subverts and eliminates the traditional blackboard and white-green board, and changes the history of writing with chalk in the past few decades. In the past, teachers often had to write and draw on the blackboard to explain in 45 to 50 minutes. During a class, I have to erase and write several times. When class is over, there is often a layer of white chalk dust left on my hands, sleeves, and even hair and shoulders. Do this every day, year after year, after 20 to 30 years of work, tens of thousands of chalks have been consumed, and some chalk dust will inevitably be inhaled from the nostrils. Inhaling chalk dust can gradually cause chronic and acute pneumonia, lung cancer, pneumoconiosis, bronchitis, etc. It is a matter of great concern to teachers. The emergence of environmentally friendly teaching boards has ensured the physical and mental health of teachers and students.
Environmental protection and low carbon use water-based pens that are dust-free, non-toxic, odorless and can be recycled and refilled with ink, which not only saves costs, but also solves the dilemma of ordinary whiteboards being unable to be widely promoted and applied. Ordinary whiteboards use oil-based pens, so they tend to leave stains over time and cannot be wiped clean. Also, because they are composed of alcohol, they have a certain degree of toxicity. In addition, they are single-use products and the cost is high. Water-based pens are a great solution to this problem that has plagued me for many years.
Protection of vision: Because the beige teaching board is used with a lower reflectivity than the green board, the prevention of myopia has also been greatly improved. It uses a metal substrate. The surface tone is mainly mid-low frequency yellow spectrum. The overall surface tone is mainly mid-low frequency yellow spectrum. The overall panel color spectrum is between 500---800 nanometers, and the wavelength does not exceed 8%. , is the best combination of chroma and brightness for human eyes to distinguish objects. It has soft tones, less reverse brightness, and high brightness. It can create a bright visual effect, which can relieve fatigue, protect eyesight, prevent myopia, refresh the eyes, and improve The purpose of learning efficiency.
The multimedia projector can be projected directly onto the teaching board, so a screen is not needed. Finally, teachers can also hold a teaching pen and teach multimedia courseware directly on the board, replacing the electronic whiteboard. The multimedia teaching system uses a USB cable to connect to the computer host. The software is easy to install and has no special requirements for the use environment; the teaching pen adopts an omnidirectional pressure design and a hard pen tip, which can write smoothly at any angle and supports multiple operating methods. It is simple Convenient and easy to use.
To sum up, the environmentally friendly teaching board is equivalent to integrating the three functions of a green board, a screen and an electronic whiteboard, allowing the classroom to enter a clean and healthy new teaching environment with environmentally friendly and low-carbon technology, and truly enter a dust-free environment. A new era of teaching.
