Qingdao Nanshu Taixing Technology Co., Ltd., established in September 2005, has been dedicated to the research, development, production, and application of new carbon materials for many years, with meticulous management and continuous innovation. It currently owns 26 invention and utility model patents. In 2014, it became the first "technology enterprise" in the city's graphite industry. The company always adheres to the principle of technological innovation, the business philosophy of superior quality, and the corporate spirit of people-oriented and dedication to society.

The company has successively passed ISO9001 quality management system certification, ISO14001 environmental management system certification, and safety and environmental protection dual-system acceptance. It has also promulgated and implemented the industry's high-product standard [TS001-2018] for ultra-thin graphite heat dissipation films, registered the "Nanshu" and "Nanshu Taixing" trademarks, and gradually improved the market recognition of its products. It also participated in the formulation of the industry group standard for graphene electric heating films and won the Shandong Provincial Circular Economy Science and Technology Achievement Award in 2018.

In 2011, the company cooperated with Harbin Institute of Technology (Weihai) to successfully develop a high-thermal conductivity ultra-thin heat dissipation film. The successful development of this project filled a domestic gap, won the National Science and Technology Innovation Fund, and was included in Qingdao's emerging strategic new material support project. Currently, the company has two ultra-thin heat dissipation film production lines with an annual production capacity of 1 million square meters. The research and development of this project effectively solved the thermal management problem of electronic products and can be widely used in mobile phones, tablet computers, televisions, LEDs, and other communication equipment.

Since 2015, in response to the "coal-to-electricity" policy and people's pursuit of healthy living, the company has invested more than 3.1 million yuan in cooperation with Harbin Institute of Technology (Weihai) and Zhejiang University's School of Materials Science and Engineering to research and develop graphene electric heating films and their various application products. After three years of unremitting efforts, at the end of 2017, it successfully broke through the technology of graphene inorganic composite electric heating films and graphene PTC (self-regulating temperature) electric heating films. Graphene inorganic composite electric heating films can be widely used in various electric heaters and industrial heating appliances. The successful development of this technology effectively solved the problems of pollution in the production process and oxidation attenuation in the application process of the original metal heating films (wires). According to the infrared electric heating detection center, the electrothermal conversion rate of graphene inorganic composite electric heating films is over 98%, with zero attenuation in a usage environment of 400℃, and an infinitely long service life. Graphene PTC (self-regulating temperature) electric heating films effectively solve the high-temperature safety hazard problem of constant-power electric heating films that has plagued the industry for many years. According to the infrared detection center, the electrothermal conversion rate is 98%, with slight attenuation after 30,000 hours, a far-infrared total normal emissivity of 88%, and an infrared electrothermal conversion rate of 68%. It is widely used in residential heating, far-infrared health therapy, and heating of greenhouses for animals and plants. PTC (self-regulating temperature) technology is a technological revolution for electric heating films. Our company's PTC (self-regulating temperature) technology once again fills the gap in the industry's technology, leading domestically and reaching internationally advanced levels.

Entering 2018, the company invested more than 5 million yuan to improve production process technology and, in conjunction with relevant automation equipment manufacturers, jointly researched and put into production one automatic die-cutting production line for graphene inorganic composite electric heating films and one automatic cutting production line. This enabled the process production of graphene inorganic composite electric heating films to achieve standardized automated production, with an annual production capacity of 3 million square meters. It also researched and put into production one graphene PTC slurry production process, one automatic PTC printing production process, and a series of related supporting process equipment. Production is initially on a large scale, with an annual production capacity of 1.5 million square meters of PTC electric heating films, which can initially meet market demand. The company will continue to increase investment and expand production scale to meet the growing market demand.

With the improvement of electric heating film technology and processes, two major series of electric heating products have been continuously developed. First, residential heating products: low-temperature radiant floor heating encapsulated films suitable for different floor installations. This electric heating film effectively solves the problem of induced current. The cost of installing floor heating film is low, construction is simple, the heating speed is fast, and it can reach 18℃ after 4 hours of initial operation. It's a one-time investment with permanent benefits; integrated heating wall panels and kang panels suitable for offices and rural "coal-to-electricity" projects. Integrated wall panels have a large heat dissipation area and quick construction, solving the heating problems of already renovated and used houses. Integrated kang panels are a choice for coal-to-electricity projects in rural areas, using a safe and reliable 24V DC power supply, providing healthy and comfortable heating; electric heaters suitable for different places, which can be used as soon as they are powered on. They use independent heating chips, self-circulating air ducts, are noiseless, and have high energy efficiency. Compared with traditional electric heaters, they can save about 30% electricity; integrated top heating suitable for workshop workstations and home bathrooms. The top-mounted design is safe, energy-efficient, space-saving, pollution-free, and easy to use; convenient heating murals with obvious decorative effects. This series of graphene electric heating products can all be remotely controlled by a smart phone APP, providing safe, intelligent, and convenient control of the usage temperature. Second, a series of health products. After being powered on, the far-infrared total normal emissivity of the graphene heating film is as high as 88%, which coincides with the "life light wave" (9-16 microns) in the sun. After penetrating the human body, it can cause molecular resonance of human cells, effectively promoting blood circulation, improving metabolic capacity, enhancing the regenerative function of cell tissues, and improving the body's immunity, thus playing a health-care role. Currently, a series of wearable products have been launched, such as knee pads, waist supports, palace protectors, neck protectors, shawls, and vests, which have very good health-care effects on symptoms such as lumbar muscle strain, cervical spondylosis, arthritis, and cold palace. A graphene "sun bed" has also been launched, using 3D environmentally friendly materials and an "X"-shaped hollow three-dimensional structure to perfectly fit the human body curve, being firm but not stiff, soft but not collapsing, breathable and heat-dissipating, and moisture-proof and mildew-proof. It plays an unparalleled auxiliary therapeutic role in the professional care of the elderly and postpartum recovery care. With the continuous improvement of people's living standards and the continuous pursuit of healthy living, Taixing Technology will develop and launch more and better graphene far-infrared health products to meet people's needs.
