Safety  anti-fouling silicon nitride ceramic heating system Ningbo Huabiao  Engineering Technology Center scientific research team has developed a  three-year high-tech product with complete intellectual property rights.  It belongs to inorganic non-metallic materials, and its products are  mainly used in instant electric hot water faucets. ,  fast-heating electric water heater, water dispenser, instant electric  kettle, foot bath, thermostatic bathtub, quick-heat toilet seat, all  kinds of constant temperature equipment and oil field use underground  oil well heating reducer, chemical corrosion field heating, steam  generation And so on.
 The  company's team of scientific experts has gradually improved the  density, purity and flexural strength of sintered silicon nitride  products through the formulation upgrade and process reengineering from  the nitriding and processing of silicon nitride powder. The  performance is obviously superior to similar products at home and  abroad. The technology is generally in the international advanced and  domestic leading position. It has applied for a number of invention  patents and utility model patents of the State Intellectual Property  Office of the People's Republic of China, and has been included in  national and local science and technology projects. . At  present, it has brought considerable economic benefits and good social  benefits to the enterprise. It has laid a solid foundation for the  company to achieve "second take-off" in the post-crisis era, and has  taken a big step for the enterprise to achieve the goal of  transformation and upgrading.
The  safety anti-fouling silicon nitride ceramic heating element is made of  aerospace material-high-performance silicon nitride ceramic as the  carrier and embedded with special-treated high-quality tungsten wire as  the heat source. After the company's original dry pressing and cold,  etc. The static  pressure is double-molded and sintered by high temperature and high  pressure, and then processed by surface treatment. The  high-performance silicon nitride ceramic substrate is used as both a  good insulator and a good thermal conductor. It can be in direct contact  with water or other liquids to ensure rapid liquid heating, absolute  safety, environmental protection and energy saving, and excellent acid  and alkali resistance. The  flexural and compressive resistance ensures that the liquid is in an  absolutely safe state even after the product is broken due to excessive  external force under severe conditions. Therefore,  the introduction of the safety anti-fouling silicon nitride ceramic  heating element has an epoch-making significance, creating a new  situation of safe electric heating products, so that the electric  heating products originally having certain safety hazards have embarked  on an absolutely safe road. Human safety has made a positive contribution to the use of various types of electric heating products.
