Thick Film Heaters Are More and More Popular

- Jun 30, 2020-

 The thick film heater has been attached great importance to by home appliance manufacturers. The demand for home appliance manufacturing technology has recently increased in the United States and other parts of the world. This is not to say that competitive pressures or demands for cost reduction and improved design are decreasing. On the contrary, competition has been increasing, and the selection of design components, such as heater elements and ignition devices, can sometimes become the basis of competition. The selection of a component not only takes into account the requirements of time and difficulty, but also the latest development of relevant research. To keep up with the times is a challenge, and the pace of change continues to accelerate, which can be proved in the development of computer and micro processing technology. Thick film performance appliance companies have recently developed many printed thick film heating elements. Screen printed ceramic metal components have been used in high-power products, such as irons. Another screen printing element is polymer, which is only used in low temperature equipment, such as refrigerator ice maker door body heater. Polymer thick film heater,  can be designed with low profile, so it can be bent arbitrarily to adapt to various sizes of surface. Because of its good thermal conductivity, it has been regarded as an energy-saving heat source. In processing, the image is printed by conductive charged ink through screen and resistance, and then solidified at low temperature to prevent evaporation and error. For ceramic metal components, the printed circuit should be burned at high temperature after fixing. Companies that assist thick film manufacturers to develop new technologies to solve the problem of heating equipment development. The company designed a secondary cleaning room to prevent contamination of printed parts and control the environment. The company said the cleanroom improved production, reduced waste and reduced costs. In high temperature applications, a group of thick film heaters are introduced. The strength of these heaters is up to. A total temperature control sensor is installed on the thick film to ensure fast response, good temperature control and uniform temperature distribution. Due to the need for low heat mass, the heater provides heat and the reaction can reach up to per second. This enables electrical appliances and other products to reach the required heat level quickly, thus improving efficiency and performance. The hot film technology can also be used to make low profile heaters. In fact, its trace can be printed on the screen on the substrate. The whole process only increases less than inch thickness. Various heating elements and heating outputs can be made up of a single substrate. The base materials are stainless steel, alumina, beryllium oxide, silicon carbide, aluminum nitrate and quartz. The company's electric heating products are electric kettle, iron, dryer, electric stove, humidifier, heater, hot printing head and spray gun, etc. Australian companies point out that the thin and thick heaters are different from traditional heaters in that they have uniform heat distribution on large and small surfaces, almost zero leakage in time, and they can also quickly increase temperature and low profile. After several years of continuous testing, we found that the heater can provide hours of temperature on the surface of direct porcelain cooking and hours on silicon glass. These two applications can automatically limit the temperature of the resistance film when the above temperature is reached, without cutting off the resistance film at high temperature. The research results show that it is necessary to set up a thin film heater factory and provide the manufacturer for test. The development of cookers in recent years, the main cookery factories, especially the rapid reaction glass ceramic surface furnace and high-speed furnace such as mettec, are developing rapidly. The supplier using this technology is the company. The company's vice president believes that the general trend for porcelain top furnaces is low cost and reliability. He listed a three zone heater,. The heater can use different sizes of cookers in a vitreous china surface area, not all cookers can do so, so it is regarded as an advanced stove. Radiation and helium heating elements have recently appeared in high-speed furnaces on the market. The heater is currently being developed with some manufacturers to meet their accurate needs. In terms of microwave ovens, the company is working with Sanyo to develop a new radiant heater. It can make Sanyo products reduce power output, reduce energy consumption and high efficiency, and speed up cooking time than quartz tube furnace. Tubular elements tubular electric heating elements have been used in stoves and baking pans of various sizes and shapes. Of course, manufacturers have noticed that cost is the key. The price pressure given by main equipment manufacturers due to market competition is fed back to suppliers. Suppliers must reduce costs, reduce consumption, and sometimes even reduce product performance in design. Due to the different requirements of performance, cost and stability of users, the original operation range and materials must be considered. The first is the thin-film heater, and the other is the sheath material of tubular components. The key is welding, accelerating the processing of pipe fittings, improving the thermal resistance time and reducing the material cost. Therefore, it is necessary to study new alloy materials with major raw material suppliers. This kind of alloy can be heated to dark gray and black oxidation coating, which has much stronger heat dissipation rate than green coating.
