Definitions
- Thick film circuit electric heating element based on glass-ceramic substrate and preparation process thereof
- This invention relates to the field of electrical heating, and more particularly to a microcrystalline glass substrate thick film circuit controllable electric heating element and a process for its preparation.
- the new heating element requires a small volume, a large power, a large surface thermal load, a small thermal inertia, a high thermal efficiency, a low power consumption, a fast hot start, and a uniform temperature field.
- Electromagnetic pollution, green, environmentally friendly, safe and reliable In recent years, the induction cooker has been widely used in China, but the National Daily Electrical Appliance Quality Supervision and Inspection Center has done industry testing on the induction cooker products. It has found that only about 10% of the standard is reached. The biggest concern of the problem product is that it is prone to magnetic leakage. Generate electromagnetic radiation pollution. It is only the indicator of "near-area magnetic field strength". If the national standard of Switzerland, Sweden and other countries, that is, 0.2 micro Tesla, is passed, the domestic induction cooker that can pass the customs is very few.
- the bigger hidden worry is: There is no feasible and reliable standard for electromagnetic radiation pollution detection of induction cookers.
- the World Health Organization uses electromagnetic radiation such as "very low frequency electromagnetic fields" generated by induction cookers, together with benzene, welding fumes, etc. It is classified as a type of carcinogen. If there is a magnetic substance in the blood or cells, it is susceptible to magnetic induction, causing heavy metals to accumulate in the body, thereby preventing the normal activities of blood and cells from inducing cancer. And such an important test indicator, the domestic sales of induction cookers almost all "vacancy.” Unlike microwave ovens, induction cookers are unobstructed systems, and it is almost impossible to suppress electromagnetic radiation pollution. Therefore, how to study an environmentally friendly, energy-saving and safe electric heating element that can replace copper inductors without generating magnetic lines has become an urgent problem to be solved. . Summary of the invention
- the object of the present invention is to provide a low cost, high power, high thermal efficiency, low power consumption, fast hot start, and temperature field hooks in order to solve the deficiencies of the prior art, such as steel, iron, aluminum, plastic, porcelain, All kinds of tableware can be heated, and there is no thick film circuit electric heating element based on glass-ceramic substrate with electromagnetic leakage and pollution.
- Another object of the present invention is to provide a process for preparing a thick film circuit electrothermal element based on a glass-ceramic substrate.
- a thick film circuit electric heating element based on a glass-ceramic substrate comprising a substrate, a series of electronic paste, characterized in that: the series of electronic pastes are thick film circuits

Description
基于微晶玻璃基板的厚膜电路电热元件及其制备工艺 技术领域
本发明涉及电加热领域,更具体地说是涉及微晶玻璃基板厚膜电路可 控电热元件及其制备工艺。
背景技术
在我国确立的可持续发展战略中,涉及到的两个方面是环境保护和提 高能量利用率, 改善能量结构。 在电加热领域中, 新型的加热元件要求体 积要小, 功率要大, 表面热负荷要大, 热惰性要小, 热效率要高, 耗电要 低, 热启动要快, 温度场要均匀, 无电磁污染, 绿色、 环保、 安全可靠。 近年来电磁炉在我国使用较为广泛,但国家日用电器质量监督检验中心曾 对电磁炉产品做过行业摸底测试, 结果发现达标的仅 10%左右, 问题产品 的最大隐忧就是极易发生磁泄漏, 从而产生电磁辐射污染。 仅仅是 "近区 磁场强度"这项指标, 如果按瑞士、 瑞典等国的国标, 即 0.2微特斯拉为 及格线, 能过关的国产电磁炉, 廖廖无几。
更大的隐忧在于: 有关电磁炉的电磁辐射污染检测, 迄今为止没有既 可行又可靠标准, 世界卫生组织 (WHO)将电磁炉产生的 "极低频电磁场" 等电磁辐射, 与苯烯、 电焊烟雾等一起归为一类致癌物质, 如果血液或细 胞中存在有磁性物质, 就容易受磁诱发作用, 造成重金属在体内积累, 从 而妨碍血液和细胞的正常活动诱发癌症等。而如此重要的检测指标, 内销 电磁炉几乎都告 "空缺"。 与微波炉不同, 电磁炉是畅开系统, 抑制电磁 辐射污染几乎不可能, 为此, 如何研究一种可以取代铜电感线圈, 不产生 磁力线的环保、 节能、 安全的电热元件已成为人们急需解决的问题。 发明内容
