Piastra di riscaldamento a pellicola spessa quadrata
Square thick film heaters are widely used in household appliances such as water dispensers, caffettiere, and rice cookers. Thick film process performance is superior to traditional heating tube heating methods; it has the following advantages:
1. Piccola dimensione; the square thick film heating plate has a very small size, which allows it to be easily installed in various household appliances without affecting the entire device.
2. Velocità di riscaldamento elevata; the square thick film heating plate has a very fast heating speed, which can heat the equipment to the required temperature in a short time, saving the user’s time and electricity bills.
3. Lunga vita; Because the square thick film heating plate adopts modern materials and manufacturing processes, it has a very long life and can be used continuously for many years, reducing the maintenance and replacement costs of household appliances.
4. Alta efficienza termica; the thermal efficiency of the square thick film heating plate is very high, which can maximize the efficiency of converting electrical energy into thermal energy, thereby making the heating effect of the equipment faster and more stable.
5. Safe and environmentally friendly; the square thick film heating plate is also a very safe and environmentally friendly heating technology. It generates uniform heat and precise temperature control, which can avoid safety hazards such as equipment overheating or leakage. Allo stesso tempo, it does not emit harmful substances and is harmful to the environment. Will not cause pollution.
Stainless steel substrate
The EU stipulates that the chromium content of steel used in the food industry must reach 12%. Steel with a chromium content of less than 12% cannot be called stainless steel. Tipo 304 stainless steel has a higher expansion coefficient (TCE about 18 ppm/℃) while type 430 stainless steel has an expansion coefficient of about 12 ppm/℃.
Uncoated stainless steel substrates must be cleaned of contaminants (come le impronte digitali, polvere, olio, grasso, ecc.), and gloves must be worn when touching the stainless steel substrate again after cleaning.
Sintering process
Sintering atmosphere: air atmosphere
The sintering process includes: 200℃-300℃ is the volatilization or sintering of organic solvents and resins
The unsintered resin in the slurry is sintered at 300℃-500℃
The bonding phase in the slurry begins to soften at 600℃-800℃
The bonding phase in the slurry is sintered and dense at 800℃-850℃
Applications of square thick film heaters:
1. Medical field: Square thick film heaters are widely used in the medical industry. For example, hospitals will use it to heat infusion sets or items used in surgeries to keep their temperatures stable and improve surgical safety and patient comfort.
2. Environmental protection field: Square thick film heaters are used in heating treatment facilities or solutions in the environmental protection industry. For example, during the sludge drying process, it can instantly heat the temperature to over 100°C, thereby reducing the volume and harming the environment.
3. Processing fields: Square thick film heaters can also be used in the processing industry. For example, used to heat a tool or material surface to make it easier to cut or process into a final product
