Abstract

The invention relates to a method for cleaning a glass sealed diode structure NTC thermistor. The method comprises the steps of evenly mixing 290-310g of tea seed powder, 190-310g of edible alkali and 90-110g of sodium phosphate to form a cleaning agent; utilizing 4.5-5.5 L of hot water at 80-90 DEG C to mix with the cleaning agent, performing mixing to completely dissolve the cleaning agent, and performing filtration; pouring the cleaning agent in an ultrasonic wave tank, performing cleaning at 50-60 DEG C by being matched with ultrasonic waves; utilizing water to perform flushing cleanly after cleaning, and performing drying. The tea seed powder serves as a main raw material in the cleaning agent raw materials, can generate foam and perform soaking to remove oil and is good in oil removal effect; by adding the edible alkali and sodium phosphate, emulsification penetration can be accelerated, and the cleaning process is accelerated; by utilizing ultrasonic wave cleaning, the cleaning effect can be reinforced, and the cleaning speed can be accelerated. After the tea seed powder is made into the solution, the solution has tea aroma and can be in direct contact with hands, and an aromatic safe operating environment is provided for operating workers; and pollution to atmosphere soil and water bodies is avoided. According to the method, the operating environment is simpler, the problem that white gas and alcohol are flammable and explosive and may cause fire accidents and the like is solved, and the method is safe to use.

Description

technical field [0001] The invention relates to a cleaning method for an NTC thermistor with a glass-sealed diode structure. Background technique [0002] The existing NTC thermistor with glass-sealed diode structure needs to be tested in methyl silicone oil. At present, the main cleaning method is to clean it in white electric oil, and then rinse it in alcohol. White electric oil has a good oil-dissolving effect and is widely used in industrial cleaning. However, white electric oil has a pungent smell, which is harmful to the body, pollutes the soil and the atmosphere, and is not conducive to environmental protection; white electric oil and alcohol are both flammable and explosive. products, there are potential safety hazards. Contents of the invention [0003] The object of the present invention is to aim at above-mentioned present situation, aims to provide a kind of cleaning method of NTC thermistor of glass-encapsulated diode structure that is harmless to human healt...
