Cleaning agent and cleaning method for air conditioner

Abstract

The present invention discloses a detergent and a cleaning method for a complete air-conditioner, which not only can uniformly and completely remove dirt but also cannot strongly corrupt components and parts such as aluminum, copper and stainless steel, are time-saving and labor saving, safe and reliable, and pollution-free, and have low cost. Raw materials of the detergent are at least two compositions of citric acid, inorganic weak acid and inorganic strong acid; a non-ionic surfactant or a non-ionic surfactant is mixed with an anionic surfactant; and the detergent comprises an oxygen solvent, an acid corrosion inhibitor, and the balance being water. The cleaning method comprises: disassembling a motor and a fan, and taking off the motor and the fan for independent cleaning; preparing the detergent into an aqueous solution according to the proportion of between 10 and 15 percent, hanging the complete air-conditioner after disassembly of the motor and the fan into a cleaning tank, soaking the complete air-conditioner for 30 minutes at normal temperature, and starting ultrasonic waves to clean for 10 to 30 minutes; placing the complete air-conditioner into a washing tank, and using a high-pressure water gun to spray the surface and the inside of the air-conditioner; and using hot blast to dry the air-conditioner at a temperature of 80 DEG C.

Description

Technical field: [0001] The invention relates to a cleaning agent and a cleaning method for cleaning air conditioners, in particular to a cleaning agent that can evenly and thoroughly remove dirt without causing strong corrosion to parts such as aluminum, copper and stainless steel; Safe, reliable, non-polluting air conditioner cleaning agent and cleaning method. Background technique: [0002] Air conditioners are usually overhauled after a period of operation. For example, after the train runs for 20,000 to 30,000 kilometers, the air conditioner needs to be repaired. During the inspection, the dirt on the surface of the aluminum fins in the air conditioner needs to be thoroughly cleaned to improve the heat exchange capacity of the aluminum fins, thereby improving the heating and cooling efficiency of the air conditioner. , prolong the service life of the compressor, and also need to clean the housing and other parts of the air conditioner. At present, there are two method...

Problems solved by technology

[0004] ① Strong alkaline cleaning agent has a pungent smell when sprayed, which pollutes the environment of the operation site; ② Strong alkaline cleaning agent is extremely corrosive to human skin and easily burns the operator's skin; ③ Strong alkaline cleaning agent has a strong impact on paint The coating is highly corrosive, which often causes discoloration, peeling, and peeling of the paint; ④ It is impossible to evenly reach all parts of the aluminum fins when sprayed with a strong alkaline cleaning agent, so the cleaning is uneven and the appearance appears black and white Poor; ⑤ With the thickness of the aluminum fins, it is difficult to thoroughly clean the inside of the fine aluminum fins by spraying cleaning agents; ⑥ The corrosion of the aluminum fins by strong alkaline cleaning agents is obvious, and most of the aluminum fins are cleaned after four times All will become thinner and brittle and need to be updated; ⑦The shell and other parts of the air conditioner need to be cleaned with an acidic cleaning agent, which increases the complexity of the operation and is time-consuming and laborious

[0005] 2. The pickling method generally uses ultrasonic cleaning. Due to the different acidic additives used in the cleaning agent, the cleaning effect is also different.

Some cleaning agents have a pungent smell, affecting the on-site operating environment; some produce acid mist, causing corrosion of workshop machinery and equipment; slot corrosion
