Embodiment Construction

[0019] Use the following weights of raw materials to prepare 100 kg of cleaning agent for condenser tubes:

[0020] Fatty alcohol polyoxyethylene ether AEO—10 7 kg;

[0021] Fatty alcohol polyoxyethylene ether JFC 6 kg;

[0022] Isomerized alcohol ether E-1306 4 kg;

[0023] Polyoxyethylene fatty acid ester LAE—24 8 kg;

[0024] Fatty alcohol ether phosphate potassium salt MOA3PK 6 kg;

[0025] Sodium silicate 0.3 kg;

[0026] 68.7 kg of water.

[0027] First heat and melt fatty alcohol polyoxyethylene ether AEO-10, fatty alcohol polyoxyethylene ether JFC and fatty alcohol ether phosphate ester MOA3PK, then add hot water and stir evenly; in the stirred solution, polyoxyethylene fatty acid ester LAE -24 and isomeric alcohol ether E-1306 and keep stirring; dissolve the sodium silicate with a small amount of water first, then add it into the stirring solution, and add water to the formula amount, then the pH value is 7-8.5.

[0028] Use the cleaning agent above to clean the...

Abstract

The invention discloses a method for cleaning a condenser tube, which relates to the field of industrial cleaning technology, and uses cleaning agent which is made from fatty alcohol-polyoxyethylene ether AEO-10, fatty alcohol-polyoxyethylene ether JFC, heterogeneous alcohol ether E-1306, polyoxyethylene fatty acid ester LAE-24, fatty alcohol ether phosphate potassium MOA3PK, sodium silicate and water, wherein the cleaning agent is added in a 40DEG C-50DEG C ultrasonic wave warm water pool, the weight ratio of the cleaning agent and water in the ultrasonic wave warm water pool is 1:60, and the condenser tube is placed in the ultrasonic wave warm water pool, and is soaked in liquid with ultrasonic vibration for 1-1.5 minutes, is taken out from the ultrasonic wave warm water pool after being soaked, and can be orderly placed into two cold water pools to be cleaned by water. The method for cleaning the condenser tube is strong in dirt-removing power, excellent in cleaning effect, low in temperature of cleaning water, is beneficial for energy conservation, is less in usage of the cleaning agent, and low in cost.

Description

technical field [0001] The invention relates to the technical field of cleaning industry cleaning, in particular to a cleaning method for cleaning metal products. Background technique [0002] Condenser tubes are pipe fittings set in the condenser, which are mainly used for the circulating flow of cooling liquid, so as to realize the refrigeration of the condenser. In the process of manufacturing the condensing air pipe, the pipe body is prone to dust and oil stains. These dirt will not only affect the heat transfer coefficient and reduce the cooling effect, but also affect the welding quality of the pipe fittings in the subsequent welding process. If the condenser tubes are not cleaned cleanly, oxidation will occur after welding, causing black spots on the surface. An existing cleaning method for cleaning condenser tubes is to use decloning for cleaning. This cleaning agent has a good cleaning effect, but it contains toxic substances and is harmful to human health and the ...
