Embodiment 1
[0035] Air conditioner fin cleaning agent is made from the following components in weight percentage: 10kg of nitric acid, 0.5kg of potassium chromate, 0.5kg of AES, 50.1kg of OP-50.1kg, and 88.9kg of water.
[0036] Preparation:
[0037] a. Take half of the amount of water, add nitric acid while stirring at room temperature, and then stir for 3 minutes after adding, to obtain aqueous solution a;
[0038] b. Take the other half of the water, heat it to 50°C, add potassium chromate, AES, OP-10 in turn, stir well until the solid particles are completely dissolved, then cool it to room temperature to obtain the aqueous solution b.
[0039] c. Slowly add the uniformly stirred aqueous solution a into the aqueous solution b, stir thoroughly for 3 minutes until uniform, and the finished product is prepared.
Embodiment 2
[0041] The cleaning agent for air conditioner fins is made from the following components in percentage by weight: 13kg of nitric acid, 0.6kg of potassium chromate, 0.7kg of AES, 60.3kg of OP-6, and 85.4kg of water.
[0042] Preparation method: the stirring time in step a is 4 min; the heating temperature in step b is 55° C.; the stirring time in step c is 4 min; the others are the same as in Example 1.

Abstract
The invention belongs to the technical field of metal surface cleaning and in particular discloses an air conditioner fin cleaning agent and a preparation method thereof. The cleaning agent is mainly prepared by mixing water and the following components by weight percentage: 10 to 15 percent of nitric acid, 0.5 to 0.8 percent of potassium chromate, 0.5 to 0.8 percent of sodium ethoxylated alkyl sulfate, and 0.1 to 0.5 percent of polyoxyethylene octylphenol ether. The preparation method comprises the following steps: taking water in half of the amount, adding the nitric acid into the water, and uniformly stirring the nitric acid and the water to obtain an aqueous solution a; taking the other half amount of water, sequentially adding the potassium chromate, the odium ethoxylated alkyl sulfate and the polyoxyethylene octylphenol ether into the water, fully stirring the mixture till solid particles dissolve completely, and obtaining an aqueous solution b; and slowly adding the uniformed stirred aqueous solution a into the aqueous solution b, fully stirring the aqueous solution a and the aqueous solution b till the mixed solution is uniform, and obtaining a finished product. The cleaning agent is excellent in cleaning and energy-saving effect and avoids corrosion influences on equipment surface substantially.
Description
technical field [0001] The invention belongs to the technical field of metal surface cleaning, and in particular relates to an air conditioner fin cleaning agent and a preparation method thereof. Background technique [0002] In public places, institutions, hotels, schools, enterprise workshops, etc., after long-term operation of various air-conditioning equipment equipped with aluminum cooling fins, fibers, dust, oily smoke and other dirt will adhere to the fins, blocking the air passage and increasing energy consumption. Condensed water in summer provides a living environment for bacteria and mold to multiply, producing disgusting stench and musty smell, resulting in a decrease in the quality of the air environment, causing nausea, dizziness and other symptoms to people in the environment, so these air conditioners The fins of the equipment should be cleaned in time. [0003] At present, the air-conditioning fin cleaning products used in the market are basically strongly ...
