Description
Technical field
The present invention relates to it is a kind of be used to cleaning the cleaning agent and cleaning method of air-conditioning, especially one kind can uniform and complete go
Dirt, and deep-etching will not be produced to aluminum fin-stock；It is time saving and energy saving, cost is low, safe and reliable, free of contamination air-conditioning aluminum fin-stock is weak
Alkaline cleaner and cleaning method.
Background technology
Air-conditioning will carry out overall maintenance usually after a period of time is run to it, as train is running 20,000 to 30,000 kms
Just need to overhaul air-conditioning after mileage.The dirt on thoroughly aluminum fin-stock surface in cleaning air-conditioning is needed during maintenance, to improve aluminum fin-stock
Heat-exchange capacity, so as to improve the heating of air-conditioning, refrigerating efficiency, extends the service life of compressor, while is also required to air-conditioning
Shell and other parts cleaned.At present, the cleaning for air-conditioner fin has alkali wash and acid wash two ways,
It is different degrees of that there are the following problems.
1. general in cleaning agent used in alkali wash contain caustic soda 10~30%, pH value reaches more than 13, by strong basicity during cleaning
Cleaning agent stoste or 25~50% aqueous solution are uniformly sprayed on aluminum fin-stock, stop 5min, then rinse aluminum fin-stock with giant
Dirt in gap.1. strong basicity cleaning agent has sharp aroma, pollution operation site environment in sprinkling；2. strong basicity cleaning agent
It is extremely strong to the corrosivity of human skin, the skin for the operator that easily burns；3. strong basicity cleaning agent has painting layer very strong
Corrosivity, often results in paint discoloration, aliquation, stripping etc.；4. corrosion of the strong basicity cleaning agent to aluminum fin-stock is obvious, most of aluminium
Fin clean four times after all by it is thinning, become fragile, it is necessary to update.
2. acid wash generally uses ultrasonic cleaning, due to cleaning agent used by acid additive it is different, cleaning performance
Differ.Some cleaning agents have sharp aroma, influence execute-in-place environment；Some generation acid mists, cause room machine equipment to send out
Get rusty erosion；Corrosivity also is too strong, causes the subsidiary stainless steel of air-conditioning, copper pipe and ultrasonic cleaner to corrode.
The content of the invention
The present invention is to solve the above problem present in the prior art, there is provided one kind can uniform and complete go to decontaminate
Dirt, and deep-etching will not be produced to aluminum fin-stock；Time saving and energy saving, of low cost, safe and reliable, free of contamination air-conditioning aluminum fin-stock weak base
Property cleaning agent and cleaning method.
The present invention technical solution be：A kind of air-conditioning aluminum fin-stock alkalescent cleaning agent, it is characterised in that contained raw material
And mass percent is as follows：Citric acid 1~5%；Metasilicate pentahydrate sodium 0.1~15%；Sodium carbonate 0.1~5%；Sodium gluconate
0.1~10%；Nonionic surfactant 0.5~20%, cationic surfactant 0.5~10%；Oxo solvent 0.5~
15%；Water surplus；PH value 10.0~10.5.
The nonionic surfactant is octyl phenol polyoxyethylene ether or nonylphenol polyoxyethylene ether or laruyl alcohol polyoxy
Vinethene.
The cationic surfactant is dodecyl trihydroxyethyl ammonium.
The oxo solvent is ethylene glycol, 1,2- propane diols, isopropanol, ethylene glycol phenyl ether, butyl glycol ether, ethylene glycol ethyl ethers
At least one of ether, butyl, diethylene glycol ether, ethylene glycol isobutyl ether.
A kind of air-conditioning aluminum fin-stock cleaning method, carries out in accordance with the following steps：
A. the aluminum fin-stock on train air-conditioning is dismantled；
B. cleaning agent 10~15% is made into aqueous solution by mass percentage, the air-conditioning aluminum fin-stock of dismounting is hung in rinse bath, often
The lower immersion 30min of temperature, opens 10~30 min of ultrasonic cleaning；Air-conditioning aluminum fin-stock is placed in rinsing bowl, with giant hydro-peening
Air-conditioning aluminum fin-stock surface and gap；
C. airing is placed.
The present invention is using inorganic salts as alkalescent builder, and cationic surfactant increases permeability, each group split-phase
Mutually coordinate, can uniform and complete remove air-conditioning aluminum fin-stock surface smut, to improve the heating of air-conditioning, refrigerating efficiency；In pH value 10.0
Under~10.5 weak basic condition, the excessive erosion of aluminium, copper and stainless steel can be also prevented, it is time saving and energy saving, cost is low；The present invention does not produce
It is raw acid mist, nontoxic, have no effect to operating environment and human body, securely and reliably.
