Abstract
The invention provides a cleaning method for a silencer. The produced as-cast silencer is cleaned through ultrasonic wave with the temperature being 55-65 DEG C for 45-120 seconds, the silencer is cleaned for three times, and an alkaline detergent is added to ultrasonic water; rinsing is conducted through pure water; the silencer is rinsed through water with an alkaline rust remover added therein for 45-120 second and for twice; rust removal treatment is connected with the alkaline rust remover for 45-120 seconds; cleaning is conducted through pure water; air drying is conducted; and baking is conducted. According to the cleaning method for the silencer, a combined chemical and physical method is adopted, the alkaline detergent is combined with the ultrasound, and residual acid on the surface of the silencer can be effectively removed; then the water with the alkaline rust remover added therein is used for rinsing, it is further ensured that acid liquor is completely removed. Moisture in the technological process of the whole process is evaporated through air drying and baking, the surface of the silencer is ensured to be clean, the silencer is made to work well, and the noise defending effect is better.
Description
Technical field
The present invention relates to a kind of metal material surface protection field, particularly relate to a kind of purging method of sourdine.
Background technology
Sourdine is that accessory commonly used by domestic air conditioning and central air-conditioning, be generally used for control air power noise, its principle is the sound reflection effect utilizing device acoustical behavior sudden change place in the duct, resonator is connect by the unexpected expansion of pipeline section, contraction or side, produce acoustic impedance mismatch, the phenomenons such as the interface that the sound wave of some frequency is suddenlyd change in specific acoustic resistance is reflected, interference, thus reach the object of noise elimination.
The sourdine that air-conditioning uses in the preparation, starting material often have oxidative phenomena, there is certain rust staining, and in processing preparation process, starting material of being everlasting are coated with lubricating oil, antirust wet goods, the finished product sourdine that processing obtains can remain greasy dirt, also there is certain rust staining, directly be installed in compressor of air conditioner, can affect the operation of sourdine, noise-proofing effect reduces.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of removing method of sourdine is provided, effectively can remove greasy dirt and the corrosion on sourdine surface, make sourdine surface keep clean, ensure the good operation of sourdine, make noise-proofing better effects if.
The present invention is achieved in that
A purging method for sourdine, comprises the following steps:
Step 1, the black embryo sourdine ultrasonic wave produced cleaned, the temperature of cleaning is 55-65 DEG C, and scavenging period is 45-120 second, cleans three times, wherein adds alkalis in ultrasonic water;
Step 2, pure water rinsing;
Step 3, the water adding alkaline deruster of the sourdine after step 2 being processed carries out rinsing 45-120 second, rinsing twice;
Step 4, the sourdine alkaline deruster after step 3 being processed carries out antirust treatment 45-120 second;
Step 5, the sourdine pure water after step 4 being processed cleans;
Step 6, air-dry;
Step 7, dries.
Preferably, in step 1, the concentration of ultrasonic water neutral and alkali washing composition is 0.1 ~ 10wt%, is more preferably 1 ~ 8wt%, is more preferably 3 ~ 5wt%.
Preferably, in step 3, the concentration adding the water neutral and alkali rust remover of alkaline deruster is 0.1 ~ 10wt%, is more preferably 1 ~ 8wt%, is more preferably 3 ~ 5wt%.
Preferably, in step 3, the temperature of rinsing is 40 ~ 80 DEG C.
Preferably, in step 5, the temperature of oven dry is 130 ~ 160 DEG C, and drying time is 6 ~ 10 minutes.
In foregoing of the present invention, alkaline cleaner refers to the clean-out system that pH value is greater than 7.
In foregoing of the present invention, alkaline deruster refers to the rust remover that pH value is greater than 7.
The present invention adopts the method for chemistry and physical bond, adopts alkalis and combination of ultrasound effectively can remove the greasy dirt on sourdine surface, then adopts the water adding alkaline deruster to carry out rinsing, further ensures the clean of sourdine surface.In whole technique, adopt method that is air-dry and that dry by the water evaporates in technological process, new impurity can not be introduced on sourdine surface.Adopt purging method provided by the invention can effectively remove greasy dirt and corrosion, ensure sourdine surface clean, make sourdine operational excellence, noise-proofing better effects if.
