How to remove limescale from material and aluminum alloy

Vinegar can be eaten, vinegar is less acidic, can not corrode plastics, and will not be replaced with aluminum in aluminum alloy, the use of acetic acid acidity is stronger than carbonic acid, can remove scale (mainly carbonate caCO3, etc.). The resulting carbonic acid is unstable and releases carbon dioxide, which is non-toxic and harmless.

Limescale can be removed with white vinegar.

Ca(HCO3)2 CaCO3 +CO2 +H2OMG(HCO3)2 mgCO3 +CO2 +H2O calcium carbonate and magnesium carbonate are insoluble in water, resulting in scale.

The acetic acid in white vinegar dissolves calcium carbonate and magnesium carbonate:

caco3+2ch3cooh=ca(ch3coo)2+h2o+co2↑

mgco3+2ch3cooh=mg(ch3coo)2+h2o+co2↑

Calcium acetate and magnesium acetate are produced so that the limescale is removed.

If you don't have white vinegar, you can also use regular vinegar instead. The effect is pretty much the same.

The main components of scale are calcium carbonate and magnesium carbonate, and although dilute hydrochloric acid can remove these two metal salt scales, it will corrode some elements in titanium alloys. In order to ensure that the material is not corroded, it is recommended to use inorganic acid toilet cleaner descaler, after the scale is removed, immediately scrub with water to remove the residual descaler The composition of the scale is calcium and magnesium ions, which is easy to attach to the voids on the surface of some utensils, and will form scale in the long run. There are more than n voids on the surface of the plastic, which is easy to hide a lot of calcium and magnesium ions, that is, scale.

The method of using vinegar is relatively common and simple.

It can also be cleaned with baking soda.

Limescale? Just take the edible white vinegar at home and add it, and then wipe it with a rag. Don't put too much vinegar and cover the surface.

Hello, there are three main ways to remove rust from aluminum alloy: method 1: wipe the stain with 15% vinegar acid solution (15% tartaric acid solution is also acceptable), or soak the stained part in the solution, and rinse it with water after a few hours.

Or moisten the stained area with a 10% citric acid solution, then soak it in concentrated salt water, wash and rinse it the next day. It can also be removed by scrubbing with 2% oxalic acid solution in warm water, and then washing the clothes thoroughly with clean water to avoid oxalic acid corroding the clothing. Method 2:

Alkali acacia solution rust removal: the rust of aluminum alloy is mainly the oxide film on the surface, and sometimes there is white powder, also known as white rust, and the method of removal is mainly to remove it in an alkaline chemical solution. According to the type of material and the surface condition of the aluminum workpiece, when the surface of the aluminum workpiece has little oil stain, the degreasing and film removal can be treated together.

If the oil on the surface is very thick, the oil should be removed first, and then the oxide film should be removed, otherwise the oil removal and film removal will not be complete, which will affect the subsequent process and may reduce the quality of surface treatment. Method 3: Pickling and rust removal:

When the aluminum alloy workpiece is pickled and rust removed, the workpiece must be thoroughly degreased to ensure the quality of the rust removal. Because if the degreasing is not clean, the lead will affect the contact and reaction between the acid and the oxide film, resulting in incomplete rust removal.

Summary. How to wash off the scale of the aluminum-plastic panel.

1. We first clean the surface of the aluminum plate with a large amount of water to ensure that the stained places are wet with water.

2. Wipe the aluminum plate with a cloth soaked in detergent, and the detergent should be diluted with water in advance, otherwise it will have a certain corrosive effect on the aluminum plate.

3. Continue to wash away the foam and stains on the surface of the aluminum plate with clean water.

4. Check the surface of the aluminum plate to see if there is still ** that has not been cleaned, if so, then continue to use the above steps to clean those residual stains.

5. Use a clean cloth to wipe the remaining water stains on the surface of the aluminum plate.

Methods for removing scale from mechanical aluminum products:

1. Soak in vinegar and scrub.

2. Rinse with water.

Mechanical aluminum products] is a general term for daily necessities and industrial products made of aluminum alloy as the main raw material and processed by machinery. Among the metal varieties, aluminum is the second most common group of metals after steel. The development of the three important industries of aviation, construction and automobile requires the material characteristics to have the unique properties of aluminum cracking and ignition and its alloy, which is greatly conducive to the production and application of aluminum products.

Mix some water with white vinegar, then wipe it with a soft cloth, wipe it back and forth several times, and finally wash it off with water.

It can definitely be removed with acidic substances, and if it does not damage aluminum, you can use weak acid, vinegar in the kitchen!

The traditional way is to sand it with sandpaper, and then wipe it with a cleaning ball with detergent or glass of water, and it will shine.
