How to remove oil stains from machined aluminum parts?

Heavy oil cleaner masterbatch.

Heavy oil cleaner masterbatch + flavor + pigment + preservative + water = heavy oil cleaner.

Heavy oil cleaning agent masterbatch is the latest research and development of Chengdu Hengfeng Hongye detergent factory specially used for heavy oil, heavy pollution, heavy dirt and heavy dirt cleaning agent special effect core masterbatch, with the following characteristics:

2. Production yuan one pound formula: dosage per 100 catties: kilogram of heavy oil cleaning agent masterbatch + water + pigment 1 gram + preservative 10 grams + flavor 5 grams.

3. Production yuan one pound formula: dosage per 100 catties: kilogram of heavy oil cleaning agent masterbatch + water + pigment 1 gram + preservative 10 grams + flavor 5 grams.

4. The formula for the production of one catty: the dosage per 100 catties: kilogram of heavy oil cleaning agent masterbatch + water + 1 gram of pigment + 10 grams of preservative + 5 grams of flavor.

5. The formula ratio of other prices is calculated by yourself, and the formula proportion adjustment principle is to determine the cost of pigments, preservatives and flavors first, and finally determine the amount of heavy oil cleaning agent masterbatch.

6. Dosage per 100 catties: heavy oil cleaning agent masterbatch + water.

7. How to ensure quality: The quality should be combined with the shelf life you need, the variety and content of preservatives, the cleanliness of water quality, the cleanliness of production tools and packaging, the changes in the climate of the four seasons and other factors to be comprehensively determined.

8. Special needs: high-consistency four-in-one thickener is required, and high-foaming concentrate is required.

Ultrasonic cleaning can be used to clean oil stains well.

Wash with lye, and the popular point is soapy water.

Special metal cleaning agent or wiping machine water with ultrasound machine cleaning is better.

After the processing of die-cast aluminum alloy parts, the method of cleaning the surface oil stains:

The special cleaning agent for aluminum alloy is mainly prepared by high-quality surfactants, penetrants, corrosion inhibitors, special cleaning additives, etc., which is suitable for cleaning between machining processes, and has good cleaning performance and high cleaning degree for cutting oil, emulsified oil and stamping oil on the surface of the workpiece. At the same time of cleaning, it can effectively protect the surface of the cleaned material from erosion.

Characteristics: 1. It has strong osmosis, dispersion, solubilization and emulsification.

2. Weak acid degreasing, fast decontamination and degreasing, and good cleaning ability for grease and dirt. Long service life, good corrosion inhibition, no corrosion to the substrate.

3. It is completely dissolved, easy to operate and easy to rinse.

Aluminum alloy surface faded? Does it mean that the surface of the aluminum alloy is atomized? Theoretically speaking, there is no effect on the metal surface without pickling and alkali washing, you can use isopropanol or acetone to deal with it, but you need some special equipment, otherwise these things are toxic and volatile, you can look at those low-temperature organic solvent cleaning equipment, which should help you.

Answer: Organic solvents have a strong dissolving effect on both saponified and non-saponified oils, and can remove marking symbols and residual polishing paste on the surface of the workpiece. The main target is non-saponified oil pollution.

The methods of organic solvent degreasing include scrubbing, immersion, spraying, ultrasonic cleaning, etc. Among them, the oil cleaning agent is selected for ultrasonic cleaning, which has the characteristics of high efficiency and good clear effect of oil stain, especially for some workpieces with complex shapes, fine holes, blind holes and high requirements for oil removal, which is a commonly used organic solvent cleaning method.

Features: The degreasing speed is fast, and it generally does not corrode the metal, but it is not very thorough to remove heavy oil stains, and it must be further cleaned by chemical or electrolytic methods.

Chemical degreasing is used to remove invisible oil stains, surface dust, trace amounts of rust barriers, and some small contaminants formed during transshipment or production. Chemical degreasing includes alkaline chemical degreasing and acidic chemical degreasing.

1.Alkaline chemical degreasing.

Alkaline degreasing is one of the most commonly used methods, and its degreasing principle is to achieve the purpose of removing these two types of oil with the help of the saponification effect of lye on saponified oil stains and the emulsification effect of surfactants on non-saponified oil stains. 2.Acid chemical degreasing Acid degreasing treatment is also a widely used degreasing method, acid degreasing agent is generally composed of inorganic or organic acids, surfactants, corrosion inhibitors and penetrants.

Features: No need to heat, can have a good degreasing effect at room temperature. If heated to about 40, the degreasing effect can be significantly improved; Hard PVC can be used for the working cylinder at room temperature degreasing, and PP should be used for heating and degreasing.

3. Alkaline electrodegreasing is rarely used for electrodegreasing aluminum alloy degreasing, because this type of cleaning treatment has a greater erosion effect on the surface of the parts, and the equipment investment is also large.

Characteristics: It has great activity and purity. Electrodegreasing is divided into cathodic degreasing and anodic degreasing. Most use cathodic degreasing.

1. The time for the aluminum tip to be stained with oil is relatively short, and it can be wiped with a rag dipped in alcohol, and the time for staining with oil is longer, so you need to wipe it vigorously with a scouring pad first, and then wipe it carefully with a rag dipped in alcohol or dish soap, and the oil stain can be removed.

2. One of the advantages of aluminum products is that they are easy to take care of, similar to some stains or watermarks, etc., which can be wiped clean at once, but if they are stained with oil, it will be difficult to take care of them for a long time, so we must remove them in time so as not to affect the appearance.

3. If the oil stain has just been stained not long ago, we can wipe it with alcohol, and when the first wipe is completed, we should take a closer look at the place with better light, if there are still shallow marks, we should wipe it several times, and then wash it with water after it is clean.

4. If it is the kind of oil stain that lasts for a long time, you need to buy a scouring pad in the supermarket, and then wipe it vigorously in the place with oil stains, and then wipe it carefully with a clean rag dipped in alcohol or dish soap, and check it again after wiping.

<>1. Wipe the oil stain on the surface of the aluminum alloy with a clean cotton cloth, then pour a small amount of vinegar and detergent into clean water and stir evenly, and wipe it repeatedly with a cotton cloth dipped in the solution.

2. You can use professional aluminum alloy cleaning agent to deal with oil stains.

3. Spray the organic solution on the oily aluminum alloy, wipe it repeatedly and then scrub it with water.

Aluminum is an amphoteric metal, both afraid of alkalinity, and afraid of acid, the use of alkaline degreaser will leave a little ash on the surface more or less after degreasing, and then through a 40% nitric acid aqueous solution impregnation (known as the light) after the light, you can get a clear and white surface.

If you want to remove the oil without affecting the original appearance, the best way is to clean it with organic solvents, such as aviation gasoline, alcohol, acetone, etc. But the cost will be higher.

If you only pay attention to removing the oil stain, allow a little discoloration, and do not want to increase the light process, you can choose to use low temperature and room temperature degreasing agent to clean in a special ultrasonic cleaning machine. In addition to a small amount of alkali and alkaline salts, this kind of industrial degreaser has more surfactants, which has a good degreasing effect on a variety of oil stains, and less damage to the surface of the workpiece, which is much better than the effect of laundry detergent and soap powder.
