Does stainless steel also need to be sandblasted? What is the purpose?

<> stainless steel plates, especially thicker plates.

It is a rolled plate, the surface will have defects such as color difference, scratches, etc., in the process of processing will inevitably appear new scratches, stains, etc., if the submersible treatment equipment, vacuum equipment, flow metering components, etc., in order to effectively remove these defects while ensuring the environmental protection of the production, the economic production of sandblasting is very important in the production of stainless steel.

Sandblasting can make the surface quality of stainless steel excellent and beautiful, and at the same time, improve the anti-corrosion ability through process operation.

Stainless steel liquid sandblasting is mainly for good appearance, but the cost of sandblasting is high, the sandblasting efficiency is low, and it is generally not a customer-specified requirement, so it can be dispensed with. However, in order to increase the added value of stainless steel products, more and more manufacturers have begun to use liquid sandblasting. For example, water treatment equipment industry, food machinery industry, textile machinery, pharmaceutical machinery, dyeing and finishing equipment, slaughtering equipment, beer equipment, etc., are gradually replacing pickling and liquid sandblasting.

Hello! This.

It doesn't have to be sandblasted.

Full screen of your own choices.

Generally speaking, there is no need to do sandblasting.

There may be an effect that is requested.

will be sandblasted.

Sandblasting is to treat the surface to make it more beautiful.

There are some small details that have not been handled properly, and the use of sandblasting will cover them up.

And it's even better.

It only represents a personal opinion, don't spray if you don't like it, thank you.

Stainless steel is sandblasted because the surface quality is not good-looking, and the color difference or surface effect will be good after sandblasting. Sandblasting can hide some small defects. So sandblasting.

Nowadays, because the garnet sand is hard, the Mohs hardness is above, the hardest almond garnet hardness, the hardest RZG dust-free garnet abrasive is higher than the hardness of commonly used quartz sand, sea sand, river sand and other sandblasting materials, and can go deep into the holes and uneven parts to clean, and completely remove oxide scale, rust, soluble salts and other dirt. The blasted surface is free of injectables, has no unfavorable convex points and pits, and easily obtains a SA3 blasting grade with a surface roughness of up to 30-80 m, stronger coating adhesion and longer coating life.

The surface of the stainless steel workpiece is sandblasted, and it is good to use dust-free corundum abrasive.

The surface of the stainless steel workpiece is sandblasted, and it is better to use stainless steel shots, and the surface of the polished parts is smooth and delicate, and the true color of the workpiece is retained.

After sandblasting, stainless steel reeds need to be cleaned to remove dust, impurities, oil and other debris on the surface to ensure the quality and appearance of its surface. Here are the steps to clean stainless steel blasting:

Rinse the surface with clean water. Clean the residue on the surface of the stainless steel with clean water, and you can use a high-pressure water gun or a regular faucet to rinse it to ensure that the surface is free of debris such as oil and dust.

Wash with alkaline detergent. Add an appropriate amount of alkaline cleaning agent to clean water and soak the stainless steel surface in the cleaning agent, usually the cleaning time is 10-15 minutes. The cleaning agent can remove the oil stains and metal oxides and other impurities on the surface, but pay attention to the proportion and use of the cleaning agent to avoid damage to the dust and hands on the surface of stainless steel.

Rinse the surface again with clean water. After cleaning, wash the surface with clean water to ensure that there is no cleaning agent residue on the surface.

Use an acidic cleaner for cleaning. If there is still dirt on the surface that is difficult to clean, you can use an acid cleaner to clean it. Before use, it is necessary to pay attention to the proportion and use of cleaning agent to avoid damage to the surface of stainless steel.

Finally, rinse the surface thoroughly with clean water. Make sure that there is no cleaning agent residue on the surface to avoid affecting the quality and appearance of the surface.

It should be noted that during the cleaning process, it is necessary to pay attention to protect your own safety and avoid damage to the ** and respiratory system caused by the hand cleaning agent. At the same time, it is also necessary to pay attention to the selection and use of cleaning agents to avoid damage to the surface of stainless steel.

Stainless steel needs to be cleaned after sandblasting to remove residual sand, sand, and other impurities, while also increasing the finish and aesthetics of the stainless steel surface. Here are the steps after cleaning stainless steel sandblasting:

Rinse with water: Rinse the stainless steel surface with clean water to remove most of the sand and impurities.

Use Cleaner: Apply the cleaning agent to the surface of the stainless steel and gently scrub with a soft-bristled brush or sponge to remove residual dirt and grit.

Rinse again: Rinse the stainless steel surface again with clean water to thoroughly wash off the cleaning agent and any remaining dirt.

Drying: Dry the stainless steel surface with a clean towel or paper towel, or allow it to dry naturally.

It is important to avoid using too acidic or alkaline cleaning agents during the cleaning process to avoid damage to the surface of the stainless steel. At the same time, when cleaning the stainless steel surface, it is also necessary to pay attention to the use of soft tools to avoid scratches and damage to the stainless steel surface.

After sandblasting, stainless steel can be washed with clean water or with steam. If you are using steam for cleaning, pay attention to adjusting the pressure to the appropriate level to avoid damage to the stainless steel surface. In addition, special tools or chemicals can be used to help quickly and accurately remove trash from stainless steel.

In short, if you want to ensure that stainless steel has a bright and durable skin after sandblasting, it must be cleaned thoroughly and correctly.

Garnet sand for stainless steel sandblasting.

Nowadays, garnet sand is more used, because the garnet sand has a hard texture, Mohs hardness is above, the hardest al-aluminum garnet hardness, and the hardness of RZG dust-free garnet abrasives is higher than that of commonly used quartz sand, sea sand, river sand and other sandblasting materials, which can go deep into the holes and uneven parts for cleaning, and completely remove oxide scale, rust, soluble salts and other dirt. The blasted surface is free of embeddings, unfavorable bumps and pits, and can easily obtain a SA3 blasting grade, with a surface roughness of 30-80 m, improved coating adhesion and a longer coating life.

The main role of stainless steel sandblasting:

1. Polishing the surface of stainless steel to make the surface more beautiful.

Sandblasting can be used to achieve different reflective or matte finishes of stainless steel. Such as stainless steel surface matte, surface pattern, and texturing processing.

2. Limb elimination belt skillfully removes stress and strengthens the surface.

The stainless steel surface is struck by sand shot to relieve stress and increase the surface strength of the stainless steel. <>

1. Mechanical polishing: mechanical polishing is a polishing method that relies on cutting, plastic deformation of the surface of the material to remove the convex part after being polished and obtain a smooth surface, generally using oil stone strips, wool wheels, sandpaper, etc., mainly manual operation, special parts such as the surface of the rotary body, can use auxiliary tools such as turntables, and the method of ultra-fine grinding and polishing can be used with high surface quality requirements. Superfinishing grinding and polishing is the use of special abrasives, in the grinding and polishing liquid containing abrasives, pressed on the surface of the workpiece to be processed, for high-speed rotary motion.

The surface roughness that can be achieved with this technology is the highest among all polishing methods. This method is often used in optical lens molds.

2. Chemical polishing: Chemical polishing is to make the microscopic convex part of the surface of the material in the chemical medium preferentially dissolve the concave part, so as to obtain a smooth surface. The main advantage of this method is that it does not require complex equipment, it can throw simple and large light workpieces with complex shapes, and can polish many workpieces at the same time, with high efficiency.

The core problem of chemical polishing is the preparation of polishing slurry. The surface roughness obtained by chemical polishing is generally 10 m.

3. Electrolytic polishing: The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, the surface is smooth by selectively dissolving the tiny protruding parts of the surface of the material. Compared with chemical polishing, it can eliminate the shadow of the cathodic reaction, and the effect is better.
