Excuse me, does sanding damage the body?

Damage to the body, mainly pneumoconiosis. But as long as you wear your own protective mask, it's not a big deal.

Pneumoconiosis is a fibrotic disease of the lungs, in which patients usually stay in places full of dust or garbage accumulation for a long time, due to inhalation of a large amount of dust, resulting in the accumulation of dust in the alveoli under the peripheral bronchi, and after a period of time, changes in the lungs form fibrosis silicosis.

It is mainly caused by the inhalation of crystalline silicon dust by the human body, and the main components of crystalline silicon are mainly soil, sand, granite and other rock components. The main symptoms are: shortness of breath, fever.

Tiredness, loss of appetite, chest pain, dry cough, decreased breathing, and possibly death. It can also cause other pathologies, including lung cancer and bronchitis.

Chronic obstructive pulmonary disease, tuberculosis scleroderma, and even kidney disease.

If there is damage, 1: vibration will be generated during operation, and long-term contact will cause damage to muscles, joints, bones, etc.; 2. Noise, hearing damage, 3. Dust will be produced during operation, which will cause great damage to the lungs, such as pneumoconiosis, etc.!

It must be harmful to the body, especially the dust from the grinding is very large, if you really do this work, you have to check your lungs regularly

Of course, there is a danger of pneumoconiosis.

It depends on the conditions under which the sand is made, and you can also analyze the conditions under which you can bear it.

For sure, it's very damaging to the lungs.

Harmless, but compared with the glossy, sanded kitchen and bathroom products will be relatively easier to hide dirt and dirt, nuclear search in the health considerations, or not recommended. In addition, if you do your own sanding, it is best to wear a mask and protective eye opening glasses.

The dust generated during sanding is harmful to the human body.

Sandblasting operation, there is a large amount of dust in the air in the working environment, improper protection, easy to lead to pneumoconiosis.

In the current society, for example, there are often cases of workers wearing protective equipment and still suffering occupational injuries, which can be summarized as follows.

1. Use gauze masks as dust masks.

2. The protection level cannot meet the protection requirements.

3. The product is a counterfeit product.

4. Improper selection of products.

It is recommended to choose a dust mask through the following aspects to avoid pneumoconiosis injury.

1. Dust masks belong to special labor protection equipment, which must pass GB2626-2006 "Respiratory Protection Equipment-Self-priming Filtering Anti-particulate Respirator".

2. According to the national standard, protective masks are divided into oil-proof (oily smoke, oil mist, dust, smoke, microorganisms) and anti-non-oily particles (dust, smoke, fog, microorganisms: bacteria, spores), etc.

3. According to the protection level, it is divided into KN100, KN95, KN90 and KP100, where the following numbers represent the protection rate of ultrafine particles. Of these, 100 represents the protection rate or above.

4. According to the national standard, the mask is divided into three types: large, medium and small.

5. According to the national standard, the mask is divided into two types: from the bridge of the nose to the chin (one-quarter type) and from the bridge of the nose to the jaw (one-half type). Half of them are more comfortable.

6. According to the national standard, the mask is divided into one-time, duplex half-mask, and full-face mask. Among them, the duplex half mask is more suitable for long-term occupational dust protection.

Note: At present, pneumoconiosis is frequent, and it cannot be medical**, bringing extreme harm to patients and families, for the sake of your and my health, we must pay attention to respiratory protection, correctly choose respiratory protective equipment, and avoid the harm of pneumoconiosis.

For sandblasting operations, the dust concentration is very good, and it is recommended to choose a duplex silicone N100 grade dust mask. It can eliminate dust damage.

This kind of work should be well protected and careful.

It is necessary to wear a dust mask, if there is no protective measures, it will definitely cause harm to the lungs, and long-term operation in a closed environment will lead to pneumoconiosis.

They are more tired, ordinary workers may be exposed to less harmful gases, and welders are more technical.

May I ask if any of you have come to the boat to paint? If so, please contact me.

The main thing is that dust pollution has an impact on people's respiratory organs, so there must be dust removal equipment.

Sand blowing is the process of using compressed air as the power and using the impact of high-speed sand flow to clean and roughen the surface of parts. Spraying is generally quartz sand, emery, iron sand, etc., spraying in the process of impact and cutting on the surface of the workpiece, so that the surface of the workpiece obtains a certain cleanliness and different roughness, however, the sand will also be broken, dust, blowing sand is harmful to the body is mainly dust pollution, if you wear a good dust mask, do a good job of labor protection, there is no big problem, if the labor protection is not done, it will cause damage to the body for a long time, mainly silicosis, is an occupational disease. There is no problem with working for a short period of several years and taking good care of the labor protection.

The effects of sanding are as follows:

1) Workpiece coating, workpiece bonding pre-treatment sandblasting can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic schema on the surface of the workpiece (that is, the so-called rough surface), and can be replaced by different particle size of abrasives.

For example, the abrasives of Feizhan abrasives reach different degrees of roughness, which greatly improves the adhesion between the workpiece and the coating and plating. Or make the adhesive bond stronger and better quality.

2) The cleaning and polishing of the rough surface of the casting and the workpiece after heat treatment can clean all the dirt (such as oxide scale, oil and other residues) on the surface of the casting and forging and the workpiece after heat treatment, and polish the surface of the workpiece to improve the finish of the workpiece, so that the workpiece can expose a uniform and consistent metal color, so that the appearance of the workpiece is more beautiful and good-looking.

3) Burr cleaning and surface beautification sandblasting of machined parts can clean the tiny burrs on the surface of the workpiece, and make the surface of the workpiece more flat, eliminate the harm of burrs, and improve the grade of the workpiece. And sandblasting can make a small fillet at the junction of the surface of the workpiece, making the workpiece appear more beautiful and more precise.

4) Improve the mechanical properties of parts, after sandblasting, mechanical parts can produce uniform and fine concave and convex surfaces on the surface of parts, so that lubricating oil can be stored, so that the lubrication conditions can be improved, and noise can be reduced and the service life of machinery can be improved.

5) Decorative effect: For some special-purpose workpieces, sandblasting can achieve different reflections or matte at will. Such as the polishing of stainless steel workpieces and plastics, the polishing of jade, the matte surface of wooden furniture, the pattern of the surface of frosted glass, and the texturing of the surface of cloth.

Sandblasting is the use of compressed air as the power to form a high-speed jet beam to spray (shot peening glass beads, steel shots, steel sand, quartz sand, emery, iron sand, sea sand) to the surface of the workpiece to be treated at high speed, so that the mechanical properties of the outer surface of the workpiece surface change, due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, so that the fatigue resistance of the workpiece is improved, It increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating, removing the impurities, variegation and oxide layer on the surface, and at the same time roughening the surface of the medium, making the residual stress on the surface of the substrate and improving the surface hardness of the substrate.

Uses of sandblasting:

1. Cleaning of the surface of the workpiece.

Oxide scale, residual salt, residual oil, etc. after heat treatment; oxide scale, molding sand, etc. of black (have) color castings; Oxide scale, molding sand, etc. of precision castings are processed without margin; residues, microburrs, etc. of machined parts; oxide scale, welding slag, etc. of weldments; oxide scale, rust layer, etc. of cold and hot-rolled steel plates (section steel); Release agents, deposits, etc. for various mold cavities; sintering residues on the surface of ceramic elements; flash of plastic molded parts; radioactive elements on the surface of objects; bridges, hydropower station gates, ships, buildings; rubber adhesion layer for airport runways; Railroad car; various pipes and containers; oil stains and attachments of old parts; residual paint, rust layer and attachment of containers, etc.; Wrong sintered layers on porcelain; Scratch ....... on decorative surfaces

2. Pre-treatment of the workpiece before surface coating.

Before painting and baking; Before spraying; Before metal spraying; Before galvanizing, chromium and nickel plating; Before oxidation treatment; ...... before flaw detection

3. Change the physical and mechanical properties of the workpiece, improve or reduce the surface roughness; Variable surface tensile stress to compressive stress; Improve the lubrication state of the surface; Reduce the motion noise of the puppet parts; Increase the coefficient of friction of the surface ......

4. Finishing of the surface of the workpiece.

polishing of metal exterior surfaces; obtain matte or diffuse surfaces; Polishing ...... on the surface of wood products
