How to spray woodworking paintIs woodworking spray paint harmful to the body?

You asked about how to spray woodworking paint, I want to answer it in two points. One is the varnish construction process, and the other is the mixed color paint construction process. Because I am not a carpenter, I just found the process of these two processes in the professional **, you see if it will help you (1) Varnish construction process:

Clean the surface of the wood Finish with sandpaper Finish on the powder Sandpaper Scrape the first putty, sandpaper polish Scrape the putty for the second time, polish the fine sandpaper Brush the oil Brush the first varnish Spell the color, refill the putty, polish the fine sandpaper Brush the second varnish, fine sandpaper polish Brush the third varnish, polish the water sandpaper sandpaper, wax, polish. (2) Mixed color paint construction process: First sweep the dust on the surface of the base layer, repair the base layer, flatten it with frosted paper, paint the piece at the scar, scrape the putty at the base, apply dry oil, scrape the putty for the first time, polish it, paint the bottom coat, dry and hard the bottom coat, paint the surface layer, repair the putty, polish and wipe the third topcoat, paint the second coat, polish the third topcoat, polish and wax.

Hazards of spray painting: In the case of painting without protection, the concentration of benzene in the air in the workplace is quite high, which is extremely harmful to painting workers. Long-term exposure to benzene can cause chronic poisoning, resulting in leukopenia, thrombocytopenia, bone marrow hematopoietic dysfunction and other diseases.

The harm of paint to the human body can occur not only through inhalation in the lungs, but also through absorption. The human body is in direct contact with the paint, which can dissolve the fat in the paint, causing cracks and inflammation to enter the human body. Woodworking spray paint is definitely harmful to the human body, but now carpentry generally has protective measures during construction, so the damage to the human body will be reduced.

It's not easy to do in all walks of life, and we have to be more considerate of the hard work of these painters.

Formaldehyde harmful gases are seriously exceeded.

1. Remove any metal hardware. If you also want to paint metal hardware, paint it separately from the wood to ensure full paint coverage.

2. Remove the varnish or polishing agent. Use an electric sander or sandpaper to wipe off the glossy outer coating of the wood as much as possible.

3. Wipe off the sawdust with a dry cloth. Avoid using a damp cloth so you don't have to wait for the wood to dry before painting.

4. Apply primer. There is a special primer for wood bending on the market, but you only need to spray it with a normal primer.

5. Spray paint towards the wood. Spray an even layer of lacquer and spray the surface of the wood at a distance of 20 cm from the cavity. If you want to spray multiple coats of paint, you must wait for the coat to air dry before each spray.

Woodworking paint is a kind of paint, that is, the paint on the furniture we make is called woodworking paint, and the types of paint can also be divided into two kinds, one is wall paint, and the other is woodworking paint, so how to spray woodworking paint, what are the types of woodworking paint spraying? Here are two recommended ones to take a look at?

The relevant knowledge of woodworking paint practice is introduced here, the above two practices are recommended, which can be selected according to the needs of the home, here is a reminder: wood paint should be brushed after the completion of ground construction, and ventilation should be maintained during construction, without dust, so as not to affect the overall effect, wood paint and latex paint can not be constructed at the same time.

1. Generally speaking, the toxicity of amino groups is greater.

It seems that some of them also contain cyano groups.

The most important thing in the painting process is the damage of benzene to the human body.

Over time, it will generally cause lung and ** diseases.

According to individual resistance.

Some also have sexual dysfunction.

2. In fact, pay attention to spraying environment purification and self-protection [buy regular gas masks on the market.] Clean and replace activated carbon according to regulations].

Do not exceed 7-8 years.

Ordinary people are fine.

The main methods of prevention are:

1. Before painting construction, the doors and windows should be opened, and the screen windows and screen doors with nylon silk should be installed on the door and window frames. Turn on the exhaust ventilation equipment to allow the air to flow smoothly and accelerate the dispersion of paint mist and gases.

2. When spraying paint, you should wear work clothes, gloves and masks to prevent paint mist and gas from touching the human body or inhaling into the mouth.

3. Take a shower after painting. On ** directly affected by lacquer mist and gases, petroleum jelly, oil or emollient ointment can be applied without drying out or cracking.

4. If you feel headache, dizziness, palpitations or nausea when working in the paint spray room, you should leave the work place immediately and rest in a place with fresh air, and if you are serious, you should go to the hospital**.
