What are the effects of long term application of paint and thinner?

The impact is many! Let's talk about the biggest impact! The main harmful substance in paint is stupid, which chronically affects the brain's ability to react! Brain atrophy.

Summary. The high concentration in the high-concentration varnish refers to the relatively high net content of solid resin in this paint, which is commonly found in acrylic varnish (solid methyl methyl methacrylate content), nitrovarnish (solid nitrocellulose ethyl cellulose content) and alkyd varnish (solid alkyd resin content), these varnishes are one-component, and their film-forming mechanism is very simple after solvent volatilization. This indicator is not commonly found in polyester, PU and epoxy because they are liquid monomers that require a hardener to initiate cross-linking, so there is no such thing as concentration.

Generally speaking, we think of high concentration as a viscous liquid with a solid content of at least 30% or more, which needs to be diluted before it can be sprayed into a film.

What is the effect of putting more thinner and less thinner during paint construction?

Hello, I am the answerer Yu Xin, I have seen your question, wait a minute, here will be sorted out the answer for you to answer

During paint construction, the thinner will eventually volatilize if the thinner is put more and less ridged, so there are many people who can use the thinner or not, in fact, Hangzhou Yasheng paint reminds that the thinner is indispensable for paint construction, and putting more and less is causing problems with the paint film. Too much, the paint will sag, not dry for a long time and other problems, too little, there will be too high paint concentration, uneven paint film, uneven cherry socks, uneven surface and other problems. Therefore, it is necessary to find a professional builder or professional painter to know about it during construction.

What does it mean that the paint concentration is too high?

The high concentration in the high-concentration varnish refers to the relatively high net content of solid resin in this paint, which is commonly found in acrylic varnish (solid methyl methyl methacrylate butyl ester content), nitro varnish (solid nitrocellulose ethyl cellulose content) and Zhipai alkyd varnish (solid alkyd resin content), these varnishes are one-component, and their film-forming mechanism is very simple solvent volatilization after film-formation. This indicator is not commonly found in polyester, PU and epoxy because they are liquid monomers that require a hardener to initiate cross-linking, so there is no such thing as concentration. Generally speaking, the high concentration of Changmeng Song is a viscous liquid with a solid content of at least 30% or more, which needs to be diluted before it can be sprayed into a film.

The thinner is chemical, as long as it is chemical, no matter what it is, it is not good for the body, try not to get paint on the body, wear a gas mask, do not use thinner to clean the place where the cloth thinner gently rubs the paint, probably like this, I am a paint technician myself

Harmful, especially containing benzene, ester organic solvents, bad smell, and these are carcinogens, it is best to wear a gas mask with activated carbon, get it to the body in time with clean water, if the redness and burning feeling is strong, to seek medical attention in time.

If you feel hot, it should be an oil-based solvent, which is more harmful than water-based solvents, and it can't be washed off with water alone, so you should wash it twice with soap.

That's for sure, masks must be worn while operating.

Hello, the paint thinner used in the past is highly toxic. Inside the paint thinner, toluene and xylene are added, which are toxic, and if the human body inhales this gas for a long time, it will be poisoned. Therefore, when using paint thinner, it is necessary to wear masks and gloves, and make the construction site ventilated.

With the continuous progress of science and technology, the developed paint thinner does not contain toluene and xylene, so the toxicity will be relatively low, and even some products are directly non-toxic, and the safety performance of later use is also higher. In addition, the paint thinner also has the ability to remove oil stains, which can clean the oil stains on the surface of the part and increase the bonding performance.

It is best not to touch it, and if you really do not pay attention to physical contact, rinse with water, which can effectively relieve pain. Hope it helps.

My hand hurt the thinner for five or six days.

Try not to make direct contact**. Wear protective gear. There won't be major problems. Vary. Use some anti-inflammatory drugs.

It is said that the return to the motherland will be strong and unloaded.

When the paint is used, it cannot be used directly, and thinner is required.

The paint is too dense and does not dry easily, and the thinner is a volatile liquid used to dissolve and dilute the paint. It can be used to adjust the viscosity of the coating to suit the coating requirements.

Only the solvents used in some coating products (such as nitro paints) need to be added with co-solvents. Although the diluent cannot dissolve the film-forming substance, it can be used with the solvent of the coating without causing harmful effects, and the application of the dilutant is mainly to adjust the volatilization rate of the diluent and reduce its cost.

1. To join.

thinner, otherwise the paint cannot be disassembled, sprayed and so on.

2. The dilution of paint is generally in the proportion of 15%-30%, of course, the concentration of different manufacturers is also slightly different. Then you have to adjust while observing, slowly add water or thinner while stirring inside, dip it in paint with a relatively clean wooden stick, and lift it to see about 10-20cm away from the barrel. A downward flow that does not form a line proves to be too thick.

Just take care of the portion yourself.

If you want a diluent, there is a ratio of the column.

Painting: Applying paint to the surface of an object with a manual brush is called painting. Its characteristics are:

Paint saving, simple tools, easy to apply, easy to master, flexible. The disadvantages are: high labor intensity and low productivity.

The applicability of the quick-drying paint is poor, and if the operation is not skillful, the paint film is prone to defects such as cracks, sagging and unevenness.

Before painting, the paint must be stirred evenly (in case of pigment precipitation during the storage period), and adjusted to the appropriate viscosity, generally judged by experience: that is, after the paint is lifted with a brush, 30 50 drops per minute hand naturally flow are appropriate. Less staining and more brushing, from top to bottom, from left to right, first inside and then outside, first oblique and then straight, first difficult and then easy, vertical and horizontal brushing.

It should also be noted that the vertical surface should be carried out from top to bottom; For horizontal surfaces, it should be carried out in the direction of light.

The paint will be too dense when used directly, and it is not easy to cool dry. It is recommended that you add Tina water, which is about 500kg of paint to 150kg of water. If you don't want to use all the paint at once, you can also pour out the amount you expect to use and let it be diluted with the appropriate proportion of Tianna water.

Be sure to use thinner, how to use it dry.

Paint thinners contain toluene and xylene, which can adversely affect the body's hematopoietic system. Long-term exposure to paint thinners can cause leukopenia and thrombocytopenia (which kills white blood cells), which may lead to aplastic anemia, also known as leukemia. In severe cases, it may also affect the nervous system, causing neurological disorders.

At present, the pure benzene contained in the environmental protection paint thinner has begun to slowly decrease, and most of them are substitutes such as benzene and xylene with skin punching, and the concentration is lower than the national standard. If it is not for long-term exposure to paint thinners and the workplace is well ventilated, the incidence rate is not high. But if you are exposed to paint in a closed environment for a long time, of course, it is not good.

Diluent is a liquid substance that is well miscible with resin added in order to reduce the viscosity of resin and improve its process performance. There are reactive and inactive diluents, respectively. In paint and coatings, diluents need to be added to reduce its viscosity and facilitate further processing, and these diluents are actually organic solvents that are cheaper than resins, so they also play a role in reducing processing costs.

The unique degreasing function of paint thinner. To remove the oil stain before painting, you can soak the machined parts in the solution to clean the oil stain and increase the adhesion force.
