What is paint?

Gourmet paint, also known as paint, can also be collectively referred to as paint coating, which is a very common decoration consumables. Paint and coating can firmly cover the surface of objects, and the use of paint and coating can play a protective and decorative role in decoration. When buying paint, we need to pay attention to environmental protection first, and then consider the details such as color, luster and fineness of paint. The paint you buy home can be applied by yourself or by a painter. After the construction, we need to deodorize and clean the paint so as not to endanger human health. Let's take a look at it with editor Maigoo.

What is the composition of the paint? Coatings are generally composed of film-forming substances, fillers (pigments and fillers), solvents and additives. According to the performance requirements, sometimes the composition will change slightly, such as varnish without pigments and fillers and powder coating without solvents.

Paints and coatings are classified according to coating forms: liquid coatings (solution type, emulsion type, dispersion type, solvent-free type), solid coatings (powder coatings) and so on.

According to pigment content: varnish, colored paint, etc.

According to the film-forming process: primer, putty, intermediate paint (intermediate coating), topcoat, topcoat, etc.

According to the use of coatings: architectural coatings, industrial coatings, general coatings and special coatings. Industrial coatings include wood coatings, automobile coatings, ship coatings and light industrial coatings.

According to the film-forming substances: phenolic coatings, alkyd coatings, nitro coatings, polyurethane coatings, epoxy coatings and so on.

According to the coating function, it is divided into antirust coating, anticorrosive coating, temperature-resistant coating, fireproof coating, insulating coatings, antifouling coating, etc.

According to the film forming mechanism, it is divided into volatile drying coating, hot melt drying coating, air drying coating, drying coating, multi-component curing coating and radiation curing coating.

According to the construction method: brushing, dip coating, electrophoretic paint, self-swimming paint, etc.

The difference between paint and paint Now, paint and paint are actually the same thing. In the early days of paint, vegetable oil was the main raw material, so it was called "paint"; Coatings contain more scientific and technological components and are widely used in modern science and technology and industrial fields. It can be said that the paint contains paint. But it still retains some customary names of coatings, such as latex paint, primer and topcoat.

Are paints and coatings harmful? Paints and coatings are dangerous because their ingredients contain some harmful substances, such as formaldehyde and toluene. Moreover, paints and coatings are flammable and explosive, and there are great security risks in the process of production and use, so they are listed in the environmental management registration of hazardous chemicals by the state. What kind of dangerous goods does paint belong to? Paint belongs to the third kind of flammable liquid in dangerous goods.

How much is the paint per square meter? Different kinds and brands of paints have different prices. For example, the interior wall paint commonly used in home improvement is generally about 20-20 square meters in 40 yuan, while the price in exterior wall paint is a little more expensive, because the performance requirements in exterior wall paint are higher.

Paint and coating selection points 1, environmental protection

The environmental protection technical indicators of paints and coatings include VOC content, formaldehyde content and heavy metal content. When reading the test report of the product, we should also pay attention to whether its odor purification technology, bamboo charcoal adsorption and other properties meet the standards.

Step 2 be elegant

The fineness of paint refers to the size or dispersion uniformity of pigments, bulk pigments and other particles in paint or paste, expressed in microns. The fineness of paint will affect the physical and mechanical properties of paint film, such as luster and water permeability. Generally speaking, the finer the paint, the more expensive it is.

3. Notes

The gloss of paint is a physical property, that is, the ability of paint surface to reflect the light incident on it. The more reflected light, the higher its luster. The higher the gloss, the stronger the reflection, so many consumers are more inclined to buy matte coatings.

Step 4 color

When choosing the color of paint, we should comprehensively consider the requirements of function and beauty, as well as the characteristics of space form and decorative materials. Mai Guzhuang trims Xiao thinks that the living room should choose bright and lively colors; The color of the bedroom is preferably warm and softer; The study should focus on elegance, solemnity and harmony.

Paint quality appraisal 1, look.

Be sure to go to a regular building materials market or a specialty store to buy it, and check the relevant test report of the product, whether there is a "ten ring" logo, and whether the information on the package is complete and true. Look at the sample of wall paint. Good wall paint is generally transparent and shiny.

Step 2 smell

Environmental protection wall paint has elegant and pure smell. You can ask to open the lid of the paint can and smell the sample paint to judge the smell.

Step 3 touch

Touch the paint film by hand. Good wall paint has high solid content, delicate and smooth feel, and inferior paint will have obvious graininess.

Step 4 row

Scratch the paint film with hard objects such as toothpicks or nails. Good wall paint has high hardness, good scratch resistance and is not easy to scratch, while low hardness wall paint will have obvious small scratches, which will affect the beauty of the wall.

1, the misunderstanding of choosing paints and coatings, paying attention to price and lighting quality.

Some people think that the higher the paint price, the better, so they choose the most expensive one, but this is not the case. Although some brands of paint are expensive, the quality is really not up to standard. I suggest that you try to choose a brand with good reputation when choosing.

2, tasteless and environmentally friendly

Because odorlessness can be achieved by adding essence or using low-odor materials, it is not simply judged by odorlessness, but depends on whether the key environmental indicators (VOC, free formaldehyde, heavy metals) of wall paint are qualified.

3, the pursuit of scrub resistance

According to national standards, the washing resistance of qualified coatings is not less than 300 times, while the washing resistance of some coatings has reached tens of thousands of times. The scrub resistance of the coating is good, but the cost should be increased accordingly, and consumers don't have to paint the wall so much. Select the appropriate number of times of scrubbing resistance.
