How to distinguish 3D piano paint, how to distinguish real piano paint

The piano lacquer process is a kind of lacquer process, and the process is very complex.

Mainly from the process and material to distinguish, compared with the ordinary high-gloss paint, piano paint has two essential differences.

First of all, from the process point of view:

1. Piano paint has a very thick paint layer, the furniture paint surface of real piano paint has to go through 8 to 12 piano paints, and the musical instrument we use - piano has to go through 16 processes, so as to create a piano crystal clear cold texture and long-lasting color. The surface of a real piano lacquer will shatter like an enamel if it is crushed vigorously, and will not peel off like a regular lacquer.

2. The piano paint must use special PE piano paint raw materials to be dried and cured at high temperature for many times in a high-temperature closed dust-free environment. Therefore, compared with ordinary lacquer, piano lacquer is many times higher in brightness, compactness, and especially stability. If there is no mechanical damage, the surface of the piano paint will still be as bright as new after many years, while the brightness and gloss of ordinary paint will not be comparable with new after years of oxidation and penetration.

Secondly, in terms of materials.

Piano lacquer is extremely expensive because of such a complex process. There is a very low-cost "piano paint" on the market, which is actually a "polyurethane paint spray paint" process, this paint composition belongs to the saturated type, and the piano paint belongs to the "unsaturated polyester paint", although they are very close, but this paint has not been cured at high temperature, and its own stability is less than one-fifth of the piano paint. It's hard for an inexperienced person to tell.

However, after 1-2 years, the polyurethane paint will lose its original gloss, become gray and look very old, and the piano paint will basically not change. In fact, this kind of polyurethane paint, except for 'bright', is basically not comparable with piano paint.

Piano lacquer process is a kind of baking paint process, its process is very complex, firstly, it needs to be coated with putty on the wooden board as the bottom layer of the paint; After leveling the putty, wait for the putty to dry thoroughly, polish and polish it smoothly; Then spray the primer 3-5 times repeatedly, and after each spraying, polish with water sandpaper and abrasive cloth; Finally, spray the glossy topcoat 1-3 times, and then use high temperature baking to cure the paint layer, the primer is about the thickness of the cured transparent paint, even if the temperature of the iron cup is 60-80 degrees Celsius, there will be no problem on its surface!

If it's a 3D paint, it will look like a mirror.

Bright as a mirror, delicate and smooth, resistant to high temperatures, and hard as steel – these are just a few of the features of a piano's appearance. This kind of superb holding technique used for piano was introduced by several well-known cabinet companies in China, and immediately caused a boom. Soon, almost all cabinet merchants were branded with piano paint, and it was difficult to distinguish the real from the fake on the market.

As the name suggests, piano paint is a coating specially designed for piano painting, the scientific name is polyester, which is generally composed of three components, namely basic resin, catalyst (usually cobalt) and curing agent (ketone peroxide). When these three components are mixed, a highly integrated staggered chain reaction occurs, forming a film with a certain hardness and fluidity.

In order to achieve high brightness and reasonable workability, paraffin wax and other additives need to be added to the product during production to achieve high solid content, good weather resistance and plasticity; Due to the requirements of environmental protection, the coating can only have a very low VOC content and does not contain any formaldehyde.

Piano lacquer is produced in China, Italy, Germany, Japan, South Korea and other countries. The best quality and the highest price are in Germany, but it is not easy to construct; High quality, easy construction and cheaper are Italy and South Korea.

According to the standard of the piano, the construction surface needs to be sprayed with more than 6 coats of paint, each of which is about 200 250 grams of square meters; The thickness of the paint film after spraying is up to. After the baking room accelerates drying, and then naturally parked for more than three days, and finally it is a strict sanding, polishing and waxing process. After the completion of the product paint film must be kept above 1mm, the surface is as smooth as a mirror, and the hardness is more than 4h hardness of Chinese pencil.

There is an obvious gap between the color of piano paint and the color of ordinary paint, good products are always transparent and colorless, when you need to dye red, yellow, blue, white, black and other colors, you can add a certain amount of piano paint color paste to the transparent piano paint, and you can see that the color is full of paint film with a thickness of 1mm after the product is completed. In different lighting and environments, different colors and dynamics are reflected; Translucent, with a sense of depth, different from ordinary paint, the color always floats on the surface, stiff and thin.

In addition to good equipment, the most important thing in the production of piano lacquer products is the dedication to raw materials, exquisite technical mastery and a strictly trained cooperation team. Its product characteristics are: 1. High hardness and thick paint film; Second, the mirror-like gloss and sense of depth; 3. High heat resistance (even if the metal cup is filled with boiling water and placed on it, it can be damaged); 4. Acid and alkali resistance; Fifth, the weather resistance is excellent, three or five years ago products and just baked products gloss is almost the same.

At present, the companies that can do the best piano paint are mostly cooperating with musical instrument factories, piano factories, electric guitar factories and high-end speaker factories.

Piano lacquer, as the name suggests, is the lacquer used on the piano, because the process is extremely complex, so the cost is also very high. Piano paint looks similar to ordinary spray paint and baking paint, but after a few years, the surface of ordinary spray paint and baking paint will look old or even yellow, while real piano paint will not change significantly. In fact, the real piano paint only needs to be sprayed and baked many times (3-10 times), and the paint layer is thick and hard, and there will be no traces when gently knocked or scratched.

Ordinary spray paint or baking paint is usually very thin, and the paint layer can even be torn off piece by piece after being scratched. Of course, it is impossible for us to identify through such a destructive method when purchasing, and in fact there is no need for this. Generally speaking, you can distinguish piano paint from ordinary spray paint just by visually inspecting the thickness of the paint layer.

It is mainly distinguished from the process and material.

Spray painting is mainly made of decorative panel finishing, and then spray paint with wood paint and processing. It is characterized by simplicity and practicality.

Baking paint, that is, the paint door panel that enters the drying room for heating and drying after painting. Its advantages are bright color, strong visual impact, good surface finish, easy scrubbing, moisture-proof and fireproof performance. The paint door mostly uses MDF as the base material, and the back side is triamine, which is complex and has a long processing cycle, and is relatively high. High-grade pu grilled.

There are two types of lacquer doors: piano paint and metal (automobile) paint, and metal paint is better than piano paint.

Because the quality of the paint used on the surface is difficult to distinguish, if you claim to be a high-grade PU (polyester) paint, but the ** is very low, it can be judged that high-grade environmentally friendly paint is used.

Almost impossible. When choosing a lacquered door, don't be confused by the temporary brightness of the surface, when you have ever used a low-grade lacquered door, you will find that under the pollution of oil smoke, it may change color after a long time, and the luster will gradually disappear.

The base material of the paint door is MDF, and the surface is baked at high temperature by eight spray baking imported paint (three bottoms, three sides, two lights) to form a process, that is, after painting, the paint treatment substrate door panel is heated and dried in the drying room. The characteristics of the paint board are bright color, easy to shape, have a strong visual impact, very beautiful and fashionable, and excellent waterproof performance, strong anti-fouling ability, easy to clean. The disadvantage is that the process level is high and the rejection rate is high, so the first is high; It should also be carefully cared for when used, relatively afraid of bumps and scratches, once it is damaged, it is difficult to repair, and it should be replaced as a whole; It is more suitable for young high-end consumers who have high requirements for appearance and quality, and pursue fashion.

The paint-free door is a kind of composite door, with a keel in the middle, and the two sides are glued with MDF high pressure, and the main surface layer is PVC or PU board. PVC board is lower than PU board, the price is correspondingly low, the general price is 550-750 yuan, with steel lining and non-steel lining, the difference is about 100 yuan, I said the price is even the door with the sleeve. The price of PU board is higher, and the general price is between 850-950 yuan.

If the door skin is broken, just iron it with an iron. The pass and window cover are paint-free, and the paint-free is mainly processed in the factory, which eliminates the pollution in the room, referring to the paint, which is now integrated, and the paint-free door is in line with the current trend.

Piano paint was originally mainly used in audio, musical instruments, handicrafts, bakelite to prevent the homeowner's brain, etc., and has been gradually used in cabinets since the previous year, especially in Italy and Germany and other high-end cabinets in popular areas Wang Zhu Fangzhu.

Piano paint is actually the use of unsaturated polyester resin (PE), it uses PE bottom PE surface and imported color paste, based on unsaturated polyester Ma Shi resin, its solid content is as high as about 95% of the mother beads, by polyester resin, accelerator, lead the net I build her main hair agent and paraffin liquid four components (triggering beads in the agent, accelerator, commonly known as blue, white room water), the manufacturing process is very cumbersome, the paint is a solvent-free paint, once you can get a thick coating of the net industry, good adhesion, For the acids and alkalis, wine clearing, tea and other liquids that are commonly used in the construction of her defense, it has excellent corrosion resistance.

Nobee's piano lacquer door panel is mainly produced by Italian ICA metal piano lacquer, which will not change color within five seconds of burning with a lighter, or will not change color after long-term ultraviolet irradiation; The brighter you are (see the luminosity of more than 108 degrees, the brightness of the mirror reaches 116 degrees); hardness as hard as iron (up to more than 4 5h); When curing, the cycle rate is 1 minute to build your king in the bead of the wood and other characteristics. After molding, the performance is stable, without any peculiar smell, very environmentally friendly, and has strong acid and alkali resistance and corrosion resistance. In the production process, NOBEE company adopts dust-free adsorption, dust-free ultraviolet curing technology and net construction vacuum mechanical grinding technology to ensure that the product paint film is plump and smooth, high transparency, excellent wear resistance and hardness, non-flammable, anti-yellowing, can be washed and soaped.

In fact, most of the steel and pearl paint in the market is PE bottom PU surface, PE bottom PU surface has a high degree of fullness, good anti-sag performance, but the yellowing, hardness, luminosity and acid resistance of my soil are worse than PE bottom PE surface, so this product wood and soil anti-I am not really piano paint beads beads, its circulation has seriously affected the promotion of steel and soil she piano paint as a high-end city bead in his real estate industry.
