Mahogany furniture paint more beautiful
After the mahogany furniture is painted, the entire furniture looks very full and shiny, in line with the aesthetic eyes of the public. In addition, after the mahogany furniture is painted, it plays a protective role for the furniture. In the south, due to the relatively humid climate, many surfaces of furniture are basically covered with a thin layer of lacquer to prevent moisture. For example, mahogany furniture made in Suzhou is characterized by a layer of varnish both inside and outside, which protects the mahogany furniture inside and out. In addition to Suzhou, mahogany furniture made in Guangdong is also rubbed with a layer of lacquer, so mahogany furniture made in Guangdong is not only luxurious, but also has a very soft color and is not easy to spoil.
Unpainted mahogany furniture is more natural and environmentally friendly
Due to the natural and environmentally friendly nature of wood, some consumers prefer to purchase unpainted mahogany furniture. Because the unpainted mahogany furniture emits aroma of wood with changes in time and climate, especially the rare woods of lobular rosewood and huanghuali. The grapefruit garden furniture has learned that the aroma of wood emitted from it is very Good, with a certain health care function.
It is also known that the climate in the north is relatively dry, and many mahogany furniture are not painted at the time of production. Only a layer of wax is applied on the surface of the furniture. This mahogany furniture after hot waxing has undergone long-term repeated frictions in the course of its future use. The wax on the surface will infiltrate into the wood and become oxidized to generate pulp. The surface of the furniture that has formed a pulp slurry cannot be heated by boiling water, nor can it stick to highly soluble liquids such as gasoline, otherwise it will damage the pulp slurry.
Types of mahogany furniture paint
(1) Nitro varnish. Nitro varnish is a kind of transparent paint made of nitrocellulose, alkyd resin, plasticizer and organic solvent. It is a kind of volatile paint, with quick drying and soft gloss. Nitro varnish is divided into light, semi-matt and matte, which can be selected according to the need. Nitro-lacquer also has its disadvantages: high wet weather is easy to whiten, low fullness, and low hardness.
(2) Hand sweep paint. Nitro lacquer is also a nitrocellulose paint. It is a non-transparent paint made of nitrocellulose, various synthetic resins, pigments and organic solvents. This paint is specially formulated for artificial construction and has a quick drying feature.
(3) The main auxiliaries for lacquer: a. It is a colorless, transparent liquid with a banana odor that is made by mixing organic solvents such as esters, alcohols, benzene, and ketones. It mainly initiates the lacquer and curing of nitrocellulose. b. White water. Also known as anti-white water, the scientific name is ethylene glycol monobutyl ether. In the wet weather construction, the film will have a whitening phenomenon. Adding 10%-15% of the diluent to the nitromagnetized white water can be eliminated.
(4) Polyester paint. It is a thick paint made of polyester resin as the main film forming material. The paint film of polyester paint is full and the layer is hard. Polyester paints also have varnish varieties called polyester varnish. Polyester paints need to be cured during the construction process. The amount of these curing agents accounts for one-third of the total paint content. These hardeners are also called hardeners and their main component is TDI (toluene diisocyanate). These TDIs that are in a free state will turn yellow, which will not only make changes to the furniture, but will also cause yellowing of adjacent walls. This is a major drawback of polyester paints. A yellowing-resistant polyester paint has appeared on the market at present, but it can only achieve "yellowing resistance." It cannot yet be completely prevented. In addition, free TDI beyond the standard can also cause harm to humans.
(5) Polyurethane paint. Polyurethane paint is polyurethane paint. Its film is tough, full gloss, strong adhesion, water resistance, wear resistance, corrosion resistance, is widely used in advanced wood furniture, but also for the metal surface. The main disadvantages are the blistering of the tide and the chalkiness of the paint film; as with the polyester paint, there is also a problem of yellowing. The varnish type of polyurethane paint is called polyurethane varnish.
(5) The lacquer is a kind of high-quality paint, which has the reputation of “national paint†because the raw paint is not only healthy and environmentally friendly, but also has strong adhesion, acid and alkali resistance and corrosion resistance to the lacquer, and has a long-term protective effect on the mahogany furniture. And the decorative effect is very good, which greatly prolongs the life of mahogany furniture, enhances the appreciation space of mahogany furniture, and enhances the value of art appreciation.
