Furniture painting refers to the paint coating suitable for furniture. Its painting features mainly reflect retro and return to nature, fully showing the true color of wood. As it caters to the psychological needs of mankind yearning for nature and returning to nature, it is a trend in the future development of furniture. A major feature of furniture spray production is standardized production, its production process is relatively stable, and production technology is relatively mature. Most of these enterprises are Taiwan-funded enterprises, and a small number of them are Hong Kong-funded enterprises. Most of their products are sold by large multinational trading companies, such as IKEA in Sweden and Yali in the United States.
Furniture painting process
The furniture painting process mainly includes the process of substrate damage treatment, material processing, overall coloring, filler, primer, absorbing, coloring, color retouching, secondary primer, topcoat, polishing and waxing. A brief introduction will be made below.
1. Substrate destruction: Destruction is a processing process with a strong antique effect in the process of painting furniture. It mainly mimics the traces of wind erosion, insect frogs, damage and vandalism. Its role is to enhance the antique effect of the product, to cover up the defects of the product, to improve the value of the product, the main damage of the substrate is as follows:
Wormholes - wormholes are traces of wood after being wormed and insects after long-term storage. In general, the phenomenon of insects is more common in the destruction of the product and the edge of the product. The place where there is a knot and the center of the wood are relatively hard, and the insects generally do not reach these places. The insect frog has some scattered places. There are also intensive agglomerations.
Sickle marks - Sickle marks are traces of the imitation of a product that has been zigzag-shaped during long-term use or storage.
Horsetail, scars - horsetail marks, also known as scratches, are traces of scratches and scratches of imitation products during use; scars are imitation products that are wormed after long-term use or storage, and left after the insects have climbed Mark of.
Hammer marks - Hammer marks are traces left after being hammered at a certain angle with a hammer. It is mainly a trace of a product that has been crushed or damaged by other objects during long-term use. Spray point (also known as "fly black spot") - the point is mostly black, dark brown, is a transparent or opaque coloring paint, commonly known as "fly black spots." It is mainly a process in which the excrement left by the flies on the product during the long-term use or the traces left by some colored objects splashing on the product is a process with strong antique effect.
Cloth printing - printing, also known as angiography, is a process often used in the painting process of furniture. Its main function is to enhance the layering of the product and deepen the color of the product. It is processed at the level of reducing the color of the product as described below. Combined, the product is presented in a light, medium and deep color hierarchy.
2, material processing: due to the wood itself, the color difference, can be mixed with dyes or pigments in the solvent, and then adjust the color of the material, the material can be adjusted with bleach and color modifier.
3, the overall coloring: also known as the background coloring or material coloring, is to paint the background color of the material to approach the color of the swatch, generally using spray operation. The colored materials mainly include: alcoholic colorants, lint-free colorants, penetrating pigment colorants, oily colorants, and dye colorants.
4. Filling agent: Adding pigment to the wood silk filler to fill the pipe and increase the grain texture of the wood, and achieve both filling and coloring functions. When filling, attention must be paid to the adhesion. If the adhesion is not good, the coating film will peel off easily after coating; if the coloring is not good, the color is not uniform, the wood texture is not clear; if the filling is done well, the primer can be saved. The number of sprays with the topcoat makes the mirror finish better.
5, the first primer: solids are usually between 4-14%, because of the low viscosity, it will soon penetrate into the surface layer of wood, providing a "continuation" effect in the coating process.
6. Toner: It is prepared by adding dye or pigment to the primer. The solid content is between 2-10%. Generally, after the coloring or filling operation of the material is completed, it is used to deepen the color. Its function and head. It is the same as the primer, but it can also be used directly in the material to replace the material coloring and the glue primer. Because the colorant does not penetrate into the wood, it is easy to cause white marks due to scratches, and special attention must be paid. It is mainly used in places where the coating line is short, and it is difficult to separately use the material to color and glue the primer over the primer. The effect is better on the large plane. It can be sprayed on the surface and evenly colored, but in the chair and bowl. It is more difficult to spray evenly on the inside of the disc cabinet and on the styling fittings, so the color control is more difficult and generally less used.
7, Grace's transparent main Jing: In order to prevent the end surface texture from becoming deeper, in general, it should be closed with Grace's transparent main agent before using the colorant. Apply it to the end face texture with a fine cloth or brush when using it, which can block the end face tube and wipe it clean to make the color uniform.
8, Grice coloring agent: also known as antique lacquer, is made in a slow-drying and easy to wipe oil or resin, the translucent or transparent pigment dissolved in oily solvent. Its purpose is to use its translucency to reduce the brightness, soften the surface, create contrast and shadow effects, and create a classic interest.
9. Second-degree primer: The second-degree primer is used to protect the base colorant and the Grice colorant, and increase the thickness of the film and smooth the surface. It is characterized by adhesion, filling, sanding, transparency, and drying, and acts as a "bridge" with the topcoat.
10, color correction: This is the last coloring process in the entire painting process, this process must be compared to the standard color plate for color correction, color correction can be fully sprayed, can also be local enhanced color correction according to the actual situation; Sex coloring agent color correction, after finishing the color, you can also use cloth or steel wool for local repair work.
11. Topcoat: The topcoat is the final step in the coating process and is the most intuitive appearance of the product, so the fullness and transparency of the film is very important.
12. Polishing and waxing: In order to make the coating surface smoother, increase the feel of the coating film and enhance the aesthetic appearance of the coating film, it must be polished and waxed. First use a straight sanding machine, use 800#-1000# water sandpaper to rub the lubricant or loose perfume to smooth the coarse particles on the surface, and then use the high-speed polishing machine wool wheel to polish the surface to the required speed at 2000rpm. The brightness is finally wiped clean with a clean soft cloth.
Slicer and dicer(meat dicer) are used in different fields of food industrial such as for meat, cheese, vegetables, fruits etc. Helper`s slicer and dicer seies are applied in both restaurant and industrial plant. To produce portioned bacon, the Rib chopper will help. To make vegatable and meat mixture for dumpling production, QD02 vegetable dicer will be the best choice.
In addition to them,we also supply the cubing machines.
