What are senior wooden furniture surface coating processing method and means

advanced wooden furniture white embryo must brush thin shellac varnish; Should put sanding, stare blankly, carefully to grinding through; Between the coating to brush color bright color; Repeated inlaying putty to ensure that the coating surface is flat and level. The thickness of the film must be guaranteed; Film flatness is higher; Finishing all polished. Besides the above coating requirements, sometimes even wipe shellac varnish coating, coating of peel color in order to assure the uniformity of coating color and clarity; Using simulated wood grain texture material to make ordinary rare wood texture; Sometimes certain indicators should accordingly improve physical and chemical properties of paint film, etc. , in order to achieve high-level coating quality.

in addition to the above coating requirements, sometimes even wipe shellac varnish coating, coating of peel color in order to assure the uniformity of coating color and clarity; 3, sanding: 1 wood with sandpaper grinding edges and stare blankly, suitable wood grain carefully polished surface coating, sand to wood wool, sand flat to be bored with child. Brush with wool combination brush pen or pig hair brush by hand.

a white embryo, senior custom furniture must meet the following prerequisites:

1, wood drying, processing fine;

2, wood has a beautiful natural texture;

3, according to the film quality requirements and reasonable to make painting process, selection of high quality coatings, with skilled technology and strict with every procedure of the operation.

4, beautiful modelling structure unique, fast;

coating pretreatment is not only the foundation of the coating, and coating the indispensable important component, is the key to improve coating adhesion and corrosion resistance. Before processing quality of high and low, directly related to the merits of the coating quality, the length of the coating product life and the size of the market competitiveness, and even related to the value of coating products. Must be a link in the process of full attention.

example: now with pine furniture surface treatment before finishing for example:

surface conditioning: 1 wood with sandpaper smooth surface, purify bilge oily be soiled. Primer: in acrylic resin addition amount of diluent, matt varnish smooth hind to brush or spray, under the condition of 20 DHS C dry about 2 hours. Inlaying: with shellac old powder putty inlaying hole, crack and surface depressions. Embedded putty to fill. Inferior smooth varnish coating paint, acrylic resin, 100, 120 dedicated diluents diluted, brush or spray on the surface of the furniture. Polishing: 1 wood with sandpaper will be bored with child after drying of smooth. Rag wipe wood dust. Finish: 0 wood with sandpaper grinding smooth gently.

1, remove resin: soft wood parts with resin, will also affect the uniformity of film adhesion, and color. Can be used commonly 5% ~ 6% sodium carbonate solution or 4% ~ 5% caustic soda solution cleaning, make rosin saponification, then with the brush or sponge reef hot water is swabbed clean. Available knife, cut it, and again on the same wood, wood fiber direction should be consistent. Also can use alkaline cleaning first, and then washed with water. If it is not allowed to dig available organic solvent wash, commonly used solvents have turpentine oil, gasoline, toluene, acetone, etc. After removing resin, surface drying, brush 1 ~ 2 way shellac varnish through the region, to prevent internal seeping resin again.

2, remove wood wool: furniture made of wood, although its surface after plane or polished, bright and clean degree meet the requirements, but there are always some not completely out of the wood fiber on surface of wood surface. Once these wooden fiber absorb water or solvent, will stand up for wet expansion. Because there are a wood wool, wood surface coating color will product set around it, and affect the uniformity of color. At the same time, wood wool inside with color, not when the sand to wood wool, wood wool break and reveal itself color, coating can appear white dots, commonly known as the white sesame seeds. Must go before finishing wood wool, general furniture upon several sanding, senior furniture can use the following methods:

3, remove dirt, paint on the surface of the stain ( Such as glue mark, oil, etc. ) , it will affect the uniformity of coating color and paint dry and film adhesion, so to clean up before finishing. The surface of the dirty can use 1 or 1 and a half of sand. Sand should be used when not to drop off a short plane will surface clean. Scrape the tenon joint traces of paint and other agglutination. Oil stains can use sand first, and then wash with gasoline, or use the fire burn method processing.

4, fill and inlaying, often have some hole on white body furniture, such as worms, nailhole, timber desiccation crack, inverse grain cutting form when reverse grain grooves, tree next to the section of local pits, and broadleaf timber catheter slots, etc. So you must according to the specific situation, old pink, with be bored with child, water oil old powder filler sew the hole fill level. The seam hole absorb general varnish, paint coating, such as waste paint and coating surface is uneven, affect the quality of coating. Be bored with child by paint workers generally own deployment of use at any time in the construction site. Putty is not only used for larger hole seam inlaying, also used for finishing the full bridge. Putty is to use a large amount of extender pigment ( The commonly used old powder, gypsum, etc. ) , varnish or paint, color pigment and just the right amount of water and solvent deployment and become.
