Coating general knowledge: classification and characteristics of waterborne wood paint coating process

Core tip: people usually focus on the coating products themselves when decorating, and they require famous brands to ensure environmental protection and health, but they often ignore the importance of construction In fact, the coating is only a semi-finished product, and only after standardized construction and application can it become a coating, so as to achieve the final decoration and protection effect As the saying goes, "three paint, seven construction", all these show the importance of coating process to coating quality As a new coating product, water-based wood paint is compared with the original solvent based paint in construction application Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: people usually focus on the paint products themselves when decorating, and require famous brands to ensure environmental protection and health, but often ignore the importance of construction In fact, paint is only a semi-finished product, only after standardized construction and application can it become a product, achieving the final decoration and protection effect As the saying goes, "three paint, seven construction", all these show the importance of coating process to coating quality As a new paint product, water-based wood paint has great convenience and freedom compared with the original solvent based wood paint in construction application However, if you want to achieve good decoration effect, you must be familiar with the painting process of water-based wood paint At present, the coating process of waterborne wood paint is usually classified and characterized as follows: (1) classified according to the transparency of coating 1 Transparent coating It refers to completely using transparent water-based wood paint (such as transparent water-based wood varnish, transparent water-based colorant, etc.) to coat wood products and form transparent film on its surface The feature of this coating process is to retain and show the real texture of the base material, which is mostly used for the coating of solid wood products or planed veneered wood-based panel products; 2 Opaque coating opaque coating is using pigments The opaque water-based wood color paint (water-based solid color wood paint) is used to coat wood products, which is characterized by the formation of opaque color or black-and-white film, covering the surface of the coated base material, and is mostly used for the solid wood products with poor texture or the wood-based panel (particleboard, MDF) products without veneering; (2) classification by film luster 1 High (bright) light decoration It is painted with high (bright) water-based wood finish, generally with 90 degree gloss, which can make the paint film reach enough thickness to make a bright "mirror effect" The paint film is full, thick, elegant, light-sensitive, and presents high gloss; 2 Matte decoration Different Matt water-based wood paint can be used to make different gloss (full dumb, semi dumb) Matt effect coating The matt film has a soft and elegant, simple and beautiful, natural and quiet low gloss decorative effect Due to the fact that most of the finishes of matte water-based wood paint are thin coating, compared with high (bright) light decoration, it can simplify the coating engineering, save labor and materials, and partly cover up some disadvantages of poor substrate and coating technology But it should be said that high (bright) light and matte decoration have their own characteristics and styles （3） According to the classification of whether to fill holes or not 1 Hole filling decoration (full sealing) is to use special water-based wood putty and water-based nail paste to fill the holes of wood pipes completely and firmly, or to use water-based sealing primer for sealing The fully closed water-based coating can achieve the effect of high gloss and thick coating, full and thick paint film, and smooth surface; 2 The hole display decoration (fully open) is not filled with holes, and the water-based sealing primer is not applied, most of which are thin coating coating coating, so as to fully expose the wood pipe holes and show the effect of natural texture of wood; (4) classification according to transparent coloring operation 1 Painting process of intermediate finishing of bottom coloring It refers to the coloring of water-based colorant directly on the surface of wood Depending on the coloring effect, transparent primer and transparent finish can be applied, or transparent varnish can be applied in the coating (between the bottom and finish coats) after the color is repaired and supplemented by water-based colorant The characteristics of this coating process are good coloring effect, uniform color, clear layers and clear wood grain; 2 The surface coloring coating process refers to the use of water-based transparent color paint to paint the finish at the same time Compared with the above process, it is simpler, and there is no worry about the ground color, but the wood grain clarity may be affected （5） According to the classification of whether the surface paint film is polished or not 1 The water-based wood paint can also be used for polishing coating process, which is to use 1000 × sandpaper to fine grind the whole paint layer (including the primer and finish paint film), and then use polishing paste or wax liquid to rub and polish The surface paint film can be rubbed smooth and throw out luster, which can eliminate almost any coating defects After polishing, the paint layer is glossy, gentle, bright and even, which can reach the mirror effect; however, when using polishing coating process, it must be noted that the whole paint layer must be dry; in addition, after polishing and waxing, it can not be repaired If repairs are to be made, the wax layer must be sanded off 2 The original light decoration process refers to that the wood has been completely coated (including the last finishing coat) and then it has been completed after being dried The surface of the paint film will not be polished, which simplifies the construction process, improves the efficiency and shortens the construction period In the past, the painting quality was not as good as the polishing decoration when the painting conditions were poor With the improvement of the painting conditions, the original light decoration can also achieve high decoration quality Moreover, the original light painting with water-based wood paint can be repaired at will It is a popular painting method at present Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
