Paint knowledge - basic knowledge of wood paint construction

Core tip: there are three effects of wood painting: closed, semi closed and open The closed effect is to completely cover the wood grain, while the open effect is to show the natural wood texture According to the different effects, the construction methods of wood paint are different In addition, there are mainly three kinds of wood paint: nitrocellulose paint, polyurethane paint and water-based wood paint Due to the different components of the products, the construction methods are also different There are various construction methods of wood paint It is best to choose the appropriate construction method according to the desired painting effect and the selected products In fact, there is little difference between various construction methods, which may be the difference of sequence and painting times 1 Plate Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: wood painting has three effects: closed, semi closed and open The closed effect is to completely cover the wood grain, while the open effect is to show the natural wood texture According to the different effects, the construction methods of wood paint are different In addition, there are mainly three kinds of wood paint: nitrocellulose paint, polyurethane paint and water-based wood paint Due to the different components of the products, the construction methods are also different There are various construction methods of wood paint It is best to choose the appropriate construction method according to the desired painting effect and the selected products In fact, there is little difference between various construction methods, which may be the difference of sequence and painting times 1 Before the treatment and painting of the board, the wood shall be cleaned first, and the dust on the wood surface shall be wiped clean When cleaning, special dust cloth can be used For large areas, such as floor, dust can be repeatedly vacuumed with a vacuum cleaner At the same time, polish the board surface or wood line surface with sandpaper, pay attention to protect the wood skin, not sand through The purpose of plate treatment is to effectively remove the stains, wood wool and wood thorn on the plate, so that the surface of the plate is clean and smooth, so that the subsequent painting can save labor and material 2 Plate sealing can effectively seal the plate and prevent the plate from being polluted Plate sealing can prevent excessive moisture absorption, moisture dissipation and deformation of the plate, enhance the adhesion between the paint film and the plate, save paint consumption and enhance the hardness of the paint film 3 The matching wood putty shall be selected for puttying, and after mixing, the putty shall be fully piled up to the wooden hole After the putty is dry, sandpaper shall be used to polish and thoroughly clean the putty on the wooden tools Filling wooden holes with putty can reduce the amount of wood paint and improve the smoothness of paint film Different painting effects have different requirements for putty scraping and coating For example, to make an open effect, the putty color should be modulated to be consistent with the plate color before scraping 4 The wood primer shall be prepared according to the required proportion in the primer construction, which can be applied by brushing or spraying The function of primer construction is to fill the wooden holes and increase the thickness of paint film During construction, after the primer is dry, it must be thoroughly polished with sandpaper, and then the primer shall be applied again It is required to paint evenly without sagging and fill the wooden hole smoothly 5 Sanding the board with sandpaper is actually a step throughout the whole wood paint construction process During plate processing, sanding is required, putty scraping is required, primer construction is required, and finishing coat is required before and after construction The sanding process is critical Sanding makes the plate smoother, smoother and easier to paint Sanding after painting makes the surface of paint film flat and smooth But pay attention to avoid cross sand during sanding, and do not use too coarse sandpaper for grinding 6 Before finishing coat construction, the wood surface must be cleaned again to remove dust particles, so that the paint film surface can have a better coating effect Each time the finishing coat is applied, it should not be too thick at one time It is better to apply it many times, and the construction of the next layer should be done after the paint film is dry The finishing coat construction directly affects the final effect of the paint film The finishing coat construction requires uniform application, no sagging, good glossiness, no obvious brush marks, and smooth and delicate feel The above is Xiangxiang Xiaobian to introduce you the basic knowledge of wood paint construction, hope to help you!
