What should I do with the inside of the lacquered door panel?

The production process of the painted door panel:

The painted door panel is mostly made of MDF as the base material, the back side is triamine, and the surface is baked at high temperature by six spray baking imported paint (three bottoms, two sides, and one light). The process is complex, the processing cycle is long, and the ** is relatively high. The types of high-grade PU paint doors are divided into piano paint and metal (automobile) paint, and metal paint is better than piano paint.

Basic procedure: The substrate is MDF, and the surface undergoes a series of processes such as grinding, polishing, lacquering, entering the paint room, and drying.

Production process: 1. Cutting materials; 2. Trimming; 3. Gong fancy; 4. an opening; 5. White billet sealing; 6. white billet sanding; 7. a first primer; 8. The first primer sanding; 9. a second primer; 10. The second primer sanding; 11. a third primer; 12. a third primer sanding; 13. a water mill; 14. a first topcoat; 15. baking; 16. a water mill; 17. a second topcoat; 18. baking; 19. a water mill; 20. a cover light; 21. baking; 22. cooling; 23. maintenance; 24. Packaging. Application Features::

1. There is no edge banding, which is divided into single-sided baking paint and double-sided baking paint. The waterproof place is painted with edge sealing, and the surface is shiny.

2. The overall effect is good, and there is no oil stain. It is generally divided into bright, matte, and pearlescent. The most visually striking.

3. The high grade is not easy to deform, and it can be used as a bathroom cabinet, which is easy to clean and improve the brightness of the room.

4. Spray painting: The door panel made of polyester paint through the spraying process does not need to bake the surface, and it is matte after it is made. Baking paint can generally be modulated more than 30 colors, and the best baking paint process is currently Italy.

5. The disadvantage is that the process level is high, the rejection rate is high, and the first is high; It should also be carefully cared for when used, for fear of bumps and scratches, once it is damaged, it is difficult to repair, and it should be replaced as a whole; Kitchens with a lot of oil smoke are prone to color differences. It is more suitable for young high-end consumers who have high requirements for appearance and quality, and pursue fashion. When cleaning, be careful not to scrub with steel wool balls, so as not to leave scratches and the scratches are too heavy to repair, and the powdery substance will fall off if you hit it with gravity.

You can choose in the iron block, you don't first engrave the text, and then bake the lacquer.

I don't understand what you mean?

The choice is important, and the effort after the choice is even more important.

On a substrate that has been sanded to a certain degree of roughness (usually high-density sheets), several layers of paint are sprayed. And it is baked and shaped at high temperature. At present, this process has high requirements for paint and good color rendering.

Baking paint is divided into two categories, one type of low-temperature baking paint curing temperature of 140 °C-180 °C, the other type is called high-temperature baking paint, its curing temperature is 280 °C-400 °C. High-temperature baking paint, the full name of polytetrafluoroetylene in English, referred to as Teflon, PTFE, F4, etc. Teflon high-performance special coating is a fluorine coating with PTFE as the matrix resin, the English name is Teflon, because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon and so on.

Distinguish between baking paint and spray paint:

b. Painting: Grinding the tweed on the substrate, then spraying paint on it, and drying it naturally.

Second, the paint film. Method: Touch the edges and corners of the painted door panel with your hands to see if it is smooth and proof; Observe the color of the edges and corners to see if they are the same color as the door panels.

Contrast: a. Baking paint: smooth edges and corners, the same color. It proves that the paint film is uniform and the color is full.

b. Spray paint: the edges and corners are rough, and the color is lighter than the door panel. Proof that the paint film is uneven and the color is not full:

3. Texture. Method: Compare the light to see whether there is orange peel on the surface of the painted door panel.

Contrast: a. Baking paint: the surface of the door panel is smooth, without texture and orange peel.

b. Spray paint: the surface of the door panel has lines, not smooth, and there is orange peel.

Fourth, the surface. Method: Touch the surface of the painted door panel with your hands to see if there are dust particles and bubbles.

Contrast: a. Paint: The surface of the door panel is flat and smooth. $_gwo2

B. Painting: There are particles on the surface of the door panel, which is not smooth, and there is a peculiar feeling to the touch.

5. Wear-resistant. Method: Hit with a hard object.

Contrast: a. Baking paint: no abnormal situation, no damage to the paint film.

b. Spray paint: there are cracks, serious paint film peeling off, white skin falling.

Structure and working principle of paint baking room.

Paint room structure.

The whole paint room is an assembled structure. The body of the house is made of plug-in insulation spray plastic panels, which has good sealing and thermal insulation performance, and is equipped with a working door on the side of the body to facilitate the entry and exit of staff; Aluminum alloy edging door, the door ** is equipped with an observation window, which can observe the dynamics of the room at any time. Choose a low-noise and high-volume fan to ensure the perfection of the painting effect; High-quality stainless steel heat exchanger, high heat exchange efficiency and long service life.

The working principle of the paint room.

The paint booth is generally used to spray and bake car paint, so the most accurate description of the paint booth should be "spray paint room".

When painting, the outside air is filtered by the primary filter and then sent to the roof by the fan, and then filtered and purified by the top filter before entering the room. The air in the room adopts a full descending type, which flows downward at a speed, so that the paint mist particles after spraying cannot stay in the air, but are directly discharged from the room through the bottom air outlet. In this way, the continuous circulation conversion makes the air cleanliness in the room reach more than 98 when painting, and the air sent in has a certain pressure, which can form a constant air flow around the car to remove excess paint, so as to ensure the quality of painting to the greatest extent.

When baking the paint, the damper is adjusted to the baking position, the hot air is circulated, and the temperature in the baking room quickly rises to the predetermined drying temperature (55 -60). After the fan filters the fresh air outside, it is sent to the air chamber at the top of the paint room after heat exchange with the heat energy converter, and then filtered and purified for the second time, the hot air passes through the internal circulation of the air damper, in addition to sucking in a small amount of fresh air, most of the hot air is continued to be heated and utilized, so that the temperature in the paint room gradually increases. When the temperature reaches the set temperature, the burner will stop automatically; When the temperature drops to the set temperature, the fan and burner are automatically turned on again, so that the temperature in the paint baking room remains relatively constant.

Finally, when the baking time reaches the set time, the baking room will automatically shut down and the baking will end.

Baking paint, an emerging painting production method in furniture manufacturing.

The method of making it is to spray several layers of paint on a substrate that has been sanded to a certain degree of roughness (usually a high-density board). And it can be baked and shaped at high temperature.

Every time the paint is applied to the substrate, it needs to be sent to a dust-free constant temperature oven for baking, and so on three times, four times or more. At present, this process has high requirements for paint, and requires good color rendering of paint. The above is the answer for you.

1. The substrate is MDF, the substrate is 18mm MDF, and white melamine paper is pasted on both sides;

2. Carry out engraving and milling according to the door type selected by the customer;

3. After the milling is completed, do a sealing paint in the bottom part of the leakage;

4. Polishing and spraying white primer;

secondary grinding for coloring;

6. Repeat 8-9 times of grinding, polishing and spraying;

7. Finally, a bright paint should be sprayed;

8. Water grinding;

9. Polishing with polishing wax;

10. If the process is in place, the adhesion of the paint film covered is very firm, not easy to fall off and the paint film is full;

11. Fixed packaging.

Medium density is used as the base material, after milling and grinding, the surface is painted, and the cabinet doors of various colors are mainly made by manual type. This is the whole process of making the so-called lacquered door panels.

The substrate of the paint board is generally multi-layer plywood or high-density board, and the surface is polished six to nine times (different manufacturers have different times, the more times the process requirements, the higher the cost), primer, drying, polishing (three bottoms, two sides, one light) high temperature baking.

Lacquered board is a type of woodworking material. It is based on MDF, and the surface is polished six to nine times (different manufacturers have different times, the more times the process requirements, the higher the cost), primer, drying, polishing (three bottoms, two sides, one light) high temperature baking.

Mainly used in cabinets, doors, etc. Lacquered boards can be divided into three types: glossy, matte and metallic.

Process. Medium density fiberboard sizing.

Shape the surface of the MDF, make various patterns or do not do pattern polishing, and smooth with sandpaper.

Brush closed bottom. Sanding spray primer.

Go into the baking room and polish it.

9. Spray paint.

Go into the baking room and polish it.

Spray topcoat to illuminate.

Go into the baking room and grind the water.

Imported wax is polished and the finished product is completed.

Advantages 1, bright colors, and a variety of choices 2, can be matched with a variety of collocation, color intertwined, to achieve the effect of buyers. 3. Easy to clean and care for 4. A good painted door panel is much stronger than the crystal door panel with UV resistance. 5. It has a certain role in supplementing the space of the kitchen.

Disadvantages: The production cycle is too long, the process level is high, and the rejection rate is high, so it is difficult to repair once it is damaged, and it must be replaced as a whole; Kitchens with a lot of oil smoke are prone to color differences.

The differences between UV door panels and painted door panels are: UV door panels, different production methods, and different characteristics.

First, the functions are different

1. The UV board is the plate whose surface has been protected by UV treatment. UV paint is ultraviolet curing paint, also known as light-initiated coating.

2. Painted door panels are the most widely used cabinet door panels. That is, the paint door panel that enters the drying room after spraying and enters the drying room.

Second, the production method is different

1. UV board is formed by UV paint on particleboard, MDF and other boards, and then dried by UV light curing machine, because it is easy to process, can realize industrial production, bright color, wear resistance, strong chemical resistance, long service life, high requirements for mechanical equipment and process technology, and has the characteristics of moisture resistance and deformation.

2. The paint door is mostly made of MDF as the base material, the back side is melamine, and the surface is baked at high temperature after six spray baking imported paints. The process is complex, the processing cycle is long, and the ** is relatively high.

Third, the characteristics are different

1. The primer of the UV board is a solvent-free 4E green high-grade coating, which is non-volatile, non-toxic and environmentally friendly; After curing, it has a high-gloss antibacterial effect, which is an ideal decorative board.

2. The advantages of the painted door panel are bright color, strong visual impact, good surface finish, easy scrubbing, waterproof and moisture-proof, and good fire performance.

Uses of UV boards:

1. Furniture: panel furniture, living room furniture, bedroom furniture, study furniture, children's furniture, kitchen furniture.

2. Tables and chairs: large class desks, student desks and chairs, desks, lecterns, desks, conference tables, computer desks.

3. Decoration: interior decoration, interior murals, photo frames, art photos, landscape decorative paintings.

4. Office: staff desks, computer cabinets, front desk desks, company indoor billboards.

5. Sliding doors: flat door panels, compartment panels.

6. Others: exhibition hall furniture, shopping mall counter furniture, shopping mall partitions, handicrafts.

UV paint is a kind of paint, although it is the same UV board or UV paint, but different manufacturers produce different processes, its quality is not the same, UV board needs edge banding, because it is made of particleboard as the base material, a layer of UV paint outside, and then a layer of film. However, the baking paint is based on MDF, and the moisture-proof performance of MDF is poor, so the paint layer is very important, including the quality of the paint, the baking process, and the flatness of the surface of the baking paint. Some bake it once, and some say that the paint is baked paint.

1. Compared with the traditional paint door, the UV paint door technology is more advanced and the quality is more advanced.

Second, the advantage of traditional baking paint products is that the color is bright and has a strong visual impact. The disadvantage is that the current domestic technical equipment still needs to be updated and improved, because of the high technical requirements of the product, the rejection rate is high. At present, domestically manufactured painted door panels require expensive manufacturing equipment and complex technological processes.

Third, the new UV paint door panel production equipment and technology using foreign advanced production mode, the first German automotive paint technology successfully introduced into the cabinet panel production process, high paint efficiency, the gloss and fullness of the coating surface is high, the mirror is clearer, the coating adhesion is strong, and the cabinet technology has achieved five breakthroughs. First, the surface hardness is high, the anti-aging ability is strong, and the durability is long; Second, the case is treated with high-gloss clear oil, which can effectively prevent acid and alkali corrosion; Third, the surface is smooth and clean, without small scales, which fully shows the perfection of the technology; Fourth, it has strong ultraviolet resistance and is not easy to fade, which is much better than the traditional poly paint process; Fifth, the product has a good environmental protection effect. Because the surface of the panel made by this technology is smooth and impermeable, it can effectively prevent the volatilization of harmful substances such as formaldehyde and benzene inside, and its products can meet international environmental protection standards.

Fourth, the new UV baking paint compared with the traditional baking paint has a major advantage is that the traditional baking paint uses a higher temperature to heat the wood board to make the paint solidify, because the wood has a certain moisture content, so the wood board is easy to deform after heating, and it is difficult to recover after deformation, resulting in waste and high cost, and has high requirements for the quality of the wood board substrate, and the new UV baking paint can avoid the defects of this traditional baking paint, with the characteristics of cold and warm curing, 3 seconds of rapid curing, etc., so it can reduce the quality requirements of the board. Any panel substrate can produce a qualified cabinet lacquered door panel.

5. UV baking paint molding material has the advantages of no fading, no deformation, no falling off, ultraviolet resistance, and high brightness. In addition to the application of cabinet items, it can also be widely used in furniture, various wood, natural stone, artificial stone, metal, leather and other surfaces.
