Baking paint classification:
Baking paint is divided into two categories, a type of low-temperature baking paint curing temperature of 140 ° -180 °, the other category is called high-temperature baking paint, its curing temperature of 280 ° - 400 °.
High-temperature baking paint:
High-temperature baking paint, also known as Teflon (telon) in English, known as Polytetrafluoroetylene, referred to as Teflon, PTFE, F4 and so on. Teflon high-performance special coatings is a polytetrafluoroethylene-based resin fluorine coatings, the English name for Teflon, because of the pronunciation of the reason, usually called Teflon, Teflon, Teflon, Teflon, Teflon, and so on (all for Teflon transliteration). Teflon (Teflon) coatings are a unique, high-performance coating that combines heat resistance, chemical inertness, and excellent insulation stability with low friction, providing a combination of advantages that other coatings can't match, and the flexibility of its application makes it possible to use it on products of virtually all shapes and sizes.
Process:
Baking paint: three times primer, four times top coat on the substrate, each time the paint is applied, it is sent to the dust-free constant temperature baking room, drying.
What is baking paint
Baking paint is divided into liquid and powder, liquid is paint, powder is powder foam. Both are sprayed on by the gun and then baked.
Baking paint is what paint, used in which
Decorative decoration commonly used paint
1, varnish: mainly in the paint before doing primer.
2, the original paint: also known as lead oil, is a mixture of pigments and dry oil grinding, mostly used to mix putty.
3, blending paint: also known as blending paint, divided into two categories of grease paint and natural resin paint.
4, varnish: also known as Van Lee water, oil-based varnish and resin varnish two categories. Varieties of ester varnish, phenolic varnish, alkyd varnish, nitro varnish 5, lacquer and shellac varnish. Good gloss, fast film, wide range of uses.
6, magnetic paint: varnish and pigment grinding made of commonly used phenolic magnetic paint and alkyd magnetic paint two types.
7, antirust paint: oil-based antirust paint and resin antirust paint.
8, latex paint: paint film has a certain permeability and alkali resistance. After drying, the paint film does not blister, does not change color, does not stick, mostly used for interior wall finishing. To 9 human non-toxic, no pollution to the environment. What are the main components of paint?
The main components of paint include the following five major parts:
(1) oil: including dry and semi-dry oil, is one of the main film-forming substances.
(2) resin: including natural resins and artificial resins, is also part of the main film-forming substances.
(3) Pigment: including coloring pigment, body pigment and antirust pigment, the specific varieties are quite numerous, and they are secondary film-forming substances.
(4) Diluent: including solvent and diluent, used to dissolve the above substances and adjust the consistency, as the auxiliary film-forming substances.
(5) Accessories: including drying agents, curing agents, plasticizers, moisture-proofing agents. Also belongs to the auxiliary film-forming substances.
Decorative coatings composition:
The main film-forming substances: also known as adhesives and fixatives, is the basis for the composition of coatings.
Secondary film-forming substances: also constitutes a component of the coating film, but it can not leave the main film-forming substances and constitute a separate coating film.
Auxiliary film-forming substances: These include solvents and auxiliary materials. The former, such as gasoline, tobacco oil, rosin, benzene, ethyl acetate, acetone, etc.; the latter, such as curing agents, emulsifiers, tackifiers, drying agents, wetting agents, dispersants, defoamers, initiators, catalysts, stabilizers, antioxidants, antifreeze, and so on.
1. Paint:
Paint according to the reaction and process is divided into PE, PU, UV, NC four categories.
(1).PU is the most commonly used paint, generally divided into furniture paint and propionic acid paint. Many of us say that the furniture is not baked paint is to refer to the furniture paint. Because this kind of paint is self-drying, the cost of this kind of paint is also relatively cheap. Procyanic acid lacquer was first used for the exterior covering of automobiles and motorcycles, but nowadays, the top coat of good furniture is also used in this way, which is baking lacquer. The hardness of baking varnish can reach 2H, good finish, strong work force, small sagging, strong acid resistance, good resistance to yellowing. The practice of this kind of paint is paint + curing agent + thinner. Now said the authentic baking paint, car paint is referred to this.
(2) PE and PU compared to the reflection is not the same, is by the paint + initiator, accelerator + thinner. This paint hardness is stronger, up to 3H or more, brightness texture is better, yellowing resistance is very good. Of course, the cost of this paint is also very high. Generally referred to as gold diamond, diamond paint is referred to this. In addition, in the PE category there is a kind of inverted film paint, the cost of this paint is cheap, pay for the poor work force.
(3) UV paint: this paint is not baking paint, not self-drying paint, but a light-curing paint. UV paint is only the surface of the layer, inside or PU furniture paint (light does not pass), the cost of this paint and propionic acid paint is almost the same, because it is used in furniture paint and because this paint is instant curing, no volatility, save material. However, this paint process is more. UV paint in many performance can achieve the effect of PE, such as hardness can be up to 3H, brightness is not good. However, UV paint also has disadvantages: 1. UV paint can not be painted around, so can not paint sealing, only through the sealing strip to seal. And do paint the trigger is not moisture-proof board, but density board. Edge a little bad to allow convulsive deformation rise. 2. Because the inside is PU paint, the outside is UV, 2 different kinds of paint is not very good.
(4) NC, this paint is now basically no one, so do not introduce more. There are also sanding paint, matte, but scratch resistance is the strongest.
The so-called U v lacquer refers to the lacquer process using light-curing lacquer, Pu lacquer is the use of polyurethane lacquer. u v lacquer and Pu lacquer is the main difference between the process of processing the process of processing the different, some light-curing lacquer in the lacquer is also polyurethane lacquer. u v lacquer used in the light-curing process in the brush paint pollution-free, more environmentally friendly than Pu lacquer, from the factory flooring processing process, the health of workers and the protection of the environment has benefits, from the factory flooring processing process, the workers have a good health and environmental protection, and from the factory processing process, the flooring process, the workers have a good health and environmental protection, and from the factory flooring processing process. and the protection of the environment has benefits, from the production point of view, it ......
Sheet metal baking paint is what
Sheet metal baking paint that is for the processing of steel, aluminum, copper and other metal plates, baking paint. Baking paint is in the substrate to play three times primer, four times the surface paint, each time on the paint, are sent to the dust-free scale temperature baking room, baking.
Sheet metal so far has not been a more complete definition. According to a foreign professional journal on a definition, it can be defined as: sheet metal storage is for sheet metal (usually below 6mm) a comprehensive cold process, including shearing, punching/cutting/compounding, folding, riveting, splicing, molding (such as car body) and so on. Its distinctive feature is the same part thickness is consistent.
What is the material baking paint
Baking paint, in the manufacture of furniture in the emerging method of spray paint production (process).
The method is: sanded to a certain degree of roughness on the substrate (usually high-density sheet metal), sprayed with a number of layers of paint. And high-temperature baking and shaping. The process currently requires high paint, good color rendering.
Baking paint is divided into two categories, a class of low-temperature baking paint curing temperature of 140 ° C -180 ° C, the other category is called high-temperature baking paint, its curing temperature of 280 ° C - 400 ° C. High-temperature baking paint, the full name of the English language, Polytetrafluoroetylene, referred to as Teflon, PTFE, F4 and so on. Teflon high-performance special coatings is a polytetrafluoroethylene-based resin fluorine coatings, the English name for Teflon, because of the pronunciation of the reason, usually called Teflon, Teflon, Teflon, Teflon, and so on (are Teflon's translation).
What is baking varnish
A production process, the piano's shiny skin is basically baking varnish
What is the difference between the piano baking varnish and ordinary baking varnish?
"Piano baking varnish" actually has a double meaning, the first meaning refers to the paint itself, that is, unsaturated polyester PE high-gloss paint itself; the second meaning refers to the piano paint spraying process. That is to say, the so-called piano baking varnish is including material and process aspects, rather than just material. Let's continue to understand what is "piano lacquer". I. Piano paint as a lacquer, is a polyester paint that is a kind of PE paint, rigorous statement should be unsaturated polyester PE piano paint, is a kind of high-gloss unsaturated polyester paint. The reason for this requirement is because a variety of common lacquer, such as polyurethane PU lacquer, nitro NC lacquer, light-curing UV lacquer and so on have high-gloss mirror lacquer, just high-gloss curing principle is different. Some of these lacquers are not very easy to distinguish from piano lacquer in appearance. Here I summarize, piano lacquer is characterized by a very bright surface, easy to scrub, not easy to drop paint, not easy to oxidize, will not be in the long-term use of the lacquer surface yellowing. The disadvantage is that it is easy to stain fingerprints, easy to produce scratches in hard friction. General sellers or uninformed media, as long as you see the shiny paint will shout "piano baking paint", as mentioned above, there is more than one kind of high-gloss effect of the paint piano baking paint. So we must continue to recognize. Two. This is the key to the process. The so-called piano baking process, that is, after spraying or painting, do not let the workpiece natural curing, but the workpiece into the baking room, through the electric heat or far infrared heating, so that the paint layer curing process. However, not all baking paint is piano paint! Many merchants are exploiting this loophole, as a way to fool the media to help them advocate. In addition to piano paint can be used baking process, like PU paint, metallic paint, acrylic paint, etc. can also be used baking process production. In fact, many now playing the "piano lacquer" signboard products, in fact, and when the use of polyurethane painting process, the same products, the use of polyurethane PU lacquer is still PU lacquer, just changed to PU lacquer! The real piano paint, and ordinary baking paint is different, it is a multi-channel baking paint. Piano paint needs multiple coats, which is caused by the characteristics of PE paint itself. Compared with PU paint, PE paint has a light color and high transparency, and needs multiple coats to achieve the effect we see. Generally speaking, the real piano paint is at least three coats of paint, while the piano paint used on brand-name furniture is at least five coats of paint, and as for the real piano, its paint is actually more than 10 coats of paint! This brings a characteristic of real piano paint - due to the number of paint channels is extremely high, so the thickness of the piano paint layer is much thicker than other baking paint, and due to the characteristics of PE paint itself (PE paint can not be sprayed thin film, otherwise easy to deformation), it is much higher than the thickness of each paint PU and other paint. Even the primer and leveling the surface of the workpiece with the putty are counted, the real piano paint, the thickness of its completely reached the naked eye can see the degree of the number of layers. If you go through such a complicated procedure to apply piano lacquer, there is of course a reason why you have to do it. Compared with other high-gloss paint coating, piano paint has the highest hardness and brightness, adhesion and chemical properties are also very stable, especially important is that the piano paint does not use hardener, so basically there will be no hardener caused by the paint surface "yellowing" phenomenon. This is other high-gloss mirror paint can not be compared. Piano lacquer to achieve its effect, "piano lacquer" itself and "piano lacquer process" is indispensable, less any one, the effect will be greatly reduced. There are two ways to recognize piano lacquer, but both are destructive. Piano lacquer is actually like a piece of enamel, hard and brittle, vigorously knocked on the surface of the lacquer, the damaged area will only fall into a piece of debris, rather than falling off a piece of film. From this point can be judged, the piano paint is actually only suitable for some infrequent moving things, such as some mobile projector like daily carry, I think to really real piano paint, probably not a week will not be the shape. Baking paint through the high temperature process, so baking paint surface can withstand a short period of fire without major damage, and spray paint, especially PU spray paint is not. In fact, we can also be a simple judgment, where the workpiece itself can not withstand high temperatures, it is never above the piano paint, otherwise the workpiece early in the paint room melt away. So the second way to recognize is to "bake" it! Ideal piano paint, that is, "real piano" paint, the most important feature is in fact a complete mirror effect, although in the brightness can not be compared with the mirror, but the surface should be completely flat and smooth, reflecting the reflection does not exist half a point of distortion. This effect is in addition to the piano paint, any kind of high-gloss paint treatment (whether it is the use of non-baking paint treatment PE paint, or other categories of baking paint) can not do. It is also the reason why piano lacquer is so noble and irreplaceable. But this ......
What is baked plastic? What is the difference between baked plastic and baked paint?
Baked plastic field process
Before baking plastic, the substrate for surface treatment. After the treatment is completed, it is transferred to the dust-free spraying table, and then sprayed with environmentally friendly plastic powder, and evenly covered in the surface of the substrate. Finally, put the substrate into the oven at high temperature baking, general baking time should last at least one hour or more.
Substrate surface treatment
At present, there are two main ways of surface treatment: First, potion phosphating. This way to use less, the potion will cause pollution, the environmental protection department requires higher. Second, shot blasting, divided into two kinds of rolling and hanging throw, inside the machine will be metal particles hit the surface of the substrate, the substrate surface stains off.
Precautions
Due to the high requirements of the baking molding, you must use a dust-free spray booth. If mixed with debris, after baking plastic surface debris particles will appear obvious, belong to the defective products.
The difference between baked plastic and baked paint
The so-called baked paint, is generally cured by spray paint. Baked paint surface smooth and beautiful, but the paint film is thin, poor adhesion, wear-resistant performance is poor, very easy to bruise and scratch. Baking plastic powder film thick, but the surface is not as bright as baking paint, but the substance of a good sense of adhesion, wear-resistant and durable, is baking paint is far from reaching. In addition, baking paint is a chemical substance, containing many chemicals (such as stupid elements, etc.), not environmentally friendly. Baking plastic powder used in plastic, is an environmentally friendly material!
Edit paragraph baked plastic in the life of the use
Now with the baked plastic technology continues to develop and mature, many cars have adopted the baked plastic technology. Because of environmental protection (very low VOC), high utilization efficiency, automation and other advantages. It can be said that baking plastic is a new industry, later in many areas will replace the existing baking paint process, especially some baby products, now the concept of environmental protection continues to strengthen, people's demand for green and healthy is also increasing!
What is baking paint door
Baking paint door
Baking paint, that is, after spraying paint into the drying room heating and drying process of paint door panels. Its advantages are bright colors, with a strong visual impact, good surface finish, easy to scrub,
Moisture-proof, fireproof performance is good. Baking paint door more density board as a substrate, the back of the three polyhydrogen amine, complex technology, processing cycle is long, the price is relatively high. High-grade PU baking
The type of lacquer door is divided into piano lacquer and metal (automotive) lacquer two kinds of skeleton metal lacquer is better than the piano lacquer.
As the surface of the paint quality is difficult to identify, if they claim to be high-grade PU (polyester) paint, but the price is very low, it can be judged, the use of high-grade environmentally friendly paint
Almost impossible. Choose lacquer door do not for the temporary surface of the moment brightness confused, when you have had the feeling of using low-grade lacquer door, you will find in the fumes of pollution,
time may not be long discoloration, gloss will gradually disappear.
Baking paint door substrate for the density board, the surface after eight spray baking imported paint (three bottom, three sides, two light) high temperature baking and become a process, that is, after spraying the paint into the drying room heating and drying of the paint treatment substrate door panels. Baking paint plate is characterized by bright colors easy to modeling, with a strong visual impact, very beautiful and stylish and excellent waterproof performance, stain resistance, easy to clean. The disadvantage is the high level of craftsmanship requirements, high scrap rate, so the price remains high; the use of careful care, relatively afraid of bumps and scratches, but the damage is very difficult to repair, to be replaced as a whole; more suitable for the appearance and quality of the requirements of the higher, the pursuit of fashionable young upscale consumers.
What is baking paint baking paint process
In life, perhaps we can often hear people say car baking paint, baking paint glass, baking paint plate and other words, when listening to say, many consumers are confused, what is baking paint? Many people even think that baking paint is a process of treatment, this understanding is wrong? Let's take a look at what is baking paint and baking paint process how. ◆ What is baking paint 1 What is baking paint? The so-called baking paint, in fact, is also a kind of paint coating, strictly speaking, baking paint is a kind of paint. In the current application, baking paint is divided into two categories of low-temperature baking paint and high-temperature baking paint, of which the actual application of low-temperature baking paint is less, high-temperature baking paint is widely used.2 High-temperature baking paint introduction Since the high-temperature baking paint is widely used in practice, then the main high-temperature baking paint is introduced here. Teflon (Teflon) English full name Polytetrafluoroetylene, this term is another name for high temperature baking paint, this is a polytetrafluoroethylene as the base resin fluorine coating. In addition to Teflon, high temperature baking varnish has a variety of names, the performance of this fluorine coating performance is very excellent, low friction, insulation stability, chemical inertness and heat resistance are perfectly combined in one, so in the industry is widely used. ◆Baking paint process to understand the baking paint process, from the baking paint process and baking paint room to study two aspects, because the two in the actual application of the contact closely, so the baking paint process and baking paint room combined research, to be able to better grasp the baking paint process. 1 baking paint process for many people think that the baking paint is a kind of process processing mode of view, in fact can not be counted as a mistake, in fact, baking paint can be said to be both a kind of paint, the baking paint can be said to be a kind of paint, the baking paint is a kind of paint. Paint can be said to be a kind of paint, can also be said to be a kind of process. Detailed baking paint process is: every paint on the substrate, it is sent to the dust-free constant temperature baking room for drying, and so on three times, four times or more. 2 baking paint room baking paint room is a kind of industrial device, its structure adopts the assembled structure, the room body is made of mother and child plug type heat preservation and spraying wall panels, with good sealing and heat preservation, in the side of the room body there is a working door which is convenient for the staffs to go in and out, and also equipped with an aluminum alloy wrapped door, the central door is equipped with an aluminum alloy wrapped door, and the central door is equipped with an aluminum alloy wrapped door. Aluminum alloy cladding large door, the door is equipped with observation window in the center and other configurations, and its only function is to be used for baking paint process. In the above content, we can see that baking paint is with two kinds of interpretation, both can only a type of paint, can also be said to be a process. Therefore, some of the ideas that people often say are not wrong, just not accurate. Through the above introduction, for what is baking paint and baking paint process how the information you must have a more intuitive understanding, I hope to help you.
