Paint knowledge: main categories, advantages, disadvantages and application scope of furniture paint

Core tip: at present, the main categories of furniture paint widely used in the market are: nitrocellulose paint (NC), UV curable paint (UV), acid curable paint (AC), polyurethane paint (PU), unsaturated resin paint (PE), water-based paint (water) Let's take a look at the advantages and disadvantages of various categories of furniture paint and the scope of application together with Xiaobian 1、 The main categories of furniture paint nitrocellulose coating (NC) advantages: 1, fast drying The drying time of general paint needs to pass through 24 hours, while that of nitrocellulose paint can be dried as long as 10 minutes This will greatly save construction time and improve work efficiency Two Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home of coatings: at present, the main categories of furniture paint widely used in the market are: nitrocellulose paint (NC), UV curable paint (UV), acid curable paint (AC), polyurethane paint (PU), unsaturated resin paint (PE), water-based paint (water) Let's take a look at the advantages and disadvantages of various categories of furniture paint and the scope of application together with Xiaobian 1、 The main categories of furniture paint nitrocellulose coating (NC) advantages: 1, fast drying The drying time of general paint needs to pass through 24 hours, while that of nitrocellulose paint can be dried as long as 10 minutes This will greatly save construction time and improve work efficiency 2 Simple construction Nitrocellulose coating is a single component product, which can be sprayed by adding proper amount of Tianna water 3 Stable luster: less affected by the environment Disadvantages: 1 Insufficient fullness Due to the low solid content of nitrocellulose coating, it is difficult to form thick film 2 The hardness is not enough The hardness of nitrocellulose coating is generally in BH 3 The film surface is not solvent resistant Common processes: 1 NC bottom and NC surface It is widely used in antique furniture (American painting) Most of the performance effects are open 2 Pu bottom, NC surface This is easier to solve: NC paint filling force is poor, fullness, hardness is not enough Construction method: 1 Dip coating 2 Spraying (including electrostatic spraying, manual spraying, computer automatic spraying) 3 Roll coating Future development: 1 The yellowing resistance of NC paint is relatively poor But at present, it has been able to withstand the NC solid color paint with constant yellow for 2 years 2 Hardness of NC paint Now, the paint manufacturing enterprises with sand are under special research More than 2h of NC paint will be available soon 2、 The main categories of furniture paint acid solid coating (AC) advantages: 1 Hard and wear-resistant paint film 2 The heat resistance, water resistance and cold resistance of the paint film are all very high 3 Good transparency 4 Good yellowing resistance Disadvantages: due to the free formaldehyde contained in the paint, the body injury to the constructor is more serious, and most enterprises no longer use such products 3、 The main categories of furniture paint unsaturated resin coating (PE) advantages: 1, with good hardness, can reach more than 3H 2 The finish can give a high gloss 3 Acid and alkali resistance, wear resistance, good heat resistance 4 The fullness is very high Disadvantages: 1 The operation is more complex because the initiator and accelerant need to be added to play a curing role The amount of initiator and accelerant should be changed according to the change of temperature and humidity In addition, the initiator and accelerant cannot be mixed into the paint at the same time, otherwise it is easy to cause fire and explosion There are strict requirements when preparing paint 2 The active period of the prepared paint is very short, and the prepared paint must be used up within 25 minutes 3 At present, there are only bright products and no matte products for PE finish Common technology: 1 PE bottom, PE surface; very high fullness and hardness, commonly used in musical instruments, crafts, cabinets, speakers 2 PE bottom, Pu surface; high fullness, good anti sinking performance, commonly used in office furniture countertops and high-end suite furniture (such as new classical furniture series) Future development: 1 Now PE automatic spraying equipment has been popularized and applied in some furniture factories 2 The drenching of PE paint, because of the problem of activation period, has been beset furniture enterprises But at present, this problem has been solved in the construction process, that is, let the mixture of the initiator and the accelerator react on the panel to achieve leveling and curing 4、 The main categories of furniture paint polyurethane coating (PU) advantages: 1, fullness, hardness, transparency, have better performance 2 Stable performance, high product stability 3 It can cooperate with other paint varieties to make different performance effect, which is a kind of paint with excellent comprehensive performance It is also the most widely used Disadvantages: 1 Poor workability compared with NC paint 2 Fullness and hardness are worse than PE paint Common process: 1 Pu bottom, Pu surface: the most common process 2 PE bottom, Pu surface: high fullness, anti sinking, suitable for high-grade furniture production 3 Pu bottom and NC surface: good fullness and fast construction 4 UV bottom, Pu surface: the most promising technology, high efficiency, excellent product quality 5 Pu bottom and W surface: it has certain fullness and strong environmental protection Common construction methods: 1 Spray (hand spray, computer spray) 2 Primer roll coating (not commonly used) 3 Drench (bottom, surface) 5、 The main categories of furniture paint UV curing coating (UV) advantages: 1, for the current one of the most environmentally friendly paint varieties 2 High solid content 3 Good hardness, high transparency 4 Good yellow resistance 5 Long activation period 6 High efficiency, low coating cost (normally half of the conventional coating cost) is dozens of times of the conventional coating efficiency Disadvantages: 1 Large investment in equipment 2 It is necessary to have a sufficient supply of goods to meet its production needs, and continuous production can reflect its efficiency and cost control 3 The effect of roller topcoat is worse than that of Pu topcoat 4 Roller coating products require the coated parts to be flat Common technology: 1 UV bottom, UV surface 2 UV bottom, Pu surface (most widely used) Common construction methods: 1 Roll UV bottom and spray Pu surface (solid color and transparent paint are acceptable) 2 Spray UV bottom, spray UV surface (solid color, transparent paint is OK) 3 Roller coating uv bottom, roller coating UV surface (solid color, transparent paint is OK) 4 Roller coating uv bottom, spray coating UV surface (solid color, transparent paint is OK) Home of coatings focuses on coatings, paint coatings, coating technology, news and information of fire retardant coatings, coatings, coating technology, decoration knowledge and decoration renderings of fire retardant coatings,
