Since the beginning of 2002, at the national furniture industry focus areas, the use of UV paint manufacturers more and more. Chengdu, the local representative of several furniture companies, the Pearl River Delta region, a number of enterprises, with Shanghai as the center of the Yangtze River Delta and Beijing, some of the furniture industry begun to take shape over the past two years are using the UV paint.

   UV lacquer painting and furniture used in the traditional PU paint, PE Chatham, NC Chatham ways in the course of construction, performance, cost, production efficiency, such as to have a greater difference, not everyone is familiar. What is UV paint? UV What are the characteristics of paint? With the traditional PU, such as paint what difference? In the furniture industry prospects? How good UV paint? Of these issues be summarized as follows:

   About UV lacquer

   UV lacquer is Ultraviolet Curing Paint abbreviation. That is, UV-curable paints, also known as Photoinitiators coatings, light-cured coating. With PU, PE, NC to film-forming substances such as paint named in different ways, UV lacquer painting is named after the curing methods. It is through the machinery and equipment automatically roll Tu, Tu leaching into the surface of furniture board, in the ultra-violet light (wavelength 320-390nm) of irradiation to initiator decomposition, producing free radicals, triggered resin reaction, instant film curing.

   20th century 60's in the Western industrialized countries have begun to use the application in China began in the furniture industry, or the 20th century, the mid-90s thing. At that time, some large-scale enterprise spending huge sums to introduce the entire UV-ray, such as the Shenzhen-ho, Tiancheng, Dongguan Dixon, Fu Yun, etc.. At that time, because of technical conditions, such as restrictions on imports can only use UV paint, prices high, the use of personnel requirements, painting the service providers can not keep up, UV paint only in these large-scale furniture manufacturers in the use of, and not Each factory can truly use it well. China-made equipment in recent years due to mature, to Shenzhen, Kim Young, represented by some companies after years of effort, so that UV paint manufacturing technology has reached international standard, and some products have been a world leader. Furniture Factory for competitive pressure to improve efficiency, reduce costs, meet environmental requirements of consumers, one after another the introduction of UV-ray, the use of UV paint, UV paint only for the general public contacts, will also be facing an unprecedented good time.

   The advantages of UV lacquer

   1, green environmental protection

   UV lacquer solid content of more than 95%, non-use of volatile organic solvents, which contain components of all curing film. Construction of the operator of the health hazards and environmental pollution are the lowest, is the real green environmentally friendly products. And we used paint polyurethane (PU paint), unsaturated polyester paint (PE Chatham) and distempers Mastics (NC lacquer), in the course of construction, nearly half of the solvent (such as toluene, xylene, ketones, ester, styrene) and free monomer (such as free toluene diisocyanate TDI) evaporation into the air, pollutes the environment, endanger human health. July 1, 2003 national enforcement PU mixture of free toluene diisocyanate (TDI) content to less than 0.7%. It is because of the substance inhaled easily assembled after the body and affect the nervous system, reproductive system, digestive system. At the same time, a number of international traders, such as furniture, such as Sweden's Ikea also recently signed an agreement on sustainable development of their cooperation in the furniture factory working hours from workers, wood procurement sources (whether they are乱砍乱伐), work environment provides detailed standard. The use of UV lacquer is to meet this standard, the use of UV paint products in Japan and other countries despite the high prices than similar products, but very popular, hot.

   2, low cost

   In the past two years the furniture industry, although the competition is not like electrical appliances and other industries, like the brutal price war, but also become increasingly fierce. In addition to the sales network, brand building, logistics, style, quality and other aspects of competition, price competition is still the key factor, so to increase productivity, reduce costs is the most important furniture manufacturing and sales. The use of traditional PU, PE, NC, such as furniture, paint, paint materials costs account for 7-20% (including loss included), a larger proportion.

   UV lacquer high solid content, all film, construction of which has no wear and tear. The use of UV lacquer cost savings than the use of traditional paint 20-50%. Advantage is obvious.

   3, high efficiency

   Furniture styles, colors, the prevalence of short life expectancy, whether it's furniture factory is designed for traders want a new product to market as soon as possible to earn higher profits in the initial stage. Therefore, regardless of their own furniture factory has just launched a new product orders or production, the requirements of the production cycle is very short, especially some large traders to place orders, the number of large, short delivery time, making some furniture factory look alone they can not afford, did not dare to pick up.

   How to improve the productivity of furniture and shorten the production cycle it? Key is to paint coating the process.

   A product of the production cycle by the production process of one of the slowest to decide. For instance, a section of pipeline and some aspects of speed is 12m/min, while others link is 3m/min. Well, this line of production cycle rather than by the fastest average speed for some or determined, but by the slowest period of 3m/min to decide. Similarly, the production process in the furniture, furniture factory procurement back medium density fiberboard or particleboard, plywood, veneer, paper and metal pieces and so on, through the modernization of machinery and equipment is expected to open, drilling, and pasted paper, packaging, manufacturing processes than those short, while the coating of paint because of PU, PE, such as paint drying time constraints, manpower constraints, the longest of this process, the entire process of furniture production "bottleneck."

   UV lacquer coating, in the ultra-violet curing moment of irradiation, without waiting for paint dry, greatly improving the efficiency of production and to break the "bottleneck." A complete UV-ray, from the end of coloring, drying, and putty, so primer, sanding, repair paint color to paint can be completed within 3-5min. With such a UV line, eight workers can produce eight hours of disassembly 1-1.5 container furniture.

   
   5, save resources

 The use of UV paint, to facilitate mechanized operations, product curing moment, we can packaging, saving a great deal of manpower and space.

   6, performance

 UV coating is a three-dimensional structure, hardness, good abrasion resistance, transparency, and mechanized equipment to overcome the manual operation of the human factor to make our products less color, quality and stability.

   UV lacquer limitations

   V Chatham Despite many advantages, but not everyone can buy furniture factory UV lines, make good use of UV paint, UV-ray there are many defects. Limiting UV lacquer furniture factory in some use.

   1, equipment expensive

   Import a complete UV-ray, such as Italy, Roubini Faso, Italy United States, Germany, Barker, and Spain's巴贝兰and so on, from the thick plate is scheduled sanding, staining, drying, Tu putty, Tu primer to primer sanding, repair color, paint finish, the entire line configuration perfect, need to 700-1000 million yuan, that is, associated equipment, such as Taiwan, Sigmatel, also have more than two million, which undoubtedly limits the number of small and medium-sized furniture factory the use of, this is not PU lacquer UV paint the main reason for such rapid development.

   2, the use of narrow, some effects, such as paint and PU have a certain gap.

   UV lacquer coating machine, only applies to flat-panel disassembly of furniture, for some special-shaped pieces are powerless; products in the fullness, the hand and so on with PU lacquer has some gaps.

   3, energy-consuming and more

   A complete line of UV, all equipment necessary to achieve the rated power consumption 400-500 kilowatt / hour a month with 100,000 kilowatts / hour, and roll, UV lamps are consumables, requiring regular maintenance, replacement. Only orders for manufacturers to ensure adequate in order to play its role, otherwise more harm than good because the current labor force in China is still relatively inexpensive.

   4, on the technical requirements for construction workers high

   Construction personnel requirements should not only understand painting, crafts, wants to know the machinery and equipment operation, maintenance, maintenance. This is still more a lack of staff have left some furniture factory after spending huge sums as a result of the introduction of UV-ray lack of technical personnel, not willing to tie in with the paint suppliers, with UV-ray can not be good to play a role. With UV lacquer can not increase productivity, but also can not reduce costs, can only deplore the UV line before looking at there.

   UV paint the status quo and development trend

   1, UV paint the status quo

   Small scale: At present, the production of UV lacquer furniture manufacturers rarely, in addition to Kim Young-enterprises such as Shenzhen, the production scale is very small. General production capacity of 200-500 million / month.

   Varieties of small, poor product support: For instance, some water-based UV paint, UV paint spraying, it is UV color paint manufacturers even less. Light, such as roller coated varieties also fail.

 The quality is not high: with Europe and the United States and Japan there is still a certain gap.

   2, future prospects

   UV paint as a result of the above-mentioned environmental protection, low-cost, easy to mechanized operation, high efficiency advantages, more and more attention has been dubbed "the 21st century green industry of new technologies." Some large-scale furniture factory as early as the 20th century 90's introduction of UV lines, has already played a great role, and some even bought furniture factory second and the third UV line, the last two years in addition to a certain size, strength, manufacturers UV line to buy the whole, some small and medium-sized enterprises also have to buy some China-made equipment, training staff, and explore the technology, for the next step to buy the whole line to prepare for UV. UV paint market prospects, some foreign chemical enterprises have set up factories in China, such as the world's second largest paint company - PPG in Tianjin, the United States, Germany Kunlun, crown, Kennedy husband, also a member of the Shanghai and other places set up production plants in wood UV Chatham. Foreign companies are vying to set up factories in China, it is seen the UV paint is an emerging industry, in a development period, a vast future market.

   With foreign chemical companies to set up factories in China compared to some domestic enterprises have also not far behind, in recent years on the UV lacquer items, some far-sighted enterprises 10 years ago and began their own research and development, such as electronic devices Chenbro businesses years of exploring, learning, innovation, already have their own characteristics. Its products in the type of matching, quality, etc. With the rapid development of some products have achieved an international leader. For example, electronic equipment factory Chenbro independently developed UV roller coating machine, UV curing machine, leveling machine, infrared dryer and so on, in a number of furniture factory is ripe for use, overall performance has exceeded imported equipment. But it also has proposed to buy gifts UV machine UV paint, buy a machine control technology, the sale of machines to buy one-stop service that truly promote the country's UV trend

   UV lacquer classification

   From the way UV lacquer coating is divided into: UV roller coating paint, through the roller coater achieved; leaching UV coated paint, pouring through the realization of coater; UV paint spraying, by spraying or manual operation.

   According to the scope, UV paint divided into: stickers category; paste veneer category.

   UV paint several typical process (see the original form)

   Furniture Factory to introduce complete the basic requirements for UV equipment

   1. Furniture must be a panel furniture.

   2. Products less can give full play to advantages of UV-ray. If the product is a small number of a wide range of non-stop color, transfer machine, UV-ray at this time do not come out to play advantage, a product for the best boot for more than four hours.

   3. The number of products shipped to be big. Does not have sufficient orders to ensure that, UV-ray energy, and depreciation charges, and not be able to demonstrate its advantages.

   4. Product requirements can not be too high. The use of machine operators, although excluded from the artificial construction of factors, can do color uniform, but the equipment has its limitations, can not fully substitute for manpower. On hand, the degree of surface effects Fengman demanding products, but also to rely on artificial to achieve.

   5. The more input devices, process the more perfect, the more obvious cost advantage.
 
   UV paint application in the furniture industry to introduce

   The furniture industry, long-term use of paint is PU, PE, NC, etc., by spraying the construction, low efficiency, high cost and pollution of the environment, affecting the health of construction workers. In the past two years the use of UV paint manufacturers more and more, and will be the future trend of development.

   Furniture Factory in line when the introduction of UV can not follow the crowd, according to their specific circumstances, decided to invest and return. There are many manufacturers to buy UV line, impatient for success, as the technology of unskilled personnel to master the machine capacity of poor, can not be good to play a role, I feel the use of UV paint is not as efficient and cost-effective legendary, but cumbersome and complex , it also shelved and ignored, but also returning to the traditional way of painting.

   For some small and medium-sized manufacturers, the very beginning there is no need to frequently spend millions to buy the entire UV-ray. Because without the support of certain production, machinery and depreciation costs of energy consumption is very high, more harm than good. The best way to introduce a section of equipment, training workers, and master the equipment, skilled craft. The first phase with UV primer primer PU furniture to replace the inner panels and side panels; the second phase with UV paint to do with the board and the side of the primer and paint and primer are panels; the third phase to be enterprises developed to a certain size, have sufficient orders to consider the introduction of the whole line to replace the UV import PU, PE paint.

   The next few years, painting the most perfect combination of the way is through a complete line of UV to achieve, within the panel, side panels UV lacquer coating is UV coating panel primer, showering or spraying PU coated finish. Can significantly increase productivity, while maintaining good results. In some large-scale manufacturers several years ago began to use this way of painting, and has played a tremendous role.

   Early exposure to UV furniture factory paint, the use of UV paint, in order to keep pace with the development trends, to make our products more competitive in the market competition in an invincible position.
