Since 2005, the prices of various mahogany raw materials have risen to varying degrees. The scarce raw materials such as red leaf sandalwood and Vietnam Huanghua pear rose from hundreds of thousands to one million per ton. By 2007, the best Hainan Huanghua pears had reached the point of bargaining by the catty. Since 2008, mahogany raw material prices have remained stable for several years. However, since February this year, the price increase of Dalbergia altissima (commonly known as Dahong rosewood) began to show. Until June this year, the price of Dalbergia altissima has increased by more than 50% compared with the beginning of the year. A few years ago, Huang Huali's "one tree is hard to find" situation.
So, why does this red rosewood have a big shock? As far as red rosewood itself is concerned, it is just a kind of wood raw material with a very long growth period. From the mid-Qing period to the Republic of China period, the Chinese people have already harvested and purchased large-scale tropical rainforests from Southeast Asian countries. Today, the stock of original trees remaining in the tropical rainforests is very small. Before this, when the mahogany merchants preached the preciousness and scarcity of red rosewood, people faced the streets of mahogany furniture stores and dazzling red rosewood furniture, so the scarcity of materials is not very deep. When the Convention on International Trade in Endangered Species of Wild Fauna and Flora (hereinafter referred to as the CITES Convention) is formally implemented, both merchants and buyers only realize its value and scarcity. However, the promulgation and implementation of the CITES Convention only became the cause of the explosion of red rosewood raw materials and furniture, or fuse.
Throughout the progress of the entire mahogany industry, the author believes that the surge of red rosewood raw materials is actually a higher self-value realization of red rosewood furniture in its home use value, historical inheritance aesthetic value, and collection and circulation value. The deep-seated reasons behind several layers have prompted the price of red rosewood to keep rising and reached a peak this summer.
One of the reasons prices: red wood furniture household use value <br> <br> in mid Qing Dynasty ago, Chinese hardwood furniture is rosewood and pear mainstream, these two valuable timber had no price in history The Philippines, in terms of system, is not a royal or general prince. After the mid-Qing period, with the lack of these two types of wood, the old mahogany (red rosewood) appeared in front of the Chinese as an extension of red sandalwood. To be more precise, old mahogany has become a substitute for red sandalwood, its number is much larger than that of red sandalwood, and it is not subject to institutional restrictions, and the price can be accepted by the middle class, so as a carrier of fashion and fashion, red rosewood From the royal aesthetic of the palace to the middle class, it became a symbol of the middle class in that era to show wealth, aesthetics and taste of life.
After the mid-Qing period, artisans and the Chinese were known to have three kinds of Dalbergia wood, such as black rosewood, white rosewood and red rosewood. However, almost all the furniture uses red rosewood, which should be the texture, texture and color of red rosewood Closer to red sandalwood. Its red sandalwood-like color and texture make the furniture more in line with the orthodox and ethical aesthetic and festive taste of that era.
Today, as a part of modern home decoration, classical furniture has entered many ordinary people's homes. Whether one or two pieces of classical furniture are placed in the living room, bedroom or study, it can not only add highlights to home decoration, not only add classical and nostalgic elements to modern fashion colors, but also highlight the owner's fashion and classic aesthetic taste and life interest.
The second reason for the rise: the historical inheritance and aesthetic value of red rosewood furniture The aesthetic and cultural heritage. The full shape, hard texture, and beautiful texture of red rosewood furniture, in line with the aesthetic value of the crimson red color of the Orientals, and the high price, can also make modern home owners like the middle class after the middle and late Qing Dynasty Demonstrate their substantial wealth and high-end taste.
Classical furniture can also be said to be a microcosm of ancient Chinese wooden architecture. Its rigorous tenon-and-mortise structure, smooth lines and patterns give a solemn and subtle sense, revealing a peaceful and elegant Oriental Confucian style. People can live in modern homes. Like in China, enjoy the essence of Chinese traditional ancient architecture and the beauty of nostalgia at any time. If the Ming-style furniture is placed in the study room, the freshness and simplicity of the Ming-style can create a refined and elegant literati atmosphere like the bureaucrats in the late Ming Dynasty; placing the Qing-style furniture in the living room, the richness and complexity of the Qing-style furniture can also be created An atmosphere of wealth and luxury in the heyday.
The third reason for the rise: the collection and circulation value of red rosewood furniture
In addition to home use value and historical heritage aesthetic value, the price of red rosewood furniture is also affordable by the middle class. The middle-to-high-end middle class will consider Huanghuali furniture and rosewood furniture. In the current downturn in the stock market and the housing market, and the lack of investment channels, the middle-to-low-end middle class are showing their wealth and taste by purchasing red rosewood furniture. It is more fancy to the scarcity of raw materials of red rosewood furniture and the circulation and collection value of the deep processing technology and art according to traditional craftsmanship. The investment amount of red rosewood furniture is quite flexible. It can be large or small according to its own financial resources. It can be started with 50,000 yuan. The risk is small, and it is also a good choice for value preservation and appreciation.
With the introduction of the CITES Convention, red rosewood distributors have stirred up a price war that changes every day. At the same time, consumers are also aware of the collectivity of the red rosewood furniture's circulation value, accepting and willing to use more than ever Buying red rosewood furniture at a higher price is the traditional buying principle of "buy high but not low". When the double force is generated, it is normal for the red rosewood furniture to increase significantly, and it is possible to continue the legend of Huanghuali.
Washed suspensions of Escherichia coli were exposed to different concentrations of chlorine dioxide at various temperatures. Platings of the mixtures to evaluate the numbers of surviving cells were made after 5–300 sec of contact. Survival data were best fitted by a reaction model that is first order with respect to cell concentration and to exposure time. Bactericidal rates were found to increase markedly with both increased disinfectant concentrations and increased temperatures. Activation energies at each concentration of chlorine dioxide are reported.
