Recently, in the Guangdong anti-corrosion wood market, the long-lasting anti-corrosion effect makes the anti-corrosion wood the most widely used in the outdoor garden field, and is deeply loved by consumers. However, "people are afraid of being famous, pigs are afraid of strong". With the widespread application of anti-corrosion wood, under the influence of interests, some unscrupulous merchants have to cut corners to reduce production costs, so that quality products are flooding the anti-corrosion wood market and affecting market consumption. Confidence makes the businesses and consumers who are law-abiding operators miserable.
"When you use preservatives, it is called anti-corrosion wood, and it is distributed to the market in large quantities. The price is as low as 2000-3000 yuan/m3. Because of the low price, many manufacturers and decoration companies are eagerly attracted, but this kind of cheap quality is inferior. Due to the rough processing technology, the anti-corrosion wood will have quality problems in 3 months, and the ultimate victim is the consumer.†When talking about the inferior anti-corrosion wood that is flooding the market, Mr. Luo, who has been dealing with wood preservatives for more than ten years, is particularly excited.
"High-quality anti-corrosion wood anti-corrosion anti-ant strong, can withstand the outdoor wind, sun, rain and 40 years of immortal long life, environmental protection and safety, and will not become black, not easy to deform." Mr. Luo said that anti-corrosion wood The characteristics are like a few treasures.
“The production process of high-quality anti-corrosion wood is more complicated. The anti-corrosion wood can withstand the long-lasting life of 40 years of outdoor wind and sun, and it is closely related to its processing process,†said Professor Chen Shaorong of South China Agricultural University.
“Firstly, the sawn wood is sent into a giant closed vacuum tank, first vacuumed for degreasing and dehydration; then heated and pressurized, the anti-corrosion agent is pressed into the interior of the wood by vacuum pressure, and the preservative penetrates into the cell tissue of the wood. Inside, it is tightly combined with wood fiber to achieve the purpose of anti-corrosion and pest control." Professor Chen said. “In order to allow preservatives to effectively enter the wood, the materials have also been specially screened. According to the comprehensive evaluation of foreign authorities, the most ideal outdoor landscape anti-corrosion materials are North American Jobb, American Southern Pine, North American Hem, Finnish Pine, North American twisted leaf. Pine, New Zealand radiata pine, Pinus sylvestris, Northeast pine, Burmese hemlock."
However, some domestic merchants are often driven by interests, reducing the amount of preservatives and simplifying the anti-corrosion processing. For example, the anti-corrosion wood substrate has a high content of turpentine. In order to increase the service life of the anti-corrosion wood, liposuction is extremely important in the processing of anti-corrosion wood. However, due to the pursuit of interests, the bad business often omits this process, but only uses anti-corrosion agents. Soaking it allows the wood to enter the circulation market and swindle consumers.
Mr. Luo, who manages the anti-corrosion wood, has calculated the account: “The normal dosage ratio of preservative is 6.5Kg/m3. The manufacturer reduces the cost, the proportion of preservative is diluted to 1Kg/m3, and the liposuction is reduced. In the process, the production cost of anti-corrosion wood can be reduced from 400 yuan / cubic meter to 50 yuan / cubic meter. Such a huge difference in profits is no wonder that many unscrupulous businesses will invade this trend. Manufacturers are earning pots. Full of consumerism, but the loss of consumers is big. Under normal circumstances, the use of high-quality anti-corrosion wood is up to 40 years, while the use of anti-corrosion wood for "cutting the work" is 2-3 years, the loss of consumers How big can you think about it!"
"Good quality and low price is the common desire of every consumer to purchase. However, it is not easy to do this in real life. The so-called is a penny, a piece of goods, and the goods are generally not cheap, and the purchase of anti-corrosion wood is also So," said Mr. Luo.
It is learned that the best substrate for wood preservative is North American hemlock, but because of the relatively high price of hemlock, the most commonly used wood preservative substrate for domestic anti-corrosion wood manufacturers is Russian scotch pine. Due to its high content of turpentine in the permafrost regions of the genus Pinus sylvestris, it requires a strict liposuction process. At present, the price of hemlock wood preservative in the Guangdong market is 5,500 yuan / cubic meter, and the pine wood anti-corrosion wood is 3,000 yuan / cubic meter.
Anti-corrosion wood purchase tips:
smell. Unqualified wood preservatives have a strong smell and are very pungent. There are no high-quality anti-corrosion woods, and some even emit pleasant aromas, such as Jomber's anti-corrosion wood.
Look. Unqualified wood color will be too bright and will be easily oxidized under ultraviolet light. The high-quality anti-corrosion wood is quaint and has good stability and is not easy to be oxidized.
