Formaldehyde pollution is really annoying. No, Beijing resident Zhang Lei and his couple have just moved into their new homes, added new furniture, and prepared to have children. It can be heard that some homes have formaldehyde pollution, which will affect pregnant women and children. Therefore, the "baby project" has been afraid to start.
There is a saying that after opening the window for a few months, the odor is gone, and the formaldehyde content of the furniture will be greatly reduced. But according to industry experts, it takes 15 years for formaldehyde to completely dissipate.
At present, most of the furniture on the market in China is made of artificial wood plates, and the bottom glue is mostly made of formaldehyde-containing glues such as uraldehyde resin and phenol resin. The key to pollution lies in the glue. Can we find a new type of glue that does not contain formaldehyde and can meet the performance requirements of the board?
This research project was included in the national research plan. After hard work, an adhesive that meets the above requirements-isohydrocarbonate was developed. This kind of ecological and environmental protection adhesive with China's independent intellectual property rights was jointly developed by the Chinese Academy of Forestry, Nanjing Forestry University and Wanhua Ecological Board Co., Ltd., but the price per ton is as high as 20,000 yuan, while the traditional formaldehyde-containing adhesive Only 1,000 yuan per ton.
With such a high price, how to get a good reputation in the market? Just playing the "environmental protection and ecological brand" is not only not recognized by man-made plate manufacturers, but also not accepted by ordinary consumers. Can we find a way to reduce plate costs?
The researchers found that developed countries such as Europe and the United States used cheaper crop straws to replace wood, which greatly reduced the total cost of the board. So, they tried to use rice, wheat, reed, rape and other crop straws as raw materials. After repeated experiments, this new type of ecological straw board finally succeeded.
"Foreign ecological straw plates can only use one kind of straw, but our country can use a variety of straws." Yu Wenjie, general manager of Wanhua Company, said that for the storage and transportation of straws by land, the utilization rate of the production line is improved Enhancing production and management efficiency has great advantages.
This kind of straw ecological board is only 200-300 yuan more per cubic meter than traditional wood board. However, at the beginning, the market recognition was still not high enough. Only in Beijing, Shanghai, Guangzhou, Wuhan and other big cities, the sales were better. Where did the problem lie?
The survey found that people originally worried that the straw board was not strong, and the consumption concept could not be turned for a while. "In fact, after being tested by the national authority, this straw board meets the standard in more than ten strength indicators, which is harder than wood board, and it is no problem to screw or soak water." Yu Wenjie said that environmental protection products are a kind of New products with high-tech concentration require efforts to reduce costs and increase publicity, and need the support of the whole society. Today, people are gradually accepting this product.
It is understood that the current market capacity of China's artificial board has reached 100 million cubic meters, and the market potential of straw ecological board has hundreds of billions of yuan. Yu Wenjie believes that straw ecological sheet belongs to the environmental protection industry. "The environmental protection industry has a certain public interest, and full market promotion is not impossible, but it is not the best way." Yu Wenjie said that a straw sheet enterprise can solve the pollution problem of crop straw burning in the surrounding 50 kilometers; The purchase price per ton of straw is about 300 yuan, which can also increase the income of hundreds of thousands of farmers and has great environmental, economic and social benefits. "The government should give more support in policy, give preferential treatment in finance and taxation, carry out strategic layout in the manner of a large industry, and vigorously promote it in a systematic and large-scale manner."
