- 摘要：For this paper, the author studied and statistically analyzed the amount of wood-based panels used for building construction in America and in some European countries. He then analyzed the potential use of wood-based products, especially oriented strand board （OSB）, in the Chinese building industry by estimating the future annual demand of building materials. Finally, some suggestions were provided for expanding markets for China’s OSB industry.关键词：Oriented strand board （OSB）;Building system;Potential use

发布时间：2021-02-08 - 摘要：This paper is a review of a study the authors made on research that has been done on wood machining properties. The authors report the developments that have been made in this area as well as test methods and standards for evaluating wood machining properties worldwide. They have also analyzed the importance of studying wood machining properties for wood resource utilization, especially the wood from plantation grown forests. Since the testing and evaluation of wood machining properties are new subjects for the Chinese wood industry, some suggestions on conducting further investigations and establishing related national standards are given.关键词：Wood machining properties;Status of the research;Testing standards

Results showed that there are great differences in chemical composition between outer face and inner face of rice straw. For example, there are only a few active groups, like hydroxyls, on outer face of the straw with an oxygen/carbon （O/C） ratio as low as 0. 068 while more hydroxyl groups were on the inner face where the O/C ratio reached 0. 284. However, after thermal-mechanical treatment, more hydroxyl groups occurred on the straw fibers obtained by thermal-mechanical treatment and the O/C ratio increased greatly. The results indicated that thermal-mechanical treatment can improve interface bonding efficiency between straw and adhesives. It provides evidence for further study on manufacturing straw-based MDF with UF resin.关键词：Rice straw;Thermal-mechanical treatment;Surface characteristics;Infrared spec- troscopy;X-ray photoelectron spectroscopy

发布时间：2021-02-08 - 摘要：In order to solve technological problems when urea-formaldehyde （UF） or phenol formaldehyde （PF） resin was used as an adhesive for faced plywood, the author conducted a series of experiments on a modified PF resin by adding melamine urea-formaldehyde （MUF） resin. Then he analyzed the effects of molar ratio of PF and MUF resin, mixture proportion, and hot pressing conditions on viscosity and durability of the modified resin, surface veneer color and bonding performance of the board, and provided the optimum technology parameters for the application of PF resin. Furthermore, the MUF modified PF resin was used to manufacture multi-layer parquet and test results showed the physical and mechanical properties of the parquet could meet demands of the National Standard GB 9846.1-12-88.关键词：phenol formaldehyde resin;Melamine urea-formaldehyde resin（MUF）;modification;plywood

发布时间：2021-02-08 - 摘要：A numerical simulation model based on finite element analysis was established in this article to determine the temperature distribution in wood during an insecticidal heating treatment. The calculated temperature was compared with that measured from a typical operation and shows the feasibility of applying finite element analysis to predict the thermal response of wood. On the basis of the results, further experiments were conducted to analyze the effects on the shape of wood sections, the temperature elevation rate and heat preservation value as a result of the thermal response of wood. The calculated results provide a theoretical reference for designing a monitoring system and operating process for insecticidal treatment of wood.关键词：finite element method;Numerical simulation;temperature;wood;heat treatment

发布时间：2021-02-08 - 摘要：Small-scale MDF manufactures with annual output of less than 30 thousand m3 have accounted for 77% of the total MDF manufacturers in China with many of the production lines having been in operation for many years. Many of these lines are now running at low productivity with high raw material costs and high energy consumption coupled with ageing equipment and buildings. Based on the economic condition of these manufacturing companies, the authors explained the necessity of technical improvements in these small companies and provided suggestions about the key technical measures that should be made. Experience has shown that modernizing equipment and technologies is an efficient and effective way for these manufacturers to gain further development.关键词：Medium density fiberboard （MDF）;Enterprises;Technical innovation

发布时间：2021-02-08 - 摘要：Abstract: This paper focused on the pollution problems in the wood-based panels industry in China. From the point of economics, it analyzed the causes of negative external economic activities from wood-based panel factories and pointed out the importance of controlling pollution through government regulation. In the end, it proposed some suggestions on controlling pollution such as setting up related national standards and strict monitoring by the state, adopting appropriate environmental protection laws and governmental subsidy in order to encourage factories to apply advanced techniques and technologies to minimize emissions that cause pollution.关键词：Wood-based panels industry;Pollution;Control;Economic analysis

发布时间：2021-02-08 - 摘要：An energy plant is a new kind of heat supply system for the wood-based panel industry characterized by using wood residues as fuel. Compared with a traditional steam boiler, the author made a calculation on the environmental protecting indexes of an energy plant. The results revealed the superiority of an energy plant in environmental protection, energy and cost saving over the steam boiler. Also, the author reviewed the prospect of the development of an energy plant used in the forest products industry in China.关键词：Energy plant;Indexes on environment protection;application
