Studies On Experiment Of Process Characteristic Of Mix-material Flakeboard

In the modern world, the forest is decreasing and the use timber is increasing. China is a country that has numerous people and short of forest. Therefore, manufacturing flake board with cornstalk and beanstalk is an effective approach which is settle timber material crisis for the moment.Crop-stalk go by the name of forest resource secondly in the world, it is a vital substitute for the industry of false-board. China is an agricultural country which is abundant in stalk resource. According to statistics: china gives birth to kinds of crop-stalk seven hundred million ton every year and are 20-30 percent of stalk gross in the world. Stalk is about 5.66 hundred million ton except for return farmland and collection loss. If we produce flakeboard that use 20 percent of stalk, it will gain a hundred million false-boards which is twice times nearly the gross yield of world. The false-board with cornstalk and beanstalk not only settle environment pollution problem but also alleviate contradiction that feed and demand timber. It will increase income of farmer and bring good social benefit, economical benefit and zoology benefit.China has carry through much research to remainder characteristic and technical condition and economical feasibility of non-woodiness false-board with haulm and wheatstalk. But the studies on technology of stalk-board with cornstalk are less than others and not succeed production or application for the moment. The test refer about twenty years a lot of literature of wheatstalk and haulmstalk and manufacture false-board with cornstalk and beanstalk. The experiment carries through feasibility analysis to the technology. The text introduces experimental equipment and experimental material preparation. The experiment makes use of ANSYS software put up steady state heating analysis to the heating plate and improves the precision of experimental equipment.The study manufacture the stalk-board that content to national standard use cornstalk and beanstalk for material. According to characteristic of cornstalk and beanstalk, we use it through a series of process such as crush, wind choose, filter and mixture. The experimental glue adopt tannin resin that low-lying dissociative formaldehyde and non-pollution. The experiment combines flakeboard process technics and analyze the physical mechanics capability such as enactment density, the quantity of tannin resin, hot-pressing temperature, the hot-pressing pressure, the hot-pressing time, parting shape and the water rate of parting etc. Finally making sure the primary factors are the density, the quantity of tannin resin, hot-pressing temperature and the hot-pressing pressure. The experiment carries through capability...
