| Abstract: |
| 【Objective】 The study investigated the best process of cotton stalk scrimber.【Method】 This paper presented the effect of manufacturing parameters,namely density,glue consumption,temperature and hot-pressing time on scrimber's mechanical performance by means of orthogonal experiments.【Result】 Results showed that the scrimber had the best mechanical performance when the parameters were as follows:density 0.6 g/cm3,glue consumption 120 g/kg,hot-pressing temperature 140 ℃ and hot-pressing time 10 min.【Conclusion】 It is reliable to use urea-formaldehyde resin to manufacture cotton stalk scrimber,and the density has direct influence on scrimber performance. |
