Description
薬剤で処理された植物系材料の物性の温度依存性とは、当該植物系材料の粘度が温度によってどのように変化するかの指標であり、例えば、熱機械測定、およびこれに準ずる測定方法によって求めることができる。
(1)植物成形体の製造装置について
図1の(a)には、本発明の植物成形体の製造方法を実施するための製造装置(成形機)1の構成を示す。図1の(a)に示す製造装置1は、主な構成部材として、パンチ11、材料投入部12、ヒータ設置部13、及び、金型14を備えている。
金型14は、材料投入部12から投入された植物系材料を所定の形状に成形するための凹部を有する金型である。図1の(b)は、金型14の平面図である。図1の(c)は、出口部分の側面図である。また、図2は、金型14の斜視図である。図1の(b)に示すように、本実施の形態では、金型14に設けられた凹部の平面形状は、杓子のような形状を有している。但し、これは本発明の一例であり、本発明はこれに限定はされない。
続いて、上述した製造装置1を使用して実施される植物成形体の製造方法について説明する。なお、ここで説明する植物成形体の製造方法は本発明の一例であり、本発明の植物成形体の製造方法は製造装置1を用いて実施するものに限定はされない。図3の(a)から図3の(c)、及び、図4の(a)から図4の(c)には、本発明の植物成形体の製造方法の一実施形態の各工程を示す。
さらにこのとき、金型14の各部分の寸法(図1の(b)および(c)参照)を、W1=52mm、W2=20mm、W3=10mm、H1=10mm、H2=5mm、形状固定部14cの長手方向の長さ=85mmとする。但し、この寸法は本発明の一実施例であり、本発明はこれに限定はされない。
続いて、本発明の植物成形体について説明する。本発明の植物成形体の一例としては、上述した製造装置1を用いて得られる植物成形体が挙げられる。
本発明の植物成形体は、上述のように、長尺な形状に形成することができるとともに、使用する金型の形状に応じてその断面形状を適宜変更することができる。そのため、本発明の植物成形体は、建材に好適に利用することが可能である。
