Description
次に、Ｍｅｌｔ ＥＳＤ方式を使用した紛体化の方法について、図２に基づいて説明する。
まず、粘土が十分下がるまで加熱して溶融された熱可塑性ポリマーをシリンダー１の先端に供給する。次に、供給された溶融ポリマーはノズル２から吐出する。この際、同時にエアー導通路４に供給された高温の高速エアーがエアーノズル５から噴出される。この噴出した高速エアーは、ノズル２上で衝突し圧縮され高圧となる。そして、この噴出した高温の高圧縮エアーにより生じる気圧差により溶融ポリマーは紛体化される。Next, a powdering method using the Melt ESD method will be described with reference to FIG.
First, a thermoplastic polymer melted by heating until the clay is sufficiently lowered is supplied to the tip of the cylinder 1. Next, the supplied molten polymer is discharged from the nozzle 2. At this time, high-temperature high-speed air supplied to the air conduction path 4 is ejected from the air nozzle 5 at the same time. The jetted high-speed air collides on the nozzle 2 and is compressed to a high pressure. The molten polymer is powdered by the pressure difference generated by the jetted high-temperature high-compression air.
Ｍｅｌｔ ＥＳＤ方式で異種ポリマーをペレット状態で混合すると、異種ポリマーは互いに混ざり合わないため、独立した状態で紛体となる。これによって、異種ポリマーが紛体状態で分散状態となる。その結果、各ポリマーの特性を併せ持つ状態となる。 When different types of polymers are mixed in the pellet state by the melt ESD method, the different types of polymers do not mix with each other, so that they become powder in an independent state. As a result, the dissimilar polymer is dispersed in the powder state. As a result, the polymer has the characteristics of each polymer.
