コストがかさむという問題があった。As mentioned above, when two or more types of liquids, in which the main agent and curing agent are separately pumped by respective metering pumps, are introduced into the mixer and mixed and stirred, it is necessary to ensure sufficient and reliable mixing. Conventionally, the processing is complicated, such as planting a large number of bottles perpendicular to the mixer shaft, or forming stirring blades by cutting out using a milling machine, etc.
There was a problem that the cost was high.
また、従来の攪拌翼の方式では、剪断ミキシングである
ため、剪断熱が液中に発生し、液に悪影響を与えると共
