Abstract: PURPOSE: An electrically reformed fluid is provided to impart unique features of Newtonian fluid at non-load state of electric field whereas flow control ability at load state of the field by comprising dried water-soluble starch as the conductive particulate. CONSTITUTION: The reformed fluid is prepared by grinding the water-soluble material(103) into less than 10 micrometer size particles by means of grinder(141); drying the particles in a constant-temperature and humidity device(142) under a condition of 35-45 deg.C and 30-50% of relative humidity; blending the dried material with a non-conductive solvent(102) selected from silicon oil, transformer oil, transformer insulating solution, mineral oil or olive oil alone and/or in combination with two of them in a weight ratio of 5-70wt.% based on the solvent in a container(143); heating the obtained fluid in an oil bath(144) of 100-150 deg.C; alternatively grinding the prepared electrical reformed fluid regularly miscible together in another grinder(145); and introducing the fluid(101) into a bottle(146). The reformed fluid has 5wt.% or less of water content.

Abstract translation: 目的：提供一种电子改性流体，以通过包含干燥的水溶性淀粉作为导电颗粒，在非负载状态下赋予牛顿流体独特的特征，而在场的负载状态下的流动控制能力。 构成：通过研磨机（141）将水溶性材料（103）研磨成小于10微米尺寸的颗粒来制备改性流体; 在35-45摄氏度和30-50％相对湿度的条件下，在恒温恒湿装置（142）中干燥颗粒; 将干燥的材料与单独的硅油，变压器油，变压器绝缘溶液，矿物油或橄榄油中的非导电溶剂（102）和/或其中的两种以5-70重量％的重量比混合， 基于容器（143）中的溶剂; 在100-150℃的油浴（144）中加热得到的流体; 或者研磨在另一研磨机（145）中定期混溶在一起的制备的电改性流体; 并将流体（101）引入瓶（146）中。 重整液的含水量为5重量％以下。
