MANUFACTURING METHOD OF SLURRY
To provide a manufacturing method of a slurry, capable of manufacturing a slurry which is homogeneous and properly thickened and can be efficiently transferred while causing less residue in pipings, etc., on transfer.SOLUTION: Disclosed herein is a manufacturing method of a slurry, for manufacturing a slurry by blending water, an inorganic powder, and an amine oxide-type surfactant ((A) component hereafter), wherein the manufacturing method of a slurry includes: performing blending of water and the inorganic powder by using a kneader including a rotation shaft, an agitation member provided in the rotation shaft, and a kneading tank under a condition that a peripheral speed of the maximum diameter part of the agitation member is 20 m/min or over and a Froude number of 0.40 or over in the kneading tank for 4 s or over to obtain a blended product; and performing addition of the (A) component to the blended product and blending by using a kneader including a rotation shaft and an agitation member provided in the rotation shaft under a condition that a peripheral speed of the maximum diameter part of the agitation member is 20 m/min or over and a Froude number is 0.4 or over for 8 s or over in the kneading tank.SELECTED DRAWING: None
【課題】均質で適度に増粘され、移送時の配管などへの残留が少なく効率よく移送できるスラリーを製造できる、スラリーの製造方法を提供する。【解決手段】水、無機粉体、及びアミンオキシド型界面活性剤〔以下、（Ａ）成分という〕を混合してスラリーを製造する、スラリーの製造方法であって、水と無機粉体とを、回転軸と該回転軸に設けられた撹拌部材と混練槽を含む混練装置を用いて、前記撹拌部材の最大径部分の周速度が２０ｍ／ｍｉｎ以上、且つフルード数が０．４０以上での条件で、前記混練槽内で４秒以上混合して混合物を得ること、及び前記混合物に（Ａ）成分を添加して、回転軸と該回転軸に設けられた撹拌部材とを含む混練装置を用いて、前記撹拌部材の最大径部分の周速度が２０ｍ／ｍｉｎ以上、且つフルード数が０．４以上での条件で、前記混練槽内で８秒以上混合すること、を行う、スラリーの製造方法。【選択図】なし
