Concerning a mechanism for removing clay particles of washing liquids from pores

Abstract

Examined is a mechanism for removing the clay particles of washing liquids from a pore space. All the experiments are conducted in 1-% clay, water and polymer solutions (with a viscosity of 120 in accordance with SPV-5), made of clay powder of the Makharadz'ye deposit with a particle size of 40-60 mkm, sorted by a screen method. The polymer solutions were made on the basis of hypane, metas, polyacrylamide, KMTs-500, KhS-1 biopolymer, modified and clusterized by an alkaline (NaOH) of cornstarch. Studied is the process of removal of the solid phase from an ''ideal pore'', that is, a quartz capillary. It is demonstrated that the break away of the basic mass of the bentonite particles sedimented from the washing liquids on the quartz surface from the capillary and the formation by them of ''suspended flocules'' occurs at a water current speed in the pore equal to 2.5-4.0 times 10/sup -3/m/s. The carry away of the particles sedimented from the polymer solutions of metase, hypane, clusterized and modified starch, KMTs-500 and water occurs at a stream speed above 5.4 times 10/sup -3/m/s. The greatest speeds are required for the removal of clay particles more than 15 mkm in size from the  More>>
