    摘要: This invention relates to compositions and methods for treating subterranean formations, in particular, oilfield stimulation compositions and methods using water-in-water polymer emulsions to uniformly dissolve a rheologically active polymer, such as a thickener or friction reducer, in the treatment fluid. The emulsions have a low viscosity and are easily pumped for mixing into a treatment fluid, where upon dilution with an aqueous medium, the polymer is easily hydrated without forming fish-eyes. The partitioning agent in the water-in-water emulsion does not generally affect the rheology of the treatment fluid. The invention also relates to further processing of the emulsion by wet grinding, high shear mixing and/or heating to enhance the hydration rate in the preparation of the well treatment fluid.

    摘要: Paunch-sludge from an abattoir is mixed with the fatty DAF-float from an abattoir, and placed in a shearing vessel. The mixture of the two material thickens the medium in which the matted strands are contained, enabling shearing to be more effective; so much so that paunch-sludge can now be sheared to a homogeneous liquid. The technique can be used with other sludges and other fatty waste materials.

    摘要: The invention is a method for producing a mixture of powder or granular state material and liquid, in the course of which a first mixture is produced by conveying the powder or granular state material through an inlet hopper into an upper mixing space and by feeding the liquid into the upper mixing space, the first mixture is introduced into a lower mixing space through a conducting pipe connecting a bottom part of the upper mixing space and an upper part of a lower mixing space having a cylindrical space portion and a conical space portion, and a second mixture is produced by causing it to collide into a baffle member, the second mixture is discharged through the conical space portion arranged at the bottom part of the lower mixing space. By dividing the second mixture, a first mixture portion is discharged as a mixture material, a second mixture portion is re-circulated into the upper mixing space, and a third mixture portion is conveyed into the upper part of the lower mixing space. The ratio of the first mixture portion to the second mixture portion is chosen to a value between 1:1 and 1:4, the ratio of the first mixture portion to the third mixture portion is chosen to a value between 1:1 and 1:5, and in the lower mixing space the amount of the second mixture is adjusted so that the surface of the second mixture is within the cylindrical space portion of the lower mixing space and is spaced from the baffle member.

    摘要: The invention discloses an environmentally-friendly pasty discharge agent for textile printing and a method for preparing the environmentally-friendly pasty discharge agent. The environmentally-friendly pasty discharge agent for textile printing is formed by the following raw materials according to part by weight: decamethylcyclopentasiloxane: 30-60 parts; thiourea dioxide: 40-70 parts; surfactant: 1-3 parts; and glycerol: 3-6 parts. Decamethylcyclopentasiloxane is put into a ball mill, a surfactant is added into the ball mill to make the decamethylcyclopentasiloxane dispersed or dissolved uniformly and then stirred uniformly, and then thiourea dioxide is added into the ball mill and ground together for 1-3 hours. In the invention, the special liquid compound decamethylcyclopentasiloxane does not chemically react with the thiourea dioxide; in addition, it isolates the thiourea dioxide from outside water and air, thus increasing the stability of the thiourea dioxide. The discharge effect is excellent, the defects of low dissolvability, poor dispersion uniformity in the discharge paste, poor net permeability and insufficient discharge effect of the common thiourea dioxide as the discharge agent are overcome, and there is no influence on the touch of the discharged and printed textiles.
