TL;DR: Thermodynamic studies revealed that the adsorption processes is spontaneous and endothermic in nature and DCB has potentials for application as adsorbent for the removal of MG from dyeing process wastewater.
TL;DR: In this article, the nano-sized SiO2 particles have been used to enhance the bond strength of the UFG sheet materials in the cumulative roll bonding (ARB) process, which is one of the most promising methods for industrial production of ultrafine grained (UFG) sheet materials.
TL;DR: In this article, stable, aqueous cleaner/degreaser emulsion compositions are formulated with at least one sparingly soluble organic solvent having specified compositional characteristics, a solubilizing additive and water.
Abstract: Stable, aqueous cleaner/degreaser emulsion compositions are formulated with at least one sparingly soluble organic solvent having specified compositional characteristics, a solubilizing additive and water. The solubilizing additive may consist of from approximately 0.1 to approximately 100 weight percent of a surfactant and from 0 to approximately 99.9 weight percent of a coupler and is present in an amount insufficient to solubilize all of the total organic solvent content but sufficient to emulsify the unsolubilized portion of the total organic solvent content. The emulsion compositions so formulated provide enhanced degreasing efficacies.
TL;DR: In this paper, an environmentally-friendly cleaner comprising the amide or the hydramine, a composite surfactant and the like removes grease under the alkalescent condition, and has good cleaning effect due to the permeation effect of the composite materials on the grease and an oxide layer.
Abstract: The invention belongs to the field of surface treatment, and relates to a stainless steel cleaner. The cleaner comprises a nonionic surfactant, an anionic surfactant, a complexing agent, a degreasing agent and deionized water, wherein the degreasing agent is one of amide, and a mixture of amide and hydramine. An environmentally-friendly cleaner comprising the amide or the hydramine, a composite surfactant and the like removes grease under the alkalescent condition, and has good cleaning effect due to the permeation effect of the composite surfactant on the grease and an oxide layer. The invention also relates to a stainless steel cleaning method. The stainless steel cleaner and the stainless steel cleaning method are widely applied to the treatment of various stainless steel surfaces.
TL;DR: In this paper, the feasibility of using an ultrafiltration membrane and ozone treatment to reuse oily wastewater generated from the automobile-components manufacturing industry was investigated, and the UF membrane system (capacity, 5 t/d) was employed to treat two kinds of degreasing wastewater and cutting oil wastewater.
