Detergency of Silica Particle Soil by Water/Ethanol Mixture Solution

Abstract

In detergency, organic solvents have a broad range of applications. Tetrachloroethylene, 1, 1, 1-trichloroethane and petrorium solvent are used in the textile industry and CFC in electronics. But their use is attended with environmental pollution and stricter regulations are called for. The detergency of silica particle soil, a main component of dust, was examined using water/ethanol mixture as an alternative solvent. Stainless and polyethylene meshes were used as substrates each with a different surface energy. The nonionic surfactant, C18H37O (CH2CH2O) 8H, organic alkaline builder, (CH3CH2 (C2H5) N+) OH-, and inorganic builder, Na2SiO3, were used at different ratio of water to ethanol ratios in solution. Detergency was always large on using water 100% or ethanol 100% as solvents and detergency was minimal for the water/ethanol solution. The detergency of polyethylene exceeded that of the stainless mesh in most cases and the latter was affected by builder component rather than surfactant. Polyethylene was affected by both surfactant and builder components.
