Abstract

To solve the issue of dust pollution generated during building construction, in the work, using oxidized corn starch (OCS) as base material, acrylic acid (AA) as monomer, and flaxseed gum (FSG) and glycerin (GLY) as modifiers, FSG modification OCS-graft-polyacrylic acid (PAA) composite (OCS-g-PAA/FSG/GLY) as liquid dust suppressant was fabricated by grafting polymerization and hydrogen bonding. The optimum reaction conditions for OCS-g-PAA/FSG/GLY were determined by single factor experiment. The performance test results of OCS-g-PAA/FSG/GLY show that the dust specimens treated with OCS-g-PAA/FSG/GLY could retain water for 12 h at 60 °C, the average hardness of the consolidation layer on the surface of the dust specimen reached 71.4 HA, at a wind speed of 12 m/s, the dust specimen loss rate was only 1.96 %, and the resistance to water corrosion could reach 96.82 %, which is expected to be used for dust control in the field of building construction.

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
