摘要
Abstract
Using CO2 as solvent and polyethylene wax as solute, the polyethylene wax microparticles were prepared using rapid expansion of supercritical solutions (RESS) method. The influences of pre-expansion temperature, pre-expansion pressure and collecting distance on the average size of formed fine particles were discussed. It was found that smaller average diameter of fine particles could favorably be obtained under higher pre-expansion pressure and higher pre-expansion temperature. Within the collection distance of 50 mm, the particle size increased with the increase of the collection distance. When the collection distance was more than 50 mm, the particle size did not increase.关键词
