Abstract
The biomass based deinking agent was prepared by using cheap and renewable coconut fatty acid,palmitic acid and gum rosin as raw materials.The raw materials were characterized by FT-IR;the technology of preparation was optimized;the optimum addition amount of deinking agent and the deinking properties were discussed.The deinking properties were also compared with the traditional deinking agents.The FT-IR results showed that the raw materials were both saturated fatty acids and unsaturated fatty acids,and the optimized preparation conditions of biomass deinking agent were 30min,90℃,m(gum rosin)∶m(coconut fatty acid)∶m(palmitic acid) of 2.5∶3.5∶4.0,NaOH mass fraction of 40%.The obtained biomass based deinking agent was a kind of high efficient deinking agent,and the optimum addition amount was 0.2%.After deinking under the addition amount 0.2%,40℃,the mass fraction of pulp 1.0% and pH value 9 for 20min,the brightness of deinking pulp was 58.67%(ISO),the residual ink concentration was 274.42mm2/m2,and the removal rate of ink was 57.81%.Practical application results showed that the deinking effect of biomass based deinking was superior to that of the traditional type S and tian xiao deinking agents.关键词
