以三硬脂酸甘油脂、聚乙二醇、二乙醇胺为原料,制备一系列表面活性剂,合适反应条件为140℃,2h。参考HLB值,通过复配制成固体脱墨剂,所得产品具有良好自乳化性,在配方为W(尿素)=3%,W(NaSiO3)=3%,W(脱墨剂)=0.3%,W(Na2SO4)=1%,W(表面活性剂)=0.4%时,取得较好脱墨效果。通过扫描电镜观察,对回收纤维表面的油墨及其它杂质颗粒具有良好的剥离清洗作用。
A series of surfactants were prepared from tristearin, polyethylene glycol and diethanolamine. The suitable reaction conditions were 140 ℃ and 2h. With reference to the HLB value, the solid deinking agent was compounded to obtain the product with good self-emulsifying property. When the formulation was W (urea) = 3%, W (NaSiO3) = 3%, W W (Na2SO4) = 1%, W (surfactant) = 0.4%, get a better deinking effect. Scanning electron microscopy, the recovery of fiber surface ink and other impurities particles have a good stripping cleaning effect.
