摘　　要：木聚糖酶或纤维素酶脱墨与化学脱墨相比,当木聚糖酶或纤维素酶用量在1IU/g时,就能达:到相同的脱墨效果。酶脱墨还能改善浆料的滤水性和强度,降低返黄程度。研究表明,纤维:素酶脱墨效果稍优于木聚糖酶,但当用量超过1IU/g后,对浆料强度损伤加剧。Both enzymatic and chemical deinking can obtain the same deinking effects at the enzymatic dosage of 1IU/g.Drainability, strength and postcolor of wastepaper pulp are improved by enzymatic deinking. The research results indicatethat the deinking effect of cellulase is better than that of xylanase. But the strength of pulp obviously decreases whenenzymatic dosage excesses 1IU/g.
