研究了一系列分子量不同的丙烯酰胺与N,N-二甲基二烯丙基氯化铵的链节比为9:1的共聚物(PAMDA-10)在硅藻土加填桉木纸浆中的助滤助留性能。试验结果表明:PAMDA-10152对桉木浆0.3%添加时,可使该浆料的打浆度从44.0°SR下降到29.0°SR,白水浊度从9.52NTU降低到4.90NTU;PAMDA-10152对硅藻土加填纸浆0.5%添加时,可使该浆料的打浆度从57.5°SR降低到36.5°SR,白水浊度从56.70NTU降低到14.02NTU,硅藻土的留着率达到97.31%。
A series of copolymers (PAMDA-10) with different molecular weight ratios of acrylamide to N, N-dimethyl diallylammonium chloride in a ratio of 9: 1 were studied in diatomaceous earth plus eucalyptus pulp Filter aid retention performance. The results showed that when PAMDA-10152 added 0.3% of eucalyptus pulp, the beating degree of PAMDA-10152 decreased from 44.0 ° SR to 29.0 ° SR, and the turbidity of white water decreased from 9.52 NTU to 4.90 NTU. PAMDA- The addition of 0.5% Alkaline Soil Pulp increased the beating degree of the slurry from 57.5 ° SR to 36.5 ° SR, the white water turbidity decreased from 56.70 NTU to 14.02 NTU, and the retention rate of diatomite reached 97.31%.
