The strong base anion exchange resin provided by Suzhou Bojie Resin Technology Co., Ltd. can effectively reduce the acidity of nitrocellulose and achieve the expected deacidification effect, reducing the acidity to about 0.015%. The treatment time should be above 4h, and the mass ratio of resin to nitrocellulose is higher than 10:1. The resin has high mechanical strength, high osmosis rate, abrasion resistance, acid and alkali resistance, simple desorption and regeneration, long service life, and is suitable for large-scale industrial application.
