Nitrocellulose deacidification resin

Nitrocellulose is an important chemical raw material and is often used in the production of explosives, inks, coatings, cosmetics, etc. However, due to the hollow structure of cotton fiber, there is residual acid in it, which can catalyze the decomposition and deterioration of nitrocellulose. As a coating, nitrocellulose has high whiteness, and the presence of acid will turn yellow. In severe cases, it will be decomposed. It is hot and spontaneous. The ion exchange resin can be used to reduce the acidity of the nitrocellulose by the principle of ion exchange.
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.
