溶解浆属于高纯度的精制浆,主要用于生产黏胶人造丝、硝化纤维、醋酸纤维、玻璃纸、甲基纤维素等产品。据统计,2008年全球对溶解浆的需求量为420万t,预计到2025年全球溶解浆需求量将达到650万t,其大部分用量在中国。目前,国内溶解浆的产能大都在5万t以下,生产规模不大,都存在经济效益差、产品质量不稳定等问题。 Dissolving pulp is high purity refined pulp, mainly for the production of viscose rayon, nitrocellulose, acetate, cellophane, methyl cellulose and other products. According to statistics, in 2008, the global demand for dissolving pulp is 4.2 million tons. It is estimated that the global dissolving pulp demand will reach 6.5 million tons by 2025, most of which is in China. At present, most domestic dissolving pulp production capacity is less than 50,000 tons, the production scale is not large, and there are problems such as poor economic benefits and unstable product quality.
