纯碱行业供需及反内卷更新 20260227 摘要 纯碱生产工艺主要分为氨碱法、联碱法和天然碱法，其中天然碱法成本 最低，约为 600 元/吨，氨碱法成本约 1,300 元/吨，联碱法考虑副产品 氯化铵后成本约 1,000-1,100 元/吨。企业会根据轻重碱价差调整生产 结构，价差缩小时倾向于生产轻碱以降低成本。 国内纯碱产能结构正在发生变化，天然碱占比显著提升，从 2023 年的 6%提升至 2025 年的百分之十几，氨碱法占比下降，联碱法占比提升。 政策上，氨碱法因环保问题受限，天然碱法受支持，联碱法未见明显限 制。 2026 年纯碱新增产能投放节奏预计放缓，产量增量主要来自 2025 年 已投放装置的爬坡达产，如湖北和博源集团的天然碱项目。2027 年下 半年通辽项目一期 500 万吨产能预计投产。 国内纯碱行业集中度高，头部企业产能占比约 74%，主要集中在华北、 华中和西北区域。博源集团和河南金山是主要生产商，产能分别为 660 万吨（预计 2026 年达 780 万吨）和 640 万吨（新增后将超 800 万 吨）。 Q&A 纯碱产品结构中，轻质纯碱与重质纯碱的核心差异是什么？两者价差通常如何 形 ...

The commissioning of the second line at Alashan is expected to further enhance supply [3]. Group 3: Institutional Insights - According to Caixin Futures, soda ash demand is being negatively impacted by a decline in float glass production, with short-term growth in demand expected to be negative. However, demand for light soda ash may increase due to the expansion of lithium carbonate production and improved exports [5]. - The overall production capacity of soda ash is projected to reach 44.6 million tons by 2026, influenced by significant new capacity additions. This high capacity may lead to a production strategy focused on "production as needed," putting pressure on cost lines for ammonia soda production [5]. - Zhengxin Futures suggests that short-term fluctuations in soda ash prices are primarily driven by commodity sentiment, with limited changes in the fundamentals. The market outlook remains cautious, with a focus on potential rebounds in glass production [5].
