AN2000型高效减水剂属既非萘系又非氨基磺酸系的新剂型，是采用煤焦油中的稠环芳烃为原料，制得稠环芳烃甲醛缩合物，作为减水剂，保证混凝土质量和效能均有明显提高。
AN2000 type superplasticizer is not a new type of naphthalene-based or non-aminosulfonic acid-based system. Polycyclic aromatic hydrocarbons in coal tar are used as raw materials to produce condensed-ring aromatic condensates of formaldehyde as a water-reducing agent to ensure concrete quality. Both efficiency and effectiveness have been significantly improved.
