一种生物质水煤浆的表面添加剂及其应用方法
摘要：
本发明属于水煤浆技术领域，尤其涉及一种生物质水煤浆的表面添加剂及其应用方法，具体是一种秸秆水煤浆的表面添加剂及其应用方法。本发明包括以下组份按重量份数比组成：木质素磺酸盐：60～85份；聚乙二醇：5～10份；煤焦油：10～30份。本发明大幅降低了生物质秸秆粉末的吸水性，通过阴离子和非离子表面活性剂的协同作用，增强了煤粉和生物质秸秆粉末的疏水性，提高了煤粉和生物质秸秆颗粒表面的zeta电位，进而提升了其在水中的分散性。该生物质秸秆水煤浆体具有较好的流动性、较低的表观粘度和良好的稳定性。复配表面添加剂原料价格低廉，容易购买，同时该复配添加剂生产工艺简单，性能较好。
摘要（英）：

Belonging to the technical field of coal water slurry, the invention in particular relates to a surface additive of a biomass coal water slurry and an application method thereof, in particular to a surface additive of a straw coal water slurry and an application method thereof. The surface additive comprises the following components by weight: 60-85 parts of lignosulfonate; 5-10 parts of polyethylene glycol; and 10-30 parts of coal tar. The surface additive provided by the invention greatly reduces the water absorption capacity of biomass straw powder, strengthens the hydrophobicity of pulverized coal and biomass straw powder through the synergistic effect of anionic and nonionic surfactants, and enhances the zeta potential on the surfaces of pulverized coal and biomass straw particles, thus enhancing the dispersibility in water. The biomass straw coal water slurry has good flowability, low apparent viscosity and good stability. The compound surface additive has cheap and easily purchasable raw materials, and the compound additive also has the advantages of simple production process and good performance.
