n. 木素磺化鹽
The fluid type of sodium lignosulphonate coating is yielding pseudoplastic fluid.
木鈉塗料的流體類型為屈服假塑性流體。
The SRA has better effect than lignosulphonate calcium as the forming retarded time is longer.
在延遲成型時間較長時,SRA起到的緩凝作用比木鈣更明顯。
The invention discloses a water shutoff agent for oil extraction, which is prepared by mixing epoxy resins, polyethylene ammonia, calcium lignosulphonate, calcium chloride and water.
本發明公開了一種采油用堵水劑,由環氧樹脂、聚乙烯聚氨、木質素磺酸鈣、氯化鈣、水混合組成。
An excellent pumping admixture was made up by use of FDN compounded with calcium lignosulphonate, retarder for controlling slump loss and water retaining admixture for reducing water segregation rate.
FDN與木鈣複合,以緩凝劑控制坍落度經時損失,以保水劑降低混凝土泌水率,配制出混凝土坍落度經時損失較小、性能優良的多元複合泵送劑。
木質素磺酸鹽(Lignosulphonate)是一種從木質素中提取的有機高分子化合物,主要來源于造紙工業的副産品亞硫酸鹽制漿過程。在化學結構上,它由木質素分子與磺酸基團結合形成水溶性聚合物,分子量範圍通常在1,000至140,000道爾頓之間。
該物質的主要應用領域包括:
其化學性質表現為陰離子表面活性,pH值適用範圍為4-10,熱穩定性可達200℃。生産過程中通過亞硫酸鹽與木質素的磺化反應實現,反應方程式為: $$ text{Lignin} + text{HSO}_3^- rightarrow text{Lignosulphonate} + text{H}_2text{O} $$
Lignosulphonate(或拼寫為lignosulfonate)是一種由木質素經過磺化反應生成的有機化合物,屬于木質素衍生物。以下是詳細解釋:
