Examples
- Tannin one of a mixed group of substances that , as defined by industry , precipitate the gelatin of animal hides to form leather
鞣质：工业上用于将动物的兽皮中的明胶沉淀出来而炼成皮革的混合物材料之一。 - The urea - formaldehyde ( uf ) polymer / sio2 composite microspheres were prepared by polymerization - induced colloid aggregation ( pica ) method . the formation mechanism of composite microspheres is attributed to the fact that that urea and formaldehyde firstly undergo acid - catalyzed polymerization to form oligomers , and then the sol particles are adsorbed on the chain of oligomers by wan der walls force and hydrogen bonding . when the oligomers reach the critical chain length , they separate from solution due to phase separation
对复合微球形成机理的研究表明，尿素和甲醛在酸性条件下自身聚合可以形成高分子微球，在sio _ 2酸性溶胶中发生聚和反应时，随着反应的进行，齐聚物不断生成， sio _ 2胶体颗粒逐渐吸附在齐聚物分子链上，当聚合物链达到沉淀临界链长时，由于相分离作用，从前驱物溶液中析出，同时sio _ 2胶体颗粒均匀的分布在脲醛聚合物网络中，随之沉淀出来，形成脲醛sio _ 2复合微球。
