架桥剂学名：封闭型水性固化剂（非离子型交联剂）别名：架桥剂、固化剂、交联剂、固色剂、接着剂、增进剂、补强剂、牢度提升剂。主成分： 封闭多异氰酸酯。该系列固化剂常温下可与水性树脂（水性聚氨酯、水性丙烯酸酯、氟乳液、有机硅乳液等）长期稳定共存，热处理时该固化剂释放出的异氰酸酯（-NCO）基团与水性树脂分子链上羟基、羧基、氨基等基团反应形成交联结构，可显著改善水性树脂性能。
考察的主要因素包括药物浓度、温度、表面活性剂和架桥剂用量及搅拌速度。
The major factors investigated included the concentration of drug in ethanol, temperature of system, the amounts of surfactant and bridging agent as well as agitation speed.
这种絮凝剂具有网状结构，将污水中的悬浮颗粒通过架桥作用絮凝沉淀下来。
It has netted structure, so in waste water, the suspending particle is deposit by bridging.
微生物絮凝剂在水系中主要起吸附架桥的作用。
The microbial flocculant has the absorption and bridge effect.
