Demonstrated by adsorptive capacity and adsorptive energy, polyacrylamides have strong interaction on mineral surface with similar action mode to that of starches, for example, hydrolyzed polyacrylamide and hydroxamic acid polyacrylamide mainly by chemical force, cationic polyacrylamide by electrostatic force and hydrogen bond, nonionic polyacrylamide by hydrogen bond, while amphoteric polyacrylamide embodying both the characters of anionic and cationic one.

聚丙烯酰胺类化合物在矿物表面的吸附能以及吸附量均显示出药剂与矿物间存在的强作用，作用方式与淀粉类药剂相似：阴离子聚丙烯酰胺、羟肟酸聚丙烯酰胺主要靠化学作用，阳离子聚丙烯酰胺借助静电力和氢键，非离子型的聚丙烯酰胺则主要是氢键作用，两性聚丙烯酰胺同时具有阴离子和阳离子聚丙烯酰胺药剂的作用特点。

The anti-jamming ability of igniter depends on the charge in the igniter. The combustion of the igniter charged with barium nitrate and those charged with magnesium powder and PTFE is stable, while the igniter charged with zirconium hydride and lead oxide is unstable. The standard error of duration of the third kind of igniter flame is 523 ms ,and also its nozzle hole is blocked seriously.

不同药剂的点火具抗干扰性能不同，其中以硝酸钡为药剂主成分的点火具和以镁粉＋PTFE为药剂主成分的点火具燃烧性能稳定，以氢化锆、二氧化铅为药剂主成分的点火具工作稳定性较差，火焰持续时间标准差为523 ms，点火具喷孔堵塞严重。

In the pH range of 6~12, the results of the flotation tests indicate that the performance of the new combined cationic collector (CS3:CS1=3) and (CS3:CS2=2) is similar, and they are effective collectors for reverse flotation of the iron ores. The combined cationic collectors exhibited the same collectability as dodecylamine, but better selectivity than dodecylamine. By using the combined collector, the dosage of the collector decreased from 1 10-4mol/L to 1 x 10-5mol/L .

单矿物可浮性试验结果表明，在pH=6～12的范围内，新型组合药剂CS_3：CS_1=3和CS_3：CS_2=2具有相近的药剂性能，在其捕收能力与十二胺相当的前提下，不但选择性较十二胺好，而且还能显著提高药剂的协同效应，使药量从单用时的1×10~(-4)4mol／L降至1×10~(-5)mol／L，是铁矿石反浮选的高效捕收剂。
