捕收

The specially designed wire-catch mechanism makes spool-changing have successfulness up to 99%.

适用Φ500-Φ630 两种国际线盘，双盘连续收线，特殊设计的捕线结构使换盘成功率高达99%。

Secondly, certain rare wild anima ls that are going to be extinct should be collected, fed and reproduced arti ficially.

其次，有些濒临灭绝的珍稀野生动物应该收捕，人工喂养并繁殖。

The degradation properties of sulfide flotation collectors such as Xanthogenate, Dithiocarbamate, Dithiophophate, N,N-dialkyl-dithiocarbamatecyanoethylene and Thionocarbamate are studied in this paper.

论文研究了黄原酸盐、氨基二硫代甲酸盐、二硫代磷酸盐、氨基二硫代丙烯腈酯、氨基硫逐甲酸酯等硫化矿捕收剂的降解性能。

The results show that methyl group strengthens the electrostatic attractions, but reduces the H-bonds effect, while benzyl group can make both electrostatic and H-bond effects strong. The theoretical results are identical with the results of the collectors flotation tests. Collecting ability of the quaternary amine salts is better than that of dodecylamine and dodecyl bimethyl amine. The quaternary amine salt containing benzyl group performs best, and it is little affected by pH value. Substitution of N-containing polar group in amine collectors can impact the aluminosulicate minerals flotation.

研究结果表明：甲基的取代可增强阳离子的静电作用能力，同时，削弱它与矿物表面之间的氢键作用；苄基的取代不仅增强药剂的静电效应，而且增加氢键的结合能力；理论分析结果与浮选试验结果一致，季铵盐的浮选能力较伯胺与叔胺的强，连有苄基的季铵盐对铝硅酸盐矿物的捕收能力最强，且受pH值影响小。

Analyzed the reason of high sulphur content in concentrated iron powder and studied the influence of milling fineness, PH value of pulp, used quantity of activator on rate of recovery of floatation adopting 307 ore sample as sample.

以307#矿样为试样，分析了铁精粉含硫高的原因，研究了磨矿细度、矿浆pH值、捕收剂及活化剂用量等对浮选回收率的影响。

RA—315 is an efficient collector which is prepared by choridization and oxidization of tall oil as its essential raw material, followed by further processing of it.

RA—315捕收剂是以塔尔油为主体原料，经氯化反应和氧化反应后进行进一步加工处理而得。
