Способ заключаетс в обработке отложений водным р ст вором полимера-иономера серии ВНИИолефин с концентрацией 0,315- 0,405 мас.% и содержанием амидных и карбоксильных звеньев в макромоле- кул рной цепи при соотношении 30- АО и 60-70 мол.% соответственно. Обработку ведут в течение 20 мин и затем раствор сливают. Дл испытани на эффективность образец сушат в токе теплого (70 С) азпта, затем пропускают воздух и измер ют температуру окислени (самонагревани ). 1 табл. Ф (ЛThe invention relates to methods for preventing spontaneous combustion of pyrophoric iron sulfide deposits and improves efficiency, reduces the cost of the process and creates safe working conditions. The method consists in treating the deposits with an aqueous solution of the polymer-ionomer of the VNIIolefin series with a concentration of 0.315-0.4005 wt.% And the content of amide and carboxyl units in the macromolecular chain at a ratio of 30 AO and 60-70 mol%, respectively. Processing is carried out for 20 minutes and then the solution is drained.

Целью изобретени вл етс повышение эффективности, удешевлени процесса и создание безопасных условий труда.The aim of the invention is to increase efficiency, reduce the cost of the process and create a safe working environment.
Пример. 5 г активного (пирофорного ) сульфида железа, приготовленного взаимодействием сероводорода с окисью железа, обрабатывают 5 мл 0,1 мас.% водног о раствора полимера- иономера серии ВО, имеющего 40 мол.% амидных звеньев и 60 мсл.Х, карбоксильных. Затем выдерживают в течение 20 мин и сливают раствор.Example. 5 g of active (pyrophoric) iron sulphide prepared by reacting hydrogen sulfide with iron oxide are treated with 5 ml of a 0.1 wt.% Aqueous solution of a VO series polymeric ionomer solution having 40 mol.% Amide units and 60 msl.X, carboxyl. Then incubated for 20 minutes and drain the solution.
Дл вы снени эффективности процесса предотвращени самовозгорани обработанный образец сушат в течение 2 ч под потоком теплого азота () и определ ют его активность. Дл этого через образец со скоростью 1 л/мин подают воздух и измер ют тем пературу окислени (самонагревани ). В таблице даютс примеры зависимо сти максимального температурного значени самонагревани от кон 1ентра ции водного раствора полимера-иономе ра серии во и соотношени амидных и карбоксильных звеньев в макромоле- кул рной цепи в полимере.To clarify the effectiveness of the spontaneous combustion prevention process, the treated sample is dried for 2 hours under a stream of warm nitrogen () and its activity is determined. To do this, air is supplied through the sample at a rate of 1 l / min and the temperature of oxidation (self-heating) is measured. The table gives examples of the dependence of the maximum temperature value of self-heating on the concentration of an aqueous solution of the polymer-ionomer series in and the ratio of amide and carboxyl units in the macromolecular chain in the polymer.
