Неионогенные ПАВ Аф-10 и АФ-12 производ т по ТУ 38.103625-87. Продукт полимеризации диметилдиаллилам- монийхлорида (полиэлектролит) производ т по ТУ 6-05-231-238-83 и примен ют в народном ход йстве в качестве флотореагента, коагул нта в производстве вакцин, а также при очистке сточных вод.Non-ionic surfactants Af-10 and AF-12 are produced according to TU 38.103625-87. The product of polymerization of dimethyl diallylammonium chloride (polyelectrolyte) is produced according to TU 6-05-231-238-83 and is used in the national course as a flotation reagent, coagulant in the production of vaccines, as well as in wastewater treatment.
При контакте неионогенного ПАВ и полиэлектролита в водном растворе образуютс комплексы, что упор дочиО1Upon contact of a non-ionic surfactant and polyelectrolyte in an aqueous solution, complexes are formed, which are ordered as O1
вает структуру предлагаемого состава и улучшает его нефтевытесн ющие свойства .structure of the proposed composition and improves its oil-driving properties.
Дл приготовлени состава пригодна вода практически любого состава и минерализации , в том числе сточна ,For the preparation of the composition suitable water of almost any composition and salinity, including wastewater,
В предлагаемом составе расход не- :ионогенного ПАВ на 1,5 масД ниже, чем в известном,In the proposed composition, the consumption of non-: ionic surfactant is 1.5 masD lower than in the known
Область применени состава по тем- 1пературе и минерализации вод не огра- ничена,The scope of application of the composition by temperature and mineralization of water is not limited,
I Готов т состав,содержащий 0,5 мае.% ПАВ типа АФ-10 и 0,5 мас.% полиэлект:ролита - продукта полимеризации ди- метилдиалли аммонийхлорида в воде. п этого 5 кг ПАВ АФ-10 и 20 кг i25%-Horo водного раствора полиэлект- пролита смешивают в растворном узле I кустовой насосной станции с 975 кг воды.
