Description

Известно применение в качестве ингибиторов тринатрир1фосфата ЫазР04 двухромовокислого кали  (хромпика) К2Сг207 в смеси с содой NagCOs дл  зашиты от коррозии внутренней поверхности системы охлаждени  двигателей внутреннего сгорани  и других металлических деталей , передаваемых на базисные склады на длительное хранение.It is known to use potassium dichromate (chromic) K2Cg207 as a trinatriphosphate azP04 inhibitor in a mixture with NagCOs soda for corrosion protection of the internal surface of the cooling system of internal combustion engines and other metal parts transferred to basic warehouses for long-term storage.

Однако при резких колебани х температуры воздуха (осень, весна) на металлических поверхност х системы охлаждени  и на других детал х машин образуетс  конденсат, отрицательно вли ющий на действи  ингибитора, не имеющего в своем составе защищающих компонентов и достаточного количества глицерина.However, with sharp fluctuations in air temperature (autumn, spring) condensate forms on the metal surfaces of the cooling system and on other parts of the machine, adversely affecting the action of the inhibitor, which does not contain protective components and a sufficient amount of glycerin.

В предлагаемом способе приготовлени  консервирующего состава, продолжительное врем  предохран ющего металлические поверхности от 1 оррозии, нар ду с реагентами, вход щими в состав ингибитора, примен ютс  водно-глицериновые смеси, загущенные картофельным крахмалом , замерзающие при температуре минус 40°, а также и трехкомпонентные присадки, состо щие из двухромовокислого кали , азотистокислого натри  и тринатрийфосфата в смеси с кальцинированной содой.In the proposed method of preparing a preservative composition, which for a long time protects metal surfaces from 1 orosia, along with the reagents included in the inhibitor, water-glycerin mixtures thickened with potato starch, freezing at a temperature of minus 40 ° C, as well as three-component additives consisting of potassium dichromate, sodium nitrite and trisodium phosphate mixed with soda ash.

Рекомендуетс  примен ть следующие составы консервирующих смесей:It is recommended to use the following preservative mixtures:

а)Дл  водно-глицериновой смеси глицерина - 70%, воды - 30% и крахмала - 3-4% от веса смеси.a) For a water-glycerin mixture of glycerin - 70%, water - 30% and starch - 3-4% by weight of the mixture.

б)Дл  универсального ингибитора двухромовокислого кали  или натри  - 0,75-1,0% в смеси с 1,5-2% соды или трехкомпонеитной присадки , состо щей из двухромовокислого кали , азотистокислого натри  и тринатрийфосфата в количестве по 0,05% каждого компонента с 0,5- 0,6% кальцинированной соды на консервирующий раствор.b) For a universal inhibitor of potassium dichromate or sodium, 0.75-1.0% mixed with 1.5-2% soda or a tricomponeite additive consisting of potassium dichromate, sodium nitrite and trisodium phosphate in an amount of 0.05% each component with 0.5-0.6% soda ash per preservative solution.
