FIELD: construction. ^ SUBSTANCE: for prevention and elimination of gas leaks via stop valves leak passages at the range of working environment temperatures from minus 45C to plus 160C and higher, and also for corrosion prevention in metal parts of sealing units that operate in above mentioned ranges of temperatures, paste contains the following components in wt %: graphite colloid preparation 1.5-9.0, polytetrafluoroethylene 5-14, multifunctional additive 2.5-7.0, mineral oil thickned with lithium-zinc soaps of synthetic fatty acids up to 100. Multifunctional additive contains 1.4-di(N-arylsulfonylamino)-2(thiobezthiasol)benzol. ^ EFFECT: increased efficiency of stop valves operation due to leaks reduction via its stop unit. |
