STUDY ON ANTI-OXIDIZES THE FLEXIBLE GRAPHITE IN LOW SULPHUR COMPOUND SEALS MATERIALS

Aiming at current graphite seals completely the ware anti-oxidizes the function bad,seal completely the function not high,leak iness problems choose to use the potassium premanganate to make the oxidizing agent mixed with the oil of vitriol,irons trichloride make the catalyst inserts,jot hydrogen pero-xide make the catalyst,adopting the half solid phase to impregnating made the expansible graphite.At will its impregnation with the cane sugar boric acid grease aqua,dehydrate,the low temperature is dry,the heat inflation inhibits formed the high anti-oxidizes the flexible graphite in low sulphur compound seals materials,The product to contain the sulphur lower than 5.0×10~(-4)?the anti-oxidizes the ability strengthen a times are above,leaking the rate under the situation of lying quality pressure 10.0 MPa smaller 0.0001.Research result express adoph this kind of new craft can improve the graphite seals materials function,from but betterly satisfy usage request.
