Abstract

Inventia de fata se refera la o solutie de protectie anticorosiva a tirantilor pretensionati ancorati în teren, caracterizata prin aceea ca, în scopul asigurarii unui strat protector rezistent si foarte aderent, este constituita din circa 40...60% un amestec format dintr-un ulei parafinos si parafina, 10...25% benzensulfonat de bariu industrial, 25...40% un solvent petrolier rafinat, cu punct de inflamabilitate de minimum 35 degree C, si 0,1...4% fata de cantitatea de unsoare utilizata, inhibitori de coroziune, de preferinta stearat sau ditiofosfat de zinc. Procedeul de obtinere a solutiei, conform inventiei, se caracterizeaza prin aceea ca, în scopul injectarii solutiei anticorosive la temperatura de +10...35 degree C si sub presiune constanta de 2...3at, pe o zona libera a unui tirant, în interiorul unei tevi de polietilena în care se afla o armatura de otel, se încalzeste la temperatura de 70...95 degree C un amestec de ulei parafinos si parafina în proportie de 40...60% cu 10...25% benzensulfonat de bariu industrial, dupa care se adauga ciment sau white-spirit pentru marirea, respectiv micsorarea vîscozitatii, se omogenizeaza din nou amestecul timp de 2 min, încalzindu-se apoi la o temperatura de 40...50 degree C.The present invention relates to an anticorrosive protection solution of the anchor pretensioners anchored in the field, characterized in that, in order to provide a durable and highly adherent protective layer, it consists of about 40 ... 60% of a mixture consisting of paraffin oil and paraffin oil, 10 ... 25% industrial barium benzenesulfonate, 25 ... 40% a refined petroleum solvent with a flash point of at least 35 ° C and 0.1 ... 4% relative to the amount of used grease, corrosion inhibitors, preferably stearate or zinc dithiophosphate. The process for obtaining the solution according to the invention is characterized in that, for the purpose of injecting the anticorrosive solution at a temperature of +10 ... 35 ° C and under a constant pressure of 2 ... 3 °, on a free zone of a tie, In a polyethylene pipe having a steel reinforcement, a mixture of paraffin oil and paraffin oil is heated at a temperature of 70 ... 95 ° C in a proportion of 40 ... 60% with 10 ... 25% industrial barium benzenesulfonate, after which cement or white spirit is added to increase or decrease the viscosity, the mixture is again homogenized for 2 minutes, then heated to 40-50 ° C.
