Annotatsiya: Epoksid smolasi va polisulfid oligomeri asosidagi qoplamalarning agressiv muhitlarda barqarorligini baholash va laboratoriya retsepturasini texnologik reglamentga o‘tkazish yondashuvi ishlab chiqildi. 10 massa % H₂SO₄, 10 massa % HCl, ishqoriy eritma, 3,5 massa % NaCl va model uglevodorod muhiti uchun qiyosiy sinov matritsasi taklif etildi. Qoplama massasi o‘zgarishi, metall korroziyasi, elektroximiyaviy impedans va adgeziya saqlanishini alohida baholash asoslandi. Potensiodinamik polyarizatsiyadan korroziya tokini aniqlashning qo‘llanish shartlari belgilandi. Ikki komponentli kompozitsiyani tayyorlash, sirtga surkash, qotirish va partiya nazoratining texnologik tartibi hamda maydon birligiga xarajat hisoblash usuli keltirildi. Tajriba-sanoat va iqtisodiy natijalar tasdiqlangan ko‘rsatkich sifatida berilmagan.References
