Acid corrosion inhibitor RS-02
Corrosion inhibitor RS-02 is used to protect equipment made of alloy steel in the medium of aqueous solution of ortho-phosphoric acid in closed production cycles. Volume and frequency of inhibitor supply to the cycle is calculated and agreed with the production for each case individually, according to the technological process used in this production. The inhibitor provides effective and reliable protection against acid corrosion, it is highly adsorbable in relation to metal surfaces, and it significantly reduces general and pitting corrosion.
