Abstract:
     This invention provides a process for producing a protective agent used for sarface dedusting and corrosion-proofing of chrome-plated work pieces. It uses phosphoric acid as main constituent and is supplemented with auxiliaries and additive to form a phosphorized dedusting agent and uses mineral oil as main constituent supplemented with additive to form a corrosion-resistant agent (oil-base). Said two products are applied in a complete set, the former is used for dedusting and phosphoration of chrome-plated work pieces, while the latter is applied for forming a protective layer on surface of chrome-plated work pieces. Thus, two aims of dedusting and corrosion-proofing are achieved.
