METHOD FOR PRODUCING MEANS FOR CLEANING AND CORROSION PROTECTION OF SURFACES OF HEAT-TRANSFER APPARATUSES AND PIPELINES AND METHOD FOR CLEANING AND CORROSION PROTECTION OF HEAT-TRANSFER APPARATUSES AND PIPELINES

摘要

FIELD: thermal engineering; cleaning, corrosion protection, and scale removal methods for heat exchangers, pipelines, heating and water supply systems, etc. SUBSTANCE: natural finely dispersed mineral material is mechanically activated in aqueous medium at pulsating pressure of 0 to 1.6 MPa and temperature of 20-80 C, pulses being supplied at frequency of 40-60 Hz. Fineness of mineral material attained in the process is 1-10 mcm. Primarily used as source material are natural albitophyres or diabases containing in their composition at least 30% of silicon dioxide SiO₂. Method for cleaning and corrosion protection of heat-transfer apparatuses and pipelines involves introduction of mechanically activated powdered albitophyres or diabases in the amount of 0.8-1.5 g/l in circulating water. EFFECT: enhanced cleaning effectiveness and long-time protection of treated surfaces against scale, corrosion, and other deposits. 5 cl, 2 tbl, 3 ex
