Steel structure surface rust removing agent
The invention discloses a steel structure surface rust removing agent. The steel structure surface rust removing agent consists of the following raw materials in parts by weight: 45-50 parts of acrylic resin, 30-40 parts of organic silicon resin, 10-15 parts of fire retardant, 1-3 parts of corrosion inhibitor, 1-3 parts of penetrating agent, 4-8 parts of triethanolamine, 45-55 parts of de-ionized water, 4-6 parts of ethylene oxide, 3-6 parts of ammonium molybdate, 0.3-0.5 part of sodium ethylenediamine tetramethylene phosphonate, and 1-3 parts of fatty alcohol polyoxyethylene ether sodium sulfate, wherein the fire retardant is one or two of ammonium polyphosphate and pentaerythritol. The steel structure surface rust removing agent is different from a traditional acid rust removing agent, contains no strong acid and chloride ion component, and is free of corrosivity, low in cost, safe, environment-friendly and excellent in rust removing effect.

Cement paste system for long-cementing-section large-temperature-difference cementing
ActiveCN112961658ASatisfy retardationWide use temperature rangeDrilling compositionMeth-Ethylenediaminetetra(methylenephosphonic)acid
The invention discloses a cement slurry system for long-cementing-section large-temperature-difference cementing, and relates to the technical field of oil and gas field cementing materials. The cement paste consists of 74-88 wt% of oil well cement, 4-8 wt% of a fluid loss agent, 1-3 wt% of a suspension stabilizer, 10-20 wt% of a high-temperature strength stabilizer and 1-3 wt% of a retarder. The retarder is formed by mixing and compounding sodium ethylene diamine tetramethylene phosphonate, borax and a ternary polymer. The ternary polymer is prepared by taking sodium methallyl sulfonate, isopentenol polyvinyl ether and maleic anhydride as monomers and adopting a free radical solution copolymerization method. The cement paste provided by the invention has a wide use temperature interval, can meet the retarding effect on cement paste in the whole temperature interval that the temperatures of the upper end and the lower end of a cement paste injection well section in cementing construction are 50 DEG C and 180 DEG C respectively, the cement paste is ensured to have certain strength in a 50-DEG C high-temperature large-temperature-difference environment at the top, and the super retarding phenomenon of top cement is avoided.
