Temporary rust
end et al (J.App1.Chem., 19S3.3) raised the concentration of lanolin under irrigation to 12.5% resistance, the ability of emergency Wei rust down, when and wax, resin with the Si, the effect can be increased. For example, the formula used are: ① paraffin oil I32, mineral oil: 15,[link widoczny dla zalogowanych], lanolin: 32, mica powder: 18. ② poly ethyl methacrylate: 33 ~ 67, lanolin: 8 to 12, fatty acid amide I33 ~ 406) phenol; phenol and aminophenol frequent in the E industry as antioxidant additive components, the word for rust The long chain alkyl phenols are mainly (USP - 250] 991), alkyl phenol and formaldehyde material reduction units (USP - 2409303), alkyl phenols and alkynes of shrinking sets things ~ USP - 2594795) octyl catechol, acylation of a P-amino phenol (USP A 2,629,666), etc. 7) t generally higher fatty acid ester ester dollar anti-corrosion effect is not high, it is because it is adsorbed on the surface of gold dimple low can not form a firm to protect the eyelashes, only the polar alcohols are rust effects,[link widoczny dla zalogowanych], such as glycerol and propylene glycol higher fatty acid ester with rust capability, sorbitol quarter circle alcohol monoester E particularly effective. When the fatty amines and fatty amine salts when used with better platform. phosphate and phosphorothioate; is phosphoric acid and thiophosphate as a softener and softener used, the adsorption capacity, and set poor rust. 9) acid; early multi-rust agent and lubricant additives, as it is petroleum refining by-product of petroleum sulfonate, mainly single-and two acid alkali salt, calcium, barium, aluminum,[link widoczny dla zalogowanych], ammonium, amine salt and so on. Industrial use of petroleum sulfonates usually contain mineral oil l0WO%, a dark brown viscous yellow substance, the general formula CH2 a losOaMe (n> 20), 3 to 6 molecules in the tenth ring. Ha petroleum sulfonate in mineral oil can be dissolved in water, dispersion cents good, widely used as anti-rust oil; molecular weight of 600 ~ 7O0 ~ 500 than the 400 effect. 10) {sulfonamide acid molecule has a sd: a base and a NH - COOH, are surface active groups, early called EmulphorSTH (Hbchst) Debate in the water wash the product has strong corrosion resistance. Energy (USP2578725) ・ l5 ・ pool VD】 Corrosion Engineering. 】 7, No. 4,198911) amine: The early use of amines to prevent corrosion of iron and the mechanism for a large number of research work. C. A. Mann and put forward better than low-level high amine amine good. RNHz to accept protons in acidic solution (H) into ammonium that is generated R-NH. Ions. Post it on the iron I love the negative charge region and the e form ionic bonds, van der Waals force is not simply physical adsorption. Anti-rust and acid, as the number of alkyl of c more rust within a certain range the stronger the ability, the higher the intensity of the ammonium ion, the stronger the effect of such amine: amine the strongest, the weakest tertiary amines. Showed a sharp decline. The role of alkyl amines in principle, anti-rust molecular structure of the acid than the same low-1 /] o, it is required to use higher concentrations. Generally speaking ability of low aromatic amine rust (I.E ... C1948, 40,2338). Diphenylamine and phenyl amines are used for tea and its antioxidant effect, compared with the effects of rust. In principle,[link widoczny dla zalogowanych], secondary amine (PEI) worse than the effect of amine rust, but there are some experimental results with this thesis different. N. Hackerman (Corrosion】 962, l8, 400 that the same molecular weight of the chain} imine and cyclic imide rust on low carbon steel compared with the role of anti-rust capacity than the larger ring imine, with the effect of molecular weight increase improved. wrapped 3 amine amine salt corrosion octadecylamine CiBH3v-NH2-second deaf Cl2H25 a NH: Ten amine C ¨ H ¨ a TOA C8Hl5-NHz NH2 cyclohexyl deaf CBHIl-NH: oxidation of organic acids fI paraffin i grate f j Fu Xue fat child twelve (alkyl) acetic acid Iil I bitter 【twelve (alkyl) l acid oxidation oxide paraffin wax 【I long-chain amine oxide paraffin I95T0l5 poor water solubility itself, the actual use, often in the form of its salts, from the fatty acid composition of salt used in its ability to have greater impact rust noon. For example, ・ 16 ・ J. P. Barret: ~ Corrosion, l955, 2,217) that the molecular weight of fatty acids greater fatty acid amine salt corrosion better the performance. The most efficient steel pickling corrosion additive HerCulesPowder. Co rosin amine D, which is a male and soluble in hydrochloric acid, insoluble in water
