Definitions

  • the present disclosure relates to a rust removing composition, in particular to a rust removing composition for metals, which is useful for cleansing metal apparatuses for medical or commercial use.
  • Stainless steel medical apparatuses tend to rust and corrode during use, mainly for the following three reasons. Firstly, the apparatuses often come into contact with organic contaminants such as disinfectants, human secretions, bodily fluids or blood stains. Salts and iodides contained in the organic contaminants are corrosive and destructive to the chromium layer of the apparatuses. Particularly, dried organic contaminants on the apparatuses are more destructive. Secondly, the apparatuses are generally subjected to chemical or physical disinfection after use. Chlorine-containing disinfectant solutions, peracetic acid, acidic electrolyzed water as well as high-temperature and high- humidity environments will oxidize and corrode the nickel-chromium layer or even the iron of the apparatuses. Thirdly, during cleansing of the apparatuses, many improper operations, such as using a steel wire ball or a hard bristle brush to scrub the dried blood on the apparatuses, will lead to the destruction of the chromium layer of the apparatuses.
  • organic contaminants such as disinfectants
  • rust removing agents in relevant patents and literatures mainly focuses on those for industrial use. These rust removing agents are generally compositions of hydrochloric acid and surfactants, and as such they are highly corrosive to metals (e.g. U.S. Patent No. 5,215,676). Some literatures disclose rust removing agents which are compositions of phosphates, surfactants and corrosion inhibitors but have slow speed and moderate rate of rust removal (e.g. U.S. publication No. 2009032058A, CN101463481A, etc).
  • the present disclosure provides a rust removing composition capable of being used for removing rust from metal apparatuses for medical or commercial use, especially stainless steel apparatuses.
  • the composition has not only a faster speed and a high rate of rust removal but also a lower corrosiveness to metals.
  • the present disclsoure provides a rust removing composition, comprising, based on the total mass of the composition:
  • a penetrant selected from the group consisting of at least one of C2-C4 short-chain ethers and short-chain alcohols;
  • the rust removing composition of the present disclosure (sometimes referred to as "highly effective rust removing corrosion inhibitor composition" in the present specification) can effectively remove rust spots, corrosion spots as well as other corrosive substances, and is especially suitable for soaking rusty metals after dilution. Moreover, in some embodiments, the composition will not, after use, result in severe corrosion to metal surfaces and re -rusting, thus preventing secondary rusting and corrosion of metals. It is a water soluble rust removing agent, being easy to dilute for use, and is safe to use. In some embodiments, the rust removing composition achieves a rust removal rate of more than 50% for rust spots of common stainless steel medical apparatuses after soaking the apparatuses for 15 minutes.
  • the term “physically stable” means no significant changes from the initial state occur due to obvious precipitation, crystallization, phase separation or the like, when kept at room temperature for at least 3 months.
  • short-chain ethers means alkyl ethers containing 2 to 4 carbons.
  • short-chain alcohols means alkyl alcohols containing 2 to 4 carbons.
  • the rpesent disclosure provides a rust removing composition, comprising, based on the total mass of the composition:
  • a penetrant selected from the group consisting of at least one of C2-C4 short-chain ethers and short-chain alcohols;
  • Inorganic acids suitable for use in the present disclosure are preferably medium strong acids, including but not limited to phosphoric acid, metaphosphoric acid, boric acid etc. Such inorganic acids are very reactive with metal ions and prone to form chelates with metals dissolved out, serving the purpose of masking. Also, these inorganic acids are poorly volatile and will not generate acid mist, therefore they will not contaminate the surroundings and do harm to the users. More preferable inorganic acids are phosphoric acid or metaphosphoric acid. Phosphate or metaphosphate ions have a good ability to complex ferrous and ferric ions, forming a dense passivation film on the surfaces of stainless steel substrates and preventing further corrosion of the stainless steel metal.
  • the inorganic acids are present in the composition in an amount in the range of from 10 to 20% by mass, preferably from 15 to 20% by mass, and more preferably from 18 to 20% by mass.
  • an amount of below 10% by mass will not achieve the expected rust removing effect; while an amount of more than 20% by mass will be corrosive to metal surfaces.
  • Organic acids are preferably anionic compounds which are capable of complexing with multivalent metal ions, serving the purpose of accelerating rust removal and lengthening the lifetime of the rust removing agent.
  • organic acids include but are not limited to citric acid, oxalic acid, aminosulfonic acid, lactic acid, malic acid, tartaric acid, glycolic acid, acetic acid, propionic acid, benzoic acid, nonylbenzoic acid etc., more preferably citric acid and aminosulfonic acid, and most preferably citric acid.
  • the organic acids are present in the composition in an amount in the range of from 1 to 10% by mass, preferably from 4 to 10% by mass, and more preferably from 5 to 8% by mass.
  • Penetrants can be organic or inorganic penetrants. They can help the bulk rust removing agent to rapidly penetrate a rust film, and, during this process, loosen the adherence of the rust film to the underlying steel surface, thereby promoting pentration and wetting and enhancing the rust removing effect.
  • penetrants include but are not limited to dipropylene glycol monomethyl ether, ethylene glycol butyl ether, ethylene glycol ethyl ether, sodium chloride, magnesium chloride, sodium sulfite, etc.
  • the preferable penetrants are organic fatty alcohol polyether penetrants.
  • such penetrants can not only facilitate rust removal, but also form some anti-corrosion components by complexing with iron ions, and inhibiting the generation of acid mist as well.
  • the most preferable penetrant is dipropylene glycol monomethyl ether, which has a low surface tension and can rapidly penetrate the rust layer through the pores therein, thereby facilitating the accelerated penetration of the bulk rust removing agent.
  • the penetrants are present in an amount in the range of from 1 to 8% by mass, preferably from 1 to 5% by mass, and more preferably from 2 to 5% by mass, based on the total mass of the composition.
  • the composition also comprise sulfonic acid and/or sulfonate type anionic surfactants, preferably sulfonate type anionic surfactants.
  • sulfonic acid and/or sulfonate type anionic surfactants include but are not limited to alkylsulfonic acids, benzene-containing sulfonic acids and alkyl sulfonates, etc.

  • the surfactants are present in the composition in an amount in the range of from 2 to 10% by mass, preferably from 4 to 8% by mass, and more preferably from 5 to 6% by mass.
