Umenzeli we-antirust agent

Eyaziwa nangokuthi i-oil-soluble corrosion inhibitors. Iningi lazo zingamakhemikhali amade we-carbon chain organic namaqembu we-polar. Amaqembu asezindaweni eziphakeme kuma-molecule awo adonswa eduze ebusweni bensimbi ngokukhokhiswa; amaqembu anga-polar wamakhabhoni ama-hydrocarbon amakhulu e-carbon aqondiswe ngaphandle kwendawo yensimbi, futhi angancibilika ngoyili, ukuze ama-molecule we-antirust agent ahlelwe ngokuqonde ebusweni bensimbi, akhe ifilimu evikelayo yokukhangisa ukuvikela insimbi evela ekugugulekeni kwamanzi ne-oxygen. Ngokweqembu laso le-polar, lingahlukaniswa ngezigaba ezinhlanu: ① i-sulfonate, ifomula lamakhemikhali ngu (R-SO3. Ngokuvamile kusetshenziswa usawoti wensimbi noma i-alkaline earth salt usawoti we-petroleum sulfonic acid, njenge-barium petroleum sulfonate, i-sodium petroleum sulfonate , i-barium dinonylnaphthalene sulfonate njalonjalo. Ama-Carboxylic acids nezinsipho zawo, ifomula lamakhemikhali le-R-COOH ne (R-COO) nMm. njengoba i-rust inhibitor carboxylic acid ingamafutha wezilwane nemifino ka-fatty acids, njenge-stearic acid, i-oleic acid, njll, enye i-oxyfuel, i-alkenesuccinic acid namanye ama-carboxylic acid, kanye nemikhiqizo kaphethiloli efana ne-naphthenic acid. ukuncibilika kukawoyela kuncane. Futhi izofakwa i-hydrolyzed ngamanzi, futhi ayizinzile kangako lapho ihlakazeka emafutheni, kwesinye isikhathi igxishwa emafutheni. sterEster, ifomula ejwayelekile yamakhemikhali iRCOOR ′. I-Lanolin ne-beesw izembe liyizinhlanganisela zemvelo ze-ester, futhi futhi ziyizinto ezinhle zokuvala uphawu lwensimbi. Ama-ester ama-polyalcohols anemiphumela emihle yokulwa namagciwane, njenge-pentaerythrityl monooleate ne-sorbitan monooleate (Span-80), okuyizinto ezinhle zokulwa nezinsimbi futhi ezisetshenziswa kabanzi. (4) Ama-amines, ifomula ejwayelekile ingu-R-NH2, njenge-octadecylamine, njll. Noma kunjalo, ama-amine alula asetshenziswa kakhulu emafutheni amaminerali. Kodwa-ke, ama-amine alula awenele ukuvimbela ukugqwala emafutheni amaminerali, kepha ama-amine usawoti noma amanye ama-compounds akhiqizwa ama-amine nama-organic acid, njenge-octadecylamine oleate, i-cyclohexylamine stearate, njll. (5) isulfure, i-nitrogen heterocyclic compounds, izindandatho ze-heterocyclic eziqukethe isulfure noma i-nitrogen nokunye okutholakele, nazo zingcono i-rust inhibitors, njenge-imidazoline alkyl phosphate salt, i-benzotriazole ne-α-mercaptobenzothiazole nokunye. I-Imidazoline isetshenziselwa ukuvimbela ukugqwala kwensimbi okungeyona eyensimbi, kuyilapho i-benzotriazole isetshenziselwa kakhulu ithusi nokunye okungavimbeli ukugqwala kwensimbi.

Umenzeli we-antirust

Kunezinhlobo ezimbili ze-emulsified antirust agent: eyodwa ukumiswa kwezinhlayiya zikawoyela emanzini, okungukuthi u-oyela-emanzini-emulsion, okuvame ukuba mhlophe ubisi; okunye ukumiswa kwezinhlayiya zamanzi ku-oyela, okusho u-oyile-emanzini-emulsion, okuvame ukuba uketshezi olusobala noma olwehlayo. Umenzeli we-antirust we-emulsified akanakho nje ukusebenza kwe-antirust, kepha futhi nokuthambisa nokusebenza kokupholisa, ngakho-ke kuvame ukusetshenziselwa njengesipholisi sokuthambisa ukusika kwensimbi. Esikhathini esedlule, i-emulsifier ku-emulsified antirust agent isetshenziswa kakhulu kumafutha emifino kanye namafutha (njengamafutha yemifino, uwoyela we-castor, njll.) Ngenqubo ye-saponification, futhi ngekhulu lama-21, i-triethanolamine oleate, uwoyela we-sulfonated noma i-non-ionic surfactant kuyasetshenziswa. Ukuze uqinise ukusebenza okungavinjelwa ukugqwala, lapho uxubana ne-emulsion namanzi, inani elithile le-antirust agent encibilikiswa ngamanzi, njenge-sodium nitrite ne-sodium carbonate, i-sodium nitrite ne-triethanolamine nayo ingangezwa. Ngaphezu kwalokho, ukuze kuvinjelwe futhi kunciphise ukonakala kwe-emulsion, inani elincane lama-antifungal agents, njenge-phenol, i-pentachlorophenol, i-sodium benzoate, njll.
