Khoom npe: 2-Phosphonobutane -1,2,4-Tricarboxylic Acid (PBTCA) 50%
Synonyms: PBTCA 50%
Qauv: C7H11O9P
CAS Nr .: 37971-36-1
Dej Kho Tshuaj PBTCA, zoo corrosion inhibitors, yog dav siv nyob rau hauv circulating dej txias system thiab oilfield dej txhaj system antifouling kev kho mob.
Kev Kho Dej Tshuaj PBTCA yog siv los ua cov tshuaj tiv thaiv corrosion rau kev kho dej. Cov khoom no muaj peev xwm ua tau zoo nrog Ca2 +, Zn2 +, Cu2 +, Mg2 +.
Qhov haum PH ntau yog los ntawm 7.0 txog 9.5. Nws tuaj yeem ua haujlwm ntawm qhov kub thiab txias, siab hardness, thiab siab alkalinity tej yam kev mob. Nws tso cai rau cov dej txias kom ntau ntxiv rau xya lossis ntau dua.
(1) Raws li tus neeg sawv cev muaj txiaj ntsig zoo ntawm nplai thiab kev tiv thaiv corrosion, PBTC yog ib qho ntawm cov khoom siv dav siv thiab ua tau zoo.
(2) PBTC yog qhov zoo tshaj plaws stabilizer rau zinc ntsev. PBTC yog dav siv nyob rau hauv circulating dej txias system thiab oilfield refill dej system raws li teev thiab corrosion inhibitor, haum rau composite nrog zinc ntsev thiab copolymer.
(3) Nws tuaj yeem siv rau hauv cov xwm txheej kub, siab hardness, siab alkali thiab siab concentration Performance index.
(4) Hauv lavation teb, nws yog siv los ua tus neeg sawv cev chelating thiab hlau detergent.
