CAS No. 37971-36-1

Molecular Formula: C₇H₁₁O₉P Molecular weight: 270.13

Cov qauv qauv:

Khoom:

PBTC muaj cov ntsiab lus tsis tshua muaj phosphoric, muaj cov yam ntxwv ntawm ob qho tib si phosphoric acid thiab carboxylic acid pab pawg, uas ua rau nws cov nplai zoo heev thiab kev tiv thaiv corrosion. Nws cov cuab yeej antiscale nyob rau hauv qhov kub thiab txias yog zoo dua li ntawm organophosphines. Nws tuaj yeem txhim kho zinc ntsev solubility, muaj cov tshuaj chlorine oxidation kam rau ua thiab zoo sib xyaw ua ke.

Kev siv:

PBTC yog ib tus neeg ua haujlwm siab zoo li nplai thiab corrosion inhibitor. PBTC yog qhov zoo tshaj plaws stabilizer rau zinc ntsev. Nws 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. PBTC tuaj yeem siv rau hauv cov xwm txheej kub, siab hardness, siab alkali thiab siab concentration index. Hauv lavation teb, nws yog siv los ua tus neeg sawv cev chelating thiab hlau detergent.

PBTC is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.

Ntim thiab khaws cia:

200L plastic drum,IBC(1000L),customers’ requirement. Storage for one year in shady room and dry place.

Kev nyab xeeb thiab kev tiv thaiv:

PBTC yog acidic, yog li kev sib cuag nrog lub qhov muag thiab tawv nqaij yuav tsum zam. Thaum nws txaws rau ntawm lub cev, yaug tam sim ntawd nrog dej ntau.
