CAS No. 37971-36-1

Molecular Formula: C₇H₁₁O₉P Molecular weight: 270.13

Ifomula yoLwakhiwo:

Iinkcazelo ngeempawu:

PBTC inomxholo ophantsi wephosphoric, ineempawu zesakhiwo zazo zombini i-asidi ye-phosphoric kunye neqela le-carboxylic acid, eyenza isikali sayo esigqwesileyo kunye neempawu zokuthintela ukubola. Ipropathi yayo ye-antiscale phantsi kobushushu obuphezulu ingcono kakhulu kune-organophosphines. Inokuphucula ukunyibilika kwetyuwa ye-zinc, inokunyamezela okulungileyo kwe-chlorine oxidation kunye ne-synergy edibeneyo edibeneyo.

Inkcazo:

Izinto	Isalathiso
Imbonakalo	Ulwelo olungenambala okanye olutyheli olukhanyayo
Active acid, %	50.0 imiz
I-asidi ye-phosphorus (njenge-PO₃^3-), %	0.5 ubuninzi
I-asidi ye-Phosphoric (njenge-PO₄^3-), %	0.2 ubuninzi
Ubuninzi (20℃), g/cm³	1.27 min
pH(1% isisombululo samanzi)	1.5~2.0
Ewe, ppm	10.0 ubuninzi
I-chloride, ppm	10.0 ubuninzi

Ukusetyenziswa:

PBTC i-arhente esebenza kakuhle njengomlinganiselo kunye ne-corrosion inhibitor. PBTC yeyona nto ibalaseleyo yokuzinzisa ityuwa yezinki. Isetyenziswa ngokubanzi ekujikelezeni inkqubo yamanzi apholileyo kunye nenkqubo ye-oilfield yokuzalisa kwakhona amanzi njenge-scale kunye ne-corrosion inhibitor, efanelekileyo ukuhlanganisa kunye netyuwa ye-zinc kunye ne-copolymer. PBTC ingasetyenziselwa kwiimeko zokushisa okuphezulu, ubunzima obuphezulu, i-alkali ephezulu kunye nesalathisi esiphezulu soxinzelelo. Kwiindawo zokuhlambela, isetyenziswa njenge-agent ye-chelating kunye ne-detergent yesinyithi.

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.
