ASTM B111 tooj liab yeeb nkab PDF
sB111 C44300 tooj liab yog dab tsi?
sB111 C44300 tooj liab alloy yog arsenic -inhibited tooj liab-zinc-tin alloy, feem ntau hu ua arsenic-inhibited naval hlau los yog naval tooj dag. Nws ua ke lub zog thiab ductility nrog zoo corrosion kuj. Qhov sib ntxiv ntawm ib qho me me ntawm arsenic (nominal cov ntsiab lus 0.06%) yog txhawm rau txo cov hlau tsis muaj zog rau dezincification thiab kev ntxhov siab corrosion. Nws yog dav siv nyob rau hauv condenser, evaporator, thiab tshav kub exchanger tubing thiab lwm yam kev siv.
Tshuaj Txhaum Cai
Tus qauv tshuaj muaj pes tsawg leeg rau Admiralty Brass C44300 rau ASTM B111:
| Element | Kev sib xyaw (%) | Lub luag haujlwm hauv Alloy |
| Copper (Cu) | 70.0 – 73.0 | Lub alloy lub hauv paus muab zoo heev thermal conductivity. |
| Tin (Sn) | 0.9 – 1.2 | Tus thawj inhibitor tiv thaiv dezincification. |
| Arsenic (As) | 0.02 – 0.06 | Secondary inhibitor rau ntxiv stability. |
| Lead (Pb) | Max 0.07 | Ib qho impurity txwv kom muaj kev ncaj ncees ntawm cov khoom. |
| Hlau (Fe) | Max 0.06 | Ib qho impurity tswj rau siab corrosion kuj. |
| Zinc (Zn) | Tshuav | Muab mechanical zog thiab hardness. |
Lub luag haujlwm ntawm Inhibitors
Tin thiab arsenic yog dab tsi ua rau Admiralty Brass tshwj xeeb.
Tin (Sn):
Nyob rau hauv cov dej corrosive tin tsim ib tug ruaj tsis- ntxeem tau thiab nws tus kheej- kho zaj duab xis ntawm stannic oxide nyob rau saum npoo. Qhov kev thaiv no tiv thaiv cov electrolyte los ntawm leaching zinc los ntawm alloy matrix.
Arsenic (As):
Raws li tus thib ob inhibitor arsenic muab ib txheej ntxiv ntawm kev tiv thaiv kom ntseeg tau ntev -lub sij hawm stability.
