1. Qib txhais
TP2 yog Suav lub npe (GB/T 5231) rau UNS C12200 - phosphorus-deoxidized tooj liab nrog siab residual phosphorus (DHP). Thaum yaj, kwv yees li 0.015-0.04% phosphorus ntxiv kom tshem tawm cov pa oxygen; cov phosphorus residual txhim kho weldability thiab tshem tawm cov hydrogen - teeb meem embrittlement uas tshwm sim nyob rau hauv oxygen-bearing tooj liab (xws li T2 / C11000) thaum welded los yog brazed nyob rau hauv txo cov cua.
2. Tshuaj muaj pes tsawg leeg
| Lub ntsiab | txwv |
|---|---|
| Cu + Ag | Ntau dua lossis sib npaug li 99.90% |
| P | 0.015-0.040% |
3. Khoom
Hluav taws xob conductivity txog 80-85% IACS (annealed) - me ntsis hauv qab TP1/C12000, tseem txaus rau cov cua sov hloov thiab cov tub yees kab;
zoo thermal conductivity - kub zoo heev- pauv kev ua tau zoo;
weldability zoo heev thiab txias -bending zog; tsis muaj hydrogen-embrittlement tendency;
zoo corrosion kuj tiv thaiv ntau yam tshuaj; kev ua haujlwm ruaj khov nyob rau lub sijhawm;
raug annealed tensile 205-260 MPa nrog siab ductility rau coiling thiab sib sau.
4. Ntau lawm thiab zoo
Kev tsim cov kauj ruam: melting → nruam casting → extrusion → txias → kev kho cua sov (annealing), nrog rau cov txheej txheem nruj tswj thiab kev soj ntsuam zoo (chemistry, mechanical, eddy-tam sim no) kom ruaj khov.
5. Cov ntawv thov
Cov tub yees thiab huab cua- txias (cov kav dej tub yees, cov kav dej xau), roj av lossis roj xa mus, cov kav dej, condenser thiab cua sov- cov raj xa dej, thiab cov kav dej dav dav.
6. Kev txwv
Nyob rau hauv ib puag ncig oxidizing muaj zog qhov kev ua tau zoo ntawm TP2 yuav raug cuam tshuam - soj ntsuam daim ntawv thov ib puag ncig thiab kev pabcuam ua ntej xaiv.
