cov khoom siv kaus mom yog C12200 tooj liab

1. Cov khoom siv dab tsi yog C12200?

C12200 yog aphosphorus -deoxidized ntshiab tooj liab(unalloyed tooj liab) cais raws li ASTM B152 tus qauv (American Society for Testing and Materials). Nws yog dav lees paub tias yog "deoxidized siab-conductivity (DHC) tooj liab" vim nws cov yam ntxwv tseem ceeb:

Tsis zoo li cov pa oxygen-cov kabmob tooj liab (xws li, C10200) lossis oxygen- tooj liab dawb (xws li, C11000), C12200 yog deoxidized nrog phosphorus thaum lub sijhawm tsim khoom kom txo qis cov ntsiab lus oxygen (feem ntau<0.001%).

Nws khaws cov hluav taws xob thiab thermal conductivity thaum txhim kho weldability thiab brazability - tseem ceeb rau cov ntawv thov uas yuav tsum tau koom nrog cov txheej txheem (piv txwv li, vuam, soldering).

Cov yam ntxwv tseem ceeb: Kev ua haujlwm zoo heev, zoo corrosion kuj nyob rau hauv uas tsis yog - nruj ib puag ncig, thiab compatibility nrog txias / kub ua hauj lwm (xws li, dov, extrusion, forging).

Kev siv cov xwm txheej: Cov kav dej fittings, cov kav dej kub sib txawv, cov vuam electrodes, cov khoom siv hluav taws xob, thiab cov kav dej muaj cov kav dej uas yuav tsum tau siv vuam lossis brazing.

2. Qhov xim ntawm C12200 yog dab tsi?

Cov xim saum npoo ntawm C12200 sib haum nrog cov yam ntxwv xim ntawm cov tooj liab ntshiab, nrog kev hloov pauv raws li qhov xwm txheej thiab ib puag ncig raug:

Tshiab / Polished nto: Ci ntsa iab -txiv kab ntxwv (tseem hu ua "tooj liab liab"), zoo ib yam rau lwm cov qib tooj liab ntshiab (xws li, C11000, T2). Qhov no yog lub ntuj xim ntawm siab -purity tooj liab ua ntej oxidation.

Tarnished Nto: Thaum lub sij hawm dhau mus, raug huab cua, noo noo, thiab carbon dioxide ua rau tsim cov patina nyias (tooj liab carbonate hydroxide, Cu₂(OH)₂CO₃). Cov xim maj mam hloov los ntawm reddish-txiv kab ntxwv mus rau tsaus xim av, thiab thaum kawg mus rau ib tug yam ntxwv greenish-xiav (verdigris) nrog ntev raug.

Thaum tshav kub kub{0}}Kho/welded nto: Tom qab kev kho cua sov los yog vuam, qhov saum npoo yuav tig xim liab los yog xim av vim yog oxidation ib ntus, tab sis qhov no tuaj yeem rov qab los rau qhov ci liab - xim txiv kab ntxwv los ntawm polishing lossis ntxuav.

Lus Cim: Cov ntsiab lus phosphorus hauv C12200 tsis hloov nws lub hauv paus xim - nws cov tsos zoo ib yam nrog cov tooj liab ntshiab.

3. Cov tshuaj muaj pes tsawg leeg ntawm C12200 yog dab tsi?

Raws li ASTM B152 tus qauv, cov tshuaj muaj pes tsawg leeg ntawm C12200 yog nruj me ntsis tswj, nrog siab tooj liab purity thiab tswj qib ntawm phosphorus (rau deoxidation) thiab impurities. Cov khoom tseem ceeb yog raws li nram no (los ntawm qhov hnyav feem pua):

Element	Cov ntsiab lus ntau yam (%)	Lub hom phiaj/Notes
Copper (Cu)	Ntau dua lossis sib npaug li 99.90%	Base hlau; Ua kom muaj hluav taws xob / thermal conductivity thiab ductility.
Phosphorus (P)	0.015–0.040%	Deoxidizing tus neeg sawv cev; txo cov ntsiab lus oxygen los tiv thaiv embrittlement thaum vuam.
Cov pa oxygen (O)	Tsawg dua lossis sib npaug li 0.001%	Tsawg kawg ntawm phosphorus deoxidation; zam "hydrogen embrittlement" nyob rau hauv siab -kub ib puag ncig.
Hlau (Fe)	Tsawg dua lossis sib npaug li 0.05%	Qhov siab tshaj plaws impurity; ntau hlau degrades conductivity thiab ductility.
Lead (Pb)	Tsawg dua lossis sib npaug li 0.005%	Kuaj impurity; tswj los xyuas kom meej machinability thiab corrosion kuj.
Sulfur (S)	Tsawg dua lossis sib npaug li 0.005%	Kuaj impurity; minimized los tiv thaiv brittle puas thiab txo corrosion.
Zinc (Zn)	Tsawg dua lossis sib npaug li 0.05%	Kuaj impurity; tsis txhob txwm siab ntxiv.
Lwm yam Impurities tag nrho	Tsawg dua lossis sib npaug li 0.10%	Cov ntsiab lus ntawm tag nrho lwm yam kab kawm (xws li, npib tsib xee, tin, txhuas) tsis tau teev saum toj no.

Qhov no muaj pes tsawg leeg sib npaug conductivity, weldability, thiab structural stability, ua C12200 haum rau industrial daim ntaub ntawv uas yuav tsum tau ob qho tib si kev ua tau zoo thiab kev koom tes muaj peev xwm.
