Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm C12200?
Qhov sib xyaw ntawm C12200 yog txhais los ntawm ASTM cov qauv, feem ntau ASTM B75, B88, B280, thiab lwm yam uas npog cov khoom sib txawv. Cov kev cai yog ncaj nraim: qhov no yog siab - purity tooj liab nrog me me tab sis tseem ceeb ntxiv ntawm phosphorus.
Ntawm no yog cov txheej txheem ib txwm:
| Element | Composition (los ntawm qhov hnyav) |
|---|---|
| Copper (nrog rau nyiaj) | 99.9% tsawg kawg nkaus |
| Phosphorus | 0.015% – 0.040% |
| Lwm yam khoom (tag nrho) | 0.1% siab tshaj |
Hauv kev xyaum, feem ntau cov mills tsim C12200 nrog cov ntsiab lus tooj liab zoo tshaj qhov tsawg kawg nkaus -feem ntau 99.95% lossis siab dua- thiab phosphorus ua tib zoo tswj nyob rau hauv qhov kev teev tseg.
Vim li cas Phosphorus Ntxiv?
Qhov sib ntxiv ntawm phosphorus pab ib lub hom phiaj tseem ceeb:deoxidation.
Thaum lub sij hawm refining tooj liab, ib qho me me ntawm oxygen yog ib txwm muaj. Hauv kev lag luam feem ntau qib tooj liab, cov pa oxygen no tseem nyob hauv cov khoom kawg. Piv txwv li, C11000 (electrolytic tawv pitch tooj liab) muaj 0.02% mus rau 0.04% oxygen.
Cov pa oxygen no dhau los ua teeb meem thaum tooj liab yog welded, brazed, los yog raug hydrogen ntawm qhov kub thiab txias. Cov pa oxygen reacts nrog hydrogen los ua dej vapor hauv cov hlau, ua rau sab hauv tawg thiab embrittlement -ib qho tshwm sim hu ua hydrogen embrittlement.
Thaum phosphorus ntxiv rau molten tooj liab, nws reacts nrog oxygen los tsim phosphorus pentoxide, uas ntab tawm ntawm cov yaj. Qhov tshwm sim yog tooj liab uas yog qhov tseem ceeb ntawm oxygen -dawb thiab tuaj yeem ruaj ntseg welded, brazed, thiab koom nrog yam tsis muaj kev pheej hmoo.
Cov phosphorus tseem tshuav hauv cov khoom kawg yog qhov seem me me -feem ntau 0.015% rau 0.040%- uas ua kom tiav deoxidation thaum muaj kev cuam tshuam tsawg rau lwm yam khoom.
