C28000 tooj dag yog dab tsi?
C28000 yog ib hom tooj dag (tooj liab-zinc alloy) hauv American ASTM tus qauv, feem ntau hu ua "Muntz Gold" lossis "60-40 Brass". Cov hlau no muaj lub zog zoo, tawv, thiab corrosion kuj, nrog rau cov khoom siv hluav taws xob zoo thiab thermal conductivity, thiab yog li ntawd dav siv nyob rau hauv ntau yam xws li kev lag luam, kev tsim kho, tsheb, thiab marine engineering.

Nrog rau txhua xyoo muaj peev xwm ntawm kaum tawm txhiab tons, peb tuaj yeem hloov kho raws li kev txiav txim siab, kom ntseeg tau tias peb cov khoom ua tau raws li cov qauv thoob ntiaj teb hauv qhov raug qhov tseeb, cov khoom siv kho tshuab, thiab cov khoom tiav.
Copper khoom ntim
Peb siv cov txheej txheem ntim khoom raws li cov yam ntxwv ntawm cov khoom lag luam: cov raj tooj liab thiab cov pas nrig yog qhwv nrog cov dej noo-cov ntawv kraft resistant, ntxiv nrog cov bundling, thiab ruaj rau ntawm cov ntoo pallets lossis cov thawv hlau los tiv thaiv kev deformation thiab kev puas tsuaj thaum caij tsheb npav. Copper daim hlau thiab strips yog them nrog zaj duab xis tiv thaiv, sib cais los ntawm npuas padding ntawm cov khaubncaws sab nraud povtseg, thiab sab nraud ruaj nrog steel strapping nrog rau cov ntim dej tsis zoo. Cov hlau yog coiled ntawm cov reels muaj los yog lub tshuab nqus tsev- ntim nrog cov yas zaj duab xis. Tag nrho cov ntim khoom suav nrog cov ntawv qhia meej uas qhia txog cov khoom tshwj xeeb, cov lej batch, thiab cov cim tiv thaiv, ua kom muaj kev nyab xeeb thaum lub sijhawm ntev - kev thauj mus los hauv hiav txwv thiab av.
