Cov txheej txheem ntawm cov pas nrig tooj liab pib nrog kev ua tib zoo xaiv cov khoom siv tooj liab uas tsim nyog. Cov tooj liab yog melted thiab poured rau hauv ib lub bar, uas yog txias thiab txiav mus rau hauv ntau tswj lengths. Cov tuav no yog rhuab rau hauv qhov cub thiab extruded los ntawm ib tug hlau tuag. Cov txheej txheem no yog hu ua txias extrusion, thiab ua rau tooj liab rods zoo thiab lub zog.
Muaj ntau qhov zoo rau kev siv tooj liab rods piv rau lwm cov ntaub ntawv. Ua ntej, tooj liab yog ib qho zoo heev conductor ntawm hluav taws xob thiab cua sov, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hluav taws xob thiab hluav taws xob. Copper rods kuj yog corrosion resistant thiab muaj lub neej ntev, ua rau lawv zoo tagnrho rau siv nyob rau hauv hnyav ib puag ncig.
Tsis tas li ntawd, tooj liab yog cov khoom siv rov ua dua tshiab thiab ruaj khov. Cov pas nrig tooj liab tuaj yeem siv tau yooj yim thiab siv dua hauv kev tsim cov khoom tshiab. Recycling tooj liab kuj tseem muaj txiaj ntsig zoo rau ib puag ncig, vim tias nws txo qis cov khoom pov tseg thiab tshem tawm cov peev txheej tshiab.
Lwm qhov txiaj ntsig tseem ceeb ntawm cov pas nrig tooj liab yog lawv qhov kev ua tau zoo. Copper yog cov khoom muag muag, uas tuaj yeem ua rau cov duab sib txawv thiab ntau thiab tsawg. Qhov no ua rau nws zoo tagnrho rau kev siv hauv kev tsim kho, qhov twg nws yog siv hauv cov kav dej, cov kav dej sib txuas thiab cov cua sov.
