Hais txog tooj liab

Toojyog ib qho ntawm cov hlau ntxov tshaj plaws uas tau pom thiab siv los ntawm tib neeg, ntshav-liab, lub ntiajteb txawj nqus 8.89, melting point 1083.4 ℃.Tooj thiab nws cov alloys tau dav siv vim lawv cov hluav taws xob zoo conductivity thiab thermal conductivity, muaj zog corrosion kuj, ua tau yooj yim, zoo tensile zog thiab qaug zog zog, thib ob tsuas yog steel thiab txhuas hauv cov khoom siv hlau, thiab tau dhau los ua cov ntaub ntawv tseem ceeb thiab cov tswv yim. cov ntaub ntawv nyob rau hauv lub teb chaws kev khwv nyiaj txiag thiab tib neeg txoj kev ua neej, lub teb chaws tiv thaiv tej yaam num thiab txawm high-tech teb.Nws yog dav siv nyob rau hauv hluav taws xob kev lag luam, machinery kev lag luam, tshuaj lom neeg kev lag luam, lub teb chaws tiv thaiv kev lag luam thiab lwm yam departments.Copper nplua hmoov yog ib qho kev mloog zoo ua los ntawm qib qis tooj liab-cov kabmob nyoos ore uas tau mus txog qee qhov kev ntsuas zoo los ntawm cov txheej txheem tau txais txiaj ntsig thiab tuaj yeem xa ncaj qha mus rau smelters rau tooj liab smelting.

tooj liab yog ib tug hnyav hlau, nws melting point yog 1083 degrees Celsius, boiling point yog 2310 degrees, ntshiab tooj liab yog liab doog.Copper hlau muaj hluav taws xob zoo thiab thermal conductivity, thiab nws cov hluav taws xob conductivity nyob qib thib ob hauv txhua cov hlau, thib ob tsuas yog nyiaj.Nws thermal conductivity nyob qib thib peb, thib ob rau nyiaj thiab kub.Cov tooj liab ntshiab yog qhov yooj yim heev, qhov loj ntawm cov dej ntws, tuaj yeem rub mus rau hauv 2,000 meter ntev filament, los yog dov rau hauv cov ntawv yuav luag pob tshab dav dua li lub txaj saum npoo.

 

"Dawb phosphor tooj liab plating" yuav tsum txhais tau tias "phosphor tooj liab nrog dawb txheej ntawm qhov chaw"."Dawb plating" thiab "phosphor tooj liab" yuav tsum to taub nyias.

Dawb plating -- Cov tsos xim ntawm txheej yog dawb.Cov khoom siv plating sib txawv lossis cov yeeb yaj kiab passivation txawv, cov tsos xim ntawm txheej kuj txawv.Phosphor tooj liab tinning rau cov khoom siv hluav taws xob yog dawb tsis muaj passivation.

 

Phosphorus tooj liab - tooj liab muaj phosphorus.Phosphorus tooj liab yog ib qho yooj yim rau solder thiab muaj elasticity zoo, thiab feem ntau yog siv rau hauv cov khoom siv hluav taws xob.

 

Liab toojyog tooj.Nws tau txais nws lub npe los ntawm nws cov xim liab.Saib tooj liab rau ntau yam khoom.

Liab tooj liab yog cov tooj liab ntshiab, nws cov ntsiab lus melting yog 1083 ° C, tsis muaj isomerism transformation, thiab nws cov txheeb ze ceev yog 8.9, tsib npaug ntawm magnesium.Kwv yees li 15% hnyav dua li cov hlau qub.Nws tau sawv liab, ntshav liab tom qab tsim oxide zaj duab xis rau saum npoo, yog li nws feem ntau hu ua tooj liab.Nws yog tooj liab uas muaj qee yam ntawm cov pa oxygen, yog li nws tseem hu ua oxygen-muaj tooj liab.

Liab tooj liab muaj npe rau nws cov xim liab liab.Nws tsis tas yuav ntshiab tooj liab, thiab qee zaum me me ntawm cov ntsiab lus deoxidation los yog lwm cov ntsiab lus ntxiv los txhim kho cov khoom siv thiab kev ua tau zoo, yog li nws kuj raug cais raws li tooj liab alloy.Suav cov khoom siv tooj liab tuaj yeem muab faib ua plaub pawg raws li muaj pes tsawg leeg: tooj liab zoo tib yam (T1, T2, T3, T4), tooj liab tsis muaj oxygen (TU1, TU2 thiab siab-purity, nqus pa tsis muaj tooj liab), deoxidized tooj liab (TUP , TUMn), thiab tshwj xeeb tooj liab (arsenic tooj liab, tellurium tooj liab, nyiaj tooj liab) nrog ib tug me me ntawm alloying ntsiab.Cov hluav taws xob thiab thermal conductivity ntawm tooj liab yog qhov thib ob tsuas yog nyiaj, thiab nws tau siv dav hauv kev tsim cov khoom siv hluav taws xob thiab thermal.Tooj liab nyob rau hauv cov huab cua, dej hiav txwv thiab ib co non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, ntsev tov thiab ntau yam organic acids (acetic acid, citric acid), muaj zoo corrosion kuj, siv nyob rau hauv kev lag luam tshuaj.Tsis tas li ntawd, tooj liab muaj qhov zoo weldability thiab tuaj yeem ua rau ntau yam khoom siv ua tiav thiab cov khoom tiav los ntawm kev ua haujlwm txias thiab thermoplastic.Hauv xyoo 1970, kev tsim cov tooj liab liab tau tshaj tag nrho cov khoom ntawm tag nrho lwm cov tooj liab alloys.
