Qib Xaiv Tsav Txhua Qhov Kev Txiav Txim Siab
Daim ntawv tooj liab tsis yog ib qho khoom siv. Cov txheej txheem European tsim los ntawm EN 1412 cais cov qib los ntawm cov khoom seem uas tswj cov kev coj ua thiab los ntawm kev coj ua deoxidation uas txiav txim siab seb daim ntawv coj li cas thaum vuam thiab brazing. Yog li ntawd, xaiv ib qib yog thawj qhov kev txiav txim siab, thiab nws kho qhov kev ua tau zoo, kev tsim tus cwj pwm thiab kev sib koom ua ke.
| Qib | Yam ntxwv tseem ceeb | Hom conductivity |
|---|---|---|
| Cu-ETP (CW004A / C11000) | electrolytic tawv pitch, lub hom phiaj dav dav | txog 100 txog 101% IACS |
| Cu-OF (CW008A / C10200) | oxygen dawb, rau lub tshuab nqus tsev thiab hluav taws xob | txog 100 txog 101% IACS |
| Cu-DHP (CW024A / C12200) | phosphorus deoxidized, weldable thiab brazeable | kwv yees li 85% IACS |
| CuZn tooj dag | tus nqi-zoo, muaj zog, zoo nkauj | zoo hauv qab cov qib tooj liab ntshiab |
Daim ntawv, sawb, phaj thiab dov bar rau lub hom phiaj dav dav tau teev tseg rau ASTM B152 / B152M, thaum daim ntawv tooj liab thiab sawb rau kev siv lub tsev ua raws EN 1172. Suav ntau lawm feem ntau tau lees paub rau GB / T 2059 rau tooj liab thiab tooj liab alloy sawb. Kev hais ib qib tawm tsam tus qauv raug tshem tawm feem ntau ntawm qhov tsis meej pem los ntawm kev nug txog kev yuav khoom.
Conductivity, Temper thiab Thickness
Cov hluav taws xob conductivity yog hais nyob rau hauv % IACS, thiab thermal conductivity raws li nws ze ze ntawm kwv yees li 390 W / (m * K) rau siab - qib conductivity. Cov khoom siv hluav taws xob thiab hluav taws xob xa tawm xav tau cov duab siab tshaj plaws, thaum cov khoom siv dav dav tuaj yeem lees txais qhov qis qis ntawm cov qib deoxidised hauv kev sib pauv kom yooj yim dua vuam.
Temper tseem ceeb npaum li qib. TS EN 1173 Kev txiav txim siab lub zog tsim qauv, thiab qhov muag muag muag muab qhov siab tshaj plaws elongation rau kev sib sib zog nqus nqus thaum lub quarter nyuaj thiab ib nrab ntawm cov tawv tawv muab ntau qhov nruj thiab lub caij nplooj ntoos hlav. Thickness spans nyias daim ntawv mus rau lub phaj hnyav, thiab qhov dav thiab ntev yog xaiv los ntawm qhov loj me me kom cov khib nyiab pov tseg qis.
Daim ntawv thov: Hluav taws xob, Thermal thiab Architectural
Luam tawm Circuit Board substrates, busbars, davhlau ya nyob twg blocks thiab hluav taws xob tiv tauj siv high -conductivity ntawv vim hais tias txhua txhua qhov chaw ntawm kev tiv thaiv ua cua sov hauv kev pab cuam. Thaum tshav kub kub dab dej, daim hlau txias, induction coils thiab thermal spreaders siv tib yam khoom rau qhov opposite sab ntawm lub zog tshuav nyiaj li cas, tsiv tshav kub ntawm ib tug ntaus ntawv los yog faib nws tusyees.
Architectural ua hauj lwm siv tooj liab ntawv rau vov tsev, gutters, fascias thiab cladding. Cov huab cua ntog mus rau qhov ruaj khov patina thiab yuav tsum tsis muaj txheej, thiab cov khoom siv tib yam tuaj yeem raug soldered lossis brazed ntawm qhov chaw. Hniav vaj huam sib luag, kos npe thiab sab hauv hlau ua haujlwm siv polished thiab txhuam tiav qhov zoo li qhov yuav tsum tau ua.
Fabrication, sib koom thiab kev npaj nto
Annealed daim ntawv txiav tau yooj yim, cov ntaub ntawv tsis muaj cracking thiab yuav spun los yog nias rau complex duab. Soldering thiab brazing yog niaj hnub, thiab vuam yog qhov ua tau zoo nrog cov qib deoxidised vim tias cov ntsiab lus phosphorus inhibits qhov porosity uas oxygen - bearing tooj liab tuaj yeem txhim kho. Txhua qhov flux residue yuav tsum tau muab tshem tawm tom qab kev koom ua ke, vim tias cov dej ntws tawm yog ib qho ua rau tom qab corrosion thiab txheej tsis ua haujlwm.
Kev npaj deg ua ntej pleev xim los yog nplaum nplaum yuav tsum tawm ntawm qhov chaw huv si, maj mam abraded. Copper oxide cov ntaub ntawv sai sai hauv huab cua, yog li lub sijhawm nruab nrab ntawm kev npaj thiab kev sib txuas yog cov txheej txheem uas yuav tsum tau tswj tsis yog sab laug rau tus neeg teb xov tooj.
Ordering, Inspection thiab Delivery
Ib qho kev txiav txim yuav tsum sau npe rau qib, tus qauv, temper, thickness, dav, ntev thiab ntug mob, ua ke nrog rau tej yam conductivity los yog hardness yuav tsum tau yuav tsum tau xyuas rau ntawm daim ntawv tiav. Kev tshuaj xyuas cov khoom lag luam npog cov thickness ntawm ob peb lub ntsiab lus, flatness, defects thiab, qhov twg yuav tsum tau, tshuaj ntsuam xyuas thiab ntsuas conductivity.
Cov ntaub ntawv soj ntsuam tau muab tso rau hauv EN 10204 3.1 khi daim ntawv xa mus rau nws tus lej xov tooj cua sov thiab cov txiaj ntsig kev xeem, uas yog lub hauv paus siv tau rau kev taug qab hauv hluav taws xob, kev kho mob thiab siab- hais txog cov ntawv thov. Daim ntawv yog muab interleaved thiab ntug- tiv thaiv kom qhov chaw tuaj txog hauv qhov xwm txheej nws tau tshuaj xyuas hauv.
Cov lus nug nquag
Q: Cov ntawv tooj liab twg yuav tsum tau siv rau kev ua haujlwm hluav taws xob?
A: High-cov qib conductivity hauv Cu-ETP lossis Cu- ntawm cov tsev neeg yog qhov kev xaiv ib txwm muaj, txij li lawv mus txog 100% IACS thiab khaws cov cua sov kom tsawg.
Q: Thaum twg Cu-DHP qhov kev xaiv zoo dua?
A: Thaum qhov yuav tsum tau welded los yog brazed thiab embrittlement los ntawm yaj oxygen yog qhov txaus ntshai. Cov phosphorus ntxiv txo qis conductivity tab sis ua rau cov txheej txheem kev txhim khu kev qha.
Q: % IACS txhais tau li cas?
A: Nws qhia txog kev coj ua raws li feem pua ntawm cov txheej txheem thoob ntiaj teb annealed tooj liab, yog li daim duab siab dua txhais tau tias qis hluav taws xob tsis kam rau tib ntu ntu.
Q: Daim ntawv tooj liab puas tuaj yeem muab tau rau hauv ib qho kev kub ntxhov?
A: Yog. Mos annealed, peb lub hlis twg nyuaj, ib nrab nyuaj thiab nyuaj tempers yog tag nrho cov tsim, thiab lub temper designation system ntawm EN 1173 yog siv los qhia qhov yuav tsum tau kom meej meej.
Q: Daim ntawv tooj liab tiv thaiv li cas rau kev xa khoom?
A: Daim ntawv yog interleaved los yog zaj duab xis qhwv, stacked tiaj tus ntawm ib tug haum pallet thiab strapped kom cov npoo thiab nto tsis puas nyob rau hauv tuav.
