Nov yog txhua yam koj yuav tsum paub txog tooj liab
Tooj liab yog ib qho kev hloov pauv, nrog rau cov cim tshuaj Cu, thiab cov lus Askiv lub npe tooj liab. Ntshiab tooj liab yog hlau mos. Thaum qhov saum npoo tsuas yog txiav, nws yog xim liab-txiv kab ntxwv nrog lub ntsiab lus ntawm cov xim hlau, thiab cov khoom ib leeg yog ntshav-liab. Nws muaj qhov zoo ductility, siab thermal conductivity thiab hluav taws xob conductivity, yog li nws yog cov khoom siv feem ntau hauv cov cables thiab cov khoom siv hluav taws xob thiab hluav taws xob. Nws tseem tuaj yeem siv los ua cov khoom siv hauv tsev thiab tuaj yeem tsim ntau hom alloys. Copper alloys muaj cov cuab yeej zoo heev thiab tsis tshua muaj kev tiv thaiv, ntawm cov tooj liab thiab tooj dag yog qhov tseem ceeb tshaj plaws. Tsis tas li ntawd, tooj liab kuj yog cov hlau ruaj khov uas tuaj yeem siv tau ntau zaus yam tsis muaj kev puas tsuaj rau nws cov khoom siv kho tshuab.
Cov khoom siv thiab cov yam ntxwv
Tooj liab yog cov hlau uas muaj nyob rau hauv lub ntiaj teb crust thiab dej hiav txwv. Cov ntsiab lus ntawm tooj liab nyob rau hauv lub ntiaj teb crust yog hais txog 0.01%, thiab nyob rau hauv ib co tooj liab deposits, cov ntsiab lus ntawm tooj liab yuav ncav cuag 3% mus rau 5%. Feem ntau ntawm cov tooj liab nyob rau hauv qhov muaj xws li cov tebchaw, uas yog tooj liab ores.
Tooj liab muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg xws li hluav taws xob conductivity, thermal conductivity, non-magnetic, corrosion resistance thiab ductility. Cov hluav taws xob conductivity thiab thermal conductivity yog thib ob tsuas yog nyiaj. Cov tooj liab ntshiab tuaj yeem kos rau hauv cov hlau zoo heev thiab ua rau hauv cov ntawv ci tooj liab heev. Cov ntu tshiab ntawm cov tooj liab ntshiab yog sawv liab, tab sis tom qab tooj liab oxide zaj duab xis yog tsim rau saum npoo, qhov tsos yog xim liab-liab, yog li nws feem ntau hu ua liab tooj liab.
1. Hluav taws xob conductivity thiab thermal conductivity: Tooj tooj hluav taws xob conductivity thiab thermal conductivity yog thib ob tsuas yog nyiaj. Thiab tus nqi qis dua li kub thiab nyiaj. Cov tooj liab ntshiab tuaj yeem kos rau hauv cov hlau zoo heev thiab ua rau hauv cov ntawv ci tooj liab heev.
2. Corrosion kuj: Feem ntau hais lus, tooj liab qhov corrosion kuj yog qis dua li cov kub, platinum, nyiaj thiab titanium, thaum kub, platinum thiab nyiaj yog cov hlau muaj txiaj ntsig thiab lawv cov ntawv thov tiag tiag yog me me; piv nrog cov hlau xws li hlau, zinc thiab magnesium, tooj liab muaj zog corrosion kuj. Piv nrog rau txhuas, tooj liab yog ntau resistant rau corrosion los ntawm non-oxidizing acids, alkalis thiab seawater, tab sis txhuas yog ntau resistant rau corrosion tshaj tooj liab nyob rau hauv cov huab cua, tsis muaj zog acid thiab lwm yam xov xwm.
3. Kev ua haujlwm yooj yim thiab kev sib sau: tooj liab muaj lub zog nruab nrab (200 ~ 360MPa), thiab nws cov deformation tsis kam yog ntau dua li ntawm txhuas tab sis tsawg dua li cov hlau thiab titanium. Copper muaj cov yas zoo thiab tuaj yeem tiv taus qhov loj ntawm kev kub thiab txias ua haujlwm, xws li dov, extrusion, forging, stretching, stamping, dabtsi yog khoov, thiab lwm yam. Lub deformation degree ntawm dov thiab ncab tuaj yeem ncav cuag ntau dua 95% yam tsis muaj qhov nruab nrab annealing thiab lwm yam. Kev kho cua sov.
4. Xim: Cov tooj liab ntshiab yog xim dawb thiab muaj kuab heev (tseem hu ua tooj liab), tooj liab alloys muaj ntau yam xim zoo nkauj, xws li golden daj (H65 tooj dag), nyiaj dawb (nickel nyiaj, zinc npib tsib xee), xiav (txhuas tooj liab, tin bronze), thiab lwm yam, uas yog gorgeous los yog meej mom thiab nrov heev.
5. Cov cuab yeej tiv thaiv kab mob: tooj liab tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob thiab lwm yam kab mob. 99% ntawm cov kab mob hauv dej yuav raug tua nyob rau hauv ib puag ncig tooj liab rau 5 teev. Qhov no tseem ceeb heev rau kev xa dej haus, khoom noj khoom haus, marine engineering, thiab lwm yam.
6. Weldability: tooj liab yog ib qho yooj yim rau welding los ntawm mos soldering, brazing, roj shielded arc vuam thiab lwm txoj kev. Phosphorus deoxidized tooj liab uas muaj ib qho me me ntawm phosphorus tau zoo dua weldability. Txij li thaum tooj liab muaj cov thermal conductivity zoo, tooj liab vuam yuav tsum muaj lub zog loj, lub zog loj ntawm cov nqaj hlau vuam, thiab nws yog qhov zoo tshaj plaws los siv kev tiv thaiv roj. Spot welding feem ntau tsis pom zoo.
7. Plating: tooj liab muaj cov khoom zoo plating. Nws tuaj yeem ua electroplated nrog high-melting point hlau xws li npib tsib xee thiab chromium, los yog kub-dip plated nrog tsawg-melting point hlau xws li tin thiab zinc.
Cov txheej txheem khoom thiab kev faib tawm
Cov zaub mov uas muaj tooj liab yog feem ntau, thiab feem ntau ntawm lawv muaj cov xim ci thiab qhov muag pom. Cov ore no tau ci hauv huab cua los ua tooj liab oxide CuO, thiab tom qab ntawd txo qis nrog cov pa roj carbon monoxide kom tau cov hlau tooj liab. Cov khoom ua los ntawm cov tooj liab ntshiab yog mos heev thiab yooj yim rau khoov. Cov neeg tau pom tias ntxiv tin rau tooj liab tuaj yeem ua rau tooj liab-tin alloy - bronze. Cov hlau ntawm tooj liab thiab kub tuaj yeem ua rau ntau yam ornaments thiab khoom siv. Ntxiv zinc ua rau tooj dag; ntxiv tin ua bronze.
1. Brass - tooj liab-zinc alloy. Cov xim hloov ntawm daj-liab mus rau daj ntseg daj raws li cov ntsiab lus zinc nce. Brass muaj cov khoom siv ntau dua li cov tooj liab ntshiab. Nws yuav tsis xeb lossis corrode nyob rau hauv ib txwm muaj xwm txheej. Nws muaj plasticity zoo thiab yog dav siv nyob rau hauv kev tsim machinery kev lag luam los ua ntau yam qauv.
2. Bronze - tooj liab-tin alloy (tshwj tsis yog zinc thiab npib tsib xee, tag nrho cov alloys nrog lwm cov ntsiab lus hu ua bronze). Nws muaj zoo hnav tsis kam, mechanical zog, casting zog thiab corrosion kuj. Cov ntsiab lus tin hauv cov hlau feem ntau tsis tshaj 10%, siab dhau yuav txo nws cov plasticity.
3. Cupronickel - tooj liab-nickel alloy. Nws tau muab faib ua cov qauv tooj liab-nickel alloy thiab hluav taws xob tooj liab-nickel alloy. Cov qauv tooj liab-nickel alloy muaj cov cuab yeej siv siab thiab zoo corrosion kuj. Hluav taws xob tooj liab-nickel alloy feem ntau muaj tshwj xeeb thermoelectric zog. Lub npe nrov muaj manganese tooj liab, constantan thiab tooj liab yog manganese cupronickel nrog cov ntsiab lus ntawm manganese sib txawv. Lawv yog cov khoom siv hluav taws xob tsis tseem ceeb rau kev tsim cov khoom siv hluav taws xob ntsuas hluav taws xob, rheostats, thermocouples, hluav taws xob cua sov, thiab lwm yam.
Tsim thiab installation nodes
Kev ua thiab siv tooj liab muaj keeb kwm ntau txhiab xyoo. Daim ntawv thov ntawm tooj liab hauv architecture tuaj yeem muab faib ua ob lub tshuab loj: tooj liab kos duab thiab cov khoom siv phab ntsa.
Copper art yog ib qho khoom siv zoo nkauj tooj liab kos duab, nrog rau cov qhov rooj tooj liab, cov duab thaij duab, cov tes tuav, thiab lwm yam hauv cov tsev. Cov khoom siv kho kom zoo nkauj no yog tsim los ntawm cov kws tshaj lij tooj liab kos duab. Nws tuaj yeem hais tias txhua daim muaj txiaj ntsig zoo nkauj heev.
Kev siv tooj liab kab hlau rhuav phab ntsa thiab ru tsev zoo ib yam li qee cov hlau xws li stainless hlau. Tseem muaj cov khoom xws li tooj liab-yas composite panels thiab cua honeycomb panels ntawm lub khw. Yog tias qhov kev xav tau ntawm qhov project tsis siab, ib txoj hauv kev yooj yim ntawm kev siv lub nraub qaum rov qab los yog galvanized steel phaj txhawb nqa tuaj yeem siv los txhim kho lub tiaj tus.
