tooj dag stripthiableaded tooj dag sawbyog ob qho tib si tooj liab alloy strips, qhov sib txawv tseem ceeb nyob hauv qhov muaj pes tsawg leeg, kev ua tau zoo thiab kev siv.
Ⅰ. Kev sib xyaw
1. Cov tooj dag yog tsim los ntawm tooj liab (Cu) thiab zinc (Zn), nrog rau qhov sib piv ntawm 60-90% tooj liab thiab 10-40% zinc. Cov qhab nia muaj xws li H62, H68, thiab lwm yam.
2. Leaded tooj dag yog tooj liab-zinc alloy nrog txhuas (Pb) ntxiv, thiab cov ntsiab lus txhuas feem ntau yog 1-3%. Ntxiv rau cov hmoov txhuas, nws kuj tseem muaj cov khoom me me, xws li hlau, npib tsib xee lossis tin, thiab lwm yam. Cov qib muaj xws li HPb59-1, HPb63-3, thiab lwm yam.
II. Cov yam ntxwv ua haujlwm
1. Mechanical zog
(1)tooj dag: Nrog kev hloov pauv ntawm zinc cov ntsiab lus, cov khoom siv kho tshuab sib txawv. Thaum cov ntsiab lus zinc tsis tshaj 32%, lub zog thiab plasticity nce nrog nce zinc cov ntsiab lus; Tom qab cov ntsiab lus zinc ntau dua 32%, cov yas poob qis, thiab lub zog nce mus txog qhov siab tshaj plaws nyob ze ntawm zinc cov ntsiab lus ntawm 45%.
(2)Lead tooj dag: Nws muaj lub zog zoo, thiab vim muaj cov hlau lead, nws hnav tsis kam zoo dua li cov tooj dag zoo tib yam.
2. Kev ua haujlwm zoo
(1)tooj dag: Nws muaj cov yas zoo thiab tuaj yeem tiv taus kub thiab txias ua haujlwm, tab sis nws yog nquag mus rau nruab nrab-kub brittleness thaum ua kub xws li forging, feem ntau ntawm 200-700 ℃
(2)Lead tooj dag: Nws muaj lub zog zoo, thiab vim muaj cov hlau lead, nws hnav tsis kam zoo dua li cov tooj dag zoo tib yam. Lub xeev dawb ntawm cov hlau lead ua rau nws ua lub luag haujlwm txo kev sib txhuam thaum lub sij hawm kev sib txhuam, uas tuaj yeem txo qhov hnav zoo.
3. Lub cev thiab tshuaj muaj zog
(1) Brass: Nws muaj cov khoom siv hluav taws xob zoo, thermal conductivity thiab corrosion kuj. Nws corrodes qeeb heev nyob rau hauv cov huab cua thiab tsis ceev heev nyob rau hauv cov dej ntshiab ntshiab, tab sis nws corrodes me ntsis sai dua nyob rau hauv seawater. Hauv cov dej uas muaj qee cov roj av lossis hauv cov cheeb tsam tshwj xeeb acid-puag, tus nqi corrosion yuav hloov.
(2) Leaded tooj dag: Nws cov hluav taws xob thiab thermal conductivity yog me ntsis qis dua tooj dag, tab sis nws cov corrosion kuj zoo ib yam li tooj dag. Hauv qee qhov chaw tshwj xeeb, vim muaj cov hmoov txhuas, nws cov kev tiv thaiv corrosion kuj tseem ceeb dua.
3. Cov ntawv thov
(1)tooj dag stripsmuaj ntau yam thiab tsim nyog rau ntau lub sijhawm, tshwj xeeb tshaj yog cov uas xav tau kev tsim qauv zoo thiab qhov chaw zoo.
1) Kev lag luam hluav taws xob thiab hluav taws xob: connectors, terminals, shielding npog, thiab lwm yam.
2) Architectural kho kom zoo nkauj: lub qhov rooj tuav, hniav strips, thiab lwm yam.
3) Kev tsim khoom siv: gaskets, springs, heat sinks, thiab lwm yam.
4) Cov khoom siv niaj hnub: zippers, khawm, thiab lwm yam.
(2)Lead tooj dag sawbmuaj kev ua tau zoo heev thiab tsim nyog rau precision machining, tab sis kev saib xyuas yuav tsum tau them rau ib puag ncig thiab kev noj qab haus huv ntawm cov hlau lead. Hauv cov dej haus thiab cov chaw uas muaj kev tiv thaiv ib puag ncig siab, nws raug nquahu kom siv cov hlau tsis muaj hlau lead.
1) Precision qhov chaw: saib qhov chaw, iav, li qub, thiab lwm yam.
2) Cov khoom siv hluav taws xob: high-precision connectors, terminals, thiab lwm yam.
3) Automotive kev lag luam: roj system qhov chaw, sensor vaj tse, thiab lwm yam.
