Raws li ib qho tseem ceeb ntawm cov tub ntxhais sib txuas hauv cov kav dej, qhov sib npaug ntawm txoj kab nruab nrab sab hauv cov hlau lub luj tshib ua lub luag haujlwm tseem ceeb hauv kev hloov cov kua dej ntws thiab ua kom cov kav dej ntws zoo. Peb cov khoom yog ua los ntawm high- tooj dag HPb59-1 zoo li lub substrate thiab ua tiav nrog precision npib tsib xee plating tshuab. Nws muaj cov qauv kev ruaj ntseg, kev tiv thaiv corrosion, hnav tsis kam, thiab zoo nkauj, thiab yog dav haum rau ntau yam kev lag luam thiab pej xeem cov xwm txheej, muab kev sib txuas txhim khu kev qha rau cov kav dej.
Cov khoom siv tseem ceeb: Kev ua tau zoo ntawm tooj dag HPb59-1
Cov khoom lag luam yog tsim los ntawm kev lag luam pom zoo siab -zoo dawb txiav tooj dag HPb59-1, nruj me ntsis ua raws li GB/T 5231 thiab GB/T 4423-2007 tus qauv. Nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab tau raug tswj xyuas kom ntseeg tau tias txhua yam khoom muaj cov khoom zoo heev.
Hais txog kev muaj pes tsawg leeg, HPb59-1 yog raws li 57.0% -60.0% tooj liab, nrog 38% -41% zinc los kho lub zog thiab plasticity, thiab 0.8% -1.9% txhuas ntxiv los ua ib lub xeev pub dawb faib ntawm cov ciam teb. Qhov no tsis tsuas yog txhim kho kev ua tau zoo ntawm kev txiav, tab sis kuj ua rau cov khoom siv nrog cov khoom zoo ntawm tus kheej lubricating, txo cov kev sib txhuam poob tom qab kev sib txuas ntawm cov kav dej. Nyob rau tib lub sijhawm, nruj me ntsis tswj cov ntsiab lus hlau kom tsawg dua lossis sib npaug li 0.5% thiab tag nrho cov nyiaj ntawm lwm yam impurities yuav tsum tsawg dua lossis sib npaug li 0.2%, ua haujlwm kom ntseeg tau tias cov khoom sib xws thiab corrosion kuj ntawm cov khoom.
Hais txog cov khoom siv kho tshuab, lub zog tensile ntawm cov khoom no tuaj yeem ncav cuag 350-500MPa, thiab nws tuaj yeem tshaj 600MPa tom qab ua haujlwm txias. Lub elongation tus nqi yog tswj ntawm 15% -25%, thiab nws muaj peev xwm compressive zoo thiab yas deformation. Nws tuaj yeem hloov mus rau qhov kev hloov pauv siab nyob rau hauv kev ua haujlwm sib txawv thiab zam kev puas tsuaj rau cov kav dej sib txuas vim muaj kev ntxhov siab tsis sib xws. Tsis tas li ntawd, nws qhov ceev yog 8.5-8.7 g / cm³, uas yog qhov tsim nyog rau kev tsim qauv piv rau cov tooj liab ntshiab, thiab nws cov conductivity nce mus txog 28% -32% IACS, ua rau nws tsim nyog rau cov xwm txheej ntawm cov kav dej uas yuav tsum tau coj mus rau hauv tus account.
