Hauv kev tsim khoom ntawm Din rail davhlau ya nyob twg thaiv, kev xaiv ntawm cov khoom siv kho vajtse cuam tshuam rau cov khoom lag luam. Ntawm cov khoom siv feem ntau, tooj dag, tooj liab liab, thiab hlau txhua tus muaj cov yam ntxwv tshwj xeeb uas cuam tshuam rau kev ua haujlwm ntawm cov ntsia hlau hom thiab lub caij nplooj ntoos hlav hom davhlau ya nyob twg.
Hluav taws xob conductivity
Liab tooj liab, paub txog nws cov khoom siv hluav taws xob zoo, yog qhov kev xaiv sab saum toj thaum txo qis hluav taws xob kuj tseem ceeb heev. Hauv cov ntawv thov siab - tam sim no, tooj liab liab - ua cov davhlau ya nyob twg tuaj yeem ua tau hluav taws xob zoo, txo cov hluav taws xob poob thiab tsim hluav taws xob. Piv txwv li, nyob rau hauv lub hwj chim faib tshuab nrog loj - tam sim no kis tau tus mob, liab tooj liab ntsia hlau hom davhlau ya nyob twg blocks kom ruaj khov thiab txhim khu kev qha hluav taws xob kev twb kev txuas.
tooj dag, ib qho alloy ntawm tooj liab thiab zinc, muaj qis hluav taws xob conductivity piv rau liab tooj liab. Txawm li cas los xij, nws tseem muaj kev coj ncaj ncees rau ntau yam kev siv hluav taws xob siv. Nws feem ntau yog siv nyob rau hauv lub davhlau ya nyob twg thaiv rau cov khoom siv hluav taws xob hauv tsev lossis qis - rau - nruab nrab tam sim no muaj kev tswj xyuas circuits.
Hlau, ntawm qhov tod tes, muaj cov hluav taws xob tsis zoo. Kev siv cov hlau hauv lub davhlau ya nyob twg rau lub hom phiaj kev sib txuas hluav taws xob yuav ua rau muaj kev tiv thaiv siab, kev tsim hluav taws xob ntau dhau, thiab muaj peev xwm txuas tsis tau, yog li nws tsis tshua muaj siv rau kev siv hluav taws xob ncaj qha hauv cov qauv dav hlau thaiv.
Mechanical Properties
Hlaumuaj zoo heev mechanical zog thiab hardness. Qhov no ua rau nws tsim nyog rau cov ntawv thov uas lub davhlau ya nyob twg thaiv yuav tsum tau tiv thaiv kev ntxhov siab tseem ceeb. Piv txwv li, nyob rau hauv qee qhov kev lag luam hnyav, steel - lub caij nplooj ntoo hlav hom davhlau ya nyob twg tuaj yeem tswj hwm lawv cov qauv kev ncaj ncees thaum muaj kev vibrations, cuam tshuam, lossis siab - torque fastening.
Brass kuj muaj cov khoom siv kho tshuab zoo, suav nrog lub zog nruab nrab thiab zoo malleability. Nws tuaj yeem tsim tau yooj yim rau hauv ntau yam duab thaum lub sij hawm tsim cov txheej txheem ntawm cov davhlau ya nyob twg. Qhov kev ua tau zoo no tso cai rau kev tsim cov txheej txheem dav dav dav dav, xws li cov neeg uas muaj lub ntsej muag zoo nkauj - zawm cov txheej txheem hauv cov ntsia hlau hom davhlau ya nyob twg.
Liab tooj liab, thaum muaj cov khoom siv hluav taws xob zoo, yog qhov muag muag piv rau tooj dag thiab hlau. Nyob rau hauv cov ntawv thov uas muaj kev ntxhov siab rau cov neeg kho tshuab siab, cov tooj liab liab lub davhlau ya nyob twg tuaj yeem ua rau deformation ntau dua. Txawm li cas los xij, qhov softness no tuaj yeem ua tau zoo dua hauv kev ua tiav cov hluav taws xob tiv thaiv zoo thaum tsim kom zoo.
Corrosion Resistance
Brass muaj corrosion kuj zoo dua li liab tooj liab vim muaj zinc nyob rau hauv nws muaj pes tsawg leeg. Nyob rau hauv cov huab cua ntub los yog corrosive, tooj dag - ua lub davhlau ya nyob twg thaiv tuaj yeem tiv taus oxidation thiab corrosion rau lub sijhawm ntev. Qhov no ua rau tooj dag yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv dav hlau siv hauv cov khoom siv hluav taws xob sab nraum zoov lossis hauv thaj chaw uas muaj av noo siab.
Liab tooj liab, txawm hais tias nws tuaj yeem tsim cov txheej txheem oxide tiv thaiv lub sijhawm, muaj kev cuam tshuam ntau dua rau corrosion hauv qee qhov acidic lossis alkaline ib puag ncig. Cov txheej txheem tshwj xeeb lossis kev kho mob feem ntau yuav tsum tau txhim kho nws cov kev tiv thaiv corrosion thaum siv hauv cov xwm txheej hnyav.
Hlau yog qhov cuam tshuam rau corrosion, tshwj xeeb tshaj yog nyob rau hauv lub xub ntiag ntawm noo noo thiab oxygen. Yog tsis muaj kev tiv thaiv corrosion zoo li galvanization los yog pleev xim, steel terminal blocks yuav sai sai xeb thiab degrade, ua rau tsis zoo hluav taws xob sib txuas thiab txo cov neeg kho tshuab lub zog.
Nyob rau hauv cov ntsiab lus, thaum xaiv cov ntaub ntawv rau Din rail davhlau ya nyob twg blocks, liab tooj liab yog zoo tagnrho rau siab - conductivity yuav tsum, tooj dag muaj ib tug sib npaug ntawm hluav taws xob thiab txhua yam khoom nrog rau zoo corrosion kuj rau cov kev siv dav dav, thiab steel yog tsuas yog siv thaum muaj zog mechanical zog yog thawj qhov kev txhawj xeeb, feem ntau nrog rau kev kho corrosion ntxiv.
