Xaiv cov tooj dag uas tsim nyog rau koj qhov project yuav tsum xav txog ntau yam. Hauv qab no yog ob peb yam cuam tshuam rau kev xaiv cov khoom siv rau koj siv.
Kev ua haujlwm ib puag ncig
Qhov no suav nrog qhov kub thiab txias, hom load, thiab corrosion tej yam kev mob. Piv txwv li, tus qauv tooj dag tuaj yeem muag los yog nkag rau ntawm qhov kub thiab txias. Nyob rau hauv ammonia los yog siab - ib puag ncig kev ntxhov siab, ceev faj rau kev ntxhov siab corrosion cracking (SCC), yuav tsum tau tshwj xeeb tooj dag alloys tsim los tiv thaiv tej yam kev mob.
Lub zog thiab hnav tsis kam
Txij li thaum lub zog ntawm tooj dag alloys yog nyob ntawm qhov txias ua hauj lwm hardening, txawm tias tib cov ntaub ntawv qhia txog kev ua tau zoo sib txawv hauv cov xwm txheej sib txawv. Piv txwv li, H62 (mos mob) thiab H62 (qhov mob hnyav) yog cov khoom sib txawv rau kev siv engineering, yuav tsum tau ua tib zoo xav thaum xaiv. Tsis tas li ntawd, rau cov haujlwm uas cuam tshuam nrog kev txav mus los (cov kabmob, lub zog, thiab lwm yam), kev ntsuas cov khoom siv zog ib leeg tsis txaus; hnav kuj yuav tsum tau soj ntsuam. Feem ntau, siab - lub zog tooj dag (manganese tooj dag, txhuas tooj dag, thiab lwm yam) muaj kev hnav zoo dua vim lawv cov khoom sib xyaw ua ke nyuaj, thaum cov hlau lead ua tau zoo dua rau tus kheej -lubricating zog.
Weldability
Vuam kev ua tau zoo yog qhov tseem ceeb thaum xaiv tooj dag rau tej yaam num. Feem ntau, cov ntsiab lus zinc ntau dua cuam tshuam nrog cov weldability tsis zoo. Yog li ntawd, yog tias vuam yuav tsum tau rau koj qhov project, tsawg-zinc tooj dag yog pom zoo, los yog xav txog brazing es tsis txhob fusion welding, raws li cov qauv no ua rau cov khoom degradation tsawg.
Machinability thiab Formability
Txawm hais tias tooj dag alloys feem ntau muab cov machinability zoo thiab formability, qhov zoo tshaj plaws alloys txawv nyob ntawm seb qhov yuav tsum tau ua. Rau qhov nyuaj peb- qhov sib txawv xws li cov leeg khoov lossis cov plhaub sib sib zog nqus, H68 lossis H80 nrog kev ua kom txias txias yog qhov kev xaiv zoo tshaj. Rau cov txheej txheem loj nrog cov duab zoo sib xws, H59 lossis cam khwb cia tooj dag, paub txog qhov zoo tshaj plaws kub formability, yog qhov zoo dua.
Nqi
Tus nqi yog qhov tseem ceeb tshaj plaws rau kev txiav txim siab thaum pib qhov project. Rau tooj dag, txij li tus nqi tooj liab feem ntau yog 3-4 npaug ntawm zinc, qhov hloov pauv ntawm tus nqi tooj liab cuam tshuam rau cov nqi tooj liab. Yog li ntawd, muab kev ua tau zoo raws li qhov yuav tsum tau ua, xaiv - dual- theem tooj dag (siab zinc) feem ntau yog kev lag luam ntau dua li ib zaug - theem tooj dag (tsis tshua muaj zinc). Rau cov brasses tshwj xeeb, cov ntsiab lus alloying feem ntau kim dua tooj liab lossis zinc lossis tam sim no muaj kev sib tw ntau dua. Lead (Pb), uas tsis tshua muaj nqi-tus nqi thiab txhim kho kev ua haujlwm ntawm tooj dag, feem ntau hu ua tus nqi-kev ua tau zoo. Txawm li cas los xij, nws cov kev txhawj xeeb txog kev nyab xeeb cuam tshuam tau ua tib zoo xav txog. Hloov pauv, cov ntsiab lus zoo li tin (Sn), npib tsib xee (Ni), thiab bismuth (Bi) hais kom tus nqi deb tshaj cov hlau lead (Pb). Tshwj xeeb, bismuth (siv los hloov cov hlau lead hauv kev tsim cov hlau lead- dawb tooj dag) ua rau tus nqi ntawm cov hlau tsis muaj hlau lead.
FAQ
Qhov txawv ntawm tooj liab, tooj dag, thiab Bronze yog dab tsi?
tooj liab, tooj dag, thiab tooj liab yog tag nrho hu ua "liab hlau." Lawv qhov tseem ceeb tshaj qhov sib txawv yog nyob rau hauv lawv cov muaj pes tsawg leeg. Tooj liab feem ntau yog 100% ntshiab tooj liab, tooj dag yog zinc - tooj liab alloy, thaum tooj liab yog tin - tooj liab alloy. Yog tias koj xav kawm ntxiv txog qhov zoo sib xws thiab qhov sib txawv ntawm peb, nyem "Brass vs Bronze vs Copper, Qhov txawv yog dab tsi?"
Dab tsi yog tooj dag alloys zoo tshaj plaws rau kev nqis peev casting?
Kev nqis peev casting ua tau zoo ntawm kev tsim cov castings nrog cov ntsiab lus zoo. Yog li ntawd, silicon bronze alloys nrog zoo heev fluidity uas muaj peev xwm tsim intricate nta (xws li C87500) thiab lead- liab tooj liab alloys nrog zoo machinability thiab siab sealing zog (xws li C83600) yog ob qho tib si kev xaiv zoo heev.
Dab tsi yog "Dezincification" thiab kuv tuaj yeem tiv thaiv nws li cas hauv kuv cov khoom tooj dag?
Dezincification corrosion yog ib qho tshwj xeeb "xaiv corrosion tshwm sim" tshwj xeeb rau tooj dag. Thaum lub sijhawm txheej txheem no, zinc maj mam leaches tawm ntawm tooj dag alloy, hloov cov tooj liab tawv tawv tawv rau hauv xoob, ntxeem tau "tooj liab pob txha" nrog lub zog tsis tshua muaj zog. Qhov kev xeb no feem ntau nce los ntawm qhov chaw sab hauv, lub ntsiab lus sab nraud ntawm qhov yuav pom tsis muaj qhov hloov pauv, tab sis nws sab hauv tau dhau los ua tsis yooj yim li daim txhuam cev, ua rau muaj kev pheej hmoo siab.
Txhawm rau tiv thaiv dezincification corrosion, tooj dag alloys nrog qis zinc cov ntsiab lus tuaj yeem xaiv yam tsis muaj kev cuam tshuam cov khoom siv, vim tias lawv muaj qhov tsis zoo rau dezincification. Tsis tas li ntawd, cov kev daws teeb meem tseem ceeb tam sim no suav nrog ntxiv cov lej ntawm cov khoom inhibitor xws li arsenic (As) lossis tin (Sn) rau tooj dag. Xwb, koj tuaj yeem xaiv cov qib tooj dag ncaj qha sau "Dezincification Resistant" (DZR), txawm hais tias cov no muaj nqi ntau dua.
Puas muaj cov hlau lead- cov kev xaiv tooj liab dawb rau feem ntau cov ntawv thov?
Yog lawm, nrog kev txhim kho thev naus laus zis thiab kev paub txog ib puag ncig, ntau yam sib npaug ntawm cov hlau lead tau tshwm sim. Piv txwv xws li txhuas- dawb silicon tooj dag (C87600) thiab bismuth tooj dag.
