Tooj liab yog cov hlau ntshiab thiab ib qho khoom siv ib leeg, txhua yam khoom ua los ntawm tooj liab ua rau muaj kev nthuav tawm cov khoom qub tib yam. Ntawm qhov tod tes, tooj dag yog ib qho zoo nkauj ntawm tooj liab, zinc, thiab lwm yam hlau. Kev sib xyaw ua ke ntawm ntau cov hlau txhais tau tias tsis muaj txoj hauv kev ruam ib txwm los txheeb xyuas txhua tus brass. Txawm li cas los xij, peb yuav sib tham txog txoj hauv kev ntawm yuav ua li cas rau tooj liab txawv los ntawm tooj liab. Cov hau kev no tau hais tseg hauv qab no:
● Cov cim xim
Ntxuav ob qho kev hlau ua kom sib txawv. Ob qho tooj liab thiab tooj dag zog muaj patina nrog lub sijhawm. Qhov no Patina feem ntau yog greenish. Nyob rau hauv ib qho xwm txheej uas cov qub hlau yog pom, sim cov txheej txheem huv ntawm tooj liab. Thaum cov txheej txheem no ua haujlwm rau ob qho tib si hlau, siv tooj liab thiab tooj dag tu cov khoom kom nyob sab nraud.
Muab cov hlau tso rau hauv qab dawb. Hauv qhov no, yog tias cov hlau yuav raug txheeb tau polished, ces cuav lub teeb yuav pom tias ntawm kev xav lub teeb. Lwm txoj hauv kev mus ncig qhov no yog los ntawm saib nws hauv qab lub teeb lub teeb liab dawb fluorescent lossis tshav ntuj. Rau kev paub txog kev paub thov zam qhov daj incandescent bembivescence.
Txheeb xyuas cov xim liab ntawm tooj liab. Nws yog cov hlau ntshiab nrog lub ntsej muag liab-xim av.
Tshawb xyuas cov tooj daj daj. Tooj dag yog ua los ntawm tooj liab thiab zinc. Cov sib txawv ntawm cov nqi ntawm zinc hauv tooj liab ua cov xim sib txawv. Feem ntau, cov brass ib txwm siv ua tau pom cov xim daj lossis xim daj-xim av uas zoo ib yam li tooj dag. Lwm hom tooj dag yog Greenish-daj rau hauv tsos, thaum no alloy yog hu ua "gilding hlau". Nws muaj tsawg cov ntawv thov nyob rau hauv cov mos txwv thiab dai kom zoo nkauj.
Tshawb xyuas cov xim liab lossis cov txiv kab ntxwv tooj dag. Thaum tooj dag alloy hlau yog tsim los ntawm tsawg kawg yog 85% tooj liab, nws yuav saib liab-xim av lossis txiv kab ntxwv. Hom tooj daj no yog siv feem ntau hauv cov khoom dai kom zoo nkauj, cov hniav nyiaj hniav kub, thiab kav dej. Yog li, ib qho hint ntawm daj, txiv kab ntxwv, lossis kub xim denictions cov hlau yog tooj dag thiab tsis tooj liab.
Qhia lwm tus tooj dag. High Zinc ntsiab lus tooj dag tuaj yeem saib cov kub kaj, dawb, grey, lossis daj daj-dawb. Cov alloys hauv cov pawg no tsis nquag txij li lawv tsis yog machinable. Txawm li cas los xij, koj tuaj yeem nrhiav lawv daim ntawv thov hauv cov hniav nyiaj hniav kub.
Lwm yam ntawm kev txheeb xyuas
Siv lub suab: txij li tooj liab yog cov hlau muag muag, nws tsim cov suab muted thaum tawm tsam lwm yam. Ib qho kev ntsuas tau nqa tawm thaum xyoo 1987 piav txog Copper lub suab li 'Tuag' Thaum Brass tau hais tias yuav sau cov ntawv ntshiab suab nrov '. Kev txiav txim nrog hom qauv no yog qhov nyuaj uas tsis muaj kev paub. Qhov xwm zoo yog tias kev kawm no txoj kev dhau sijhawm yog pab tau tshwj xeeb tshaj yog rau cov khoom siv qub lossis kev sib sau ua ke. Hom qauv no ua haujlwm zoo tshaj rau cov qauv khoom.
Xaiv txoj cai hlau rau koj qhov project
Kev xaiv ntawm cov hlau txoj cai rau ib daim ntawv thov yog qhov tseem ceeb tshaj plaws kom nco ntsoov thaum nws los tsim cov khoom lag luam zoo lossis cov khoom lag luam zoo lossis qhov chaw zoo. Txawm hais tias ob qho tib si hlau (tooj liab & tooj dag) muab cov thermal thiab hluav taws xob ua haujlwm, thiab ntau dua, lawv txhua tus muaj kev sib txawv.
Thaum txhua tus tooj liab thiab tooj dag yog ruaj, lawv tsis muaj tib theem ntawm kev yoog raws. Nyob rau hauv kev xaiv rau koj qhov project, cov pa roj oxygen dawb nthuav tawm qhov kev hloov pauv loj tshaj plaws, kev ua haujlwm, thiab kev ua haujlwm, thiab ductility thaum bronze.
Hais txog cov nqi hluav taws xob dav dav, tooj dag feem ntau tau txiav txim siab thiab feem ntau haum rau cov ntawv thov dav dav. Nws yog ib qho yooj yim los nrum, kuj pheej yig, thiab malleable nrog kev sib txhuam qis. Tooj dag yog qhov muaj peev xwm tshaj plaws rau cov khoom dai kom zoo nkauj thiab rau cov hlau uas cov neeg tuaj ntsib nrog lub dorknob. Nws yog siv nyob rau hauv cov khoom lag luam ua lag luam rau cov qib khoom uas xav tau kev tiv thaiv los ntawm cov microbial thiab cov kab mob sib kis.
Ntsiab lus: tooj dag vs. Tooj liab, uas ib qho zoo tshaj plaws rau koj qhov project?
Nkag siab txog cov khoom ntawm tooj dag thiab tooj liab yog qhov tseem ceeb los xaiv cov khoom siv zoo tshaj plaws rau koj cov haujlwm. Nws pab muab cov lus teb rau cov hnub nyoog muaj hnub nyoog ntawm "uas yog qhov zoo dua ntawm tooj liab thiab tooj dag." Peb cov ntaub ntawv ntxaws ntxaws yuav ua rau koj paub tias ob qho tib si ntawm cov hlau muaj txiaj ntsig zoo dua hauv lawv daim ntawv thov. Hauv kev xaus, ob qho tib yam me me yog qhov zoo dua rau lawv cov ntawv thov tshwj xeeb.
Yog tias koj xav tau Machining tooj los yog tshuab luam ntawv tooj liab, Jindalai yog qhov zoo tshaj plaws uas koj tuaj yeem ntseeg tau, Kuv zoo siab tau hnov los ntawm koj!
