Qee lub sij hawm hu ua 'liab hlau', tooj liab, tooj dag thiab tooj dag tuaj yeem nyuaj los qhia sib nrug. Zoo sib xws hauv cov xim thiab feem ntau ua lag luam hauv tib pawg, qhov sib txawv ntawm cov hlau no yuav ua rau koj xav tsis thoob! Thov saib peb daim ntawv sib piv hauv qab no kom muab lub tswv yim rau koj:
| Xim | Tej kev siv | Cov txiaj ntsig | |
| Tooj | Txiv kab ntxwv-tinted liab | ● Cov yeeb nkab & yeeb nkab fittings ● Hluav taws xob | ● High hluav taws xob & thermal conductivity ● Yooj yim soldered thiab ductile heev ● Txaus siab rau cov kab mob tua kab mob |
| tooj dag | Muaj peev xwm ntau ntawm liab mus rau kub xim nyob ntawm seb qib zinc ntxiv rau cov hlau | ● Cov khoom zoo nkauj ● Suab paj nruag | ● Txaus nyiam, xim zoo li kub ● Kev ua haujlwm zoo & ua haujlwm ntev ● Lub zog zoo heev, nrog ntau dua 39% zinc |
| Bronze | Daj kub | ● Khoom plig & khoom plig ● Cov duab puab ● Muaj bushings & bearings | ● Corrosion resistant ● Cov cua kub thiab hluav taws xob ntau dua li cov hlau feem ntau. |
1. Copper yog dab tsi?
Copper yog ib qho khoom siv hlau uas muaj nyob rau ntawm lub rooj zaum. Nws yog ib qho khoom siv ntuj tsim uas tuaj yeem pom nyob hauv lub ntiaj teb thiab yog cov khoom muaj nyob hauv tooj dag thiab tooj dag. Copper mines extract raw tooj liab los ntawm lub ntiaj teb nto thiab tuaj yeem pom thoob plaws ntiaj teb. Vim tias cov hlau no yog cov khoom siv hluav taws xob zoo thiab muaj peev xwm tiv taus cua sov, nws feem ntau siv hauv cov tshuab hluav taws xob thiab khoos phis tawj. Cov kav dej tooj liab kuj nquag siv hauv cov kav dej. Qee yam khoom siv feem ntau ua los ntawm tooj liab uas tau siv dua ntawm cov khoom seem xws li tooj liab hlau, cable, thiab tubing. Tooj liab yog ib qho ntawm cov hlau muaj nqis tshaj plaws ntawm cov khoom seem.
2. Brass yog dab tsi?
Brass yog cov hlau alloy, uas txhais tau hais tias nws yog cov hlau ua los ntawm ntau yam khoom. Nws yog kev sib xyaw ntawm tooj liab thiab zinc, thiab qee zaum tin. Qhov sib txawv ntawm cov feem pua ntawm tooj liab thiab zinc tuaj yeem tsim qhov sib txawv ntawm cov xim thiab cov khoom ntawm tooj dag. Nws qhov tsos txawv ntawm daj mus rau ib tug dull kub. Ntau zinc ua rau cov hlau muaj zog thiab ua kom muaj zog dua, thiab nws ua rau cov xim daj ntau dua. Vim nws cov durability thiab workability, tooj dag yog feem ntau siv nyob rau hauv cov kav dej fixtures, mechanical Cheebtsam, thiab suab paj nruas instruments. Nws kuj yog siv rau kev kho kom zoo nkauj vim nws cov tsos kub.
3. Bronze yog dab tsi?
Zoo li tooj dag, bronze yog cov hlau alloy uas ua los ntawm tooj liab thiab lwm yam khoom. Ntxiv nrog rau tooj liab, tin yog cov khoom siv ntau tshaj plaws nyob rau hauv bronze, tab sis bronze kuj tseem muaj zinc, arsenic, aluminium, silicon, phosphorus, thiab manganese. Txhua qhov sib xyaw ua ke tsim cov khoom sib txawv hauv cov txiaj ntsig alloy. Qhov sib ntxiv ntawm lwm cov ntsiab lus ua rau bronze nyuaj dua li tooj liab ib leeg. Vim nws qhov tsos kub thiab lub zog, bronze yog siv rau hauv cov duab puab, suab paj nruag, thiab khoom plig. Nws kuj yog siv rau hauv kev lag luam kev siv xws li bearings thiab bushings vim nws tsis tshua muaj hlau-ntawm-hlau txhuam. Bronze muaj kev siv cov nautical ntxiv vim nws tsis kam tiv thaiv corrosion. Nws kuj yog ib tug zoo conductor ntawm tshav kub thiab hluav taws xob.
4. Qhov sib txawv ntawm tooj liab, tooj dag, thiab tooj liab
Brass thiab bronze yog ob qho tib si ib feem ntawm tooj liab, uas yog vim li cas qee zaum nws yuav nyuaj rau qhia qhov txawv ntawm cov hlau thiab nws cov alloys. Txawm li cas los xij, txhua tus muaj cov yam ntxwv thiab cov yam ntxwv uas ua rau nws txawv thiab txawv ntawm lwm tus. Nov yog qee txoj hauv kev qhia tooj liab, tooj dag, thiab tooj liab sib nrug ntawm ib leeg.
● Xim
Tooj liab muaj qhov txawv xim liab-xim av. Brass muaj qhov ci daj-kub zoo li. Bronze, lub sijhawm no, yog cov xim kub lossis xim sepia thiab feem ntau yuav muaj cov nplhaib tsis zoo ntawm nws qhov chaw.
● Suab
Koj tuaj yeem maj mam ntaus cov hlau los kuaj seb nws puas yog tooj liab lossis alloy. Tooj liab yuav tsim lub suab sib sib zog nqus. Cov tooj liab thiab tooj liab yuav ua rau lub suab nrov dua, nrog tooj dag suab zoo dua.
● Kev sib xyaw
Tooj liab yog ib yam khoom nyob rau hauv lub sij hawm lub sij hawm, uas txhais tau hais tias tsuas muaj nyob rau hauv ntshiab tooj liab yog tooj liab. Txawm li cas los xij, qee zaum nws yuav muaj impurities lossis lwm yam khoom sib xyaw ua ke. Brass yog ib qho alloy ntawm cov ntsiab lus tooj liab thiab zinc thiab tuaj yeem muaj tin thiab lwm yam hlau zoo li. Bronze yog ib qho alloy ntawm cov ntsiab lus tooj liab thiab tin, tab sis qee zaum silicon, manganese, aluminium, arsenic, phosphorus, lossis lwm yam ntxiv. Bronze thiab Brass tuaj yeem muaj ntau yam tib yam hlau, tab sis niaj hnub bronze feem ntau muaj feem pua ntawm tooj liab ntau dua - txog 88% ntawm qhov nruab nrab.
● Magnetism
tooj liab, tooj dag, thiab tooj dag yog tag nrho cov txheej txheem uas tsis yog-ferrous thiab yuav tsum tsis txhob sib nqus. Txawm li cas los xij, txij li tooj liab thiab tooj liab yog cov hlau nplaum, qee zaum cov kab hlau tuaj yeem ua rau lawv txoj hauv kev thiab tuaj yeem kuaj pom los ntawm cov hlau nplaum muaj zog. Yog tias koj tuav cov hlau nplaum muaj zog rau cov hlau hauv nqe lus nug thiab nws teb, ces koj tuaj yeem txiav txim siab tias nws yog tooj liab.
● Durability
Bronze yog ib qho nyuaj, ruaj khov, thiab tsis yooj yim flexed. Brass yog qhov tsawg tshaj plaws, nrog tooj liab hauv nruab nrab. Brass tuaj yeem tawg yooj yim dua li ob qho tib si. Copper, lub sijhawm no, yog qhov hloov tau yooj yim tshaj plaws ntawm peb. Brass kuj tseem tiv taus corrosion ntau dua tooj liab, tab sis tsis resistant li bronze. Tooj liab yuav oxidize lub sij hawm thiab tsim ib tug ntsuab patina los tiv thaiv nws los ntawm ntxiv corrosion.
