Yuav ua li cas kom paub qhov txawv ntawm bronze dag nyob hauv tsev?

Muaj ib tug xov tooj ntawm txoj kev uas qhia rau peb yuav ua li cas kom paub qhov txawv ntawm bronze dag. Nyob rau hauv lub cuav Kuv xav mus xav txog qhov yooj yim tshaj plaws thiab pheej yig daws teeb meem rau qhov kev siv ntawm no ua hauj lwm. Cia peb nrhiav tau li cas kom paub qhov txawv dag los ntawm bronze nyob rau hauv lub tsev.

Yuav ua li cas yog Bronze?

Ua ntej tshuaj ntsuam yuav ua li cas kom paub qhov txawv ntawm tooj dag, bronze, nrhiav seb yog dab tsi txhua lub alloys. Peb pib nrog cov bronze. Yog li, lub bronze yog ib tug hlau ntawm tin thiab tooj liab, hlau ntawm pob zeb ntais, txhuas, beryllium, thiab txhuas. Nws yog qhov zoo tshaj siv lom zem ntau thiab txiav txim seb qhov xwm ntawm tus neej yav tom ntej tin hlau.

Muaj yog ib tug tshwj xeeb zoo ntawm bronze, nyob rau hauv qhov siv thiab ua uas tin yog hloov nrog npib tsib xee los yog zinc. Xws li ib tug hlau yog hu ua shpiatr. Nyob rau hauv qhov tseeb, cov khoom no yog ib tug pheej yig dua kev xaiv ntawm bronze, uas yog yus tsis yog tus zoo tshaj plaws zoo.

Raws li cov saum toj no raug hauv paus ntsiab lus, bronze thiab tin yog cais rau Tinless. Thaum pib ntawm lub xyoo pua xeem steelmakers ua arsenious bronze. Txawm li cas los, vim hais tias ntawm lub high school toxicity ntawm cov khoom thiab yog tsis muaj dav siv.

Yuav ua li cas yog Toog?

Toog yog yuav luag tib yam alloy li bronze. Tab sis tsis txhob siv lub alloying muaj pes tsawg leeg nyob rau hauv daim ntawv ntawm tin ua ke nrog zinc siv tooj liab. Tej zaum hlau ntxiv hmoov txhuas, hlau, npib tsib xee, manganese, thiab lwm yam hais.

Tau txais dag paub yuav ua li cas lub ancient Loos. Nws yog lawv uas xub kawm mus ua ke lub molten tooj liab nrog zinc ore. Ntshiab zinc nyob rau hauv qhov siv thiab ua dag pib tsuas yog siv los rau hauv lub lig 18th xyoo pua nyob rau hauv teb chaws Aas Kiv. British feem ntau siv rau kev tsim ib tug forged hlau kub, vim hais tias dag, raws li cov noble hlau, muaj ib tug txaus nyiam hnub ci.

Niaj hnub no, cov khoom lug siv los tsim thiaj li hu ua lis-hlau - hlau steel uas yog ua ke nrog tooj dag. Cov tshuaj no tswj zus tau tej cov ib tug hlau uas yog resistant rau corrosion thiab abrasion. Txawm li cas los, lub bimetal cov khoom muaj zoo ductility.

Txiav txim qhov txawv ntawm bronze thiab tooj dag

Yuav ua li cas kom paub qhov txawv ntawm bronze dag? Qhov txawv ntawm cov alloys yog raws li nram no:

1. Toog twb npaj los ntawm combining zinc nrog tooj liab. Nyob rau hauv lem, ua tsaug rau bronze tsim fusion ntawm tooj liab thiab tin.
2. Bronze lub sij hawm ntev yuav ua tau nyob rau hauv kev sib cuag nrog hiav txwv, ntsev dej uas tsis muaj kev rhuav tseg cov qauv ntawm cov khoom. Toog, qhov no yuav tsum tau ntxiv ua nyob rau hauv daim ntawv ntawm cov alloying.
3. Bronze muaj ib tug high kuj mus txhua yam coj thiab yog check cov ntaub ntawv uas. Vim li no, lub alloy yog dav siv los tsim tag nrho cov hom ntawm cov mlom thiab monuments. Toog yog tsis haum rau lub hom phiaj no, txawm hais tias nws yog siv raws li ib tug keeb ntawm artistic cov khoom.
4. Yuav ua li cas kom paub qhov txawv tooj liab los ntawm dag thiab bronze? Tooj muaj ib tug reddish Hawj txawm. Nyob rau tib lub sij hawm lub bronze muaj ib tug maub xim av xim, thiab cov ntxhib qauv. Toog muaj tib lub daj xim thiab ib tug zoo-grained khoom.

Sib txawv los ntawm dag, bronze raws li hnyav

Yuav ua li cas kom paub qhov txawv dag los ntawm bronze, raws li qhov nyhav ntawm cov ntaub ntawv? Nws yog ib nqi sau cia hais tias lub bronze yog heev hnyav hlau. Nyob rau hauv vaj huam sib luag volume ntawm teb bronze yog kom meej meej hnyav dua dag. Yog li ntawd, paub qhov txawv cov khoom los ntawm cais alloys yuav luj lawv nyob rau lub xib teg.

Yuav ua li cas kom paub qhov txawv cov alloys los ntawm cua sov?

Peb yuav tsum sim kom paub qhov txawv ntawm cov ntaub ntawv los ntawm thermal los. Txawm li cas los, cov kev tshwm sim nyob rau hauv cov ntaub ntawv no yuav muaj ntau txhim khu kev qha. Yuav ua li cas yuav tsum ua li cas? Ob hlau yuav tsum tau rhuab los ntawm cov pa roj burners mus rau ib tug kub saum toj no 600 ° ^C. Nrog qhov kev txiav txim rau ntawm qhov chaw ntawm tooj dag cov khoom tsim cov quav hniav ashy Hawj txawm uas yog zinc oxide. Nyob rau tib lub sij hawm, lub bronze tseem nyob rau hauv nws thawj daim ntawv.

Tom qab cua sov rau cov tooj dag yuav ua ntau pliable. Bronze tsis hloov nws lub zog nyob rau hauv kub. Yog hais tias koj sim khoov ib tug tooj dag dawb paug, lub tom kawg tsis puas cov qauv. Raws li rau lub bronze, nws yog kom mus ua txhaum down rau ntawm qhov chaw inflection.

Yuav ua li cas kom paub qhov txawv dag los ntawm bronze magnet?

Raws li sau tseg saum toj no, raws li ib feem ntawm bronze yog tam sim no tin thiab cov hlau lead. Cov ntaub ntawv tej zaum yuav attracted rau ib tus hlau nplaum. Qhov tshaj plaws xwb uas yog yuav tsum tau rau cov xyaum ua tej yam - mus nrhiav ib tug heev muaj zog hlau nplaum. Thaum uas siv cov nws, bronze yuav me ntsis Podlipaev mus rau qhov chaw. Nyob rau dag magnet yuav muaj tsis ntxim.

Nyob rau hauv xaus

Raws li koj tau pom, muaj ib tug xov tooj ntawm txoj kev uas tso cai rau koj kom paub qhov txawv ntawm bronze dag nyob rau hauv tsev. Nyob rau hauv feem ntau ntawm cov khoom ntawm cov alloys muaj ib tug qhia tau nrig txog kev pom sib txawv. Yog li ntawd, mus rau tiv nrog neeg ua hauj lwm, tej zaum nws yog txaus cia li mus xav txog ua tib zoo ob cov ntaub ntawv.
