Txaus siab rau tsab xov xwm, qhov sib txawv thiab daim ntawv thov ntawm tooj dag kab thiab tooj liab kab, piav qhia cov ntaub ntawv, kev siv thiab cov yam ntxwv ntawm tooj dag thiab tooj liab raws.
1. Cov kab tooj dag yog dab tsi?
(1) Lub ntsiab lus
Brass kab muaj lub zog siab, zoo plasticity, haum rau kev ua haujlwm txias thiab kub, zoo weldability thiab corrosion kuj. Nws yog siv rau condensation thiab tshav kub dissipation raj, serpentine raj, siphons, txias khoom qhov chaw, thiab muaj zoo mechanical zog. Zoo plasticity, zoo machinability, weldability, zoo corrosion kuj, ntau yam sib sib zog nqus extension thiab dabtsi yog khoov quab yuam-bearing qhov chaw, xws li pins, ceev, barometer springs, tshav kub dissipation, nplhaib qhov chaw. Lead tooj dag phaj yog ib qho siv lead ua tooj dag. Nws muaj zoo mechanical zog thiab zoo machinability. Nws tuaj yeem tiv taus kub thiab txias ua haujlwm. Nws yog siv nyob rau hauv ntau yam structural qhov chaw rau txiav thiab stamping ua, xws li gaskets, Bushings thiab lwm yam. Tin tooj dag phaj muaj siab corrosion kuj, zoo mechanical zog, thiab zoo siab processability nyob rau hauv txias thiab kub tej yam kev mob. Nws tuaj yeem siv rau qhov chaw tiv thaiv corrosion ntawm cov nkoj thiab qhov chaw thiab cov kav dej hauv kev sib cuag nrog chav, roj thiab lwm yam xov xwm. Cov kab tooj liab muaj cov khoom siv zoo, hluav taws xob conductivity, thermal conductivity tsawg, zoo corrosion kuj, thiab nyiam corrode thiab tawg. Lawv yog ib qho tseem ceeb corrosion-resistant qhov chaw thiab qhov chaw rau cov hluav taws xob tsis muaj zog tam sim no industries.
H90 high-precision tooj dag kab cov yam ntxwv thiab cov peev txheej ntawm daim ntawv thov: siab zog dua tooj liab (tab sis ntawm cov tooj dag zoo tib yam, nws yog qhov qis tshaj), hluav taws xob zoo thiab thermal conductivity, thiab siab corrosion kuj nyob rau hauv cov huab cua thiab dej tshiab, thiab muaj plasticity zoo, yooj yim txias thiab kub siab ua, yooj yim vuam, forging thiab tin plating, thiab tsis muaj kev nyuaj siab corrosion cracking. Thermal ua kub yog 850 ~ 950 degree; annealing kub yog 650 ~ 720 degree; low-temperature annealing kub kom tshem tawm cov kev ntxhov siab sab hauv yog 200 degree.
(2) Kev sib xyaw
Brass phaj yog ib qho alloy uas muaj tooj liab thiab zinc. Yog tias tooj dag tsuas yog tsim los ntawm tooj liab thiab zinc, nws yog hu ua tooj dag zoo tib yam. Brass feem ntau yog siv los ua cov li qub, cov kav dej, txuas cov kav dej rau cov cua txias sab hauv thiab sab nraud thiab cov radiators. "Yog tias nws yog ntau hom alloys uas muaj ntau tshaj li ob lub ntsiab lus, nws yog hu ua tooj dag tshwj xeeb. Piv txwv li, tooj liab alloy muaj cov hlau lead, tin, manganese, npib tsib xee, hlau, thiab silicon, tooj dag muaj zog hnav tsis kam. Brass kuj hu ua tooj dag tshwj xeeb Nws muaj lub zog siab, siab hardness, thiab muaj zog tiv taus cov tshuaj corrosion kuj muaj cov khoom siv zoo heev hauv kev txiav cov yeeb nkab tooj liab ua los ntawm tooj dag yog mos thiab hnav-tiv taus tuaj yeem siv rau cov khoom siv hluav taws xob thiab cov condensers, cov kav dej cryogenic, cov kav dej hauv nkoj thauj mus los, thiab lwm yam, nrog cov ntsiab lus tooj liab ntawm 62% mus rau 68%. tooj dag, tooj dag muab faib ua ob hom: tooj dag zoo tib yam thiab tooj dag tshwj xeeb siv rau kev ua haujlwm siab yog hu ua deformed tooj dag.
(3) Lub Hom Phiaj
Nws tuaj yeem siv los ua ntau yam sib sib zog nqus thiab khoov qhov kev ntxhov siab, xws li pins, rivets, washers, txiv ntseej, conduits, cua siab ntsuas, cov ntxaij vab tshaus, radiator qhov chaw, thiab lwm yam. Nws muaj cov khoom siv zoo, zoo plasticity hauv kub. lub xeev, siv tau plasticity nyob rau hauv txias xeev, zoo machinability, yooj yim vuam thiab vuam, thiab corrosion kuj. Nws yog ib hom tooj dag ntau siv dav.

(5) Cov yam ntxwv ntawm tooj dag
1. Nws muaj qhov zoo ntawm kev ua kom huv ntawm sab hauv thiab sab nraud, ultra-brightness, uniform thiab ntom qauv, siab qhov tseeb, thiab zoo formability;
2. Cov kab tooj dag muaj lub zog siab, zoo plasticity, haum rau kev ua haujlwm txias thiab kub, muaj qhov zoo weldability thiab corrosion kuj, muaj cov khoom siv zoo, muaj plasticity zoo hauv lub xeev kub, zoo machinability, zoo weldability thiab corrosion kuj;
2. Dab tsi yog kab tooj liab?
(1) Lub ntsiab lus
Cov kab tooj liab kuj hu ua liab tooj liab, uas yog tooj liab ntshiab. Nws muaj npe tom qab nws cov xim yog xim liab. Ntau yam khoom muaj nyob hauv tooj liab. Cov tooj liab liab yog cov tooj liab ntshiab, nrog lub melting point ntawm 1083 degree, tsis muaj allotropic transformation, thiab ib tug txheeb ze ntom ntawm 8.9. Qhov loj ntawm tib lub ntim yog li 15% hnyav dua li cov hlau zoo tib yam. Vim tias nws muaj xim liab liab thiab hloov ntshav tom qab ib zaj duab xis oxide tsim rau saum npoo, nws feem ntau hu ua liab tooj liab. Nws yog tooj liab uas muaj qee yam ntawm cov pa oxygen, yog li nws tseem hu ua oxygen-muaj tooj liab.
Nws tsis tas yog tooj liab dawb huv. Qee lub sij hawm me me ntawm deoxidizing cov ntsiab lus lossis lwm cov ntsiab lus tau ntxiv los txhim kho cov khoom siv thiab kev ua haujlwm, yog li nws kuj tau muab faib ua tooj liab alloy. Tuam Tshoj cov khoom siv tooj liab kab tuaj yeem muab faib ua: kab tooj liab zoo tib yam (T1, T2, T3, T4), tooj liab tsis muaj oxygen (TU1, TU2 thiab siab-purity, nqus pa tsis muaj tooj liab), deoxidized tooj liab (TUP, TUMn) , ntxiv Plaub hom tshwj xeeb tooj liab nrog ib qho me me ntawm alloying ntsiab (arsenic tooj liab, tellurium tooj liab, nyiaj tooj liab). Cov hluav taws xob conductivity thiab thermal conductivity ntawm tooj liab liab yog qhov thib ob tsuas yog nyiaj, thiab nws tau siv dav hauv kev ua cov khoom siv hluav taws xob thiab thermal conductive. Liab tooj liab yog tawm hauv cov huab cua, dej hiav txwv thiab tej yam uas tsis yog-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, ntsev tov thiab ntau yam organic acids (acetic acid, citric acid). Nws muaj kev tiv thaiv corrosion zoo thiab siv hauv kev lag luam tshuaj. Tsis tas li ntawd, cov phaj tooj liab muaj qhov zoo weldability thiab tuaj yeem ua rau ntau yam khoom siv ua tiav thiab cov khoom tiav los ntawm kev ua cov yas txias thiab kub. Nyob rau xyoo 1970, cov zis ntawm cov kab tooj liab tau tshaj tag nrho cov txiaj ntsig ntawm lwm hom tooj liab alloys.
(2) Nta
Nws muaj kev tiv thaiv corrosion zoo thiab siv hauv kev lag luam tshuaj.
(3) Qhov sib txawv ntawm cov kab tooj dag
"Brass" nyuaj tshaj "liab tooj"! Liab tooj liab, tseem hu ua liab tooj liab, yog tooj liab ntshiab. Muaj qhov sib txawv ntawm xim thiab zoo ntawm liab tooj liab thiab tooj dag! Qhov tseeb, xim yog pom tseeb ntawm ib nrais muag, raws li lub npe qhia! Nyob rau hauv cov nqe lus ntawm zoo, liab tooj liab yog zoo dua Nws yog ib qho nyuaj tshaj li tooj dag thiab muaj txog tib lub luj. Ntshiab tooj liab kuj hu ua liab tooj liab. Nws qhov ceev yog 7.83g / cm3 thiab nws cov ntsiab lus melting yog 1083 degrees. Nws yog non-magnetic, muaj hluav taws xob zoo thiab thermal conductivity, corrosion kuj thiab toughness. Qhov ntom ntawm tooj dag yog ((8.93g / cm3) feem ntau yog siv los ua cov txheej txheem kev coj tus kheej, thiab hnav-tiv taus " tooj dag" muaj qhov ntom ntom ntau dua li cov tooj liab liab.
Brass kab, tooj liab-raws li alloy nrog zinc raws li cov ntsiab lus alloy, muaj npe tom qab nws cov xim daj feem ntau. Brass muaj qhov zoo nkauj radiance, cov txheej txheem zoo thiab cov khoom siv kho tshuab, hluav taws xob thiab thermal conductivity, corrosion kuj nyob rau hauv cov huab cua, dej tshiab thiab dej hiav txwv, yooj yim txiav thiab polishing, zoo weldability thiab luv nqi. Nws feem ntau yog siv los ua cov khoom siv hluav taws xob thiab cov thermal, cov khoom siv corrosion-resistant, cov khoom siv elastic, cov khoom siv niaj hnub thiab cov khoom siv zoo nkauj, thiab lwm yam. Nws muaj ntau yam kev siv.
Feem ntau hais lus, qhov kev ua tau zoo ntawm cov kab tooj dag yog zoo dua li ntawm cov kab tooj liab (cov kab tooj liab yog ib qho yooj yim los lo rau ntawm rab riam); nyob rau hauv cov nqe lus ntawm tsis-txiav ua, lub deformation kuj ntawm liab tooj liab kab yog me me thiab yooj yim rau daim ntawv. Cov kab tooj liab yog tooj liab ntshiab. Cov xim ntawm cov tooj liab ntshiab yog txiv kab ntxwv lossis liab liab, tab sis nws yuav oxidized rau hauv ntshav thaum raug huab cua, yog li nws hu ua tooj liab kab. Cov kab tooj dag yog Cu-Zn alloy, muaj txog 80% tooj liab. Lub hardness yog ntau dua li tooj liab, tab sis nws cov hluav taws xob thiab thermal conductivity tsis zoo.
