Txawm hais tias GB/T 470-2008 thiab GB/T 13818-2024 ob leeg zoo li muaj feem cuam tshuam nrog zinc, lawv cov xwm txheej siv tiag tiag thiab cov hom khoom sib txawv kiag li. Qhov sib txawv tseem ceeb feem ntau yog nyob rau hauv qhov ntau thiab tsawg ntawm daim ntawv thov, cov khoom nws tus kheej, thiab cov kev cai tshwj xeeb. Lawv tuaj yeem sib txawv hauv cov hauv qab no:
1. Scope ntawm Daim Ntawv Thov & Lub Hauv Paus Tseem Ceeb
Lub npe tag nrho ntawmGB/T 470-2008 is "Cov Zinc Ingots."Raws li lub npe qhia, tus qauv no hais txog cov khoom zinc ingot. Nws siv rau cov zinc ingots tsim los ntawm kev siv cov zinc concentrate lossis cov khoom siv zinc ua cov khoom siv raw, tsis hais seb cov txheej txheem tsim khoom puas cuam tshuam nrog kev distillation, rectification, lossis electrolysis. Cov zinc ingots no feem ntau yog cov khoom siv raw rau kev lag luam xws li galvanizing, alloy manufacturing, tshuaj lom neeg, thiab kev tsim hluav taws xob, ua lub hauv paus raw khoom rau zinc hauv kev tsim khoom lag luam.
Nyob rau hauv sib piv, lub npe tag nrho ntawmGB/T 13818-2024 is "Cov hlau zinc uas raug nias kom tuag,"uas tsom mus rau cov zinc alloys tsim rau die-casting. Nws yog siv rau kev tsim khoom thiab kev tshuaj xyuas ntawm die-cast zinc alloys. Tsis zoo li zinc ingots, cov khoom no yog siv ncaj qha rau hauv cov txheej txheem die-casting rau cov khoom siv tsheb, cov khoom siv hluav taws xob, thiab lwm yam khoom, hloov kho rau ntau yam xwm txheej die-casting tsis tas yuav tsum tau ua cov khoom siv raw ntxiv.
2. Hom Khoom & Cov Kev Cai Rau Kev Sib Xyaws
GB/T 470-2008 — Cov Khoom Zinc Ntshiab
Qhia txog cov khoom zinc ntshiab uas muab faib ua tsib qib raws li cov tshuaj lom neeg sib xyaw:Zn99.995, Zn99.99, Zn99.95, Zn99.5, thiab Zn98.5.Tus qauv no piav qhia meej txog cov ntsiab lus zinc thiab qhov siab tshaj plaws uas tso cai rau cov khoom tsis huv xws li txhuas, cadmium, thiab hlau. Rau qib Zn99.995, cov ntsiab lus zinc yuav tsum tsis pub tsawg dua 99.995%, thiab tag nrho cov khoom tsis huv yuav tsum tsis pub tshaj 0.005%. Tus qauv no kuj tshem tawm cov kev cai rau arsenic thiab antimony thiab kho cov kev txwv ntawm cov ntsiab lus txhuas rau qee qib.
GB/T 13818-2024 — Cov Khoom Siv Zinc Uas Ua Los Ntawm Tuag
Qhia txog cov zinc alloys uas muaj cov khoom sib xyaw xws li txhuas thiab tooj liab los txhim kho kev ua haujlwm casting. Piv rau cov version dhau los, nws qhia txog ob qib tshiab -YZZnAl4CthiabYZZnAl3Cu5— coj tag nrho cov qib mus rau cuaj. Tus qauv tswj cov khoom sib xyaw ua ke zoo (txhuas, tooj liab, magnesium) thiab txwv tsis pub muaj cov khoom tsis huv xws li txhuas, cadmium, thiab hlau. Nws kuj ntxiv cov kev cai zoo ntawm qhov chaw, txwv tsis pub muaj qhov tsis zoo xws li npuas, roj av, thiab cov khoom suav nrog, thaum cov qhov me me thiab cov cim tiav raug tso cai.
3. Cov Qauv Txuj Ci & Cov Lus Qhia Txog Kev Siv
GB/T 470-2008tau kho dua tshiab los txais yuav ISO 752: 2004, feem ntau yog cov qauv rau cov zinc ingots, cov txheej txheem sim, cov cai tshuaj xyuas, nrog rau kev cim, ntim khoom, kev thauj mus los, thiab kev khaws cia. Cov txheej txheem sim feem ntau yog raws li GB / T 12689 series ntawm cov qauv; cov txheej txheem kuaj tsis txais yuav cov qauv thoob ntiaj teb ISO; kev cim xim ua raws li cov qauv hauv tsev thawj; thiab qhov hnyav ntawm cov zinc ingots yog teev tseg ntawm18 kg thiab 30 kg.
GB/T 13818-2024hloov qhov version dhau los, GB/T 13818-2009, thiab tau sau raws li cov cai ntawm GB/T 1.1—2020. Piv rau qhov version dhau los, nws ntxiv ib tshooj ntawm cov cai tshuaj xyuas, kho dua cov txheej txheem xeem rau cov tshuaj lom neeg, thiab hloov kho cov kev cai rau kev cim, ntim khoom, kev thauj mus los, thiab kev khaws cia. Cov txheej txheem xeem tau ua raws li cov kev xav tau niaj hnub no, suav nrogcov txheej txheem spectroscopicthiabkev siv inductively coupled plasma-emission spectroscopy (ICP-ES).Tsis tas li ntawd xwb, tus qauv muab cov lus sib piv ntawm cov qib qauv hauv tebchaws Suav thiab cov qauv txawv teb chaws los pab txhawb kev xa khoom tawm.
4. Cov Xwm Txheej Thov
Cov zinc ingots uas tau npog los ntawmGB/T 470-2008ua cov khoom siv raw khoom tseem ceeb hauv kev tsim khoom lag luam, feem ntau yog siv rau kev ua tiav tom qab - xws li galvanizing, zinc alloy tsim, thiab ua cov khoom siv tshuaj lom neeg - thiab ua lub hauv paus rau kev siv zinc hauv kev lag luam.
Cov zinc alloys uas tau die-casted yog coated nrogGB/T 13818-2024yog cov khoom siv molding siv ncaj qha rau hauv kev tsim khoom die-casting. Lawv sib xws nrog ntau yam txheej txheem, xws li chav kub thiab chav txias die-casting, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua rau cov khoom siv high-precision, complex-puab. Cov alloys no siv dav hauvkev lag luam tsheb, khoom siv hluav taws xob, thiab kho vajtse.
Kev Txheeb Xyuas
Hauv cov lus yooj yim, qhov sib txawv tseem ceeb ntawm ob qho yog tiasGB/T 470-2008kav"cov khoom siv zinc ntshiab (zinc ingots),"thaumGB/T 13818-2024kav"zinc alloys tshwj xeeb rau kev tuag casting."Cov qauv khoom, daim ntawv thov, thiab cov kev cai lij choj sib txawv heev, ua rau lawv haum rau ntau yam kev tsim khoom thiab daim ntawv thov.
