Thaum muab khoomzinc hlau rau thermal spray, qib purity koj xaiv ncaj qha cuam tshuam rau cov txheej txheem kev ua tau zoo, daim ntawv cog lus lub zog, thiab kev ua raws li qhov project. Tab sis ntau tus neeg yuav khoom tsis meej pem cov ntawv purity -99.9% vs 99.99% vs 99.995%-thiab saib qhov tseem ceeb ntawmMill Test Certificate (MTC)uas txheeb xyuas nws.
Phau ntawv qhia no suav nrog:
- Yuav ua li cas purity qib piv rau arc tsuag thiab nplaim tsuag daim ntaub ntawv
- Yuav ua li cas daim ntawv pov thawj MTC yuav tsum suav nrog (nrog rau cov lus piv txwv tiag)
- Vim li cas cov kab keeb tsom xam tseem ceeb rau txheej txheej zoo
- Yuav ua li cas txheeb xyuas koj cov zinc hlau raws li EN 1179 / ASTM B6 cov qauv
Dab tsi yog Zinc Hlau Purity thiab Vim Li Cas Nws Tseem Ceeb?
Zinc hlau purity hais txog qhov feem pua ntawm cov zinc hauv cov hlau, nrog rau cov seem uas muaj cov kab tsis huv xws li hlau (Fe), lead (Pb), cadmium (Cd), tooj liab (Cu), thiab tin (Sn).
Hauvthermal txau, cov impurities cuam tshuam rau:
- Txheej adhesion- impurities tsim cov chaw tsis muaj zog ntawm daim ntawv cog lus interface
- Porosity- purity siab dua ua rau denser, tsawg dua cov txheej txheej
- Corrosion kuj- galvanic hlwb tsim nyob ib ncig ntawm qhov chaw impurity
- Txau qhov sib xws- molten droplet cwj pwm hloov nrog muaj pes tsawg leeg
Raumuaj zinc hlau rau thermal tsuag, 99.995% purity (qib 4N5) yog tus qauv tsim rau kev xav tau ib puag ncig.

Dab tsi yog MTC Daim Ntawv Pov Thawj rau Zinc Hlau?
IbMTC (Mill Test Certificate), kuj hu adaim ntawv pov thawj zeblos yogDaim ntawv pov thawj ntawm kev txheeb xyuas (COA), yog cov ntaub ntawv zoo tshaj tawm los ntawm cov chaw tsim khoom zinc hlau. Nws muab pov thawj traceable tias ib qho kev tsim khoom tshwj xeeb ua tau raws li cov txheej txheem tshuaj lom neeg thiab cov cuab yeej cuab tam.
Rau kev siv tshuaj tsuag thermal, MTC siv tau feem ntau yuav tsum tau ua rau:
- Kev ua raws li ISO 2063 / EN 14616
- OEM project specifications
- Kev pom zoo kev tiv thaiv thiab marine classification Society
- Kev soj ntsuam xyuas zoo thiab traceability

Qhov kev nthuav dav no ua rau tus neeg siv kawg kom paub tseeb tias cov xaim ua raws li qhov project specifications ua ntej daim ntawv thov. Cov tuam txhab muaj koob npe muab MTCs nrog txhua pawg raws li kev thov.
Yuav Ua Li Cas Nyeem Daim Ntawv Pov Thawj Zinc Hlau Mill
Kev nyeem ntawv MTC kom raug pab koj kom tsis txhob raug nqi ntau yam yuam kev. Nov yog dab tsi los nrhiav:
- Tshawb xyuas cov lus tshaj tawm purity- txheeb xyuas Ntau dua lossis sib npaug rau 99.995% Zn lossis koj qib teev tseg
- Ua kom sov tus lej- batch naj npawb ntawm daim ntawv pov thawj yuav tsum phim cov spool labels
- Tshawb xyuas cov kab ke- txhua kab impurity yuav tsum qis dua qhov siab tshaj plaws tso cai rau koj qib
- Txheeb xyuas tus qauv- EN 1179 rau cov haujlwm European, ASTM B6 rau North American cov haujlwm
- Tshawb xyuas hnub- daim ntawv pov thawj yuav tsum tam sim no nyob rau hauv 12 lub hlis ntawm kev tsim khoom
Yog vim li cas Trace Element Levels Matter for Coating Quality
Txawm nyob rau ntawm qhov chaw -ib - lab ppm qib, qee yam impurities tuaj yeem ua rau cov thermal spray txheej ua tau zoo:
- Hlau (Fe)- cov ntaub ntawv nkig intermetallic theem thiab txo cov txheej ductility
- Lead (Pb)- tsim qis- melting- cov ntsiab lus suav nrog uas ua rau cov txheej tsis muaj zog ntawm qhov kub siab
- Cadmium (Cd)- ua rau muaj kev txhawj xeeb txog ib puag ncig thiab toxicity nyob rau hauv cov chaw tso tshuaj tsuag
- Copper (Cu)- hloov galvanic peev xwm thiab tuaj yeem txo cov kev tiv thaiv cathodic
- Tin (Sn)- cuam tshuam qhov nro ntawm cov kwj deg molten thiab tej zaum yuav ua rau muaj qhov tsis sib xws
Qhov no yog vim li cas qhiazinc hlau trace element tsom xam ntawm MTCtsis yog formality. Nws ncaj qha cuam tshuam rau txheej zoo thiab qhov project lifespan.
Nqi vs Kev Ua Lag Luam Ua Lag Luam - tawm los ntawm Purity Qib
Xaiv qhov zoo purity qib sib npaug cov kev xav tau ntawm kev siv nyiaj txiag:
- 99.9% (3N)- tsim nyog rau cov ntawv thov tsis zoo nyob hauv tsev, kev tiv thaiv corrosion ib ntus, lossis qhov twg cov khoom siv zog qis dua 15 MPa tau txais. Tsis pom zoo rau kev ua haujlwm raws li ISO 2063.
- 99.99% (4N)- txaus rau feem ntau architectural thiab structural steel tej yaam num. Zoo sib npaug ntawm cov nqi thiab kev ua haujlwm zoo.
- 99.995% (4N5)- qib uas nyiam tshaj rau offshore, marine, choj thiab OEM daim ntawv thov. Yuav tsum tau rau tej yaam num qhia EN 1179 los yog ASTM B6 nrog nruj impurity txwv.
Tus nqi hwm rau 99.995% tshaj 99.99% feem ntau yog 10-15%, thaum txheej txheej kev txhim kho tuaj yeem yog 30-50% nyob rau hauv ib puag ncig corrosive. Qhov no ua rau cov qib siab dua tus nqi ntau dua - ua tau zoo tshaj qhov kev ua haujlwm tag nrho.
