1.Dab tsi yog qhov zoo ntawm plasma txiav galvanized coils?
Kev kub ceev: Plasma txiav yog ceev heev, ua rau nws haum rau siab - efficiency ntau lawm.
Adaptable: Txawm tias tuab npaum li cas ntawm zinc txheej, nws tuaj yeem txiav tau zoo vim tias qhov kub ntawm cov plasma arc nyob deb tshaj qhov melting point ntawm zinc thiab hlau.
Tsis Siv Neeg Pretreatment: Tsis muaj zinc txheej yuav tsum tau muab tshem tawm ua ntej txiav.
2.Dab tsi yog qhov tsis zoo ntawm plasma txiav galvanized kauj?
Kev tsim cov tshuaj lom zinc fumes: Qhov no yog qhov kev txhawj xeeb loj tshaj plaws thiab kev pheej hmoo.
Nto zoo: Qhov kev txiav yuav tsis zoo li laser txiav, thiab zinc evaporation tuaj yeem muaj kev cuam tshuam loj.
Post- tiv thaiv corrosion: zinc txheej ntawm ntug txiav yog puas, yuav tsum tau tom qab- kho.
3.Dab tsi yog qhov txaus ntshai ntawm cov pa phem (zinc fumes) thiab kev tiv thaiv kev nyab xeeb?
Zinc muaj qhov kub kub ntawm kwv yees li 907 degree, thaum lub plasma arc kub nce mus txog kaum tawm txhiab degrees, ua rau nws tam sim ntawd vaporize thiab oxidize, tsim zinc oxide fumes. Kev nqus pa ntawm cov pa no tuaj yeem ua rau "hmoov hlau fume," nrog cov tsos mob zoo ib yam li mob khaub thuas hnyav, xws li ua npaws, ua daus no, xeev siab, mob taub hau, thiab qaug zog. Ntev - raug rau lub sij hawm ua rau muaj kev phom sij heev rau kev noj qab haus huv.
4.Dab tsi yog cov kev daws teeb meem rau cov pa luam yeeb (zinc pa luam yeeb) thiab kev tiv thaiv kev nyab xeeb?
Forced exhaust system: Qhov no yog qhov tseem ceeb heev. Lub rooj txiav yuav tsum tau nruab nrog kev txiav hauv qab dej los yog lub tshuab tso tawm muaj zog nrog lub siab -cov khoom siv plua plav (xws li lub lim cartridge) txhawm rau ntes cov pa taws ntawm qhov chaw.
Cov cuab yeej tiv thaiv tus kheej:
Kev Tiv Thaiv Kev Ua Phem: Hnav ib lub tshuab ua pa uas pom zoo los yog muab rau -air respirator.
Kev Tiv Thaiv Qhov Muag: Hnav tsom iav kev nyab xeeb lossis daim npog ntsej muag.
Kev Tiv Thaiv Lub Cev: Hnav cov nplaim taws- cov khaub ncaws ua haujlwm thiab hnab looj tes tiv thaiv.
Kev Ua Haujlwm Zoo: Ua kom muaj qhov cua zoo thoob plaws hauv lub rooj cob qhia kom tsis txhob muaj fume tsub zuj zuj.
5.Dab tsi yog cov kev daws teeb meem rau kev txiav zoo thiab kev tiv thaiv ntug?
Ntug zinc ablation: Kub kub nyob ze ntawm qhov txiav ua rau cov zinc txheej evaporate thiab oxidize, tsim ib qho chaw tsis muaj kev tiv thaiv. Qhov chaw no feem ntau yog nqaim, tab sis dav txaus kom nthuav tawm lub hauv paus steel matrix.
Dross: Oxidized thiab melted hlau residues yuav ua raws li hauv qab ntawm kev txiav, ua kom huv si nyuaj dua li cov hlau zoo tib yam.
Txiav zoo: Tej zaum yuav tsis zoo li laser txiav, tshwj xeeb tshaj yog thaum siv cov pa plasma (tsis siab -plasma precision).
Kev daws:
Optimize txiav parameter:
Gas xaiv: Siv nitrogen los yog hydrogen-nitrogen sib tov raws li cov roj plasma ua kom huv si txiav thiab txo oxidation.
Tam sim no thiab ceev: Siv lub txiav ceev dua thiab tsim nyog tam sim no. Kev txiav nrawm nrawm dua txo cov cua sov nkag, txo cov cua sov- thaj tsam cuam tshuam ntawm zinc txheej thiab cov khoom siv.
