Dab tsi yog galvanized steel
Galvanized steel phaj muab faib ua cov phaj electrolytic zoo tib yam thiab cov ntiv tes tiv thaiv electrolytic phaj. Cov ntiv tes tiv thaiv phaj yog ntxiv rau cov phaj electrolytic zoo tib yam los ntawm kev kho tus ntiv tes tiv thaiv, tuaj yeem tiv hws, feem ntau siv rau hauv qhov chaw yam tsis muaj kev kho mob, lub hom phiaj yog SECC-N. Ordinary electrolytic phaj thiab phosphating phaj thiab passivation phaj, phosphating feem ntau yog siv, lub hom yog SECC-P, feem ntau hu ua p khoom. Passivated daim hlau yuav oiled los yog unoiled.
Piv txwv:
Kub dip zinc steel phaj (SGCC) muaj ib qho zoo dua li hluav taws xob galvanized steel phaj (SECC), SECC dabtsi yog khoov thiab seem yog yooj yim heev rau xeb, SGCC xeb kuj nyob rau hauv tib yam kev mob yog zoo dua. Cov chassis zoo feem ntau siv SECC lossis SGCC galvanized steel phaj, siv cov khoom siv no chassis steel phaj xim ci, xim hlau nplaum, qhov zoo ntawm cov phaj steel no zoo corrosion kuj.
Hluav taws xob galvanized steel phaj (SECC): niaj hnub grey, feem ntau tuaj txawv teb chaws, ntiv tes tsis kam, muaj kev tiv thaiv corrosion zoo heev, thiab tswj cov txheej txheem ntawm cov ntawv txias txias. Siv: Cov khoom siv hauv tsev, rooj plaub hauv computer thiab qee qhov rooj thiab cov vaj huam sib luag.
Kub dip zinc phaj (SGCC): Dip plated, ci dawb, me me zinc paj (nyuaj pom), cov paj zinc loj tuaj yeem pom meej hexagonal paj blocks. Hauv tsev tsuas yog Taiwan Xeev Tuam Tshoj Steel, Shengyu Steel Corporation ob lub chaw tsim khoom tuaj yeem tsim tau, Tuam Tshoj av loj tsis muaj hlau tuaj yeem tsim cov ntaub ntawv zoo, feem ntau vam khom rau kev xa khoom.
Cov yam ntxwv tseem ceeb:
Corrosion kuj, xim tsis kam, formability thiab qhov chaw weldability.
Nws yog dav siv, feem ntau yog rau cov khoom siv hauv tsev me me uas xav tau cov khoom zoo li qub, tab sis piv nrog SECC, nws cov nqi kim dua, yog li ntau lub tuam txhab siv SECC kom txuag tau cov nqi.
Muab faib los ntawm zinc: qhov loj ntawm zinc paj thiab thickness ntawm zinc txheej tuaj yeem piav qhia qhov zoo ntawm zinc plating, qhov me dua qhov thicker dua. Cov neeg tsim khoom kuj tseem tuaj yeem ntxiv kev kho tus ntiv tes tiv thaiv. Tsis tas li, nws tuaj yeem paub qhov txawv ntawm nws cov txheej, xws li Z12, uas txhais tau tias tag nrho cov nyiaj ntawm ob sab txheej txheej 120g / hli.
Piv txwv li:
Aluminized zinc steel phaj (SGLD) : Nws yog cov khoom siv ntau yam uas muaj cov nplua nuj txhuas thiab zinc. Vim yog cov yam ntxwv ntawm txhuas thiab zinc, nws muaj kev ua tau zoo dua li kub dip zinc steel phaj (SGCC). Cov yam ntxwv tseem ceeb: corrosion kuj, uas yog ntau dua li SGCC; Thaum tshav kub kub tsis kam; Thaum tshav kub kub conduction thiab thermal reflection; Formability; Weldability. Siv: Siv nyob rau hauv qee qhov chaw uas yuav tsum tau muaj kev xav zoo, xws li cov phaj reflector hauv qhov cub, lub phaj reflector ntawm lub lauj kaub hluav taws xob. Kub dip zinc steel phaj (SGCC) yog dav siv, aluminized zinc steel phaj (SGLD) yog sib sib zog nqus stamping, SGCE yog super tob stamping.
Kev soj ntsuam zoo
Cov kev xav tau zoo ntawm cov ntawv zoo galvanized muaj xws li ntau yam xws li qhov loj me, qhov chaw, cov nyiaj galvanizing, tshuaj muaj pes tsawg leeg, phaj zoo, tshuab ua haujlwm thiab ntim khoom.
1. pob
Nws tau muab faib ua galvanized ntawv txiav mus rau qhov ntev ntev thiab galvanized ntawv ntim nrog coil. General hlau ntim, lined nrog cov ntawv pov thawj noo noo, nrog lub duav hlau khi, khi ruaj khov, tiv thaiv cov ntawv galvanized sab hauv kev sib txhuam.
2. Specification thiab loj
Cov khoom lag luam cuam tshuam (xws li thiab hauv qab) qhia cov nplai tuab, qhov ntev thiab qhov dav ntawm daim ntawv galvanized lav thiab lawv qhov ua txhaum cai. Tsis tas li ntawd, qhov dav thiab ntev ntawm lub rooj tsavxwm thiab qhov dav ntawm lub ntim kuj tuaj yeem txiav txim siab raws li tus neeg siv qhov kev thov.
3. nto
Qhov xwm txheej dav dav: Vim tias qhov sib txawv ntawm cov txheej txheem kev kho mob hauv cov txheej txheem plating, qhov xwm txheej dav dav ntawm cov phaj galvanized kuj txawv, xws li cov paj zinc zoo tib yam, zoo zinc paj, paj zinc paj, paj dawb zinc thiab phosphating pov tseg profiles. Cov ntawv galvanized thiab galvanized coil txiav mus rau qhov ntev yuav tsum tsis txhob muaj qhov tsis xws luag uas cuam tshuam rau kev siv lub kauj, tab sis cov kauj raug tso cai kom muaj qhov deformed tsawg dua xws li vuam qhov chaw.
4. Galvanized tus nqi
Galvanizing ntsuas tus nqi: Kev ntsuas galvanizing yog ib txoj kev siv dav los txiav txim siab lub thickness ntawm zinc txheej ntawm galvanized ntawv. Muaj ob hom zinc plating nrog tib tus nqi ntawm ob sab (uas yog, sib npaug thickness zinc plating) thiab ob hom zinc plating nrog ntau npaum li cas ntawm ob sab (uas yog, qhov sib txawv thickness galvanized). Chav tsev ntawm galvanizing kom muaj nuj nqis yog g / m2.
5. Tshuab muaj nuj nqi
(1) Tensile test: Feem ntau hais lus, ntev li ntev raws li qhov kev teeb tsa, kos duab thiab kos duab sib sib zog nqus galvanized ntawv muaj tensile muaj nuj nqi.
(2) Kev sim khoov: nws yog lub npe tseem ceeb rau kev ntsuas cov txheej txheem ua haujlwm ntawm cov ntawv hlau. Txawm li cas los xij, cov kev cai rau txhua yam ntawm cov ntawv galvanized hauv ntiaj teb tsis zoo ib yam. Feem ntau, tom qab cov ntawv galvanized yog khoov rau 180o, cov txheej txheej sab nrauv yuav tsum tsis muaj zinc txheej sab laug, thiab cov phaj hauv paus yuav tsum tsis muaj qhov tawg thiab tawg.
6. Tshuaj muaj pes tsawg leeg
Cov kev cai rau cov tshuaj muaj pes tsawg leeg ntawm galvanized substrates sib txawv ntawm lub teb chaws mus rau lub teb chaws nyob rau hauv lub ntiaj teb no. Yog tias Nyiv muaj qhov yuav tsum tau ua, Tebchaws Meskas tsis ua. Feem ntau tsis txhob ua cov khoom kuaj xyuas.
Xya. Phaj puab
Muaj ob lub hom phiaj rau qhov hnyav phaj zoo li dub thiab dawb, uas yog flatness thiab sickle khoov. Lub flatness ntawm lub phaj thiab qhov siab tshaj plaws tus nqi teev ntawm tus kab mob khoov yuav tsum tau txhais.
