Hluav taws xob-galvanizing,kuj hu ua txias galvanizing, yog txawv kiag li los ntawm txias galvanizing nyob rau hauv cov nqe lus ntawm ntau lawm txheej txheem, txheej, corrosion tiv thaiv, sib dhos, nqi, thiab siv scenarios.Handan Jihao Fastenersyuav qhia nws los ntawm cov ntsiab lus hauv qab no.
I. Txheej Txheem Ntau Lawm (Qhov txawv ntawm qhov tseem ceeb)
1. Kub-dip galvanizing
Tom qab cov bolts yog degreased thiab derusted, lawv yog immersed nyob rau hauv molten zinc ntawm 450 ~ 500 degree. Cov zinc reacts nrog cov hlau hauv cov txheej txheem metallurgical los ua zinc- hlau alloy txheej, thiab txheej thiab cov substrate yog fused ua ke.
-High-kev ua haujlwm kub tuaj yeem ua rau zinc nodules thiab drips, thiab zinc tuaj yeem yooj yim sau rau ntawm cov xov.
-Qhov kub ua haujlwm siab yuav tsum muaj kev siv siab - lub zog bolts ntawm qib 10.9 thiab siab dua, vim tias qhov kub thiab txias tuaj yeem txo lub zog ntawm cov hlau thiab ua rau muaj kev pheej hmoo ntawm hydrogen embrittlement.
2. Electro-galvanizing
Chav tsev kub electrolysis txheej txheem: Bolts tau muab tso rau hauv zinc ntsev electrolyte, thiab ib qho hluav taws xob tam sim no yog siv los tso cai zinc ions tso rau saum npoo. Qhov no yog lub cev nkaus xwb adsorption, tsis muaj txheej txheej alloy.
-Tag nrho cov txheej txheem yog ua los ntawm qhov kub thiab txias, tsis muaj kev puas tsuaj rau lub zog ntawm lub bolt substrate.
-Cov txheej yog sib xws thiab zoo, thiab cov xov loj tseem yuav luag tsis hloov.
-Electroplating yog yooj yim rau hydrogen permeation; yog li ntawd, 8.8 / 10.9 qib siab - lub zog bolts yuav tsum tau txais kev kho hydrogen ntxiv, txwv tsis pub lawv yuav tawg.
II. Kev sib piv ntawm zinc txheej thickness, tsos, thiab adhesion
| Cov khoom sib piv | Kub-dip galvanized bolts | Electroplated galvanized bolts |
|---|---|---|
| Zinc txheej thickness | Lub teb chaws tus qauv Ntau dua lossis sib npaug rau 55μm, tus qauv 60 ~ 100μm, ntug hiav txwv / sab nraum zoov Ntau dua lossis sib npaug rau 85μm Chongqing scorching khoom | Cov txheej tsuas yog 5 ~ 15μm tuab, nrog qhov siab tshaj plaws thickness tsis ntau tshaj 25μm, ua rau nws nyias nyias. |
| Nto zoo li | Greyish-dawb, matte thiab ntxhib, nrog zinc spangles, zinc spikes, thiab pob; tag nrho cov tsos yog zoo tib yam. | Ci ntsa iab thiab du, nws tuaj yeem ua los ntawm zinc dawb, xim zinc, lossis zinc dub, thiab muaj cov khoom zoo nkauj zoo nkauj. |
| Txheej adhesion | Metallurgical bonding tiv thaiv zinc tsis yooj yim poob thaum muaj kev cuam tshuam thiab khoov. | Cov xeb tsuas yog txuas nrog lub cev; nws yog nthuav los ntawm tsuas yog tig ib tug ciaj ntswj los yog me ntsis kev sib txhuam. |
| Hnav tsis kam | High- txheej zoo yog ruaj thiab hnav-resistant | Lower txheej thickness yog feem ntau hnav. |
| nqi | Ntau dua thiab ua haujlwm ntev dua | Txo cov nqi ua haujlwm thiab kev lag luam |
| Anti-cov khoom tiv thaiv corrosion | Zoo heev, haum rau sab nraum zoov thiab corrosive ib puag ncig. | Feem ntau, nws tsim nyog rau qhov chaw qhuav lossis sab hauv tsev. |
III. Corrosion Resistance
1. kub dip galvanized
-Kev tiv thaiv ob npaug: tuab zinc txheej cais + kev tiv thaiv kev txi anode; Txawm hais tias cov txheej yog khawb, cov zinc nyob ib puag ncig yuav nyiam corrode thiab tiv thaiv cov hlau.
-Kev ntsuam xyuas ntsev: Cov txheej txheem 85μm txheej tuaj yeem tiv taus ntau dua 1000 teev yam tsis muaj xeb liab; nws tuaj yeem siv sab nraum zoov thiab hauv thaj chaw ntug dej hiav txwv rau 10 txog 20 xyoo lossis ntau dua.
2.Electro galvanized
- Tsuas yog ib txheej nyias ntawm zinc rau kev tiv thaiv, kev tiv thaiv kev txi yuav luag tsis muaj txiaj ntsig; Thaum cov txheej txheem puas lawm, cov hlau yuav xeb tam sim ntawd.
-Cov xim zoo tib yam zinc ntsev tshuaj tsuag cov txiaj ntsig tsuas yog 72-200 teev; loj-chaw xeb tshwm sim nyob rau hauv ib puag ncig sab nraum zoov tsis pub dhau 1-2 xyoos, ua rau nws tsuas yog haum rau qhuav nyob rau hauv ib puag ncig.
IV. Muaj cov xwm txheej
1.Kub-dip galvanized bolts
-Cov qauv hlau sab nraum zoov: txuas hniav, kev txhawb nqa photovoltaic, cua tshuab hluav taws xob, cov kav xa hluav taws xob, cov teeb pom kev, kev tiv thaiv
-Cov tshuaj tsuag ntsev ntawm ntug dej hiav txwv, thaj chaw muaj kua qaub thiab alkali, cov cuab yeej faus, cov khoom siv fais fab
-Cov phiaj xwm uas nthuav tawm rau lub sijhawm txuas ntxiv thiab nyuaj rau khaws cia tom qab.
2.Electroplated galvanized bolts
- Cov khoom siv sab hauv tsev, cov txee, khoom siv rooj tog, thiab cov khoom vaj khoom tsev
-Cov tshuab precision, cov khoom sib dhos me me, thiab cov khoom uas yuav tsum tau ua kom zoo
- ib puag ncig ntawm lub Hoobkas qhuav, los nag-dawb thiab ntsev tsuag- pub dawb hauv tsev ua haujlwm
V. Cov ntsiab lus ntawm qhov zoo thiab qhov tsis zoo
1.Kub-dip galvanized bolts
Qhov zoo: zoo heev corrosion kuj, lub neej ntev kev pab cuam, muaj zog txheej, thiab cuam tshuam tsis kam.
Qhov tsis zoo: Cov nplais ntxhib, xav tau cov txiv ntseej tshwj xeeb rau cov xov, kim, tsis haum rau ultra- lub zog siab bolts ntawm qhov kub thiab txias.
2.Electroplated galvanized bolts
Qhov zoo: Ci ntsa iab thiab zoo nkauj tsos, cov xov zoo haum, meej qhov ntev, tus nqi qis
Qhov tsis zoo: Cov xeb tsis zoo, plating tau yooj yim hnav, luv luv - lub sij hawm xeb sab nraum zoov, siab - qhov chaw muaj zog muaj kev pheej hmoo hydrogen embrittlement.
