1.Vim li cas cov coils zoo tib yam galvanized tsis haum?
Tsis txaus siab siab -Temperature Resistance
Qhov teeb meem tseem ceeb: Thaum lub sij hawm braking, qhov kub siab uas tsim los ntawm kev sib txhuam tuaj yeem ncav cuag 400℃lossis txawm siab tshaj 700 degree.
Tsis muaj zog ntawm Galvanized Txheej: Zinc lub melting point yog kwv yees li 419 degree. Thaum kub kub, txheej galvanized softens, melts, thiab tej zaum yuav vaporize. Qhov no tsis yog tsuas yog ua rau tsis ua haujlwm ntawm cov txheej txheem tiv thaiv -corrosion tab sis, muaj kev phom sij ntau dua:
Kev sib kis ntawm Cov Kev Sib Tw Sib Nqus: Vaporized zinc tuaj yeem cuam tshuam rau lub nres nres thiab cov nres nres, cuam tshuam rau kev ua haujlwm braking.
Gas Generation: Thaum qhov kub thiab txias, qhov no yuav cuam tshuam rau kev sib cuag ntawm lub nres nres thiab lub nres caliper, tsim kom muaj "cushion" cuam tshuam thiab txo qis kev ua haujlwm ntawm braking.
Cov kev xav tau siab heev thiab Rigidity
Nres ncoo thaub qab daim hlau yuav tsum muaj zog heev thiab rigidity los tiv thaiv loj hydraulic clamping thiab shearing rog, tiv thaiv deformation thaum lub sij hawm braking.
Cov khoom siv hauv paus ntawm cov coils zoo tib yam galvanized (feem ntau qis - carbon steel xws li SPCC) yog deb ntawm qhov muaj zog txaus. Nres pad thaub qab daim hlau yuav tsum muaj siab- lub zog steel, thiab qee zaum txawm tias tshwj xeeb tsim cov qib siab -lub zog qis- alloy steel.
Teeb meem Adhesion
Cov khoom sib txhuam ntawm cov ntaub thaiv (qhov dub) yog sib txuas los yog riveted rau lub phaj nraub qaum nyob rau hauv qhov kub thiab txias.
Cov txheej txheej galvanized muaj ib tug du nto thiab hloov pauv ntawm qhov kub thiab txias, uas tuaj yeem cuam tshuam qhov adhesion lub zog ntawm cov khoom sib txhuam thiab cov phaj rov qab. Hauv qhov xwm txheej hnyav, qhov no tuaj yeem ua rau cov khoom sib txhuam kom tshem tawm, ua rau muaj kev nyab xeeb loj heev.
2.Dab tsi yog lub hauv paus phaj ntawm lub nres nres rov qab phaj?
High-lub zog steel / qis- alloy siab- lub zog steel: Qhov no yog qhov kev xaiv tseem ceeb. Los ntawm kev sib ntxiv ntawm microalloying ntsiab lus thiab tswj dov thiab txias txheej txheem, lawv ua tiav lub zog thiab rigidity deb tshaj li qhov qis qis - carbon steel.
Cov khoom yuav tsum tau: High yield zog, siab tensile zog, thiab zoo ductility.
3.Dab tsi yog qhov cuam tshuam ntawm qhov chaw tiv thaiv- kev kho corrosion?
Electrophoresis: Qhov no yog cov txheej txheem ntau tshaj plaws thiab cov txheej txheem tseem ceeb. Cathodic electrophoresis, in particular, provides a uniform, dense, and highly adhesive coating with excellent corrosion resistance. Lub txheej nws tus kheej kuj tuaj yeem tiv taus qhov kub siab ntawm braking.
Dacromet: Ib qho uas tsis yog - tshuaj tiv thaiv kab mob - corrosion txheej tshuab nrog zoo heev tshav kub corrosion kuj, kuj zoo heev haum rau brake pad thaub qab daim hlau.
Phosphating: Feem ntau yog siv los ua pretreatment rau electrophoresis los yog txheej los ua kom txheej adhesion; nws kuj muaj qee yam xeb- tiv thaiv.
Hmoov Txheej / Txau: Siv cov hmoov txheej uas siv siab -kub epoxy resin lossis lwm cov hmoov txheej.
4.Dab tsi yog qhov sib txawv ntawm qhov siab - qhov kub thiab txias ntawm cov coils zoo tib yam galvanized thiab cov neeg ua haujlwm nres nres rov qab daim hlau?
Ordinary galvanized coils tsis zoo siab -kub tsis kam, nrog zinc lub melting point nyob ib ncig ntawm 419 degree; kev ua haujlwm ntawm lub tsheb nres rov qab daim hlau muaj kev ua haujlwm siab tshaj - qhov kub thiab txias (cov khoom siv hauv paus yog hlau, uas muaj lub siab melting point; lub txheej yog kub- tiv taus).
5.Dab tsi yog qhov txawv ntawm cov txheej txheem tiv thaiv -corrosion ntawm cov coils zoo tib yam galvanized thiab cov neeg ua haujlwm nres nres rov qab daim hlau?
Ordinary galvanized coils yog kub-dip galvanized; Cov neeg ua haujlwm nres tsheb rov qab tau kho nrog cathodic electrophoresis, Dacromet txheej, thiab hmoov txheej.
