Hauv tsev
1. Cov qauv khoom siv
Lub hauv paus khoom ntawm aluminium alloy laj kab yuav tsum ua raws li cov kev cai ntawm GB / T 5237.6-2017 Aluminium Alloy Tsev Profiles Ntu 6: Thermal rwb thaiv tsev Profiles, xav tau ib tug magnesium (Mg) cov ntsiab lus ntawm 0.45% ~ 0.9% thiab ib tug silicon (Si) cov ntsiab lus ntawm 0.2%Data tswj lub teb chaws qhov chaw: 6%. Lub zog tensile yuav tsum siab dua los yog sib npaug rau 160MPa, thiab Webster hardness Ntau dua los yog sib npaug rau 8HW kom ntseeg tau tias cov khoom siv tshuab txaus.
2. Kev tiv thaiv corrosion thiab kev kho deg
Raws li GB 5237.5-2017 Aluminium Alloy Tsev Profiles Ntu 5: Painted Profiles, txheej txheej thickness ntawm lub laj kab yuav tsum ua tau raws li cov hauv qab no:
Hmoov txheej Ntau dua lossis sib npaug li 40μm
Fluorocarbon txheej Ntau dua los yog sib npaug rau 30μm (Sab nraum qhov yuav tsum tau muaj)
Kev ntsuas ntsev ntsev yuav tsum dhau 1000 teev yam tsis muaj blistering lossis tev (Saib rau GB / T 10125-2021).
3. Cov qauv kev nyab xeeb Specifications
Txawm hais tias GB 50755-2012, Txoj Cai rau Kev Tsim Kho ntawm Cov Hlau Hlau, tshwj xeeb tshaj yog hais txog cov qauv hlau, Tshooj 4.3 qhia meej meej txog qhov yuav tsum tau ua rau cov khoom siv txhuas alloy guardrails:
Kab rov tav load Ntau dua lossis sib npaug li 1.0 kN / m (cov tsev nyob)
Vertical load Ntau dua lossis sib npaug li 1.2 kN / m (cov vaj tsev pej xeem)
