Q: Cov yam ntxwv ntawm Galvalum hlau kauj?
A: corrosion Kuj: cov txheej txheej txhuas
Thaum tshav kub kub ua: lub ntsiab lus melting ntawm txhuas (660 degree) yog siab dua ntawm zinc (419℃ntawm 300℃(xws li ci thiab ci) {4 {4}
Kev ua tau zoo: cov txheej ua tau zoo ua rau lub substrate thiab tuaj yeem hloov kho cov txheej txheem xws li, thiab tsis yooj yim rau tawg lossis poob tawm .
Kev zoo nkauj thiab ua haujlwm: Cov nplaim tuaj yeem ua tau nyiaj-grey xim luster lossis passivated passive (xws li ob qho tib si phooj ywg thiab ib puag ncig zoo.
Q: Cov ntsiab lus tseem ceeb ntawm Galvalum hlau Coils?
A: Txheej hnyav
Chav: grams ib square Meter (G / M²), cov kev qhia tshwj xeeb: 40/60/80/100/120 g / M² (Ob-Sided tag nrho).
Cov siab dua tus nqi, lub zog dua corrosion tsis kam, thiab nws yuav tsum tau raug xaiv raws li kev siv cov ntug dej hiav txwv (.
Substrate Thickness
Ntau yam khoom: {0.15-4.0 mm, nyias cov lus qhia txawv (<0.5mm) are mostly used for home appliances, and thick specifications are used for building structures.
Nto Kho
Passivation: chromium-pub dawb passiveation (ib puag ncig phooj ywg) lossis chromate passivation (tsoos ntiv tes-tiv thaiv dawb thaum muaj kev thauj mus los thiab cia.
Roj txheej: Thov los tiv thaiv xeb roj los txhim kho kev tiv thaiv luv luv (yuav tsum tau ntxuav ua ntej ua tiav).
Q: Cov chaw thov app yog dab tsi?
A: Kev lag luam tsim kev tsim kho: ru tsev panels, phab ntsa ntoo, dov kaw, cua nkoj ua pa; Kev Lag Luam Hauv Tsev: Tub Yees, Lub Tshuab Cua Txias, Tshuab Ntxhua Khaub Ncaws, MICROWVE CUB CAV; Tsheb thiab Tsheb Thauj Mus Los: Tsheb Chassis Qhov Chaw, Tso cov yeeb nkab nkhaus, cov chaw muaj zog loj, ntim; Kev lag luam thiab lwm tus: cov tais cable, cov khoom siv cuab yeej, hnub ci nkhaus
Q: Yuav xaiv li cas raws li cov kev xav tau sib txawv?
A: {1. ib puag ncig ib puag ncig
Sab nraum zoov / siab av / Ntsev Tshuaj Tsuag Ib puag ncig: Muab qhov tseem ceeb rau Galvanized cov kauj nrog ntau dua los yog sib npaug rau 80 g / m².
Nyob sab hauv tsev qhuav: qhov teeb yuag sab hauv tuaj yeem txo (xws li 40-60 g / m²) kom tswj cov nqi.
2. Taug Kev Ua Ntej Tom Ntej
Kev thau duab yuav tsum tau: Xaiv ib substrate nrog txoj kev ua kom haum rau saum npoo av (xws li "ua tiav roughness") kom ntseeg tau tias xim pleev xim .
Sib sib zog nqus stamping: paub meej txog elongation ntawm substrate (ntau dua los yog sib npaug) thiab cov nplaum ntawm cov khoom lag luam (xws li dhau mus xeem ntawv).
3. ib puag ncig ib puag ncig
EU thiab lwm yam kev lag luam yuav tsum ua raws li cov kev cai xws li ROHS thiab ncav cuag, thiab muab cov khoom lag luam chromium-dawb passion.
Q: Cov Qauv Txheej Txheem rau Galvalum Chev?
A: Cov Qauv Thoob Ntiaj Teb: ASTM A792 (Tebchaws Asmeskas), Tebchaws Asmeskas (Tebchaws Europe), JIS G3321 (Nyiv).
Suav Cov Qauv: GB / T 14978-2018
