1.Vim li cas txias -rolled coils haum rau photovoltaic bracket connectors?
Zoo heev muaj zog thiab nruj
Cov txheej txheem txias dov qhia txog kev ua haujlwm hardening, ua kom cov khoom muaj zog (yield zog thiab tensile lub zog) piv rau kub -rolled coils ntawm tib qib. Qhov no yog ib qho tseem ceeb heev rau cov connectors uas ris qhov hnyav ntawm photovoltaic modules, cua loads, thiab daus loads.
Feem ntau siv cov qib steel yog siab - steels muaj zog xws li Q235B, Q355B, thiab siab dua, uas tuaj yeem paub zoo dua lawv lub peev xwm los ntawm kev txias txias.
Zoo Nto Zoo thiab Dimensional raug
Smooth Surface: Txias-rolled coils muaj ib tug du nto tsis muaj hlau oxide nplai, uas ua rau ib tug high℃ntawm tiav. Qhov no tsis yog tsuas yog txhim kho kev zoo nkauj xwb tab sis kuj tseem muab lub hauv paus zoo rau kev tiv thaiv tom ntej - corrosion coatings (xws li kub-dip galvanizing), kom ntseeg tau tias muaj xim zoo nkauj thiab ruaj khov adhesion.
Uniform Thickness thiab Me Tolerances: Cov txheej txheem txias dov ua cov hlau phaj nrog cov tuab tuab thiab tuab, ua kom muaj kev sib xws hauv kev sib txuas ua ke thiab ua kom yooj yim ntau lawm thiab ntawm - qhov chaw teeb tsa.
Zoo heev Machinability thiab Formability
Connectors feem ntau yuav tsum tau ua rau hauv cov duab nyuaj los ntawm stamping, dabtsi yog khoov, drilling, thiab lwm yam txheej txheem.
Txias-rolled coils muaj cov yas zoo thiab tsim tau zoo, thiab tuaj yeem khoov tau yooj yim (xws li kev tsim cov ribs thiab curling npoo) thiab xuas nrig ntaus tsis yooj yim tawg.
2.Dab tsi yog cov txheej txheem ntawm kev thov?
Cov Khoom Raw: Yuav cov khoom txias- dov steel coils ua raws li cov qauv (xws li GB / T 700, GB / T 1591), feem ntau yog qib Q355B, nrog lub thickness ntawm 2.0mm thiab 5.0mm, nyob ntawm seb cov qauv tsim.
Uncoiling, Leveling, thiab Shearing: Uncoil steel coils, theem lawv (kom txhim kho flatness), thiab txiav lawv mus rau hauv cov nplooj ntawv ntawm qhov yuav tsum tau muaj.
Kev Tsim thiab Kev Ua Haujlwm: Siv cov kab ntau lawm rau kev xuas nrig ntaus, blanking, sib sau, khoov, thiab lwm yam, los tsim ntau yam khoom sib txuas.
Kev tiv thaiv corrosion: Kub-dip galvanize cov txheej txheem txuas. Qhov no yog cov kauj ruam tseem ceeb tshaj plaws; galvanized txheej thickness feem ntau yuav tsum tau ntau tshaj los yog sib npaug rau 65μm (thicker tej zaum yuav tsum tau nyob rau hauv tej qhov chaw) kom paub meej ntev -lub sij hawm corrosion kuj.
Kev soj ntsuam zoo thiab ntim: Tshawb xyuas qhov ntev thiab galvanized txheej thickness, ces pob thiab nkoj.
3.Nws zoo li cas piv rau kub- dov kauj?
Kub-rolled coils muaj oxide nplai rau ntawm lawv qhov chaw thiab lub thickness loj dua, thiab feem ntau yog siv rau cov khoom siv xws li cov kab teeb tseem ceeb (C/Z-} zoo li cov hlau) qhov chaw thiab qhov loj me yuav tsum tsis siab, tab sis qhov yuav tsum tau muaj zog ntau dua. Rau cov connectors, precision thiab tsos yog qhov tseem ceeb, yog li txias -rolled coils yog superior.
4.Yuav ua li cas txias - dov kauj piv rau aluminium alloy?
Aluminium alloys yog lub teeb yuag thiab corrosion- tiv taus, tab sis lawv kim dua thiab muaj zog qis dua (tshwj xeeb yog nruj). Rau qhov tseem ceeb, thauj khoom-cov kabmob sib txuas, siab- lub zog steel (txias- dov thiab galvanized) muaj qhov zoo dua qhov sib npaug ntawm tus nqi, lub zog, thiab kev ntseeg tau.
5.Yuav ua li cas txias - dov coils piv rau stainless hlau?
Stainless hlau muaj qhov zoo corrosion kuj, tab sis nws yog kim thiab nyuaj rau txheej txheem. Nws yog tsuas yog siv nyob rau hauv cov xwm txheej uas yuav tsum muaj huab cua tiv thaiv corrosion (xws li corrosive ntug hiav txwv ib puag ncig) los yog cov kev cai tshwj xeeb zoo nkauj, thiab tsis yog qhov kev xaiv nrov.
