GI Galvanized Steel Coil ee Waxqabadka Sare leh waa wax soo saar bir ah oo aasaasi ah oo loogu talagalay codsiyada warshadaha u baahan iska caabin daxalka adag, xoogga farsamada, iyo waafaqsanaanta nidaamka. Waxaa lagu soo saaray habka galvanizing-kuleelka, gariiraddan waxay ka kooban tahay daahan zinc qaro weyn leh (Z180-Z275g) oo ku yaal substrate bir-kaarboon-yar (Q235, SS400), oo siinaya difaac heersare ah oo ka hortagga qoyaanka, shucaaca UV, iyo wasakhowga hawada.
Waxaa lagu heli karaa dhumucdiisu tahay 0.5mm ilaa 4.0mm iyo ballac ilaa 1500mm, gariiradda ayaa loo habeeyay samaynta hawl culus ee dhismaha, baabuurta, iyo warshadaha mishiinada. Habka kuleylku wuxuu hubinayaa isku xirnaanta birta ee u dhaxaysa zinc iyo birta, abuurista lakab waara oo iskiis u bogsiiya xagashada yaryar iyada oo loo marayo ilaalin allabari.
Astaamaha
Ilaalinta Daxalka Adag :
Z180-Z275 Coating : Waxay ku habboon tahay jawiga dibadda / warshadaha (Z180: kaabayaasha magaalooyinka, Z275: dhirta xeebaha / kiimikaad), oo leh cimri dherer ah 15-30 sano oo ku xiran dayactirka (tusaale, kormeer sanadeedka).
Ilaalinta Allabaryada : Lakabka Zinc wuxuu ka doorbidaa birta, isagoo ilaalinaya cidhifyada go'ay iyo xagashada ilaa lagu hagaajiyo rinjiga zinc-ka leh (tusaale, Zincalume Rinjiga Caalamiga ah).
Guryaha Makaanikada ee Darajada Warshadaha :
Awood wax-soo-saar sare (235-400 MPa) waxay taageertaa codsiyada qaabdhismeedka sida alwaaxyada birta, qaybaha buundada, iyo xirmooyinka mishiinada culus (tusaale, matoorka diirka ee fuula).
Weldability heer sare ah (kaarboonka yar ee ≤0.20%) iyo qaabaynta, oo leh sagxadaha aan spangle-la'aanta lahayn ee awood siinaya alxanka TIG/MIG saxda ah ee kala goysyada muhiimka ah (tusaale, isku xirka barxadaha badda).
Waafaqsanaanta Habraaca :
Ku habboon koronto-samaynta, daahan budada ah, iyo rinjiyeynta dareeraha ah, oo leh pretreatment chromate ikhtiyaari ah oo kor u qaadaysa ku-xidhka rinjiga 40% (tusaale, daahannada warshadaha AkzoNobel).
Miisaannada gariiradda waaweyn (10-20 tan) waxay yareeyaan wakhtiga hoos u dhaca ee khadadka wax soo saarka xawaaraha sare leh, oo leh jeexid gaar ah oo la heli karo ballacyada saxda ah (dulqaad: +/- 0.5mm ee 1000mm+ ballac).
U Hogaansanaanta Heerarka Caalamiga ah :
Buuxiyay ASTM A653 (G90), JIS G3302 (SGCC), iyo EN 10142 (Z275) heerarka, hubinta joogtaynta tayada wax iibsiga caalamiga ah (tusaale, mashaariicda kaabayaasha UAE, hawlaha macdanta Brazil).
100% dib loo warshadayn karo dhamaadka nolosha, iyadoo heerarka soo kabashada zinc ay ka badan tahay 95%, oo la jaan qaadaya mabaadi'da dhaqaalaha wareega.
Codsiga
Dhismaha & Kaabayaasha : Waxay warshadeeyaan I-beams, qaybaha kanaalka, iyo saqafka saqafka ee dhismayaasha ganacsiga (tusaale, Dubai Mall balaadhinta), buundooyinka (tusaale, San Francisco-Oakland Bay Bridge), iyo warshado koronto (tusaale, Saudi Aramco).
Gawaarida & Gaadiidka : Waxay sameeyaan qaybaha chassis-ka, foomamka xamuulka, iyo faashashka gawaarida ee baabuurta culus (tusaale, Volvo FH), oo bixiya ilaalinta milixda wadada iyo walbahaarka farsamada.
Mashiinada Warshadaha : Waxaa loo isticmaalaa qalabka wax soo saarka, hababka gudbinta, iyo haamaha kaydinta macdanta (tusaale, BHP Billiton ore processing), beeraha (tusaale, John Deere isku darka), iyo qaybaha wax soo saarka.
Qaybta Tamarta : Waxay ku habboon tahay saldhigyada marawaxadaha dabaysha (tusaale, beeraha dabaysha ee Vestas), dhejinta muraayadaha qorraxda, iyo dhismayaasha tamarta xeebaha, oo leh daahan AZ150 daahan (ikhtiyaar) kor u qaadaya iska caabbinta kulaylka ee codsiyada qorraxda.
FAQ
S: Sidee bay galvanizing-ku-kulul u barbardhigaan koronto-galvanization?
A: Kuleyl-kululku wuxuu bixiyaa dhumuc weyn, dahaar aad u adkeysi badan (30-275g / m²) ee isticmaalka dibadda; electro-galvanizing (10-20g/m²) waa ka khafiifsan yahay oo ku haboon codsiyada gudaha gudaha sida qalabka alaabta guriga.
S: Gariiradan ma loo isticmaali karaa kaydinta biyaha la cabbi karo?
J: Maya, xiriir toos ah oo lala yeesho biyaha la cabbo waxay u baahan tahay agab-cunto sida birta aan-xawaaraha lahayn ama birta epoxy-lined; Birta GI waxay ku habboon tahay taangiyada biyaha ee aan la cabbi karin iyo hababka waraabka.
S: Waa maxay habka ugu wanagsan ee meesha looga saaro miisanka shiidka ka hor rinjiyeynta?
J: Isticmaal qarxinta nabarrada (cidda/ rasaasta qarxinta) si aad u gaadho astaanta sare ee Sa2.5, iyada oo hubinaysa ku-dhejinta rinjiga ugu fiican ee cimri dhererka.
S: Sida loo xaqiijiyo miisaanka dahaadhka goobta iyada oo aan waxyeello loo geysan gariiradda?
J: Isticmaal qiyaasta dhumucda birlabeedka (tusaale, Fischer XDL) si aad u cabbirto dhumucda dahaarka oo aan burburin; qiyamku waa inuu ku jiraa 5% miisaanka daahan ee la cayimay.
