Ubwino ndi kuipa kwa aluminiyamu-zinki yokutidwa zitsulo mbale

Chitsulo chotenthetsera chotenthetsera chakhala chikugwiritsidwa ntchito kwambiri pomanga, zida zapanyumba ndi mafakitale ena akuluakulu kuyambira pomwe zidawonekera. Chifukwa cha kukula kosalekeza kwa kuchuluka kwa ntchito, mawonekedwe ake ndi zinthu zosiyanasiyana za zinthu zomwe zimapangidwa ku mbale yachitsulo zimasinthidwa mosalekeza, ndipo chitsulo chopangidwa ndi aluminiyamu-zinki chopangidwa ndi chitsulo chimakhala chopambana kuposa mbale yachitsulo yovimbidwa yotentha muzinthu zina. Aluminium-zinc plated zitsulo mbale
Al-Zn composite aluminiyamu-zinc plated zitsulo mbale amapezedwa ndi otentha-kuviika plating ndi ozizira adagulung'undisa zolimba mbale ya mphamvu zosiyanasiyana ndi makulidwe monga mfundo maziko. Chophimbacho chimakhala ndi 55% aluminiyamu, 43.5% zinki, 1.5% silicon ndi zinthu zina.
Popanga ndi kukonza, magwiridwe antchito a aluminiyamu-zinc plating ndi apamwamba kuposa a dip-dip galvanizing, makamaka muzinthu zotsatirazi.
Kukonza magwiridwe
Magwiridwe a aluminiyamu-zinki yokutidwa ndi mbale yachitsulo ndi yofanana ndi yotentha-kuviika galvanizing, yomwe imatha kukwaniritsa zofunikira pakugubuduza, kupondaponda, kupindika ndi mitundu ina.
Kukana dzimbiri
Chiyesocho chimachitika potengera pepala lachitsulo chovimbika chotenthetsera ndi zitsulo zotayidwa ndi zinki zokhala ndi makulidwe omwewo, zokutira ndi chithandizo chapamwamba. Aluminiyamu-zinki plating ali ndi dzimbiri kukana kwambiri kuposa kutentha-kuviika galvanizing, ndipo moyo wake utumiki ndi 2-6 kuwirikiza 2-6 kuposa mbale malata malata.
Kuwala kowunikira
Kuthekera kwa zinc zonyezimira kuwonetsa kutentha ndi kuwala kuwirikiza kawiri kuposa mbale yachitsulo, ndipo chiwonetsero chake ndi chachikulu kuposa 0,70, chomwe chili bwino kuposa 0,65 chofotokozedwa ndi EPA Enerav Star.
Kukana kutentha
Wamba otentha-kuviika kanasonkhezereka mankhwala amagwiritsidwa ntchito pa kutentha osapitirira 230 ℃, ndipo kusintha mtundu pa 250 ℃, pamene mbale zotayidwa-zinki angagwiritsidwe ntchito kwa nthawi yaitali pa 315 ℃ popanda kusintha mtundu. Pambuyo pa maola 120 pa 300 ℃, kusintha kwa mtundu wa aluminiyamu-zinki yokutidwa ndi mbale yachitsulo yomwe imakhala yosagwira kutentha ku Baosteel ndi yotsika kwambiri kusiyana ndi mbale ya aluminiyamu ndi mbale ya aluminiyamu.
makina katundu
Mawotchi a aluminiyamu-zinki opangidwa ndi zitsulo amawonetsedwa makamaka ndi mphamvu zokolola, mphamvu zamakokedwe komanso kutalika. Wamba DC51D kanasonkhezereka mbale zitsulo za 150g/m2 ali ndi mphamvu zokolola za 140-300mpa, mphamvu yamakokedwe 200-330 ndi elongation wa 13-25. Mtengo wa DC51D+AZ
Mphamvu zokolola za aluminized zinki zokutidwa zitsulo pepala ndi 150g/m2 aluminized zinki ndi pakati 230-400mpa, mphamvu wamakokedwe ndi pakati 230-550, ndi elongation njanji ndi pakati 15-45.
Chifukwa zokutira za aluminiyamu-zinki ndizitsulo zolimba kwambiri, zimakhala ndi zabwino zambiri komanso zolakwika zina.
1. Kuwotcherera ntchito
Chifukwa cha kuchuluka kwa makina amakina, kachulukidwe kakulidwe ka gawo lamkati lamkati ndikwabwino, ndipo manganese amakhala ochulukirapo, kotero kuti zinki zotayidwa sizingawotchedwe ndi zowotcherera wamba, ndipo zitha kulumikizidwa ndi ma rivets ndi maphwando ena. Pankhani yowotcherera, mbale yachitsulo yovimbidwa yotentha imachita bwino, ndipo palibe vuto kuwotcherera.
2. Kuyenerera kwa kutentha konyowa konkire
Zomwe zimapangidwa ndi zokutira za aluminiyumu-zinki zimakhala ndi aluminiyamu, yomwe imakonda kukhudzidwa ndi mankhwala pokhudzana ndi konkire ya acidic. Choncho, sikoyenera kwambiri kupanga matabwa apansi.
