Chithunzi cha SPCCmbale yachitsulo
SPCC zitsulo mbale ndiozizira adagulung'undisa mpweya zitsulo mbaleotchulidwa mu Japanese Industrial Standard (jis g 3141).Dzina lake lonse ndi "chitsulo mbale ozizira adagulung'undisa malonda khalidwe", kumene spcc amaimira makhalidwe ndi ntchito mbale zitsulo: s akuimira chitsulo., p amatanthauza mbale yathyathyathya, c amatanthauza kalasi yamalonda, ndipo c yotsiriza imatanthauza kuzizira kozizira.Chitsulo ichi ndi mbale yachitsulo ya carbon yochepa yomwe nthawi zambiri imagwiritsidwa ntchito popanga zigawo za firiji zatsopano, mafiriji ocheperako kapena malamba otumizira magalimoto.Chitsulo ichi chili ndi mawonekedwe abwino kwambiri opangira ndi kupondaponda, ndipo amatha kukonzedwa ndi kupondaponda kozizira kwambiri.Chifukwa chokhala ndi mpweya wochepa kwambiri, zimakhala ndi makina osowa koma zimakhala ndi pulasitiki yabwino, zomwe zimapangitsa kuti zikhale zosavuta komanso zosavuta kuzipanga kukhala zazikulu.Ngakhale mbale yachitsulo ya spcc siyoyenera kugwiritsa ntchito zomwe imafuna mphamvu zambiri, imagwiritsidwabe ntchito kwambiri m'mafakitale ambiri monga zida zapakhomo ndi magalimoto.Panthawi imodzimodziyo, zinthuzi zimakhalanso ndi zotsutsana kwambiri ndi dzimbiri ndipo zimagwiritsidwa ntchito kwambiri nthawi zina zomwe zimakhala zofunikira kwambiri.
The pamwamba mankhwala a spcc zitsulo mbale zikhoza kuchitika m'njira zambiri.Nazi njira zodziwika bwino:
Kuyeretsa pamakina: Gwiritsani ntchito zida monga maburashi a waya kapena sandpaper kupukuta ndi kutsuka pamwamba pochotsa litsiro monga dzimbiri ndi mafuta.
Kuchiza ndi mankhwala: kugwiritsa ntchito asidi, alkali kapena mankhwala enaake kuti asungunuke kapena kusintha ma oxide apamtunda kapena zonyansa zina kukhala zinthu zoyeretsedwa kuti akwaniritse cholinga choyeretsa pamwamba.
Kuchiza kwa Electroplating: Kuyika kwachitsulo kumapangidwa pamwamba pa mbale yachitsulo kudzera mu electrolysis kuti apange wosanjikiza wazitsulo zoteteza kuti zithandizire kukana komanso mawonekedwe ake.
Chithandizo cha zokutira: Uzani utoto wamitundu yosiyanasiyana pamwamba pa mbale yachitsulo ya spcc kuti musewere ntchito zoletsa dzimbiri ndi kukongoletsa.
Njira zosiyanasiyana zochizira pamwamba ndizoyenera pazosowa zamakampani osiyanasiyana.Kusankha njira yoyenera kuchitira pamwamba pa spcc zitsulo mbale malinga ndi mmene zinthu zilili akhoza kukulitsa moyo wake utumiki ndi kukhala ndi makhalidwe abwino makina.
Chithunzi cha SECC
Dzina lonse la SECC ndi Steel, Electrolytic Zinc-coated, Cold Rolled Steel Coil, yomwe ndi mbale yachitsulo yomwe imapangidwa ndi magetsi pambuyo pakugudubuzika kozizira.Pamwamba pake ndi electrolytically galvanized kuti ikhale ndi ntchito yabwino yotsutsa dzimbiri komanso kukongola.Nthawi zambiri amagwiritsidwa ntchito popanga zinthu zokhala ndi magwiridwe antchito ochepa odana ndi dzimbiri komanso zofunikira zokongoletsa, monga zida zapanyumba, zida zopangira zida, ndi zina.
Njira ya SECC galvanizing:
Koyela Woviikidwa Wotentha Woviikidwa: Hot-dip galvanizing ndi mankhwala odana ndi dzimbiri omwe amapanga zinki pamwamba pazitsulo.Ndiko kumiza mbale zachitsulo kapena zigawo zachitsulo mumadzi osungunula a zinki omwe amatenthedwa ndi kutentha koyenera (nthawi zambiri 450-480 digiri Celsius), ndikupanga zokutira zokhuthala ndi zokhuthala za zinki-chitsulo pamwamba pazigawo zachitsulo pochitapo kanthu.Tetezani zitsulo kuti zisachite dzimbiri.Poyerekeza ndi galvanizing electrolytic, otentha-kuviika galvanizing ali apamwamba kukana dzimbiri ndi moyo wautali utumiki, ndipo nthawi zambiri ntchito kupanga zinthu zofunika monga structural zigawo zikuluzikulu, zombo, milatho, ndi zipangizo magetsi.
Njira yopititsira malata: Zitsulo zopindidwa zimamizidwa mosalekeza mubafa loyatsira lomwe lili ndi zinki zosungunuka.
Njira yopangira malata: Chitsulo chodulidwa chimamizidwa m'bafa yoyatsira, ndipo padzakhala phala la zinki pambuyo pa plating.
Electroplating njira: electrochemical plating.Pali zinki sulphate yankho mu plating thanki, ndi zinki monga anode ndi choyambirira chitsulo mbale monga cathode.
SPCC vs SECC
SECC kanasonkhezereka zitsulo pepala ndi SPCC ozizira adagulung'undisa zitsulo pepala ndi zipangizo ziwiri zosiyana.Pakati pawo, SECC imatanthawuza ma electrolytically galvanized ozizira adagulung'undisa zitsulo, pamene SPCC ndi waponseponse ozizira adagulung'undisa pepala zitsulo muyezo.
Kusiyana kwawo kwakukulu ndi:
Katundu wakuthupi: SECC ili ndi zokutira zinki ndipo imakhala yabwino kukana dzimbiri;SPCC ilibe anti-corrosion layer.Chifukwa chake, SECC ndi yolimba kuposa SPCC ndipo imateteza dzimbiri ndi dzimbiri.
Chithandizo chapamwamba: SECC yakhala ikuchita galvanizing electrolytic ndi njira zina zochizira, ndipo ili ndi digirii yokongoletsera ndi kukongola;pomwe SPCC imagwiritsa ntchito njira yoziziritsa yozizira popanda chithandizo chapamwamba.
Kugwiritsa ntchito mosiyanasiyana: SECC nthawi zambiri imagwiritsidwa ntchito popanga magawo kapena ma casings m'minda ya zida zamagetsi, magalimoto, ndi zida zapakhomo, pomwe SPCC imagwiritsidwa ntchito kwambiri m'mafakitale monga zomangamanga, kupanga, ndi kuyika.
Mwachidule, ngakhale kuti zonsezi ndi zitsulo zozizira zozizira zomwe zimagwiritsidwa ntchito pazigawo za ndondomeko, pali kusiyana kwakukulu kwa anti-corrosion properties, mankhwala apamwamba ndi ntchito.Kusankhidwa kwa mbale yachitsulo ya SECC kapena SPCC kuyenera kutsimikiziridwa malinga ndi momwe zinthu zilili, poganizira zinthu zosiyanasiyana monga kugwiritsa ntchito mankhwala omwe amapangidwa, chilengedwe ndi zosowa zenizeni, ndikusankha zinthu zoyenera kwambiri.
