Long ol hot dip galvanais yok plet ol i yusim long ol pawa transmisin lain, standet implementesen bilong hot-dip galvanizing proses i makim stret sevis laip na sefti pefomens bilong prodak. Dispela atikol bai givim wanpela ditel introdaksen long ol aspek bilong ol proses prinsipel, ol as prosedur, ol ki kwaliti kontrol poin, ol proses advantej, na ol foren tred komplaens standet.
Hot-}dip galvanizing em i as bilong wanpela metalujikel bonding riaksen. Taim wanpela pes i pas wantaim bilong 'steel yoke' i stap insait long 'molten zinc' long samting olsem 450 digri , ain (Fe) insait long 'steel sabstret' na 'zinc' (Zn) insait long zinc ol i wokim long 'molten zinc' i go insait long wanpela 'diffusen' we i wok long go insait long bodi bilong em na i gat 'alloying' riaksen, na dispela i kamapim wanpela tripela bilong 'galvanized leer'. Stat long insait i go aut, ol dispela leit em:
Iron-Zinc Aloy Leya (Ina Leya): Dairekt i pas long steel sabstret, we i gat bikpela hap bilong Fe3Zn10 na FeZn7, em i dens na i gat strongpela pas tru, na givim as garanti bilong korosen resistens na anti{{4}peeling samting bilong galvanais leya.
Zinc-Iron Aloi Leya (Midel Leya): I gat FeZn13, em i gat liklik tiknes na i bungim strong na strong.
Pure Zinc Layer (Outa Leya): Kavremap leja we i stap aotsaed, hem i sofsof mo i daktil, i mekem wan strong film blong protektem zinc oksaed long fes blong hem. Moa yet, sapos i gat ol skrap i stap long ples, em i givim proteksen i go het yet long eria ol i bin skrapim long rot bilong sakrifais anodik proteksen ifek.
Long ol Hot Dip Galvanais Yoke Plets, ol i mas kontrolim strong olgeta tiknes bilong tripela bilong ol tripela-lain straksa bilong stap antap long 65μm. Long ol hai-}rikwaemen aplikesen, ol i ken skruim tiknes i go antap long 85μm long inapim ol nid bilong hai sol sprei na ol envairomen i gat bikpela korosiv.
Prodaksen proses bilong ol Hot Dip Galvanais Yoke Plets i mas bihainim wanpela standet proses bilong pretritmen -} hot{1}}dip galvanisim - post tritmen - inspeksen. Namel long ol, pretritmen em i ki step we i makim kwaliti bilong galvanizing na i afektim stret adhesen na yunifomiti bilong koting.
Degresing tritmen: Yusim wanpela alkaline degresing ejen long sokim long 60-80 digri long 5-10 minit, o yusim hai-}presa sprei klinim long rausim steming oil, ros-preventiv oil, das na oil mak long pes bilong plet i konektim. Ol arere bilong yok plet i gat mak bilong en na ol wol insait long ol hul bilong bolt i stap long ol hap i save stap yet long oil i stap yet, na ol i nidim taim bilong spreim i go longpela o klinim ultrasonik.
wasim na klinim wara: Rinsim long rot bilong wanpela praimeri na sekenderi wara waswas tenk long rausim residuel degresing ejen. Dispela proses i mas mekim na i no gat wanpela wara i bung o i stap yet long ol hul bilong bolt.
Acid pikling na rus rausim: Yusim haidroklorik asit long pik, putim long rum tempereja bilong 10-15 minit long rausim oksait skel, ros, na rolim oksait leit long yok plet pes. Long tikpela oksait skel, taim bilong pikim i ken go longpela moa, tasol strongpela kontrol i mas kamap bilong abrusim pasin bilong kisim planti kaikai tumas, na dispela inap mekim na pes i no gutpela na i no pas gut moa.
Wota was na neutralisasen: Immerse long wanpela alkaline neutralisasen tenk long daunim ol residuel asidik samting, na mekim gut wanpela neutral pes. Ol wol insait long ol hul bilong bolt i mas rinsim gut tru bilong pasim ol samting i stap yet long asit i no ken kamapim blut i stap insait long galvanais leia.
Drying and preheating: Dry at 120-150℃ for 10-15 minutes to completely remove surface moisture. The surface must be free of water stains and oxidation; otherwise, the galvanized layer may show signs of blistering or exposure to oxidized material. Defects such as those mentioned above; Zinc immersion: The zinc immersion temperature is strictly controlled at 445-460℃. The immersion time is adjusted according to the thickness of the plate. When the thickness is ≤6mm, the immersion time is 1-2 minutes. When the thickness is >6mm, taim bilong imersen em 2-3 minit. Koling tritmen: Yusum ea koling o wota mist kolkol blong kolkol i go long rum tempereja. Long taim bilong kol, abrusim ol birua namel long Hot Dip Galvanais Yoke Plets long stopim ol mak long koting.
Long ol Hot Dip Galvanis Yoke Plate ol i bin salim i go aut, proses bilong wokim ol samting i mas inapim ol standet na setifikesen rikwaemen bilong mak maket i stret; sapos nogat, ol bai no inap go insait long maket. Olsem wanpela profesenel kampani bilong wokim ol samting, kampani bilong mipela i putim gutpela samting long gutpela bilong prodak; plis yu no ken pret long baim.
