1. Njira yopangira mbale yachitsulo yamtundu
Mtundu zitsulo mbale (amatchedwanso mtundu mbale, mtundu TACHIMATA zitsulo mbale,pa ppgl) zimachokera ku mbale yazitsulo zozizira, mbale yachitsulo kapena galvalume zitsulo zopangira zitsulo, pambuyo pokonzekera pamwamba (kuchotsa mafuta, kuyeretsa, mankhwala otembenuza mankhwala), ndi zokutira (njira yokutira yodzigudubuza), mankhwala opangidwa ndi kuphika ndi kuziziritsa.
Chophimbacho chimaphatikizapo malaya awiri ndi kuphika kumodzi, malaya awiri ndi ophika awiri, ndi zina zotero.
Njira yayikulu yopangira makina opaka utoto wamitundu iwiri ndi yophika kawiri ndi: makina opukutira ----------------------------------------------- -Uncoiling Looper-----Alkaline Degreasing----Kuyeretsa----Kuyanika------Passivation-----Kuyanika------Kuyambira Coating ------- kuyanika koyamba ndi kuyanika------ topcoat zokutira zabwino------ kuyanika kwa topcoat------ kuzirala kwa mpweya ndi kuziziritsa------ ntchito yokhotakhota Set ----- rewinder----- (the mpukutu wotsatira umapakidwa ndikuyikidwa mu yosungirako).
Magawo wamba a coil zitsulo zokutidwa ndi utoto (ppgi ppgl koyilo)
(1) Chigawo chozizira chozizira
Mbalame yamtundu wopangidwa kuchokera kumtunda wozizira wozizira imakhala ndi maonekedwe osalala komanso okongola ndipo imakhala ndi ndondomeko ya mbale yozizira;komabe, zing'onozing'ono zilizonse pamtunda zidzavumbulutsa gawo lapansi lozizira kwambiri, lomwe lidzawululira chitsulocho mwachangu ku Amapanga dzimbiri lofiira.Choncho, zinthu zoterezi zingagwiritsidwe ntchito pokhapokha pazodzipatula zokhazokha komanso zipangizo zamkati zomwe zili ndi zofunikira zochepa.
(2) Kutentha koviika kanasonkhezereka gawo lapansi
The mankhwala analandira ❖ kuyanika ❖ kuyanika organic paotentha-kuviika kanasonkhezereka koyilondi chinsalu chovimbika chamalatiti opaka utoto.Kuphatikiza pa chitetezo cha nthaka, kupaka kwa organic pamtunda wa pepala lopaka utoto wonyezimira kumakhalanso ndi gawo la kutchinjiriza ndi chitetezo, kuteteza dzimbiri, ndipo moyo wautumiki ndi wautali kuposa wa dip yotentha. pepala lotayirira.Zinc zomwe zili mu gawo lapansi lotentha-dip kanasonkhezereka nthawi zambiri ndi 180g/m2 (mbali ziwiri), ndipo zinki pazipita mu otentha-kuviika kanasonkhezereka gawo lapansi pomanga kunja ndi 275g/m2.
(3) Malo otentha a Al-Zn
Pa pempho, hot-dip galvalume koyiloAtha kugwiritsidwanso ntchito ngati magawo okhala ndi utoto (55% AI-Zn ndi 5% AI-Zn).
(4) Gawo lamagetsi lamagetsi
Pepala lopangidwa ndi electro-galvanized limagwiritsidwa ntchito ngati gawo lapansi, ndipo chopangidwa ndi kupaka utoto wa organic ndi kuphika ndi pepala lopaka utoto lamagetsi.Chifukwa chosanjikiza cha zinc cha pepala lopangidwa ndi ma electro-galvanized ndi woonda, zinc zili ndi 20/20g/m2, kotero mankhwalawa sali oyenera kugwiritsidwa ntchito.Pangani makoma, madenga, etc. panja.Koma chifukwa cha mawonekedwe ake okongola komanso ntchito yabwino yopangira, itha kugwiritsidwa ntchito makamaka pazida zam'nyumba, zomvera, mipando yachitsulo, zokongoletsera zamkati, ndi zina zambiri.
Pamwamba yokutidwa ndi zigawo ziwiri za utoto ndi wosanjikiza wa utoto wokutidwa kumbuyo (mtundu wotere wa kumbuyo nthawi zambiri suyenera kugwiritsidwa ntchito kutsogolo)
Prepainted steel coil (ppgi ppgl) ndi chinthu chopangidwa ndi chitsulo chozizira, chotenthetsera choviyitsa zitsulo kapena mapepala achitsulo a galvalume pambuyo pochotsa mafuta, phosphating ndi chromate mankhwala, kenako zokutira ndi utoto wa organic ndikuwotcha.Zomwe zimagwiritsidwa ntchito popaka mbale zazitsulo zokhala ndi utoto ndi poliyesitala (BHP XRW ❖ kuyanika dongosolo, Baosteel JZ, Korea PGS, Taiwan PE), kutsatiridwa ndi silikoni utomoni (PSS), fluorine utomoni (PVDF), etc. Makulidwe okutira nthawi zambiri amakhala 20-25μ pamwamba ndi 8-10μ kumbuyo.Miyezo yomwe nthawi zambiri imatchulidwa pamapepala opaka utoto ndi American ASTM A527 (galvanized), ASTM AT92 (aluminium-zinc), Japanese JIS G3302, European EN/0142, Korea KS D3506, Baosteel Q/BQB420
