Pretreatment E-coat Painting System E-coating Line

Cathodic epoxy electro-coatingndiye chizindikiro cha corrosion resistance. Amagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto ndi magalimoto, amapereka mchere wapamwamba kwambiri, chinyezi komanso kukana kwa cyclic corrosion. Komabe, matekinoloje a cathodic epoxy nthawi zambiri amafuna kuti chovala chapamwamba chitetezedwe ku dzuwa. Zovala zamtundu wa epoxy zimakhala zosavuta kuchokoka komanso kuwonongeka chifukwa cha kuwala kwa dzuwa.

Cathodic acrylic electro-coatingimapezeka mumitundu yosiyanasiyana ya ma glosses ndi mitundu kuti iwonjezere kukhazikika kwakunja, kusungidwa kwa gloss, kusungirako mitundu ndi kuteteza dzimbiri. Zogulitsazi zimagwiritsidwa ntchito ngati chomaliza cha chovala chimodzi m'mafakitale aulimi, udzu ndi dimba, zida zamagetsi, ndi zowongolera mpweya.

Ma electrocoatings a Cathodic acrylic amagwiritsidwa ntchito popanga kukhazikika kwa UV komanso kuteteza dzimbiri pazitsulo zachitsulo (zitsulo) zomwe zimafunidwa. Ma cathodic acrylics amagwiritsidwanso ntchito popanga mitundu yowala.

Njira ya electrocoat ikhoza kugawidwa m'magawo anayi:

• Kuchiza

• Tanki ya E-coat ndi zida zothandizira

• Muzimutsuka

• Kutentha uvuni

Munjira yofananira ndi ma e-coat, magawo amayamba kutsukidwa ndikusinthidwa ndi phosphate conversion coating kuti akonzekeretse gawo la electrocoating. Zigawozo zimaviikidwa mumadzi osambira a penti pomwe magetsi olunjika amayikidwa pakati pa zigawozo ndi electrode ya "counter". Utoto umakopeka ndi gawo lamagetsi ku gawolo ndipo limayikidwa pagawolo. Zigawo zimachotsedwa mu kusamba, kutsukidwa kuti zibwezeretse zolimba za utoto zomwe sizinapangidwe, ndiyeno zimaphikidwa kuti zichiritse utoto.

Asanayambe kujambula filimu yojambula, malo ambiri azitsulo amalandila pretreatment yomwe nthawi zambiri imakhala ndi zokutira zotembenuza.

Njira yopangira pretreatment ya e-coat imakhala ndi izi:

1) Kuyeretsa (gawo limodzi kapena zingapo)

2) Kutsuka

3) Conditioning

4) Kutembenuka ❖ kuyanika

5) Kutsuka

6) Pambuyo pa chithandizo

7) Kutsuka madzi osungunuka.

Njira za phosphating zitha kugawidwa m'mitundu iwiri: iron phosphate ndi zinc phosphate. Iron phosphate yakhala njira yosankhira ntchito pomwe kuganiziridwa kwa mtengo wonse kumaposa kufunikira kwa magwiridwe antchito. Popeza ma phosphates a iron ndi zokutira zoonda kuposa ma phosphates a zinc ndipo amakhala ndi ayoni wachitsulo wa gawo lapansi lomwe akukonzedwa, amachepetsa kukana kwa dzimbiri poyerekeza ndi dongosolo la zinc phosphate. Komabe, zoletsa zachilengedwe zikuchulukirachulukira pokhudzana ndi zitsulo zolemera, zokutira zachitsulo za phosphate zophatikizidwa ndi chithandizo chanthawi zonse zimatha kupereka njira ina yabwino mukakumanabe ndi zomwe zikufunika kuti dzimbiri. Ma phosphates a Zinc akhala njira yabwino yopangira zopangira zopangira zitsulo, makamaka pogwiritsa ntchito makina opaka utoto wamagetsi. Chifukwa chake ndikuti amapereka kukana kwa dzimbiri bwino komanso kumamatira utoto kuposa ma phosphates achitsulo pansi pamikhalidwe yovuta kwambiri.
