Pretreatment E-uwe mkpuchi Sistemụ E-nkpuchi Line

Cathodic epoxy electro mkpuchibụ akara maka nguzogide corrosion. A na-eji ya eme ihe na ụlọ ọrụ ụgbọ ala na nke akpaaka, ha na-enye nnu nnu dị elu, iru mmiri na nguzogide corrosion cyclic. Agbanyeghị, teknụzụ cathodic epoxy na-achọkarị uwe elu ka echebe ya pụọ ​​na ìhè anyanwụ. Ihe mkpuchi ụdị epoxy na-esi ísì ụtọ na-adịkarị mfe ịta chalk na mmebi site na akụkụ UV nke ìhè anyanwụ.

Cathodic acrylic electro mkpuchidị n'ụdị dị iche iche nke glosses na agba iji mee ka ogologo oge dị n'èzí dịkwuo elu, njide gloss, njide agba na nchebe corrosion. A na-eji ngwaahịa ndị a emecha otu uwe n'ime ugbo, ahịhịa na ubi, ngwa na ụlọ ọrụ ntụ oyi.

Cathodic acrylic electrocoatings na-ejikarị na ngwa ebe ma UV anwụ ngwa ngwa na corrosion nchebe na ferrous substrates (steel) chọrọ. A na-ejikwa acrylics cathodic na ngwa ebe a na-achọ agba ọkụ.

Enwere ike kewaa usoro electrocoat na ngalaba anọ dị iche iche:

• ọgwụgwọ mbụ

• E-coat tank na ihe enyemaka

• Biputere sachaa

• Ịgwọ oven

N'ime usoro e-coat a na-ahụkarị, a na-ebu ụzọ hichaa akụkụ ahụ ma jiri mkpuchi ngbanwe phosphate dozie akụkụ ahụ maka electrocoating. A na-etinyezi akụkụ ahụ n'ime bat agba ebe a na-etinye aka ozugbo n'etiti akụkụ ahụ na electrode "counter". A na-adọta agba site na ọkụ eletrik na akụkụ ahụ ma tinye ya na akụkụ ahụ. A na-ewepụ akụkụ na bat ahụ, na-asacha ya iji nwetaghachi ihe siri ike agba na-enweghị ego, wee sie ya iji gwọọ agba.

Tupu itinye ihe nkiri agba, ọtụtụ n'elu igwe na-enweta ọgwụgwọ nke na-agụnyekarị mkpuchi ngbanwe.

Usoro ọgwụgwọ mbụ maka e-coat nwere usoro ndị a:

1) ihicha (otu ma ọ bụ karịa nkebi)

2) Ntucha

3) Nkwado

4) mkpuchi mgbanwe

5) Ntucha

6) Mgbe ọgwụgwọ gasịrị

7) Deionized mmiri rinsing.

Enwere ike kewaa usoro phosphating n'ime ụdị abụọ: ígwè phosphate na zinc phosphate. Iron phosphate abụrụla usoro nhọrọ maka ngwa ebe nleba anya ọnụ ahịa zuru oke na-emebi mkpa arụmọrụ. Ebe ọ bụ na ígwè phosphates bụ ihe mkpuchi dị gịrịgịrị karịa zinc phosphates ma nwee naanị ion metal nke mkpụrụ a na-edozi, ha na-eme ka nkwụsị nke corrosion belata ma e jiri ya tụnyere usoro zinc phosphate. Agbanyeghị, na mmachi gburugburu ebe obibi na-esiwanyewanye ike n'ihe gbasara ọla dị arọ, mkpuchi iron phosphate yana yana ọgwụgwọ post nke ọma nwere ike inye ụzọ dị mma ka ọ na-ezute nkọwa corrosion chọrọ. Zinc phosphates aghọwo ọgwụgwọ prepaint a na-ahọrọ na ụlọ ọrụ na-emecha ọla, karịsịa site na iji usoro agba electrocoat. Ihe kpatara ya bụ na ha na-enye nguzogide corrosion ka mma na nrapado agba karịa ígwè phosphates n'okpuru ọnọdụ ndị na-achọsi ike karị.
