Pretreatment E-coat Painting System E-coating Line

Cathodic epoxy electro-coatingʻo ia ka hōʻailona no ka pale ʻana i ka corrosion. Hoʻohana nui ʻia i nā ʻoihana kaʻa a me nā ʻāpana kaʻa, hāʻawi lākou i ka paʻakai paʻakai kiʻekiʻe, ka haʻahaʻa a me ke kūpaʻa corrosion cyclic. Eia nō naʻe, ʻo nā ʻenehana cathodic epoxy maʻamau e koi i ka topcoat e pale ʻia mai ka lā. ʻO nā uhi ʻano epoxy ʻaʻala he mea maʻalahi loa i ka chalking a me ka hōʻino ʻia e nā ʻāpana UV o ka lā.

Cathodic acrylic electro-coatingloaʻa i ka laulā o nā aniani a me nā waihoʻoluʻu e hoʻonui i ka lōʻihi o waho, ka paʻa ʻana o ka nani, ka paʻa ʻana o ke kala a me ka pale corrosion. Hoʻohana ʻia kēia mau huahana e like me ka hoʻopau ʻana i ka lole hoʻokahi i ka mahiʻai, lawn a me ka māla, mea hana, a me nā ʻoihana ea.

Hoʻohana maʻamau ka cathodic acrylic electrocoatings i nā noi kahi e makemake ʻia ai ka lōʻihi o UV a me ka pale corrosion ma nā substrates ferrous (steel). Hoʻohana ʻia nā acrylic cathodic i nā noi kahi e makemake ʻia ai nā kala māmā.

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana electrocoat i ʻehā mau ʻāpana ʻokoʻa:

• Hoʻomaʻamaʻa mua

• ka pahu E-coat a me nā mea hoʻohui

• Holoi ma hope

• Ka umu ho'ōla

Ma kahi kaʻina hana e-coat maʻamau, hoʻomaʻemaʻe mua ʻia nā ʻāpana a hoʻomaʻamaʻa mua ʻia me kahi uhi hoʻololi phosphate e hoʻomākaukau i ka ʻāpana no ka electrocoating. Hoʻokomo ʻia nā ʻāpana i loko o kahi ʻauʻau pena kahi e hoʻohana ʻia ai ke au pololei ma waena o nā ʻāpana a me kahi electrode "counter". Hoʻokomo ʻia ka pena e ke kahua uila i ka ʻāpana a waiho ʻia ma ka ʻāpana. Wehe ʻia nā ʻāpana mai ka ʻauʻau ʻauʻau, holoi ʻia e kiʻi hou i nā mea pena i hoʻopaʻa ʻole ʻia, a laila kālua ʻia e hoʻōla i ka pena.

Ma mua o ka pena kiʻiʻoniʻoni, loaʻa i ka hapa nui o nā ʻili metala ka hoʻomaʻamaʻa mua ʻana e pili ana i kahi uhi hoʻololi.

ʻO ke kaʻina hana hoʻomaʻamaʻa maʻamau no ka e-coat aia nā pae aʻe:

1) Hoʻomaʻemaʻe (hoʻokahi a ʻoi aku paha nā pae)

2) Holoi

3) Hoʻolima

4) ka uhi hoʻololi

5) Holoi

6) Ma hope o ka mālama ʻana

7) Holoi wai deionized.

Hiki ke hoʻokaʻawale ʻia nā kaʻina hana Phosphating i ʻelua ʻano: iron phosphate a me zinc phosphate. ʻO ka hao phosphate ke kaʻina hana i koho ʻia no nā noi kahi e ʻoi aku ai ka noʻonoʻo ʻana i nā kumukūʻai holoʻokoʻa i nā pono hana. No ka mea, ʻoi aku ka lahilahi o nā phosphates hao ma mua o ka zinc phosphates a aia wale nō ka ion metala o ka substrate e hana ʻia ana, hāʻawi lākou i ka hōʻemi ʻana i ka corrosion i hoʻohālikelike ʻia me kahi ʻōnaehana zinc phosphate. Eia nō naʻe, me ka piʻi ʻana o ka paʻa o ke kaiapuni e pili ana i nā metala kaumaha, hiki i kahi uhi hao phosphate i hui pū ʻia me ka hoʻomaʻamaʻa hope ʻana ke hāʻawi i kahi koho kūpono ʻoiai e hoʻokō mau ana i nā kikoʻī corrosion e pono ai. Ua lilo ʻo Zinc phosphates i mea lapaʻau prepaint makemake ʻia i ka ʻoihana hoʻopau metala, ʻoi loa me ka hoʻohana ʻana i nā ʻōnaehana pena electrocoat. ʻO ke kumu, hāʻawi lākou i ka pale ʻana i ka corrosion maikaʻi a me ka hoʻopili paʻi ʻana ma mua o ka hao phosphates ma lalo o nā kūlana koi.
