I-Pretreatment E-coat Painting System E-coat Line

I-Electrocoating yinkqubo apho amasuntswana ahlawuliswa ngombane afakwa ngaphandle kokumiswa kwamanzi ukuze agqume indawo eqhubayo. Ngethuba lenkqubo ye-electrocoat, ipeyinti isetyenziswe kwinxalenye ethile kwifilimu ethile, elawulwa ngumlinganiselo wombane osetyenzisiweyo. I-deposition i-self-limiting kwaye iyancipha njengoko i-coating esetyenzisiweyo ikhusela indawo yombane. Izinto eziqinileyo ze-Electrocoat ekuqaleni zidiphozithi kwiindawo ezikufutshane ne-electrode yekhawuntari kwaye, njengoko ezi ndawo zigqunyelelwa ngoku, izinto eziqinileyo zinyanzelwa kwiindawo ezikhuselweyo zentsimbi ezikhuselweyo ukuze zibonelele ngokugqibeleleyo. Le nto yaziwa njengamandla okuphosa kwaye iyinkalo ebalulekileyo yenkqubo ye-e-coating.

Inkcazo

Cathodic epoxy electro-coatingluphawu lokumelana nomhlwa. Isetyenziswa kakhulu kwimizi-mveliso yeemoto kunye neyeemoto, ibonelela ngokutshizwa kwetyuwa ephezulu, ukufuma kunye nokumelana nokugqwala kwe-cyclic. Nangona kunjalo, itekhnoloji ye-cathodic epoxy ngokubanzi ifuna i-topcoat ukuba ikhuselwe ekukhanyeni kwelanga. Iingubo zohlobo lwe-epoxy ezinevumba elimnandi ziqhelene kakhulu ne-chalk kunye nokuthotywa kwezinto ze-UV zokukhanya kwelanga.

Cathodic acrylic electro-coatingifumaneka kuluhlu olubanzi lweglosi kunye nemibala yokwandisa ukuqina kwangaphandle, ukugcinwa kwegloss, ukugcinwa kombala kunye nokukhuselwa kwe-corrosion. Ezi mveliso zisetyenziselwa ukugqiba idyasi enye kwezolimo, ingca kunye negadi, izixhobo zombane, kunye nemizi-mveliso yokupholisa umoya.

I-Cathodic acrylic electrocoatings idla ngokusetyenziswa kwizicelo apho ukuqina kwe-UV kunye nokukhuselwa komhlwa kwi-ferrous substrates (intsimbi) ifunwayo. I-cathodic acrylics nayo isetyenziswa kwizicelo apho imibala ekhanyayo ifunwayo.

Umboniso weMveliso

Amanyathelo amane eNkqubo ye-Electrocoating

Inkqubo ye-electrocoat inokwahlulwa ibe ngamacandelo amane ahlukeneyo:

• Unyango lwangaphambili

• Itanki ye-e-coat kunye nezixhobo ezincedisayo

• Emva kokuhlamba

• I-oveni yokucoca

Kwinkqubo ye-e-coat eqhelekileyo, iinxalenye ziqale zicocwe kwaye zifakwe ngaphambili nge-phosphate conversion coating ukuze kulungiswe inxalenye ye-electrocoating. Amacandelo ke afakwe kwibhafu yepeyinti apho i-current ngqo isetyenziswe phakathi kwamacandelo kunye ne-electrode "counter". Ipeyinti itsalwa yintsimi yombane kwinxalenye kwaye ifakwe kwinxalenye. Amalungu asuswa kwindawo yokuhlambela, ahlanjululwe ukuze abuyisele i-solids yepeyinti engafakwanga, kwaye abhakwe ukunyanga ipeyinti.

Amanyathelo asixhenxe oNyango lwangaphambili

Ngaphambi kokusetyenziswa kwefilimu yepeyinti, iindawo ezininzi zetsimbi zifumana unyango lwangaphambili oluhlala lubandakanya ukuguqulwa kokuguqulwa.

Inkqubo eqhelekileyo yonyango lwangaphambili lwe-e-coat inala manyathelo alandelayo:

1) Ukucoca (inqanaba elinye okanye ngaphezulu)

2) Ukuhlamba

3) Ukulungelelanisa

4) Ukuguqulwa kokuguqulwa

5) Ukuhlamba

6) Emva konyango

7) Ukuhlanjululwa kwamanzi okuhlanjululwayo.

Iinkqubo ze-phosphate zinokwahlulwa zibe ziintlobo ezimbini: i-iron phosphate kunye ne-zinc phosphate. I-iron phosphate ibe yinkqubo ekhethwayo kwizicelo apho uqwalaselo lweendleko lulonke lungaphezu kweemfuno zokusebenza. Ekubeni i-iron phosphates i-coatings encinci kune-zinc phosphates kwaye iqulethe i-ion yensimbi ye-substrate ecutshungulwayo, ibonelela ngokunciphisa ukuxhathisa ukubola xa kuthelekiswa nenkqubo ye-zinc phosphate. Nangona kunjalo, ngezithintelo zokusingqongileyo ziya ziqina ngakumbi ngokubhekiselele kwisinyithi esinzima, i-iron phosphate yokwaleka edityaniswa nonyango olucokisekileyo lwesithuba inokubonelela ngenye indlela esebenzayo ngelixa ihlangabezana neenkcukacha zomhlwa. I-Zinc phosphates iye yaba yonyango olukhethiweyo lwe-prepaint kwishishini lokugqiba isinyithi, ngakumbi ngokusetyenziswa kweenkqubo zepeyinti ye-electrocoat. Isizathu sesokuba babonelela ngokumelana nokugqwala okungcono kunye nokuncamathela kwepeyinti kune-iron phosphates phantsi kweemeko ezinzima kakhulu.
