Panja Mbiri Yomanga Panja Powder Spray Paint Coating Line

Aluminiyamu yomanga mbiri electrostatic ufa kupopera mbewu mankhwalawa makamaka utenga mkulu-voltage electrostatic njira, chifukwa mbiri nyumba zimagwiritsa ntchito panja, ufa ambiri ntchito thermosetting poliyesitala ufa ❖ kuyanika ndi ntchito bwino mabuku.

Mfundo yaikulu ndi yakuti electrode pa thupi lamfuti ndi jenereta yothamanga kwambiri yolumikizidwa kuti ipange malo okwera kwambiri a electrostatic, kotero kuti mpweya wozungulira mfuti corona ionization, chifukwa cha gawo la magetsi a corona.

Pamene ufa ndi sprayed kuchokera mfuti, ndi ufa particles kugunda ndi ionized mpweya particles kupanga zoipa mlandu particles, amene kenako anatumiza workpiece pansi ndi airflow kuti adsorbed. Kupaka kwa ufa kumachiritsidwa ndi kuphika, motero kukwaniritsa cholinga cha kupaka.

Cholinga chachikulu cha pretreatment pamwamba ndi kuchotsa mafuta, pang'ono extrusion zizindikiro ndi filimu okusayidi zachilengedwe padziko mbiri aluminiyamu kuti akwaniritse lathyathyathya mbiri pamwamba, ndiyeno kupeza 0.5-2μm kutembenuka filimu kudzera makutidwe ndi okosijeni mankhwala.

Mbiri ayenera degreased bwinobwino mu pretreatment ndondomeko, ngati degreasing si woyera, zidzachititsa chosakwanira kutembenuka filimu, osauka adhesion wa ufa wosanjikiza, pamwamba sachedwa zilema monga concave cavities, pinholes, etc., ndi madzi , mpweya ndi ayoni zidzalowa mkati mwa zokutira kuti zilowe pamwamba pazitsulo, zomwe zimapangitsa kuti gawo lapansi liwonongeke.

Degreasing, neutralization, kusintha kuyenera kuchitika pambuyo pa kutsuka bwino kwa madzi, kawirikawiri pambuyo pa ndondomeko iliyonse iyenera kutsukidwa kawiri, pambuyo pa kusinthika kwa madzi osamba ndi bwino kugwiritsa ntchito madzi oyera, kupyolera mu kutsuka kwa madzi kuchotsa zotsalira za pamwamba, kuti musamawononge. kupangitsa kutsitsi ❖ kuyanika matuza, kudetsa, ndi mawonekedwe ndi zitsulo kuwonongedwa, imathandizira dzimbiri zitsulo pansi ❖ kuyanika.

Pambuyo pokonzekera, mbiriyo iyenera kuumitsidwa nthawi yomweyo, kuti pamwamba pasamasunge chinyezi, ngati mawonekedwe a pamwamba amasunga chinyezi mu njira yopaka ufa A, chophimbacho chidzatulutsa thovu.

Onani kuti kuyanika kutentha sayenera upambana 130 ℃, kutentha ndi mkulu kwambiri adzapanga kutembenuka filimu kwambiri imfa ya crystalline madzi ndi kusandulika, kukhala lotayirira ndi kupanga ❖ kuyanika adhesion.

Mbiri atapachikidwa mu unyolo conveyor mu ufa ❖ kuyanika booth, zoipa mlandu ufa ❖ kuyanika particles m'munda electrostatic, mothandizidwa ndi wothinikizidwa mpweya pagalimoto adsorption padziko mbiri, ufa wogawana TACHIMATA pamwamba pa mbiri, ndipo posachedwapa. fikani pamiyezo yaukadaulo yotchulidwa pazofunikira za makulidwe a kanema.

Pofuna kuonetsetsa khalidwe ❖ kuyanika mbiri, ndi kupopera ufa ndondomeko ayenera kuganizira kulamulira makulidwe a ufa wosanjikiza. Ufa wosanjikiza ndi woonda kwambiri, wosakwana 45μm sungathe kuphimba tinthu tating'onoting'ono ta ufa, kotero kuti tinthu tating'onoting'ono tiwonjezeke, zomwe zimapangitsa kuti ❖ kuyanika kusakhale kofanana. Ufa wosanjikiza ndi wandiweyani kwambiri, womwe umakhudza kusungunuka kwa ufa; kupaka kumatulutsa zizindikiro zotuluka ndi peel lalanje. Kuonjezera apo, makulidwe a filimu amakhudzanso gloss ya zokutira, mphamvu zowonongeka, ndi kukana kwa nyengo ndi zina zotero.

Pambuyo kupopera mbewu mankhwalawa, mbiriyo imalowa mu uvuni wochiritsira, ndipo ufa womwe umayikidwa pamwamba pa mbiriyo umasungunuka ndi kutentha ndi kuphika, ndipo mpweya womwe uli pamphepete mwa ufa umatulutsidwa, ndipo umasungunuka pang'onopang'ono, gelatinized ndi kuchiritsidwa. mufilimu.

Kuchiritsa ndondomeko ndi njira yofunika kwambiri ❖ kuyanika ufa, kumanga mbiri aluminiyamu ntchito thermosetting polyester ufa ❖ kuyanika, chofunika kuchiritsa kutentha 180 ℃, nthawi 20min.

Lumikizanani nafe kuti musinthe mzere wanu!
