Epoxy Polyester Powder Coating
Mau Oyamba:
Utomoni wa epoxy ndi utomoni wa poliyesitala amagwiritsidwa ntchito ngati zida zazikulu zopangira, ndipo amakhala ndi mawonekedwe awoawo, kotero kuti filimu yopangidwayo imakhala ndi zokongoletsera zabwino kwambiri, zamakina komanso kukana kwamphamvu kwa dzimbiri, zomwe zimagwiritsidwa ntchito kwambiri pakupaka zitsulo zosiyanasiyana zamkati.
Kuchuluka kwa ntchito: Kukongoletsa ndi zokutira pazitsulo zazitsulo zapakhomo, mipando yachitsulo, maofesi aofesi, zida za electromechanical, zokongoletsera zamkati, zipangizo zamagalimoto, zoseweretsa za ana, ndi zina zotero.
Mndandanda wazinthu:
Standard mtundu ndi otsika kutentha solidified ufa ❖ kuyanika
Itha kupangidwa kukhala zinthu zokhala ndi kuwala kwakukulu (80% pamwambapa), kuwala kwa theka (50-80%), kuwala kosalekeza (20-50%) komanso osawala (osakwana 20%).Malinga ndi zomwe wogwiritsa ntchito amafuna kuti azilamulira gloss.
Katundu Wathupi:
Kukoka kwapadera (g/cm3, 25 ℃): 1.4-1.7
Kugawa kwa tinthu ting'onoting'ono: 100% zosakwana 100 micron (Itha kusinthidwa malinga ndi zofunikira za ❖ kuyanika)
Zomangamanga:
Pretreatment: Mitundu yosiyanasiyana ya pretreatment imagwiritsidwa ntchito pazinthu zosiyanasiyana (phosphating treatment, sandblasting treatment, shot peening treatment, chonde titumizireni kuti mudziwe zambiri)
Kuchiritsa mode: itha kuchiritsidwa ndi infuraredi yamagetsi, infuraredi yamagetsi, njira yowumitsa kutentha, uvuni ndi njira zina.
Kuchiritsa Mikhalidwe:
Standard 180 ℃ (kutentha kwa workpiece), 15 min
Kutentha kochepa kokhazikika 160 ℃ (kutentha kwa workpiece), 15 min
Kuchita kwa zokutira:
| Chinthu choyesera | Kuyendera muyezo kapena njira | Zizindikiro zoyesa |
| kukana mphamvu | Mtengo wa ISO 6272 | 50 kg.cm |
| test test | ISO 1520 | 8 mm |
| zomatira mphamvu (njira ya mzere lattice) | ISO 2409 | 0 mlingo |
| kupinda | ISO 1519 | 2 mm |
| kulimba kwa pensulo | Chithunzi cha ASTM D3363 | 1H-2H |
| mayeso opopera mchere | ISO 9227 | > 500 maola |
| kuyesa kotentha ndi chinyezi | ISO 6270 | > 1000 maola |
| kukana kutentha | 100 ℃X24 maola (woyera) | kusungirako bwino kwambiri, kusiyana kwamitundu≤ 0.3-0.4 |
Ndemanga:
1.Mayeso omwe ali pamwambawa adagwiritsa ntchito mbale zachitsulo zoziziritsa kuzizira za 0.8mm zokhala ndi makulidwe a ma 30-40 ma microns mutatha kuwongolera.
2. Mndandanda wa ntchito za zokutira pamwambapa ukhoza kuchepa pang'ono ndi kuchepa kwa gloss.
Kufalikira kwapakati:
9-14 sq.m./kg;filimu makulidwe 60 microns (owerengeka ndi 100% ❖ kuyanika magwiritsidwe ntchito mlingo)
Kupakira ndi mayendedwe:
makatoni ali ndi matumba a polyethylene, kulemera kwa ukonde ndi 20kg;Zida zosakhala zoopsa zimatha kunyamulidwa m'njira zosiyanasiyana, koma kupeŵa kuwala kwa dzuwa, chinyezi ndi kutentha, komanso kupewa kukhudzana ndi mankhwala.
Zofunika posungira: Zoyera, zowuma, zokhala ndi mpweya wabwino, kutali ndi kuwala, kutentha kwa chipinda pansi pa 30 ℃, ndipo ziyenera kutetezedwa ku gwero lamoto, kutali ndi gwero la kutentha.
Ndemanga:
Ufa wonse umakwiyitsa dongosolo la kupuma, choncho pewani kutulutsa ufa ndi nthunzi kuti musachiritse.Yesetsani kupewa kukhudzana mwachindunji pakati pa khungu ndi kupaka ufa.Sambani khungu ndi madzi ndi sopo pamene kukhudzana kuli kofunikira.Ngati muyang'ana m'maso, sambani khungu nthawi yomweyo ndi madzi aukhondo ndipo pitani kuchipatala mwamsanga.Fumbi wosanjikiza ndi ufa tinthu mafunsidwe ayenera kupewa padziko ndi akufa ngodya.Tizilombo tating'onoting'ono timene timatulutsa timayaka ndi kuyambitsa kuphulika kwa magetsi osasunthika.Zida zonse ziyenera kukhala pansi, ndipo ogwira ntchito yomanga ayenera kuvala nsapato zoletsa static kuti pansi kuti ateteze magetsi osasunthika.
