Epoxy Powder Coating
Chidziwitso cha malonda:
Epoxy powder yokutira imapangidwa kuchokera ku epoxy resin yokhala ndi katundu wosiyanasiyana ndi wothandizira ku Chelsea. Amadziwika ndi kupulumutsa mphamvu, kuwononga pang'ono komanso kuchita bwino kwambiri. Sikuti akhoza kukhala filimu, ❖ kuyanika dzuwa ndi mkulu, ndi pamwamba ❖ kuyanika odana dzimbiri ntchito zabwino, mkulu mawotchi mphamvu.
The ❖ kuyanika ufa makamaka ntchito yomanga, kukongoletsa, zipangizo zapakhomo, mipando zitsulo, zida, msewu guardrail, mbali galimoto, olimba masewera zida ❖ kuyanika ndi mafakitale ena.
Mau oyamba:
Epoxy resin imagwiritsidwa ntchito ngati zopangira zazikulu. Iwo ali kwambiri kukana mankhwala ndi katundu makina. Ndizoyenera kupaka zitsulo zokhala ndi zofunikira kwambiri pa kukana kwa dzimbiri, kutsekemera kwamagetsi ndi kusinthasintha. Nthawi zambiri osavomerezeka kugwiritsa ntchito mwachindunji pamwamba pa mitundu yonse ya zinthu zakunja.
Kuchuluka kwa ntchito:
Pentani zitsulo pamwamba pa mbali za galimoto, zipangizo zapakhomo, mipando yachitsulo, maofesi a maofesi ndi mitundu yosiyanasiyana ya mapaipi.
Mndandanda wazinthu:
Kupereka muyezo 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%). (Kuwala kumatha kuyendetsedwa malinga ndi zomwe ogwiritsa ntchito amafuna).
Zathupi:
Kukoka kwapadera (g/cm3, 25 ℃): 1.4-1.7
Kugawa kwa tinthu ting'onoting'ono: 100% zosakwana 100micron (Itha kusinthidwa malinga ndi zofunikira za ❖ kuyanika)
Zomangamanga:
Prepreatment: Mitundu yosiyanasiyana ya pretreatment imagwiritsidwa ntchito popanga magawo osiyanasiyana (mankhwala a phosphating, kuwotcha mchenga, kuwomberedwa, chonde titumizireni kuti mumve zambiri)
Bedi lamadzimadzi, kuyamwa vacuum, zokutira zogudubuza, mfuti yamanja kapena automatic electrostatic ndi njira zina zitha kugwiritsidwa ntchito pomanga.
Zochizira:
Mtundu A: 200 ℃ (kutentha kwa workpiece), 15 min (yophwatsuka kapena yosalala)
Type B 180 ℃(kutentha kwa workpiece), 15 min (kuwunikira kapena theka-gloss)
Type C 140 ℃ (kutentha kwa workpiece), 15 min (zowunikira)
Kuchita kwa zokutira:
| Chinthu choyesera | Kuyendera muyezo kapena njira | Zizindikiro zoyesa | |

Ndemanga:
1.Mayeso omwe ali pamwambawa adagwiritsa ntchito mbale zachitsulo zoziziritsa kuzizira za 0.8mm zokhala ndi makulidwe a 60-80 microns.
2. Mndandanda wa ntchito za zokutira pamwambapa ukhoza kuchepa pang'ono ndi kuchepa kwa gloss.
Kufalikira kwapakati:
9-12 sq.m./kg; filimu makulidwe ma microns 60 (owerengedwa ndi 100% ufa ❖ kuyanika magwiritsidwe 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.
Zofunikira 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. Ndipo ayenera kutsekereza gwero la moto, khalani kutali ndi gwero la kutentha. Nthawi yosungira bwino ndi miyezi 12 kuyambira tsiku lopangidwa. Pewani kusanjikiza magawo opitilira 4.
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.
