Epoxy Polyester Powder Coating
Intshayelelo ngokubanzi:
I-epoxy resin kunye ne-polyester resin zisetyenziswa njengezona zixhobo ziphambili, kwaye zineempawu zazo ezizodwa, ukuze ifilimu eveliswayo ibe neyona ndlela ibalaseleyo yokuhombisa, iipropathi zoomatshini kunye nokumelana nomhlwa okunamandla, okusetyenziswa ngokubanzi ekugqumeni kweemveliso zentsimbi zangaphakathi.
Ubungakanani besicelo: Ukuhlobisa kunye nokugquma kwindawo yentsimbi yezixhobo zendlu, ifenitshala yentsimbi, izixhobo zeofisi, izixhobo ze-electromechanical, izinto zokuhombisa zangaphakathi, izixhobo zemoto, amathoyizi abantwana, njl.
Uluhlu lweMveliso:
Uhlobo olusemgangathweni kunye nobushushu obuphantsi obuqinisiweyo bokugquma umgubo
Ingenziwa kwiimveliso ezinokukhanya okuphezulu (80% ngaphezulu), i-semi-light (50-80%), ukukhanya okukhanyayo (20-50%) kunye nokungakhanyisi (ngaphantsi kwe-20%). Ngokweemfuno zomsebenzisi ukulawula iglosi.
Iinkcazelo Ngeempawu:
Umxhuzulane okhethekileyo(g/cm3, 25℃): 1.4-1.7
Ukuhanjiswa kobungakanani besuntswana: 100% ngaphantsi kwe-100 micron (Inokulungelelaniswa ngokweemfuno ezikhethekileyo zokugquma)
Iimeko zokwakha:
Unyango lwangaphambili: Unyango lwangaphambili olwahlukeneyo lusetyenziselwa ama-substrates ahlukeneyo (unyango lwe-phosphating, unyango lwe-sandblasting, unyango lokuchama, nceda uqhagamshelane nathi ngolwazi oluthe vetshe)
Imowudi yokunyanga: inokunyangwa nge-infrared yombane, i-infrared yegesi, indlela yokomisa ubushushu, i-oveni kunye nezinye iindlela.
Iimeko zokunyanga:
Umgangatho we-180 ℃ (ubushushu bomsebenzi), i-15 min
Ubushushu obuphantsi obumiselweyo uhlobo lwe-160 ℃(ubushushu besixhobo sokusebenza), i-15 min
Ukusebenza kokwaleka:
| Into yovavanyo | Umgangatho wokuhlola okanye indlela | Iimpawu zovavanyo |
| ukumelana nefuthe | ISO 6272 | 50 kg.cm |
| uvavanyo ikomityi | ISO 1520 | 8 mm |
| amandla okuncamathelisa (indlela yeletiyisi yomqolo) | ISO 2409 | 0 inqanaba |
| ukugoba | ISO 1519 | 2 mm |
| ukuqina kwepensile | I-ASTM D3363 | 1H-2H |
| uvavanyo lokutshiza ityuwa | ISO 9227 | > iiyure ezingama-500 |
| uvavanyo olushushu kwaye lufumile | ISO 6270 | > 1000 iiyure |
| ukumelana nobushushu | 100℃X24 iiyure (ezimhlophe) | ugcino olubalaseleyo lokukhanya, umahluko wombala≤ 0.3-0.4 |
Amanqaku:
1.Olu vavanyo lungentla lusebenzise iipleyiti zentsimbi eziqengqelekayo eziyi-0.8mm ezinobukhulu obungama-30-40 eemicrons emva konyango lwangaphambili.
2.Isalathiso sokusebenza sale ngubo ingentla inokuncipha kancinci ngokuncipha kweglosi.
Umndilili wokugubungela:
9-14 sq.m./kg; Ubukhulu befilimu buyi-60 microns (ibalwe nge-100% yezinga lokusetyenziswa komgubo)
Ukupakisha kunye nokuthutha:
iikhathoni zifakwe iingxowa ze-polyethylene, ubunzima bobunzima bungama-20kg; Izinto ezingekho yingozi zinokuthuthwa ngeendlela ezahlukeneyo, kodwa kuphela ukuphepha ukukhanya kwelanga, umswakama kunye nobushushu, kwaye ugweme ukudibanisa nezinto zekhemikhali.
Iimfuno zogcino: Coca, yomile, ingene umoya, kude nokukhanya, ubushushu begumbi bungaphantsi kwe-30℃, kwaye kufuneka igqunywe kwindawo yomlilo, kude nobushushu.
Amanqaku:
Zonke ii powders ziyayicaphukisa inkqubo yokuphefumla, ngoko ke kunqanda ukuphefumla umgubo kunye nomphunga ekunyangeni. Zama ukuphepha ukudibanisa ngokuthe ngqo phakathi kwesikhumba kunye nomgubo wokugquma. Hlamba ulusu ngamanzi kunye nesepha xa kufuneka ukudibana. Ukuba ukudibana kwamehlo kwenzeka, hlamba ulusu ngokukhawuleza ngamanzi acocekileyo kwaye ufune unyango ngokukhawuleza. Umaleko wothuli kunye ne-powder particle deposition kufuneka igwenywe kumphezulu kunye nekona efileyo. Amasuntswana amancinci aphilayo aya kuvutha kwaye abangele ukuqhuma phantsi kombane omileyo. Zonke izixhobo kufuneka zibekwe phantsi, kwaye abasebenzi bokwakha kufuneka banxibe izihlangu ezichasene ne-static ukugcina umhlaba ukuthintela umbane ongatshintshiyo.
