Epoxy Powder Coating
Intshayelelo yemveliso:
I-epoxy powder coating yenziwe nge-epoxy resin eneempawu ezahlukeneyo kunye ne-Chelsea yokunyanga i-agent. Ibonakala ngokugcina amandla, ungcoliseko oluphantsi kunye nokusebenza kakuhle. Ayinakuba yifilim kuphela, ukusebenza kakuhle kokwambathisa kuphezulu, kwaye ukusebenza komphezulu wokuchasana nomhlwa kulungile, amandla omatshini aphezulu.
Umgubo wokwaleka usetyenziswa ikakhulu kulwakhiwo, uhombiso, izixhobo zasekhaya, ifanitshala yentsimbi, izixhobo, uhola wendlela yokugada, iinxalenye zemoto, ukuqina kwezixhobo zemidlalo kunye namanye amashishini.
Intshayelelo ngokubanzi:
I-epoxy resin isetyenziswa njengeyona nto iphambili ekrwada. Inokumelana neekhemikhali ezigqwesileyo kunye neempawu zoomatshini. Kufanelekile ukugubungela iimveliso zetsimbi ezineemfuno eziphezulu kwi-corrosion resistance, ukugquma kombane kunye nokuguquguquka. Ngokuqhelekileyo akukhuthazwa ukuba ufake isicelo ngokuthe ngqo kumphezulu wazo zonke iintlobo zeemveliso zangaphandle.
Ubungakanani besicelo:
Peyinta umphezulu wesinyithi wamalungu emoto, izixhobo zendlu, ifenitshala yentsimbi, izibonelelo zeofisi kunye neendidi ezahlukeneyo zemibhobho.
Uthotho lweMveliso:
Ukubonelela ngomgangatho ophantsi kunye nobushushu obuphantsi bokugquma umgubo; Ingenziwa kwiimveliso ezinokukhanya okuphezulu (80% ngaphezulu), i-semi-light (50-80%), ukukhanya okukhanyayo (20-50%) kunye nokungakhanyisi (ngaphantsi kwe-20%). (Iglosi inokulawulwa ngokweemfuno zabasebenzisi).
Iimpawu ezibonakalayo:
Umxhuzulane okhethekileyo(g/cm3, 25℃): 1.4-1.7
Ukuhanjiswa kobungakanani besuntswana: 100% ngaphantsi kwe-100micron (Inokulungelelaniswa ngokweemfuno ezikhethekileyo zokugquma)
Iimeko zokwakha:
Unyango lwangaphambili: Unyango lwangaphambili olwahlukeneyo lusetyenziselwa ama-substrates ahlukeneyo (unyango lwe-phosphating, unyango lokuqhunyiswa kwesanti, unyango lokuchama, nceda uqhagamshelane nathi ngolwazi oluthe vetshe)
Ibhedi enolwelo, ukufunxa ivacuum, ukutyabeka ngerola, umpu wezandla okanye ozenzekelayo wombane kunye nezinye iindlela zingasetyenziselwa ukwakha.
Iimeko zokunyanga:
Uhlobo A: 200℃(iqondo lobushushu), 15 min (flat okanye flat)
Uhlobo B 180℃(ubushushu besixhobo sokusebenza), 15 min (ugqatso okanye isiqingatha seglosi)
Uhlobo C 140℃(iqondo lobushushu), 15 min (ugqatso)
Ukusebenza kokwaleka:
| Into yovavanyo | Umgangatho wokuhlola okanye indlela | Iimpawu zovavanyo | |
| A | B, C | ||
| ukumelana nefuthe | ISO 6272 | 40 kg.cm | 50 kg.cm |
| uvavanyo ikomityi | ISO 1520 | 5 mm | 8 mm |
| amandla okuncamathelisa (indlela yeletiyisi yomqolo) | ISO 2409 | 0 inqanaba | |

| 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 obuyi-60-80 microns.
2.Isalathiso sokusebenza sale ngubo ingentla inokuncipha kancinci ngokuncipha kweglosi.
Umndilili wokugubungela:
9-12 sq.m./kg; Ubukhulu befilimu i-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 zokugcina:
Icocekile, yomile, ingena umoya, kude nokukhanya, ubushushu begumbi bungaphantsi kwe 30℃, kwaye kufuneka igqunywe kwindawo yomlilo, kude nobushushu. Kwaye kufuneka igqume umthombo womlilo, zigcine kude nomthombo wobushushu. Ixesha elisebenzayo lokugcina iinyanga ezili-12 ukususela kumhla wokuvelisa. Kuphephe ukupakisha ngaphezulu kwe-4 umaleko.
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.
