Polyurethane Powder Coating
Intshayelelo ngokubanzi:
Iingubo zomgubo ezenziwe nge-hydroxyl polyester resin, ezineempawu zekhemikhali ezigqwesileyo, kunye nokuhombisa okuhle kakhulu, ukulinganisa, ukuxhathisa imichiza, ukumelana nemozulu kunye nokuxhathisa okuqinileyo kwe-oyile. Ifanelekile imbonakalo yentsimbi yokugquma ibhayisekile, imoto, isithuthuthu, umatshini wokugcwalisa i-refueling kunye noomatshini bezolimo abanemfuno ephezulu yokuchasa iikhemikhali kunye nokumelana neoyile.
Uluhlu lweMveliso:
Ukubonelela ngamagqabantshintshi (80% ngasentla), isemi-light (50-80%), iglasi engenanto (20-50%) kwaye akukho ukukhanya (20% ngezantsi) iimveliso okanye kwiimfuno
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 lwesubstrates ezahlukeneyo (unyango lwephosphating, unyango lokutshiza ngengxolo, unyango lokuchama oludutyulweyo)
Imo yokunyanga: ukwakhiwa kompu omileyo owenziwe ngesandla okanye ozenzekelayo
Iimeko zokunyanga: 200 ℃ (ubushushu bokusebenza), imizuzu eyi-10
Ukusebenza kokwaleka:
| Into yovavanyo | Umgangatho wokuhlola okanye indlela | Iimpawu zovavanyo |
| ukumelana nefuthe | ISO 6272 | 50kg.cm |
| uvavanyo ikomityi | ISO 1520 | 8mm |
| amandla okuncamathelisa (indlela yeletiyisi yomqolo) | ISO 2409 | 0 inqanaba |
| ukugoba | ISO 1519 | 2mm |
| ukuqina kwepensile | I-ASTM D3363 | 1H-2H |
| uvavanyo lokutshiza ityuwa | ISO 7253 | > iiyure ezingama-500 |
| uvavanyo olushushu kwaye lufumile | ISO 6270 | > 1000 iiyure |
| ukumelana nobushushu | 150℃/24 iiyure (ezimhlophe) | ugcino olubalaseleyo lokukhanya, umahluko wombala≤0.3-0.4 |
Amanqaku:
1.Olu vavanyo lungentla lusebenzise iipleyiti zentsimbi ezingqindilili eziyi-0.8mm ezinobukhulu obuyi-50-70 microns.
2.Isalathiso sokusebenza sale ngubo ingentla inokutshintsha ngokutshintsha kombala kunye neglosi.
Umndilili wokugubungela:
9-11 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:
Icocekile, yomile, ingena umoya, kude nokukhanya, ubushushu begumbi bungaphantsi kwe-30 ℃, kwaye kufuneka igqunywe kumthombo womlilo, kude nomthombo wobushushu.Ixesha logcino olusebenzayo ziinyanga ezili-12 ukusuka kumhla wemveliso. 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.
