I-Epoxy Polyester Powder Coating
Isingeniso Esijwayelekile:
I-Epoxy resin ne-polyester resin zisetshenziswa njengezinto zokusetshenziswa eziyinhloko, futhi zinezakhiwo zazo eziyingqayizivele, ukuze ifilimu ekhiqiziwe ibe nokuhlobisa okuhle kakhulu, izakhiwo zemishini kanye nokumelana nokugqwala okuqinile, okusetshenziselwa kakhulu ukumbozwa kwemikhiqizo yensimbi ehlukahlukene yasendlini.
Ububanzi besicelo: Ukuhlobisa nokumboza endaweni yensimbi yezinto zasendlini, ifenisha yensimbi, izinsiza zehhovisi, imishini ye-electromechanical, izinto zokuhlobisa zangaphakathi, izesekeli zemoto, amathoyizi ezingane, njll.
Uchungechunge Lomkhiqizo:
Uhlobo olujwayelekile kanye nezinga lokushisa eliphansi le-powder coating eliqinile
Ingenziwa imikhiqizo enokukhanya okuphezulu (80% ngaphezulu), ukukhanya okuncane (50-80%), ukukhanya okuyisicaba (20-50%) nokungakhanyi (ngaphansi kuka-20%). Ngokwezidingo zomsebenzisi zokulawula isicwebezelisi.
Izakhiwo Zomzimba:
Amandla adonsela phansi athile(g/cm3, 25℃): 1.4-1.7
Ukusatshalaliswa kosayizi wezinhlayiya: 100% ngaphansi kwe-micron eyi-100 (Kungashintshwa ngokuya ngezidingo ezikhethekile zokumboza)
Izimo zokwakha:
Ukwelashwa ngaphambi kwesikhathi: Izindlela zokwelashwa ezihlukene zisetshenziselwa ama-substrates ahlukene (ukwelashwa kwe-phosphating, ukwelashwa kwe-sandblasting, ukwelashwa kokuchama okudutshulwa, sicela usithinte ukuze uthole imininingwane eyengeziwe)
Imodi yokwelapha: ingelapheka nge-infrared kagesi, i-infrared yegesi, indlela yokomisa yokushisa, ihhavini nezinye izindlela
Izimo Zokwelapha:
I-180 ℃ ejwayelekile (izinga lokushisa lokusebenzela), imizuzu eyi-15
Izinga lokushisa eliphansi elilungisiwe uhlobo lwe-160 ℃(i-workpiece lokushisa), i-15 min
Ukusebenza kwe-coating:
| Into yokuhlola | Indinganiso yokuhlola noma indlela | Izinkomba zokuhlola |
| ukumelana nomthelela | ISO 6272 | 50 kg.cm |
| ukuhlolwa kwenkomishi | ISO 1520 | 8 mm |
| i-adhesive force (indlela ye-lattice yomugqa) | ISO 2409 | 0 izinga |
| ukugoba | ISO 1519 | 2 mm |
| ubulukhuni bepensela | I-ASTM D3363 | 1H-2H |
| ukuhlolwa kwesifutho sikasawoti | ISO 9227 | > amahora angu-500 |
| ukuhlolwa okushisayo nokunomswakama | ISO 6270 | > 1000 amahora |
| ukumelana nokushisa | 100℃X24 amahora (amhlophe) | ukugcinwa kokukhanya okuhle kakhulu, umehluko wombala≤ 0.3-0.4 |
Amanothi:
1.Ukuhlola okungenhla kusebenzise amapuleti ensimbi awugqinsi agoqelwe ngokubanda angu-0.8mm anogqinsi lwama-microns angu-30-40 ngemva kokwelashwa kwangaphambili okujwayelekile.
2.Inkomba yokusebenza ye-coating engenhla ingase yehle kancane ngokuncipha kwesicwebezelisi.
Ukufakwa okumaphakathi:
9-14 sq.m./kg; ukujiya kwefilimu ama-microns angama-60 (abalwe ngesilinganiso sokusebenzisa impuphu engu-100%)
Ukupakisha nezokuthutha:
amabhokisi ahlanganiswe nezikhwama ze-polyethylene, isisindo senetha singama-20kg; Izinto ezingezona eziyingozi zingathuthwa ngezindlela ezihlukahlukene, kodwa kuphela ukugwema ukukhanya kwelanga, umswakama nokushisa, nokugwema ukuthintana nezinto zamakhemikhali.
Izidingo zesitoreji: Hlanza, yomile, ingene umoya, kude nokukhanya, izinga lokushisa legumbi elingaphansi kuka-30℃, futhi kufanele ivalwe emthonjeni womlilo, kude nomthombo wokushisa.
Amanothi:
Zonke izimpushana ziyacasula ohlelweni lokuphefumula, ngakho gwema ukuhogela impushana nesitimu ekwelapheni. Zama ukugwema ukuthintana okuqondile phakathi kwesikhumba kanye ne-powder coating. Geza isikhumba ngamanzi nensipho uma kudingeka. Uma uthintana namehlo, geza isikhumba ngokushesha ngamanzi ahlanzekile futhi ufune usizo lwezokwelapha ngokushesha. Ingqimba yothuli kanye nokufakwa kwezinhlayiya zempushana kufanele kugwenywe endaweni engaphezulu nasekhoneni elifile. Izinhlayiya ezincane ze-organic zizovutha futhi zidale ukuqhuma ngaphansi kukagesi omile. Zonke izinto ezisetshenziswayo kufanele zimiswe phansi, futhi izisebenzi zokwakha kufanele zigqoke izicathulo ezimelene ne-static ukuze kugcinwe inhlabathi ukuze kuvinjelwe ugesi ongashintshi.
