I-Epoxy Powder Coating
Isingeniso somkhiqizo:
I-epoxy powder coating yenziwe nge-epoxy resin enezakhiwo ezahlukene kanye ne-Chelsea elaphayo. Ibonakala ngokonga amandla, ukungcola okuphansi nokusebenza kahle okuphezulu. Akukhona nje kuphela ukuthi kungaba ifilimu, ukusebenza kahle kwe-coating kuphezulu, futhi ukusebenza kwe-surface anti-corrosion kusebenza kahle, amandla aphezulu emishini.
I-powder coating isetshenziswa kakhulu ekwakheni, ekuhlobiseni, ezintweni zasendlini, ifenisha yensimbi, amathuluzi, umgwaqo onguthelawayeka, izingxenye zezimoto, ukuqina kwemishini yezemidlalo nezinye izimboni.
Isingeniso esijwayelekile:
I-epoxy resin isetshenziswa njengento eyinhloko eluhlaza. Inokumelana okuhle kakhulu kwamakhemikhali kanye nezakhiwo zemishini. Ifanele ukumboza imikhiqizo yensimbi enezidingo eziphezulu ekuphikiseni ukugqwala, ukufakwa kukagesi nokuguquguquka. Ngokuvamile akunconywa ukusebenzisa ngokuqondile phezu kwazo zonke izinhlobo zemikhiqizo yangaphandle.
Ububanzi besicelo:
Penda ingaphezulu lensimbi lezingxenye zemoto, izinto zikagesi zasendlini, ifenisha yensimbi, izinsiza zamahhovisi kanye nezinhlobo ezahlukene zamapayipi.
Uchungechunge lomkhiqizo:
Ukuhlinzeka ngezinga lokushisa eliphansi eliqinile le-powder enamathela; Ingenziwa imikhiqizo enokukhanya okuphezulu (80% ngaphezulu), ukukhanya okuncane (50-80%), ukukhanya okuyisicaba (20-50%) nokungakhanyi (ngaphansi kuka-20%). (Isicwebezelisi singalawulwa ngokwezidingo zabasebenzisi).
Izinto ezibonakalayo:
Amandla adonsela phansi athile(g/cm3, 25℃): 1.4-1.7
Ukusatshalaliswa kosayizi wezinhlayiya: 100% ngaphansi kuka-100micron (Kungashintshwa ngokuya ngezidingo ezikhethekile zokumboza)
Izimo zokwakha:
Ukwelashwa ngaphambi kwesikhathi: Ukwelashwa kwangaphambili okuhlukile kusetshenziselwa ama-substrates ahlukene (ukwelashwa kwe-phosphating, ukuqhunyiswa kwesihlabathi, ukwelashwa kokuchama, sicela usithinte ukuze uthole imininingwane eyengeziwe)
Umbhede owuketshezi, ukumuncwa kwevacuum, i-roller coating, isibhamu esisetshenziswa ngesandla noma esizenzakalelayo kanye nezinye izindlela zingasetshenziselwa ukwakha.
Izimo zokuphulukisa:
Uhlobo A: 200℃(izinga lokushisa lomshini wokusebenza), 15 min (flat noma flat)
Thayipha B 180℃(ithempelesha yomshini wokusebenza), imizuzu eyi-15 (igqamisa noma i-semi-gloss)
Thayipha u-C 140℃(izinga lokushisa lomshini wokusebenza), imizuzu eyi-15 (gqamisa)
Ukusebenza kwe-coating:

Amanothi:
1.Ukuhlola okungenhla kusebenzise amapuleti ensimbi awugqinsi angu-0.8mm anogqinsi lwama-microns angu-60-80.
2.Inkomba yokusebenza ye-coating engenhla ingase yehle kancane ngokuncipha kwesicwebezelisi.
Ukufakwa okumaphakathi:
9-12 sq.m./kg; ukujiya kwefilimu ama-microns angama-60 (abalwe ngesilinganiso sokusebenzisa i-powder 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:
Ihlanzekile, yomile, ingena umoya, kude nokukhanya, izinga lokushisa legumbi elingaphansi kuka-30 ℃, futhi kufanele lifakwe endaweni yomlilo, kude nomthombo wokushisa. Futhi kufanele insulate umthombo umlilo, gcina kude umthombo ukushisa. Isikhathi sokugcina esisebenzayo yizinyanga eziyi-12 kusukela ngosuku lokukhiqiza. Gwema ukunqwabelanisa izendlalelo ezingaphezu kwezi-4.
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.
