I-Powder Coating for Outdoor Building Decoration
Isingeniso Esijwayelekile:
Izembatho zempushana ezenziwe ngama-carboxylic polyester resins zivame ukubizwa ngokuthi izimbotshana zempushana ezingamelana nesimo sezulu. Isetshenziswa kakhulu ezikhungweni zangaphandle zesikhumulo sezindiza, umgoqo womgwaqo, idivayisi yokuhlukanisa abantu ngabanye, izinsiza zobunjiniyela bakamasipala, ibhokisi lokukhanya, isiphephetha-moya sangaphandle, ukuqina kwangaphandle nezinto zokungcebeleka, umshini wokugunda utshani, njll.
ukunikeza amaphuzu avelele (80% ngenhla), ukukhanya okuncane (50-80%), ingilazi engenalutho (20-50%) kanye nokukhanya (20% ngezansi) imikhiqizo noma izidingo
Uchungechunge Lomkhiqizo:
I-powder conductive emnyama nekhanyayo iyatholakala ukuze isetshenziswe ngaphakathi nangaphandle.
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 kwangaphambili: indawo engaphezulu kufanele ihlanzwe kahle ukuze kukhishwe amafutha nokugqwala. Ukusetshenziswa kochungechunge lwe-iron phosphating noma uchungechunge lwe-zinc olusezingeni eliphakeme lwe-phosphating lungathuthukisa ikhono lokuvikela ukugqwala.
Imodi yokwelapha: ukwakhiwa kwesibhamu esimanuwali noma okuzenzakalelayo
Izimo zokuphulukisa: 200 ℃ (i-workpiece lokushisa), imizuzu eyi-10

Amanothi:
1.Ukuhlola okungenhla kusebenzise amapuleti ensimbi awugqinsi angu-0.8mm anogqinsi oluyi-60-80 microns.
2.Inkomba yokusebenza ye-coating engenhla ingase ishintshe ngokushintsha kombala nokucwebezela.
Ukufakwa okumaphakathi:
9-12 sq.m./kg; ukujiya kwefilimu ama-microns angama-60 (abalwe ngesilinganiso sokusebenzisa impuphu engu-100%)
Ukupakisha nezokuthutha:
amabhokisi afakwe izikhwama polyethylene, net isisindo 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 livalwe emthonjeni womlilo, kude nomthombo wokushisa.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.
