I-Polyester Resin Powder Coating
Isingeniso Esijwayelekile:
Yenziwe nge-carboxyl polyester resin, i-pigment filler kanye ne-TGL njenge-ejenti elaphayo, enokumelana nesimo sezulu esiphezulu nokumelana ne-UV. Izakhiwo ezinhle zemishini, ubulukhuni obukhulu, ukumelana nokunwaya, ukumelana nokugqwala; Impahla yokulinganisa enhle, ifilimu ngokuyisisekelo ayinazo izimbobo, izimbobo ezinciphayo nokunye ukukhubazeka; Ingasetshenziselwa imikhiqizo yensimbi yangaphandle efana ne-air conditioner, izibani zangaphandle nezibani.
Uchungechunge Lomkhiqizo:
ukunikeza amaphuzu avelele (80% ngenhla), ukukhanya okuncane (50-80%), ingilazi engenalutho (20-50%) kanye nokukhanya (20% ngezansi) imikhiqizo noma izidingo
Izakhiwo Zomzimba:
Amandla adonsela phansi athile(g/cm3, 25℃) : 1.2-1.7
Ukusatshalaliswa kosayizi wezinhlayiya: 100% ngaphansi kwama-micron ayi-100 (Kungalungiswa ngokuya ngezidingo ezikhethekile zokudweba)
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: 190-200 ℃ (i-workpiece lokushisa), imizuzu eyi-10
Ukusebenza kwe-coating:

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:
8-11 sq.m./kg; ukujiya kwefilimu ama-microns angama-70 (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:
Ihlanzekile, yomile, ingena umoya, kude nokukhanya, izinga lokushisa legumbi elingaphansi kuka-30 ℃, futhi kufanele ivalwe emthonjeni womlilo, kude nomthombo wokushisa.Isikhathi sokugcina esisebenzayo yizinyanga eziyisi-6 kusukela ngosuku lokukhiqiza. Ngemva kwesikhathi sokulondoloza, ingaphinda ihlolwe futhi isetshenziswe futhi uma imiphumela ihlangabezana nezidingo. Zonke iziqukathi kufanele zipakishwe kabusha futhi zibuyiselwe emaphaketheni azo asekuqaleni ngemva kokusetshenziswa.
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.
