Polyurethane Powder Coating
Isingeniso Esijwayelekile:
Izembatho zempushana ezenziwe nge-hydroxyl polyester resin, enezici ezinhle kakhulu zamakhemikhali, nokuhlobisa okuhle kakhulu, ukulinganisa, ukumelana namakhemikhali, ukumelana nesimo sezulu kanye nokumelana nowoyela okuqinile. Ifanele ukumbozwa kwensimbi yebhayisikili, imoto, isithuthuthu, umshini wokugcwalisa amafutha kanye nemishini yezolimo enesidingo esikhulu sokumelana namakhemikhali nokumelana nowoyela.
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℃): 1.4-1.7
Ukusatshalaliswa kosayizi wezinhlayiya: 100% ngaphansi kwe-micron eyi-100 (Kungashintshwa ngokuya ngezidingo ezikhethekile zokumboza)
Izimo zokwakha:
Ukwelashwa ngaphambi kwesikhathi: ukwelashwa kwangaphambili okuhlukene kwama-substrates ahlukene (ukwelashwa kwe-phosphating, ukwelashwa kokufuthwa ngomsindo, ukwelashwa kokuchama)
Imodi yokwelapha: ukwakhiwa kwesibhamu esimanuwali noma okuzenzakalelayo
Izimo zokuphulukisa: 200 ℃ (i-workpiece lokushisa), imizuzu eyi-10
Ukusebenza kwe-coating:
| Into yokuhlola | Indinganiso yokuhlola noma indlela | Izinkomba zokuhlola |
| ukumelana nomthelela | ISO 6272 | 50kg.cm |
| ukuhlolwa kwenkomishi | ISO 1520 | 8mm |
| i-adhesive force (indlela ye-lattice yomugqa) | ISO 2409 | 0 izinga |
| ukugoba | ISO 1519 | 2mm |
| ubulukhuni bepensela | I-ASTM D3363 | 1H-2H |
| ukuhlolwa kwesifutho sikasawoti | ISO 7253 | > amahora angu-500 |
| ukuhlolwa okushisayo nokunomswakama | ISO 6270 | > 1000 amahora |
| ukumelana nokushisa | 150℃/24 amahora (amhlophe) | ukugcinwa kokukhanya okuhle kakhulu, umehluko wombala≤0.3-0.4 |
Amanothi:
1.Ukuhlola okungenhla kusetshenziswe amapuleti ensimbi awugqinsi angu-0.8mm anogqinsi oluyi-50-70 microns.
2.Inkomba yokusebenza ye-coating engenhla ingase ishintshe ngokushintsha kombala nokucwebezela.
Ukufakwa okumaphakathi:
9-11 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:
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.
