Choletsa moto chochokera ku TF-PU501 P ndi N cha thovu lolimba la PU
Chiyambi
TF-PU501 ndi chinthu choletsa moto chomwe chapangidwira thovu lolimba la PU. Ufa wake wa imvi ulibe halogen komanso wopanda zitsulo zolemera, uli ndi PH yosasunthika, sungathe kusungunuka m'madzi, utsi wabwino umatha kutsekeka, komanso umathandiza kwambiri poletsa moto.
Ngati makasitomala alibe zofunikira za kukula ndi mitundu ya tinthu, TF-pu501 ndi yoyenera kwambiri pa Pu yolimba ya zinthu zoletsa moto, zomwe zimapereka njira yabwino kwambiri yotetezera moto pa zinthu za PU zomwe zimagwiritsidwa ntchito kwambiri m'miyoyo yathu. M'dziko lamakono, kugwiritsa ntchito kwambiri zinthu za PU kwakhala kofunikira m'magawo osiyanasiyana. Kaya m'mafakitale a mipando, zomangamanga, zoyendera kapena ndege, zofunikira zotetezera moto ndizofunikira.
Kufotokozera
| Kufotokozera | TF-PU501 |
| Maonekedwe | Ufa wa imvi |
| P2O5zomwe zili (w/w) | ≥41% |
| Zomwe zili N (w/w) | ≥6.5% |
| pH value (10% aqueous suspension, pa 25ºC) | 6.5-7.5 |
| Chinyezi (w/w) | ≤0.5% |
Makhalidwe
1. Ufa wa imvi, umafutukuka ukatenthedwa, umagwira ntchito bwino poletsa utsi.
2. Kukana madzi bwino kwambiri, sikophweka kugwetsa, komanso kuletsa moto kwambiri.
3. Ma ayoni achitsulo cholemera opanda halogen. pH ndi yotetezeka komanso yokhazikika popanga ndi kugwiritsa ntchito, imagwirizana bwino, siyingagwirizane ndi zinthu zina zoletsa moto komanso zothandizira.
Kugwiritsa ntchito
TF-PU501 ingagwiritsidwe ntchito kokha ngati mankhwala osayaka moto kapena kugwiritsidwa ntchito limodzi ndi TEP pa thovu lolimba la polyurethane. Ikawonjezeredwa 9%, imatha kufikira pempho la OI la UL94 V-0. Ikawonjezeredwa 15%, imatha kugawa B1 pakuyaka kwa zipangizo zomangira ndi GB / T 8624-2012.
Komanso, utsi wa thovu ndi wochepera 100.
