I-polyurethane polymer Ukumanzisa kunye ne-Agents yokuSasaza (Uhlobo lwesinyibilikisi)
I-Polyurethane yepolymer Ukumanzisa kunye ne-Agents yokuSasaza(uhlobo lwesinyibilikisi)
KEPERDISP®-639
I-dispersant yendalo yonke inokunciphisa ngokufanelekileyo i-viscosity, kwaye ubumnyama bombala we-paste buhle kakhulu xa ugaya i-high-pigment carbon black kunye nenani eliphezulu lokongeza.
Isishwankathelo semveliso
I-KEPERDISP®-639 yinjongo eqhelekileyo ye-polyurethane dispersant. Iyakwazi ukusasaza ngokufanelekileyo ii-pigments ezahlukeneyo kwiinkqubo ezahlukeneyo ze-resin.Especially inconywa ukugaya i-high pigment carbon black (kunye nokudibanisa okuphezulu)
Idatha ebonakalayo
1. Isithako esisebenzayo: i-molecular weight polyurethane ephezulu
2. Umxholo: 40±2%
3.I-Solvent: I-butyl acetate /PMA
Iimpawu zemveliso
I-1.Ukuhambelana okugqwesileyo, iinkqubo ezibanzi zokusetyenziswa, i-dispersant jikelele, inokusasaza i-inorganic, i-organic pigments, i-carbon black.
2.Umphumo ogqwesileyo wokunciphisa i-viscosity, ukusabalalisa umbala obalaseleyo we-pigment.
Ngokukodwa xa usasaza umphezulu wekhabhoni emnyama enomthamo ophezulu wokongeza, ubumnyama befilimu yepeyinti buvelele kakhulu, kwaye iglosi iphezulu ngaphandle komthunzi wenkungu.
Uvavanyo lwesicelo
Sivavanye ukusebenza kokusasazwa kolu luhlu lweemveliso (KEPERDISP-6463/639/635, B-163, njl.) kwiinkqubo ze-hydroxy-acrylic acid.
Imibala yethu esasazekileyo: iPhthalein blue
Izinto zokuvavanya kunye nothelekiso: ukusebenza kakuhle kokusasazwa, i-viscosity, ukuguqulwa kombala, ukungafihli, amandla okulwa ne-flocculation, uzinzo lokugcina.
Iziphumo zovavanyo:
Ukusasazwa kakuhle
Izixhobo zokusasaza: ilitye lokusila, Ukulunga kokusasazwa: 5 µ
Ixesha lokusasazwa ukuya kwi-fineness: Bonke bafikelele kwi-fineness yokusila kwiiyure ezi-2.
Viscosity:Idatha eneenkcukacha iboniswe kwitheyibhile engezantsi. Impembelelo yokunciphisa i-viscosity ye-6468 ingcono kancinci, ngelixa ezinye zisondele.
| B-163 | 6468 | 639 | 635 | ||
| Ukulunga (µm) | 5µm | 5µm | 5µm | 5µm | |
| Viscosity (mPa.s) | 6rpm | 11800 | 11300 | 12200 | 12500 |
| 12rpm | 7550 | 7300 | 8100 | 8150 | |
| 30rpm | 3980 | 3900 | 4420 | 4400 | |
| 60rpm | 2320 | 2290 | 2520 | 2530 | |
3.Uzinzo lokugcinwa:Emva kweentsuku ezili-15 zogcino olutywiniweyo kwi-50℃, ukucoleka kweepasti zokusila akuzange kutshintshe. Ukunyuka kwe-viscosity kuyafana.
Iziphumo zovavanyo zibonisa ukuba iimpawu ezibanzi ze-KEPERDISP®-6468 zisondele kakhulu kwi-B-163 kwiinkqubo ze-hydroxy-acrylic acid. Ikhono lokunciphisa i-viscosity kunye nokusebenza kombala wokuphuhliswa kwe-6468 kungcono.Nceda uqhagamshelane nathi ngengxelo yovavanyo olucacileyo.
