Ukwenziwa kwezinhlamvu
I-DB 886 iyiphakeji lokuzinza kwe-UV elisebenza kahle eliklanywe
kumasistimu e-polyurethane (isb. TPU, CASE, RIM flexible foam applications).
I-DB 866 isebenza kahle kakhulu ku-thermoplastic polyurethane (TPU). I-DB 866 ingasetshenziswa futhi embotsheni ye-polyurethane kuseyili naphansi kanye nasesikhumbeni sokwenziwa.
Izinhlelo zokusebenza
I-DB 886 inikeza ukuzinza okuvelele kwe-UV kumasistimu we-polyurethane.
Ukusebenza okukhuphukile kuzinhlelo ezijwayelekile zokuzinzisa kwe-UV kuvezwa ikakhulukazi ezinhlelweni ze-TPU ezinombala obala noma okhanyayo.
I-DB 886 ingasetshenziswa nakwamanye ama-polymers njengama-polyamides namanye amapulasitiki obunjiniyela ahlanganisa i-aliphatic polyketone, i-styrene homo- nama-copolymers, ama-elastomers, i-TPE, i-TPV nama-epoxies kanye nama-polyolefin namanye ama-substrates aphilayo.
Izici/izinzuzo
I-DB 886 inikeza ukusebenza okuphezulu kanye nokukhiqiza okukhulayo
phezu kwezinhlelo ezijwayelekile zokuzinzisa ukukhanya:
Umbala wokuqala omuhle kakhulu
Ukugcinwa kombala okuphezulu ngesikhathi sokuchayeka kwe-UV
Ukuqina kwesikhathi eside-okushisayo okuthuthukisiwe
Isixazululo sesengezo esisodwa
Kulula ukudoselwa
Umkhiqizo wenza Okumhlophe kuya kokuphuzi kancane, okuyimpushana egeleza mahhala
Imihlahlandlela yokusetshenziswa
Sebenzisa amazinga e-DB 886 ngokuvamile aphakathi kuka-0.1 % no-2.0 %
ngokuya nge-substrate nezimo zokucubungula. I-DB 866 ingasetshenziswa iyodwa noma ihlanganiswe nezinye izithasiselo ezisebenzayo ezifana nama-antioxidants (ama-phenols avinjiwe, ama-phosphites) kanye neziqinisi zokukhanya ze-HALS, lapho kuvame ukubonwa ukusebenza kwe-synergistic. Idatha yokusebenza ye-DB 886 iyatholakala kuzinhlelo zokusebenza ezahlukahlukene
