Ukwenziwa kwezinhlamvu

I-DB 886 iyiphakeji lokuzinza kwe-UV elisebenza kahle eliklanyelwe

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

Ukuzinza okuthuthukisiwe kwesikhathi eside-okushisayo

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
