Ukuchazwa kwezinhlamvu

I-DB 886 iyiphakheji yokuzinzisa i-UV esebenza kahle kakhulu eyenzelwe

kwezinhlelo ze-polyurethane (isb. i-TPU, i-CASE, izinhlelo zokusebenza ze-foam eziguquguqukayo ze-RIM).

I-DB 866 isebenza kahle kakhulu kwi-thermoplastic polyurethane (TPU). I-DB 866 ingasetshenziswa nasezimbozweni ze-polyurethane ezifakwe ethangini kanye naphansi kanye nasesikhumbeni sokwenziwa.

Izicelo

I-DB 886 inikeza ukuzinza kwe-UV okuvelele ezinhlelweni ze-polyurethane.

Ukusebenza kahle okukhulu kunezinhlelo ezivamile zokuzinzisa i-UV kubonakala kakhulu ekusetshenzisweni kwe-TPU okubonakalayo noma okukhanyayo.

I-DB 886 ingasetshenziswa nakwamanye ama-polymer afana nama-polyamides namanye amapulasitiki obunjiniyela afaka phakathi i-aliphatic polyketone, i-styrene homo- kanye nama-copolymer, ama-elastomers, i-TPE, i-TPV kanye nama-epoxies kanye nama-polyolefin kanye nezinye izinto eziphilayo.

Izici/izinzuzo

I-DB 886 inikeza ukusebenza okuphezulu kanye nokukhiqiza okwandisiwe

ngaphezu kwezinhlelo zokuqinisa ukukhanya ezivamile:

Umbala wokuqala omuhle kakhulu

Ukugcinwa kombala okuphezulu ngesikhathi sokuchayeka ku-UV

Ukuqina kokushisa kwesikhathi eside okuthuthukisiwe

Isixazululo esingeziwe esisodwa

Kulula ukukala

Ukwakheka komkhiqizo: Okumhlophe kuya kokuphuzi kancane, impuphu egeleza ngokukhululeka

Iziqondiso zokusebenzisa

Amazinga okusetshenziswa kwe-DB 886 ngokuvamile aphakathi kuka-0.1% no-2.0%

kuye ngezimo ze-substrate kanye nokucubungula. I-DB 866 ingasetshenziswa yodwa noma ihlanganiswe nezinye izithasiselo ezisebenzayo ezifana nama-antioxidants (ama-phenol athintekile, ama-phosphite) kanye nama-HALS light stabilizers, lapho kuvame ukubonakala khona ukusebenza okusebenzisanayo. Idatha yokusebenza ye-DB 886 iyatholakala ezinhlelweni ezahlukahlukene.
