Ubume beempawu

I-DB 886 yiphakheji ephezulu yozinzo ye-UV eyenzelwe

kwiinkqubo zepolyurethane (umz. TPU, CASE, RIM flexible foam applications).

I-DB 866 isebenza ngokukodwa kwi-thermoplastic polyurethane (TPU). I-DB 866 isenokusetyenziswa kwiingubo ze-polyurethane kwiseyile kunye nomgangatho kunye nakwisikhumba sokwenziwa.

Usetyenziso

I-DB 886 ibonelela ngozinzo olubalaseleyo lwe-UV kwiinkqubo ze-polyurethane.

Ukusebenza okwandisiweyo kwiinkqubo eziqhelekileyo zokuzinzisa kwe-UV kubonakaliswa ngokukodwa kwizicelo ze-TPU ezicacileyo okanye ezikhanyayo.

I-DB 886 ingasetyenziswa nakwezinye iipholima ezifana neepolyamides kunye nezinye iiplastiki zobunjineli ezibandakanya i-aliphatic polyketone, i-styrene homo- kunye ne-copolymers, i-elastomers, i-TPE, i-TPV kunye ne-epoxies kunye ne-polyolefins kunye nezinye i-substrates eziphilayo.

Iimpawu/izibonelelo

I-DB 886 ibonelela ngokusebenza okuphezulu kunye nokwanda kwemveliso

kwiinkqubo eziqhelekileyo zokuzinzisa ukukhanya:

Umbala wokuqala ogqwesileyo

Ukugcinwa kombala okuphezulu ngexesha lokuvezwa kwe-UV

Ukomelezwa kwexesha elide-uzinzo lwe-thermal

Isisombululo esisodwa esongezelelweyo

Easy dosable

Imveliso yenza uMhlophe ukuya kumthubi kancinane, umgubo oqukuqelayo okhululekileyo

Izikhokelo zokusetyenziswa

Amanqanaba okusetyenziswa kwe-DB 886 ngokuqhelekileyo aphakathi kwe-0.1 % kunye ne-2.0 %

kuxhomekeke kwi-substrate kunye neemeko zokucubungula. I-DB 866 ingasetyenziswa yodwa okanye idityaniswe nezinye izongezo ezisebenzayo ezifana ne-antioxidants (i-phenols ethintelekileyo, i-phosphites) kunye ne-HALS yokuqina kokukhanya, apho kuhlala kubonwa ukusebenza kwe-synergistic. Idatha yokusebenza yeDB 886 iyafumaneka kwizicelo ezahlukeneyo
