Ubume beempawu
I-DB 886 yiphakheji ephezulu yozinziso 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 kwi-TPU ecacileyo okanye ekhanyayo ye-TPU.
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 aqheleke phakathi 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
