Ukuchazwa kwabalinganiswa

I-DB 886 yiphakheji yokuzinzisa i-UV esebenza kakuhle eyilelweyo

kwiinkqubo ze-polyurethane (umz. i-TPU, i-CASE, i-RIM flexible foam applications).

I-DB 866 isebenza kakuhle kakhulu kwi-thermoplastic polyurethane (TPU). I-DB 866 ingasetyenziswa nakwizinto zokugquma i-polyurethane kwi-tarpaulin nakwi-floor kunye nakwisikhumba esenziwe ngokwenziwa.

Izicelo

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

Ukusebenza okunyukileyo kwiinkqubo ze-UV stabilizer eziqhelekileyo kubonakala ngakumbi kwizicelo ze-TPU ezicacileyo okanye ezinemibala ekhanyayo.

I-DB 886 ingasetyenziswa nakwezinye iipolymer ezifana neepolyamides kunye nezinye iiplastiki zobunjineli kuquka i-aliphatic polyketone, i-styrene homo- kunye nee-copolymers, ii-elastomers, i-TPE, i-TPV kunye nee-epoxies kunye neepolyolefins kunye nezinye izinto eziphilayo.

Iimpawu/iingenelo

I-DB 886 inika ukusebenza okuphezulu kunye nokwanda kwemveliso

ngaphezu kweenkqubo zokuzinzisa ukukhanya eziqhelekileyo:

Umbala wokuqala ogqwesileyo

Ukugcinwa kombala okuphezulu ngexesha lokuvezwa yi-UV

Ukuphuculwa kozinzo lwexesha elide-ubushushu

Isisombululo esongezelelweyo esinye

Kulula ukuyithatha

Iifom zemveliso: Umgubo omhlophe ukuya kotyheli kancinci, ohamba ngokukhululekileyo

Izikhokelo zokusetyenziswa

Amanqanaba okusetyenziswa kwe-DB 886 adla ngokuba 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 nee-antioxidants (ii-phenols ezithintelweyo, ii-phosphites) kunye neziqinisi zokukhanya ze-HALS, apho kuhlala kubonwa ukusebenza okusebenzisanayo. Idatha yokusebenza ye-DB 886 iyafumaneka kwiindlela ezahlukeneyo zokusetyenziswa.
