Kev piav qhia tus cwj pwm

DB 886 yog lub pob khoom ruaj khov UV ua haujlwm siab uas tsim los

rau cov tshuab polyurethane (piv txwv li TPU, CASE, RIM cov ntawv thov ua npuas ncauj yooj ywm).

DB 866 muaj txiaj ntsig zoo hauv thermoplastic polyurethane (TPU). DB 866 kuj tseem siv tau rau hauv polyurethane coatings ntawm tarpaulin thiab pem teb nrog rau hauv cov tawv hluavtaws.

Cov ntawv thov

DB 886 muab kev ruaj khov UV zoo heev rau cov kab ke polyurethane.

Qhov ua tau zoo dua li cov txheej txheem UV stabilizer ib txwm muaj yog qhov tshwj xeeb tshaj yog pom tseeb hauv cov ntawv thov TPU pob tshab lossis xim sib dua.

DB 886 kuj tseem siv tau rau lwm cov polymers xws li polyamides thiab lwm yam yas engineering suav nrog aliphatic polyketone, styrene homo- thiab copolymers, elastomers, TPE, TPV thiab epoxies nrog rau polyolefins thiab lwm yam organic substrates.

Cov yam ntxwv/cov txiaj ntsig

DB 886 muab kev ua tau zoo dua thiab ua haujlwm tau zoo dua

dua li cov txheej txheem tswj lub teeb pom kev zoo ib txwm muaj:

Xim pib zoo heev

Kev khaws xim zoo dua thaum lub sijhawm raug UV

Txhim kho lub sijhawm ntev-thermal-stability

Ib qho tshuaj ntxiv

Yooj yim noj

Cov khoom tsim dawb mus rau me ntsis daj, hmoov dawb-ntws

Cov lus qhia rau kev siv

Cov theem siv rau DB 886 feem ntau yog nyob nruab nrab ntawm 0.1% thiab 2.0%

nyob ntawm seb cov substrate thiab cov txheej txheem ua haujlwm li cas. DB 866 siv tau ib leeg lossis ua ke nrog lwm cov khoom siv ntxiv xws li cov tshuaj antioxidants (hindered phenols, phosphites) thiab HALS lub teeb stabilizers, qhov twg feem ntau pom kev ua tau zoo synergistic. Cov ntaub ntawv kev ua tau zoo ntawm DB 886 muaj rau ntau yam kev siv
