Imiterere y'ibiranga

DB 886 ni paki yo kubungabunga imirasire ya UV ifite imikorere myiza cyane yagenewe

ku buryo bwa polyurethane (urugero: TPU, CASE, RIM flexible foam applications).

DB 866 ikora neza cyane muri polyurethane ya thermoplastic (TPU). DB 866 ishobora kandi gukoreshwa mu gusiga polyurethane ku mabati no hasi ndetse no mu ruhu rw'ubukorikori.

Porogaramu

DB 886 itanga ubushobozi bwo kurinda imirasire ya UV ku buryo butangaje.

Ubushobozi bwo kwiyongera ugereranije na sisitemu zisanzwe zo kubungabunga imirasire ya UV bugaragara cyane cyane mu gukoresha TPU ibonerana cyangwa irangi ryoroheje.

DB 886 ishobora kandi gukoreshwa mu zindi polymer nka polyamides n'izindi pulasitiki z'ubuhanga zirimo aliphatic polyketone, styrene homo- na copolymers, elastomers, TPE, TPV na epoxies ndetse na polyolefins n'izindi substrates z'umwimerere.

Ibiranga/inyungu

DB 886 itanga umusaruro mwiza kandi ikongera umusaruro

ugereranije na sisitemu zisanzwe zo kubungabunga urumuri:

Ibara ryiza cyane ry'ibanze

Ibara rigumana neza cyane mu gihe cyo kwibasirwa n'imiraba ya UV

Kongera ubushobozi bwo guhagarara neza igihe kirekire - ubushyuhe

Igisubizo cy'inyongera imwe

Biroroshye gupimwa

Ifu y'umusaruro iva ku mweru kugeza ku muhondo muto, itemba buhoro

Amabwiriza yo gukoresha

Ingano z'ikoreshwa rya DB 886 zikunze kuba hagati ya 0.1% na 2.0%

bitewe n'imiterere y'ibikoresho n'imiterere y'ibikoresho. DB 866 ishobora gukoreshwa yonyine cyangwa hamwe n'ibindi bikoresho by'ingenzi nka antioxydants (phenols zitinze, fosfite) na HALS light stabilizers, aho akenshi hagaragara imikorere ihuriweho. Amakuru y'imikorere ya DB 886 araboneka ku bikorwa bitandukanye
