Astaamaha

DB 886 waa xirmo xasilin UV oo waxqabad sare leh oo loogu talagalay

nidaamyada polyurethane (tusaale ahaan codsiyada xumbo dabacsan ee TPU, CASE, RIM).

DB 866 si gaar ah ayuu waxtar ugu leeyahay thermoplastic polyurethane (TPU). DB 866 waxaa sidoo kale loo isticmaali karaa dahaarka polyurethane ee ku yaal tarpaulin iyo sagxadaha iyo sidoo kale maqaar macmal ah.

Codsiyada

DB 886 wuxuu bixiyaa xasillooni UV oo heer sare ah nidaamyada polyurethane.

Waxtarka kordhay ee nidaamyada xasilinta UV-ga caadiga ah ayaa si gaar ah loogu muujiyaa codsiyada TPU ee hufan ama midabka khafiifka ah.

DB 886 waxaa sidoo kale loo isticmaali karaa polymers kale sida polyamides iyo balaastikada injineernimada kale oo ay ku jiraan aliphatic polyketone, styrene homo- iyo copolymers, elastomers, TPE, TPV iyo epoxy iyo sidoo kale polyolefins iyo substrates kale oo dabiici ah.

Sifooyinka/faa'iidooyinka

DB 886 wuxuu bixiyaa waxqabad heer sare ah iyo wax soo saar kordhay

nidaamyada xasilinta iftiinka ee caadiga ah:

Midab bilow ah oo aad u fiican

Haynta midabka oo heer sare ah inta lagu jiro soo-gaadhista UV

Xasilloonida muddada-dheer-kulka oo la xoojiyay

Xal hal-ku-dar ah

Si fudud loo qaadan karo

Badeecadu waxay samaysaa budo cad ilaa huruud ah oo si xor ah u socota

Tilmaamaha isticmaalka

Heerarka isticmaalka ee DB 886 waxay caadi ahaan u dhexeeyaan 0.1% iyo 2.0%

iyadoo ku xiran xaaladaha substrate-ka iyo habaynta. DB 866 waxaa loo isticmaali karaa kaligiis ama iyadoo lagu darayo waxyaabo kale oo shaqeynaya sida antioxidants (phenols-ka xanniban, phosphites) iyo xasiliyeyaasha iftiinka HALS, halkaas oo inta badan lagu arko waxqabad isku-dhafan. Xogta waxqabadka ee DB 886 ayaa loo heli karaa codsiyo kala duwan.
