Astaamaha

DB 886 waa xirmo xasilinta UV waxqabadka sare ah oo la qorsheeyay

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

DB 866 ayaa si gaar ah ugu wax ku ool u ah polyurethane thermoplastic (TPU). DB 866 waxa kale oo loo isticmaali karaa dahaarka poliurethane ee taarpaulin-ka iyo sagxadda sagxadda iyo sidoo kale maqaar synthetic ah.

Codsiyada

DB 886 waxay siisaa xasiloonida UV ee nidaamyada polyurethane.

Waxtarka korodhka ee nidaamyada xasilinta UV ee caadiga ah ayaa si gaar ah loogu dhawaaqaa codsiyada TPU ee hufan ama midab khafiif ah.

DB 886 waxa kale oo loo isticmaali karaa polymers kale sida polyamides iyo balaastikada kale ee injineernimada oo ay ku jiraan polyketone aliphatic, styrene homo-iyo copolymers, elastomers, TPE, TPV iyo epoxies iyo sidoo kale polyolefins iyo substrates kale organic.

Tilmaamaha/faa'iidooyinka

DB 886 waxay bixisaa waxqabad heersare ah iyo wax soo saar kordhay

Nidaamyada xasilinta iftiinka caadiga ah:

Midab bilow ah oo heer sare ah

Haysashada midabka sare inta lagu jiro soo-gaadhista UV

Xasilooni kuleyl-dheer oo la xoojiyey

Xalka kaliya ee lagu daro

Si fudud loo qaadan karo

Foomamka badeecada Caddaan ilaa waxoogaa huruud ah, budo bilaash ah

Tilmaamaha isticmaalka

Isticmaalka heerarka DB 886 waxay caadi ahaan u dhexeeyaan 0.1 % iyo 2.0 %

ku xiran tahay substrate iyo xaaladaha processing. DB 866 waxaa loo isticmaali karaa kaligiis ama lagu daro daroogooyinka kale ee shaqeynaya sida antioxidants (phenols xannibay, fosfit) iyo HALS xasiliyeyaasha iftiinka, halkaas oo inta badan lagu arko waxqabadka isdhexgalka. Xogta waxqabadka DB 886 ayaa diyaar u ah codsiyo kala duwan
