Fa'ailoga

DB 75 o le vevela vai ma le malamalama faʻamautu faiga fuafuaina mo polyurethanes

Fa'atatauga

DB 75 o loʻo faʻaaogaina i polyurethanes e pei ole Reaction Injection Molding (RIM) polyurethane ma polyurethane thermoplastic (TPU). O le faʻafefiloi e mafai foʻi ona faʻaaogaina i faʻamaufaʻailoga ma faʻapipiʻi faʻaoga, i le polyurethane faʻapipiʻi i luga o tapoleni ma fola faʻapea foʻi ma le paʻu synthetic.

Fa'apitoa/fa'amanuiaga

O le DB 75 e puipuia ai le faʻaogaina, malamalama ma le tau faʻaleagaina
o oloa polyurethane e pei o seevae seevae, meafaifaaili ma faitotoʻa panels, uili uili, faʻamalama faʻamalama, ulu ma lima malolo.
DB 75 e mafai ona faigofie ona faaopoopo i faiga polyurethane aromatic po o aliphatic mo moldings thermoplastic, foams semi-malosi, in-moli pa'u, dope talosaga. E mafai ona fa'aoga i mea fa'alenatura ma mea fa'amalama. DB 75 e sili ona talafeagai mo le saunia o paʻu lanu mautu malamalama mo faiga ua taʻua i luga.
Fa'amanuiaga fa'aopoopo:
faigofie ona pamu, sasaa le vai e mafai ai ona taulimaina e aunoa ma se pefu, fua otometi ma fa'apu'upu'u taimi fa'afefiloi
pusa vai uma; leai se fa'apala o fa'aopoopoga i le vaega polyol tusa lava pe maualalo le vevela
tetee i le exudation/crystallization i le tele o faiga PUR

Fomu o oloa Ma'a, sina samasama vai

Taiala mo le faaaogaina

Ole maualuga ole fa'aoga ole DB 75 ole va ole 0.2% ma le 1.5%, e fa'atatau ile mea e fa'aogaina ma le fa'atinoga o mana'oga o le talosaga mulimuli:
Fa'afu fa'atasi vaega lua fa'agaoioi 0.6 % – 1.5 %
Fa'apipi'i 0.5 % – 1.0 %
Fa'amaufa'ailoga 0.2 % – 0.5 %
Ole tele o fa'amatalaga fa'atinoga o le DB 75 o lo'o avanoa mo le tele o talosaga.
